:MACHINE FOR UNITING CAN BODIES AND HEADS.

To all whom it may concern Be it known that I, JAMEs A. GRAY, a

citizenof the United States, residing at San Francisco, California, have invented certain new and usefullmprovements in Machines for Uniting Can Bodies and Heads of which the following is a specification.

My invention relates to machines for male ing cans, and more particularly to that portion of such machines employed for seaming thecan head to the can, and in the relation of such seaming mechanism to the other parts of the machine.

The invention consists in the features and combination and arrangement of parts here inafter described and particularly set forth in the appended claims.

In the accompanying drawings-Figure 1 is afront view of a machine-for making cans or attachingcan heads to the bodies, and embodyingmy present invention; Fig. 2 is an end elevation of such machine looking'from the right of Fig; 1; Fig. 3 is a plan view of the feeding mechanism for can bodies; 'Fig. 4 is a sectional view of the stamping head or crimping device wherein the flange is formed at the top edge ofthe can; Fig. 5 is a view similar to Fig. tof another stamping head for bending the flange of the headand body downwardly and outwardly; Fig. 6 is a view similar to Fig. 5 of another stamping head for performing the nextstep in the operation of forming the joint between the head and body; Fig. 7 is a side elevation of the seaming steps in the operation.

In these drawings, 1 are the side frames of the machine connected by the cross plate or table 2, and having journaled at their.

upper parts adrive shaft 3 carrying a gear wheel 4: through which power is communicated to the machine. In the side frames, at cross head 5 is guided to move vertically, said cross headbeing operated from eccentrics or cams at 6 on the drive shaft 3, and bein connected by eccentric rods 7 with c v v the cross head. This cross head carries a plurality of, stamping heads for performdiiferentsteps in the operation of uniting the can members, as will be hereinafter described, these stamping heads being indicated at a, b, c and d. At the lower part of the frame a shaft 8 is mounted carrying 5 cams, as 9, 10 and 11, forgiving vertical head; Fig. 8 shows .the different Specification of Reissued Letters Patent. R i d 2,1 5

movement through rods 12, to vertically movable plungers for elevating the can bodies indicated at 13, to the several stamping heads. This shaft 8 is driven froma shaft 14 through an inclinedshaft 15 and bevel gearing at the upper and lower portions thereof, the shaft 14 being driven from the main gear 4 through a gear 16. The can bodies to be united to the heads are fed along a table or way 17,.suitably supported in the frame, by an endless chain 18 having jaws or projections 19 to grasp the can bodies, said chain passing around wheels 20 at opposite ends of the machine. One of these wheels is on a shaft 21 extending vertically and operated by at Geneva movement consisting of the wheel 22 thereon having arms or ways 23 extending radially and engaged by a pin or roller 24 on an arm 25 mounted on the vertical shaft 26, which is geared to the drive shaft 3 by the bevel gearing 27 By this Geneva movement the feed chain for the 'can is moved step by step, and at each movement a can is brought beneath the first stamping head a.. This stamping head descends, and flares outwardly theupper edge of the can body, as shown in Fig. 8 at of. For this purpose the stamping head is provided with an inner member 28 having an inclined edge 29 and a depending flange 30, the said inner member coiiperating with jaws of segmental form shown at31 within the main outer ring of the stamping head, and supported by the shoulder 32 on the said ring or head. These jaws 31 have inclines at 33, 34, so that, as thestamping head comes down, the jaws 31, by striking upon the fixed wall 35 of the way or channel 36 (see Fig. 2) along which the cans pass, will be forced inwardly toward each other by the continued movement of the main body of the stamping head, which causes the inclines 33 and 3 1 to press thereon and move the said jaws inwardly. These jaws 31 have inclined bearing surfaces at 37 and these, cooperating with the inclines 29 and the flange 30 on the inner member 28, will cause the upper edge of the can to be flared outwardly.

When the stamping head rises, springs 38 connected with the ring 39 which, in turn,

is connected with the jaws 31, will lift the said jaws and they will be returned to their outer positionsby the inclines 40 on the inner member 28.

