Specification of Letters Patent.

Patented Aeg. 17, 1909.

Application filed July 22, 1907. SerialNo. 354,961.

To all whom itl'mng/ concern.'

.Be it known that we, BnxJAiiiN .thermen f i and Anios OnLLnsoN, citizens ol the linited e States', residing in Brooklyn, eountyoi liings,

State of New York, have invented a certain new aiidrusefull Machine for (ilenchingI rlogether Sheet-Metal Cans and lheir Heads: and we do hereby declare thi` lollow ing to be a iull, clear, and exact description oi' the invention,- such as will enable others skilled iii the' art to which it appertains to make and use' the saine, reference being had to the accomp anying drawings, and to characters of reference marked thereon, which form a part of this specification.

Our invention relates to can heading machinery, and it consists in certain improvements ,in such machinery having .,or their object to provide means lor automatically machine of, say, the type illustrated in the application for U. S. Letters Patent iiled February 28, `1905, #247,766 andA which it is unnecessary to describe herein more particularly than byA stating that it comprises Vlfour heading units between each two of 7 clined planes lor chutes down which the cans which, at two points in the machine, the cans are fed .to be alternately distributed to said units -for heading. In the application referred .to it was roposed that the cans be introduced into t e machine by means of in- `moved by their own Weight; this construction required, however, an incline oi' such n. pitch that cans 'filled or partially filled with liquid would lose considerable of their contents before they reached the heading means. By the present invention it is proposed to not only leed the cans along a substantially horizontal plane but to also provide. l'or preliininarily rand temporarily clenching the heads thereon so as to prevent loss Oi' their contents during`- the feeding operation, it being remarked that the type of can which is particularly in mind is that y,in which the cover o crates as a sort oi' a wedge onthe can boi y when thetwo are assembled and thus forms with the latter an adequate seal for the time being. l

The invention will be l'ound fully illustrated in the accompanying drawings, wherein, i i

Figure 1 is a vicw in side elevation oi' the machine assembled'with a multiple heading machine of the type illustrated in the application aforesaid; Fig..2 is a slightly enlarged top plan view oi' certain parts shown in Fig. 1, others being removed g F ig. 3 is a side view ol the main part ot' the machine, looking Ifrom the riolit in, F i0. l certain arts bein removed; Fig. l is an enlarged iront view of the upper portion oi' the main part of the machine ;-Fig. 5 is a side view, looking from the right in Fig. 4, oi' what is seen in Fig. 4; li'ig. 5 is a horizontal sectional view on the line aff-1 of Fig. 5; Figs 6 and 7 are a l'ront view and a top plan view of a certain platef; and, Figs. 8 to 24, inclusive,rillustrate details, Figs. 8 and 9 being plan and iront views of a bracket for sustaining certain belt supporting plates; Figs. l() and l1 being top plan and front views of other brackets for said belt supporting plates; Figs. 12 and 13 being `top plan and -front views of a certain switch; feeding the cans and heads to a headmgf Figs. 14 and-15 being top plan and front views of the can head plunger and clencher;` Figs. 16, 17 and 1S being, respectively,a top plan, underneath, and end view of the plunger and clencher with all accessories Iable means to the several heading units."

d is a pedestal arranged back of the inal chine a and formed on one side with a dat face e against which is bolted a )latef partly supported by the pedestal and by a le g. 'llic plate f affords bearings for a sliaipt 7i' carrying a sprocket wheel 'i and a ear wheel j; said platestands at right ang es to the machine a and.I at its farther end it carries 1 another shaft c on which is journaled a drum l. Over the' drum and sprocket wheel extends a ychain 'conveyer `m each of whose links isa block n having oneY end bifurcated and receiving the unbifurcated end of the next link, the two bein joined together by a ,pin o; the topof the b ook a is not flat,but 1s convex, as at p, Fig. 4 `the reason for this grows'out of the fact that since the can has a depending lower flange its lower wall wouldbeiotherwise unsupported during the head appl ing operation so that the pressure ofthe can cad. applying device would cause the bottoni to bulge and thus produce an unmarketable can. The unbifurcated end-of each link is formed as an.. upwardly projecting finger g. The cans are placed on this conveyer with the head loosely resting on each,

eachbetween two lingers 1 and disposed lengthwise on the conveyer.

