This invention is an improvement over that shown in my co-pending application Serial No. 193,702, filed May 23, 1927 and comprises many novel features not included in that application.

Referring to the drawings by reference characters I have indicated my improved stamping device generally at and although it is adapted for other purposes I have shown it in conjunction with a box liddingmachine, only the continuous conveyor table 11 of the lidding machine being shown.

My improved stamping device 10 is so constructed that it may be used between a lidding machineand a strapping machine without interfering with the actuation of either or being in the way of the operator of either machine. But it will be understood that my machine may be used in conjunction with either machine or may be used wherever desired.

As shown in the accompanying drawings my improved stamping device 10 comprises a base 12 having a standard 13 thereon in which a shaft 14 isrmounted for rotation. The shaft 14 terminates in a head 15 to which it is secured and which is adapted to move with the shaft.

Within the head 15 I mount for rotary movement a sleeve 16 to one end of which is secured a type carrying roll 17 and to the opposite end of which is secured a-spur gear Mounted for rotary movement within the sleeve 16 I provide another sleeve 19 to one end of which is secured another type carrying roll 20 and to the opposite-end of Within the which is secured a spur gear 21. sleeve 19 I provide a rotatable shaft 22 to one end of which is secured a third type carrying roll 23 and to the other end of which is secured a spur gear 24.

As shown in the accompanying drawings the type carrying drums 17, 20 and 23 each of type bars 17 20* and 23 respectively, each of which may include different indicia of various characters. The type bars 17 may bars 23 the variety of the goods in the container which is stamped.

The gears 18, 21 and 24 are adapted to be rotated by racks'25, 26, and 27 respectively which are supported in a' bearing 29 integral v withan annular member 30 which is secured to the standard 13 (see Fig. 2).

As shown in" Figs. 6, 7, 18, 21 and 24 each include a housing 31 in which is mounted 'a clock' spring 32 for re 4 Y V 7 indicate the packers nu n her, the type bars 20 the grade and the type 8 and 9 the gears turning the gears to their initial positions. One end of each spring 32 is secured to the gear as at 33 and the opposite end is anchored to the shank of a screw 34 which is supported by an arm 35 of a bracket 36 which is secured in any desired manner to the head 15. A stop 36 is provided upon the face of each of the housings 31. Each stop is adapted to abut an arm 35 when one of the gears 18, 21 or 24 is in its initial position.

For retaining the gears 18, 21 and 24 in the position to which they are moved by their respective racks I provide pawls 37 each of Whichis mounted for independent movement on a shaft 38 mounted on the bracket 36. The pawls 37 are shown as adapted to be yieldably urged into engagement withthe gearsby springs 39 secured to the bracket 36. Each of the pawls 37 include a. downwardly extending finger 4Q which isadapted to engage an upwardly extending portion 41 of a trigger 42. This trigger 42 is shown as pivoted ona shaft 43 supported by the bracket 36 and includes 'a downwardly extending portion 44.

The portion 44 is adapted to abut'a trip 45 and causes the trigger 42 to moveabout its pivot 43 and move all of the pawls 37 out of engagement with their respective gears from the. pawl 37 as clearly shown in Fig. 8

and will not actuate the pawls 37. V The racks 2'5, 26 and 27 are provided, with rods 47, 48 and 49 which extend below the bearing 29 and are slackly-connected to. rocker arms 50, 51,'and 52 respectively as atv 53 (see Figs. 2 and 10). Theserocker arms 50, 51 and 52 are each pivoted as at 54 to a support indicated generally at 55 andare slackly connected as at 56 at their opposite ends to other rocker arms 57, 58 and 59, which w are pivoted as at '60 to the support 55. (See Figs. 3 and 10.) I Each of the rocker-arms 57, 58'and 59 is slacklyfconnected as at 61 to levers 62, 63 and 64' which are pivoted as at 65 and include arms 66,67 and 68.. The

rocker arms 50, 51 and 52 areadapted to be returned to their initial positions against a stop69 springs 7 0 which are anchored at' one end to the support 55 as shown in Fig. 10.,

For actuating the various rocker arms to' move the racks 25, 26 and 27', and cause the gears"18,.21 and 24 torotate and thereby rotate the type drums 17 20 and23 to various positions I provide upon the support a selective device indicated generally at72 in Figs- 3,10, 11 and 12. This selective device includes groups of keys 73, 74 and 75 which correspond to the type carrying drums 23, 20 and 17 respectively. Each of the keys in the group 73 corresponds to the indicia 23 upon the'drum 23, the keys in the-group 74 each corresponds to the indicia 20 on the type drum 20 and each of the keys in group 75 corresponds to the indicia matter 19 on the drum 17. As a rule there will be more keys provided in each of the groups than there is indicia matter on the type drums so asto take care of the maximum amount of indicia matter which may later be placed upon the indicia drums.

