MACHINE FOR READING AND FLANGING CAN-BODIES.

Specification of Letters Patent.

Patented Mar. 21, 1916.

Application filed July 10, 1912. Serial No. 708,515.

T o all whom it may concern;

Be it known that 1, PETER Knuss, a (Ilt)izen of the United States, residing in the borough of Brooklyn, county of Kings, city and State of New York, have invented certaln new and useful Improvements in Machines for Beading and Flanging Can-Bodies, of which the following is a specification.

in the making of tin cans it is customary to feed fiat sheets oftin cut to the required size successively to apparatus which first bends up and down the opposite edges to form hooks; then advances the sheet to the point where it is folded around an expanding mandrel called the horn in such man- .ner that the. hooked edges are inter-hooked,

whereupon the horn expands and draws these hookstogether, and a ram called the bumper then descends and squeezes the inter-engaging hooks against the horn to form the side seam otthe can. This ends the work peculiar to the so-called bodyforming machine. The subsequentoperations depend upon the kind of can being made. For some purposes the can is hot tomed at one end and receives a slip cover at the otherend or top. For making such cans it is desirable to form a head just beneath the cover to stiflen the upper part of the can. For applyii'ig the bottom the opposite end of the can has to bo flanged, that is, its edges turned outwardly in order that it may later be double-seamed to the bot tom. For some cans the bead, instead of being at the opposite end from the flange,

is adjacent to the same end.

The present invention provides a machine for performing simultaneously, or nearly so, these. operations of beading and Hanging.

The machine provided by this invention may receive the can brdy after it is delivcred out of. the brdy-forming machine; or

the two may be built together so that the can body, after the sidc-seammg operation, is

pushed along on a prolongation of the. horn the bead. Vhile the can is held between the respective beading jaws whereby it is se-' curely clamped, a flanging die is pressed against its projecting end, partlyentering. the can, and expanding its end portion, whereby it is turned outwardly to form the flange. The beading jaws are then retracted to free the can body and the Hanging die recedes carrying the can with it, whereby the can is advanced beyond the plane of the beading jaws, whereupon it is dropped out of the machine. To insure the movement of the can with the receding die one or more ejectors are. provided which engage. the newly-formed flange and compel it to advance with the Hanging die.

The accmnpanyinp drznvings show a machine embodying this invention, of which- Figure 1 is a side elevation; Fig. 2 is. a vertical transverse section taken on the planes of lines in Fig. 1. Fig. 2 is a sectional fragment of Fig. 2. Fig.3 is a vertical section taken mainly on the plane of the line 3-3 in Fig. 2. Fig. 4 is a fragmentary transverse section on a larger scale, giving a face view ofthc beading jaws. Fig. 5 is a section in the planes of the'lines 5-5 in Fig. 4 shoeing the machine at the end of the heading and Smtllllflg operations. Fig. 6 is a face view of the heading jaws in their retracted or inactive position, the supporting parts being! omitted. Figsfi and 8 are a face view and plan of the wedge for expanding the inner. beading jaws. Figs. 9 and 10 are a face view and horizontal section of one. of thesejaws. Fig. 11 is a fragmentary clcratirn similar o; part of Fig. 1, but showing the machine in a diffcrent position. Fig. 12 is a fragmentary elevation looking in the direction "12' in Fig. 11.

In Fig. 1 let A represent the horn of the hoduforming machine, or an extension of such horn; or it may be any guide along which the successive can bodies are fed by any suitable means. present invention they might be fed by hand. 15 shows a fragment of theframe of the lioitwl'ormiug machine; or it might be any other suitable su 'iporting framc\\-'ork.

is thr man: tramc of the present machine l is a shaft which may be regarded as the driving shaft and may carry a belt pulley or any other suitable means for imparting 100. So far as concerns the. i

movement. As shown in 1 this shaft communi'ates motion through miter gears a a to a shaft E which in turn communicates movement through miter gears 2') to a shaft F. The shafts D and F revolve synchronously. The shaft 1) carries an cecentric G (Fig. 3) which is encircled by eccentric'strap connecting by a link 0 to one arm of a lever d,.tl1e opposite or longer arm of which connects by a link 6 to any suitable part of a slide H whereby this slide is reciprocated regularly by the operation of the eccentric. The slide H slides in ways ,5. formed on the top of the frame C, as best shown. in Fig. 2. The link 6 connects with an adjustable piece f clamped to the slide by a block 9 which is adjustable by a'screw whereby the slide may be set forward or backward, as may be required (see Fig. ,3).

