. To nil, whom it'mlag concern.-

Be it known that I, J t'Lit'sBanxztxonn, a citizen of the Lnited States, residing at New York city, Manhattan, county and State of ;.pivot o Xew York have invented new and useful Improvements in Can-Heading Machines, of which the following is a specification.

This invention relates to a machine for forming the seam or joint between a canbody and the superposed can head or bottom.

The l'nachine'niay be readily adjusted to difi'er'ent sizes of cam, is easily tended, and operates with rapidity and precision.

In the aceompani ing drawings, Figure l is a front elevation of in improved can-heading machine Fig. 2, a right-hand end View thereof; Fig. 3, a rear view of the principal parts-of the machine; Fig. 4, a detail of the platform and ga e -operatin mechanism; Fig. '5, a detail'of the table-adiusting llltt'lh anism: Fig. 6, ahorizontal section on line 6 6 Fig. 2; Fig. 7, a vertical section through the table and latforms; Fig. 8, a vertical section through't e seaming-,roller-operatin mechanism: Fig; 9, a vertical section on fine 9 9,

Fig. Fig-:10, a horizontal section on line 1t) 10; Fig. 8; Fig. 11, a section through the H13 )er gear-wheel on line 11 11', Fig. If); and igs. l2, l3, and 14 show consecutive forms of the joint between can body and head.

I The letter (1 represents a can-so porting track flanked at each side by an end ess feed chain 5. The chains b are connected to each 5 other by transverse rods 1) to constitute an open feed apron B. The rods I) extend across track a.and are adaptedpto en age and feed the can-bodies A placed upon tlie tr ack. The chains 1) are held a ainstlateral.Elisplace ment by guides at ant pass over an idler c and a teed-drum d, notched, as at c'. d, to engage the rods 5'. Theidler c is journaled in 3"" table e, to which track ajis connected at. e and which forms a continuation thereof.

Intermittent rot at ory movement is impart-.'

ed to drum (1, and consequently to apron B in the'following manner: The power-shaftftrans' nnts motion bv pulleyj helt f running over idlersf. and hy pulley g toa vertical work shaft g, journaled in 'hearings g of the ma-v chine-frame D; The shaft 9 has a worm g engaging worm-wheel a", fast on spindle d The spindle dtis provided with a crank 11". connected by link (1 to a lever a". turning on To this lever is pivoted a springinfluenced awld", engaging a ratchet-heel i the rotatorrniovement of shaft g is mmcnfast 0 nt rum d. 'B the means (lest-tilled ed into the desired intermittent lmnctili'hl ol' apron B. A detent d engaging tiltt'lltlwheel (i holds the latter ngainst lulzli ion in the reverse direction.

The apron B feeds the cans lugsllltt with the superposed heads A. t! t-l-'-l\'('l upon two vertically-mornl lc platform J. arranged, resectively, underneath l\\n Mls of seaming-rollers j j. Of these the illel t'l j 15 profiled to form a la i-ioim 'hciuwn mmhod) and can-head, whi e' the swarm! -t-t j is profiled to compress the joint intuit tint nirtight seam. The rollers j, as well its the r llersj, are journaled in slides adapted 1" hi 'tate around the can-body and which are rudiall imovable, so as to be brought into op erative engagement therewith. The mean for operating the rollers are identical with those for operating the rollers 3'', so that ill! same description will apply to lmtll. The shaft g-earries a long pinion" g, meshing ltltn two sets of differential gear-wheels it- 1. of whiehlone set is arranged above platl'orin I:

while the other set is arranged ulmvc plat form t'. The upper wheel I: of each set in :1

' smaller number of teeth than the lower wheel I, so that it rotates sh htly quicker than the latter. The wheel s rotatahly supported upon a collar 0 of a fixed shaft 0, having :1 lower chuck o", whichis centered above platform 71 or i and around which the rollers f or j are revoluble. The chuck o is adapted to enter a central depression A. of can-head A. The wheel I has an upwardly-extending hub '1 Fig 8. and is provided with aninterio'r than the lower wheel 1.

- against chuck 0.

ii links The slides N are guided in radial grooves l of a downward extension I of wheel L. Each slide N is composed of an upper section a and a lower section n, adjustably connected thereto. Within a surface groove of the upper section a is attached by ascrew t a countersunk plate n to which pin m IS riveted. An adjusting-screw n, turning in bearings n is received by an opening between parts it and n and engages a thread cut into part a, while it can rotate freely within the upper part of the 0 ening. Thus by manipulating screw n the ower part n, which carries the seaming-rollers 7' or j, may be moved radially inward or outward to adapt the machine to can-bodies of different diameters. After the section n has been pro erly adjusted it is locked in position by e amp-screw n". As has already been stated, the u per wheel It will by pinion g be rotated s ightly faster This excess of movement will cause the cam-groove k to advance slowly over the surface of lower wheel I in addition to the rotary movement common to both wheels. Thus the camrollers we will be moved alternately inward and outward to im art the desired radial movement to slides and consequently to the seaming-rollers j and 7". In assemblin the partsthe cam-rollers m are introduce into groove 7c through openings k of wheel is.