The selective device 72 includes a housing 76 having a top 77 secured thereto and made of an insulated material shown in Fig. 11. In the accompanying drawings I have shown the groups of keys 75 as including eight rows of keys 78 arranged eight in a row, thus totalling sixty-four in all, and the groups 73 and 7 4 each having ei ht rows of keys 78 arranged two in a row. Each of the keys 78 is secured to a stem 79 which is arranged in the top 77 for reciprocatable movement and includes a semispherical knob 79 at its lower. end. Each of the knobs 79 of each key 78 in a single row is adapted to contact with a lever 80 which is pivoted to the housing at 80. The levers 80 are resiliently held against the knobs 7 9' by coiled springs 80 and are provided on their under sides with rollers 81. The rollers 81 on each of the levers 80 are adapted to engage transverse bars 82 which are provided adjacent each end with a pair of rollers 82' which are adapted to actuate in gnideways The transverse bars 82 are adapted to be resiliently supported by coiled springs 84 and have secured thereto a plunger 85. The plungers 85 are positioned for reciprocatable movement in bearings 86 and are provided at their lower ends with rollers 87. The roller 87 of plunger 85 of the key group 75 is adapted to contact with the arm 68 of the lever 64, and the roller 87 of the plunger 85 of the key group 741- is adapted to contact with the arm 67 of the lever 63, and the roller 87 of the plunger 85 of the key group 73 is adapted to contact with the arm 66 of the'lever 62.

As shown. the distance from the free end of each of the levers 80 to the pivot 80 is different so that the members 79 of each key associated with a single lever 80 contacts with the lever 80 at a difi'erent distance from the pivot 80. Thus it will be seen that full movement of no two keys engaginga single lever will move the lever the same distance and that no two levers in a single group will move thesame distance when fully actuated.

The keys in the *roup 73 may each indicate a different variety of goods, the keys in the group 74 may each indicate a different grade and the keys in the group 75 may each indicate a different packers number.

From the foregoing description it will be seen that to position the type bars on the type carrying drums 17, 20 and 23 it is only necessary 'for the operator to depress one of the keys in each of the groups 73, 74 and 75 which will, through the medium of the arms 66, 67 and 68 and the various associated levers cause the rods 47, 48 and 4-9 of the racks 25, 26 and 27 to move and thus move the racks and cause the gears 18, 21 and 2% to rotate the type drums 17. 20 and 23 to position the selected type in a stamping position. The levers 80, etc., will be of such length that depression of each operating key will cause a certain desired type to be turned to operative position.

Positioned beneath each of the keys 78 of the selective device 72 I provide a pair of electric contacts 90 which are adapted to be bridged by a Contact ring 91 on the under side of the keys 78. As shown in the wiring diagram in Fig. 13 one of the contacts 90 is connected through a wire 92 and a wire 93 to a source of electrical energy shown as a battery 9 1. The other contacts 90 are connected through a wire 95 to the trip actuating solenoid winding 96 of counter mechanisms 97. The counters 97 may be of any approved standard type and will usually be located a considerable distance from the selective device 72, preferably in the ofiice of the packing house in which my device is used. From each coil 96 a wire 98 connects through a wire 99 with the battery 94. I preferably employ a counter for each key so that when one of the keys 78 is depressed to position a certain type bar the contact ring 91 will bridge the contacts 90 and cause the counter mechanism 97 associated with that particular key to actuate and register.

The type rolls 17 20 and 23 are all preferably constructed alike so I will only describe the roll 17 which is shown in detail in Fig. 14. This type roll 17 is adapted to support a plurality of type bars 17 which fit in the dovetailed grooves 100 of the type roll and are retained in the grooves by a retaining ring 101. The retaining ring 101 is supported by a plurality of bolts 102 on which it is movable. 7 The bolts 102 have shoulders or washers 102 which engage the end of the roll and prevent the bolt from being drawn to engage the ring. A plain belt 103 is provided for clamping the retainingring 101 in a fixed position to the roll 17. The retaining ring 101 is notched as at 104 to provide an aperture throughwhich the type bars 17 may be inserted orremoved from the grooves 100.

