This invention relates: to container capliner'making and inserting mach nes for automatically cutting out resilient llners of'pa per, cork, or similar material, for metal, glass, or other conta1ner-caps, and lnserting the same into the said-caps, the object of the present invention being to accomplish the cutting of the liners and their suloseque'nt'in sertion into the caps at a high rate of speed.

. Machines at present. in usefor lining container caps, owing totheirsingle-acting construction, are slow in production their speed limit being 100'to150 capelinings per minute. By a double-action arrangement and byother features incorporated in my invention, the

present machine can 'beusedrfor speeds of from 200 to 400icaps per minute, ormore, according toathe size ofthe caps and to thematerial and thicknessof the liners.

For the purpose of achieving'the object of L my invention, the present amach 'ne hasthe following parts and arrangement Acontinuously driven cap conveyer upon. which the caps are placed in spaced relation"from a moving feed-beltby an "endless transfer chain, andon which they'are'carried in proper spacing and alignment through the ma.-,

chine; a continuously-driven liner-strip unrolling from a reel of the; lining material and'moved by a pair of feed-rollers'above the cap-'convey'eriat the samespeed as the lat ter and a twin punch-anddie head recipro cated by an eccentric above'the linerstrip, vin the same and opposite direction to thelatter and with thesame linearispeed. The twinpunc'hes: are equipped with plungers' which take the cut liners fromlthe Lpunchesand in? sert them into the caps 3 a The cutting of the liners takes place after the head-movingeccentric disk-has completed approximately three-tenths of its forward turn, or threetwentieths of a revolution, in the direction of the liner-strip travel, when the center of the eccentric disk moves 3' approximately parallel with the liner-strip,

being then near its position of minimum angular variation andmaximum linear displacement. The cutting ,strokev 0f the punches is-completed during-the next one-f tenth revolution of the 1- rdriving eccentric,

whereuponthe inserting plungers start'their downward stroke, completing the-same in" about one-fifteenth of a revolution of the eccentric, punches and plungers reversing i1nmediatelyon reaehingitheends of their downstrokes and emerging from the liner strip.

\ about one-thirtieth revolution of the eccentric; after insertion. The cutting, inserting and wlthdrawal actions thus occupy approximate-'- ly 1/10+1/15+1/30,='1/51of a revolution of the eccentric, during which the cutting head moves at practically the same speed as the liner strip, namely from about one-tenth of a 3 revolution beforeits vertical center position to one-tenth'of a revolution after thisposition.- v i Inthe present machine, therefore,1-double machine. v i

Figs. 9 to 12 are diagrams showing the position of the die-head and of the punches and inserting plungers in the same, at 90, 114, and 180, positions of the diehead eccentric, respectively.

Referring to Figs. 1, 2, and 3, the frame 15 of the machine supportsthe main drive shaft 16,gthecam shaft 17, the fulcrum shaft 18, the sprocket shafts 19, 20, 21, 22, 23. and 24, the pulley shaft 25, the' feed-roller shafts 26 and 27, the idler shaft 28, the reel shaft '29, and the guide-roller shafts 30 and 31.

Shaft 16 carries a sprocket 32 connected by chain 33 with sprocket 34 on shaft 17. A

spur gear 35 mounted on shaft .16 drives the gear 36 on sprocket shaft 19, the gear 36, in turn, meshing with gear 37 on feed roller shaft -26. The latter shaft has the sprocket 38 which, by means of chain 39, Cl1;lVS the sprocket 40 on shaft 23- Asprocket- 41 onshaft 19, by means of chain 42, drives the sprocket43 on shaft 20. e I

. In the bearings 44 of frame 15 are mounted the horizontal shafts 45 on which slides the die-head '46 which is set into reciprocating'lnotion by the eccentric disk' 47' on drive shaft 16 through connecting lever48 pivoted to lug 49 of the die-head. The: die-head' 46 carries thev twin punches-5O into which are fitted the twin plungers 51. The punches 50 are actuated by the eccentric disks 52 mounted on cam shaft 17 ,their hoops 53' carrying 1 strips 54 in the ends of whichthen-head 55 of the twin punches 50 ispivoted; The

; plungers ,51 are suspended from" the lever 56 fulcrumed on shaft 18 by means of the slotted link 57, pivoted to their head 58. The

lever.56 carries the roller 59'hel'd in engagement-with caniGQ attached to one of the eccentric disks 52 on shaft 17 by a coil" spring.

