Application tiled August 2. 1902. Serial No. 118,097. (No model.)-

To a/ZZ whom, it may concern.:

Be it known that we, CHARLES STECHER, of Point Edward, Province of Ontario, and Dominion of Canada, and PETER FULFORD,` of Port Huron, in the county of St. Clair and State of Michigan, have invented certain new andv useful Improvements in Machines for C onnecting'Can-Heads with the Bodies Thereof and we do hereby declare that the following is a full, clear, and exact description thereof, reference beinghad to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvementsin machines for making sheetmetalcans, and

refers more specifically to machines 'adapted to place can-heads upon the bodies thereof and to `crimp the flanges of the-heads upon.`

said bodies, the operation' being a combination of what is known as a headingland' over, the mechanism may also be employed for crimping` cans the heads of which have already been placed upon the bodies.

So far as certain of the features of our invention are concerned the machine may embrace but a single heading and crimping mechanism. Y

The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a side elevation of a machine embodying the improvements constituting our invention. Fig. 2 is a top plan view thereof with the feeding-chute removed and other parts broken away. Fig. 3 is a vertical section taken on line 3 3 of Fig. 1.

Fig. 21 is a section taken on line 21 21 of Fig. 17.v Fig. 22 is a detail of the finger-actuating plungers and cross-bar or yoke, showing the latter in section.

A machine embodying our invention embraces generally two sets vof mechanisms for connecting can-heads with the bodies thereof, (whichmechanisms may be combined heading and crimping mechanisms or individual heading or crimping mech anisms,) a carriage reciprocating between rsaid mechanisms and provided with means for carrying the'can heads and bodies set by set and deliveringy them to said mechanisms, and a deliverychute located between said mechanisms and over the carriage and adapted for delivering Fig. 13

the can heads and bodies set by set to said' A carriage as the carriage reciprocates beneath the same. The double or heading and crimping form of the mechanisms is herein shown. The parts are so arranged that when the carriage is at one limit of its movement it is in position to deliver a set ofY can members to one of the heading and crimping mechanisms,

rco

and the other end of the head is in position to receive a set of can members from the feed-chute. After one set of can members has been delivered by one end of the carriage to one of the heading and crimping mechanisms the carriage is shifted to the other heading and crimping mechanism to deliver to said mechanism the set of can members which has just been received by said carriage from the chute, while the end of the carriage from which the set has just been released is moved into position to receive another set from the chute. In the continuous operation of the machine the carriage reciprocates backwardly and forwardly beneath the chute and between two combined heading and crimping mechanisms and acts to alternately deliver sets of can heads and bodies thereto, whereby the capacity of the machine is greatly increased as compared to a machine having but a single heading and crimping mechanism.

Referring now to the details of construction of the machine herein illustrated as one example or embodiment of our invention, said construction is made as follows:

A designates a horizontal frame-plate which is rectangular and is supportedon standards A' A', located one at each corner thereof. i B B designate in a general way, as shown in Fig. 2, combined heading and crimping mechanisms located one at each side of the frameplate and near the longitudinal center thereof and constructed to simultaneously force both candieads upon the body thereof and to crimp the ilanges of said heads upon' the body. l

C designates a horizontally-movable carriage which reciprocates between the heading and crimping mechanisms and moves in transverse guides or ways a in the frameplate, as shown in Fig. 3. Attached to or formed on said carriage is a head, designated as a whole by D and which is constructed to receive the can heads and bodies from a chute E, located over the path of the carriage, said chute being located centrally between the heading and crimping mechanisms. The chute preferably consists of a lower vertical part and an upper oblique part, which latter is made of a length to extend away from or clear the frame-plate, whereby c in heads and bodies may be easily fed to the chute.

