To all whom it may concern:

* Be it'known that I, P TER Knusn, a citizen. 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 'tor beaming Can-Tops, of which the following is a specification;

The machine provided by this invention is designed for cans, and is particularly adapted for seaming the tops or covers on cans already filled.

lhe can is held stationary, and is seamed by.

seamers or seaming rolls which revolve around it and which while so revolving gradually close 1n upon it. The cans to be seamed are in the preferred construction fed onto conveyor which carries them to a feed disk, whereby the cans are brought successively into position beneath the seamers; the can thus placed is then lifted bya plunger to bring its top into the plane of the seaming rolls and is held there during the seaming operation, after which it is lowered,

and by the next movement oi? the feed disk the finished can is carried out of the machine.- The machine while preferably de signed and adapted for the performance of these functions, is nevertheless adaptable to other uses as will be made apparent.

The complete machine in its preferred 'form is shown in front elevation in Figure 1 and in side elevation in Fig. 2, the latter viewbeing partly a vertical section. Fig.

3 is a plan of the feeding means, the view being partly a horizontal section; F ig. at is a horizontal section showing the means for turning the can feed disk; Fig. 5 is a vertical section of the seaming rolls and their planes of the lines Fig. 6 is a plan of the scainiu rolls Fi 1.0 is a olan of the b a m l cover-feed all lower parts not pertaining thereto being omitted to avoid obscurity; Figs. 11, 12 and 13 are internal sections of the cover-feed in successive positions.

Referring to the drawings, A designates seaming the heads of round guide pulleys (Z d to a pulley any suitable frame or standard for supporting the operative parts, being shownas an upright frame providing bearings for the rotati'vc shafts and slideways for the sliding parts, as will appear. In the preferred construction shown, power is applied to a horizontal shaft B through tast and loose pulleys a a or otherwise, and from a pulley b on this .shaft a belt D is carried over shaft G, whereby the latter shaft is driven either at the same speed as the driving shaft or at a different speed as desired. The shaft C is hollow, and through it passes a stationary rod E fixedly clamped in a bracket 6 on the frame A at its upper end, while the lower end of the rod carries a pad or disk F against which the top of the can is to be pressed and held during the seaming The lower end of the tubular shaft C carries a head or disk Gr which forms a bearing for the spindles of the seamer rolls.

0 on a vertical The construction of the seamers is best shown in Figs. 5', 6, 7 and 8. The scanner rolls H are carried each on a stud h in an arm f which is mounted on the lower end of a spindle q, the upper end of which carries a control ing arm i acted on by a scameractuating shell J. The arm c1 carries a stud a" on which is hung a shoe or runner I, all as clearly shown in the perspective View Fig. 8. The shoes I I are received within the'internally-coned shell J. Preferably the stud g is squared at its lower end and between this squared end and the arm f is a bushing e fitted on this squared end and fastened by a pin 0 or otherwise; the bushing has :1 lug a received between two set-screwsg" g on the arm f, so that by adjusting these screws the arm 1 may be swung; around the axis of the spindle g to carry the roll H toward or from the center of the can, and thereby to regulate the thickness of the seam, or adjust the seaming-roll to the exact diameter of the can. For double seaming it is preferable to use two pairs of seaming rolls H H, one pair being arranged diametrically oppositeto control these rolls are mounted lilee thd shoes l I, except that they are set somewhat lower. The seaming rollsla-re caused to approach the can (g hig. 7) while revolving around it, by means-pf a downwardmovement of the "shell ,J', so that its coned inner surface 9' forgs the shoes I I inward. The shoes I I ltyfbeing set'higher than the shoes I I are first acted upon and forced inward" as the shellmoves downwarthso that the primary r seaming rolls HII move inward first to perform the first part of the seaming operation;

