' Patented sept. 2, 1919.

Application filed April 29, 1916. Serial No. 94,497.

To all 'whom t may concern:

4Be it -known that I, ERNEST D. ANDERSON, a citizen of the United States, and resident of Long Beach, in the county of Nassau and iState of New York, have invented certain new and useful Improvements in Can Forming and Heading Machines, of which the following is a specification. I

An object of my invention is to provide a machine for automatically forming can bodies, applying heads upon such can bodies, and for seaming said heads upon the endsof the bodies in a continuous or successive manner.

Another object of my invention is to provide -pneumatically controlled means for seaming heads or closures on can bodies, a further object being to cause such means to rotate around the can body and the head applied thereto, for seaming the head and body together, in a continuous manner.

A further object of my invention is to provide means for automatically beading the end portions of the bodies opposite the head applied thereon, and 4delivering the headed and beaded bodies from the machine.

Other objects of my invention, as well as novel details of improvement and combinations of parts, will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanying drawings forming part hereof, wherein,

Similar numerals and letters of reference indicate corresponding parts in the several views.

In the accompanying drawings the numeral 1 indicates a suitable frame adapted to support mechanism hereinafter explained. In the example illustrated, the frame 1 is equipped with a rotative device which I term, generally, a turret indicated at A, and with a substantially similar turret B, said turrets being suitably spaced apart. The turret A is provided with receivers for can bodies, that are adapted to successively receive can bodies from a can-body forming machine, or from any other desired source of supply, and while retaining thev bodies thereon to present the bodies in different positions for different operations, such as for straightening the bodies, applying heads thereto, seaming the heads on the bodies, and delivering the headed bodies from said receivers. Where the can bodies are to be beaded adjacent to their ends opposite the heads, the turret B is utilized, and as illustrated, is provided with means for taking the headed can-bodies from turret A and presenting them to devices for performing certain operations thereon, such as for forming the beads adjacent to the open ends of the can bodies, pressing the longitudinal seams of the bodies at the beads, and discharging the headed and beaded bodies.

Referring now more particularly to the turret A, and the devices coperative therewith for applying and seaming heads on the can bodies, it will be understood that the turret comprises various coperative parts which may be described as follows: A vertically disposed shaft 2 is suitably journaled in bearings in the bed plate of frame 1, and said shaft is shown provided with a bushing or the like 3, shown resting upon frame 1 and secured thereto (Figs. 6 and 20) upon whiclrbushing rests a turret plate 4 centrally disposed upon said shaft and suitably secured thereto, as by a key. Turret plate 4 is provided with a suitable number of radially disposed grooves or channels 5 (Figs. 20 and 21), in whiclrslides 6 are disposed so as to slide radially. The slides 6 are provided with receivers 7 for can-bodies b, which receiversare shown provided with longitudinal grooves at 8 to receive the can-body seams. and at 9 the receivers are provided with can-body retainers, adapted to enter the bodies to retain them on the receivers 7 (Fig. 3). The retainers 9 are 'shown loosely mounted on the receivers 7 and held in place by pins 10 entering slots 11 in said receivers, springs 12 between receivers 7 and retainers 9 serving normally to press the latter outwardly. The outer ends of the receivers 7 and of the retainers 9 are shown beveled or tapered for ready entrance into can bodies. The receivers 7 have abutments or stops at 13 against which the ends of the can bodies must abut for centering the bodies on the receivers and resisting end thrust of the bodies. While the receivers may be formed directly on the ends of the slides 6, said receivers are preferably made separate therefrom to fit u on projections 6n at the outer ends of the s ides, clamping means, such as screws 14, (Figs. 2, 3) serving to securely hold the receivers 7 on the slides. The outer ends of the receivers 7 are shown provided with recesses 15. A plate 16 secured upon plate 4, retains the slides 6 properly in the grooves or channels 5, (Fig. 20). Plate 16 is retained on plate 4 by means of screws. Plates 4 and 16 are comprised in the turret, and the latter is -held on shaft 2 by nut 17 receiving threadsl upon the end of shaft 2 and bearing against an interposed washer or the like 18 (Fig. 20).

