Referring more in detail to the drawings:

As required, detailed embodiments of the present invention are disclosed herein, however, it is to be understood that the disclosed embodiments are merely exemplary of the invention which may be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriate detailed structure.

The reference numeral 1 designates generally an apparatus adapted for splicing wires by crimping an open sided connector sleeve 2 onto the ends of two wires that are preferably one wire each from

cable portions

3 and 4 of a communication cable with the cable portions each containing a plurality of wires. It is sometimes necessary to splice communication cables such as those used in the telephone industry either after repair work on the cable or when joining two cables together. Normally the splicing work is done at in-field locations such as in a manhole where working area is at a minimum. For splicing, an operator must separate and match wires from each of the

cable portions

3 and 4 and effect a splice therebetween and because of the large number of wires generally contained within a communication cable, the splicing process is time consuming and results in operator fatigue. It is also necessary to effect consistent electrical continuity between the spliced wi es so as to prevent later interruption of 5 service which would require resplicing of the wires.

The apparatus 1 preferably is compact, portable and adapted for easy operation requiring a minimum of operator performed steps. In the form of the apparatus shown, feeding means 5 are provided to sequentially feed a connector sleeve 2 into a crimping station or means 6 where it is held in a wire receiving position. Preferably, the connector sleeves 2 are in an elongate chain in end to end relation with the leading or end connector sleeve 2 being cut or otherwise separated from the remainder of the chain by cutting means 6' after it is in the receiving position. Loading means 7 are mounted on the apparatus 1 and are operable to hold and control a pair of wires 8 and deposit same into a connector sleeve 2 at the receiving position and hold them therein until a precrimp is applied to the connector sleeve 2. The final crimp is applied to the connector sleeve 2 after partial retraction of the loading means 7, to effect the electrical connection between the wires 8. Ejector means 9 are actuated after crimping and eject the crimped connector sleeve 2 and the spliced wires 8 from the apparatus 1. Preferably the apparatus 1 is adapted for crimping two connector sleeves 2 simultaneously in splicing two pairs of matched wires with each pair of wires being spliced by a respective connector sleeve.

The apparatus 1 includes a support 12 having means thereon operable to actuate the various parts of the apparatus in sequential order. In the illustrated structure, the actuating means uses a reciprocating movement with cams, arms and parts actuated in response thereto and includes an operator or slide member 13 moveably mounted on the support 12. The slide 13 shown includes two

plates

14 and 15 each positioned on an opposite side of the support 12 and suitably secured together. Guide means are provided for the slide. 13 which, as shown, includes an opening 16 through the support member 12 and spaced apart bearings 17, such as rollers, secured between the

plates

14 and 15 and engaged with ways 18 which in the structure shown are parallel side edges defining the opening 16. The guide means permits the slide 13 to reciprocably move up and down with a minimum of play. Means are provided for effecting reciprocating movement of the slide 13 and preferably include an extendable ram 19 mounted on the support 12 and operatively connected to the slide 13. The ram 19 can be either hydraulic or pneumatic and connected to a pressurized fluid supply system (not shown) by lines 20. The cylinder 2] of the ram 19 is mounted on the support 12 as by a bottom pivot mount 22 and the piston rod 23 is connected to the slide 13 preferably with a U-shaped member or clevis 24 pivotally connected to a bracket 25 by a pivot pin 26 with the bracket 25 being secured to the slide 13.

The connector sleeve means, in the illustrated structure, includes a feed housing 27 mounted on the support 12 and having

channels

28 and 29 therein. defining a path of movement and receiving elongate chains 30 of connector sleeves 2 in end to end relation from a pair of rolls 31 containing the chains 30. The

channels

28 and 29 are in side by side relation on opposite sides of the support member 12. Preferably the housing 27 is movable. for a purpose later described, and in this regard the support 12 has a pair of slots 32 therethrough each receiving a respective bearing 33, such as a roller bearing, therein which are secured to a bracket 34 of the housing 27. The bearings 33 guide the housing 27 during movement as does a portion of the support 12 which extends through a slot 35 in a portion of the housing 27.

