L 35 1,95 1 Patented Sept. 7, 1920.

2 SHEETS-SHEET 2- preferred form is for the formation therefrom of UNITED STATES Application filed January To all whom it may concern.

Be it known that I, JAMES A. GRAY, a citizen of the United States, residing at the city and county of San Francisco and State of California, have invented certain new and useful Improvements in Multiple-Disk-Cutting Apparatus, of which the following is a specification.

The hereinafter described invention relates to an'apparatus for the multiple cutting of gasket disks from fiat liner material gasket ring liners for use in connection with lining of can ends employed in the hermetic sealing of cans or metallic vessels containing food products, the object of the invention being the production of an efiicient, economic and rapidly operating. apparatus for simultaneously cutting from a traveling web of liner material a plurality of disks, the disposition of the cutting mechanism relative to. the traveling web being such that the disks are cut or severed from the web with the least possible waste of liner material and in its preferred embodiment the apparatus employed operates on two continuously traveling superposed webs of liner material, whereby on each reciprocating strokeof the cutting punches of the apparatus there is not only removed or cut a plurality of disks from a traveling web of liner material, but equally so a plurality of disks from a plurality of superposed traveling webs of liner material.

The purpose of the present apparatus is the severing or cutting from a web of liner material disks from which ring liners are subsequently severed by separate or independent mechanism, which cut ring liners are for use in connection with the lining of can ends for sealming tocan bodies or metallic containers.

In order to comprehend the invention reference should be had to the accompanying sheet of drawings, wherein an apparatus of illustrated and described.

of the apparatus, the said frame being provided with a rear or back wall member2 in front of which the webs of liner material are adapted to pass or travel as moved through the machine, the said frame and its backing 2 being in the present case vertically disposed. To the frame 1 and in advance of the backing plate 2 is secured in the present case an obliquely disposed support 3 which is detachably held to the frame 1 and spaced from the backing plate 2 by means of the bolts 4, which secure or unite the bracket extension 5 of the said support 3 to the frame structure 1. The obliquely disposed supporting plate or member 3 is provided with a series of guide-ways 6 formed by the angle plates 7 secured to the said outer face of the said support 3 and within which said guide-ways are mounted for reciprocating movement a plurality of slides 8, Figs. 1, 3 and 6 of the drawings. Each reciprocating slide 8 is united to a driven shaft 9 by means of the pivotallyconnected rod 10 which rods in turn are connected to the crank heads 11 secured at intervals to the said shaft 9. At its inner end each of the reciprocating slides has secured or united thereto in any suitable manner a punch 12, Fig. 6 of the drawings. The crank shaft 9 is driven from a power shaft 13, through the medium of a pinion 15' mounted thereon meshing with the gear 16, secured to'the upper extremity of the said crank shaft 9, Figs. 1 and 2 of the drawings,

the drive shaft 13 being driven from any.

suitable outside source of power by means of a power belt, not shown, working over the belt pulley 14 secured to one end of the said drive shaft. On the drive shaft 13 is mounted a worm pinion 16, Fig. 4 of the drawings, which meshe with a worm 17 secured to a transverse siaft 18 mounted in suitable bearings in the frame 1 and situated in a plane above and at substantially right angles to that of the drive shaft 13. At one end the shaft 18 carries a belt pulley 19, over which works a belt 20 adapted to drive a belt pulley 21 secured to a transverse shaft 22 working in bearings at the lower end of the frame 1. The said shaft 18 has secured thereto a roll 23 intermediate of its bearings and at its end opposite to that carrying the belt pulley 19 is secured a pin ion 24, which pinion meshes with a similarpinion 25 secured to one end of a transverse shaft 26'arranged in advance of the roll 23 and parallel with the shaft 18. To the shaft 26 is secured a feedingroll 27, Fig. 2 of the drawings.