The construction of the chute is more clearly shown in Figs. ll to 14E, inclusive. Said chute is provided with a central runway for the can-bodies and is made of a crosssection to correspond with the shape of the can-bodies. The chute consists at its lower end of side members e e and edge members e e', suitably secured together by angle-bars, as shown in Figs. l2 and 14, and forming the central runway for the can-bodies. At the sides of the chute are formed narrow runways for the can-heads,said runways being formed between the side walls e of the chute and other walls e2. The edge walls e' e' extend continuously along the chute from end to end and constitute the upper and lower walls of the oblique horizontal part of the chute. The sides walls e are, however, replaced from points below the bend of the chute to the outer end thereof by narrow strips e3, which extend only a slight distance inside the edge walls, and the plates e are replaced by centrallylocated strips or bars c4, which are held in place by means of cross-bars e, as most clearly shown in Figs. 3 and ll. The lower ends of the side walls e and the plates c2 extend below the edge walls e for a purpose to be hereinafter explained.

The carriage C is operated to carry the head D from one end of its travel to the other through the medium of the following mechanism: C', Figs. 1, 3, and 4, designatesa carriage-actuating lever, which is connected at its upper end by a link C2 with a' lug c, extending downwardly from the carriage through a slot in the frame-plate- Said carriage-actuatin g lever C is pivoted at its lower end upon a horizontal shaft a, which is mounted in the lower ends of vertical hangers d2, depending from the frame-plate of the machine, as most clearly shown in Fig. l. Said carriage actuating lever is provided with a hub c', having a rigid laterally-extending arm Connected with said arm c2 is avertical cam-yoke C3, which is provided with a cam-lug c, adapted to engage a cam-groove cL in a rotative cam-wheel C4, which latter is affixed to a longitudinal rotative shaft (15. Said shaft C5 has bearing in hangers a2, depending from the frame-plate of the machine. Said shaft also extends through the hangers a2, which aiford lateral support of the shaft. Said cam-yoke is pivoted at its lower end to a block c5, which has sliding engagement with a groove in the arm c2 of the carriageactuating lever, and said block is ad j ustably iixed with respect to said arm by means of an adjusting-screw c, as shown in Fig. 3. In this manner the throw of the carriage-actuating arm may be increased or decreased, as desired, and therethrough the travel of the carriage regulated. The cam C4 is driven by a pinion F, mounted on a rotary drivingshaft FQ which latter extends to one end of the machine and is provided with a belt-pula ley F2, through the medium of which power is imparted to rotate the same, as shown in Figs. 2 and 3.

The carriage engages at the limits of its movements stops a4, Fig. 3, consisting of bolts which have screwthreaded engagement with up\\'ardlyexte1iding lugs on the frameplate. Said stops act to regulate the travel of the carriage with respect to the centers of the head ing and crimping mechanisms. The screw-threaded connection of the stop-bolts with respect to the frame-plate permits accurate adjustment of the parts.

The carriage-actuating lever C has yielding connection with the link C2, by which it is connected with the carriage, thereby permitting the carriage to be brought to a positive lstop at 'each limit of its movement in proper positions with respect to the heading and crimping mechanisms and at' the same time permits a slight overthrow of the carriage-actuating lever due to wear of the parts or improper adjustment thereof. As herein shown, said lever extendsupwardly into an opening in the bottom of the link and is provided with a cross-pin c7, which engages longitudinal slots o8 on the sides of the link. interposed between said lever and the ends of the slots are spiral springs e9 e9, which act to hold the lever midway between the ends of vthe slots, but permit the lever to yield when the carriage strikes either of its limiting'stops or abutments.

The feed-head D of the carriage is shown as made integral with the carriage, though it may be made a separate part andl attached thereto. The said feed-head, however, in the construction illustrated moves positivelywith the carriage from side to side of the machine and directly engages the sets of cam members to carry the same from the chute to the heading and crimping mechanisms.