The feed means 5 includes apparatus to sequentially and incrementally move the chains 30 of connector sleeve 2 into the crimping means 6, preferably, with the sleeves 2 being moved forward one sleeve at a time. An arm 36 is pivotally mounted on the support member 12 with a pivot pin 37, said arm 36 is spaced to one side of the slide and preferably has a generally upstanding portion and a portion extending from the pivot pin 37 toward the slide 13. An end 38 of the arm is adapted to engage a roller 39 mounted on the slide 13 and moveable therewith whereby engagement between the roller 39 and the end 38 will urge the arm 36 to pivot clockwise, as illustrated in FIG. 5, upon downward movement of the slide 13. A spring 40 is connected to the arm 36 and the support 12 and biases the arm so as to pivot counter clockwise when the slide 13 moves upwardly and the spring 40 retains the arm in its counter clockwise position when the roller 39 is out of engagement with the end 38. The end 38 is shaped and positioned to be engaged in the lower portion of the downward stroke of the slide 13 and provide the necessary movement of the upper end of the upstanding portion of the arm 38 to advance a sleeve in to the wire receiving position.

Adjacent connector sleeves 2 in each of the chains 30 have a slot 42 therebetween adapted to receive portions of the feeding means therein to facilitate movement of the connector sleeve 2 into the crimping means 6. Guide members shown as a pair of parallel guide rods 43 are secured to portions of the housing 27 and positioned on opposite sides of the support 12. A support block 44 has a pair of guide bores (not shown) therethrough each having a respective guide rod 43 extending therethrough for slideably mounting the support block on the guide rods. The support block 44 has a portion 45 extending through an opening 46 through the support 12 which has sufficient height to permit up and down movement of the support block 44. A pair of fingers 47 are each pivotally and slidably mounted on a respective guide rod 43 by same extending through a guide bore 48 with the fingers 47 being contained between two walls defining a respective slot 49 whereby the fingers 47 are moveable with the support block 44 along the guide rods 43. A link 52 has opposite ends with one end pivotally connected to an upper end 53 of the arm 36 and the other end pivotally connected to the support block 44, whereby movement ofthe arm 37 reciprocably moves the support block 44 and the fingers 47 along the guide rods 43. In the illustrated structure. clockwise movement of the arm 36 effects movement of the support block 44 toward the wire receiving position and counter clockwise movement of the arm 36 effects movement of the support block 44 away from the wire receiving position. Springs 54 are secured to portions of the fingers 47 and the support block 44 and bias connector sleeve engaging detent portions or ends 55 to move toward the support 12 and into the slots 42 (FIG. 7.)

The housing 27 is operably connected to the slide 13 for selectively effecting the movement thereof. As illustrated (FIG. 8) a lift member 57 having cars 58 and 59 projecting from opposite sides thereof is rotatably secured to the support 12 by a pivot pin 60. The car 58 is adapted to engage a shoulder 61 on the bracket 34 and the ear 59 is adapted to engage reciprocal cam means 62, movable with the slide member 13, to position and time movement of the housing 27 at a predetermined point of down movement of the slide 13. Preferably, the cam means 62 has a shoulder 63 which engages the ear 59 and urges the lift member 57 to pivot about the pivot pin 60 and move the ear 58 into engagement with the shoulder 61 to effect upward movement of the housing 27. As shown the cam means 62 is elongate and retains the feed housing in the up or feeding position for a predetermined length of down stroke of the slide. When the cam means 62 moves out of engagement with the car 59 the lift member 57 is released and is allowed to pivot back to its normal position to allow the housing 27 to move to its down position under the influence of gravity. A spring member 64 is mounted on the support member 12 and is operable to engage the lift member 57 in such a manner as to bias the lift member to maintain the cars 58 and 59 in a position for engagement of the car 59 with the shoulder 63 on the downstroke of the slide 13.

Feeding of the connector sleeves 2 is effected with the housing 27 in the up position with each stroke of the arm 36 moving the chains forward the length of one connector sleeve and feeding connector sleeves to the wire receiving position. Cam blocks 66 are secured to opposite sides of the support member 12 and positioned beneath the support block 44 and have a length slightly greater than the length of the stroke of movement of the support block 44. The earns 66 each have an upwardly facing cam surface 67 which are inclined downwardly toward the support 12 and are engageable with the lower disposed ends 68 of the fingers 47 on downward movement of the feed housing 27. Engagement between the fingers 47 and the cam surfaces 67 moves the lower ends 68 of the fingers 47 inwardly and pivots the fingers to move the detent portions 55 out of the slots 42 and out of engagement with the connector sleeves 2, the retracted position allowing movement of the block 44 and fingers 47 to a feed start position on the backstroke of the arm 36 by the spring when the slide movement disengages the roller 39 from the lower end of the arm 36. The fingers 47 will be maintained in their open or retracted position until the housing 27 moves upwardly to disengage the cam surface 67 and the fingers 47, wherein same are returned by springs 54 to a position in slots 42 of the next two adjacent connector sleeves in the chains 30. Means are provided in the feed housing 27 to prevent the chains 30 from sliding out of their

respective channels

28 and 29 under the influence of gravity. it is preferred to have the means hold the chains with a light force that will not interfere with feeding movement effected by the fingers 47, and in the illustrated structure the engagement is frictional by a pair of retaining members 69 mounted on the feed housing and extending into openings 70 therein and engaging the respective chain 30 of connector sleeves to retain same within their

respective channels

28 and 29.

