My collar decapper applying machine is shown herein as an example of a complete machine to receive in open collar form, adapt to bottle fit, and apply to bottle in finished form my 'decapping collarwith my desirable adapting mechanism incorporated therein as the'finaI- forming means. This machine is made mainly of suitable cast' or wrought metal and design'ed'to'st'and beside a chain conveyorwhich carries bottles to be filled and crowned. A base 1 supports a main standard 2 which may be substantially of I'-beam shape, and forward of same on the base is erected a tubular lesser standard 3 that is attached to the main standard at its upper end by a bracket 4 extended from the said main standard. Slidably mounted upon" said tubular lesser standard 3 and adjustable vertically on same to suit the height of a bottle conveyor, by means of a slide collar and a set screw '5, is a bracket 6 which terminally embraces the chain conveyor 7 by 'the'upward extension of an end arm 8, adjustable by 'set screw 8A, which may act as a guide and back support-for the bottles travelling on' the chain conveyor. On bracket 6 opposite said e'n'd'arm Sis rotatably mounted'ajstar wheel 9 with its arms extending over the conveyors to intercept and engage a passing bottle and rotate 'as it moves'along, 'the'end aim' oo-operating to contactually center'the bottle in and between the embraeing arms of the star wheel 9 at' one'ppint of the rotation of same. The 'stem'o'f star'wheel 9 is mounted in bracket 6 and extendsthro'ugh'its bearing to mount on its lower end 'a bevel" gear wheel 10 which engages" a train of gears '11 inwhich 'isinclu'deda sprolcket'wlie'el1'2 from which a drive chain 13"e'xtends to'a source of motive power; Included" in said gear train 11 i 'a'hubmounted horiipnteilly"rotatinggear wheel "14 which'has squared central aperture through its axis of rotation. Said gear train' 1'1 terminates" adjacent lesser standard 3"in" the bracket 6 in a'fiat disk"wheel 15 having a transversive aperture oif center in its face whichengages a'pivot stud on the lower end of a driving bar 17 that extends upward therefrom to pivotally engage a vertically adjustable collar 16 which is slidably m'ounted onth'e shank 19 of the" decapper applying 'mechanism, "which shank 19 is tubula'r'faiid lslidesl verticallywithin the. tubular lesser standard}. The collar 18 held in position upon the shank19 by aiset' screw 20, which affords meansof adjusting the decappei' applying mechanism to suit the height of the bottles to which the decappers are to be applied, the eccentric movemehtof disk wheel 16, by means of barl17,"ra isin"g and low'ering'the' applier from :a'rid'finto steadying head contact with the bottles passing on conveyor 7. "The tubular shank 19 of the applying mechanism supports a head portion comprised of a bracket 21 which extends forwardly over the lower bracket 6 and carriesthe decapper a'pplying means. A hub-mounted n ver ear wheel 22 rotates horizontally on said bracket 21 and has squareicentral' aperture traversive of 'it s rotativ'e axisf'similarto that in gear wheel ;15 on bracket 61 whi'ch' is immediately below'said wheel .22 and in vertical axial alignment with same Geared at right angle to said wheel 22 and pivoted on bracket 21 is a vertically rotative gear wheel '23 of larger diameter which has aflat-face on which is pivoted, suitably oit center, one endiot a driving bar 24.7the otherend of which is pivoted to a horizontally reciprocative plungerZS, which moves to andjfro in a runway formed ingbracketZl by ' railbearings 26 and 27 as said gear, wheel. 23 rotates. 1 The forward ,end .28 of said plunger 25 is vertically hollow ed and spring'hingcd inthe center of said hollow are two horizontallyface plates 28A, preferably of hard rubber or the like, which are designed to resiliently contact the finished decapper collar, without defacing same, and push it upon a bottle neck when the bottle is intercepted by the intercepting mechanism below, until the laterally resilient decapping collar snaps into place on the bottle, as shown in Fig. 7. In the forwardly projected of bracket 21, at the end of the upper bearing rail 26 of applying plunger 25, is mounted invertedly a shanked cone, of hard rubber or the like, preferably, held in place by insertion of its shank in the bracket frame, that is designed to descend into the mouth of the bottle intercepted and steady it while the plunger 25 thrusts a collar decapper upon the bottle. Rearward of this steadying cone 29 a tubular shaft 30 extends upward through the bracket frame, forming an opening in and above the runway of the applying plunger to permit a fully formed decapper collar to drop in front of applier when the latter is in receded position, or temporarily rest upon the top of said applier if it is in forward position at