"Application filed April 16, 1914/ Serial No. 832,261.

To all whom it may concern:

Be .it known thatI, JAMES A. GRAY, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Apparatus for Cutting and Applying Ring-Liners, of which the following is a specification.-

The present invention relates to an apparatus for the cutting from a disk blank an annular or ring liner for'use in applying to the circumferential flange of can ends or covers, the object being by a single operation of the cutting mechanism to properly trimthe disk blank, to sever therefrom the de sired annulus or ringliner'and at the same time remove the core-section thereof, thereby accomplishing by a single acting punch means that which heretofore has required the action oftwo punches to successfully carry out. v

Usually, in the cutting of ring liners. for

the flange of can ends or heads. a traveling web is emploved'from which the annulus to be removed or severed is first presented to the action of a punch for removing there. from the central core. andth-ereafter the said web is acted on by a second punch or die of a diameter slightlv larger than that of the first punch or die for the removal therefrom of the annulus or ring liner. It

is the employment of this intermittent-- traveling web that the present machine successfully overcomes, permitting the utilization of disk blanks for the cutting of the ring liner therefrom and bV so doing simplifying. the construction of the apparatus,

. reducing the expense incident thereto to a minimum and at the same time materially increasing the output of ring liners- To comprehend the invention, reference should lie had to the accompany ng sheets of drawings, wherein Figure 1 is a side view inelevation-of the improved cutting apparatus. illustrating the same as applied to means for receiving the cut annulus or ring liners and can ends or covers and for applying the'said liners to the flange of the can ends or covers. also disclosing the means for actuating the various working parts of the said cutting apparatus.

the feed mechanism for the diskblank heing disclosed. Fig. 2 is a longitud nal sectional view taken through the reciprocating die punch mechanism and the stationary associated' die, disclosing in part section one of the pocketsof a rotai vdisk carrier for receiving'the cut annulus or ring liners, the means for feeding the cut annulus therein, and the reciprocating 'plungers working within the said pocket for applying the said annulus to the flange of a can end or cover, saidview also illustrating the manner ofv disposing of the central core removed from the disk blank during the operation of cuttingthe annulus or ring liner therefrom. Fig. '3 is a plan .view disclosing the sizes and positions of the centercore, annulus or ring liner and the trimmed waste relative to the disk blank from which the annulus or ring liner is to be severed. Fig-i is a plan view partlj in section of the stationarv die. the reciprocating die punch and the .parts associated therewith, the same being tracting means partly in its inward posi-- tion. Fig. l is avertical pai'tsectional view taken on the irregular line Fig. 1 of the drawings. disclosing the picker 'or extracting means as'having removed and re leased for discharge the trimmed waste material of the blank. Fig. 8 is -a view similar to Fig. 1'' of thedrawings, illustrating the position of the picker or extracting means as about to engage the .waste of the blank for removal. Fig. 9 is a perspective view of the trip means forac'tuating the nipper finger or aw of the'picker or extracting means. Fig. 10 is an enlarged detail part sectional view ofthe mechanismfor removing the disk 'blanks successively from the stack within the holde and for delivering the same to the feed runway for the posi; tioning thereof relative to the cutting mechanism. Fig. 11 is a plan, view of the parts disclosed bv Fig. 10 of the drawings. Fig. 12 is a vertical sectional view taken on line y --2 Fig. 10 of thedrawings.

- In the drawings, the numeral 1 is used to designate any suitable formof a supportingfraine capable. of sustaining the Working through which respectively the cut annulus parts of the apparatus, which frame is provided with a bed plate 2. Within the frame 1 and secured on a longitudinal shaft 3 working in bearings 3 is situated a vertically disposed carrier disk 4, the said disk.

, volves, and during the rotation of said carrier disk the plungers-6 and 6 are moved toward andfrom each other for applying the hereinafter described cut ring liner onto the flange of a can end or cover held therein, Figs. and 1 and 2 of the drawings.

Each of the circumferential seats 5 of the carrier disk' lis intersected by the spaced segmental peripheral openings 11 and 12,

or ring liners and the can. ends or covers are delivered intd the said seats 5 in spaced relationto each other between the opposing faces of the plungers 6 and 6, the can ends, heads or covers 13 being delivered into the seats of the disk carrier through the opening 12 in 'glny. suitable manner.

thebed 2 and within a longitudinal guide-way 14 thereof works a reciprocating slide 14 carrying at its inner endqtwo concentric die punches 15' and 15, there being interposed between said punches a longitudinally movable die ring 16, which die ring registers with the opposing stationary die ring 17 held to the ring 17 of the cylindrical magazine 18, when the reciprocating slide- 14 carrying the die punches is moved inward its full distance. The stationary die ring 17 is embraced by the follower ring 18' held to the fixed base ring 17 by the collar 19, the said follower ring being normally held outwardly pressed by the springs 19 interposed between the base ring 17 and the bottom face'of the follower-ring, Figs. 2 and 4 of the drawings.