The crimping means 6 includes means which will preferably simultaneously crimp two connector sleeves 2 onto wires 8 loaded therein. In the illustrated struc ture the crimping means 6 includes a pair of crimping members 72 each having a crimping jaw portion 73 with the crimping members 72 being pivotally mounted on the support member 12 such by bearing blocks 74 secured to the support 12 and having pivot pins 75 extending therethrough and through a portion of the respective crimping member 72. One of the crimping jaws 73 is positioned on each side of the support member 12 and are in opposed relation with an anvil member 76 positioned therebetween whereby connector sleeves 2 which are to be crimped are each positioned in the wire receiving position between a respective crimping jaw 73 and one side of the anvil 76. Shoulder forming members 77 are secured to the support 12 extending therefrom toward respective crimping jaws 73 with each having an upwardly facing shoulder 78 for engaging the bottom surface of the connector sleeve 2 to support same between the crimping jaw 73 and the anvil 76. Preferably the anvil 76 is a portion of the support member 12. The crimping members 73 are sub stantially identical and have a depending arm portion 79 extending downwardly therefrom and spaced from the support member 12 and the slide member 13.

Means are provided for effecting crimping movement of the crimping jaws 73 and in the illustrated structure (FIG. 10), cam members 81 are secured to the slide 13 and movable therewith. The cams each have a multi step cam surface portion 82 extending outwardly from the

respective plate

14 and 15 and are engageable with respective arm portions 79. Preferably each of the arm portions 79 has a roller 83 mounted adjacent to the bottom end thereof for engagement with the respective cam surface portions 82. Movement of the earns 81 effects pivoting movement of the crimping members 72. The cam surfaces 82 each preferably have at least two steps thereon so that the jaws 73 will move to a partially closed position and then a fully closed position providing a precrimp and a final crimp respectively to the connector sleeve 2. When the slide 13 is in the down position the jaws 73 are open and as the slide 13 moves upwardly the cam surface 82 urges the jaws 73 to move toward one another to effect the crimping of the connector sleeves. Spring members 84 are secured to the support 12 and engage the arms 79 to bias same to a position where the jaws 73 remain in the open position until closed by upward movement of the slide 13 and to maintain the rollers 83 in engagement with the respective cam surface 82.

The crimping means 6 in the illustrated structure includes means to help hold the connector sleeves 2 in position between the crimping jaws 73 and the anvil 76 when the loading means 7 insert the wires 8 into the respective connector sleeves 2. Gripper means are provided for each of the jaws 73 and are substantially identical. As illustrated the gripper means includes an arm member 86 pivotally mounted on each of the crimping members 72 such as with a pivot pin 87, with the pivot pins 87 each being secured to a respective extension portion 88 of the crimping members 72. Each of the arms 86 has a pair of gripping pins 89 (FIG. 12) thereto and extending through openings 90 through the crimping jaws 73 with the gripping pins 89 having pointed or sharpened end portions 91 selectively engageable with the respective connector sleeve 2 to hold same in the wire receiving position between the crimping jaw 73 and the anvil 76 when the crimping jaws 73 are in their open position. An elongate rod 92 has one end thereof connected to the respective arm 86 and has the lower portion thereof reciprocably supported by a respective bracket member 93 which is secured to the slide member 13 for movement therewithv A spring 94 is mounted on each of the rods 92 and is retained thereon by a respective collar 95 with the springs 94 being compressible between the respective bracket member 93 and the respective collar 95. Each of the rods 92 has a stop member 96 secured thereon and positioned between the respective bracket member 93 and arm 86.

At a predetermined position on the downstroke of the slide 13 the bracket members 93 each engage the respective spring 94 inducing compression therein and causing the arms 86 to pivot and extend the gripping pins 89 outwardly of the jaws 73 toward the anvil 76. On upward movement of the slide 13 the compression in the springs 94 is released permitting the pins 89 to be released from engagement with the connector sleeve 2. The stop members 96 are engaged by the bracket members 93 upon further upward movement and force the arms 86 to pivot about the pins 87 and retract the gripping pins 89 from their extended position through the crimping jaws 73.

