To all whom it may. concern.-

Be it known that I, 'BROR J Lnnosann, a

citizen of the United States, residing at But-- ialo, in the county of Erie and State of New York, have invented a new and useful 1m- PIOVGIHGII'G in Machines for Heading Cans and Boxes, of which the following is a speci fication.

This invention relates to machines for securing the ends-or heads upon cans or boxes of rectangular or other non-circular form, and more particularly to double-seaming machines for securing the cover-heads on filled cans or boxes of the kind in which-sardines are packed. Such a machine is herein described, and shown in the drawings; but certain features of the improvements are not limited in application to a doubleseaming machine nor to a machine for securing the covers on filled cans, as will be apparent from the followin description.

The rincipal o jects of the invention are to pro nee an efiicient desirable automatic machine of maximum capacity for seaming the ends on cans or boxes, especially non-circular cans or boxes; to provide a straight way intermittent feed. for the cans which will permit of rapid operation withontdislodging the loose heads from the cans or scattering contents of the cans; to so construct the machine that it will producepericct work and can be operated at high speed with but very little noise and wear on the parts, and to improve the machine in other respects herein- 5;; after pointed out, and set forth in theclaiins. In the accompanying drawings, consisting of five sheets, Figure 1 is a side elevation, partly in section, of a can-heading machine embodying the invention. Fig. 2 is a plan 0 view thereof. Fig. 3 is a'horizontal section thereof, partly in plan, in line 3 3, Fig. 1. Fig. 4 is afront elevation, artly in section thereof.

Like letters of reference refer to like parts in the several figures.

The machine hereinafter described, and

shown in the drawings, secures the can end or head to the can by a double seam of the character shown in Figs. 13 to 16, whi,ch fignres also illustrate the successive Ste 5 in the formation of the seam. The can has an outwardly-projecting top flange a2, and the end or head has a depressed center, which sits down in the can, and. a depending marginal flange fly, which surrounds the to flange of the can. The flan e 'y of the bee is first turned in under the i ange tool the can, the interlocked flanges are then bent down at an angle, and finally the seam is pressed in against the wall of the can and completed, as shown in Figs. 14, i5, and 16, respectively.

The machine, briefly stated, is organized and operates as follows: The cans, with the ends or heads. resting loosely thereon, are placed in anintermittently-moving straightway conveyor, which at each movementadevances a can, withits head, to'a osition between the heads of a chuck. lie the conveyer is at rest the can and head are elevated and held by the chuck stationarily above the conveyor While the seeming is performed. suitahlvshaped rolls, which are journaled on contour and seaming carriers mounted on'a continuonslyrotating head, during the r'evo lutions of which about the chuck the contourcarriers cause the rolls to travel in a path substantially parallel with the seam, while the seaming-carriers presentthe rolls to and retract them from seaming position in succession, so as to perform the six lBSSlVe steps of the operation. searningwoll has been rri i-r the last the chuck The seam is produced by 'a series of "secured to the cylinder.

deposits the headed can in the conveyer, and he latter moves another step to carry the leaded can away from the chuck and present another can and head to the chuck. The machine is continuous in operation, and it is only necessary for the operator to place the cans, with their loose heads, in the conveyor, after which the machine automatically heads and discharges the cans.

A represents the main frame, which may be of any suitable construction, that shown consisting of an 'uprighthollow column or standard provided with forwardly-projecting upper, lower, and intermediate bearing-arms a a a for the can chuck and seaming mechanisrn.

