ENn-FLANGING MEGHANISM son CAN-BODIES.

'To all whom 'it may concern: is Be it known that I, HENRY G. BLACK, a citizen of the United States, residing at the city and county of San Francisco, State of California, have invented certain new and useful Improvements in End-Flanging Mechanism for Gan-Bodies; and 1. do hereby declare the following to lbe a full, clear, and exact description of the same.

The present invention relates to mechanism for receiving can bddies and iianging the ends thereof, to prepare the same for the double seam crimping of the tops and bottoms thereto, such double seam crimping beingutilized in the formation of what is known to the trade as a sanitary can, that is a can body having the top and bottom secured thereto by crimping, in contra-distinction to a can having the tops and bottoms soldered thereto.

The hereinafter described mechanism is adapted for the -flangingof either end 0i a can body; hence the machine s especially adapted for the use of packersgenf erally employing cans for the placing of their goods upon the market. Ordinarily, the canis supplied to the packer or canner with its bottom double seamed thereto7 the upper end of the can body being outwardly langed to receive a head, after the can has been filled,

i the cans after being filled having their heads crimped thereon to form a double seam. The serious objection to the cans th'us supplied to the packerfiesides in the ia'ct thatlthe formed end flange is mashed or otherwise damaged or injured during shipment and transportation; hence it is ottimes impossible to properly secure the head to the can after the same has been filled or packed.

- .By the use of the presently described apparatus, the

'empty can is'supplied to the packer with its opened end unianged. l The can after being filled or packed, is

I then delivered to the Hanging machine, and its opened end" properly flanged to receive the can head to be applied thereto, said head being crimped and double seamed thereto by means of an apparatus to form the subject of a separate application. l

To comprehend the invention, reference should be had to the accompanying sheets of drawings, wherein-Q Figure 1 is a side view of the machine in elevation,

the central drive sleeve on the fixed vertical spindle,v

and the bearing sleeves keyed thereto being sectioned, one of the can clamping devices being illustrated in an `opened posltion, Wh1le` the oppositely dlsposed can clamping device'is shown closed `for the holding of the can, the can end flanging 'means for the closed can clamping defzice being in lowered position, the fixed cam grooved disks. being sectioned, likewise the supporting spider carrying the rotating means for the fianging rolls; Fig. 2 is a top plan view of the apparatus, disclosing the eed'device for suppiying the cans onto the rotatable receiving table, and tlie means for removing Patented July 2, 1907.

the flanged cans from said receiving table; Fig. 3 ida cross sectional top plan view disclosing the receiving drawings; and Fig. 4 is a broken detail enlarged part sectional view disclosing one of the can end fianging means, said'view illustrating a can held to., l e rotatable receiving table, the plunger of the clampin' means lowered, and the mandrel he'ad thereof withinthe open end the open end ofthe can above the mandrel held therein, the means for actuating the vertically movable longer, lthe means for imparting rotatiori to the rotatab e sleeve being disclosed.

Referring to Fig. 1 ofthe drawings, the numeral 1 is used to designate a vertically'r arranged spindle, which serves as a guide post for the rotatable drive sleeve-2,

keyed a bevel v'gear 3,which gear is driven to rotate the sleeve 2, by means oi the pinions 4, said pinions being in any suitable manner. Two shafts and two drive pinions are illustrated, simply to permit of the machine being driven from either side. The drive sleeve 2 extends through the base plate 6, which plate carries the brackets 7 for the bearings 7, said brackets also being secured to the bearingA 8, to which the guide post' 1 is keyed. To this base plate 6 is securedthe cam grooved. ring 9, within the upwardly inclined cam groove 10` of l which work the rollers 11, of the hereinafter Vdescribed rods 12. Each plunger rod 12 extends through the receiving table 13, the hub 13 of -which is keyed to thc drive sleeve 2. This receiving table is held a distance above the plate 6, by means of the hub 14, o f said plate, on which the hub 13 of the receiving table bears. The plunger rods 12, four of such rods being shown, Fig. 3 of the drawings, extend through guide openings 15, of a spider 154, which spider is keyed to the drive sleeve 2, so astorotate therewith. Each plum ger rod 12 has secured thereto by a set screw 16, a pro' jecting lift arm 16, the outer end of each arm bei forked to fit within a circular groove 162, formed in the heads 17, which heads carry the Hanging rolls 17', 4 of the drawings. The said heads- 17A are featheredv to the spindles 18, which spindles rotateabout the vertically movable rods 19, each rod at *its lower end calrying a mandrel 20,'Twhich mandrel, when its rod-19 ertical opening 22 in the mandrel said mandrel vsuch portion of the opening being slightly4 enlargedto permit of the head of the screws table, said view being taken on line acl-x 1 of the I carrying the flanging rolls, and the mechanism for actuating the hinged arm carrying the clamp for the can 1 secured to the drive shafts 5, which sha-its are driven` thereto by means of the screws 22. These screws exof the held can, and the Hanging rolls as having 'flanged I tted thereon. To this sleeve, near its lower end, is

is lowered, as hereinafter deseribed,fmoves within Athe open end of the held can 21 to be iianged. The man- 20, the saine being inserted from the under face of the moving into the dovedailed circular groove 23, intercepted `by the vertical opening 22. While the mandrel and rod lf) are supported by the head l?, the said head is tree to turn or rotate without its motion being imparted to the mandrel 20, the said mandrel boing held against rotation by reason oi the rectangular end portion 23', of its rod 15), fitting within a similarly` shaped socket 24 formed in a holding plate 24, secured to the upper lace ol each arm 25 radially projecting from the hub 25 loosely fitted onthe central guide post 1.` Within a vertical guide opening 2G in the outer end portion ol' each arm 2.3, works the upper end oi the spindles 1B. T he spindles 18 rotate within the vertical guide bearings 27, upwardly extending from the spider 15.', and on each of the spindles 18, linmediately above .its guide bearings 27, is keyed a pinion 27. These pinions nxosh with a gear ring 28, the huh 28" oi which gear ring'is keyed to the upper end` portion of the central guide post 1.