The loading means 7 are mounted on the support member 12 and are operably connected to the slide member 13 for operation in response to movement of the slide for loading preselected wires into the respective connector sleeves 2 and hold same in position until a precrimp is applied to the connector sleeves 2. In the illustrated structure the loading means includes a pair of loading

arms

99 and 100 which are swing-ably mounted on a mounting block 101 which in turn is fixed to the support member 12. Shafts 102 are rotatably mounted on the mounting block 101 and are disposed in angled relation as are the

arms

99 and 100. The

arms

99 and 100 are each mounted on a respective shaft 102 with the adjacent ends ofthe shaft 102 having a bevel gear 103 thereon and meshing whereby movement of one of the arms effects movement of the other arm simultaneously. Each of the

arms

99 and 100 has a loading head 104 with four pairs of fingers 105 thereon, the fingers being adapted to receive wires 8 therebetween, to hold same for loading. The fingers 105 are suitably secured to the loading head 104 and as shown, same are received in slots 106 with the fingers 105 having a head portion 107 receivable in an enlarged portion of slot 106 which is preferably round to allow pivoting movement of the fingers 105. As shown, the slot 106 diverges from the enlarged portion to provide clearance for pivoting movement of the fingers 105. A pin 108 extends through openings 109 of the fingers 105 to prevent lateral movement thereof and has a spring 110 thereon positioned in a bore 111 in the loading head 104 to bias the fingers 105 to a loading position as best seen in FIG. 9. When the precrimp is applied to the connector sleeves 2, as best seen in FIG. 15, the fingers 105 pivot so as to prevent deformation or damage thereto. The spring 110 causes the fingers 105 to resiliently grip the wires 8 therebetween. As il- Iustrated, the pairs of fingers 105 for gripping each of the wires 8, as best seen in FIG. 6, are in generally parallel relation with the other pairs of fingers on the respective loading head 104 whereby the wires 8 on each of the loading heads 104 are held in generally parallel relation.

Drive means are provided to operably connect the

loading arms

99 and 100 to the slide member 13 to effeet and time movement thereof. In the illustrated structure (FIG 15). a lever arm 113 is pivotally mounted on the plate 14 and extends through

slots

114 and 115 in the

plates

14 and 15 respectively and through an opening 116 through the support member 12. A push rod 117 is reciprocably mounted in a guide bore 118 through a bracket 119 which is suitably secured to the support 12. An end 120 of the push rod 117 is engageable with a cam surface 121 of the lever arm 113 with the cam surface 121 being contoured in such a manner as to urge the push rod 117 to move in response to movement of the slide 13. The cam surface 121, as illustrated, is comprised of a straight portion 122 with an inclined portion 123 between the straight portion 122 and a second straight portion 124. On upward movement of the slide 13 the push rod 117 begins axial movement when the end 120 engages the inclined portion 123 and after passing the incline portion 123 the straight portion 124 will hold the push rod 117 in an extended position during the remainder of the upstroke of the slide 13.

A lever or crank arrangement is mounted on the bracket 119 and is comprised of a pair of

lever arms

126 and 127 each secured to a common shaft 128 at opposite ends thereof with the shaft 128 being rotatably mounted in a support block 129 which is suitably secured to the bracket 119. As described above the end 120 is in engagement with the lever arm 113 and can be provided with a roller 131 and the opposite end of the push rod is in engagement with the lever arm 126, to effect movement of the

levers

126 and 127 in response to movement of the slide 13. A spring member 132 is suitably connected to the lever 126 and biases the lever arrangement to a rest position with the push rod 117 in a non extended position and in engagement with the cam surface 121. A link 133 is connected to the lever 127 and to a gear segment 134 which is rotatably mounted on the mounting block 101. A gear 135 is secured to the shaft 102 of the loading arm 99 and meshes with the segment 134. The link 133 is secured to the gear segment 134 at a distance spaced from the pivot point thereof whereby movement of the push rod 117 causes the lever 127 to pivot on the shaft 128 causing the link 1333 to move and thereby effect turning movement of the segment 134 which in turn effects rotation of the gear 135 and swinging movement of the

arms

99 and 100. The

arms

99 and 100 move from a rest position as seen in FIG. 6 to a loading or wire depositing position as shown in FIG. 15 and are operable to position the wires 8 in the connector sleeves 2 so the wire free ends are spaced between ends of the connector sleeve and hold the wires therein until the precrimp is applied to the connector sleeves 2.

