Specification of Letters Patent.

Application filed September a, 1916. Serial no. 119,065.

To all whom it may concern: Be it known that 1, JAMES A. GRAY, a citizen of the United States, residing at the city and county ofSan Francisco and State of California, have invented certain newtmd useful Improvements in Apparatus for.

Forming and Flanging Can-Bodies, of which the following is a spec fication.

Thepresent invention relates to can makof food. products or othermaterial, are frequently flattened by compressing opposite sides, in order that they may occupy less space during shipment and storage. It is necessary, therefore,-to restore these flattened can bodies to their original shape before applying the first end or bottom thereto. The object, of the present invention is to provide a machine which may be used by a packer who has receivedand stored his sup:

, ply of cans in flattened form, for reforming the machine, certain said cans and forming the necessary flanges on the ends thereof for having appliedther'eto flanged ends.

In order to comprehend the invention,

reference should be-had to the accompanying sheets of drawings, where n:

Figure 1 is aside elevation of the com-. plete machine.

Fig. 2 is a sectional plan view looking in the direction of Fig. 1.

Fig. 3 is a of the arrows on,tl1e line 2.2

part sectional end elevation of parts being omitted for the sake of clearness.

Fig. 4 is a vertical section tlirough "thefeed mechanism, taken onrline ie-4 of Fig. 2

and viewed in thedirection of the arrows;

Fig. 5 is a longitudinal sectional detail taken on the line 5-45 of Fig. 3 and viewed in the direction of the arrows, showing the flanging mechanism.

. In the drawings the reference numeral 1 designates any suitably constructed base or bed-plate, which is preferablysupported upon legs 2, as illustrated in Fig. 1 of the drawings particularly. 1 v

Mounted upon the bed-plate 1 is' a superstructure 3, in which is journaleda horizontal transverse drive shaft 4, Figs. 1 and 2 of the drawings. This shaft 4 constitutes the main driving means for the entire machine, and is shown'as carrying a belt-pulley '0 at one end, by means of which said shaft may be driven.

A mutilated worm 6, Fig. 2 of the drawings, fixed upon the drive shaft 4:, and meshing with a Worm-wheel I mounted upon ashaft 8,-disposed at right anglesto the driveshaft 4, imparts an intermittent rofary movement to said shaft 8. The shaft 8 is gournaled in a superstructure 9,Wlll(3l1 is supported by the previously mentioned superstructure 3. A turret 10, in the present case mounted in a plane for vertical rota- Patented Sept. 2, 1919.

tion, is secured upon oneend of the shaft 8,

shown in the drawings as comprising a screw y 13 secured to the free end of each stud 11.'

Another horizontal-shaft MfFigs. '1, 2 and 3 of the drawings, parallel to theshaft 8, and below and to one side thereof, is journaled in brackets 17 and 18 mounted upon the bed plate 1, and is continuously driven by the, drive-shaft 4 through suitable bevel gears 15 and 16. Ayoke 19, Figs. 1 and 3 of the drawings, is pivoted atone end concentric with the shaft ldand in its outer end carries ashortrotatablymounted shaft 21, said shaft: 21' being driven by the shaft 14 through suitable spur gears22 and 23, and carrying an ironing or reforming roller 20,

positioned parallelto and adapted for contact With the cylindrical portions of the mandrels 12, when said mandrels are successively brought into. position by the intermittent ro tation of the turret 10. Contact between the roller 20 and the positioned mandrel 12 is preferably secured by means of a plate 24, Figs. 3 and 5 of the drawings, slidably mounted. upon studs 25 hired to the under sideof the bedlate 2, said plate 24 being ressed upward y by springs 26, and

the bed-plate 1 by means of two. spaced vertically disposed bracket members 28, Figs. 1,

2 and- 3 of" the drawings, WhlOh support, by

means of angle brackets 29, Fig. 1, an inner pair of spaced vertical plates 30, Figs, 1, 2

and 4, having angle members 31'fixed to their edges, said plates 30 and angle mem- .;bers 31 forming a vertical magazine for the reception of a stack of flattened can bodies 32. Immediately beneath the magazine thus formed is a horizontal guide plate 34, Figs.

