T all whom it may concern. Be it known that 1, JOHN F. Wins, a cit zen of the United States, residing at Chlcago, in the county of Cook, State of Illinois, have invented certain new and useful Imrovemcnts in Can-Closing Machines, of

which the following is a description, refermechanical means for feeding a can end from a stack underneath a seaming head, whereby the same is placed for attachment to the can body.

A further object of the invention is to provide means for rendering said feedingin means ineffective, except when a can body is underneath the seaming head.

These and other objects will in part he obvious, and will in part be hereinafter more fully describes. In the drawings which show by way of illustration one embodiment of the invention,Figure1 is a; side view of a closing machine .having my improvements applied thereto; Fig. 2 is a plan view of the sup porting plate for the stack of can ends, and the devices for operating the pusher to feed in the can ends; Fig. 3 is a similar plan View with the devices for operating the pusher broken away, and the controlling means for rendering the feeding-in device ineffective, shown in topv plan; Fig. 4 is adetail View, showing the stack holder and the finger for rendering the pusher inefiective; fig. 5 is a sectional view on',-the line 5 -5 of Fig. 4:; Fig. 6'is an enlarged view in side elevation, showing the controlling device for the feed- "ingin mechanism, with the parts in position to render the feed efiective; Fig. 7 is a similar view with the parts in position to render the feed ineiicctiveg and Fig. 8 1s a detail showing a modified construction of on a can end or cover, so as to form a double seam. The seaming head 2 is mounted on a shaft 3, which is rotated by a bevel gear connection i from a cross shaft 5, which in turn is operated from the main shaft of the machine. This seaming head. is moved up and down by a lever 6.

The can bodies which. are to'be closed are mounted on a support 7, and are fed along the same by a drum feed 8, which consists of a drum having a thread wound thereon, which thread extends above the support and engages the lower ends of the' can bodies. The filled can bodies are carried by means I of this feed underneath the seaming head, and the seaming head is lowered, so as to bring the seaming rolls into proper position to act upon the cover or end to secure the same to the can body.

Extending underneath the seaming head is a supporting and center'in' plate 9, which is mounted to move up and down in a bracket 10 secured to the frame 1 of the machine. The supporting and centering plate is attached toarod ll,which is in turn con nected to a lug on the lever 6 As the seammg head moves up and down, this support ing and centering plate will move 11 and down with the seaming head. Said p ate is positioned a suiiicient distance below the seeming head so as to allow the seaming head to rotate and the seamin rolls to be brought into contact with the ange on the can end to roll the same into a double seam. Centrally oi the supporting plate is an.

opening 12, which extends over the can body and serves to center the same underneath the seaming head. Mounted on the supporting plate 9 is a holder 13 for a stack of can. ends. Said holder consists of a base plate 14, and a series of rods 15, which hold the can ends stacked one above the other.

A pusher l6 slides through a suitable recess underneath the base 14, and is adapted to engage the lower can end in the stack and carry the same along a guiding raceway to a supporting ledge 17,=surrounding the opening 12 and forming a seat for centering the can end underneath the seeming head. The cover rests on this supporting ledge, and as the plate 9 is moved downward, the cover will be carried on to the can body, and will be seated therein/by. the usual seating pad, after which it is engaged the chuck, so

taken from the stack 1 said finger istat the a, plunger .fore, that when as to hold the can body stationary while the seaming head rotates about the same to secure the can end on to the can body.

The pusher 16 is provided adjacent its 5 outer end'with a post 18. To the upper end of this post is pivoted a link 19, which is in turn pivoted to a rock lever 20 attached to the frame 1 of the machine. The other end of the rock lever 20 is connected to a.link.21, which in turn is pivoted 'to a stud 22 that is "radially-adjustablein a disk 23 mounted on a cross-shaft of the machine.