These openings are subsequently partly closed by plates is, that prevent a vertical displacement of the rollers. After the can A has arrived on platform It or i, the platform is raised, so that the can-head A is pressed The means for raising both platforms are identical and are as follows: The worm g of shaft 9 meshes into a second worm-wheel p, fast on shaft p, which is intergeared with cam-shaft p by wheels p. U on shaft 10 are mounted the cams 72 ach 0 which is adapted to oscillate a camlever p, Fig. 4, fulerumed to frame D at p. The free ends of levers p are connected by a rod 1), upon which are mounted two pairs of The first pair of links p is connected to a movable lower plate p upon which is supported by a cus 'on 71 an upper Plate p", having a post p", that carries plat orm h. In like manner the second pair of links 1) is connected to a lower plate p supporting by cushion p an upper plate I the ostp of which carries platform '01. The plat orms h and i are seated Within correspondi recesses of table e and will by the means described be simultaneously raised or lowered. When lowered, their surface is 'a pair of worms s flush with the surface of table 2, While when 1 raised the platforms extend a distance above the table. In order to guide the platforms durin provi ed with depending pins 19, that entheir vertical movement, they are center the can-body A upon the platforms, there are arranged over apron B a pair of longitudinal guide-rails Fig. 6, having diverging ends q'. The rails q are adjustable and should be so set that the distance between them equals the outer diameter of canbody A. Thus the movement of the feedapron will cause the can-bodies A to be centercd in a longitudinal direction between the rails q. Means are also provided to center the can-body in a transverse direction upon. the first platform h. These means consist'of a gage 1", having a V-shaped notch r and arranged opposite platform 72. The gage r is movable at right angles to the movement of apron B, and to accommodate the gage the front rail 9 is partly broken away. The means for operating the gage r are as follows: To plate p is attached an extensible arm r carrying wedge 1", Fig. 4, which is alternately raised or lowered by cam 5 The wedge 1 engages a roller 1', journa fed in hangers r which are attached to age r and straddle a support r", projecting om table 0. W'hen the wedge 1" is raised, it will force the gage r backward along its support r" to center the can-body upon platform 72. W'hen the wedge 1" descends, t 'e gage will be drawn forward by a spring 1".

The table e is vertically adjustable to adapt the machine to can-bodies of different heights. The means for settin table e consist of a shaft s, Fig. 3, having handle s and These worms engage wheels s, Fig. 5, fast on spindles s, journaled at their upper ends in bearings s of frame D. The lower threaded ends of spindles s engage tapped e es 6 of table e, so that by turnmg shaft .9 t e table is raised or lowered. Clamp-screws t, extending through slots D. of frame D, lock the table in position after having been properly adjusted.

The operation of the machine will be readily understood. The can body A, with suerposed head A, Fig. 12, will by apron B be ed along track a and table e and will be gushed u on platform 72, where it is centered. he plat orm is now raised to force head A against chuck 0 after which the can. and head will be subjected to the action of the seaming-rollers j, that rotate around the can and simultaneously approach the same. After a lap-- .am ha thus been formed, Fig. 13, the rollers j recede o liberate the can and the platform h is lowered. The can is now b a mu B pushed upon the second platform 1, w iere the operation is repeated and the seam is closed, Fig. 14, to complete the operation.

What I claim is 1. In a can-heading machine, the combination of a recessed table, with a verticallymovable platform seated therein, a chain for feeding a can-body upon the )latform, means gage corresponding openings of table e. To for raising and lowerlng the p atform, a chuck above the platform, a series of seaming-rollers surrounding the chuck, and means for imparting a simultaneous rotatory and radial g -tion of a wheel having a radial guide, with a movement to said rollers, substantially as specified. l

2. In a can-heading machine, the combination of a track with a eed-apron, a verticallymovable platform, a pair of guide-rails having diverging ends a gage, and means for reciprocating said gage at right angles to the feedron, substantially as specified.

3. 1% a can-heading machine,the combination of a wheel having a cam-groove with a second wheel having radial guides, slides movable therein, seaming-rollers journaled in the slides, cam-rollers connected to the slides means for and engaging the cam-groove, and rotating the wheels at different speeds, substantially as s ecified.

4. In a caneading machine, the combination of a shaft having a chick and a collar, with a lower wheel rotatably supported on the collar and having radial guides, slides engaging said guides, searning-rollers journaled 1n the slides, an upper wheel rotatably supported upon the lower wheel and having a cam groove, cam rollers connected to the slides and engaging said groove, and means for rotatin the wheels at different speeds, substantial y as specified.

5. In a can-heading machine, the combinaslide engaging the same and composed of an up er section and a lower section, means for ra ially adjusting the lower section along the upper section, and a seaming-roller journaled goedsaid lower section, substantially as speci- 6! In-a can-heading machine,the combination of a track with a feed-apron, a verticallyrnovable platform, a chuck above the same, a lower gear-wheel rotatable above" the platform, radially-movable slides enga ing said wheel, seaming-rollers gournaled to t e slides, an .upper gear-wheel iaving a cam-groove, cam-rollers connected to the slides and engagin said groove, and means for rotating the wieels at different speeds, substantially as specified.