The slide-carrying plate 4 is to be rotated step by step, and each time said plate stops a can body may be placed upon one of the receivers 7. I have illustrated means to automatically feed can bodies to the appropriate body-receiver 7 the discharge end of said delivery means being indicated at 19 in Fig. 1. The means illustrated for delivering can-bodies to receivers 7 will be more fully hereinafter described.

Any suitable means may be provided for rotating the slide-carrying plate 4 step by step. For such purpose I have illustrated tempo@ a Geneva movement comprising an escapement Wheel or plate having radial grooves 2l corresponding in position to the slides o, and secured upon shaft 2 (Figs. 6 and 26). An arm 22 having a projection or roller at 23 to enter grooves 21 rotates escapement,

wheelv 20 in an ordinary manner. Arm 22 is secured upon a shaft 24 carried in suitable bearings on frame 1, and shown provided with a bevel gear 25 meshing with a bevel gear 26 on a drive shaft 27 journaled in suitable bearings on frame 1, (Fig. 6). Shaft 26 may be driven in any suitable manner, such as by a sprocket wheel 28 secured thereon, receiving a chain 28a from any suitable source of power, such as from the can-body forming machine as hereinafter explained. Each time wheel 20 is moved a step a-can body receiver 7 will be brought to rest in position to receive a can body from the delivering part 19.

In order to properly seat can bodies on receivers 7, and to straighten the edges of the can bodies with respect to their seams, I preferably cause the can bodies to be brought at their first stopping point opposite an abutment 30 secured on frame 1, and having a suitable surface to receive the outer ends of the can bodies, (Fig. 1). rlhe abutment 30 is preferably provided with a pin or project-ion 31 to enter the recesses 15 of receiver 7 to cause the latter to be properly centered when the receivers with the can bodies are successively pushed toward said abutment (Fig. 1), as will be presently explained. At the next step, each can body is. brou ht to rest in position with respect to means or applying heads a upon the bodies l) (Figs. 1, e1, se and. es). trated of the class having the depressed ortion a adapted to enter the can body at its end,'while the flange a2 of the head projects Voutwardly to be seamed over theed e of the can body (Figs. 31, 34 and 3LP). n the example illustrated a suitable magazine Ifor heads a is illustrated at 32, carried by a standardla on frame 1, adapted .to receive aasuitable'stack ofjheads a (Figs. 1, 6 and 31), fin ers at 33, pivotally supported upon standar 1,, engaging the lowermost head of the stack, springs 34 coperating with said fingers and the magazine serving normally to retain the fingers closed with respect to theheads for supporting the latter. Beneath the magazine 3-2 1 have shown means for' taking ofi' the lowermost head a ofthe stack and presenting it opposite the n can body on the opposing. or adjacent body 'receiver 7, the arrangement shown for such purpose being as follows: A rocking arm 35 is shown carried by a shaft 36' journaled in bearings upon standard' 1a (Figs. 31 and 33), and said arm 35 is shown provided with' a hollow or recessedfportion which recelves s a polygonal block 37 through which a shaft The heads a are illus- Ito receive a can bo 36 asses. A spring 38 interposed between sai block and the outer end of arm 35 normally tends t0 move said arm toward the left in Fig. 31. At the outer end of said arm is pivotally supported a head 39 recessed at its Aouter end and adapted to enter the recess of the can heads a. Head 39 is shown pivotally supported upon a shaft or pin 40 carried by arm 35, a spring 41, interposed between arm 35 and head 39, normally tending to push said head forwardly-v to a tilted p0- sition to resiliently engage can heads, 'and enter them angularly. A tube d leads from a source of air suction or exhaust to a port 39a in head 39. On opposite sides of arm 35 are arms 42 secured upon shaft 36 and having suitably curved cam-like forward edges 42a adapted to coact with shaft 40, or with rollers 43 thereon (Fig. 33), to cause required movements of arm 35 and head 39. Shaft 36 is to be rocked at a suitable time, for which purpose l have shown said shaft provided with a toothed segment 44 in mesh with a rack 45, suitably guided upon standard l and pivotally connected by a link 46 with va rock arm 47, pivotally supported by frame 1 and connected by a link 48 with a crank 49 carried by shaft 27 (Fig. 6). When arm 35 is in the position for application of a head a to a`can body said arm will bear against a stop 50 on standard 1a, as in full lines `in Fig. 31, and when said arm is vbrought to the can-head receiving position of arms 42 causing arm 35 to be carried with arms 42, and when arm 35 rests against stop 51 head 39 will be in proper position beneath the can bodies. A further movement of arms 42 to the left in Fig. 31 will cause arm 35 to be pushed upwardly to bring its head 39 in engagement with the lowermost can head a; in the stack, by reason of the cam surface 42a in coaction with shaft 40,'and thereupon suction through tube a? Will be caused by any suitable means to pneumatically retaln such can head on head or plate 39. rllhe racks w1ll then so operate that arms 42 will return to the right in Fig. 31,I and spring 38 wlll cause arm 35 to descend and carry withl 1t said lowermost head a, dragging it from be tween the spring acting ngers 33, whlch ywill thereupon snap under the lowermost head aof the stack to retain the stack in the magazine, While permitting the can-head upon plate 39 to move away wlth arm 35. Said arm with arms 42 will continue to move to the right in Fig. v31 until arm 35 rests against stop 50, Ibringing head a in position/v y When the parts are in such position (Fig. 31) the now opposing can receiver 7 will be moved with can body toward the head a that is upon head 39,' and when said head has been entered in the can body, (substantially as shown in Fig. 34), and retained by friction, suction through tube d will be cut off, and the can body with the head applied w1ll be withdrawn, the movement of the can body toward and from head 39 being effected as presently described. The foregoing operations occur with each head to be applied upon a can body in succession.

