Specification of Letters Patent.

HE FLANGES OF CAN I Patented Jan. 13, 1920.

Application filed January 29, 1916. Serial no. 75,038.

the Flanges of Can Ends, of which the following is a specification.

The present invention relates to a machine for cutting ring liners from a continuous web or blank, and applying the same to the flanges of positioned can ends,

and has for its object'the provision of a machine for this purpose, simple of construction, and which necessitates the use of relatively few moving parts, particularly those to which reciprocating motion must be imparted.

To this end the invention comprises broadly associated instrumentalities for cutting a disk blank from a continuous web, for cutting a ring liner from said blank, and for applying said ring liner to the flange of a can end in axial alinement therewith, interworking in timed relation with devices for holding and carrying the blank and ing liner, and means for positioning a can end in proper relation thereto for the reception of said liner.

In order to more fully comprehend the invention, a preferred embodiment of which is hereinafter described, referenceshould be had to the accompanying sheets of drawings wherein Figure 1 is a front elevation of the complete machine.

F i 2 is a vertical section taken. on the line of Fig. 1,.and viewed in the direction of the arrows.

Fig. 3 is a horizontal section taken on the line y of Fig. 1, and viewed in the direction of the arrows.

Fig. 4.- is a detailed vertical section, enlarged, taken on the line 88 of Fig. 3, and viewed in the direction of the arrows.

Fig. 5 is a detailed vertical section, enlarged, taken on line 5 2? of Fig. 3, and viewed in thedirection of the arrows.

Fig. 6 is an enlarged detailed verticai section taken on the line a-a of Fig. 3, and viewed in the direction of the arrows:

Fig. 7 is an enlarged detailed vertical section taken on the line w w of Fig. 3, and viewed in the direction of the arrows.

In the drawings, the reference numerals 1 designate the spaced upright side members of a suitably constructed supporting frame, which side members are united together and held in spaced relation by a cross member 2 at their lower portions, a similar cross memher 3 at their upper portions, and between said cross members by vertically disposed wibs 4 and 5, and a horizontally disposed ta ie 6.

Power for operating the moving parts of.

the machine is applied to a horizontal shaft '7, rotatably mounted in the upper portion of the frame, by means of a belt pulley 8 fixed thereon. It is to be understood, however, that any suitable form of driving means may be employed. The horizontal drive shaft 7 transmits its rotary motion by means of a vertical shaft 9, Fig. 1 of the drawings, to a second horizontal shaft 10 suitably journaled in the lower portion of the frame. latod that they rotate in unison.

The upper shaft 7 carries a crank 11, Figs. 1 and 2 of the drawings, which imparts vertical reciprocating motion, through a connecting rod 12, to a head 13, slidably mounted upon the upper web 5 of the frame, and retained in position by suitable guides 14. This head 13 has an enlarged lower portion 15, which carries a series of depending dies, shown at 16, 17 and 18 respectively, in Fig. 1 of the drawings, and which will be .more fully described hereinafter. In a similar manner the lower shaft 10 carries a crank 19, which imparts vertical reciprocating motion, through a connecting rod 20, to a head 21. slidably mounted in suitable guides 22 upon the lower web t of the frame. Said head 21 carries upon its upper end a dle ring 23, Figs. 2 and 5 of the drawings, adapted to coact with the die 17 through an opening 6 in the table 6, for a purpose to be later set forth.

A horizontally disposed turret 24 is rotatably mounted above the table 6 and beneath the upperreoiprocating head 13. Said turret is formed with a plurality of vertical openings therein, there being four of said Said shafts 7 and 10 are so reby structural considerations.

' 28, adapted to mesh with a similar gear 29 horiz the. turret 2% i ,7 .thus carrying the dish 43 from the position 'ri to the position B,-

fixed upon the lower end of a second vertical shaft 30. This latter shaft 30 is rotated intermittently from the lower horizontal shaft 10, by means of coacting mutilated worm gears 31 and 32, in such relation that for every complete revolution of the hori zontal shafts and 10, the turret 2% is turned to bring one of the openings therein into axial alinement with the die 16, that is, in the particular machine herein illustrated,

one quarter of a revolution.