Above ai@ pisa f there is balada ai@ flat face e of the pedestal d another plat/e 1^ formed with a bearing s. In this bearing is journaled a shaft t carrying at one end a cani. u and at the other end a sprocket wheel ci..

In the plate rist'ulciuined, onstuds a pair of levers z acting as parallel levers by virtue of being pivotal connected by a link l..

' 2 isa plunger lock having-a rear flat face 1 bearing square .against the levers. z, the same being carried by an adjustable pitinan 3 suspended from a crank pin 4 on the cam a.

In the back ofthe plunger block 2 is a dovetailed groove 5 in which works, vertically, a

i' slide 6 Which is pivotally connected, by studs 7, to the free arms of the levers 2.

8 is a roller journaled on the stud on thel upper lever z inposition-tobe engaged by the periphery ofthe cam u. T e mechanism above 4partially described and best shown in Figs. 4 and 5'operates substantially as follows: In the rotation of ,shaft t cam uis brought against roller 8 while lherotation of the crank-pin is causing the plunger-block 2 to ascend; since the cani and upper llever z have different centers of rnoven y nient, the action of the carn on the parallel levers 2 is `to cause them to swing on their the cam continues to turn.

and until art 19`eomes within the path of a' "linger q, Wien cam u recedes from roller 8 as During the lat ter ,art of this operation7 the plunger block, whi ev s tilll descending, being allowed to I more by'gravity to the right, thus following 'thernoveine'nt vot-the can, which is being cor-l respondingly nioved iin'ger g, luid the iplunger block` continues this movement untill the stud 4 Qreaclniesfits' lowest liinit of inoveinent,`wher eupo`n 'it'bcgns to rise. In its rise, after itclea'rsiingei" q, it of coursehas a vertical movement; aswell as, again, to the left. It will thus'lbe's'een that the plunger block accommodates "itselff to the? advance lof the conv eyer m as it descends, moving-to theright and thus with-the conveyer while the'headiapplying operation is proceeding.

Thusvit is `unnecessary tostop the conveyer 'bending devices to their ncrinal or openposievery time a head is applied, so that the operation is not only quickened but the jarring of the cans, from alternately starting and stopping, prevented.

The plate f is formed with a shell' 1'0 on which the up er stretch of' the conveycrm. rests. The pliite itself forms the back wall of saidshcli against which the cans rest when they are placed on the conveyor; when they are ready for thc head applyingr operation, i. e., about 'opposite the pedestal d,-

they pass in behind a lront wall l1 secured lo thc shelll 10. Said front wall and the opposed portion'of the plate f have opposed groovcd guides l2 which receive the llanges of the head and body, (see Figs. 3 and 5) when the can and head are assin(T the ied-v estal.

The plunger comprises, together with thev block 2 above dcscri ied, a means for pressing the can heads against the cans and for clenching the head and can edges, 0., bending thesarne over together in relatively limited portions so that the can and head are suflciently interlocked lfor the time boing` so that the head will not bcconi'e dislodged duringT the subsequent treatment. Said moans is illustrated in detail in Figs. 14 to 24. 13

is a block attached to the under side of the plunger block 2 by bolts 1'4. At opposite points it is provided with vertical grooves 15 1n which ar`e`secu1ed, by screws 1G, wedge pieces 17. 18 designates four vertical holes in said block. block 13 and 'movable' vertical y relatively inglscrcws 20 which penetrate the holes 18 in block 13 (having then' heads 1n countersinks 19 yis avblock dis osed below thereto, the same carrying upwardly extend- 21 of the latter) whereby they guide the block 19 in its movements; springs 22 intorposed between thel two blocks 'and coiled about the screws press the block`19 downwardly to the linit alfordcd by the heads ol the screws. The block 19 is formed on its under sid'e with a groo'vc23 and a groove 124 Countersunk therein; in'tlic groove 23 is arranged a pair of slides 2.5 pressed apart by a spiral spring in. the groove 24. A :plate 27, secured to the under side of the block 1l) by screws 28 arranged in the holesQQ, keeps the spring 26 in place even though a rplate 30, which is secured by screws 31 to the block,

tions. In order to prevent the screws 2() roin turning,l their lower ends are recessed, as at 34, to receive keys 35 set in grooves 36 in the iio under side of the blockand held in place by the plate 80. When the lunger block descends and the block 19A ears against the head of the can the pressure efl'ects a rela tively upward movementof said block in the,

shown a groove 37-in Figs. 15, 22 and 24.

