Be it known that 1. 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 Methods of Cutting and Applying Ring-Liners to Can Ends, of which the following is a specification.

T he hereinafter described invention relates to a method of cutting ring liners from fibrous disk blanks and applying the same to the flange of can ends or covers employed for the sealing or closing of metallic can bodies and more especially those commonly termed sanitary cans, the steps of the method residing in applying a disk blank within the orifice of a conveying member, transporting the blank by the movement of the carrier member to aicutting station, cutting from such blank a central core or disk and leaving a cut ring liner of proper size within the orifice of the carrier, advancing the cut ring liner by the movement of the carrier to a feed station for can ends and positioning an end or cover plate with respect to the orifice containing the said cut ring liner, transferring by the action of the carrier member the said ring liner and can end to assembling means where the can end'is moved within the orifice and the out ring liner applied thereto while the ring is within the orifice of the carrier member, and finally discharging the assemoled parts from the said conveying mem er.

Any suitable form of mechanism may be employed for carrying out the described method of cutting ring liners from fibrous disks and applying the same to can ends or covers, but preference is given to the appa ratus disclosed by the accompanying drawings, wherein- Figure 1 is a ratus disclosing positions of the the carrier for receiving the disk reciprocating means for front elevation of the appain general the respective feed for the disk blanks,

In the drawingsthe numeral 1 is used to designate any suitable form of a supporting frame capable of sustaining the working parts of the apparatus. and within which frame is secured porting table or disk 2; through a bearing 3 depending therefrom one of the can end with a stationary supdisposed driven shaft 4. To the upper end of this vertical shaft is keyed or otherwisesecured a horizontally disposed turret or carrier member 5, which is held a slight distance above the. stationary table member 2. An intermittent or step rotation is imparted to the centrally disposed shaft i and the horizontally disposed member 5 by any suitably nism, preferably by meansof a mnltilated worm 6 on a horizontally disposed shaft- 7 turret or carrier driven mechameshing with a worm gear Ssecured to the lower end of the said vertically disposed shaftl-Figs. 1, 2 and 3 of the drawings, the said shaft 7 working in suitable bearings located in the structure 1.

ered to the rotatable turret her 5 from a. stack of such within theholder 12 situated at one side of 115 of the turret or carrier with its guide-way 15 in line with the lowerfeed slide 36, which portion 36 of the lowermost. disk let of the stack of disk through a'cu't out section of the stationary. table or platform'2 and conveyed by any.

suitable means toa place of desposit.

The, disk blanks 14 are successively delivor carrier memthe machine, while the can ends 13 to be lined are delivered onto the table 2 and within the sphere of a properly positioned onfice 15 of the said turret 11 ;'situated at the opposite side of the machine. The disk blanks '14 are successively delivered into a properly positioned orifice 5 when at rest most disk of thestack contained within the holder 12, by means of the reciprocating works within a guideway'of the bracket 10. During'the inward stroke of the feed slide the shouldered end thereof engages with the edge blanks and forces the same inwardly through the guide-way 15' into the positioned orifice of the turret or carrier 5. v Reciprocating timed movement is impartedto the feed slide 36 by means of a lever" 37 fulcrumed to a bracket 38 projecting from the frame of the machine.

The .fulcrumed lever 37 is connected by a ,link rod 39 to an operating lever 39 fu-lcrumed 'to'a braeket 39 secured to the opposite sideof the machine from bracket 38.- At its lower end this lever'39' carries a secured to one end of the drive shaft 7. The rotary motion of the said shaft is thus transmitted for im-' par-ting reciprocating motion to the slide'36 and to the feed slide 42, to a depending extension 42 of which slide the upper end of the fulcrumed lever 39 is connected by ashort link 43,. and to the upper face thereof is attached a feed blade 43 Which blade on the inward movement of the slide 42 engages with the flanged edge of the lowermost can end 13 of the stack of ends contained within the holder 11 and moves the same. therefrom onto" the table -'or platform '2yto a position immediately beneath and in alinement with the posiwardly moving within the guide out out 13 disks contained or carrier '5 from a stack of such ends contained within a holder feed leaving a cut ringlmer on the seat in the under face of the said turret or,

member leading to the positioned opening 15, the'circumferential flange of the can end whenso positioned being partly embraced by the wall of such guide cut out.