In the present case the apparatus is illus trated as adapted for the carrying or moving of two superposed webs of paper therethrough, the

rolls

28 and 29 of liner material being mounted or supported in a suitable holder 30 arranged a distance at the move over the idler rolls 32 of the support 31,.the free ends thereof extending downwardly between the

feed rolls

23 and 27 and beneath the delivery roll 33, which maintains a tension thereon and directs or delivers the same onto the longitudinall disposed upwardly inclined endless trave ing apron 3 1, the said superposed webs of liner material during their downward course of travel passing between the alined reciprocating punches 12 and the hollow fixed cutting dies 12, Figs. 1, 5 and 6 of the drawings. There is a cutting die 12 for each reciprocating punch 12, each cutting die being arranged in horizontal alinement with its associated punch 12. These dies 12 are secured within longitudinally disposed spaced openings 35 of the fixed backing plate 2 of the apparatus, and project a distance in advance thereof. As the webs of liner material travel between the punches 12 and the cutting dies 12 the said punches 12 coact with the dies 12 on the inwardly .reciprocating stroke of the slides 8 to cut out or sever from the webs of liner material a plurality of core pieces 36,-which core pieces are gradually forced through the hollow dies 12 and the circular openings 35 of the fixed backing plate 2 and move onto the holder or magazine 37, which holders or magazines in the present case consist of a plurality of spaced outwardly projecting rods or supports 37, Figs. 1, 5, 6 and 7 of the drawings. It will thus be seen than on each inwardly reciprocating stroke of the slides 8, there is cut through the medium of the punches 12 and the dies 12 a plurality of disk blanks or core-pieces 36, which cut disks are delivered onto the magazine or holder 37 until a given number has accumulated thereon, which are then removed for action thereon of independent mechanism for the cutting therefrom a gasket ring liner of a diameter suitable to fit the flange of a can end. The disk blanks as cut from the webs of liner material move onto the support or holder 37 against a movable friction block 37 which maintains the disk blanks in vertical position, it being understood that the said block 37 gives outwardly to the pressure of the core-pieces thereagainst.

The superposed webs of liner material are 'momentarily arresting of the downward travel of the webs below the cutting punches, hence a slight buckling of the webs between the feed rolls and the punches, Fig. 5 of the drawings, which buckling is disposed of by the weight of the traveling webs when freed on the outward or return reciprocating stroke of the cutting punches to release the said webs. It is by reason of this momentary buckling of the webs which is provided for, that'permits of the continuous feed of the webs of liner material. The transversely disposed roll 33 acting on the webs at the lower portion of the machine serves to maintain or hold the webs under tension and to guide and direct the free ends of the traveling webs onto the endless traveling conveyer or apron 3a, which apron or conveyer travels over the rollers 38 and 38', the roll 38 being driven by the belt 20, which belt is so run as to train over the

belt rolls

19, 21, 21 and 21*, Figs. 1, 2 and 4 of the drawings.

While the reciprocating slides carrying the punches 12 have been illustrated as extending obliquely to the path of travel of the superposed webs of liner material, it is apparent that such an arrangement is not essential, inasmuch as the said punches may 1 be disposed transversely to the path of travel of said webs of liner material. However, by arranging the support 3 obliquely I am enabled to cut on a single stroke from a web of given width a greater number of disk blanks than could be cut from the same Width of web of liner material when the cutting punchesare disposed transversely to the line of travel of the said webs, and it is for the purpose of securing the cutting of the greatest possible number of disks on a single action of the cutting punches that the punches are arranged in a line obliquely to that of the path of travel of the webs of liner material. In the present case, the construction of the apparatus is such that the superposed webs of liner material move in a vertical path and the .reciprocating punches in a path of movement at substantially right angles thereto, but it is obvious that by throwing the frame structure from a vertical to a horizontal position the line of travel of the webs of liner material would be longitudinal instead of vertical, and in such case the disposition of the series of cutting punches would be relatively vertical in relation to the width of the-superposed longitudinally traveling webs of liner material.

The disposition of the reciprocating cut ting punches is such relative to the travel of the webs of liner material as to permit of the cutting of the disk blanks in staggered relation, thereby causing the least possible waste of liner'material and reducing the cost incident to the production of the disk blanks to a minimum, which is an essential feature in connection with the supplying of can ends lined with gaskets cut from disks of liner material.

While I have illustrated and described the apparatus in its preferred embodiment of interconnected associated working instrumentalities, it is apparent that changes may be made in the detailed construction of the working parts without departing from the nature and scope of the invention and I do not wish to be understood as limiting or restricting the invention to such described details of construction, but on the contrary wish to be understood as claiming broadly for the invention interconnected or associated working instrumentalities for cutting on a single reciprocating stroke a plurality of disk blanks from liner material either during a continuous or intermittent movement of the webs and this irrespective as to whether the cutting mechanism acts relative to a plurality of superposed webs of liner material or merely on a single web of liner material.