The design of the head is shown in Figs. 2, (i, 17, 18, 19, and 20, and consists 'of a vertical web D, which is made integral with the carriage and at the ends of which are formed transversely-arranged concave seats CZ, made of slightlyA less length than that of the can'- bodies to be operated upon, they transverse length of said curved seats vbeing substantially one-half of a circle. Said curved recesses d at the ends of the head pass beneath and are adapted to receive can-bodies from the central runway of the chute. At each side ofthe head is a thin metalfranie D3, consisting p of a horizontal'part cl2, the upper margin 'of which is in the plane of the horizontal top margin of the web D', and curved recessed ends d3, which correspond with and are located at the sides of the curved recessed ends d of the head. Said curved recessed ends ofrthe side plates D3 of the head are adapted to receive the heads of the can and are vtherefore formed on longer radii than the recesses d. Said side plates register with and pass through the lower ends ofthe side runways of the chute for the can-heads, which latter extend. below 'the level of the main runway, as shown in -Fig. 7, so as to receive the can-heads from said runways. Cooperating with said curved recesses or seats CZ of the head are grippingfingers D2, which are made of a width approximately equal to that of said seats d. Said fingers are pivoted on pins CZ', extending through bearings in the web D of said head.

, The length of the curved fingers D2 is substantially one-quarter of the circumference of the can-body, so that when the fingers are swung upwardly against the can-bodies by the means provided therefor, to be hereinafter described, approximately three-'fourths of the can-body is engaged by said head and fingers. Cooperating with the curved recesses Yor seats d3 at each end of the side plates and said ngers the can-heads are' graspedy when said fingers are thrown upwardly. Said fingers D4 are pivoted upon the pins d', one at each side of each iinger'Dz, and are formed on radii corresponding with that of therecesses or seats cl3 and being greater than that of the recesses d, for the reason that the outer diameters of the head-flanges` are obviously somewhat greater than the can-bodies. Y The said ribs Dvof the head'and the upper parts of the curved recesses d thereof are made of such height as to just clear the lower ends of the edge members e of the chute, asclearly shown in Figs. 4 and 7, and the side members DS are arranged in alinement with yand pass through the lower ends of the head-runways, as before stated. With this construction, therefore, when the head is located centrally `beneath the delivery-chute E the can-bodies and can-heads ride on the web Dand the upper parts d2 of the side frames D3, respectively. When the headis moved to one side..

ngers, as Will hereinafter more fully appear.

The downwardly-projecting parts c e2 of the chute, between which are formed the lower ends of the runways for the can-heads, prevent lateral displacement of the can-heads with respect to the body at this time or just after the samehave fallen into the recesses cl3, thereby holding said heads and body in proper position to be, engaged bythe fingersV D2 .D4 when said fingers are thrown upwardly.v

ICO

xc5 I The fingers D4 are made slightly 'wider'than the runways for. the can-heads and are therefore slitted and recessed at their outer ends *for the reception of the lower ends of the Walls e e2 of the runway when the fingers occupy their uppermost positions, as shown in- Fig. 11.

As before stated, the head l) is made of such length with respect to the distance between the chute and the centers of the heading and ycrimping mechanisms that when one end of the head is in position to receive a can from the chute the other end of the head is in position 'to centerthe can members carried thereby with respect to the heading and crimping` mechanism. Means are provided for actu-1 ating said fingers to engage the same with the can members after a set has been receivedthereby from the chute and for also releasing the fingers from another set of can members when the heading mechanism has acted thereon after centering a set with 'respect to the heading mechanism.

The fingers D2 D4 are actuated to throw the same upwardly into gripping relation -with the can members by means of two sets of endwise-movable horizontal plungers G G,which have sliding engagement with bearings el@ of the head, as shown in Figs. 17 and 2l. The innerer adjacent ends of the plungers of each set are seated in recesses in a horizontal crossbar or yoke G2 inside of said bearings cw, and the outer ends thereof extend beyond said bearing and engage lugs di d", respectively, on the fingers D2 D4, below the pivots thereof. The central plunger of each set engages the lug d3 of the associated central or wider finger for the can-body, and the side plungers engage the lugs on the fingers which grip the can-heads. In order to prevent the lingers D4 from buckling the heads and also to afford a yielding grasp of the fingers D1 with the can-heads, such as will permit the same to be forced upon the can-bodies while the headfingers are yet engaged with said can-heads, the ends of the plungers, which actuate the head-fingers, bear against backing-springs g in the cross-bar or yoke G2, as indicated in Fig. 22, The central plungers G are rigidly affixed to said crossbar or yoke.