The next forward step movement of the feed chain will cause the can with its flaredmpper edge to be brought beneath the stamping head I), and at this point a can head will be fed'into position above the can body,. and the'actions indicated at b in Fig. 8 will take place; thatis,

the can head will have its flange bent into looking engagement with the flange of the can body, but the position of the parts will be flared upwardly. As'this action and the means for performing the same form in themselves no novel part of the present iii-- vention, I have not shown it in detail herein. But means for feeding the can head into position and bending its flange and the flange of the can head into interlockingengagement, form a part of the invention claimed herein, 1n certaln new combinations hereinafter pointed out. In my Patent N o.

994356, granted June 6, 1911, for assembling mechanisms for can bodies and heads, I have set forth mechanism for feeding the can head over the body of the can below the stamping head I), and for forming the body and as shown at b in Fig. 8. The next forward stepmovement of the feed }chain will carry the can, with its united head, beneath the'stam'ping head 0, and this stamping head, as shown in Fig. 5, by means of the edges 41 and 42 on the segmental jaws 43 and inner member 44, respectively,

' willturn the united flanges of the head and turn the united flanges of the head and body body into the positionshown at c' in Fig. 8. For this action the can body is lifted to a point within the stampmg head a by means of the cam 10, and a suitable plunger operated thereby, asindicated in Fig. 1. After le'aving'the stampinghead'c, the can body,

with its head, is conveyed to the stampinghead (Z, which, as shown in Fig. 6, is composed of inner and outer members which into the position shown at cl in Fig. 8. The parts are now ready to be sub3ected to the action of the rotary seamlcompressing means comprising a rotary .head. This head is shown at the right of Fig.1, and in Fig. 7, and it comprises an inner member or ring 4-5 attached to a vertical shaft 26*. Rotatably mounted on said shaft is a cross bar or head 46 having pivotally mounted thereon arms 47 carrying seam compressing wheels 48 and carrying also at their upper ends points or bearings 49. A'sleeve 55 is connected to said head at its upper end, and

said sleeve carries a pinion 55 so that when the pinion is rotated by the gear 56 on the shaft 26 of the Geneva movement, the sleeve and'cross head will also be rotated. A second sleeve 55 is loosely mounted on the sleeve .55, and this sleeve 55. carries'at'its lower end a cone member 50 and at its -'-upper end a flange 54. The cone member is engaged by the points 49. This cone member is adapted to be moved vertically noon the .bead ofthe can by a collar 51 located between the cone and flange 54, said collar being connected with rods 52 guided in the frame, and operated in any suitable manner from a cam 53 on the drive shaft 3. The center member 45 is provided with a flange 45""directly-opposite the grooves 48 in the seam compressing wheels. After the can, withits attached head, leaves the stamping head (i, it arrives over a vertically movable plunger .pperated from the cam '11, and it is raised by this'plunger so that the recessed head of the can will be lifted in register with the center 15, and this center will enter the recess in the can head, so that its flange 45 will lie in the same plane with the bead or united flanges ofthe can and head. The rotation of the cross head 46 through the gear 55 will now cause the seam compressing wheels to seam the bead or flange tightly against the side of the canbody, pressing all of the interlocking flanges closely together, so that a perfectly. tight joint will be formed to render unnecessary tlf use-of solder. As the seam compressing proceeds, the cone 50 is depressed by the operation of the rods and the cam 53 above described-so that theupper ends of the levers 47 will be separated, and the wheels will thus be pressed with a gradual movement and increasingpressure or the. interlocked flanges. After the seam compressing actionhasbeen completed, the cam '11 lowers the plunger, together with the can, and the next movement of the feed mechanism conveys the can away from the seaming headf I claim as my inven o .1. In combination in a machine for makingcans, a series of reciprocating non-rotary seaming dies arranged in line, a conveyer having a step by step movement for moving the. can body with its head from one set of dies toanother, and rotary seam compressing means in line with the series of seaming dies and to which the conveying means moves the can body and its attached head,
