MACHINE FOR SEAMING HEADS ON CANS.

TAIL-52,188.

To all whom it may concern: Be it known that 1, PETER KRUSE, a c tlzen of the United States, residing in the borough of Brooklyn, county of Kings, city and State of New York, have invented certain new and useful Improvements in Machines for Seaming Heads on Cans, of which the following is a specification.

This invention relates to machines for seaming heads or ends on cans or, canbodies, and aims to provide improvements therein.

The machine of the present lnventlon 1s of the type known as two-spindle machines, and contains improvements whereby the seaming operation may be under the ready and constant observation of the operator, and whereby any irregularlties 1n the operation of the seaming mechanlsm may be readily observed and quickly and readily rectified.

The invention further provides improvements in the general machine structure.

The invention further provides improvements in the seaming mechanism whereby changes may be made for adapting the mechanism for operating on different sized cans with greater readiness than heretofore.

An embodiment of the invention is illustrated in the accompanying drawings, wherein Figure 1 is a front elevation; Fig. 1 is a fragmentary side elevation of the top part of the machine; Fig. 2 is a horizontal section on line 2-2 of Fig. 1; Fig. 3 is a horizontal section on line 3-3 of Fig. 1; Fig. 4 is a top-plan View with parts broken away to show one of the seaming mechanisms; Fig. 5 is a diagrammatic view illustrating the action of the seaming rolls upon a canhead; Fig. 6 is a view in elevation (with parts in section and parts omitted) of the seaming mechanism; Figs. 7, 8 and 9 are views of a similar seaming mechanism to that disclosed in Figs. 4, 5 7 being a horizontal sectional view through the upper part of the seaming mechanism, Fig. 8 a diagrammatic view similar to Fig. 5, and Fig. 9 a vertical section of the mechanism with parts in elevation.

7 mechanism, and B a second seaming mech anism.

a and b are, respectively, the seaming heads of the mechanisms A and B, carrying, respectively the seaming rolls a and I).

he seaming heads a and b, respectively, are driven" by the spindles C and D, which i are rotated from a vertical drive-shaft E through the intermediary of a gear 6 and pinions c and d respectively. The driveshaft E may be driven in suitable manner by means of a pulley F mounted upon a horizontal shaft f and connected to the shaft E through suitable bevel gears 7.

l G designates a turntable which may be provided for receiving the cans. The turntable G is preferably driven from shaft E by sets of gears g g on the shafts H and I are feed tables for the cans or bodies, and J and K are feed disks. The feed disks J and K are intermittently actuated preferably through a Geneva wheel L driven shaft E, andgear wheels Z Z connected to the shafts j and is of the disks J and K. The feed disk J receives the cans from the turntable G and carries them past a suitable selective can-head feeding mechanism M to a position beneath the first seaming mechanism A, and the feed disk K carries the cans with the heads partially seamed there on to a position beneath the second seaming mechanism B, where the seaming is completed, and from thence on to a suitable carrying-ofl device N. The feed disks J and K rotate in opposite directions, and the disk K rotates toward the front of the machine, in such manner that the cans with the partially seamed can-heads thereon, coming from the seaming mechanism A, are moved to the front of the machine, clear of the seaming mechanism and in clear view of the operator, where they may be readily observed or examined by the operator. The feed tables H and I are provided with guides in and z for the cans, and the guide 2' is preferably provided with removable or pivotal portions i i which may be readily swung open so as to provide for ready removal of the can for inspection or rejection. The feed disks J and K are adapted'to the main match beneath the first seaming mechanism in such manner that when the can is in position in the firstseamlng mechanlsm t is rounded or straightenedup into its proper they are raised against the chucks a and b respectively of the seaming mechanisms by the plungers O and P respectively. The plungers O and P are actuated by a slide Q, sliding in usual ways on the main frame, which slide is raised and lowered by a cam q mounted upon the drive-shaft E which acts upon a roller g upon the slide Q. The slide preferably acts upon the plungers O and P through resilient means such as springs 0 and p.

The seaming mechanisms A and B (Figs. 49) comprise the seaming heads a and b, which are fixed upon the hollow rotary spindles C and D. The seaming rolls a a and b b are carried by arms a a? and b b respectively, fixed upon pins a a 12 5*, which are pivotally mounted in the seaming heads a and b respectively. The sealing rolls a. a, and b b are moved inwardly into contact with the can-heads or ends by means of hoods or shells R and S carrying cams adapted to engage shoes a a and b b mounted on arms a a and b b fixed upon the pins a a and b b respectively. The hoods or shells R and S are mounted upon rotary hollow shafts r and s respectively which are journaled in a. slide T which is suitably guided upon the main frame of the machine, and is moved up and down by a cam t mounted upon the drive-shaft E, the cam acting upon a roller 25 carried upon the slide T. The shafts 1' and s, are keyed to the spindles C and D and partake of the rotary movement thereof. Up and down movements of the hoods Rand S under the influence of'the cam 25 brings the cams carried by the hoods into and out of contact with the shoes a 12 and consequently effects the inward movement of the rollers against the can-heads, and the release of the rollers, the rollers moving outwardly by centrifugal force.

