LEEA C. SHARP, 0F PLATTSMOUTH, NEBRASKA., ASSIGNOR TO AMERICAN CAN COM- v PANY, OF NEW YORK, N. YL', A CORPORATION OF NEW JERSEY.

COMBINED ELANGING AND HEADING MACHINE.

Specification of Letters Patent. Patented Steph 28, 19,15.

Application filed December 4, 1909. Serial No. 531,442.

To all whom t may concern Be it known that I', LEE C. SHARP, a citizen of the United States, and a resident of Plattsmouth, inthe county of Cass and State of Nebraska, have invented certain new and useful Improvements in Combined Flanging and Heading Machines, of which the followinr is a specification.

lfly invention relates to the manufacture of sheet-metal ware, and more particularly to machines for flanging can-bodies' and securing the heads thereon by double-seaming operations.

It is the object of my invention to provide a combined langing and heading machine to which the heads and plain bodies may be fed, the 'bodies beingy received by a carrierwh'e'el which is intermittently advanced 'toy ings, in which- Figure 1 is a longitudinal section of the machine, Fig. 2 is an end elevation'thereof, Fig. 3 is a transverse vertical l section on the plane of the line '.fc-xof Fig. 1, Figjll is 'a detail plan view of one of the multiple cams for 'reciprocatingthe chuck-spindles, Fig. 5 isa detail side view of apart of the carrier-wheel, Fig. 6 is an angular projection of a art of the carrier-wheel, Fig."7 isy a detail diagrammatic viewv` illustrating the Hanging operation, 1andv Figs.l 8,' 9 'and 10 are viewsshowing dili'er'ent vstages of the heading' or seaming operation.

In each of Figs-1, gand', the lower portion of the machine iframe or base is vbroken `vaway, in FigsfQ' and 3r portions of the Lfeedchutes o'r runways foi-fthe heads Vand canbodies are b'rokeniaway, and in Fig. 1 the planeof 'section ismainlythat of the line of FigjQ, but through a part" of 'the carrier-wheel the plane o'f section is deflect- Vedfto that of the' lin'e' e-s of Fig'i.

vIn the construction shown, 'I lprovide a frame eonsi'stin'gef a suitable base .l upon which at the ends thereof are secured the bearing- heads 2 and 3. The main'driving shaft 4 is journaled in suitable bearings arranged at the side of the base, and onr one end of the said shaft is carried the main driving pulleyr 5. ln the lower portions of the heads 2 and 3 is journaled the shaft G and on said shaft between the 'heads is secured the carrier-wheel ".7. Between' the bearings of the shaft 6 in the head 2 a ratchet-wheel 8 is secured upon the shaft, and adjoining said ratchet-wheel the lever 9 is pivotally mounted upon the shaft. rlChe upper end of. the lever carries a suitable ypawl 10 adapted to engage theteeth of the ratchet-wheel, and the' lower end extends through an opening in the side of the base 1 and has a roller which engages a suitable cam 11 carried on the main driving shaft, theroller being held in engagement with the cam by the weight of the lever. The said ycam is adapted to impart an oscillating movement to the lever which thus', bythe engagement of the pawl 10 with the ratchetwheel, intermittently'advances 'the shaft and carrier-wheel by amounts proportional to the spacing of the ratchet teeth. In the rim ofthe carrier-wheel 7 are formed a number of semi-cylindrical recesses or pockets which are equidistantly spaced from each other and are the same in number as the teeth of the ratchet-wheel S, so that as the shaft is advanced by the ratchet-wheelv the pockets successively occupy like positions. At the front 'side of the machine is an inclined feedchute or runway 12in which are placed the canebodies A to be operated upon, and which is so arranged that at each movement of the carrier-wheel. one of the pockets therein stops adjoining' the end of the chute so as to receive o'ne of the can-bodies therefrom.

In the'upper portions of the heads 2 and 3 are journaled six chuck-spindles 111 which are arranged at opposite sides of the carrierwlieel in pa'irs'of which each is a'lined with the longitudinal axis of one of the pockets ofthe wheel. 'On said chuck-spindles between the"bearings thereof in the heads 2 and 3 are secured pulleys 15 which are driven by means of belts 16 passing alternatelypbelow and over the same as shown in Figs.' 2 and 3,."an'd extending to `suitable driving pulleys arranged 'above the macl'iine.,r Gn the innerends ot the spindles are carried the chucltplates 1,.7 and en the outer vend portions of the spindles sleeves 18 areloosely mounted, being retained thereon by collars securedA at the ends of the spindles. rlhe said sleeves are connected by short links 19 with the upper ends of the levers 2O which are fulcrumed between lugs on the ends of the heads2 and 3 and extend in radially toward the shaft 6. At the inner ends of the said levers 20 are rollers which engageV the multiple. cams 2l. Said rollers are held in engagement with the cams by means of springs 22 which are connected with the levers near the lower ends thereof and extend in through openings in the ends of the heads 2 and 3 and are attached to suitable connecting-blocks 23 arrangedinside the heads, as shown in Fig. l, The cams 21 are formed upon hubs 2l which are pivotally mounted upon the ends of the shaft 6, being held thereon by plates 25, and from said hubsV arms 26 extend diagonally downward and at their ends carry rollers which engage the cams 27 secured on the main d riving shaft l.' rl`he rollers are held in engagement with said cams27 by means of the s rings 2S connected with thearms shown. rlhe cams 27 impart an intermittent hubs 24:, cams 2l, levers 20, links 19 and` vvsleeves 18, to the chuck-spindles which are the carrier-wheel. bodies 29 about the shaft 6 is such that the rollers move alternately from positions sub! stantially in radial alinement with the pockand wit lugs arranged on the Abase as oscillating motion to the arms 26, which movement is communicated through the thus given an intermittent longitudinal reciprocating movement.

