DIVI8ION A.

To all whom it may concern:

Be it known that I, CHARLES \V. GRAHAM, a citizen of the United States, residing in Allenda-lc, in the county of Bergen and State of New Jersey, have invented a new and useful Improvement in Can-End and Gasket Assembling Machines, of which the following is a specification.

This invention relates to an improved mechanism for applying gaskets or ring liners of paper or other fibrous material to the seaming flanges of can ends, such as are used in the manufacture of what are com-' monly termed sanitary or double seamed cans.

()ne object of the invention is to provide a mechanism of the type above indicated, which will cut an annular gasket from a web of paper or other fibrous material and apply or deposit the same on the flange of a can end in such a manner that the gasket is never dependent upon the force of gravity during the assembling operation.

Another object of the lnvention is to provide a mechanism which will perforate and cut an annular gasket from a web of gasket material at one stroke and during a single operation.

Another object of the invention is to provide a mechanism in which the elements used for perforating and cutting out the annular gasket also serve to positively position the gasket on the cam end flange.

A still further object of the invention is to provide a ll'leCllil-IllSlll for applying gaskets to can ends, which comprises gangs of mechanisms so arranged that a plurality of gaskets and can ends are treated simultaneously.

I am aware that hitherto attempts have been made to provide machines which will cut annular gaskets from paper or other fibrous material and deposit the same on the seaming flange of can end-s. But such machines, so far as I am aware, have proved more or less defective, in that means have not been provided'for at all times keeping the light. flexible. cut gasket under positive control while assembling the same with the canend, thegasket at: some time or other during the assembling operation generally being dependent upon the influence of gravity for its movements from one part of the mechanism to another.

' In my improvements, I have provided means which overcome all the objections hitherto found in prior machines-for applylng paper gaskets to can ends, and in which the gasket is at all times positively and mechanically controlled and moved. Said means are fully disclosed in the drawings, and in said drawings,

Figure l is a front elevation of a machine embodying my improvements, showing the gang punches in position to assemble the gaskets within the circumferential grooves of the can ends, the web feeding mechanism being omitted to more clearly show the other parts; L Fig. 2 is a partial vertical section, upon a somewhat larger scale than Fig. 1, and taken substantially on the line 2-2 thereof, the

web' feeding mechanism being shown in end nism being omitted in Fig. 4, and parts being broken away in Fig. 5, to more clearly disclose the construction;

Fig. 6 comprises a plurality of vertical, sectional views, of'the compound punch and die mechanism which perforate, cut and assemble the gaskets on the can ends. said views representing four different relative positions of the punch and die;

Fig. 7 is a longitudinal, vertical, sectional view of the multiple can end carrier, detached, and taken substantially on the line- 7-7 of Fig. 5; i

Fig. 8 is a detail, sectional view, taken substantially on the line 88 of Fig. 2, illustrating a portion of the web feeding mechanism; and

Fig. 9 is a diagrammatic view, illustratbyfilheir operating cams.-

ing two complete cycles of movements of the combined punches and cutters, as controlled drawings, the machine as shown comprises a base. plate 10, havin upri ht standards 11 and a horizontal b 12. xtending upwardly from the bed 12 on opposite sides thereof are a pair of uprights 13, the same being provided at their upper ends -with suitable ournal boxes 14, in which is mounted. a power shaft 15, driven. from any suitable source (not shown) as b means of a pulle 16. Fixed on said sha t 15 are a pair 9 cams 17, more particularly hereinafter described, which are adapted to reciprocate a cross head 18, mounted in guides 19 secured on the uprights 13. Secured to the end of the shaft 15 is a bevel gear 20,

vwhich is adapted to operate a main driving shaft 21, extending longitudinally of the machine, through the intermediary of bevel gear 22, vertical shaft 23 and bevel gears 24 and 25. Mounted on the bed 12 is a bolster plate 26 which supports a plurality of compound dies 27, with which cofiperate a corresponding number of compound punches 28 mounted in the cross head 18, the'number of said compound dies and compound unches shown in the drawing being four,

ut it will be understood that moreor less may be employed, if desired. Reciprocally mounted on the bed 12 in ways 29 is a multiple can end carrier 30, operated from a cam 31 on the shaft 21, througha forked rod 32, having a roller engaging in the groove of the cam 31, said rod 32 having a yieldable connection 33 with a second rod 34 pivotally connected to a lever arm 35, which in turn 'has pivoted thereto at its outer end a link 36, pivoted to the rear side of the carrier 30.