1, 2, 3 and 4 of the drawings, in the guide ways 36 of which iscarried a sliding member 35. Horlzontal reciprocating motion 1 may be imparted to the slide 35 by any is fixed two forwardly extending convenient means the same comprising, in the present instance, 2. lug 37, Figs. 1 and 4 of the drawings, on the under side of said slide 35, a lever 38 connected to said lug 37 by means of a link 39, said lever 38 being fulcrumed at 40 to a bracket 40 extending fromone of the legs 2 of the machine, and

being connected by a pitman rod 41 to an eccentric strap'42 WhICh surrounds an ec'- centric 43 fixed upon the drive shaft 4.

The slide35 carries an upwardly extending lug44, Fig. 4 of the drawings, to which fingers 45 adapted to engage the lowermost can body 33 of the stack of can bodies 32 contamed within the magazine 30* and to push said lowermost can body out of said magaz ne and on to spaced guide members 46 ad acent thereto, each of said guide members 46 being carried by a pair of swinging spreader arms 47.- Said swinging spreader arms 47,,Figs. 1, 2 and 3 of thedrawings are mounted in pairs upon each side of the magazine supporting brackets 28, and have inwardly projecting lower ends 48 formedwith notches 49, adapted to engage the can body 33 when dropped, as hereinafter described, from its position upon the gu de members 46, and by laterally compressing said can body, to spread or expand it preliminarily. Said pairs of arms 47 are mounted upon and 51, the shaft 51 being extended, as

shown in Fig. 1 of the drawings, through a journal bracket 52, and carrying on its end a lever-arm 53, Figs. 1 and 3 of the drawings, said lever-arm being connected by a vertically disposed. pitman rod-54 with a yoke 55 embracing the drive-shaft 4, and carryin a cam-following roller 56, adapted to lie within and follow the groove 57 of a cam member 58, secured upon the driveshaft. Oscillatory motion is thus imparted to the shaft 51, and is transmitted. to the shaft 50by means of a bar 59, connecting levers 60 and 61, extending in opposite dispaced horizontal shafts 5O tively. Thus the opposite pairs of swinging arms 47 are caused to swing in and out simultaneously and in opposite directions.

The outward movement of the swinging spreader-arms 47 causes a separation of the guide members46, thereby permitting the can-body 33 to drop into the notches 49 of said spreader arms. The subsequent inward movement of said arms compresses said can body laterally and thereby spreads the same by an amount sufiicient to permit the entrance thereinto of a pair of spaced spreader rods 62, Figs. 1, 2 and 4 of the drawings and a spreader liorn 63 positioned between said spreader rods 62, said rods and said horn being carried by, and projecting forwardly from, the lug 44 of the slide. member 35. .Saidslide also carries a pair of spaced forwardly extending fingers 64, positioned below and extending beyond the spreader horn 63, as shown in Figs. 3

and 4 of the drawings, for engaging the end of a partially opened can body 33 and forcing the same onto a mandrel 12 positioned in proper alinement therewith. n apertured guide-plate 65, against whichthe preliminary spread can body 33 abuts, retains said can body in position during the entrance there'into ,of the spreader rods 62 and the spreader horn 63.

Thus it will be seen,'by reference to Figs.

2, 3 and 4 of the drawings, that in the present case three complete strokes of the slide member 35 are required to transfer a flattened can body from the magazine 30 to a positioned mandrel 12. The first inward stroke of said slide removes the lowermost can body 33 from the magazine by means of the pusher fingers 45, and pushes the same upon the guide members 46 carried by the swinging arms 47, Figs. 1 .and 4 of the drawings. During the return movement of the slide 35 said swinging arms are separated and brought together as previouslv described, to permit said can body 33 to drop into the notches 49 and to be laterally compressed thereby, and preliminarily opened. 'The second inward stroke of the slide '35 causes the introduction into the preliminarily opened can body 33 of the spreader rods 62 and the spreader horn 63, thereby further. expanding and spreading said can body. At the same time the suctherein a Hanging been preliminarily opened by the swinging arms4e7, is further opened by the spreader. rods and spreader horn, and the third flattened can body is removed from the maga- Zine by the pusher fingers 4:5, and positioned upon the guide members 46.

The can-body 33', positioned upon'the mandrel 12 at the position A, Fig. 3 ofthe drawings, is then carried by the intermittent rotation of the turret 10 to the posi-. tion B, at which position it is not acted upon. The next movement of the said turret carries said can body .33 to the position C, whereit is ironed and restored to its cylindrical form by contact with the revolving ironing roller 20. The following movement of the turret 10 carries the reformed can body-to the position D, at which the 'flanging operation takes place. 7

This Hanging is accomplished by the following mechanism: The mandrel 12 is formed near its inner end, as shown in Figs.