The shaft F carries a cam J, the groove of which acts upon a roller carried on the lower arm of a lever j, the upper arm of which connects by a link I: to a yoke l engaging a rod K, which has sliding hearings in the opposite endsof the slide H. For adjusting this rod longitudinally set-nuts m m are provided. The front end of the rod is supported by a plate 11. fastened on the front of the slide H.

The fianging die L is carried on the front end of the slide H against the plate a and the rod K moves freely through a central hole in this die.

The beading mechanism comprises outer beading jaws M M shown as four in number, which encircle the can, and inner beading jaws P P, (Fig. 6) also shown as four in number, which are adapted to'fit within the can. The outer jaws have in their inner faces a circumferential groove; and the inner jaws have on their outer faces a similar but smaller circumferential rib in the same plane with said groove, so that when the respective jaws are forced together the rib-and groove cooperate to form the bead. The inner jaws are supported by the end of the mandrel or horn A, (Fig. 5) being overlaid by 'a plate 7) fastened by screws to the horn or mandrel. Each jaw is confined to a radial movement by being formed with a-rib 1", Figs. 9 and 10, which slides in a radial groove in the end of the mandrel A. The sections are moved by an expander Q, igs. 7 and 8, which has essentially four wedge-shaped faces engaging the inner faces of the four jaws. These faces are dovetails s engaging dovetailed grooves s in the jaws, as shown in Figs. 8 to 10. The expander Q, is pressed out by a spring t to contract the jaws and is pushed in by the rod K to expancl the jaws. The outer jaws M M, which are preferably alternated in arrangement with the inner awsg" are also moved radially and simultaneously. They are shown in their inner positions in Fig. 4 and in their outer pO-Sllltms in i- 5. The jaws are mounted on radial slides M mounted in a special .iratae R. The jaws are drawn outw rdly by springs u They are forced inwardly by a cam ring S shown best in 6, which is given an oscillatory movement "wl'ioreby the cam surfaces or notches '2: r are brought into or 'out of engz-igenient with rollers 1: o carriedon their respective slides M. The ring S is connected to an arm 5 which connects by a rod T to a crank U conveniently carried on miter gear (12, Fig. l. ()n the downstroke of the crank a downward pull is communicated through the rod T which positively pulls down on the arm i." and oscillates the ring S to the position where the cam notches 'uvcoincide with the rollers '12, thereby opening the jaws M M as shown in Fig. 6. The opposite i'novement oscillates the ring to cause the cams v to force the jaws inwardly; and as in this 'a'iovement the grasp and embrace the can body, it is desirable, to allow for slight variations in the diameter of the can or the thickness of the sheet metal, that this active movement of the ring 5 should be performed yieldingly in order that the jaws may not be pressed in too far. For this purpose the connecting 10d T is made telescopic or collapsible, in. manner best shown in. Fig. The rod is dividedintc two parts between which is a stiff spring S The upper part of the rod enters into a sleeve T making a sliding fit therewith, while the lower partof the sleeve T is screw-threaded and engages the threaded lower end of the rod. The sleeve has a slot into which projects a pin 10 carried by the upper section of the rod, the slot being sufliciently long to allow for the desired yielding movement. In the down-stroke the end of the slot remains in contact with the pin 10 as shown in Fig. 2 and thus the movement imparted is positive; while on the up- SUOliQ the thrust is communicated through the a ring J" and is yielding. For adjustthe length of the connecting rod T the sleeve T is screwed up or down and locked by a nut to.

The operation is as follows :-A.ssuming the machine to be built as a. continuation of an ordinary can-body-forming machine, the can body from the latter is pushed along the horn Aby means of a reciprocating feeding pusher V, Fig. 5, or in any other manner. The can body is shown at X in Fig. 5. The cam ring S in its oscillations then forces inward the jaws M M until they tightly grip the can'body and hold it, forming thereby an annular anvil. Meanwhile the slide H and rod K have been approaching the can body from the right in Figs. 1 aud o, and before the fianging die L reaches the can body the advancing end of the rod K strikes the expander Q and pushes it back l to animov use tin; flanging die to opei'aie.