B represents the revolving head which carries the seaming mechanism. It is preferably a hollow open-bottomed cylinder provided with an inwardly-extending annular bottom llange or ring I), bolted or separately 'lhehead is secured. to or formed on the lower end. of vert'ical hollow shaft 1;, Figs. 4 and 7, iournaled in the upper bearing-arm c of the frame and in a stationary sleeve clamped in the intermediate bearing-arm a. of the standard. The seaming-head is continuously rotated by suitable drive mechanism. As shown, the seaming-head shaft has fixed to it, between the upper and. intermediate hearing-arms, a belt-pulley a, connected by a belt c with a belt-pulley 13" on a drive-slutft (l, Figs. 1 and 2, which is journuled in suitable hearings in the lower part of the standard and a bearingpost c", rising from. the baseof the standard, and is provided with tight and loose drivepulleys a. 'lhc belt 0 runs over ordinary guide-pulleys r", journalcd n the upper portion of the standard and provided with means for adjusting them to pr perly ten sion the belt. Any other suitable means for driving the seaming-head can be employed, The seaming-head run be adjusted vert. :ully by nuts screwed on a threaded portion of the-hollow shaft 1) above the belt-pulley c. The latter is held from downward movement by the stationary bearing-sleeve If and an interposed gear-wheel, hereinafter referred to, so that the hollow shaft and seaminrehead can be raised and lowered byturning the nuts 0 t 'lhe chuck for holding the can stationary winle the seaming-bend revolves around the same to produce the seam comprises upper and lower heads orplates l) l). 'lhe upper r-.huel head is of a size and shape to properly lit in the depression of the end or cover of l he can 'or'box and form a mandrel or internal support for the seam while it is being pressed and will of course dill'er in machines for operatine upon cans of different l'o'rm'and for making, dill'erent types of seams. 'lhe head l)shown is of reel angularsh'ape and tits down in th correspondingly shaped depression of the can end, as shown in Figs. 1'3 to Iii. it is located centrally in the revolving scans hag-head and is lixed to the lower end of a stationary vertical rod ,or shaft d, which passes loosely through the hollow shaft of the seaming-howl and is secured at its upper end to a bracket d at the topoi the standard, as by nuts /j, screwed on the threaded end of the rod above and belowthe bracket d. By means of these nuts (1" the clnwk-head (an be adjusted vertically to the proper position relative to th. seaming mechanism. 'lhe lower chuck-head l) is shaped to tit and hold the can to beoperatcd upon and is movable toward and from the upper head to grasp and release the can. 'lhe lower clnu-k-head shown r ctangular and is provided on its four sides with upright lingers d, Fig. 17, lnetween which the can is confined. A can with the end or cover resting loosely thereon is moved to a position over the lower chuckhead whiicjin its lower position by the intermittent-feed conveyer to be hereinafter described, and the lower chuck-head is then raised, carrying the can up and clamping it and its end against the upper chuck-head, where it is held until seamed, when the lower head again lowers and deposits the headed can again in the feedconveyer. For this purpose the lower chuck-head is lixed to the upper end of a vertical rod d", which is inovabie vertically in a guide-hole in the lower bearing-amt a of the frame and is operated, preferably, by the following mechanism: A vertical countrr-shaft. E, Figs. 2, 3, and 4, is journaled in suitable bearings atone side of the standard and driven from the hollow shaft of the seaming-head by a suitable train ol gear-wheels, one of which, c, is

secured to the upper end of the shaft l) and another, c, ol. which is the gear "l'iefore referred to as secured to the hollow shaft of the seaming-lived below its drive-pulley. A

worm a", secured to the lower portion oi" the vertical counter-slnift lLnneshcs with and drives a. worm gearwheel a", secured to a horimntal cam-shaft 1 which passes through and is jonrnaled in hearings in the standard A. (See Fig.3. A cainf, secured to one end of this shaft, engages a stud or rollcl'f,

pl'fljittltlilg from one end oi' a rod f, Fig. 1,

which is siotted at and slides on the cam shaftand is connected at its other end to an armf", secured to a rock-shaltf", journaled in the standard. The roek-shaft has 'another arinf, the forked end of which is pivotally connected to an adjustable collar f on the lower end of the movable chuck-rod d; A s'p'ringf" is preferably interposed. between an adjustable collar or nut f" on the sliderodf and the roelealpr/"Q so that the chuckrod is moved up with a yielding pressure and is allowed to stop to avoid injury to the Inachine in the-evei'it that the upward moveinrnt of the chuck-rod is prevented from any iio cause. The adjustable collar f on the chuck-rod (see Fig. 7) is preferably ,a split collar clamped on the chuck-rod and connected by an adjusting-screw f" and nuts f witha second split collar f, clamped on the chuck-rod. This construction enables a more accurate adjustment of the movable chuck-head, as the adjustable collar f" can beloosened and adjusted minutely on the chuck rod by the adjusting-screw and nuts f f and then secured by tightening up the split collar.

G represents a horizontal feed-table along which the cans, with the heads resting loosely thereon, are fed by an intermittent conveyer to a position between the chuck-heads and againmovcd away from the chucks after the seaming operation. The table is preferably supported; by two brackets g g, .which secured to opposite sides of the lower bearingarmel the standard and extend laterally in opposite directions therefrom beneath the Thereccrving end of the table, which extendsijarthcr out from the standard A, is also preferably steadied by a vertical post 9 provided with a suitable base and secured at its upper end to the outer end of the lateral bracket g.