2 and 5 of the drawings, with a portion 66 a of enlarged diameter, the diameter thereof bein that of the interior of the reformed can body. A shoulder 67, having formed oove 68, is formed upon the mandrel 12Qad]acent 'to and behind 1 said enlarged portion 66.. A reciprocating ing die 69, adapted to be introduced over the end of the mandrel 12, has at its free end an annular portion 7 0 of a diameter sufficient to enable it to enter the end of" the reformed can body 33. i A shoulder 71, having formed therein a fianginggroove 72, is formed upon said die 69 immediately back of the portion 70. Thus by forcing the die 69'over the end of the mandrel 12 and against the end ofthe can body 33" carried thereby, the ends of .dll

said can body are forced over the'enlarged portions 66 and 70 of the mandrel 12 and the die 69 respectively, and said ends of said can body 33' are flanged outwardly by the flanging grooves'68 and 72., Reciprocating motion is imparted to the die 69 by means of a sliding rod 73, by which said die is carried, said rod being suitably supported in a bracket 74, and having its outer end connected at 75, Figs. 1 and 2 of the drawings, with a lever 7 6, said lever being fulcrumed at 77, and carrying a roller 78 adapted to follow a groove cam 79 carried by the end of the rotating shaft 14:. It is to be under stood that the movement of the flanging die 69 is so timed with relation to the movement of the turret 10, that each can body is flanged at the position D, Fig. 3 of the drawings.

1 At the position Ethe reformed and flanged can body is ejected from the mandrel 12, into any suitable place of deposit not shown in the drawings, by an ejector finger 80, Figs. 1, 2 and 3 of the drawings, carried upon the end of a slidably mounted rod 81.

said rod passing through the hollow turret-Q.-

ang-

of the swinging-arms 47 and" is compressed 1ink82, Figs. 1 and 2, a lever 83, fulcrumed at 84, and having its lower end connected at 85, with rod 86, extending under the ma-' chine to the lever.38, and pivotally connectedtherewith at 87.

To enable the ejector finger 80 to pass behind the inner fianged end of the can body to engage the same for the purpose of eject ing it from the mandrel, said canbody must be initially moved upon said mandrel, to free the inner flanged end from the flanging groove 68. F or this purpose a stationary cam member 88, Figs. 1, 3, and 5 of the drawlngs, is provided, said cam member bebody is suflicient to free the inner end of said can body from the enlarged portion 66 of the'mandrel 12, so that said can body is loose upon saidmandrel, and can be easily engaged and removed by the ejector finger 86.

The operation of the .machine. may be briefly summarized as followst A supply of 9.5

flattened can bodies 32 is placedin the magazine 30 ,-.the lowermost can body 33 resting upon the pusher fingers 45'. Upon the withdrawal and subsequent return movement of the slide 35, said lowermost flattened can body 33 is removed from the bottom of the magazine 30 by said pusher fingers, and POSltlOIlBd upon the guide members 46. Said can body is then engaged by the notches 49 laterally thereby. The spreader rods 62 and the spreader horn 63Iare then introduced into saidv can body to further spread or open the same, after which, upon the nei'rt inward movementof the slide 35, the can I body is forced onto the positioned mandrel 12. Theintermit'tent rotation of the turret -10 carries the mandrel 12, with the partially reformed can body 33' thereon, to the position C of Fig. 3 of the drawings. ln this position the ironing roller 20, revolving in contact with the can body 33, restores the same to its original cylindrical form. The reformed can body is then. carried to the position D,..where endfianges are formed thereon by action 'of the Hanging die 6911s hereinbefore described. v

The next movement of the turret 10 carries the reformed and flanged canbody to the position E, where said can body is 're movgg from the mandrel by the ejector linger V The various interworking parts of .the machine are so timed-asto act successively upon can bodies positioned-upon each of the Alto mandrels 12, carriedby the turret 10. Thus as each of said mandrels 12 passes the position A, Fig. 3 of the drawings, a flattened can body is partially spread and pushed thereupon, and each can bodyis reformed at the'position C, flanged at the position D,

and ejected at the position E, as its mandrel is successively carried to said positions.

The invention has hereinbefore been described and' is herewith illustrated in its preferred form. It is to be understood however, that variations may be made in the construction and arrangement of the working parts of the machine without altering,