The two sets of plungers for the two sets of gripping-fingers are located at the same level, the cross-bars or yokes G2 thereof being disposed parallelwith each other, and said plungers are actuated to throw the fingers in their gripping positions by a common actuating device which is located between the cross-bars or yokes G2 thereof. Said actuating device consists of a horizontal rock-shaft H, which is mounted in a vertical bearing-lug en. The inner end of said horizontal rockshaft is provided with a rigidly-attached depending rockarm Il', said rock-arm being located between the two cross-bars or yokes Grf2 of the two sets of plungers. The outer end of said rockshaft H is provided with two rigidly-attached oppositely-directed actuating-arms H2 H2, which are located laterally out of line with each other, as shown in Fig. 20, and are adapted to be engaged by verticallyreciprocating actuating-plungers l I, located one at each limit of travel of the carriage and eX- tending upwardly through openings in the frame-plate. Said arms are adapted to be forced upwardly by said plungers when the carriage is at the limit of its movement in either direction, and thereby rock the shaft Il, so as to throw the arm H against one of the plunger-yokes or cross-bars G2 and act through said plun gers to throw the associated iin gers upwardly into their gripping positions. Said actuating-plungers l are pivotally connected with the opposite ends of a verticallyoscillatory lever I', which is located beneath the frame-plate and is pivoted between its ends to a depending hanger a5, Fig. 5, on the frame plate. With this construction the plungers I are alternately thrown upwardly, so that cach will engage its arm H2 of the rock-shaft ll when the carriage is at the ad jacent limit of its movement. Said lever l' is for this purpose actuated by means of a cam-yoke l2, which is provided with a camstud i, which engages a cam-groove z" in a Cain-wheel I5, mounted on `the shaft C5, as clearly shown in Fig. 5. The cam-groove z" is formed to oscillate the lever I twice during each rotation of the cam, so that one of the plungers is thrown upwardly at each limit of the throw of the carriage to move the fingers into their locking positions.

The gripping-fingers are locked in their closed positions by means of locking devices made as follows: G3 Gg designate verticallyswinging latches, which are pivoted on the bearings cw, through which the plungers G G' extend, said latches swinging in vertical planes. Each of said latches is provided at its outer end with a right-angle lug g3, which rides upon an outwardly and downwardly in clined tooth g4 on the upper surface of the yoke or bar G2. Said tooth is provided at its inner end with an abrupt shoulder, which is so located when the yoke or bar and plungers connected therewith are forced inwardly to their full extent, whereby the fingers are raised, that the lug g3 of the latch drops into contact with said abrupt end face of the tooth g4, holds or locks said cross-bar or yoke and the plungers in their forwardmost posi tion, and therethrough locks the fingers in their closed positions. Means are provided for releasing said latches at the time the head is in position to deliver a set of can members to the heading and crimping mechanisms and after the heading operation has been performed, so as to permit said carriage to be retracted, while leaving the can members and heads engaged with the heading mechanism. Said means, as herein shown, are made as follows: The latches G'J are provided with laterally directed lugs or pins G4, each of which when the head has reached eitherlimit of its movement is located over one of a pair of vertically-reciprocating plungers J, which extend upwardly through the frameplate of the machine. Said plungers J are pivoted at their lower ends to the opposite ends of a vertically-oscillatory lever J Said lever J is pivoted between its ends to a depending lug al on the frame-plate, as shown in Fig. 4, and said lever is oscillated by means of a camyoke J2, which is pivoted at its upper end to the lever and is provided with a cam-study', which engages a cam-groove j of a cam J3, afiixed to the rotative shaft C5. Said camgroove is so formed as to oscillate the lever J on its axis twice during each rotation of the cam, so that at each limit of the movement of the carriage one of the pins is raised to lift one of the latches Gi3 out of engagement with the tooth of the associated yoke or cross-bar and thereby release the connected plungers in a manner to allow the engaging lingers to drop downwardly by gravity, as shown in Fig. 4.