VVhenit is desired to insert or remove a type bar 17 from the type roll the belt 103 is loosened and the retaining ring moved so that the notch 104 aligns with the groove 100 in elongated slot 108 which the type bar is to be inserted or re. moved from. After the type bar has been removedor inserted the ring 101 is again moved to its normal position as-shown in Fig. 14. The type bar which would normally occupy the groove which. is in a stampingv position when the type roll is in a normal position is preferably omitted as shown in Fig. 14.

The type bars 17 each preferably rest on the type bars the life of the type thereupon- "will be greatly prolonged and a better impression will be made. 7 For inking the type bars after they have been moved to a stamping position I provide an inking roller 106 (see Figs. 4 and 5) which may be of any desired size. The inking roller may be made of any desired material and is shown as mounted on .a plunger rod 107 which.- is reciprocatably mounted in a slide bearing 108 integral with the head 15. For applying ink to the roller 106 I have shown an ink carrying pad 109 mounted on a bracket 110 integral with the head 15.

,For reciprocating the plunger rod: 107 I us have shown a lever 111' pivotally connected thereto adjacent the end opposite the inking roller 106. This lever 111 which comprises two telescopic sections is shown as pivotally supportedby a bracket 112 rigid with the -head15. The lever 111 is adapted to be moved by a lever 113 to which it is pivotally connected by a link 114. The lever 113 is pivoted intermediate its length to an arm 112 on the bracket 112 and is provided at its .free end with a roller 115 which projects downwardly and 18 positioned in a cam groove 116 formed in the annular member (see Fig. 16). The slide bearing 108 is provided for a part of its length with an in which the lever 111 moves when actuating the plunger rod 107.

type bars of the type drums but rests on the the stamping operation.

, hen the head 15 and the type rolls are in anormal or inoperative position as shown in Fig. 3 the plunger rod 107 is retracted and the mking roller does not contact with the hiking pad 109. As the head 15 and the type d 1111118 move towards a stamping position as shown in Fig. 4, the roller 115 is moved in a J branch 117 of-the cam groove 116 and through the 'mediumof .lever111, link 114 and lever 113 causes the plunger rod'107 to advance and move the inking roller 10.6 over the face of the type bars which are to perform As clearly shown in Fig. 16 the cam grooveis of such a shape as to cause the plunger rod-and the inking roller 106-to be fully retracted again before the type drum has .reachedia, stamping position (S Fien es he ei J as? t t drums return from a stamping position to; "the normal or inoperative head 15 and the type drums I provide an arm 120 (see Figs. 1, 4, 17 etc.) which is secured to the shaft 14 and is arranged in an enlarged boss 121 on the standard 13. The arm 120 is pivotally secured to one end of a link 122. The other end of the link is to a rotatable disk 124. I

I prefer to pivot the arm 120 as at 123 to the link 122 in a resilient manner as shown in detail in Fig. 17 so that when the type drums strike the article to print thereupon v the shock imparted to the whole device will not be destructive. As shown in Fig. 17 the link 122 is provided with a head 125 in which is provided an 127 through which the shank of the pivot 123 passes. At the opposite end of the aperture 126 I provide a slide 128 which includes a boss 129. A coiled spring 130is positioned in the aperture 126 between the" block 127 and pivotally secured elongated aperture 126. Positioned in the aperture 126 I provide a block the slide 129. To adjust the tension of the I spring 130 I provide a set screw 131 in the end of the head 125 which contacts with the slide 123 and is adapted to be retainedin a fixed position by a lock nut- 132'. Thus it will be seen that when the arm 120 comes to a stop when the type drums strike an article the link 122 may continue to move against the action of the spring 130 for a short distance.

The disk 124 is adapted to be rotated from 7 gears through the medium of a reduction transmission indicated at 134. The transmission 134 may include any arrangement of gearsdesirable and is shown as adapted to be operated by, a shaft 135 which is adapted to be rotated by a clutch 136, The clutch 136 includes a clutch spool 137 and is shown as adapted to be rotated by a shaft 138 supported in a bearing 7 tical shafts 145 and project from one side of the conveyor mechanism 11 into the path of the box or receptacle upon which it is desired to stamp. The shafts 145 are journaled in bearings 146 secured to the conveyor mechanism and in bearings 147 secured to the fi'oorQ Secured to the shafts 145 adjacent the bear I 139 on the base 12. The shaft 138 is shown as adapted to be rotated through which are ings 147 I provide arms 148 and 149, each of provided with an elongated aperture 150. The arms 148 and 149 extend from the shafts 145 in opposite directions to each other so that they will not be moved in the same direction. f j

Supported in bearings 151 and positioned in the apertures 150 of the arms 148 and 149 I provide a rod 152 which is pivotally connected at one end to an arm 153 which is pivotally mounted on a bearing 154 as at 155. On the rod 152 adjacent each of the arms 148 and 149 I provide an enlarged collar 156 against which the arms 148 and 149 are adapted to abut to move the rod 152. For retaining the rod 152 in a normal position I provide a coiled spring 157 which abuts one of the rod bearings 151 and abut-s a collar 157 secured to the rod'152 as clearly shown in Fig. 18.

