DOUBLE-SEAMING MACHINE.

an automatic, continuous, rotary, 'double' seaming (machine of a simple, efficient and durable construction, by means of which can headsmay be very rapidly and cheaply double samed upon can bodies and hermetically tight seams produced. i

The invention consists in connection with a continuously rotating carrier turningoii a horizontal axis', and having a plurality of horizontally dis osed can vbody receiving pockets intowhic the can bodies may feed by lgravit-y from a chute into the pockets of the carrier as the carrier rotates continuously, a plurality of airs of axially rotatable can holder chucks mounted `on t-he.carrier, one

pair for each pocket of the carrier,` a plurality of sets of' independently movable double seeming rollers-mounted on the car# rier, one set for each pocket of thepcarrier, stationary cams and connectioiisffo'r automatically operating the several sets of double seamlngollerjs as the carrier rotates continuously, a stationary cam and connections for reciprocating one fof the rotatable can holder chucks of eachlpair'as the carrier rotates continuously, and means for axially rotating .the rotatable can holder chucks as the carrier revolves.

'lhe invention further consists in thel novel constructionof parts `and devices and -v in the novel c binat-ions of arts and devices herein sh ,wn and descri -d and more particularly specified in the claims.

gether before being fed Vto the machine in cases where it is not desired to feed the heads and bodies separately tol the machine or to employ or use a can head chute separate from the can body chute.

In the drawing, 1 represents the frame of the machine, the same being of any suitable` construction to give support to the other parts.

2 is a continuously rotating carrier, turning on a horizontal axis or shaft 3 and haying a plurality of horizontally disposed can body receiving pockets-1, preferably sxin number. The carrier 2, for convenience of construction` preferably comprises four separate disks or heads 5, 5 and 6, 6, thetwo inner ones 5, 5 having 'formed therein the can body receiving pockets l, and the two outer ones 6, 6 carrying the can holder chucks and seaming roller mechanism.

A plurality of pairs of axially rotatable can holder chucks 7, 8 are .mounted on the,

carrier 2,. one pair for each can body re- One of the eeiving pocket of the carrier.

Vcan holder chucks 7 of each pair has a spindle or shaft furnished with a gear 10, which meshes witlra main or central gear 11 to axially. rotate the can holder chucks and the'can clamped between them as the carrier 2 rotates. The shaftorV spindle 12 of the other chuck 8 of each pair has a rotatable connection, preferably a ball bearing connection 13 eomprisingballs and a ball race, with an adjustable member 14l of'a reciprocating Vstem 14 which is( furnished with an anti-friction roller 15, engaging a stationary cam 16 on the frame of the machine by which the can holder chuck 8 is reciprocated as the carrier 2 revolves to clamp the can between itself and the opposingchuck 7. A spring 17 is preferably interposed between the can holder chuck 8 and vits reciprocatin stem 14 of .stem 14 to accommodate variations in length of the can bodies 'and give a yielding clamping Vact-ion An adjust-.

to the can holder chucks 7,-8. ing screwv 18 is also preferably interposed between the can holder chuck 8 and its reciprocating .stem 14 for adjusting the can clam ing `1u0vement of the reciprocati chuck) 8. A spring 19 acting againstv a p 20, carried by an'ar'm .21 on the stem 14 is preferably employed to open thel chuck 8 asy the carrier revolves into position to re chute 22.

rllhe cont-lnuouslv rotatine carrier 2 is rovided with a plurality of setsof'movable double seaming rollers 23, 2e, one set for each can body pocket lof the *carrier 2. One of the double seeming rollers 23 of earch set serves to turn, or fold the flange 25 of the can head 26 over the flange 2? of the can body 28, and the other searning;- roller 24 lserves to finishl the seaming operation or compress the folds of the seam closely and tightly together.

The movable'seaming rollers 23, 2e of' each pair are each mounted upon an vindependently movable tool holder 29. prefer,- ably a vibrating,` arm on roch. shariJ 30, and having` an adjustable connection 3l with the rock shaft arm 32, the rock shaft being provided With a further arm 33, carrying an anti-friction roller 3e which. engages stationary cams 85 and 36, one cam being employed for operating the forming rollers 23 and the other for operating the nishing rollers 24.-. The stationary cams 35, 36 are preferably on a stationery hub 37, secured to the frame ofthe machine and spi 'i 37 are preferably used to retain the rollers Bil in engagement with the cams 35, 3G.

The shaft 3 of the carrier 2 is preferably continuously rotated from the main driving shaft 38, l :wing fast and loose pulleys 39, 40, through. Athe intermeshing gears lil, 48 and 44, the gears 4-2, 43 being on the intermediate shaft e5.- The main or central gear l1 by which the can holder chucks are axially rotated as the carrier 2 revolves, is

preferably a driven gear instead of a stationary one, and is preferably driven by a gear 4:6 on the shaft 45,"ineshing` with a gear 47 on the hub 4:8 of the gear ll.

, The can body feed chute 211 is preferablyarranged substantially upright so that the can bodies will readily feed down it by gravity, and it is preferably provided with,

i a vibrating feeder or dog 49 to cause the inclination, so .that the can heads may feed down Lhefsame by gravity against tie can head registering pins or stops 52 with Which the carrier 2 is provided to cause each can head to properly register with its can body before 'the can holder chucks 7, 8 close upon the same to clamp the can head on the canv body preparatory to the seainingy operation. YThe can head feed chute 22l is preferably furnished with a vibrating can head feeder or finger having an arm 5d operated by a cani or projection 55 on the carrier 2 as the carrier rotates, and thereby releasing the lowermost can head in the can. head chute. rlhe length of the contacting face 54a of arm tel is such that the feed linger 53 is only Withdrawn long enough from the path of the can heads in the chute 22 to permit the release of but a single can head at a time, a spring 54;"l operating to restore the feed finger 53 to normal position e soon as the projection 55 passes the contacting face 5e* After the can head has been seemed upon the can body by the'operation of the machine, the :finished can is ejected or deliyered from the machine intothe discharge chute 56 by the egector device 57 which projects into the path of the can bodies on thel carrier 2. f

In practicing the invention, it is preferred to feed the can bodies and can heads separately to themachine and to employ tliio chutes for this purpose, one for the can bodies and the other for the can heads. lf, however, the heads and bodies are irstassembled together and the flange 25 of the 'can head crimped or clenched at two or vmore points of its'circumference, as at 58, about 95 `the Hangs of the can body, the assembled can heads and can bodies may be together fed to thel machine through the can body chute 211, vand in such case, the can head chut-e 22 need not be used or may be entirely omitted from the machine if desired.