the moment. Partly housed in said tubular shaft 38 is a metal slide post 31 down which the full formed decapper collars may embracingly slide within the said shaft 34 Vertically above and in alignment with the bottle intercepting mechanism, a bracket 32 extends from the main standard 2 and the upper end of said slide post 31 is attached to one side of a trap opening 33 in the lower side of said bracket 32. Adjacent the opening 33 and rearward of same there is mounted in the frame of bracket 32 for horizontal rotation a bevel gear wheel 34 that is in axial alignment with the square holed gear wheels 15 and 22 in the bottle intercepting and collar applying mechanisms below it on vertically adjustable bracket 6 and 21, which slide on and in the tubular lesser standard 3. Structurally integral with said gear wheel 34, which is hub mounted, is a square drive shaft 34A which extends downward vertically and passes slidably through the squared apertures in said lower gear wheels 15 and 22, being thus adapted to be turned by rotation of the lower gear wheel 15 by drive chain 13 and so transmit motion to the upper gear wheel 22 as it passes through same and finally rotate the uppermost wheel 34 in which it is secured terminally, as by pin 35. Mounted on the bracket 32 so as to mesh diagonally in said bevel gear wheel 34 is a transmission shaft 36 that has gear wheel terminals 37 and 38 which engage said wheel 34 and a bevel gear 39 on the front face of a vertically rotative disk wheel 40 pivoted above and rearwardly of said wheel 34, the said disk wheel 40 having a sprocket wheel 41 mounted on its reverse side. The said wheel 40 is pivoted centrally opposite a runway 42 formed thereat in bracket 32 by hearing rails 43 and 44. In said runway 42 is detachably mounted for reciprocative movement therein a compound shaping die comprised of various hinged and otherwise assembled co-operative parts, as 46, 47, 48, 50 and 51, in Figs. 1, 2, 3 and 4, and adapted to wrap a semi-formed decapping collar around a detachably mounted shaping arbor, as 53, by contact therewith, said shaping arbor being fixed in the path of the said shaping die by securing means, such as pin 54, and readily changeable for a difierently shaped arbor if desired, as by withdrawal and replacement of said pin 54. A forked driving bar 55 pivotally and detachably engages the rear body of the compound die 45, as by means of studs 56 at the fork ends engaging apertures in said body. The flat rearward end of said driving bar 55 is pivoted on the flat face of the sprocket wheel 41 on the reverse side of the disk wheel 40, siutably oil the center of same. The shaping die 45 thus moves to and from the arbor 53 as the disk wheel 40 rotates, and both die and arbor may be readily removed and replaced if others of different shape are desired to give final form to semi-formed decapping collars to fit the head and neck finish of different bottles. In the lower bearing 44 of the shaper runway 42 there is located, suitably distant from the arbor 53, the exit opening 33 for fully arcuated decapping collars. Immediately before the arbor 53 the runway floor forms a stop ledge 57 on which the semiformed decapper collar may drop to rest in front of arbor 53, through the overhead inlet opening 58 which is located above said stop ledge 57. On the shaper driving bar 55, beyond the radius of disk wheel 40, is pivoted the lower end of an agitator bar 59 the upper end of which is pivoted as at 60 on the shank of a feed drum 61 with a domed top that is vertically and rotatively movable in the funnel shaft 62 of funnel shaped upper feed hopper 63 that is adapted to receive semi-formed decapping collars and direct them into vertical grooves, as 64, of suitable formation to receive them in desired position, that are formed on and in the circumference of said feed drum 61, between same and the inner wall of said funnel shaft 62, the bottom of which grooves are closed except at one discharge port 65, by a collar 66 mounted upon said feed drum body below said grooves and supported as by pins 67, but held in the funnel shaft 62 as by screw head 68 in a wall slot in said shaft. This permits the collar 66 a limited vertical movement with the feed drum 61 out no rotative movement with it, as such lateral movement would block the discharge port 65. At suitable distance below said feed drum body, in the funnel shaft 62, a rack collar 69 is set within the shaft and secured to its wall, as by screws 70, thus forming an encircling rack around the lower ungrooved portion 71 of the drum body. Above this rack 69 on the drum body is freely pivoted a pawl 73 that is adapted to engage the rack 6'9 except when the feed drum ascends into hopper 63 to the limit of its vertical movement in the funnel shaft by action of the agitator bar 59. Then the