On a bracket 2' upwardly proiecting from the bed 2 is mounted at oneiside of but adjacent to the punch mechanism, a holder 20 fo the stack of ho zontally disposed fibrous d sks 21 from which the annulus or ring liners are to be cut1'.Figs. 1, 10, 11.and 12 of the drawings. The holder 20 is an open bottom one, the st ck of disks 21 resting on the shelves or ledges 22 thereof, and the same are removed successively from within the holder by the hereinafter described sucker-arm. outwardly projecting from a rock-shaft 20". This shaft works within a suitable bearing and carries at one end a;

pinion 21, which meshes with a bevel gear action by the movement of the shaft 20 is a it sucke; arm 31, which is connected by an air connection 32; to suitable suction means. As the arm 31 isthrown upwardly against the under exposed face of the lowermost disk of the stack of disks held within the holder 20, the air suction causes the same to adhere firmly to the said sucker arm, so that when the arm 31 is lowered or swung downwardly,

the lowermost disk of the'stack *of disks 1s removed from within the holder 20 and delivered into the vertically disposed feed chute 32. The air suction is destroyed as the arm- 31 reaches its lowermost position, so as to release the removed disk, said air connection being broken by the port a in'its hinged connection moving out of registry with the'open port b (Fig. 11), thus destroying the air suction through the hollow sucker arm 31-and allowing air to enter between the disk and the edge'of the sucker, and the removed disk blank to fall from the open end thereof. The disks 21 are thus successively removed from the holder and delivered into the feed chute 32 and by said chute discharged into the semi-circular seat 33 for positioning between the faces of the reciprocating die punch and the fixed die,

being held thereto against lateral displacement by the weight of the light hinged holder 33Figs. 7 and 8 of the drawings. At the same time the deposited disk is prevented from falling from within itsseat by means of the laterally movable slides 34rand 34, which are moved inwardly and outwardly during the reciprocating movement of the slide 14 by means of the horizontally swinging fulcrumed arms 35, suitably connected at their forward ends to said slides.

The slide 14 has reciprocating motion inf-st parted thereto from the drive shaft 2s'by means of the crank connection 14 Figs; 1 and 4 of the drawings. By reference to Fig.

' 1 of the drawings, it will be noted that the motion of the drive shaft 28 is transmitted is forced against the fixed die 17; while the concentric punches 15 and l5 mov ng .'in,

to the shaft for actuating the earlier disk 4: through the medium of the intermeshing gears 37 and 37, the' gear 37' imparting Jmotion to a cross shaft 38 carrying a worm 38 which meshes with a worm gear 39 on the shaft- 3', the construction of the worm-' 38being such as to impart intermittent-rotation or movement to the 'worm gear 39.

Referring to Figs. 2, 4 and 5 of the drawings, it will be noted that the die ring 16 is provided. with a.series of rearwardly extend- 1ng-pins 16, which extend through bores" 16' in the circular shoulder 16 of the slide plunge-r 1-1, said pins bearing against. an

workin 'within 'uid'e' bearin s 17 u wardl a a a f y.

projecting from the bed 2.

The-drive shaft 28 is driven in any suitable manner and on the f-n'wardstroke of the slide plunger-.14 with the disk blank 21 positioned as in Fig; 4 of the drawings, the

arms 35 are actuated to move outwardly the slides or slide. plates 34 34 and the disk wardly beyond the peripheral edge of the said die ring 17fcut or sei 'e-r from the disk blank 21 the. central core A, the annulusor ring liner B and the waste ring or trimming C, the cut annulus \or ring liner beii'ig lheld between the opposing faces of'the the rings- 16 and '17; during which cutting actionthe follower ring 18 giving inwardly, tl1e cen'- tral core A is forced into] the die ring 17 by the cutting punch 15 for gradual delivery into the magazineiS by the accumulation; of core pieces. On thereturn stroke of the sa d reci-prrcating shde plunger. the waste rin or trimmin C of the cut disk blank is forced from off the fstationa iry die ring 17 by the action'of the spring follower ls'j while the cut annulusjoraring lineriB- ada hering to the faces of the' die punches l:" -15-- and the die ring l6 is "carried outward beyond the scat and in line with the d scha ge opening 33?, when the eiector ring 17 act1ng against the spring-held pins-l7- gradually mores the die" ring 16 outwardly toforce the cut annulus'or ringliner B clear of the die punches 15 and 15. permitting the same to fall through the outlet opening 33 to within the sphere of the transve sely horizontally dis sed feed rollers 40Figs. 2 and of the dra lags. The said feed rolls are mounted on the parallel shafts 40'-41,'