The web 33 of paper or other material from which the mug liners are to be. cut is shown in Figs. 3 and t of the drawings, as

carried upon a spool or roll 34, and led in a ntal direction across the machine 11nniedrately above a plate which is secured at 36, to the table 6, extending over the turand provided with an opening 37 in which is mounted a stationar die rin 38 of size suitable to react with the reciprocating die 16, as shown in Fig. lof the draw ings. The web 33 is then passed between a feed roller 39 and an idler roller d0, the former being intermittently rotated by the turret shaft 27 through the agency of the short geared shafts L1 and L2, to intermittently feed said web through the machine at the proper rate. 4

It will be by reference to Fig. f of the drawings, that the die 16', being forced down into the coacting stationary die ring 33, cuts a circular disk from the inter-- ml) 33, and deposits said disk on the g h s disk cutting operation, said s ationary. immediately following the rr sing of the die 16, however,

s moved one step fmw/ard,

V rig. 3 of the drawlngs, in which latter position it is in axial alinement with the upper reciprocating die 1'? and the coacting lower reciprocating die ring-23,Figs. 2 and 5 of the drawings.

The upper die 17 is encircled by a stripper ring -14, which has a limited range of vertical movement thereupon, and which is normally held at the lowermost limit of said movement by springs 45. The upper die 17 and the lower die ring 23 are moved simultaneously in opposite directions by their re- 3 spectlve; operating mechanisms hereinbefore flange 26 within the opening 25 in is linden-stood, of course,

die and die ring 17 and 23 are then sep-.

arated, and the stripper ring removes the cut ring liner 16 from the die 17, and leaves the same deposited on the shoulder 26 of the opening of the turret 24E. Said turret 2-fl is then advanced another step, to bring the opening 25 with the cut ring liner a6 therein to the position C in Fig. 3 of the drawings, where it is in vertical alinement with the third upper reciprocating die 18.

Fixed upon the upper end of the vertical intermittently rotated shaft 30, above the table 6 and underlying a portion of the turret 2a, is a second turret 18,Figs. 1, 3, 6

and 7 of the drawings, formed with circular lower continuously rotating shaft 10, and a lever Said feed slide 53 moves the lowermost freed can end from the holder through one of the radially disposed grooves or slots 56 in the under side of the turret 13 until said can end lies within one of. the openings +29, at the position D in Fig. 3 ,of the drawings.

A circumferential groove 57 is also formed in the under side of the turret e8, which lies over a circular guide rail 58, secured to the table 6, and formed with air opening 59 adjacent the holder 51, through which theends are pushed by the, feed slide 53.

Thus it will be seen that a can end 50, seated within one of the circular openings 49 in the turret 48', will be carried around over the surface of the table 6 bythe movement of said turret and will he prevented from escaping through the slot 56 by the guide rail 58.

In this manner a can end 50 is carried to the position C, Fig. 3 of the drawings, where it rests upon the table 6 below and in vertical alinement with the ring liner 4E6 which is supported within the opening 25 in the turret 24:. During a period of rest of both turrets, the upper reciprocating head 13 moved downward to bring the assembling (lie 18 down through the openings 25 and 49 in theturrets 24 and 48 respectively,

and to force the ring liner 46 from its seat 26 in the opening 'down onto the flange of the alined can end 50, as shown in Fig. 6 of the drawings. 7

At the next step in the rotation of the turret 48, the can end 50, with its assembled ring liner l6, is carried to the position E, Fig. 3 of the drawings, at which point there is an opening in the table-6, through which said lined can end drops, and from which it is carried as by a chute 61, Figs. 3 and 7 of the drawings, to a suitable place of deposit not illustrated.

It is to be noted that in the preferred form of the constructed apparatus, the

I blank cutting die 16, the ring cutting die 17 every stroke of said head, a blank is cut from the web at A in Fig. 3 of the drawings, a ring liner is cut from a blankat B, a ring liner is applied to a can end at C, an unlined I can end is fed from the holder at D, and a lined end is discharged from the machine at E. The die ring 23, carried by the lower reciprocating head 21, coeperates only with the ring cutting die 17 at the position B.

The invention has hereinbeen described and illustrated in its preferred form. I do not wish to limittmyself thereto, however, for the reason that many changes may be made in the machine as ilustrated without departing in any manner from the spirit of the invention, and it is therefore my wish to be understood. claiming'the invention as broadly as the art will permit.