The intermittent conveyor (see'l igs. 3, 4;, and 5) consists of two endless chains or belts H' H, arran ed on top of the table parallel with each ot er in the same horiontai plane. Each belt or chain passes around two horizontal sprocket-wheels h It, secured to the upright shafts h h, respectively. The shafts h of the two conveyer-chains are journaled in suitable hearings in the bracket 9 and are rotated intermittently in opposite directions, so that the two adjacent or contiguous runs of the conveyor chains or belts move together from the receiving end of the table past the chuck by drive mechanism to be presently described. The shaits h of the other sprocket wheels, which are simply idle wheels, pass through slots h in the feed-table and are adjustably secured in' any suitable manner to an extension b of the lateral supporting-bracket g for the table. The conveyer-chains can be properly tcnsioned by adjusting the idle sprocket-wheels hi. Each conveyer chain or belt is provided with a series of horizontally-projecting lugs or pieces i, arran ed in pairs in such manner that each pair of ugs on one chain is directly opposite to a pair of lugs on the adjacent run of the other chain, the opposite pairs of lugs on the belts thus forming as they inovc together along the feed-table a series of pockets or holders to receive the cans or boxes] The lugs 'LLLIO of ashape to form pockets similar in.

shape and size to the cans or boxes to be operated upon, those shown forming substan tially rectangular pockets and having rabbets or grooves 'i, Figs. 3 and 7, in their upper portions to receive and hold the flanged can-head. In. order to enable the cans, with their covers, to be readily placed in and discharged iron; the holders oi the conveyors and at the same time insure their proper register with the chuck, the adjacent runs of thetwo conveyor-chains are separated farthest apart at the ends of the table and are caused to converge slight ly from the table ends toward the chuck by converging guides i, ris ing from the table. The holders are thus ex panded suliiciently at the receiving end of the table to readily receive and loosely c'online the cans and heads; but as the holders move along toward the chuck they gradually contract until when between the heads of the chuck they register accurately with the latter, so that the lower movable head of the chuck can FIIIUVB up through one of the holders at each rest period of the conveyor and hit its can to the seaming position. As the holders move from. the chuck toward the discharge end of the table they again spread or expand somewhat, and when the holderlugs pass around the sprocket-wheels h for the com-*eyer-chains they completely free the hooded cans and allow them to drop into an inclined discharge-elude i" at the discharge end of the table.

The feed -conveyei is driven inlern1ittently by any suitable means, the following mechanism being" desirable: A wheel K, Figs. 5 and 6, is secured to one end. of the cam-shalt F and has a peripheral groove is, which is crossed at one point by an oblique rib It and openslaterally at both edges of the wheel on opposite sides of said oblique rib, forming inlet and outlet openings, adjacent to which the side walls of the groove project obliquely out from the wheel substantiallly parallel with the rib It, shown at is. A wheel It, arranged at right angles to the grooved wheel K, is secured to one end of a horizontal shaft 76", journaled in hearings in the supporting-bracl et g for the feed-table, and has a circular series of studs k projecting from its face and adapted to enter the groove of the wheel K. As the vgrooved wheel K revolves, for instance, to the left, as

indicated by-t-he arrow in Fig. l, the projecting oblique 'iortion It of the wall of the roovestrikes one of the studs of the wheel and] forces it into the inlet-opening and groove 10:,

thus giving the wheel la a partial. turn. The

stud-wheel remains statitmary while the stud passes through the straight portion'of the groove 7c and given a further movement. in the same direction, when the oblique rib It strikes the stud and force it out of the outlet-opening. A. stud l1 c1 is the inlet-opening'as the preceding one passes out ofit'he outlet-opening, so that the wheel It" and its shaft are intermittently rotated and. held stationary between the movements. The shaft k carrying the stud-wheel, transmits its motion to the shafts h of the conveyersprockets, so as to turn the latter in opposite directions, as by oppositely-arranged bevel gear-wlmels It, secured to the shaft It" and meshing witli bevel gear-pinions k on the lower ends of thosprocket-shafts; The feedconveycr chains areprefera bly covered, except along the center of the i'eedtable, where the cans are placed in and discharged from the conveyor, by plates or shields L', Figs. 2 and 5. These plates protect the operatives from injury by contact with the conveyer and also protect the latter from dirt and dust.