The cam 121 of lever arm 113 operates only on a portion of the upstroke of the slide member 13 and then is released to an inactive position to the loading arms are not moved on the down stroke of the slide member. A latch and timed release is provided for this purpose and they control the action of the lever arm 113. In the illustrated structure (FIG. 15) the bottom end of the lever arm 113 extends outwardly from the plate 15 and has a slot 136 therethrough for receiving a latch member 137 which holds same in the position extending through the

plates

14 and 15 and the support member 12. The latch 137 is moveable on the slide member 13 and has a notch 138 therethrough adjacent the lever arm 113. A stop member 139 is secured to the support member 12 and engages an end 140 of the latch 137 and is held in engagement therewith by'a tion 142 which engages a member 143 that is secured to the support member 12 and has an inclined surface portion 144 whereupon engagement between the

inclined surfaces

142 and 144 urges the latch 137 to move laterally to align the notch 138 with the end of the lever arm 113 and release same to pivot back through the

plates

14 and 15 and the support member 12 allowing the arrangement of

levers

126 and 127 to return to their normal position under bias of the spring 132. Return to the normal position of the push rod 117 allows the loading

arms

99 and 100 to return to their normal position due to the bias of spring 132. It is desirable to provide the apparatus 1 with means to assure that the loading

arms

99 and 100 retract sufficiently after the precrimp is applied to the connector sleeves so that the fingers 105 are clear of the connector sleeves before the final crimp is applied. In this regard an arm member 145 extends from the gear segment 134 and has a shoe 146 on the end thereof which is engageable with an elongate member 147 that is secured to the slide 13 and moveable therewith. The member 147 has an end 148 which is inclined and upon completion of the upstroke of the slide 13 the end 148 engages the shoe 146 causing the gear segment 134 to pivot counter clockwise, as viewed in FIG. 15, to effect partial return movement of the

arms

99 and 100 to retract the fingers 105 from within the connector sleeves 2.

It is to be noted that the lever arm 113 has a shoulder 149 formed by an extension 150 extending from the straight portion 122. The shoulder 149 is engageable with the push rod 117 on downward movement of the slide 13 to urge the lever arm 113 to pivot back to its normal position and to align the slot 136 with the latch 137. The end of the latch 137 which is in engagement with the spring loaded pin 141 has an inclined portion which urges the latch to return to a latch position upon completion of the downward stroke of the slide 13 so that the latch 137 is received within the slot 136 to retain the lever arm 113 in its latched position with the cam portions in operative position extending through the

plate

14 and 15. An adjustable stop 151 is secured to the lever arm 113 and helps align the latch 137 and slot 136.

The apparatus 1 includes means for trimming the wires 8 to even the ends thereof and to insure the proper location of the wire ends within the connector sleeve 2. In the illustrated structure, cutters are secured to the mounting block 101 and positioned adjacent to

respective loading arms

99 and 100. Preferably the cutter adjacent to each loading arm is comprised of a first shearing plate 153 and a first plate member 154 with a spacing plate member 155 therebetween all secured to the mounting block 101 with the shearing plate 153 being adjacent to the respective loading head 104 (FIGS. 12 and 13). A movable shearing plate 156 is movably mounted between the shearing plate 153 and the plate 154 within a recess 157 in the spacer plate 155. Preferably, the shearing plate 156 is pivotally mounted as by having a pivot pin 158 extending therethrough and through the

plates

153, 154 and 155. The shearing plate 156 shown is in sliding engagement with the shearing plate 153. The shearing plate 153, the plate 154 and the shearing plate 156 each have a pair of

wire receiving slots

159, 160 and 161 respectively which are in alignment with a respective pair of fingers 105 for receiving a respective wire 8 therein whereby movement of the shearing plate 156 relative to the shearing plate 153 cuts the wires therein so as to trim the ends thereof evenly.