After a head is applied upon a can bod the turret A will rotate to carry the headed can to the position to have the flange :z2

' seamed on the body. In the example illus- `tra-ted in the accompanying drawings, thel arrangement is such that the turret will make two stops from the position where the head is inserted in the can body to the position where the flange a2 is seamed on the can body, as illustrated in Fig. 1. The devices for seaming heads on can bodies are shown in detail in Figs. 15 to 19, and comprise means to bear on and rotate around the flanges' of the heads, and to be pressed thereon under pneumatic pressure in accordance with the shape of the can and its head. A

Spindle is supported on a bracket or the like 56 secured on frame 1, and is providedF with a suitable chuck 57, substantially conforming to the shape of the can head a and adapted to enter the recess thereof. The chuck 57 is preferably detachably connected with spindle 55, as by means of a screw 58 (Fig. 19).l At 59 are rollers suitably spaced apart around the chuck 57 and pivotally supported upon arms 60 to move relatively toward and from chuck 57. The arms 60are pivotally supported at 60a' upon a rotative head 61, that 1s mounted to rotate upon spindle 55, and which may be driven by a belt from `a suitable source of power, or in any other suitable manner. The arms 60 and thereby the rollers 59 are maintained, during operation, pressed toward the can heads presented thereto upon the corresponding receiver 7, and for such purpose I have shown head 61 provided with cylinders 62 in which are located pistons 63 operatively connected with the corresponding arms 60. For such purpose I have shown arms 60 provided with projections 60b receiving pins 64 carried bythe respective pistons 63. The arms 60 also carry suitable rollers 65- adapted to bear upon a master form 66, that is slidable upon spindle 55, and around which master form the rollers 65 roll when head 61 rotates. Means are provided to supply fluid pressure n in thecylinders during the operation of the seaming on the can heads to cause the rollers 59 to press on the flanges of the can heads.