WVhe'n a box enters the lidding machine in the direction indicated by the arrow in Fig. 3 it strikes and rocks the arm 144 and causes the arm 149 to move away from the adjacent collar 156 on the rod 152 as shown in Fig. 3, and does not move the rod 152. As the box continues to travel and fully enters the lidding machine it trips and rocks the arm 143 and causes it to move the arm 148 which in turn abuts the adjacent collar 156 of the rod 152 and causes the rod 152' to move, thereby ,moving the arm 153.

lVhen a box enters the lidding machine in a direction opposite to that indicated by the arrow in Fig. 3 the action is just the opposite to that described, that is, the box strikes the arm 143 and causes the arm 148 to move away from the adjacent collar 156 and does not move the rod 152, but when the box strikes the arm 144 it moves and causes the arm 149 to abut the adjacent collar 156 on the rod 152 and moves the rod 152 which in'tur n moves the arm 153 in the same direction as when it is caused to move by the arm 143.

The arm 153 is slidably connected as at 158 to a rod 159 which is shown as supported in a bearing 160 and hinged intermediate its length as at 161. For restricting the hori zontal movement of the rod 159 to one direction I provide a stop 160 which is integral with the bearing 160 and clearly shown in Fig. 2. The rod 159 is pivotally connected to a rocker arm 162 which is pivoted intermediate its length as at 163 and engages the clutch spool 137 asat 164. Thus when the arm 153 moves the rod 159 in the direction indicated by the arrow in Fig. 3 the spool 137 will be moved to cause the clutch 136 to engage and cause the stamping mechanism to be actuated.

rocker arm to move the clutch spool 1'37 out of engagement with the clutch 136 to discontinue the actuation of the stamping device.

The rocker arm 162 is provided with another upwardly extending arm 168 (see Fig. 2) which is connected by a rod 169 to an actuating lever 170 of a brake mechanism 171 which is adapted to operateon the end of the transmission shaft 135. Thus when the clutch spool 137 is disengaged from the clutch 136 the brake 171 is automatically applied to the transmission shaft 135 to immediately stop the actuation of the stamping device.

As the box is still in the lidding machine after the stamping mechanism has actuated and the arm 153 retains its clutch setting position, it is necessary to provide means to allow the rod 159 to return to its normal position when the lug 166 causes the clutch spool to move out of engagement with the clutch. To allow for this movement I prefer to construct the slack connection 158 of the arm 153 and the rod 159 as shown in detail in Figs. 19, 20 and 21-. The end of the rod 159 is flattened as at 173 and provided with an elongated aperture 174, the outer end of which is provided with a notch 175. The arm 153 is provided with a bolt 176, the shank 177 of which is adapted to actuate in the elongated. aperture 174 and the notch 17 5.

For normally urging the end of the rod 159 towards the arm 153 to retain the shank 177 in the notch 175 I provide a coiled spring 178 having one end attached to a lip 179 of the rod and having the opposite end anchored to the arm 153.

When the arm 153 is moved to actuate the clutch mechanism the shank 177 of the bolt 176 moves the rod 159 until the arc travel or" the arm causes the shank to move out of the notch 175 into the elongated aperture 174 as shown in Fig. 20.

When the lug 166 of the disk 124 causes the clutch mechanism to be disengaged the rocker arm 162 moves the rod in a direction opposite to that indicated by the arrow in Fig. 3, and as the shank 177 of the bolt 176 of the arm 153 is positioned in the elongated aperture 174 the rod 159 moves independent of the arm 153 which cannot return to its normal position until after the box has been removed from the lidding machine (see Fig. 21

WVhen the box is removed from the lidding machine the arms 143 and 144 return to their normal positions and move the arm 153 back to its normal position so that the shank 17 7 of the bolt 176 is again positioned in the .notch 175 whereupon the device is again in an initial position and set to be actuated by anotherv box entering the lidding machine.