then as the shell J moves farther down the secondary or finishing rolls H H come into action; at the instant when the primary rolls H complete their work their shoes I I pass beyond the cone surface j and begin (see I, -1'5 Fig. to ascend a parallel or cylindrical surfacejj (or this might be anexpanding surface if itis desired to permit the primary rolls to move outward and disengage the seam); the shoes I may engage only the coned surface y', or may in turn run against the surface j; when the seaming operations have been. completed the shell J moves upward, thereby permitting the shoes I I and rolls H H to move outwardly by the centrifcan. Thus the shell J whichby its vertical u gal tendency, thereby freeing the finished 'movement controls the inward and outward movements of the seamers, necessarily executes one downward and thenone upward cam-groove of which engages a roller 1 (Fig. I on a vertically moving slide L movable 6 movement to each; can that is seamed, followed b adwellof sufiicient duration to permit t e seamed can to be removed and a new can to be brought into place. For-imparting this relatively slow movement the driv ng shaft B drives through reducing gearing (for example a worm is and worm- 'wheel k) a shaft K carrying a cam K the in ways in the main frame A, which slide at its upper part is formed with a bracket L to whlch the coned shell J is connected. The

shaft K .turns once to each seaming operat1on.. The shell J mi h-t behon-rotative,

and the shoes I'I slide around within it; or

to diminish'friction the shoes mi ht bereplaced by rollers; but preferably te shell J 1's 'made to rotate with the shoes, being carried with them frictionally, and to diminish friction between the shell and the bracket L ballbearings are interposed. A suitable construction is that shown, where the shell is '60 shaft is fixed the crank disk P of at Geneva "s'top n ovement, its crank p driving a star fastened to a cap J" having a hub turning freely in the bracket L, and with two interposed series of balls 1: and c ali'oveand below the 'bracket to transmit the vertical thrusts.

The shaft K drives'through miter gears m m a vertical shaft M which drives the feed mechanism. On the upper end of this .wheel Q onv a shaft Q, which carries .a

7 notched feeding disk It, all as best shown in Figs. 2and4. Beneath the disk R isa .ver-

' to the ca tically'movable plunger S in line with the shaft 0. The can is pushedover the'top of a table T onto 'the plunger S, which is then raisedto bringthecan into the seaming position. This movement is derived from the shaft M which carries a cam S (conven: iently formed in one part with the crank disk P), the, cam surface of which acts on a roller t on a lever t the long arm of which engages an upright-spindle s (or other sliding frame) carrying the plunger St The 'plunger is thus held elevated during the entire seaming operation, at the end of-which its roller it runs off the cam incline s and lowers the plunger, which remains down while the crank p is turning the star wheel to carry off the seamed can and feed into place a new can, whereupon the incline s lifts the roller t and again elevates the plunger for a new seaming operation.

The cans'to be seamed are'fed by the operator onto a feeding rack or chute U, along which they are caused to travel by an endless chain V turning on sprocket wheels 1) 'v. This chain may -b'e'suitably driven, preferably from the shaft K, through chains 11; w carried over suitable sprockets. The chain Vcarries the cans (q 9, Fig. 3) onto the table T and into the successive notches in the feed disk R. This disk turns. intermittently and carries the successive cans onto the plunger For feeding the cans out of the machine, an inclined chute Wis provided, so located that the feed disk R pushes the cans off the table T and into this chute, down which they may slide by gravity. One side of this chute is extende as a rim around the table T, as shown'in Fig. 3, to prevent the accidental escape of the cans while being fed by by the plunger S, i-t finds its cover in concentric position above it and enters the cover and lifts it against the disk F into position for tshe seaming-rolls to unite the cover ported stationary upright tube or skeleton frame in which the covers are-placed and loosely held. The disk X has a series of holes fitted with bushing rings 3/ y Which stop successively beneath the stack, each ring The stack Y is a suitably-sup having a recess into which the lowermost I cover 9 may partly enter (see Fig. 11) so that at the next movement of the disk this to enter the next turning the disk R to varying positions the seaming rolls H H; The opening through pressed push-out pad F fastened h'gher or lower on the frame-A;

ries an auxiliary disk R fastened to it by .i teed disk X to feed covers of different diaway by the ring so that next cover may descend onto the disk,