I have shown the head 61provided with an annular channel 67 communicating with the packing held in place by screws 71. The v packing may be retained in place by a suitable nut or gland 71a (Fig. 15). The channel 67 may be provided lbetween the periphery of head 61 through which the cylinders open, and a shell or ring 67 surrounding and fitting tightly thereon, and held in place by a nut or ring 67b on head 61, (Figs. 15 and 16). By removing shell or rin 67 access may be had to the cylinders an pistons. The chamber 69 may be supplied with compressed air through a channel 72 in spindle 55, the inner end or port 73 of said channel communicating with chamber 69, while the outer end of the channel is connected by tubing 74 with a source of compressed air supply. The passage 75 in spindle 55 may supply lubricating oil to the bearing of rotative member 61, as through a tube 76 from a suitable source of supply. The master form 66 is preferably shaped substantially to conform to the sha e of the can body and its head, the shape illustrated in the accompanying drawings being substantially oval. By means of rods 77 slidable in bores in spindle 55, and suitably connected with master form 66, said master form may be slid back and forth along spindle 55 by any suitable means, suitaby tuned to permit rollers 55 to gradually approach the can head as the flange lthereof is reduced in diameter by the pressure of said rollers thereon. I have illustrated means in Fig. 1 for causing such movement of master 65 as will be presently described. (The arrangement is such that whena can Ibody with its head applied (Fig. 34) is presented to the chuck 57 1t is pushed thereon a suitable distance, while the master 66 is substantially in the position shown in Fig. 15, holding rollers 59 retracted. As the head 61 with the pistons and rollers continually rotate, the master 66 will be gradually pulled outwardly from under the rollers 65, therebypermitting the air pressure against the pistons to force the rollers 59 against the flange of the can body for rolling the same down for seaming the flange, the continued outward movement of master 66 permitting the rollers 59 to act wn the flange a2 to the desired extent.

c. For this purpose all of the cylinders 62 communicate with the single channel 67, whereby the pressure in the cylinders will be equalized, while the pistons are caused to reciprocate by contact with the oval or other shaped flange of the can head during rotation of member 61. Suitable means, such as an automatically operating valve, may be provided for causing pressure in channel 67 to be started just before the master form 66 is pulled to the right in Fig. 15, and to be relieved just before master form 66 is pushed to the left in Fig. 15, to then relieve thc pressure of rollers 65 on said master, so that when the master form is pushed to the left to cause withdrawal of rollers 59 to the opened or spread position, the work of pushing the pistons outwardly against air pressure will be reduced. The desired pressure may be admitted to channel 67 just after a can body with its head a applied is presented between rollers 59, and such pressure may be continued until said rollers have acted sufficiently or as desired upon the flange of said head. lin Fig. 1 the tube 74, which may communicate with the corresponding channel 72 of both rotary v seaming heads, connects with a suitable airf controlling valve 78 receiving compressed air through pipe 79 from a suitable source.

` A cam 80 (Figsfl and 6) on shaft 27 may operate an arm 81 for controlling valve 78 at the required time to admit air preure to and relieve it from channels 67. Valve 78 may have a vent to relieve the pressure in channels 67. Valve 78 may be any wellrnown quick-acting valve such as ordinarily used for. air or steam.

While `the desired action of rollers 59 upon a can-head flange may be utilized with a single rotary head 61 for seaming, it is preferable, in solne instances, toutilize two 'of such sets of devices, as illustrated in Fig.