Drive means operably connect the shearing plates 156 to the slide member 13 so as to effect movement thereof in response to movement of the slide member 13. As illustrated a shaft 162 is rotatably mounted in the mounting block 101 having ends thereof each'positioned adjacent to the respective loading head 104. A cam member 163 with a cam slot 164 is secured to each end of the shaft 162 and is adapted to receive a depending ear portion 165 of the shearing plate 156 within a respective slot 164. It is to be noted that the slots 164 have two side edge portions engaging both side edges of the ears 165 whereby rotation of the shaft 162 in either direction will effect pivoting movement of the shearing plates 156. As shown, a lever arm 167 is secured to the shaft 162 and has a spring 168 connected thereto and to a bracket member 169 which is fixed to the support 12. The spring 168 biases the lever arm 167 to the position in which the

slots

159, 160 and 161 are in alignment. An arm 170 is pivotally mounted on the bracket member 169 and has one end thereof in engagement with a depending flange portion 171 of the adjacent cam' member 163. The lower disposed end of the arm 170 is positioned adjacent to the bracket 119 and is in engagement with a push rod 172 which is reciprocably mounted in a guide bore 173 through the bracket 1 19. One end of the push rod 172 is engageable with the lower end of the arm 170 and the opposite end of the push rod preferably has a roller bearing member 174 mounted thereon. A lever arm 176 is pivotally mounted on the slide member 13 and is similar in construction and operation to the lever arm 113 having a cam surface 177 similar to the cam surface 121 with two

straight portions

178 and 179 and an inclined por: tion 180 therebetween. I

Upward movement of the slide member 13 effects axial movement of the push rod 172 which in turn cf fects rotation of the shaft 162 and pivotal movement of the shearing plate 156. The spring 168 helps maintain the push rod 172 in'eng agement with the cam surface 177. The lower disposed end of the lever arm 176 has a slot 181 which is adapted to receive a portion 'of the latch 137 therein to maintain the lever arm in nonpivoting relation until the latch 137 is moved by engagement between the

inclined surfaces

142 and 144 to effect release of the lever arm 176 similar to release of the lever arm 1 13. It is to be noted that the straight portion 122 of the lever arm 113 is longer than the straight portion 178 of the lever arm 176 whereby the wires 8 are cut before the loading arms move out of their normal position for loading the wires 8. Also, the lever arm 176 has a shoulder 182 formed by an extension 183 similar in construction and operation to the shoulder 149 and extension 150. The lever arm 176 is provided with an adjustable stop 184 so that the slot 181 can be aligned accurately with the latch 137.

The apparatus 1 preferably is provided with ejector means 9 which are operable to eject the crimped connector sleeves 2 and the wires 8 therein after the final crimp has been applied to the connector sleeves 2. 1n the illustrated structure, a pair of ejector arms 186 are positioned within

slots

187 and 188 in the support member 12 adjacent to opposite ends of the connector sleeves 2 when same are between the crimping jaws 73. Each of the ejector arms is provided with two generally U-shaped upwardly facing openings or notches 189 which receive the wires 8 therein. The ejector arms 186 are each secured to a shaft 190 whereby rotation of the shaft 190 moves the ejector arms from their normal position within the

slots

187 and 188 upwardly and away from the loading

arms

99 and 100 to eject the crimped connector sleeves with the respective wires therein from the apparatus 1. The shaft 190 is operably connected to the slide 13 which provides motive power thereto. As illustrated, the shaft 190 has a sprocket 191 thereon with a chain 192 in engagement therewith. The chain 192 has one end thereof secured to a sliding catch 194 which is movably mounted on the support member 12 and the plate 14 has a catch or pawl 195 pivotally mounted thereon which is adapted to pivot on the upstroke of the slide 13 when same engages the slide catch 194 preventing any movement of the shaft 190 on the upstroke of the slide 13.

At a predetermined position on the downstroke of the slide 13 the catch 195 engages a shoulder 196 causing the slide catch 194 to move downwardly thereby causing the shaft 190 to rotate and move the ejector arms 186 and at a second predetermined position on the downstroke of the slide 13 a pin 198 secured to the catch 195 engages a cam surface 199 which releases the catch 195 from engagement with the shoulder 196. Releasing of the catch 195 on the downstroke permits the shaft 190 to rotate in a reverse direction allowing the ejector arms 186 to return to their normal position under the influence of a biasing spring 201 which has one end secured to a pulley 202 and is partially wrapped therearound with the pulley being secured to the shaft 190. The slide catch 194 has a second shoulder 204 adjacent the upper end thereof and is engageable with a pawl 205 which is pivotally mounted on a mounting block 206, which in turn is secured to the support member 12. The other end of the spring 201 is suitably secured to the pawl 205 and biases same to move in a counter-clockwise direction about a pivotal mounting of the pawl 205.