In order to insure that the can members will be retained in the recesses of the head and side plates thereof when delivered thereto by the chute and before the fingers fully close IOC IIO

thereon, we have provided means for partially elevating the outer ends of said fingers just prior to the delivery of the cans to the head, said means being made as follows: K K designate two inclined or cam projections which extend upwardly from the upper face of the frame-plate, as shown in Figs. 3, 4, and 5, and are located just inside the openings in the frameplate through which extend the plungers I, which actuate the rock-shaft H. Said projections K, Figs. 5, and 9, are provided with inwardly and downwardly inclined faces lo and horizontal faces 7c. Said projections are located out of line with respect to leach other, so as to bring the same in alinement with the laterally-offset oppositely-directed arms H2 of the finger-actuating rockshaft. With this construction just before the-head is moved into position to receive one of the sets of can heads and, bodies the rearwardly-directed arm H2 of the rock-shaft H with respect to the direction of movement of the carriage strikes the inclined face 7c of the adjacent cam projection and rides upwardly thereon and thereby rocks said shaft. The angular movement of said rock-shaft acts through the plungers to gradually raise the fingers until they are brought to the position shown in Fig. 3. The arms H2 are engaged with the horizontal parts 7c' of the cam 'projections slightly before the head is moved into position to receive a set of can members. Each of the arms H2 is located over one of the actuating-plungersl when the carriage` and head are arrested in position for one end of the head to receive a set of can members from the chute and for the other end of the head to deliver another set to the heading and crimping mechanism, and the parts are so timed that when a set of can'members is received by one end of said head one of the plungers I rises and fully closes the fingers associatedwith said end of the head.

Next describing the mechanism for placing the can-heads on the bodies delivered thereto by thek reciprocating head-described and' for crimping or folding the anges' of the canheads on the bodies, said mechanism is made as follows: The machine is provided with two-heading and crimping mechanisms located on each side of the frame-plate in alinement with eachother and to which the sets of can members are alternately delivered as the carriage is arrested at each limit of its throw.

Each heading mechanism consists of two endwise-movable non-rotative plungers L L,

' which are mounted in hollow spindles M M,

which are rotary and `constitute 'parts of the crimping mechanism, as will hereinafter more fully appear. Said spindles M are mounted in suitable bearings N, having fianged bases, which have sliding engagement with longitudinal ways or guides in the frame-plate, as more clearly shown in Fig. 4. Said plungers are arranged in alinement with each other and are provided at their inner' or adjacent ends with rigidly-attached disks or plates L', which are adapted to engage the flat faces of the can -heads and through endwise movement of the plungers to force said heads over the ends of the can-bodies. Z Z, Fig. l5, designate collars which are rigid on said plungers L, said colla-rs constituting shoulders,'be tween .which and the plates L are interposed thrust-plates L2, which are'rotative; on the hubs of said plunger-plates, as shown in Figs. l5 and 16. Said plunger and thrust-plates are provided in their adjacent Vfaceswith opposing grooves forming runways for' antifriction-rollers Z2, interposed between said plates.

The outer ends of said plungers L are connected with cam-yokes L3 L3, which yokes are provided with lateral studs Zn, which engage camgrooves o in horizontal cam-disks O.