1, the Iirst set (at the left in Fig. 1) for partially turning or seaming the flange and the second set for completing such seaming. The two rotary heads may be substantially the same as described with respect/to Figs. 15 to 19a, but will be so set with relation to each other and to turret A that the rotary head 61 Vatthe right in Fig. 1, will` be in position to receive a partially seamed can body and head on the next step of turret A after a body having a partially seamed head has been withdrawn from the left hand rotary head 61 in said li re. When the partially seamed flange o the can bod has been presented in right hand 'rotary ead 61, the pressure will be admitted in its channel 67 for causing its plstons and rollers 59 to act with'the required pressure for finally seaming Athe flange a2, the corresponding master 66 being operated in a manner before described. The masters 66 may be automatically actuated, and said masters of both rotary heads may be operated together by the following means: Rods 77 of the left hand head 61 are secured to a block 82 (Fig. 1) that is connected with a bell-crank lever 83 pivoted upon bracket 56 ;y a rod 84 pivotally connects lever 83 with a corresponding bell .crank lever 85, pivotally supported upon bracket 56 with respect to the right hand rotary head 61, arm 86 connected with lever 85 being is connecte to the rods 77 of the right hand Vhead 61. A rod 88 is pivotally connected at one end with lever 85 and at the other' end said rod is provided with a guide yoke 88EL having a pin 89 coacting secured upon shaft 24a journaled in bearings in frame 1 (Figs. 1 and 6). As cam 90 is rotated, the rods 77 of the respective rotary heads 61 will be reciprocated at the "proper time for movin the respective mas` ter forms 66 back an forth with respect to the corresponding rollers 65 of the respective pistons. After the seaming has been finished upon the can head, by the devices of the right liand rotary head 61 (Fig. 1), the can body is withdrawn from said head and at the next step of turret A said can body is brought to a position indicated at :a in Fig. 1, ready to be discharged or removed from the corresponding receiver7.

While any suitable means may be provided for rotating turret Astep by step, and for causing the can body receivers 7 to be projected outwardly and drawn in with can bodies thereon, I have illustrated means for such purpose as follows: Since turret A is illustrated as provided with eight can body receivers 7, the plate 4 is shown provided with eight grooves or recesses 5 receiving the corresponding slides 6 (Fig. 21) and the Geneva wheel 2O is shown provided with eight correspondingly disposed grooves 21 (Fig. 26), whereby the turret A will be given eight steps for each complete rotation thereof. Since, in the example illustrated, there are six points at which operations occur with respect to a can body, such as the application of a body to a receiver 7, the straightenin of the seam .of the canV body, at 30, the application of the head to the can body adjacent to the magazine 32, the seaming of the flange of the can body head a-t the two rotary heads 61, and the delivery point for the headed can bodies at the point m, I provide means to cause the receivers 7 to be moved outwardly and 1n- Wardly for each of'such six polnts, the other connected with a block 87 that with a cam two 4points at which the lreceivers 7 are brought 'by the rotation of Geneva wheel 20 not requiring relative movement of the reh points I provide devices as followsz'Beneath plate 4 and concentric with rotatively guided shaft 2 is a plate 92 (Figs: 6, 20, 22 and 23). Plate 92 is shown provided with six appropriately located radially disposedl slots or grooves 92", shown opening through the periphery of sald plate, adapted to slidably receive blocks 93. Said blocks are shown rovided with lianges 93", on opposite si es, bearing against lthe bottom of plate 92, which blocks s'lidably rest upon a cam plate 94 that is rotatively supported beneath plate 92 and guided around shaft 2, (Figs. 6, 20, 22, and 23). Plate 92 is shown provided with an annular groove or raceway 92" (Fig. 22) which communicates w1th the slotsy or grooves 92". The lblocks 93 are provided with transverse grooves 93", which open through the sides of said blocks, which grooves 93" are adapted to coincide with the annular groove or raceway 92" of plate 92,

vin certain positions of blocks 93 (Fig. 22).

Heads 95 are adapted to slide in groove 92", being shown provided with curved surfaces for such purpose (Figs. 22 and 25), which heads are adapted to enter the grooves 93" of blocks 93 to Ibe moved therewith radially respecting plates 92 and 94 (Figs. 20, 22, 23, 24). Heads 95 receive pins 96, shown adapted to t in openings 95 of said heads, and also fitted in openings in slides 6, said pins being adapted to slide in radially disposed slots 4" in plate 4 (Figs. 20, 21 and 23). Since, in the example illustrated, there are eight slides 6, there will be a corresponding pin 96 and head 95 for each slide 6, and since there are six points at which operations occur with respect to the can bodies of turret A, 'the six grooves 92" and six blocks 93 in such grooves will suffice, although all of the eight heads 95 may operate in succession in the grooves of corresponding blocks 93. When a head 95 is in the groove of a block 93, the latter is tobe moved radially,`

and a corresponding slide 6 with its can body receiver 7 will be correspondingly moved because of the interposed pin 96. Any suitable means may be provided for reciprocating blocks 93 in grooves 92"l of plate 92 atthe proper times. For such purpose I have shown plate 94 provided with cam grooves 94a positioned with respect to grooves or slots 92 of plate 92 and adapted to receive pins 97 that project from blocks 93 (Figs. 22 and 23). By preference, rollers 98 are carried by pins 97 for engagement with the cam grooves 94a. Pins 97 may be retained in position by nuts 99 seated in recesses 93c in blocks 93, (Figs. 20 and 24).