At ia predetermined position on the downstroke of the slide catch 194, the pawl 205 engages the shoulder 204 before the catch 195 is released by the engagement between the pin 198 and the cam surface 199. The engagement between the pawl 205 and the shoulder 204 prevents upward movement of the slide catch 194. A guide member 207 is secured to the slide 13 and is movable therewith and has a rod 208 extending through a guide bore,(not shown) with one end of the rod 208 being secured to the pawl 205. A stop member 209 is secured to the free end of the rod 208 and at a predetermined position on the downstroke of the slide 13 the stop member 209 engages the guide member 207 so as to effect clockwise rotation of the pawl 205 to release the slide catch 194 for upward movement thereof allowing the ejector arms 186 to return to their normal position within the

slots

187 and 188. Reverse rotation is effected by the biasing spring 201 as described above. A second stop member 211 is secured to the rod 208 and is operable to engage a stop pin 212 which is secured to the mounting block 206 to limit the counter-clockwise rotation of the pawl 205.

The apparatus 1 includes cutting means which are operable to separate an end connector sleeve 2 from each of the elongate chains 30 after same are fed into the crimping means 6 with the cutting means being operably connected to the slide 13 to effect and time operation thereof. In the illustrated structure the cutting means includes a pair of

knives

214 and 215 movably mounted on the support member 12 and positioned between the ends of the

channel

28 and 29 and the crimping means 6. The knife 215 is secured to a member 216 which extends through an opening 217 through the support member 12 and is partially supported thereby. The ltember 216 is slideably mounted on a bracket 218, which is secured to the support member 12 and has a shoulder member 219 thereon engageable with an eccentric cam member 220 which is secured to the shaft 190. A spring 221 is secured to the member 216 and bracket 218 biasing the knife 215 to a position retracted and away from the respective chain 30 and maintains the shoulder member 219 in engagement with the cam member. The knife 214 is movably mounted on the bracket 218 and has a shoulder forming member 222 engageable with an eccentric cam member 223 secured to the shaft 190. A spring 224 is connected to the knife member 214 and to an arm 225 secured to the bracket 218. The spring 224 biases the knife member 214 to a position retracted and away from the respective chain 30, and maintains the shoulder member 222 in engagement with the cam 223. Reverse rotation of the shaft 190 by bias of spring 201 effects movement of the

knife

214 and 215 quickly toward one another to cut the end connector sleeves 2 from the remainder of the chains 30. The cutting is accomplished at the very last of the downstroke of the slide 13 when the pawl 205 releases the ejecting arms 186 to return to their normal position.

To keep count of the number of wires spliced, the apparatus 1 is provided with a resettable counter 227 which is mounted on the support member 12 and counts each stroke of the ram 19. The counter 227 is operatively connected to either the ram 19 or the slide 13 by suitable means. The apparatus 1 is enclosed in a housing 229 for preventing accidental contact with moving parts of the apparatus 1 for operator safety. The housing 229 can be of any suitable structure and preferably is easily removable from the apparatus 1 and is secured thereto by suitable fasteners 230. It is to be noted that the only moving parts of the apparatus 1 to be exposed are the loading

arms

99 and 100 and the ejector arms 186. The apparatus 1 is mounted on a carriage 232which in the illustrated structure is comprised of two elongate rod members 233 secured to and eX- tending between two upright structural members 234 for supporting the rods 233. The rods 233 are vertically spaced apart and have slideably mounted thereon brackets 234 which are secured to the housing 229. The apparatus 1 is movable horizontally along the rods 233 and a lock or stop 236 is provided to retain the apparatus l in the desired position for use. Movement of the apparatus 1 permits positioning of the connector sleeves 2 along the length of the splice between the

cables

3 and 4 so as to reduce the size of the finished splice.

In the illustrated structure the connector sleeves 2 are in end to end relation in the form of an elongate chain. The connector sleeves 2 have a bottom wall 239 with upstanding side walls 240 in spaced apart relation with a conductive member 241 secured therein. Insulation penetrating teeth 242 extend inwardly from each of the side walls 240 and when the connector sleeve 2 is crimped as shown in FIG. 3 the teeth 242 penetrate the insulation and effect electrical contact with the conductor in the wire 8. Adjacent connector sleeves 2 in the chain 30 are connected by a tab 243 preferably integral with and extending between the adjacent connector sleeves and which is cut to separate the connector sleeves. It is to be noted, as best seen in FIG. 3. the connector sleeve is crimped onto two wires 8 with the wires 8 therein being in generally parallel and end to end relation.

The present invention is more fully understood by a description of the operation thereof. When the slide 13 is at the bottom of the downstroke and connector sleeves 2 are in the wire receiving position. the apparatus 1 is ready for loading wires 8 into the loading

arms

99 and 100 wherein the fingers 105 securely hold the wires 8 in place. The operator of the apparatus 1 selects two wires from each of the

cables

3 and 4 matching one wire from each cable with a corresponding wire from the other cable by the color coding on the insulation thereof. It is to be noted that wire guides 245 are provided and preferably are secured to the mounting block 101 with the wire guides each having two wire receiving slots 246 therein with each being in alignment with the respective pair of fingers 105. The wire guides 245 facilitate loading of the wires 8 within the respective fingers 105. Pins 247 are secured to the apparatus 1 and extend generally upwardly from the upper disposed edge thereof and are adapted to help separate the wires to be spliced from the remainder of the wires within the

cables

3 and 4.

The selected wires 8 are inserted between their respective fingers 105 with a portion of the wires extending outwardly from the plate 154. One pair of wires to be spliced is placed within the respective fingers 105 nearest the support member 12 and the other pair of wires being placed in the respective fingers furthest from the support member 12. The connector sleeves 2 are held in the wire receiving position before actuation of the ram 19 by the gripping pins 89. After the wires are inserted between the respective fingers 105, the operator actuates the ram 19 starting the upstroke of the slide 13. At a predetermined position on the upstroke, the lever arm 176 effects and times movement of the plate 156 relative to the plate 153 and trims the ends of the wires 8. Upon further upward movement of the slide 13, the lever arm 113 effects and times movement of the

loading arms

99 and 100 whereby same simultaneously move to a wire depositing position. as illustrated in FIG. 15, with the fingers 105 holding and controlling the wires 8 within the respective connector sleeves 2. With the

arms

99 and 100 in the wire depositing position, the slide 13 continues upward movement whereby the cams 81 move the crimping jaws 73 to ward the anvil 76 to partially crimp the connector sleeves 2. Toward the completion ofthe upstroke of the slide 13, the latch 137 is moved by engagement between the

surfaces

142 and 144 whereby the

lever arms

113 and 176 move to an inactive position with movement of the lever arm 113 allowing the loading

arms

99 and 100 to begin retraction from the connector sleeves 2 and movement of the lever arm 176 allowing the shear plates 156 to return to their normal position. Still during the upstroke of the slide 13 and after the

loading arms

99 and 100 have begun retraction. the cams 81 effect and time final crimping of the connector sleeves 2 onto the wires 8.

The slide 13 completes the upstroke and then begins to move on the downstroke. At a predetermined position on the downstroke, the jaws 73 retract from crimping engagement with and release the connector sleeves 2. Upon further downward movement of the slide 13, at a predetermined position, the catch 195 engages the shoulder 196 to effect and time movement of the ejector arms 186 to eject the crimped connector sleeves 2 and wires 8. After the ejector arms 186 have ejected the connector sleeves 2 and wires 8, they are retained in the eject position by engagement of the pawl 205 and shoulder 204. During ejection, downward movement of the slide 13 effects and times upward movement of the housing 27 through the lift member 57 engaging the reciprocal cam means 62. After the housing 27 is raised, the arm 36 begins feeding movement through the engagement of the roller 39 and end 38 to feed the leading connector sleeves 2 into the wire receiving position between the crimping jaws 73 and anvil 76. With the feed housing in the up position and the connector sleeves being positioned in the wire receiving position, further downward movement of the slide 13 releases the pawl 205 from engagement with the shoulder 204 allowing the shaft to reverse rotate under bias of the spring 201 with the ejector arms 186 returning to their normal position and the

cutters

214 and 215 being moved as described above to separate the leading connector sleeves from the chains 30. Toward completion of the downstroke of the slide 13, and after separating the connector sleeves, the reciprocal cam means 62 moves out of engagement with the lift member 57 allowing the feed housing to return to its down position where engagement between the fingers 47 and cams 66 retracts the detent 55 from the slots 42. With the slide 13 in its down position the apparatus is ready to splice four more wires. The arm 36 returns to its counterclockwise position during upward movement of the slide 13. It is to be noted that at a predetermined position on the downstroke of the slide 13 near the completion thereof and after the connector sleeves 2 are in the wire receiving positions, the springs 94 are compressed urging the gripping pins 89 to extend through the jaws 73 and hold the connector sleeves 2 in their wire receiving position. Splicing continues until all pairs of wires are spliced.

It is to be understood that while I have illustrated and described certain forms of my invention, it is not to be limited to the specific form or arrangement of parts herein described and shown.
