CAN-MAKING MAcHInE;
My invention relates to can making ma-' chines and is particularly directed to a, ma chine for attaching the bottoms to metal, preferably tin, cans, and curling the edge of the metal forming the top of the can.
My invention will be better understood by reading the following description taken in connection with the accompanyingdrawings, in-whi h 1, is a toplplan View of a portion of th machine showing/my invention applied thereto;
Fig. 2 is a side elevation of the portion of the: machine shown in Fig. 1 and,
Fig, 3 is an, end elevation of the curling chuck'on-a scale largergthan shown in Figs. 1 and 2.
Myinvention consists in the addition of an attachment to. a. standard can-forming machine, such as that known as a horizontal double-seamer and the combination of elements resulting from such addition, the machine acting to perform the specific functions of: double seaming the bottoms and curling jtheltops ofthe cans. In illustrating my invention. I have shown only-such parts'of the I standard I trate theapplication of my improvements thereto;
' Referring to the drawings, the parts of the standard machine comprise? a feeding Wheel 1v mounted on a shaft 2 and having grooves or recesses} therein for feeding-cans at in :tervals to theidouble seaming and curling mechanism.- The details of thedouble-seaming mechanism are not illustrated because persethey donot; constitute any part of my invention The double-seaming mechanism constitutes two operating rolls 4 and 5. T eroll 4- p rforms a cert in. pa t of the opera ion of doubler-seaming and-the ro 5 cc'nnpl'ete v such operation. The rolls 4t and 5 are carried by the frame of the-machine and are supported in suitable bearings therein. A shaft 6 is also supported byv the frame-of the; machine and carries, two cams 7 and 8. F astenedto the cam 7: is a rod 9, one endof which is. pivotally connected-withan arm 10 loose y mo nted on the sha T ea m 10 carriesia pawl 11 which engages the teeth of the ratchet, whee/112 and r ta s. the shaft, 2 vand'thermvit the feed-Wheel l which delivers the caneto the, double-seaming. rolls.

with a-gear 14 on a shaft 15. The gear-l4 is 'frictionally connected withthe shaft 15' by means of the fiber collars 16 and 17, the fric tion of which is controlled by a nut 18 screw threaded onto the shaft 15, as shown in Fig. 1. Shaft 15 carries a curling. chuck 19 and when the shaft 15 is'rotated the chuck l9 rotates therewith;
The chuck 19 is composed of a frame which, are'mounted; three members 21; each carrying a grooved wheel 22 attached to rotate in the respective members- 21w The grooves in the wheels 22 are arrangedon a circle having a center at the center (if-the shaft 15. The diameterof this circle is. equal tothat of thecan to'be curledyfor a reason which will appear-laten- The ;memb.ers 21 are 'movably mounted in the frameHZO and have a neck portion 23 projecting-through the frame and a ring 24' is attached to the necks 2,3, as shownin Fig. 1. Compressionsprings, 2,5 are-seated at; one endin the frame 20 and'have their other ends placed against the ring 24L tending toimove the. ring and the -members 21qwhiclnare attached thereto to the right, as viewed in Fig.61.
This action of the springs thereforeis to, re-

Sinee the canyisrotated by the double-l seamer, I: have chosen to. arrest w tary movement-between the can nd? the the curling chuck is arrestec.
the curling operation. The means for a1- resting the rotation of the curling chuck comprises the cam 7, and arm 35 having a roller 36 engaging the cam 7. The arm 35 is rigidly attached to a rod 37 Which carries a pawl 38 at the other end and which pawl 38 is adapted to engage ratchet teeth 39 on the frame 20 of the curling chuck. When the roller 36 engages the proper portion of the cam 7 the pawl 38 is thrown into engagement with a tooth 39and the rotation of The arresting of the rotation of the chuck is possible be cause of the frictional engagement between the gear 14: and the shaftls). The rotation of the chuck is arrested for only a short time because it requires only one or two revolutions of the can to effect the curling of the top. The cam 7 is therefore so designed that the pawl 38 will be released from the teeth 39 immediately upon the completion of the curling operation, and by an inspecof 'Fig. 2 it will be noted" that the raised portion 40 of the cam 7 is a very small part of the periphery thereof.
- In operation a can is fed by the wheel 1 into position for operation by the first seaming r0114. It is then moved into position for the operation of the second seaming roll and the cams '7 and 8 are so designed that near the end of the double-seaming operation the chuck having the curling rolls thereon is moved toward the'end of the can while the can is rotating and the rotation of the chuck is then arrested, whereupon the continued rotation of the can causes the edge of the metal to be curled, as above explained. The cams automaticallyrelease the curling rolls from the end of the can and permit the sameto again rotate until the next can is in position and ready for the curling operation.
7 All of the above operations take place rapidly and are'entirely automatic and the simplicity of the device enables a largejproduction to be secured from the machine without any substantial wear upon any 0 the active parts, thus insuring a long life and the efficient operation of the machine. 7 "I have illustrated the preferred form of my invention and the form which has been tried and found commercially satisfactory; and while I prefer the constructionshown,
'I wish to be understood that I am not limit-ed to the exact arrangement, as many detail changes may be made without departing from the spirit of my invention.