Said cam-disks are mounted on vertical shafts v O', which extend upwardly through the frame-plate of the machine and have bearing at their lower ends in bearings d8 and at their upper ends in bearing-brackets a9, as'more clearly shown in Figs. land 2. The shafts O' at'each side of the machine are rotated through the medium of horizontal gearwheels O2 on said shafts and a central gearwheel O4, which is fixed to a vertical shaft 05.

The shafts O5 are mounted in the bearings a3,

formed on the `bearings for the shaft C5, as shown in Fig. 1, andare rotated from "said shaft'05 through the medium of bevel gearpinions O6 Ca on the shafts O5 and Orespectively. With this construction it will be' seen that during each rotation of the cams O the plunger-plates are thrust inwardly toward each other and against a set of can-heads which have been delivered therebetween by the head D, said plates acting onthe" canheads to force the same over the ends ofthe can-bodies.

. Desir-ably one vof the-cam-yokes L3 at each side of vthe'machine is yieldingly connected with its plunger. .For this purpose the sockets in the yieldingly-connected yokes which'receivetthe plun gers are elongated, and a coiled spring Z4 (see left-hand side of Fig. v6) is inserted between the bottom of said socket and the end of the plungers. The plungers are inovabl'y connected with said yokes by'mea'ns of cross-pins Z5, which extend transversely through the plungers and engage grooves Z in said camyokes in the manner shown'in Fig. 6.'

- The spindles M are provided inside their bearings N with rigidly-attached short sleeves or collars M', provided with radial vertical flanges M2, which constitute thefcrimpingheads. v y

P P, Figs. l'and 16, designate a plurality of angular arms, the members p p of which are disposed at right angles' to each other. Said arms are pivoted near their angles to and between radially directed lugs m ony said heads M2 by means of kpivotpins m'. The outer members p of the arms of each crimp- IOO ing-head extend laterally toward the assof ciated crimping-head, while the members p of each crimping-head extend radially toward each other. Rotatively mounted on the outer ends of said members 17 are crimping-rollers P', which rotate on the axis of said members p. Said members p of the arms are held normally divergent with respect to each other by means of springs p2, interposed between the heads M2 and the inner members p of said arms. The inner members p' of said arms are provided with adjustable stopscrews p3, the inner ends of which screws are adapted to bear against the thrust-plate L2, as shown in Fig. 1G, when the crimping devices are lnoved inwardly to engage the rollers P' with the can-head flanges.

Reciprocal motion is imparted to the standi ards N, in which the spindles M have bearing,

through the medium of cam-yokes Q, which are secured at their inner ends to said reciprocating bearings and are provided with camstuds q, adapted to engage cam-grooves q in horizontal cam-disks Q, afli'xed to the shafts O below the cams O, as shown in Fig. 2. Rotative movement is imparted to the spindles M through the medium of pulleys M3, affixed to said spindles between the'members of the bearings N. Said pulleys are driven contin nously by belts M4. As shown, said belts M4 pass beneath said pulleys M3 and over intermediate idlers R, one located between each pair of standards N and mounted in suitable bearings R on the upper face of the frame plate of the machine. to be carried upwardly over a driving-pulley located above the machine, but not herein shown. Said pulley or idler Ris made wider than the pulleys M3 M3, so as to permit the belt to shift laterally thereon as the standards carrying the crimping mechanisms are reciprocated to and fro.