pawl clears engagement with the rack and drops into rack teeth more vertically below its pivotal point. Thus when the feed drum descends by downward movement of the agitator bar 59 the new tooth engagement of pawl 73 with the rack operates to rotate the drum a space laterally, to both induce entrance of further semi-formed collars into the drum grooves from the funnel hopper 63 above and also move another vertical chute toward the discharge port 65. From the sprocket wheel 41 on the reverse of wheel disk 40 a drive chain ascends diagonally to the driving sprocket 75 of a sprocket wheel 76 that is pivoted at the top of main standard 2, adjacent the funnel hopper edge. This wheel 76 on its main sprocket carries a conveyor chain of linked segments 77 that passes down the inner side of main standard 2 and around a suitable sprocket wheel 78 that is pivoted on said standard 2 adjacent its base, thence ascending along the rear face of the standard through a lower hopper 79-preferably usable for feeding open collars in bulk because more accessible, that is mounted on the standard 2 rear face and designed to feed its contents against the ascending conveyor chain 77, the linked segments of which are designed to engage semi-formed collars in desired position and lift them to the upper funnel feed hopper 63, discharging them into same as the chain links invert in going over the sprocket wheel 75 adjacent the edge of said funnel hopper.

The operation of this my complete decapper-receiving, final-forming and applying machine which incorporates my mechanism for this purpose claimed herein as most desirable is effected as follows: First it is assumed that the machine is set up beside a chain conveyor for bottles and its connection therewith established by adjustment of brackets 6 and 21 to engage the said conveyor and suit the height of the bottles used, the latter adjustment providing that the steadying cone on bracket 21 will have enough rise and fall to enter and lift clear of the bottle mouths. Vertical adjustment of the brackets 6 and 21 is, of course, effected through their slidable mounting on and in the lesser standard 3 and the collar 18 and use of set screws 9 and 20. Then, preferably, the lower hopper is filled with the partly arcuated, open collar,

gency, normally functioning as a feeding reservoir of the open-formed collars passing to feed channels. The ascending conveyor chain 7? then passing upward on the inner wall of lower hopper 79 engages a succession of the open collars in its linked segments and carries them up to the top of main standard 2, where the conveyor chain inverts its linked segments as it passes over the sprocket wheel 75 at the edge of upper hopper 63 and thus dumps the carried blanks into said hopper, one after the other, in best position to facilitate their descent down the funnel-like wall of said upper hopper to the shaft 62 in same and the top of feed drum 61. There it either immediately enters one of the vertical grooves or slideways of the drum, as 64, or awaits proper entrance thereto alone or as one of an accumulation of blanks thereat, through the rise and rotative fall of said feed drum in the funnel shaft by operation of the mechanism below same: the agitator bar 59; driving bar 55; disk wheel 40; pawl 73; and rack collar 69. The open collar decapper, as 80, having entered and descended to the bottom of one of said slide grooves, as 64, awaits rotation of that groove to the discharge port 65, where it slides down a discharging slideway 81, dives headfirst into an opposed opening or trip hole 82 in the frame of bracket 32 at that point which is suitably smaller than the blank body, so that the body Weight causes the blank to swing around, pivoted on the trip hole edge, and drop downward through the opening 58 above the stop ledge 57, to come to rest on said ledge in front of arbor 53 in proper position for shaping die action. The shaping die 45 then advances against the decapper blank (open-formed collar) by operation of drive bar 55 and its eccentric pivoting on wheel 40, and pushes the blank against arbor 53, which stops the central die member 47 and causes wings 48 and 49 of the die to converge under the advancing pressure of the die body 50 on them through the spring plate 51, as the die body slides along the shank of the retarded center member 47, which abuts the blank and arbor, and the wings 48 and 47 press the blank sides forward and around the shaping arbor. Then in the withdrawal of the shaping from the arbor the central member 47 of the die is static and the wings 48 and 49 have no rear pressure upon them other than that exerted by the weak plate springs 51A and are diverged largely by the wedging effect of the arbor curvature upon their outer ends, thus pulling the fully formed blank (now a fully arcuated