61stretched from pin 62in lever to: pin

'63 in frame 15'. The shaft 17 passesthrough the slot. of link 56 whichslot is made of such size as to clear shaft 17 both in. its vertical motiondue to cam 60 and i112ltS-l1011- zontal motion due to-therec iprocation of the die-head.

The bottom of the die-head is recessed so that a shallow slot is formed above the ledger Y plate 64 which is held against the die-head by the cover-plate 65. Through this slot passes the liner strip S which is drawn off'the reel 66 on shaft 29 by the feed-rollers .67 and 68 on shafts 26 and 27,respecti1vely, One of the"feedrollers, 67, is driven from the "main shaft 16 by the. spur gear 35 meshing with gear 36 Onshaft 19, the latter gear, in turn, meshing with gear 37 onshaft 261 The other feed-roller, 68'is held in tension against strip S by springs 69 attach-ed to pins70 and 71 at the ends of shafts 26 and 27.- The strip S is guided into the feed-rollers by the roller 72 on shaft 30, supported by bracket eX- tensions73 offrame15, and is led out'ofth-e machine by the guide roller 74 on shaft 3L The cap feed is shown in Figs. 1 and 4. The caps are placed on feed belt 75 which runs over pulley 76 on shaft 25, driven from shaft 22 by sprocket 77, connected by. chain 78 with sprocket 79 on shaft 25. Near the end of the feed belt, the caps C are stopped by the proj ection- 80 of timing lever 81 which is fulcrumed on stud 82 and held in tension by. a. spring 83. A transfer chain 84, running over sprockets85 and 86 on shafts 23 and 24, respectively, and d'riven by sprocket 38 on feed-roller shaft 26 through chain 39 and sprocket 40, is provided with two rows of radially projecting. taper-ended pins 87 spaced to correspondwith the cap-pitch of the die-head. By means of the pins- 87 of one row, the chain 84 actuates the timing lever 81 at proper intervals and thereby allows one cap at a time to pass the projection 80;. The

cap thus admittediscaught. by one: of the pins'87 of the other row of transfer chain 84 and carried by the same over" the bridgepiece 88 onto the conveyer chain. 89 on which it drops into" spaced: position, between twopins 90, similarly placed as pins 87 of chain 84. sprockets 91, 92 and 93 on shafts 22, 21,. and

20, respectively, being driven by the chain 42 running; over sprockets tl and 43 on shafts 19'and 20', and? overidlcr 94- on shaft 28-.

As seenby the plan View in Fig. 4, the feed belt and the conveyer chain 89 are in line, the: caps reaching the conveyer chain: being each located in: position by one pair of pins belonging to the same chain link. Thetransfer chain 84', on the other hand, is laterally displaced with respect to the feed belt and;

conveyerchain,v one row of its-pins- 87 coinciding with the center line of the latter'whilereach the transfer point and there is always a plentiful supply of them when the timing lever opens the passagea' Side-guides 95 keep the advanclngcaps inilme during: their progress on the feed belt and conveyer chain, and

supports 96, Fig. 2, between the sprockets 92' and 93 sustain the caps on the conveyerwhil'c the liners are being inserted. i ntothemr The construction of the chains used for transferring and con'veying'the. caps issh'ownin Figs. 5, 6', and 7. The pitch of the; chain is so chosen that a wholenumber of links is required toma-ke upthecap-pitch which is identicalwith the center distance of thetwin punches. the example shown, this number The conveyer chain 89' runsv over the vertical taper-pointed pins 87 (or 90).

is 3, thus every third linkis provided with horizontal extensions 97 to both sides of the chain, these extensionscarryin the nice the number: of links per cap-pitch in this case is an odd number, the extensions '97 are alternately carried by outside and inside links, Fi'g. 6; in case of an even number, all pins would be carried side links.