ring in its turn. The underside of each ring 3/ is coned aty so that when the movement of the disk has brought the cover directly over the can '(see Fig. 12), this coned surface will serve as a guide for the rising. can, to cause the can to enter the ring, and receive and lift the cover (see l i'g: 13), so that the cover and can will be broughtin correct, concentric positioh up againstthe disk F and within the revolving cover is carried the the ring 1 is too small to admit the cover, but is large enough to admit the flanged can body, and to permit the seamed can to pass down through it. To assist in freeing the seamed can from the disk F a spring is provided, the stem of which seats against a spring housed in the stationary shaft E, (see Fig. 5.

The machine is designed to be readily adapted to varying sizes of' cans, whether the variations be in height or diameter. For adjusting the machine for dittercnt heights of cans. the feed mechanism is carried by a special trains or bracket A, which may be and the shaft M is made in we parts. the one sliding within the other and'splincd togetlmr. The coverdeed disk X. may beset higher or lower relatively tothe shaft {,2} to restore it to the proper level after any adjustn'ient ot' the height ofxthebracket A. The feed chute U has side" guide bars u u fastened adjustably at u, so thatjthey may be moved toward or from the center to accon'imodate cansott' varying diameters. For adjusting it to cans of varying heights,the' chute U may be raised or lowered together with the table T and other parts of the feed mechanism described, the chains to wl adapting themselves to this movement since the axes of their sprockets are connected through links as w. The outer end of the feed chute U may be supported by a telesropirally-adjustable support U. The can t'eed disk R is made adaptable to cans of. varying diameters by making its notches adjustable; and for this purposethe disk cara set-screw r and having projections r entering the notches 1n the disk B, so that by e'iliective width of the can-receivii1g notches may be varied as desired. The sehscrew r may engage an arc-shaped slot in one of the disks, or preferably holes 1' registering'in varying sizes of cans to be handled. To prevent the operators clothing being caught by the disk R R it is desirable to extend a guard rail or curved bar 7" around it, as

shown in Fig. 3. F or adapting the cover replaced by in size tolhe covers to be used. For adjusting the seamers t0 cans fof varying diameters (Where the adjustment exceeds the way.

ameters its bushing rings y y are made detachable so that they may be removed and rings having openings adapted capacity afforded by the screws g), it is only necessary'to provide a series of bushings e, having their lugs e projecting at different angles relatively to the squared end of the spindle g, so that by substituting a dilferent bushing the arm f is projected to a different angle, or H is brought to a different distance from the axis of rotation. For an extreme adjustment the shell J may b'removed and replaced by a larger or smaller shell; and if necessary a larger or smaller head G may be provided.

The machine described is very simple in construction, has few Working parts. operates automatically and with great rapidity in the seaming of filled cans, which are held stationary during the seaming operation; and is easily adjusted to receive cans of varying sizes.

The machine may be used for seaming the bottoms of empty can bodies by presenting" them to'it in inverted position.

The primary and secondary seamin-g rolls are best arranged in pairs and diametrically opposite, in order to equalize the pressure during the seaming operation but this is -not essent al since except tor the disadvantage of an unbalanced or one-sided pressure3oi1e roll of each pair could be omitted.v

To guard against-the possibility that any of the covers 9 might. drop through the openings inthe bushings 3/, due to the clearance being necessarily very small, and be.-

cause of some irregularity in the punching of the covers, any suitable stop may be provided to constitute a temporary false 'bottom in the bushing. A convenient'construction is that shown in Figs. 10 and 11, where a leaf spring Z (shown in dotted lines in Fig. 10) is fastened to a bracket Z, and is arranged to press upwardly against. the under side of the disk X, so that in each stopping position thereof it will enter partly within the opening in the bushing directly beneath the reservoir Y. as shown in Fig. 11.

As the disk X turns, it first starts the lower- 'most cover out from under the reservoir,

after which the edge of the bushing strikes the spring,Z and presses it down out of the If any cover should be small enough and its seaming roll H to fall through the opening, it will strike,

the spring Z and be upheld.