The link 19ispre'ferably made in sections, which'are connected together by a sleeve 24, so that the length of the link 19 may be varied to varythe workingpositionfof the feeding-in pusher. rying the disk 23 head, the rock lever 20 will be oscillated, and said lever through the link 19 Will reciprocatethe pusher so that a can end will be and placed on the supporting ledge at each reciprocation of the pusher. The stud 22 may be ad usted radially on the disk 23, so as to vary the stroke of the. pusher. By this adjustment and the' adjustment of the link 19, I am able to control the stroke of the pusher, so that can ends of difier'ent sizesmay be fed to the seaming headand properly posltioned centrallyund'erneath the same. WVith-jthe above mechanical means for feedingiilrthe can ends, it will be noted that a can endis fed Ito the saminghead for each reciprocation of the seaming head. In order-{to prevent" the feeding in of -can ends when there is no'can body-underneath thehead to receive the can end, l 'jh ave-provided a controlling means for rendering the feeding-in devices effective or ineffective, in accordance with whether can bodies are being fed to the seaming head. f Said controlling means, as herein shown, consists of a finger 25, which is mounted so as to, slide backand forth in a supporting-bracket 26 attached to the supporting plate 9; This finger projects throughthe base 14 into the stack. holder, so that the lower can end in a stack will rest-at one side on said finger. The finger is so dis 0 posed relative to t e pusher 16, that when inner end ofitsstroke, flasshown in Figs. i and 5, the can endswill raised so that the stack, and, there-, .igiegwhen. thetfinger is at the inner end of aidfeeding-in means will be er 2 5 is moved back and forth by 27, which is formed at its lower ,en'd with ih'uvertical portion 28,'and an inclined portibn 29. These parts 28 and 29 areadapted tovmove in an opening 30 in the: finger 25. It will readily be seen, therethis plunger is moved from the position shown in Fig. 5 to -its extremel As the cross shaft carrotates with the seaming l upper position, that the finger 25 will be withdrawn from the stack holder sufficiently to allow the stacked can ends to descend and ii the lowermost end to be placed in the path W of movement of the pusher. When the plunger is moved again to the position shown in Fig. 5, the finger will be moved into the stack holder. i

The inner end of the finger 25 is tapered 7.5- at 31, so as to aid in lifting the stack or passing underneath the lowermost end in, the stack. A plate 32 is secured to the u per face of the pusher 16. .on the side thereoFadjacent the finger 25, to aid in holding the stacked ends so that the finger 25 may be with"certainty moved underneath the sameto support the ends at one side thereof. The plunger 27, is provided with two spaced collars 33, which are fixed thereto. A 35 lever 34 is pivoted at one end to a bracket 35, and is formed with a ball collar 36 intermediate its ends, which rests between the fixed collars 33 on the plunger 27. 'he lever 3-Fat its outer end is pivpted at 3'1 99 to a'controlling pad 38. A weight 39 is se cured to the lever 34. It is obvious, how ever, that in place of said weight any-de sired means may be used for depressin the outier end of the lever 34. The contro ling pa filled can on thefeedingjdevice, whichis to be carried underneath 38 is positioned so as to extend over the b 0-0 device, as the forth, the can point within the path of-the controlling plllld 38, the next downward movement 0 seaming head, which: carries with it the supporting plate 9, the stack holder and the 9 feeding-in devices, as well as the controlling finger, will cause the' controlling pad to 'engage the 'top lof: the t can body, which will limit the downward movement of the outerend of the lever 34'. '-The further downward I 'movement'of the platefl9 will cause the" lever "34 to swing'about its fulcrum on the bracket the pusher will move underneath the can ends without engaging- 55- the lower, can-end in after anotheralong the support 7, the 0011- supporting ledge mes es trolling means will operate at each movement of the seaming head to allow a can head to be engaged and moved on to the 17. If, however, the oper-- ator fails to position the can body on the feeding-in mechanism, so that during one operation of the seaming head no can body is present to be closed, then the controlling pad 38 will move down with the plate 9, as there is no can body in the path of movement of the controlling pad, and the fin er will not be released from the stack hold er 'l" he finger is returned to its normal position supporting the ends in the stack holder by the weight 39.

It is sometimes desirable floating contents of a filled can prior to the placing of the can end on the same. In order to accomplish this depressing of the contents, I may form the controlling pad 38 with. a downwardly projecting center pen tion'lO, which substantially ts the inner side of the filled can, and will depress the floating contents into the can body. Said controlling pad is provided with. a ledge 41, which engages the edge of the can body and limits the downward movement of the pad end support for so as to operate the controlling finger.

It is obvious that minor changes in the details of construction maybe made, without departing from the spirit of my invention, as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