collar and laterally resilient) off the arbor by engagement of the wing recesses with the ears 83 now extending laterally from the collar. This engagement of the wings of the shaping die with the ears of the fully arcuated collar pulls the collar back fiom the arbor to a point where the wings release it above the exit well 33, by central die member 47 butting at rear end against a stud 47A while the shaping die body recedes farther, thus extending the wings. Then the fully arcuated decapping collar, embracive of the slide post 31 in said exit well 33, slides down to come to rest upon the top of the applying plunger 24and drop ofi same as it recedes or lands immediately in front of said plunger if it is already receded enough. The next forward movement of the applying plunger 24 then pushes the fully arcuated collar decapper onto the head and neck finish of the bottle that is travelling on chain conveyor 7, which has at that moment reached the peak of its interception on said conveyor by the arms of star wheel 9 and the dip of steadying cone 29 into its mouth, and is backed by the end arm 8 of bracket 6. The bottle, with collar decapper duly applied to it, then continues on its way to filling and capping operations-and the action is repeated.

I claim:

In a mechanism for bending decappers to conform to the shape of a particular bottle neck so as to adhere thereto and extend around the same over an arc of more than 180 degrees, the decapper being preformed with a length corresponding to the length of the above mentioned are and being provided with ears near its opposite ends, a die mechanism and an arbor having a shape corresponding to shape of the bottle neck, but of less diameter, disposed to receive a decapper therebetween, said die mechanism comprising a reciprocably mounted body member, a slidable center member mounted in said body member, means for reciprocating said body member, wings carried by said slidable center member, said wings being arranged for engagement with a decapper, means for moving said wings to an open position as the body member is moved away from said arbor, means to cause convergence of said wings when a decapper carried thereby is forced against the arbor during the forward movement of the body member, the arrangement of mechanism being such that said center member and wings thereon engage and carry a decapper against the arbor, bend the decapper about the arbor, then remove the decapper from the arbor through the interengagement of the ears of the decapper with the recesses in the wings, and finally releases the decapper near the rearward limit of the movement of body member.

2. In a mechanism for bending decappers to conform to the shape of a particular bottle neck so as to adhere thereto and to extend around the same over an arc of more than degrees, the decapper being preformed with a length corresponding to the length of the above mentioned are and being formed with projecting ears near its opposite ends, a reciprocably mounted die mechanism and an arbor having a shape corresponding to the shape of the bottle neck, but of less diameter, disposed to receive a decapper therebetween, means for reciprocating said die mechanism, and a fixed part located in the path of movement of said die mechanism, said die mechanism comprising a body member connected to said reciprocating means, a center member slidably mounted in the body member, wings hinged on said center member and having recesses to receive the ears of the decappers, said wings also having arms which are received in said body member and disposed to engage with inwardly projecting means on the body membeer to cause opening of the wings when the center member is moved forwardly with respect to the body memher, said fixed part being arranged to engage with said center member in its travel away from said arbor and produce divergence of said wings, and spring-pressed means in the body member engaging the arms on said wings and yieldly acting to hold the wings in open position, said spring pressed means also acting in conjunction with said arms to move the wings toward a closed position when the center member is moved rearwardly in the body member by engagement of said center member with the work and arbor, the arrangement of mechanism being such that the center member and the wings engage and carry a decapper against the arbor, bend the decapper about the arbor as result of the center member being moved rearwardly in the body member, then remove the decapper from the arbor through the interengagement of the ears of decapper with the recesses in the wings, and finally releases the decapper due to center member being forced forwardly in the body member by abutting said fixed part while the body member continues to move away from the arbor, thus fully diverging the wings.