The straightway intermittent feed convever describedis very ell icient in operation. A number of the can-holders are exposed at the receiving end of the feed-table, enabling the operator to place the cans therein with rapidity. The cans and their heads are securely seated in the holder-pockets, and they cannot be dislodged by the movement of the conveyor. The danger of throwing oil' the loose heads and scattering the contents of the cans is much less in the conveyor described than in a rotary carrier. I

M. M M represent the seaming-rollers, whichare carried by the seamer-head and are )resented in succession to the work to re uce the seam. The seaming-rolls perlhrm successive-steps of the seaming operation, and their sha e and number wil depend u on the form of t 1e seam. For instance, in t e machine illustrated, which is intended for forming the double seam before described, one roll M, Fig. 13, has a deep roove m for 3 5 turning the flange 7 on the ca ead aroun'd theiprojecting flange m on the can, as shown in Fig..14. A second roll M, Fig. 14, has an inclined or conical face m, which bears against and turns the interlocked flanges down at an angle, as shown in Fi 15, and a third roll M, Fig. 15, has a shal ow peri )h eral groove m which presses the partially-- formed seam inwardly, as shown in Fig. 16, thereb com leting the seam. Each seaming-roll (see l i s. 8 and 12) is journaled on the inner end a seaming carrier or lever N, which'in turn is fulcruined between its ends on a'pivot-pin n, secured to a second lever or contour-carrier 0.. The contour-carriers are ivoted at their outer ends inthe seamingllead, preferably on hollow journals 19, held in bearing-holes in the top and bottom ring of the seaming-head, and are provided at their inner ends with studs or rollers 1, which travel in a cam groove q in a stationary cam-plate Q, fixed centrally within the seaming-head on the stationary su porting. rod for the upper chuck-head. The camgroove 1 conforms substantially to the she e of the can or box to be seamed, so that as t e seaming-head revolves around the stationary can in the chuck the seaming-rolls are caused to movein a path substantially arallel with retracted when the riers and press sliding plungers t ables a very the seam. During the revolu ions of this 6 5 sea1n1ng-head eachseam1ng-carr1er1n succesl against which is formed on or secured to the hollow sleeve b which loosely surrounds the shaft of the seamingdlead and is clamped in the intermediate bearing-arm c ot the standard A. naled in suitable hearings r in a bracket or casting r, secured to the top of the seaminghead, is a series of three scanner-shafts S, one for each warning-roll. Each shaft is rovided with a worm gear-Wheel s, w iich meshes with the stationary worm R, so as to cause the rotation of the cam-shafts as. the seaming-head revolves. Each seamer-shaft is also provided. at one end. with a grooved cam s, Fig. 11, :into the groove of which extends a stud or roller .9 projectin from one arm of an elbow-lever.s. The el ow-lever are fulcrumed on pins secured in suitable bearing-lugs on the casting r, and the other arm of each lever extends into a'slot in the upper end of a vertically-movable plunger 8,

of which there is one for each seaming-carrier. Each plunger .9 slides in a vertical axial hole in the journal of the adjacent contour-can rier and is provided at its lower end with a conical head or cam which bears against the outer end of the seaming-carrier. (See Figs. S, 10, and 1:2.) The latter is preferabl equipped with a block 3, of" hardened stee confined in a pocket in theouter end of the seaming carrier and made adjustable to compensate for wear by a screw 8 The plungers s are depressed in the proper sequence to oscillate the seaming-carriers and force the rolls toward the seam by reason of the relative shape and adjustment of their operating-cams. The seaming-carriers are plungers are lifted, and their outer ends are 1 ends of the plungers by suitable springs. The springs t employed (see Figs. 9 and 12) are confined. in pockets in the conto'uncarin the {mole ets out against lugs t rising from the outer ends of the sean'iing-carriers. The described worm-gear operating mechanism for the seaming-rollers is very desirable, as it enhigh speed of the seaming-head with very little noise and wear, and iblS simple, strong, and compaet,in construction.

The chucloheads are provided with strip- 'pers or plates U U, respectively, for freeing the can from the chuck-heads after theseaming operation. (See Fig. 7.) The stri perplate U for the stationary chuck-head 1s located in a cavity in the head and secured to vertical rods a, which pass up through holes in the stationary cam-plate Q and have en-' large'd upper ends which rest on coil-springs Arranged around the worm R and jourold against the conical v rods it are preferably equipped with antirested w ile the chuckmovement.

