To all whom it may concern:

Beit known that I, JAMES A. GRAY, a citizen of the United States, residing in the city and county of San Francisco and State of California, haie invented certain new and useful Improvements in Apparatus for Cutting and Applying Ring-Liners to Can- Covers, of which the following is a specification.

The present invention relates to an improved m'achine for cutting ring liners from a traveling web of paper, depositing the same Within a seat of a rotary carrier, supplying a can cover within said seat of the carrier in advance of thering liner, and forcing the placed ring liner within or onto the flange of the can cover, the various steps in the operation of the machine being auto matically and successively carried out through the action of a series of inter-connected 'instrumentalities so arranged relative to each other and timed as to their action of movement as to come into play at predetermined moments; the object of the invention being theproduction of an automatically operated machine for the cutting and placing of the ring liners relative to the can cover which shall be simple of c0nstruction, positive in its action, durable and composed of comparatively few working parts.

To comprehend the invention, reference should be 'had to the accompanying sheets of drawings, wherein Figure'l is a plan view of the improved machine disclosing the relative position of the cutting punch for severing the ring liners from the traveling web, the mechanism for imparting reciprocating motion thereto, the barrel or magazine for receiving the central disk severed from the traveling web in the cutting of the ring liners. the mechanism for delivering the can'covers to the rotary carrier (not shown) the disposition of the web of paper from which the ring liners are cut, the means for feeding the web acrossthe front of the cutting punch, and the feed mechanism for the can covers. Fig. 2 is a longitudinal sectional view taken on line :P:n Fig. 1 of the drawings, viewed in the direction of the arrow 0, illustrating more particularlv the drive mechanism for imparting reciprocating movement to the cutting punch and transmitting an intermittent or step rotation to the carrier for the can covers and ring liners.

and the means for actuating the reciprocal?- ing plungers for forcing the ring liner ontothe circumferential flange of the can covera. Fig. 3 is-a vertical sectional view taken on line y-y Fig. 2 of the drawings, the barrel or magazine for the central disk cut from the traveling web being removed and the Web of paper being partly broken away, said view disclosing the rotatable carrier for the .can covers and ring liners, the means for delivering the out ring liners to the seats of the said carrier, the feed mechanism for the can covers, the position of the traveling web, the feed means for advancing the web through the machine in advance of the cutting punch, and the discharge runway for the lined can covers. Fig. 4 is a detail view of one of the cut ring liners. Fig. 5 is a cross sectional view of one of the'can covers, within the circumferential seat of which formed by the inturned edge of the flange of the can cover is forced the ring liner. I In the drawings, the numeral 1 is used to designatany suitable form of a supporting frame capable of sustaining the various working parts of the apparatus, and 2 a bed mounted thereon and within guide ways 3 of which works the reciprocating slide 4 carrying at its inner end a detachable punch 5, and a die ring 5, Figs. 1 and 2 of the drawings. The said slide 4 is actuated by a cam 6 acting against rollers 7 and 7 mounted within a cross head 8 secured to and carried by the outer end of the slide r, the said actuating cam 6 being mounted on a crossshaft 8'- working in bearing boxes 9.

Between the punch 5 and the die ring 5' screwed to the slide 4 there is interposed an ejector ring 5*, which is permitted slight movement under pressure of the punch 5.

From the said ejector. ring projects a series of bolts 0 which extend through bores in a circular shoulder (Z of the reciprocating slide 4 and act against a collar c slidably mounted on said slide and which is engaged by a finger 7" fixed to and upwardly projecting. from the frame of the machine on the return stroke of the slide 4 to force the ejector ring a slight distance beyond the die ring 5 to force the cut ring liner from off the punch.

The shaft is driven in any suitable manner, pret'trably by means of a power belt working over a belt pulley 9' secured to one end thereof, the said shaft at its opposite end carrying a gear wheel 10 which meshes with a gear 10 for transmitting rotation to a cross shaft 11 situated below the shaft 8 for imparting motion to the hereinafter described actuating means for giving a step rotation to the carrier'containing the can covers and liner rings to be applied thereto.

In front of the punch 5 and held a slight distance therefrom is situateda die ring 12, the same being loosely held to the innerend of a cylindrical magazine 12 and normally held outwardly pressed by the springs a, the magazine being attached to the frame of the machine, and in line with the punch 5 to receive the waste material or central disk cut from the web out of which the liner rings are formed, the die ring 12 being held to the magazine 12 by the securing collar 6 united in any suitable manner to the said magazine.

' The paper web 13 out of which the ring liners are cut is fed transversely through the machine between the punch 5 and the maga- Zine 12 by means of the vertically disposed guide feed rollers 13 and 14, the said web unwinding from a spool 1% loosely mounted on a short vertical stud 15 situated at one side of the bed 2 of the frame 1Figs. 1 and 3 of the drawings. The guide roller 13 a positively driven one, while the roller 14 is loosely mounted on a stud 1 upwardly projecting from a slide rod 14 and is frictionally driven, and the said roller 13 is driven by means of a bevel pinion 15. secured to the lower end thereof meshing with a bevel pinion 16 on a longitudinally disposed shaft 16 working in bearing 17 at one side of the machine. This shaft .16 at its outer end carries a bevel pinion 17 which is engaged and driven by a bevel pinion 18 on the rotating cross shaft 11, having rotation imparted thereto from the drive shaft 8 through the described gear connections.