As more clearly shown in Fig. 2, the bolster plate 26 is provided with a threaded, adjustable stop 37 b which the carrier is brought to rest at t e end of its forward stroke, to thereby roperly position the can ends carried by it in allnement with the punches and dies, as hereinafter described, any excess movement of the carrier wh ch would be imparted to it by the cam 31 bem taken up by the yieldable connection 3 The carrier 30 is provided with a plurality of circular pockets 38, the number of said.

pockets corresponding to the number of the dies and punches, each pocket being of a diameter large enough to permit can ends 39 to pass therethrough, and each being provided with a stationary segmental le ge 40 and a retractable segmental ledge 41, formed on an arcuate mem r 42 pivotally connected to and operated by a be 1 crank 43, all of the bell cranks 43 being in turn pivotally connected to an operating bar 44, longitudinally slidable on the carrier and held in ablysu ported rollers 48 and adapted to be driven y means of a sprocket gear 49, secured to the end of one of the rollers, said sprocket gear 49 being driven-by means of a sprocket chain 50, running over a sprock t gear 51, secured to the shaft 21. The cam 31'is so designed that the carrier 30 is given a dwell or period of rest at each end of its reciprocation, and while in its rearmost position, a plurality of can ends are adapted to be fed from stacks and dropped into the [POOkGlLS 38 simultaneously, by means of a plurality of feeding mechanisms 52 mounted on a bridge 53, extending over-the carrier 30, said feeding mechanisms 52 each including a spiral gear 54 operated by means of corresponding spiral ars 55, mounted on'a longitudinally extending shaft 56, driven b means of a spiral gear 57 on'the end thereo' and which meshes with a spiral gear '58 secured to the vertical shaft 23'. A detailed description of the fading mechanisms 52, which are all similar, is omitted, since the same are fully disclosed in my Patent No. 1,158,045, granted October 26, 1915.

By referring to Fig. 6, it will be seenthat each compound die comprises a stationary outer member 59, having a guideway 60 therein on its up er face, for a web 61 of paper or other suitable fibrous, gasket formin material. Slidably mounted in a circu ar recess 62, formed in the member 59, is an annular female die 63, normally held in its uppermost position by a spring 64, the upper face of the die 63 being normally flush with the bottom of the guide 60, so that the web 61 lies flat thereon. Secured to the fenlilale die 63, and movable therewith, is a disc ar disks 66, punched from 'the web of gasket, material, are adapted to pass and be-"discharged from the machine.

Each punch 28, cooperatlng with a die 27,

means of a spring 70. Theannular gasket a or rin liner is cut from the web of gasket materlal 61 as follows: As the com und punch descends, the perforating mem r 68 tube 65, down which the circular III thereof, being in advance, will first punch out a circular disk 66 from the web by passing into the annular female die 63, as shown in view I) of Fig. 6, and as the descent of the compound punch continues, the face 69 of the annular cutting member 67 will engage the uncut portion of the web and press the female die .63 down with it against the action of the spring 64, thereby cutting an annular gasket 164 from the web, as shown in view 0, Fi 6. As the com ound punch is started on its u -stroke, the fiamale die 63 will move upwar ly therewith, thus serving to positive] retain the cut ring against the face 69 of t e annular cutting member until the female die 63 reaches its uppermost normal position; Upon the contlnued upward movement of the compound punch, the ring liner will be carried thereby, since the same Will be held by frictional contact to the out- .side of the perforating punch 68, as shown in view (1, Fig. 6.