The` arrangement described is such that when c'am plate 94 is rocked or oscillated, its grooves 94", by coactiomwith pins 97, will cause blocks 93 to be reciprocated. When plate 4 is brought to rest a head 95, corresponding to a slide 6, is presented in the groove 93" of one of the blocks 93, and then cam plate 94 is given a to and fro movement, whereupon its cam Grooves 94a cause blocks 93 to move outwardly and then inwardly, carrying slides 6 and. receivers 7 therewith, terminating the stroke with heads 95 in register with groove 92" of plate 92. On the next step of plate 4 the heads 95 pass through groove 92" until certain of said heads rest in the grooves 93" of the next adjacent blocks 93, whereupon cam plate 94 is again moved to and fro to cause certain slides 6 to be again moved outwardly and inwardly, and so on each step of plate 4 where slides 6 are to be given a to and fro movement. The foregoing pertains to six of the slides 6, whereas the heads 95 of two other slides, not then to be reciprocated, as with respect to the points y and y2 (Fig. 1), will be 1n the appropriate parts of groove 92" of plate 92, and so on. The means I have shown for oscillating plate 94 are as follows: At 100 is a cam secured upon shaft 24 above frame 1, (Figs. 6, 27 and 35), and adapted to coact with a pin or roller 101 carried by a rod or link 102, shown having a forked end 102a guided by shaft 24, the opposite end of said rod or link being pivotally connected With plate 94, as by pin 103, which is shown adjustable in a slot 104 in plate 94 (Fig. 27). When heads 95 havefbeen presented in grooves 93" of blocks 93, and plate 4 has come to rest, cam 100 will, through link or rod 102, cause plate 94 to be rocked or reciprocated to and fro one stroke each way, whereby the cam slots 94a will cause blocks 93 and slides 6 to be moved in and out, terminating the stroke with heads 95 in register with groove 92" of plate 92.

If no further operations are desired to be performed upon the can bodies while they are carried by turret A, after the bodies have been headed and seamed, the can bodies may be removed. In the example illustrated in the accompanying drawings I have provided means for removing the headed can bodies from turret A and supporting them upon a second or companion turret B that is spaced a suitable distance from turret A upon frame 1. Turret B may be made substantially in the same manner as turret A and provided with a corresponding number of can body gripping or receiving devices indicated generally at 7, which may be removably attached upon the ends 6" of slides 6, as by clamping screws 14a in manner similar to that described with respect to slides 6. Turret B may have plates 4 and 16 receiving slides corresponding to slides 6 of turret A, together with' the plates 92 and 94 and interposed blocks 93 and pins connecting saidA parts, in manner described with respect to turret A, for causing the gripping or receiving devices 7a to be projected and retracted as turret B rotates step by step. A Geneva movement, having a camwheel 20 provided with slots 21L and an arm 22 having a pin or roller to coact with said slots and carried by a shaft 24 supported by frame 1 may be operated in timed relation to turret A throu h gearing 25, 26 andV shaft 27 for causing step by step rotation of turret B simultaneously and coincidently with respect to turret A, (Fig. 6). lin the example illustrated the can bodies having the heads seamed thereon, as hereinbefore described, are brought to rest successively upon a receiver 7 of turret A, opposing a gripping or receiving device at 7a of turret B, and at suitably spaced distances around turret B means are provided for beading the can bodies adjacent to.