Located in the seam inghead above the stripper-rods u is an annular ope1'atingplate of, liigs. 7 and 8; )rovided with vertical rods or stems it, which pass up through holes in the top of the seaming-head and are yieldingly supported by coil-springs u, surrounding the rods or stems, between nuts or'collars attheir upper ends and the casting 1" on the seaming-head. The operatingplate 11, is depressed to project the stripperplate downwardl to free the headed can when the movable chuck-head lowers after the seaming operation. by tappet-arms on the scanner-shafts, which arms strike rods u,

projecting up from the operating-plate a through holes in the seaming-head. The

friction-rollers for the tappet-arms to strike against. The tappet-arms revolve with the seaminghead, while the stri pper-pl ate is stationary; but the annular operatingplate a which revolves with the seaming-head, is always in position to strike the stripper-rods when depressed, thus enabling the o eration of the stripper without requiring suc i nicety of adjustment as would be necessary without The stri pper-plate U of the lower chuckhead is provided with a'vertical stem or red c, which passes loosely through the lower chuckrod (1 which is tubular. The strippenrod 'u is long enough to project out below the lower end of the chuck-rod, and when the latter nears the end of its downward movement the strip )I-IO(l strikes a stop o and is arrod completes its Thus the chuck-head is permitted to descend below the plane of the feed-table, while the lower -stripper-plate is arrested at thele vel of the feed-table, as shown in Fig. 17, so that the headed can is freed from the chuck-head and supported in the feed-conveyor or pocket at the proper height to he slid oil of the strippcr-plate by the conveyer. The stri per head U remains in th's position until the can to be next headed is slid onto the same by the conveyer and the lower chuck-head rises to elevate the The stop '0 for the lower stripper preferably consists of an ad- 'ustable screw passing through a threaded ole in an arm o projecting from the lower part of the standard A.

The'operation of the machine is as follows:

The seaming-head revolves continuously and the holders of the intermittent conveyer, one after another onto the stripper-plate U of the lower chuckhead D will e the latter is down below the a 17. While the V the chuck to bring the conveyer is at rest the lower chuck-headis raised by the mechanism described and lifts the can upwardly above the conve er against the stationary chuck-head D. While the can and its end or head are clamped and held 70 stationary between the heads of the chuck the seaming is effected by the seaming-rolls acting in succession during the revolutions of the seaming-head B about'the chuck, as before explained. Each roll is held against the seam during more than a complete revolution of the seaming-head about the chuck and preferably during two or more revolutions thereof. After all of the seaming-rolls have performed their functions the lower chuck-head descends, lowering the headed can into the pocket of the conveyer from which it was removed. The can is prevented from sticking to the stationary chuck-head and caused to lower with the lower chuckhead by'the stripper U of the upper chuck head. The lower chuck-head descends below the plane of the conveyer, and the stri per U of the lower head is held up in t e same horizontal plane as the feed-table, as before ex lained, thereby releasing the can from the ower chuck-head. While the can is thus held stationaryon the stripper of the lower chuck-head the intermittent conve er moves a step, thereby carrying the hea from the chuck and moving another can with its loose head onto the stri per-plate of the lower chuck in position to e elevated by tliechuck, as before explained. i The holders of the intermittent conveyer 10c spread, and as the conveyor-chains pass around the sprocket-wheels at the discharge end of the table the headed cans thus released drop into the inclined discharge-chute.

The intermittent straightway feedveyer and its operating mechanism could be combined with seaming mechanisms of different construction, as the actions of the con veyer and can-chuck are not dependent on the particular organization of tie seaming no mechanism, and likewise a different intermittent feed mechanism could be employed with the seaming mechanism described, and the claims covering the construction of the one mechanism are not limited to the par-. 11 5 ticular construction of the other mechanism. The machine as a whole, however, constructed and organized as described is highly of an intermittently-moving 'conveyer proyided with holders for non-circular cans, a 'ehuck for moving a can out of its conveyerholder and holding the can and end station- 12 5 ary, a seamer, a carrier for the scanner which revolves arou nd ithe chuck, and mechanlsm for imparting to said seamer during its revolutions around the chuck a moyement toward seamer into action and i 30 con- 1 o 5 mechanism for imparting to siaid carrier during its re i olutions around the chuck it move-- ment toward the chuck to bring the seamer into action, then a movement parallel with a movement away from the chuck to bring the seain'cr out of action, substantially as set i forth l 2.- In a seaming-machine, the combination l l of an iiit'crniittei'itly-moving conveyor prothe chuck dul'll'lgl'llfll'e than a complete l'ei fi 7 vided with holders for non-circular cans, a lut-ion of the carrier to press the scaii'nand a chuck for inovin 1 a can out of its conveyermovement away from the chuck to bring the holder and holding the can and end stationseumer out of action, substantially as set ary, a seamer which revolves around the l'orth.