Although not essential to the successful operation of my mechanism, the annular cutting member 67 of each punch may be provided with a chamber 71, having a plurality of passageways 72 leading therefrom to the cutting face 69 and the chamber connected by means of short pipes 7 3 to a chamber 74 mounted on the cross head 18, said chamber 74 being common to all of the punches and being connected to a combined vacuum and blast pump (not shown), so'

regulated that a vacuum is created in the chambers of the punches during the upstroke, and an increased pressure or blast caused at the end of the short down stroke of the unch when the gasket is being assemblelf with the can end, as hereinafter described.

The webs of aper or other fibrous material are supplied from rolls 75, mounted on a transversely extending shaft 76, there being a separate roll of material for each set of punches and dies. The web passes through a slot 7 7 in the bed 12 and bolster plate 26, over a roller 78, along the guide 60,

and is pulled or fed intermittentl by thefollowing arranged mechanism. he scrap of the web asses between two rollers 7 9,79, longitudina ly arranged on the front of the machine and common to all the webs being fed, said rolls being mounted in suitable journal boxes, one of which is preferably adjustably and yieldably mounted, as shown in Fig. 2. The ends of the shafts supporting the rollers 79 are provided with meshing gears 80, the lower one of which is provided with a ratchet face 81 (see Fig. 8) androtated step by step bymeans of a spring pressed pawl 82 located in a gear 83 rotatably mounted on the extended shaft of the lower roller 79, and oscillated by means of a rack bar 84, which receives a reciprocating movement by means of a bell crank lever 85 from a cam 86 mounted on theoperating shaft 21, the cam 86 being so timed that the webs of paper will be pulled through the dies while the punches are in elevated position. As shown in Fig. 6, each die is provided with a plate 87, provided with a. suitable opening 88, throu h which is adapted to. pass the compoun preventing the lifting up of the scrap of theweb of gasket material during the upstroke of the punch and serving as a stripper.

The operation of the machine during a complete cycle is as follows: Starting with the parts in the position as shown in Fig. 3, in which position the gasket is just being deposited in a can end 39, a continued rotation of the cams 17 in the direction indicated by the arrow m-through the angle included between the radial'lines 1' and s will lift the cross head 18, carrying the punches 28 therewith, a distance corresponding to that between. the points R and S on the diagrammatic outline of the cam shown in Fig. 9. Immediately after the punches are started on this part of their short upstroke, the carrier 30 will be retracted, during which movement the assembled can ends and gasket", will be released, as hereinbefore described, and the carrier finally brought. to a position where the can end pockets 38 are in alinement with the feeding devices 52, and the carrier will then have a period of rest long enough to permit of the deposition of the can ends in the pocket. As the cams 17 continue to rotate through the angle between the radial lines 8 and-t (Fig. 3,) the cross head 18 will descend an amount corre- 'sponding to the distance indicated between the points S and T on the diagrammatic outline, Fig. 9. During this downstroke, the perforating and cutting operations will take place in the manner described in con-.

punch, said plate nection with the detailed description of the" compound punches and compound dies. Upon the continued rotation of the cams 17 through the angle between the radial lines tand u, the cross head will be raised as indicated by the line between the points T and U; in Fig. 9, and'during this upward movement, after the punches have been raised above the level of the top of the carrier 30, the latter will begin to move forward, carrying with it the can ends or closures which have been de osited in the pockets 38. During this upward movement of the cross head and punches, the paper Web 61 will be fed through the dies 27 to thereby position a new portion of the web in position for another gasket to be cut therefrom. Upon the cams 17 continuing their rotation .an amount corresponding to the angle between the rastroke and the gaskets carried by the punches will be de sited in the can ends on the carrier, which will have been brought to rest prior to the punches reaching their lowermost point in the short down stroke. This movement of the cross head and punches is denoted in Fig. 9 by the line between the points Uwand R. As will be understood, the foregoing cycle of operations will be repeated for each complete rotation of the cams 17. r

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore describedbeing merely a preferred embodiment thereof.