their ends at b2 (Fig. 14) opposite their heads, at the position shown ai; z Fig. 1, and for bumping or pressing the seams at the beads b2, as at the point e2 (Fig. 1), and for delivering the can bodies from turret B as at the point e (Fig. 1). Since, as illustrated, there are but four points of operation with regard to the can bodies respecting .turret B, it will only be necessary to cause the gripping or receiving devices 7L to be projected and retracted at each of such four points. Hence, as shown in Fig. 28, plate 92 is provided with four radial grooves 92f (correspondin to the grooves 92a, Fig. V22), and plate 94 as four corresponding cam slots 94t (corresponding to the cam slots 94 of plate 94 Fig. 22). Flate 4 carrying the slides 6 that support the grippers or re ceivers 7, will be provided with eight slots and slides in the manner illustrated and described with respect to Figs. 20 `and, 21, and the pins 97a from blocks 93 will work in the cam slots 94t similar to the corresponding parts described with respect to turret A. The blocks 93 have transverse grooves93 adapted to receive blocks 95 receiving pins 96 (Figs. 28, 29, 30) from the corresponding slides 6, (in manner de scribed with respect to similar parts in` Figs. 20 and 21). Plate 92 has the annular groove 92g communicating with the slots or grooves 92f for the passage of the heads 95, (in manner similar to that before described regarding turret A). Turret B is mounted upon'a shaft 2 connected with Geneva wheel 20a in manner similar to the connection of shaft 2 with Geneva wheel 20 of turret A. Cam plate 94 of turret B is to be rocked to and fro in unison with cam plate 94 of turret A, for which purpose a rod 105 (Figs. 1, 6, 22 and 28) is pivotally connected to plate 94 at 106 and with\plate 94 at 107,

lbody from receiver 7.

and `by, means of suitable pin and slot connection between said rodl and said plates adjustment may be made for accurate movement of one plate by another. Such lpin and .slot connection may be similar to that shown in Fig. 27a. By the means described the single cam 100 may be utilized for oscillating plates 94 and 94e in unison and to the same extent to assure that the respective slides 6 and their opposing receivers 7 and 7a (Fig. 1) will all work together in proper timed relation.

The receivers 7a of turret B are provided' with means for gripping the headed ends 0f the can bodies and removing said bodies from the receivers 7 of turret A and retaining said bodies for operations thereon and discharge thereof from receivers 7. As shown in Figs. 1, 4 and 5 the receivers 7a are provided with gripping fingers 108 pivotally carried by shafts at 109 on opposite sides of the receiver adapted to grip the headed end of cans b therebetween. Springs 110 connect arms 111 respectively secured to shafts 109 for normally drawing the fingers 108 toward the can body. One of the shafts 109 of each receiver 7a is provided with an arm 112 for causing discharge of the can bodies as hereinafter explained. The shafts 109 are connected by projections 113 with a plunger 114 slidable in a bore in the corresponding receiver 7, and normally held retracted in line with the head of a can body when the latter is held between the ngers 108. When arm 112 has operated fingers 108 to release a can body the plunger 114 will be pushed forwardly to vdischarge a When a headed can body is brought to rest on a retracted receiver 7 at the point :c (Fig. 1) a receiver 7EL will be retracted opposite said can body. When the plates 94 and 94 are next rocked to cause the corresponding slides 6, 6, to move outwardly, the receiver 7 carrying the can body and the receiver 7a opposed thereto move toward each other, andthe corresponding fingers 108 snap over the headed end of such can body and then when plates 94 and 94e are again rocked reversely said receivers 7 and 7a are moved apart and the can body, `then held by fingers 108, is withdrawn from receiver 7 and retained upon receiver 7. On the next rotary step of turret B in the direction of the arrow there0n.`(Fig. 1) said receiver is not projected outwardly, but on the next step of turret B, said receiver, with the can body thereon, is projected outwardly by the appropriate cam slot 94E to locate the open end of the can body in position to be beaded adjacent to said end, at the position e (Fig. 1). Devices for beading can bodies are shown in Figs. 1, 6, 7, 12, 13, and` 14. At 115 is a head supported by a bracket 116. carried by frame 1, in position opposite a can body whenbrought to rest by turret B.