The web 13 is advanced through the machine only when frict ionally engaged by the guide and feed rollers 13 and 14, but the travel of the web is an intermittent one due to the fact that the roller 14: is only in engagement therewith at pre-determined moments, being normally held out of engagement or away from the surface of the web by the tension of the spring 13 connected to and acting against the slide rod 1%. At its outer end the said slide rod carries a roll 13 loosely mounted on a laterally projecting stud 13 and said roll is intermittently engaged by a cam 15 on the drive shaft 8 acting thereagainst. When the cam 15* acts against the roll l3 the slide rod 14 is forced forwardly, carrying therewith the guide feed roller 14- for frictional engagement with the web 13. which is then firmly tudin-allydisposed shaft 19, carrying at its inner end a bevel pinion 20 meshing with a similar pinion 20 on the lower end of a short vertical shaft 21. This shaft at its upper end is provided with a gear 22, which meshes with and imparts rotation to a gear ring 22 encircling the lower end portion of a can head holder 23, and said ring in turn meshing with a gear 23 imparts rota tion to a short vertically disposed shaft 24- carrying a screw disk 24, a companion screw disk 25 being secured to the short vertical shaft 21 to which is attached the gear 22 and the bevel pinion 20. The said screw disks 24: and 25 are located below the'bottom of the can head holder-28 and serve as a screw feed means for delivering the horizontally disposed can covers or heads 26 from within the holder 23 into a downwardly inclined chute or runway 26, the said heads or covers as they leave the screw feed bearing-against a bridge piece or plate 27 located within the upper portion of the chute or runway 26 and are thrown from a horizontal into a vertical position-Fig. 3 of the drawings...

Within the frame of the machine and on a-lbngitudinal shaft 28 working in bearings 28 thereof is situated a vertically disposed rotatable carrier disk 29, whose movement in the direction of its rotation is designated by arrow a on Fig. 8 of the drawing, and the said carrier disk is provided with a plurality of transversely oircumferentially disposed openings or seats 30, within each of which work a pair of opposing normally spaced hollow reciprocating 'plungers 31 .seats 30 is intersectedby a segmental pe ripheral opening 34, and a similar opening 3 1 through which the ring liners35 and the can covers' 26 respectively are deposited vertically within the seats 30 between the opposing faces of the plungers 3l and 3 2, 1

the can htfldS 01" covers 26 being delivered cover and ring liner stand in vertical position between the plungers'31 and 32 and in front of the spring held chuck 31 of the .plu'nger 31, with the ring liner in advance of and in alinement with the flange 26 of the cover 26, so that on the plunger-s being brought together the said ring liner 35 will be forced onto the circumferential flange of the can head or cover 26, during which seating of the ring liner the chuck 31 is gradually moved within the plunger 31.

By reason of the disposition of the cam grooves 33 of the fixed disks 34 the plungers are held in such inwardly pressed position until by the rotary movement of the carrier disk the rolls 33 are carried within the outwardly extended portion of vthe cam grooves, by which time-the opening 34' of the seats 30 will be in line with the discharge runway 36 and the plungers or pistons 31 and 32 moved away from each other or separated. when tension of'the springs 36 coming into play forces outwardly the chuck 31 to unseat the can head or cover 26 with its applied liner ring, and place the same immediately over the opening 3i through which the same escapes by gravity into the discharge runway or chute 36 for delivery to a suitable place of deposit.

An intermittent or step rotation is 1mparted to the shaft 28 and the carrier disk 29 secured thereon by means of the mutilated worm gear 37 secured to the outer end of the shaft '28, which worm gear is intermittently engaged and given a part rotation by the worm section 37' of a disk 38, secured to the drive shaft 11 meshing therewith atgiven intervals. The rotary motion of the driveshaft is thus transmitted to the shaft 28 and the carrier disk 29 for imparting a step or intermittent rotation thereto.

During the forward stroke of theslide 4 thepunch 5 and die ring acting against the web 13 forces the same firmly onto the 1agar.ine 12', the punch 5 acting first to cut the central disk from the web and the die ring 5 associated with the punch 5 by the continued movement of th slide 4 ('(i acting with the die ring 1? cutting tho ring liner from the web 13. the removed cen tral disk or body of the ring moving in o the magazine 19'. The liner ring adher s to the die ring 5 until on the outward stroke of the slide 4 and punch 5, the collar 6 engages with the bracket 7', forcing the ejector ring 5 beyond the face of the die ring 5" and punch 5 to release the cut liner ring 35, which escapes into and through the guide-way 38 and is deposited into one of the seats 30 of the carrier disk through the opening 34' communicating therewith. On the outward or return stroke of the unching mechanism, the feed devices for t e web 13 advance the same to place or position an uncut portion thereof in advance of the punch mechanism, the saidoweb remaining at rest during the cutting stroke of' the' punching Inechanism,.which intermittent or step feed movement of the web-13 is controlled by the before 'lescribed interconnected devices.

The working. stroke of the punching mechanism. the movement of the intermittent traveling web, the rotation of the carrier disk, and the feed mechanism for the can heads or covers are so controlled, regulated and timed with respect to eaolrother that the various described actions successively come into play at predetermined moments, so that each part performs its desired work at the proper moment with respect to the other working parts of the apparatus, thereby constituting an automatic machine for cutting liner rings, assembling can heads or covers and the liner rings, forcing the liner rings onto the flange of the can heads or covers, and discharging the can heads or covers with the ring liners applied thereto.

I am aware that various changes may be made in the working parts and the details of construction herein shown and described without causing a departure from the spirit of the invention, and I do not wish to be understood as so restricting, limiting or confining the invention, but on the contrary desire to cover the invention broadly irrespcctive'of the details of constrution of the working parts of the apparatus for carrying the same out; although the arrangement and construction of the working parts shown and described is preferred.