In Figs. 22 to 26 inclusive I have shown a modified means. for positioning the type bars ina printingposition. In this modified means the selective mechanism is shown as 71 on the opposite side of the conveyor to the stamping device, butit willbe understood that with very little alteration it may be located on the same side as the stamping mechanism When desired.

This modified selective device as shown comprises three hand wheels 180, 181 and 182 Which correspond to the type drums 17, 20 and 23 respectively. Each of the hand wheels 180, 181 and 182 are adapted to be connected to the gears 18, 21 and 24 in exactly the same manner, therefore but one of the connections between the hand wheels and the gears will be described. I

As shown in the accompanying drawings the hand wheel 182 is mounted to rotate a shaft 184 which is mounted in a bearing 185 secured to the side of the conveyor mechanism 11. bevel gear 186 is secured to the shaft 184 and meshes with another bevel gear 187 on one end of a shaft 188 which is position'ed in a bearing 189 integral with the bearing 185.

cured to the opposite end of the shaft 188' Another bevel gear 190 is seand is adapted to mesh with a bevel gear 191 secured to oneend of a shaft 192 which is supported in bearings 193 secured to the conveyor frame. Another bevel gear 194 is secured to the opposite end of the shaft 192 and is adapted to mesh with a bevel gear 195 secured to a shaft 196 and is adapted to actuate the type drum 17. I As shown in Fig. 24 the bevel gear-195 which is adapted to actuate the type drum 20 is secured to a sleeve 197 which surrounds the shaft 196 and the bevel gear 195 which is adapted to actuate the type drum 23 is secured to a sleeve'198 which surrounds the sleeve 197.- I The shaft 196 and the sleeves 197 and 198 are shown as supported in bearings 199 secured to the conveyorframei A. spur gear 200 is secured to the opposite end of the shaft 196 and spur gears 201 and 202 are secured to the opposite ends of the "sleeves 197 and 198 respectively.

VVhen'the modified selective device is used the racks 25, 26 and 27 previously described are replaced by racks 203, 204, and 205, which in addition to being'positioned in the'bearing 29 are positioned adjacent their lower ends in a bearing 206 which may be secured to the standard 13 in any desired manner.

'The racks 203, 204, and 205 in addition to having gear teeth adjacent their upper ends similar to the racks 25, 26 and 27, are provided with similar gear teeth adjacent their I lower ends as indicated at 207.

I The bearing 206 is provided with a plurality of apertures as indicated at 208 through which the gears200, 201 and 202 are adapted to extend to engage the racks 203, 204 and 205 respectively so that when the hand wheels 180, 181 and 182 are operated the gears 200,

201 and 202-will move the racks 203, 204

206 as shown in Fig. 22

previously described.

pins 209 when in an initial position are adapt ed to abut a stop 212 formed in the grooves 210 so that upon rotation of the hand wheels in one direction the pins 209 will rotate the shafts 184 but will not rotate the shafts when they are returned to their initial position.

For returning the hand wheels, to their in itial positions I provide clock springs 213 positioned in housings 214 secured to the bearings 185. are secured to the hand wheels as at 215 and their opposite ends are anchored to the hous ings 214 as at 216.

, Secured to the housmgs 214 I provide dials 217, upon which isprovided indicia matter One end of the springs 213 as indicated at 218 corresponding to the in- 'dicia upon the type bars of the type drums 17, 20, and 23, with which the corresponding hand wheel is connected. Each of the hand wheels is preferably provided with apointer 219 and stops 220 are provided'on the dials 217 for the pointers 219 to abutwhen .the hand wheels are in their initial posi- 'tion.

. For returningthe racks 203, 204 and 205 to their initial positionafter the head 15 has started towards a stamping position, I provide coiled springs 221 anchored at one end to a bracket 222 on thestandard 13 and se-" i cured at their oppositeends to an arm 223 provided on each ofthe racks. The arms 223 I also act as stops to limit the downward movement of the racksby" abutting the bearing From the foregoing description it willbe apparent that when the hand wheels are releasedafter being moved vtoposition a oer tam type bar they will immediately return to their initial positions and that the racks will return to their initial positions as soon as the gears 18,21 and 24 move out of engagement with them as the head 15 moves toward a stamping position. Thus the type positioning mechanism is automaticallyreset to again be actuated to position the type.

The type drums 17, 20 and 23 will be returned totheir initial positions when the pawls 37 are moved out of engagement with the gears 18, 21, and 24 by the trigger 42 as Having thus described my invention, I claim: 9 7