For the removal of the lowermost end of the stack of can ends 13 within the holder 11 and which end rests on the'bracket 9, it is required that the entire stack of ends with the exception of the lowermost or bottom one thereof be raised a slight distance,

and for this purpose a pair of spaced spring held cut out arms Hare fulcrumed to the upper face of the bracket 9. These arms are forced together for a lifting of the stack of ends, by means ofthe inclines 14' on the longitudinally reciprocating feed blade 43' during the inward movement of the slide 42" acting against the rolls 45 depending from the inner end portion of each fulcrumed arm 44 and by so doing swinging outward or separating such outer endportion ofthe arms and forcing together or closing the inner end portions thereof, and causing the same to enter bet-ween the lowermost two ends of the stack of ends contained within the holder 11 and raise the'entire stack with the exception of the lowermost one thereof. With the continued inward movement of the blade 43, the cut out or released can end is removed from within the. holder 11 and moved onto the table or platform -2 into a position immediately beneath the positioned orifice or opening 15 of the turret or carrier member 5.- On the outward movement of the blade 43 the laterally swinging arms 44 remain in their closed position until the inclines 44' of the said slide are carried beyond the rolls 45, when thetension of the spring 46 draws together the outer end .portions of the laterally swinging arms, separating the inner portions and withdrawing the same from beneath the stack of can ends and by 'so doing lowering the said stack within the holder to position the bottom one thereof for removal on the next inward stroke of the blade 43'.

The action of the respective cooperating mechanism of the machine for carrying out the method is'such that a disk blank is first fed from a stack of blankswithinthe holder- 12 into a positioned, vertical opening or orifice of the horizontally rotatableturret or carrier member 5, and a step rotation then imparted to the said carrier member to place vthe orifice with its d-isk-fblank positioned therein in alinement with the cutting means situated at the cutting station'A. Reciproeating motion is then imparted to the opposingco-acting cutting plunger for -the cutting of a central core piece from the blank andi 16 of the orifice or opening 15 of the turret or carrier member 5. The said carrier member with the positioned cut ring liner is then gildvanced by a step or intermittent rotation until the orifice containing thering liner is in longitudinal alinement with the feed mechanism for the can end. when the lowermost end 13 from a stack of ends contained within the holder 11 is fed onto the stationary table or platform and placed into axial alinement with the orifice 15 containing the cut ring liner. the flange of the end at such time being partly embraced by the wall of the cut out portion in the under face of the turret or carrier member leading to said orifice. The turret or carrier member with the properly positioned cut liner ring and can end is then advanced to the assembling station B to place the positioned cut ring liner and can end in vertical alinement with the assembling means. motion being imparted to means at such time to assemble the ring liner and the can end by moving the same relatively axially toward each other while the ring is within the orifice. There at'ter. the assembling means separate and the turret o1 carrier member moves the lined can end over the surface of the table or platform 2 toward the discharge outletthereof, where the same is discharged and conveyed toward asuitable place of deposit.

Having thus described the invention what is claimed as new and desired to be protected by Letters Patent is 1. The method of cutting and applying ring liners to flanged can ends. which consists in successively transporting disk blanks of lining material step by step in a substantially. horizontal plane; cutting ringliners from the'peripheral portions of the successive blanks at an interval between two of such steps; forcing the central parts'or wastes of said disks down through and from .the .ring liners; successively moving can ends, with their flanges which are to be lined projecting upward in a lower substantially horizontal plane and bringing them to rest in line beneath the said ring liners as they successively pause at a subsequent interval between two of such steps; and forcing down the successive ring liners along the interior walls of the flanges of their respective can ends at a subsequent interval be tween two of such steps.

2. The method of cutting and applying ring liners to flanged can ends. which consists in successively transporting disk blanks of lining material step by step in a substantially horizontal plane: cutting ring liners from the peripheral portions of the successiveblanks at an interval between two of such steps: forcing the central parts or wastes of said disks down through and from the ring liners: successively moving can ends, with their flanges which are to be lined projecting upward, in a lower substantially horizontal plane and bringing them to rest in line beneath the said ring liners as they successively pause at a subsequent interval between two of such steps; transporting both the ring liners and the can ends and maintaining their said relation the latter in ring liners to flanged can ends, whicl1.con-' .slsts 1n successively transporting dlsk blanks of lining material step by step in a substantlally horizontal plane; cutting ring liners from the peripheral portlons of the successive blanks at an interval between two of such steps; forcing the central parts or wastes of said disks down through and from the ring liners; successively moving can ends with their flanges which are to be lined projectingupward. in a lower substantially horizontal plane and bringing them to rest in line beneath the said ring liners as they successively pause at a subsequentinterval between two of such steps; transpbrting both the ring liners and the can ends hnd maintaining their said-relation the latter in line beneath the former. with the transporting medium interposed between themz and forcing down the successive ring liners through the transporting medium and along the interior wvalls of the flanges of their respective can ends at a subsequent interval between two of such steps.

l. The method of preparing the flanges of can ends to be subsequently attached to can bodies by means of an interiolded joint or seam to form a hermetic seal consisting in successively positioning cut can end flange liners in spaced relation; conveying the liners successively in said spaced relation to each other in the plane occupied by the liners; and at the same time maintaining control of and the shape of said liners c1r-' cularly successively alining the said out liners with positioned can ends; and unit ng the liners and can ends by movement at substantially right angles to the plane of con-' veying.