The operation of the machine is illustrated centric disk 47, by 360.' As the liner strips andthe caps C on conveyer" chain 89 moves forward, the punches 50 descend until, at about 54, when the die-head 46 commences to travel at approximately the same linear speed as the strip and the caps, they engage the liner strip, and cutting of the liner commences. At 90, in the middle of the forward stroke, the punches, after completing the cutting, have reached their'lowermost position and begin to withdraw while, at the same time, insertion of the liners L into the caps C by the plungers 51 commences, the inserting stroke being completed at about 114,

. whereupon withdrawal of the .plungers takes place, the plungers emerging from below the liner strip at about126when the linear forward speed ofthe die-head begins to fall off substantially. The engagement between the liner strip and the punches and plungers in each cycle thus lasts from about 54 to about 126, or for approximately 7 2 or one-fifth of a revolution. While the center of the dieheadmoves at variable speed from a to b,

corresponding to the movement from 0 to 180 of the eccentric, thecaps onthe conveyer I serting machine through which travels a coin move at uniform speed from the position the-caps continue forward to the position cycleis now repeated. V

the position of the the head, caps, punches, plungers, and punchand plunger-actuating parts at the beginning of the die-head stroke, or 0,at the center of shown at (Z to that shown at At the center of the forward stroke, 90, the die-head, as shown at c, is concentric with the caps then in position 6, and its speed has its maximum value which is identical with the uniform liner and conveyer speed. Between 180 and 360, the die-head returns from Z) to a while shown at g, in which two new caps 'shownby dotted lines have justentered' into starting position under the die-head (corresponding to the position of the old caps) so that the Figs. 9 to 12 show the forward stroke, or 90, at the end of the insertion stroke, or.114,"and at the end of the forward stroke, or 180, of the die-head eccentric respectively. In Fig. 11, the insertby extensions o'fout ing plungers- 5 1 are in their lowermost posi tion, the roller 59 having descended from its upper to its lower position between 90 and 114 'while the cam 60 has advanced by 7 24. After a further advance of 12, the roller will have returned to high position so normal level above the liner strip. 7 a

At 0, Fig. 9, bothpunches' and inserting plungers are above the liner strip S, so that the latter, whiohthentra'vels faster than the die-head,is not interfered with the former.

At 90, Fig. 10, the punches are at the end of their downward stroke, having "cut the liners p L from the strip S, the cam 60 i-sat the end of its circular dwell, and the caps C are concentric with the die-head. At 114, Fig. 11, the cam-roller 59 is down, the liners L are in- 'serted in the caps C which'are still concentric with thedie-head, as from'54 to 126 th latter has the same linearfspeed as the 0011- I that at 126 the. plungers are again on their veyer, and the punches 50 have startedon v their upward stroke. At" 180, Fig. 12, ii-

nally, the die-head 46' is'inits extreme for- Wardposition, ready to begin its return stroke, and the caps C,v which have 'com-' menced to gain on the die-head at 126, are now well in'advance'of the same and continue their. forward motionwhile the die head re-" V turnsfto its starting point. At 360, the the head has returned tothe position shown in Fig.9, the cap-conveyer has moved a distaiice equal to twice; the cap-pitch, so that j now thenext' two caps on the conveyer will be operatedupon. In this manner, the new twin machine accomplishes twice the work of an ordinary machine running at the same speed. Forv still greater production, three or more punches may be comb ned in o'ne die p head in, a similar manner,
