Specification of Letters Patent.

, Patented May 5, 1914ia Application filed October 18, 1907. Serial No. 398,006.

To all whom it may concern:

Be it known that I,'Fnnn Vnoxsn, of Fan-port, in the county of Monroe and State of New York, have invented. certain new and useful Improvements in Can-Heading Machines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of the specification, and to the reference-numerals marked thereon.

The present invention which relates to can heading'machines has for an object to provide an improved construction in which filled cans in upright positions are fed to a can heading mechanism without injury to the cans or without the spilling of the con-' tents of the latter.

Another object is to provide for properly positioning the tops on the cans before the latter reach the can heading mechanism.

To. these and other ends the invention consists in certain improvements and combinations of-parts all as will be hereinafter more fully described. the novel features being pointed out in the claims at the end of the specification.

In the drawings: Figure 1 represents a side view of a machine constructed'in accordance with this invention. Figs. 2, 3, at and 5 represent sections respectively on lines cc and (Z-(Z of Fig. 1. Fig. 6 represents a view of the other side of the machine, parts being shown removed for the purpose of clearness. Figs. 7 and 8 represent two views of the feeding mechanism showing the latter in full lines in two positions, and in dotted lines in another position, and Fig. 9 represents a detail View of the ector.

In the present embodimentof my invention there is employed a frame or upright A upon which is suitably supported a can rotating member 1 and a rotary can support-'2.

T hese parts may be mounted in any suitable manner; but it is preferred to secure the former .on the lower end which carries a pulley 5 driven by a belt 6 passing over idlers 7 and around a pulley 8 on drive shaft 9. The can support is arranged below I the can rotating member and is'preferably movable toward the can rotating member in order that a oan may be clamped between of a verticalshaft 4 and in axial alinement with these parts, being for this purpose journaled on the upper end of a carrier 10 which is movable vertically in brackets 11 projecting from the front face of the frame A.

The mechanism for moi ing the rotary can support toward, the can rotating member comprises a horizontally arranged shaft 12 journaled in a bracket 13 and positioned on the front of the frame A below the carrier 10. Arranged on this shaft is a cam 14 on which rides a roller 15 on the carrier in order that the latter may rise and fall under the actionof the cam. I Theroller '15 may be yieldingly supported on the carrier so that the can may be held with yieldin pressure. In the present instance, this yie ding support is in the form of'a socket piece 16 slidable on the lower end of the carrier and connected by'links- 1 7 with a collar 18 loosely This collar is? loosely connected to a ring 19 by boltsf20.

surrounding said carrier.

which are surrounded by rubber cushions 21 arranged between the collar and the ring."

Arranged to act on ac'an clamped between the can support and the can rotating merinber is a seaming mechanism which in this instance comprises a pair of seaming rollers 22 carried by the slides 23 which are moved to seaming positions by cam'bars24; in turn operated by cams 25 on a'horizontal shaft 26.

arranged on therear of the frame A. Thiscam shaft is operated by a worm 27 driven from a pulley 28 on drive shaft 9 and-gear ing with a worm wheel 29 on the cam shaft 26. A suitable driving-connection between the cam shaft 26 and the cam shaft 125s provided so that the latter may be continuously operated, and preferably comprises a shaft 30 journaled in brackets 31 onthe side shafts by bevel pinions'32.

The cans are directed to the can support by a can guide 33 which is rigidly supported on the frameand has its outer end flared at of the frame A and geared to both of said when the latter is in a depressed position.

The cans areifed by handto' the flared-end and are caught loy a suitable feeding mechanism and delivered to the cansupport'l The feeding mechanism preferably comprises two cooperating feeding git-Wises; one an ranged on each side ofthe feeder andadifipted to reciprocate in the; direction of the length of the guide and also to move toward a {from -cans on thesupport.

of reciprocating and oscillatory bars arranged on opposite sides of the guide and Candevices 37 preferably project up-' guided in bearings 36 on the latter. ens s .wardlyrom'the bars and have their upper ends overhanging the guide and formed with curved recesses to fit the walls of theqcan's,

the ones first receiving the cans being elo'n- .gated so that in event the can is not in proper position to be engaged by the feeding devices the can will not be crushed.

The reciprocation of the feeding devices is effected through the medium of the constantly operated cam shaft 12 by means of a crank disk 39 connected by a link' lO with the lower end of an arm 41 extending from rock shaftj 420'11 frame A. This rock shaft {l2 has an arm 43 projecting upwardly therefrom and connected by a link l-fl with a head l5 which connects the bars 35 and permits the turning of .the latter,. but causes them to reciprocate therewith. The oscillation. of the feeding devices is effected by.

a pair of guides-4C6 and-47 connected at one end by a fixedswitch 48 and at the other end by a movable switch 49, the movable switch being normally held in one posit-ion by a springiil)- With these guides cooper- I ates the lower end of an arm 51 which devvice which transmits the motion of one to the other in a reverse direction thecans are gripped at the beginning of the forward forward movement. The device for effectmovement and relea'sedatthe end of said ing. the simultaneous oscillation of the bars is preferably in the form of a link connectin'gtwo] arms 53 projecting toward each other, from the bars or shafts, one being directed downwardly, the other being di re'cted upwardly, both being preferably turnable on the bars in order that the clampin action may be varied.

wing to the shape of the walls of the recesses in thecan engaging devices, the cans are compressed, into circular shape when clamped thus permitting the can tops to drop into the bodies. Should, however, the tops not be positioned properly they are shifted by suitable top positioning devices which are carried by the feeding devices and are preferably in the forin of fingers 55 projecting upwardly therefrom. v

While the cans are traveling on the guide v These devices, in "this embodiment, are in the form tr be/5,972

it, is desirable to have thempassunder'a pressure device which prevents their relation to eachlo'ther being disturbed, and at the same time tholds their tops inplace. v This device preferably comprises a plate 56 ex-' tending longitudinally of the g'uideand havfng. a s ring pressed bearing piece 57 arranged ongitudinally thereof, the outerends 158 and 5% cf'tnefplate and the bearing piece A being deflected upwardlyto permit the cans to pass freely beneath'thd pressure device.

After the seaming of the can head or top,

the cans may be removed from between the .cansup'portand the can rotating member by means of an automatically operating ejector, which preferably is in the form of a tri 'l lever 60pivoted intermediately of its on s at-61 in proximity .to said parts, as by'being mounted to turn on one of the bars 35, and being held againstinovement with the, bar by means of an arm 62 .whichenters a groove 63 in one of the bearings 36. v The .lower end of this trip lever carries a dog 64,

.trip lever may eject the can on the can support. When the support rises the dog 64 yields and permits the tappet to pass it.

without operating the ejector. v

Generally stated the operation is as follows: pans are fed by hand or otherwise to the guide 38 so that they may be engaged by the walls oft-he first pair of recesses inthe feeding devices. At this point, ,or in advance thereof, caps or heads are placed on the cans-and they are then-carried toward i i the seaming mechanism and under the pressure device me step by step or intermittent manner by the feeding mechanism, the lat- HOT.

ter shaping, the can; and positioning the cover so that thglatter will be forced into the body by the pressuredevice. As the can leaves the guidenit goes to the can support which then risesand clamps the can against the can rotating member. The can .is now released by the feeding mechanism and the seaming mechanism operates on the can. During the seaming operation, the cam 14 Inaintains the canelevated, and the feeding devices move to take anew can. At thecordance with this invention will seam cans at a very great speed without crushing them or spilling their contents, and further, cans which have become (hstorted are shaped so that the tops will properly fit them. The, construction is such that it is inexpensive to manufacture and at the same time simple 1n operation and durable in use.