To thc guide post l, immediately below the hub ol' the gear ring 28, is secured the hub 2l), of thc disk 29, Fig. l of the drawings. ln the under lace of this disk 29', is formed the circular calo groove Tit), within which work the rollers 30. These rollers are secured to the studs 3l, upwardly extending from the inner end por tion o f the slide blocks 32. These blocks arr.- formed with the projecting armor arms 32', which arm or'arms work through beaiingal 323, on the` side of the guide bearings 27,\the outer ends. oi' each arm, there being two shown in the drawings, terminating in trunnion `bearings 3.3i, in which rest the trunnions 34, projecting lrom each hinged clam p arm 34. These arms are hinged tothe guide bearings 27, the lower end ol each arm carrying a can retaining jaw or clamp section 3.1. These retaining jaws or clamp sections are to hold the upper portieri ofv the body of the can 2l, firmly into its fixed 'jaw or mold 35, which mold is secured by a bracket portion 36, to the rotatable receiving table lf). In height the mold or jaw 35 is slightly less than the can body to be llanged, the retaining jaw or clalnp section 35, when thrown downward by the action of its yClamp arm 34", completing th c ring which compresses the upper end portion ol the can body 'circumferentially and trucs the same, in case the can body should be mashed by handling.

,"I'he cans 21, tilled oriempty, are delivered onto the irritating receiving table 13, by means of any suitable 'i .,eedvconveyer, or device 37, the lower moet can of the serien contained therein being removed and forced onto of the Iixcd molds or jaws 35.

the table 13,`thc moment the same ia engaged by one After the can 2l to be flanged has `'been removedirom the feed conveyor il?,

ontothe receiving-table 13, the said table will have rotated to suchaposit'ion to carry the roller 30', for actuatingithe clamp arm 34, carrying the' companion Can'jaw flwhich registers with the lixed rnold or jaw 35', `intothe inwardly inclined portion of cam groove swung downward, itil cam jaw or clamp section 35` vengages the upper end portion of the can body and forces the said can body firmly into the tlxed retaining "30, the-@travel o the said roller fl within auch portion jaw or mold 35. At the same time, dA a Ato the con tinuedrotation o the receiving table, `the roller 11, of the plunger rod l2 connected with tli'elactibn of the described clamp devices for the can bod'y, rides within the downwardly inclined portion el thecam groove 1t),

plunger rod 12 is drawn downward. This movement oi the plunger rod 12, through the medium of the 'arm 16', carries therewith the head 17, feathered on the rotating spindle 1 8, and draws downvrafrl the rod 19, forcing the mandrel 20 into the open` ndef the can body. With the dolwnward movement f the Hanging rollsmlircazjricdaround bythe rotation of the head 17, whigh, as stated, is feathered to the r0tating spindle lffregradually moved downward against the projecting end ol the can body rigidly held between the clamping jaws, and the end of the body above the mandrel 20,' is gradually outwardly flanged, so that byf the time the head 17 `has moved its full downward dis-l tance, an outwardly projecting cireularange 38, for the" open end of the can body isformed, Fig. 4 of the drawings. Inasmuch as theaction oi each ofthe series o flanging devices is the same aa the described movements; no lattempt has beenfmade to follow other than the action of one oi thc-.clamping `and Hanging means, it being understood that the successive means receive the cans to be flanged,` clamp the same and outwardly flange the open end in the manner just deacribed, the action of an y one set :of operative parts being the same as that of the remaining ones ol `,the eries.r

Where the apparatus is used to flange the open end of filled cans, the 4downward movable mandrel 20, serves to firmly compress or pack the material therein.

'lhe moment the end of the can body has been properly flanged, the roller ll, l'iylthe continued rotation ol the receiving table, will have moved into such a position within the cam groovi,l 1U, as to ride upon the upwardly inclined portion ol the, said cam groove, which im parts a reverse movement to the plunger rod l2, lifting the same so as to move the head 17 upward?, and lifting the Hanging roller# 17 and the mandrel 20 clear of the flanged can body. .Xt the Same time, the roller fit1', controlling the action of the hinged clamp arm .'ifl, rides upon the outwardly inclined portion 'of the earn groove H0, forcing its slide block 32 outward, which throws the hinged clamp arm 34 upward, thua moving the clamp jaw Ti-awayrom the flanged can, and leaving the same free within its seat., mold or jaw The can thus treed is engaged by the curved delivery linger 38, which gradually forces the flanged can. from ofi the receiving table onto the delivery belt 39. The hanged can is then ready to be taken to any Huitable mechanism for applying the head thereto.

'lhe requisite rotation is imparterlto the Hanging rollers by the rotary motion ol the pindle 18, which :lipindle is driven by the pinion 2T thereof meshing with the teeth of the lixed gear ring 28, as' the said pinion is carried around the'gear ring by the rotary l travel oi the spider 15', which spider is propelled during the rotation of the receiving tablel 13, by reason ol its connection w'itlithe drive sleeve 2. i By reason o the connection between the propelled pinion 27" of the spindle 18 and the stationary gear ring 28, the said spindle 18, carrying the {langingrollers l7, will be rotated at a muc-lr higher speed than the drive Sleeve 2.