The operation of the heading and crimping mechanism described is as follows: The camgrooves 0 of the cam-disks O are so disposed asto thrust the plungers L inwardly to engage the disks L thereof with the can-heads as soon as the movement of the head D of the carriage has been arrested with the set of can members centered with respect to the heading and crimping mechanism. By this movement of the disks the can-heads are forced upon the body. Said can-heads are forced upon the can-bodies while said heads are gripped by the fingers D2 D4, the yielding engagement of the fingers D4 with the heads due to the backingsprings g engaging the plungers G associated with said iin gers D4 permitting such operation withoutinjnry to the can-heads. Immediately after the heads are thrust upon the body the grippingdingers D2 D`l are released from the can heads and body, as shown in Figs. 4 and 5, and the carriage C is retracted, carrying with it the head D. After the can-heads have been forced upon the body by the means described and the carriage retracted from the heading and crimping mechanisms the standards N are forced inwardly toward the can through Said belts are adapted the action of the cams Q and move the crimpin g-rollers toward the cans. As the crimpingrollers approach the flanges of the can-head they are disposed slightly divergently with respect to each other and strike the widest parts of the flanges (when the fianges are fiaring, as shown in Fig. 15) before the rollers are moved inwardly by engagement of the contact-screws p with the thrust-plates L2 on the plungers L. Thereafter the contact-screws engage said plates L2 and swing the arms P on their pivots and therethrough swing the contact-faces of the rollers from the positions shown in Fig. 15 to that shown in Fig. 1G. During said operation of the crimping-rollers the spindles M are being rapidly rotated through the medium of their pulleys, thereby causing the crimping-rcllers to revolve rapidly in contact with the can-head Iianges. The movement imparted to the crimping-rollers is therefore a combined longitudinal rotative and angular movement, and the head-flanges are thereby forced down tightly on the body throughout their width. rlhe final pressure exerted on the flanges is by the inner ends of the rollers on the inner margin of the flanges.

/As this pressure takes place while the rollers are moving bodily inwardly, the operation is similar to a spinning operation.

The plunger-plates remain in contact with the can-heads during the crimping operation and constitute abutments or anvils against which the rollers act when the can-heads are of the form shown in Fig. 15, wherein the plungeihplates lit within the recesses of said heads. Then the outer faces of the heads are flat, the plungenplates engage said flat faces of the heads. After the joints between said head-fiangcs and the body have been formed in the manner described the cams O and Q act through their connections with the plungers L and the bearings for the crimpingheads to quickly withdraw the crimping-rolls and the plunger-plates from the cans, thereby allowing the cans to fall on the carriage-runway, which is inclined to direct the cans from the machine Means are provided for truing the cans just before the heads are forced thereon and during the time said cans are engaged with the carrying-head D, so as to insure that the canheads will properly register with ends of the can-bodies. Said truing operation is made desirable by reason of the fact that the canbodies are likely to become distorted while passing through the chute or when delivered from the chute to the heading and crimping mechanisms. The truing devices are espe cially useful when operating with can-l1eads the flanges of which do not iiare, but are disposed generally at right angles to the bodies of the heads, as it is necessary with this type of head to observe considerable accuracy in applying the same to the canbodies. Said truing means for each of the heading and crimping mechanisms consists of a wing or plate S, having a curved engaging face which IIO is formed on the same radius as the recesses d of the head and the curved inner surfaces of the fingers D2. The wings or plates S yare made of such length as to fill the spaces between the upper ends of the fingers D2 Dfand the head, so that the can bodies will be embraced throughout their entire circumferen ce. As herein shown, said truing-plate is made of the same length as the gripping-fingers, each embracing one-fourth. part of a circle.

The truing-plates are act ualed by the following mechanism: VS' S designate arms, which are rigidly affixed to horizontal rockshafts S2,'Which are mountedin the upper ends of vertical supports S3, attached to the side of the frame-plate. As herein shown, said arms `are affixed to the shafts bymeans of set-screws s,which extend through hubs on said arms and impinge upon said shafts. The-inner ends of said arms are pivoted to the truing-plates, each plate being provided on :its upper face with laterally-separated lugs s', between which the. inner ends of the arms fit and with which they are connected by means of pivot-pins s2. The connections thus provided are sufficiently free to permit the plates to adjust themselves to the-can-bodies when pressed lhereagainst, while being rigid enough to hold the plates fromdropping downwardly when retracted. Said plates are swung inwardly against the can-bodies at the proper time by means of arms s4, which are rigidly attached at their upper ends to the shafts s2 and are connected at their lower ends .with cam-yokes S5. Said cam-yokes are Lpro-l vided with cam-studs s4,.which engage camgrooves S5 in the opposite sides of a cam SG, affixed to the shaft C5. The cam-grooves s are4 so disposed with respect to each other` that in each rotation of the cam the truing plates or Wings are alternately actuated.'

