Specification 'of Letters Patent.

Application filed September 12,1911. Serial No; 648,848.

To. aZZw 710m. it may concern Be it known thatv I, FRANK. J. SMITH,

citizen of the UnitedStates, residing in the city and county of San Francisco andstate of California, have invented new and useful Improvements in Can-Body-Flanging Mag chines,.of which the following. is a specification. w I y I My invention relates to the class of machines for making the flanges on theends of can-bodies,.which flanges are intended to be assembled. with, the flanges, on the' can heads,- and said assembled flangesloent and doubled together and pressed dow'n in the now well. known operation of double seam? s- The object of my inventionis to provide a simple and eifective machine for Hanging the ends of the can-body, and to this end my invention consists in the novel o'onstructions, arrangements. and combinations of, parts which 1' shall hereinafter fully describe and claim, by reference to the accompanying drawings in which Figure 1 is a plan view of-Iny machine, the 'flanging-heads in the upper and lower positions, and the can feed chute being omitted. Fig. 2 is a vertical section ofthe machine. Fig. 3 is a sectional view, enlarged, of one pair of Hanging-heads, showing; them in position about to operate on a can. Fig, 4 is a. similar view showing. the Hanging-heads pressed in and'the flanges on the can thereby formed.

The frame of the machine is composed of the stand 1 and the end plates 2. Inthe end plates is mounted the main shaft. 3, to which a continuous rotation is tobe applied Upon the shaft .3 are mounted the spidershtwo in number, and here shown as having four arms. In bean ings 5 on the extremitiesof. the armsof'the spiders 4 the stems or spindles 6. of the flanging heads 7 are slidably and non-turn. ably mounted. Their inner surfaces are formed with the annular grooves 11, from v the inner walls of which project the" con atentedflct. 20,1914."

adapted-to receive and. support'thecan-body Q 9 while itiszbeing flanged. The semicircular rests 8' have'grooves 8' in front of the plane ofuthe tape-ring, portions; 12. and extending endwise toward and intersecting with'thebottom wall of-the groovellz It. will 1 now be seen that as the. flanging heads revolve, the'can' bodies restingia-gainst supports 20,. Figs. 2., will; successively drop by gravity onto the successive pairs. of rests 8 of-the. flanging heads. In this position they are itemporarily.held? byan. overlying concentric guard frail-13,. Fig. 2.. As the. op-

Josing flangingheads reach: therupperfpontions of their revolution. about the-shaft-ii', they are moved toward each other from the position shown. 111i.Fig-. 31 to; the position shown inFig h. During this-movement the tapering promoting portions..12. of said heads enter the open ends. of the,- can-body,

formingv itiipcrfectly cylindrical. as itap 'proaches. the largest diameter. As? the ends of the. can bod'y .come' in contact with..the

roundedv cornersofthe grooves 11, theyIare" turned outwardly, forming. flanges, the. I die ameters of which are determined. by the width of thegrooves at. the bottom. Asithe revolution of the machine. continues, the

flanging heads are withdrawn until one. or the other of the. flanges of the; can-body comes in contact with. the: shoulder of the groove 8, and as the Hanging heads. eon-. tinue to withdraw, the can=body will be pulled outof the-opposite fiangingheads-in which it may have jammed; the shoulder ofthe groovethus acting. as anpositive ext tractor; The hanging. heads. having. been carried around bv theshaftzB. to. the. lowerportion of their revolution, and the. rests. 8 of the headsbeinn'. now inverted,; the) cane body, now free,.will drop. 1 out i of said: heads by gravity and move away in. the discharge runway14c. In order toactnate. the flangg' ing heads, rollers 17 are journaled on pins '17, projectingfrom the spindles 6 and these rollers travel 'in' annular channeled cam tracks 18 attached to the plate 2 andwhich are adapted to move the heads to and from each other. \Vhen the h eads reach nearly a point where "the flanges begin to be formed on the can-body; rollers 15, which are journaled-in the ends of the spindle 6, come in contact with adjustable camgtracks 16 on the plate 2, Fig. 1, which force the heads toward each other and from the flanges. This is to exert a direct pressure on the center of the heads, and this cam does not extend beyond where it is required to do this work. In order to secure a proper adjustment of the flangin ried by adjustable screw-hangers 19,

An important feature in this invention is the positive, eifective and accurate structure which extracts the flanged body from the flanging heads and bring it to a position where it will be free to move, out of the machine. This structure comprises the peculiarly designed seats or rests 7 with their segmental, internal recesses 'or grooves 8. When the flanges have been formed and the heads move apart, one or the other of the shoulders of the groove 8 will abut the adjacent body flange, and then further movement of'the heads will pull'the other flange from the channel or groove 11 in the other head until thecan-body isentirely freed, asi'ndicated at the lower part of Fig. 1.

Having thus described my invention,

what I claim as new and desire to secure by Letters Patent is I 1. In a can-body flanging machine, the combination of apair of opposing flanging heads, each head having a portion of its inner side extended a substantial distance to form a segmental rest, tor'eceive' and support the can-body, and each head having also in its inner face an annular groove with a tapering portion rigid with the head and projecting from the inner wall of said groove, said tapering portion being adapted to enter the open end of thecan-body, and the groove being adapted to form the flange on said end, means for delivering the can to the heads, means for revolving said heads past the station of can-body deliver and means called into action by the revolution of the heads for forcing them toward and from each other.

2. In a can-b'ody'flanging machine, the combination of a frame, a rotating main shaft mounted therein, a pair of spiders carriedby the shaft, a pair of opposing flanging heads each having a stem slidably mounted in thespider, and each head having a portion of its inner, side extended a substantial distance to form a segmental rest to receive and support the can-body, and further formedon its inner face with 9; head 7, the cam-tracks 18 are car an annular groove and a tapering portion projectlng a substantial distance from the inner wall of said groove, and beyond the and the channeled cam track in-Which the other of said rollers travels.

3. A can-body flanging machine, includinga revoluble shaft, spiders carried thereby, spindles slidable and non-turnable in said spider, and carrying channeled flanging heads, said heads having central projections and-having a portion at one side ofthe projections extended beyond the inner face of the central projection, a chute to guide can-bodies into the path of the heads, segmental rests on the heads upon which the can-bodies are received and from which they subsequently drop to a central position by the revolution of the carrier, rollers upon the flange head spindles, and fixed cams by which said rollers are actuated.

4.1 A can-body flanging machine, includ- I ing a revoluble shaft, spiders carried there by, spindles slidable and non-turnable in said spider, and carrying channeled flanging heads, said heads having central projections and having a portion at one side of the projections extended beyond the inner face of the central projection, a chute to guide can-bodies into the path of the heads, segmental rests on the heads upon which the can-bodies are received, and from which they subsequently drop to a central position by the revolution of the carrier, rollers upon the flange head spindles, fixed cams in which said rollers travel to reciprocate the heads, other rollers journaled transversely in the spindle ends, and thrust cams against which they travel. In testimony whereof I have hereunto set my hand in the Witnesses.