'The hoods or shells R and S 'are preferably formed as separate parts, and connected to flanges 1' s which may be provided upon the shafts r and 8. The hoods R and S are preferably provided with a plurality of sets of cams 1* r 1' 1' 7' r 8 s, s s, s 8 The cams of the respective sets upon each hood are at different radial distances and are hence adapted to move the rollers inwardly to progressively greater extent, in such manner that the seaming roll. may be made to operate upon cans of different diameters by selecting :an appropriate set of cams. The several sets of cams on each of the hoods R and S may be brought into proper position for engaging the shoes connected with the several seaming rolls, by removing the bolts 7' s and shifting the hoods circumferentially to a proper position. For positioning the hoods upon the shafts, the flanges r? ands may be provided with a plurality of holes 1' 1' r, and the hood with a hole 1" through which a pin 7* is adapted to be inserted into one of the holes 1", 'r' or 1', as shown in Fig. 4. For convenience and expedition in placing the hoods on and taking them off the shafts r and s, the hoods are each constructed in two or more parts adapted to be separated and be brought together around the shafts. The different parts may be connected by cleats r, as shown in Fig. 4.

The chucks a and b are carried by hollow sleeves a (4 extending through the hollow spindles C D and fixed in brackets a, b at the top of the machine. Knock-outs U and V extending through the hollow slee 'es a b may be provided. The knock-outs may be operated by a cam u which actuates a roller '0 on the end of a rod 12 connected to a rock-arm 0 connected to the knock-outs U and V by means of links o o;

The feed mechanism M will be briefly described. In general construction it resembles the feed-mechanism disclosed in my United States Patent No. 1,058,372, dated April 8, 1913.

m (Fig. 2) is a reciprocatory slide carrying a pair of knives m m adapted to separate a single can-head from the bottom of a stack of can-heads in the hopper m The slide on is preferably operated by a lever m connected by means of a pitman rod m to a crank pin on a gear 112? meshing with a gear m fixed upon the drive-shaft E.

m is a pusher adapted to push the separated can-heads from beneath the hopper. The feed of the can-heads is controlled by a reciprocatory rod we having a recess m therein and connected to a bell-crank m. The pusher 'm. normally rests wlthin the recess m in the rod m. hen a can passes the bell-crank m, the bell-crank operates the rod m, lifting the pusher out of the recess m and causing it, when carried forward by the slide m, to contact with a can-head and push the same from beneath the hopper. When a can-body fails to operate upon the bell-crank m the pusher 777. will not be raised and will consequently fail to push out a can head when carried forward by the slide m. When 'a can-head is pushed from beneath the hopper, it is carried forward over its can by the feed disk J to the first seaming position, being supported by ledges h on the guide H and ledges 7' on the feed disk'J. The feed disk J is also provided with ledges k for supporting the can-heads, in conjunction with the ledges j on the lit All feed disk J1, over the cans in the first seaming position.

The turn-table G, the feed-table H, and the feed-table I are preferably mounted upon a common or unitary frame W (Fig. 3) which slides in guides 10 attached to the main frame of the machine; The frame W is adapted to be adjusted as a whole by the hand-wheel w. justment of the machine to cans of different heights is facilitated.

The operation of the machine is as follows :Cans or bodies at m are received upon the turn-table G and carried to the feed-disk J. The cans are thence carried to the first seaming mechanism A past-the can-head feed mechanism M which operates to feed a head for each can fed to the 'machine. When the can reaches the first seamingposition 00 it is rounded by the feed-disks J and K and pressed upwardly by the plunger 0 into engagement with the superposed can-head and against the chuck a The shell R is thereupon lowered by the cam t, bringing the camscarried by the slide B into contact with the shoes connected with the seaming rolls a a, forcing the seaming rolls a a into contact with the can-head to clench and partially seam the same upon,

the can. The can with the partiallv seamed head thereon then descends to the level of the feed-table with the plunger, assisted by the knock-out U, and is thereupon fed by the disk K to a position at the front of the machine where the can can be readily and quickly observed, and removed if desired. The can thereupon passes the second seaming mechanism B. In this position the can is raised against the chuck'bl by the plunger]? and the seaming of the head upon the can is completed by the seaming mechanism B in a manner similar to the operation of the seaming mechanism A. The can thereupon descends with the plunger P, assisted by the knock-outV, to the level of the feed-table, and is fed from the machine, with the assistance of an ejector X, onto the carrying-off device N.

The invention may receive other embodiments than that illustrated and specifically described.