driven by the inter-meshing gears 42, rotary motion being imparted to the shaft 41 froinj Lhe driven shaft 38 by the drive belt '42 working over the belt. pulleys 43-43 mounted on the shaft 4i and respectively,Fig. 1 rollers 40 deliver the cutannulus or ring of the drawings. ,The feed be disposed of. and for this purpose there is provided a reciprocating nipper or extracting device,icomprising in the present case an arm 23 depending from the rockershaft 23'Fig. 7 of the drawings.- This arm is inwardly curved at its lower extremity and si idcurved extension 24: at its end has pivoted thereto a. spring held nipper jaw ES -Figs. 4; 6, 7 and 8- of'the drawings.

The-lower end of the swinging arm 23 is supported by the curved bracket 26 laterally projecting from the frame bedl2, and as the said arm is thrown inwardly the tail extension 25' of the nipper jaw 25"" rides on theincllined face of a pivoted, cam 27, for gradually throwing thetail extension 25" inwardly to open the jaw 25 so as to' permit offthe said jaw and the extreme end portion of the extension 24 to embrace the peripheral edge" of thewaste ring 0, Figs. 6 and 8 of the drawings. The lip on the follower 18 has a cut out portion, as shown in Figs (i'and 7, to allow of the described action of thenip'per.v The tail extension 25" moving oil of or out of contact with the cam ,27 on the arm 23 being swung inward its full distance, thepressure of the spring 28 thien exerts itself to force outwardly the tail ex ension25 to close the nipper 25" to clamp tie \aste ring C, while at the same time the spring 29" acting against the cam 27 wingslits free inner end outwardly to clear he. depending section of -the tail extension of the nipper jaw. fith the waste ring \or material" C thus clampedy, the saine is removed and withdrawn from kits seatduringthe outward throw of. the arm2 3 being '30 carried until 'the depending section of thetail extension of the nipper jaw engages with and rides againon .the inner face of the cam-bracket 26-" {Fig.lhwrhen the said jaw is opened and the waste'ringC released for-deposit at any suitable place 1' Fig.7 of the. drawings. During this removal of the waste ring or trimmed portion C of the disk21, the pi"-' oted holder or retaining guard 33' gives to the 'n'essure exerted thereon, swinging upwardly to permit ofthe tr mmed portion C being withdrawn. As the arm 2.3 swings outwardlyits fulhdistance the depending section of the {tail extension 25 of the nipper j aw moves off or out of contact with the inner face of the cam. 27?, permitting the said cam to. return to normal position.

The core sections A whichaccumulate w? thin the magazine are removed therefrom aud ted into a machine similar to the one,

- die plunger, of concentric die'punches carherein described and from each of which is cut an annulus or ring liner for use in connection with can ends or covers of less di ameter than the ones to which the present annulus or ring liner is to be applied.

The working stroke of the cutting mechanism, the action of the-feed means for sue cessively delivering disk blanks thereto, the removal of the waste material, the feeding of the cut annulus or ring liner to the mechanism for applying the same to the flange ofcan ends'or covers are so regulated with respect tov each other, that the various de-' scribed actions successively come into 'play at predetermined moments, each part performing its desired'work at the proper moment with respect to the other workingparts of the apparatus, thereby constituting an automatic machine for the cutting of an annulus o r ring-liner from fed di'sk blanks'by a single stroke ofthe die'punch mechanism.

By the described apparatus, the necessity for employing an endless web for the cutting therefrom of the ring liners is obviated, equally so the complex mechanism .for controlling and regulating the feed of such a web is.dispensed with, .and the cutting and feeding of the ring liners is performed with greater speed and accuracy than possible where a continuous traveling Web is employed. J

It will be understood that the expression ring liner is not limited to an annulus, but merely to designate a cut liner of proper shape to conform to the flange of the can end or cover to which it is to be applied, hence the term disk blank as herein employed is -meant to express a blank. of suitable shape from which the desired liner is to be cut.

The present invention is not limited to the details of working parts as herein shown and described, for, these may be varied and modified without departing from the nature and spirit of the invention, and, therefore, I do not wish tobe understood as confining myself to i the disclosed arrangement of working parts, but, on the contrary, desire to cover as far as theart will permitfthe combination of working features for carrying out the described opera'tions.