v.The operation of the machine describedwill be obvious from the foregoing, but may be brieiiy recapitulated as follows: The can heads and bodies are fed set by setto theA chute E. During a portion ofthe operation of the machine the head D is located centrally of kits path of travel with the central part thereof beneath the chute, so that at this time the can-body and the heads rest upon the upper margins of the Web D/ and the lside fram es D3. During the` time the carriage occupies such central position the camstud c2 of the cam-yoke C2, by which the carriage is given f motion, is traversing the concentric portion l of the cam-groove c4. tion of the cam c4 the cam-stud c2 entersA the eccentric portion 2 of the groove, and while vsaid stud is passing through this portion of the groove the carriage moves toward one of the heading 'and crimping mechanisms to carry thereto a set of can members which had f previously been delivered to one end of the carriage. r The cam-stud cs after traversing the part 2 of the cam-groove c4 enters the concentric part 3 of the cam-groove, and during the traverse of the cam-stud through this In the kfurther rotapart of the groove the carriage and head are brought to a rest in position to deliverthe tion of travel'is brought toregister with thechute E one ofthe actuating-arms H2 of the rock-shaft H is b ought into contact with one of the cam projections K, which causes the fingers DL D2 to be thrown upwardly into the position indicated in Fig. 3 to prevent a set of can members from falling out of the head after being delivered thereto. Thereafter a set of can members is delivered to this end of the carriage, and one of the plunges I is elevated by the mechanism described and acts on its associated rock-shaft-actuating arm H2 to fully close the fingers D2 D4, the latch GS-acting to lock said plungers in their closed position-s. After the forward end of the carriage-head reaches one of the heading and crimping mechanisms and is centered with respect thereto the associated truingplate is depressed `to true the can-body, and thereafter the plunger-plates of the heading mechanism are advanced by their cams O and engageA the can-heads and force the same over the ends of the canbody while the fingers .D2 D4 are vyet engaged therewith. After said plunger-plates have forced said can-heads on lthe can-body oneof the plungers J is elevated yinto contact with the pinG4 ofthe latch G3, :thereby serving to release said latch from' the associated plunger cross-bar or yoke-and y.permit the fingers D2 D4 associated with the can members just delivered to the heading Land crimping mechanism to be released and to fall downwardly intoy the position shown in the Figs. 4 and 5.

The truing operation, the head-ing operation, and the releasing of the fingers occur while the cam-stud c3 is through the part 3 of said groove enters an eccentric portion 4 thereof, made like the part 2 of said groove, which'causes said carriage to' be sharplyretracted-to its central position be neath the chute E. Said carriage is held in A this position While vthe cam-stud c3 travels the concentric part 5 of the cam groove (which corresponds with the part l, before described) and until said cam-stud enters the eccentric part 6 of said groove. The passage of said cam-stud through the'said eccentric part 6 causes the carriage to be moved to the opposite heading and crimping mechanism forthe purpose of delivering the set of can members carried by the forward end of the head to said mechanism. The camstud c2 passes from said eccentric portion 6 of the camgroove ,to the concentric portion 7, and while traversing the latter port-ion the trning mechanism adjacent to said head is operated, the fingers released, and the plunger-plates moved inwardly to force the can-headsupon the IOO -passing through the concentric 'part 3 of the v .cam-groove et The cam-stud after passing ing-fingers pivoted to the heads for holding the can members in said recesses, means for Vclosing'said fingers after a set of can members has beendelivered to said head, and means for opening the fingers after a set of can membershas been delivered to one of said mechanisms.