The end of the plate f adjacent the machine a is formed as a bearing 38 in which is journaled a shaft 39 carrying yat one onda spur Wl'1eelf40 meshing with thev sprocket wheel j and at the other end a peripherally .grooved cam 41. Above vthis bearing.: the fplateis extended and formed with a small table 42 on which is secured a bracket 4S. 0 l(ln this bracket and two brackets 44 (sei Figs. 2 and 10), which latter are secured to the platform c of the machine ai, rest the ends of belt supports 45, the same-,being countersunk in the tops ofthe brackets. In the bracket 43 are journaled two rollers 46 set with their axes at right angles to the belt supports 45, Whichoccupy a' position in the form of the letter V as `seenin Fig. 2; correspondingly, in each bracket 41' is journaled a roller 47. Over each roller 46 and the correisponding roller 47 extends an endless belt 48, the upper stretch of which rests on the belt lsupport 45.

49 is a vertical shaft journaled in the (i5 bracket 43 between the belt supports and limited against ,vertical movement therein by a switch ,5G on its up er end and a crank 51 on its lower end, a ro ler 52 on the crank "being engaged in the groove of cam 41. As hereinafter explained, the cam 41 Oscillates shaft 49 throughthe crank 51 and thus.l

vibrates the switchin such manner that the cans are fed on to the belts 48 alternately as' they come from the clenchingoperation. When the cans 'finally reach the niachme c they are intended to' do so side oh, a can inarked A being so" shown in Fig. 2; when the cans leave the clenching operation they move endwise, and in order to effect their change of position so to stand side on on the belts 48, the switch 50 lhas its freel end formed as a blade 53 havin converging side edges 54. A more particu ar descrlption of the manner i'n which the cans change their position will follow later on.

Inrorder to guide the cans they are conveyed by the belts 48 to the machine (L, .tlat sidezstrips 55 are provided, the same being supported by spacers 56 orrth'e belt sup- 60 ports 45 and blocks 57 secured to the sides -oi' said belt supports. These strips stand high enough` from the belts 48, which they overlap,` so that the lower can edfres just "about itbetween the belt and sai-d The edge Lo engagmg portionof each bendmg ferire '1s y p strips,v 6.5 vallowing for slight variations in the thickness of the edges ol the caps. Jamming of the cans is efectually prevented as'they are about to more on to the Aplatform c ol' the machine a by a guide 5S which extends longitudinally over each belt 48 and close enough'to the same so to keep euch can squarely against its belt, said guido being carried by arches 50. f

6() arc entrance guides gi'ooved on their insirlea, as at 61, to accommodate the lower flanges ol' the cans, and arranged on tbe bracket 43.

ln order to keep the belts 4S taut, a

,weighted roller 62 journaled in'a lever 63 lult-.ruined in each` bracket '44 is arranged to rest on the lower stretch of the belt. Each belt is driven from a pulley 64 on the shalt Z) I of the machine e by a belt 65 extending. around guide rollers 66 andY then around a pulley 67 on the shaft of the roller 47.

68 is a chain passing around the sprocket wheels j and u and also aro'und a sprocket wheel 69 on shaft b, the same acting, through mechanism already described, to drive the conveyer m, re yiprocate the plunger, and vibrate the switcih 50.

When the cans and heads have been operated upon by the clenching means the conveyor 'm advances them successively on to thebracket 43. The switch 45 vibrates as fast as each can approaches, first to one side and then to the other. The center of movement o'l the switch, c'. e., shaft 49, is alined with the centers of the approachingr cans so that,l according as the extremity of the switch is at one limit or the other, so the blade 53 is opposite the one or the other ol" the further corners of the nearest approacln ing can. As this can is advanced by the conveyer m causing the cans behind it to feed it forward, one of the farther corners thereof is engaged by the blade 53, which now moves and, since it has contact theiewith in its rear part, displaces' the can laterally in such manncr'thatit sinmltammu::ly turns ,it until the adjoiningl edge 5?, olA the blade rests squarely against the side ol' the can, whereupon the switch directsl it i nto, its properposition, side on, on the belt 48. Once on the belt, it is carried forward therw by to the machine a, the same operation then occurring witl'r respect to the can behindit.'