0n the shaft 6 adjoining the ends of the hub of the carrier-wheel are pivotally mounted the sector-shaped bodies 29 from Ywhich the arms 30 extend diagonally downward and at their ends carry rollers which engage cams 31'secured on the main driving shaft. The rollers are held in engagement with said cams by springs 32 connected with the arms Yand the base as shown, and the cams are adapted to impart an intermittent oscillating movement to the sector-shaped bodies 29. The said bodies 29 carry radially extending shafts 33 which are adjustably secured therein by set-screws 34. At the outer ends of the shafts 33 are heads in `which are rotatablyv mounted the Hanging-rollers 35 and seaming-rollers 36, and the shafts are soV spaced that all of the rollers will be in substantially the same relation to the pockets of rThe movement of the ets of the carrier-wheel to positions intermediate between'the pockets. The side portions of the carrier-wheel rim are of less thickness than the depth of the pockets, so that at the ends the pocketrecesses cut through said portions of the rim, as'shown in Figs. l. 2, 3, 5,' 6and 7.' Thus the end portions the can-bodies lying in the pack vin the said position.

the said can body is carried tothe first opery ating position between the chuckplates '17 carried by thefirst pair of spindles lll. The spindles are thenmoved inwardly to cause the chuck-plates to pass into the4 ends-of the body. The members 29V are then rotated upon the shaft 6 so as to bring they flangingrollers 35 to the operating position shown in Figs. 3 and" 7, at which said rollers engage the can-body and raise it up into engagement with the revolving chuckplates of which the said first pair are so formed vas to coperate with the flanging rollers35 to flange the body while it is'held and revolved The members 29V are then rotated uponthe shaft 6 to carry the rollers to the positions intermediate between the pockets and thus disengage them from the can-bodies, the chuck-spindles are moved to withdraw the chuck-platesfrom the canbody, and the carrier-wheel is then advanced to carry the can-body to the next operating position between the next pair of chuckplates and spindles. During the said movement a can-head B is dropped into the groove l0 of the pocket, adjoining the end of the flanged body, the head bei'ngvcentered with the body by said ygroove as shown in Fig. 8. The heads are discharged from the chute or runway 37 at a position intermediate Vbetween the first and second operating positions and rest upon the rim of the carrier-wheel between the pockets at said first and second operating positions, being held in place laterally b v portions-of the chute. As the carrier-wheel is movedforwardly aV pocket passes beneath the Yhead which Vthen drops into the groove-40. ln'the 'construction shown in the drawings a head is apbody, after which the seaming roller 36 is moved to operating position and engages the Vhead to perform the first part of the seaming operation. The movement of thecan to the third loperatingpositionor second seam:-. ing position, and thev performance of the second part of` theseamingjoperation, are

made in a manne-'r similar to those for the first part of the seaming operation. The exact form of seam producedv and the form of the chuck-plates and seaming rollers for the production of the seam, are immaterial to my invention and may be varied asl desired. One form of seam which the machine is adapted to producev is shown,` in. Figs. 9 and lO, the seam being partially and entirely completedA in the respective figures. Subsequent movements of the carrier-wheel bring the canv to a. position such that it is discharged by gravity from the carrier-wheel pocket into the discharge-chute 38 which is arranged as shown. Suitable guide bars 39 are extended over the carrier-wheel from the body-chute l2 to the discharge-chute 38, and serve to prevent the cans being thrown out or' the pockets when engaged by the Hanging. and seaming rollers in passing from one operating position to another, but said guide-bars are spaced from the carrier-wheel suliiciently to permit the cans to be raised slightly out of the pockets in passing over the rollers.

It will be obvious that, as the various operations are performed simultaneously, one of the cans will be completed at each movement o' the carrier-wheel; and that the Hanging-rollers and seaming rollers, by engaging the cans from the inside of the carrier-wheel rim, tend to lift the cans out of the pockets and thus avoid any distortion which would result from the engagement of said rollers with the cans from a direction other than one tending to raise them out of the pockets.

New, having described my invention, what l claim and desire to secure by Letters Patent is:
