application filed October 9, 1909; hserial No. 521,909.;

To all wh om may concern:

Be it .known that I, Wnmuu H. MORGAN,

of Alliance, in the county of Stark-ind State of Ohio. have invented certain new and useful Improvements in Methods of and Machines for Flanging Plates; and I do hereby declare the following to be a full, clean/and exact description of the invention,- such as will enable others skilled in the art to which it appertains to make and use the same.'

My invention relates to an improvement in the method of and apparatus for Hangingbeams or plates.

\Vith the ordinary grooved rolls, such as are nowcommonly used for rolling flanged beams, the depth and-width of thetlanges, rolled thereby, are, owing to the differences in speed of portions between the axis and' peripher; otthe rolls,'positively limited and tixed. Universal mills for producing larger beams with larger flanges, have been constructed. but owing to their many parts, and

the cost. of. and power required for operating them, their use is confined exclusively to the larger plants.

The object of my invention is to provide a comparatively simple apparatus adapted to he used in connection with an ordinaryplate mill, for Hanging plates of any-width, and for forming flanges of any reasonable width and thiclt'ness on said plates. and my invention consists in a clamp for holding' a rolled plate leaving the edge thereof exposed, and Hanging or swaging devices mounted to move crosswise the edges of the plate.

My invention .turther 'consists in means for holding the plate to be flanged and conical swaging dcvices mounted to move cross wise the edges of the plate. and in contact with the latter. I

My invention further consist: in means for clamping a plate. means for feeding the latter in a step by step movement, and a swag'ing device mounted in a cross head and adapted to travel trai'isverselvto the direction of movement of the plate.

My invention further consi ts in dies for holding the plate to be flanged and a swag-- ingdevice mounted to travel in' a-dn"ect!on l at rnglztmu-ih-s to the direction of feeding movement of (ht-plate and in contact with I i l I I the edge thereot, whereby the pro ecting ends of the plate will be forced or swaged into the r flanges;

In the accoinpain ing draw gs. Fig'gur'e l.- a view in vertical section through the apparatus.- Fig. 2 is a view in transverse verticalsection. Fig'. 3 a view in plan. Fig; t is a view in plan of the details, of the feed .60

tion of thelatter. t: 3 s t i i 1 represents a hon. 11g shaped as shown ,in.

'Fig's. 1 and 2 and carrying the shafts l and 1 '3, the'ft'n'merof which-extends through the '65:

e'xt'e'nds part way only. The h iper shaft is "tlriven "by -motor -t and gem-si t) and 3(- the latter of which is in'oun ted on the squared 1 end of shaft 2'so asto pen-nit the latter to .t l u be adjusted or moved lengthwise as, w ll he hereinafter explained -flhe opposite end of. I

shaft 2 is also sq'uared and carries t oothed wheel 7 meshing with pinion8 on the square end of shaft 3. I

Located within the open. center 0f..the no'usiug 1, are the adjustable column guides 9 through which theshafts Zand 3 passand. on whichthe crossheads 10 arevv moun ed to reciprocate vertically. As shown; in Fig. 1, these column guides are in then extreme outer positions for the largest ,size plate that can be flanged in vthemachine',:and-they'are i designed to be adjusted toward eachother,

for smaller size plate by the screws 11. passmg ,througlrthe housing.and col-mected at their inner ends to the column guides. The upper shaft 2 is provided with a crank-12 carrying a p1tman13 connected atits lower end to one cross head: 10, and the "-l()\\'(3l' shaft. is provided.- withla similar c 'a nk- 12 carry1n a p tman .13, conm-etcdat its'aupper end to the other cross head. 'The'cranks.

' are so arranged. that; both cross heads move up and down simultaneously.

14 represents the upper die and 15 the lower die, shaped to receive-the plate to .be flanged, and provided with recessed sea-ts into which the metal at the sideedees of the.

plate is forced by the swaging devices to hereinafterreferred to.-

These dies aresecurcd tothe blocks 16, each .of which has a roller 17-.- one ofzwlnch latter bears againstv the double throw am 18'on the'upperv shaft 2, wlnlethe lo\ver,o'ne rests-on the cam 19'105 on the lower shaft3, the cams operating to force the dies against the plate and clamp the latter while the swaging devices are moving over the edges of the plate to form the flange. Each cam is in effect adouble cam, in that it 'forces'its block and discarried thereby, against the plate being flanged, twice at each revolution of the shafts. Each complete revolution of the shafts 2 and 3 move the cross heads carrying the flanging or swaging devices up and down. and as there is a feeding forward of the plate just prior to each up and down movement of the cross heads, it will-be seen that theplate must be ,freed at the end of each movement,

and clamped during each movement of the cross heads carrying the flanging or swaging device's.

The cams 18 are of greater length than the rollers 17 so as to providefor adjustment of the parts'for plates of diflerent widths. To adjust the parts from that shown in Fig. 1, for smaller dies to flange a smaller plate, the two column guides 9 flanging apparatus by roller tables, and to withdraw the dies from the plates in order 'to free the latter from the feeding movement, I haase provided the upper block-16 with 'later fily projecting fingers 17 .to which the springs 18* are secured, these springs being suspended from stirrups 18 mounted on the shaft 2. 'These springs are designed to lift the'upper die and its block and cause the roller on the latter to stay in release the lower die in the event the latter should stick to the .plateQ It will therefore be seen that the plate is freed from the dies both on the ascent and the descent of the cross heads, and the longitudinal feed of the plate takes place each time the latter is freed from the dies,

. The plate rests on roller tables on opposite sides of the housing 1 and on the entrance side it passes between the feed rolls 21 which latter are adapted to bear;against the opposite sides of the thickened edges of the plate to be flanged. These feed rolls 21 are mounted on the pivoted levers 22 which bolt- 23, the spring 24'bearing against the hcadot' said bolt and one of said levers,

pperating to yieldingly hold the feed wheels in contact with the plate. Each feed wheel is provided with a ratchet 24 engaged by a pawl 25, the latter being yieldingly held in contact with its ratchet by a spring 26.

Each lever 22 projects inwardly toward the cross heads 10, and the inner end of each lever rests in .the path of a finger 27 on the cross head, so that as the cross head ascends, its fingers striking the pawl carrying lever. of they upper feed rolls, turns the latter in a direction to feed theplate toward the dies, and upon the descent of the crosshead their lower fingers coming in contact with the levers carrying the pawls of the lower feed wheels turn the latter in a direction to feed the plate toward the dies. It will therefore be seen that this feeding movement of the plate is progressive or step by step as the plate is released from the dies, so as to bring the projecting edges 28 of the plate into the path of movement of the laterally movable flanging or s'waging tools 29. The dies are necessarily as wide as the plate to be flanged, but they need be no longer than the Hanging or swaging tools 29, and as shown are located between roller tables on which the projecting ends of the plate rests while being flanged. The two tires are recessed at their ends as shown at- 30 into which recesses the surplus metal at the edges. of the plate is forced as shown in Fig. 1 to form the flanges. The swaging tools 29 are conical in shape throughout the major .por-' tion of the lengths and are cylindrical the remaining portions, and are mounted in the vertically sliding cross heads 10. These tools are arranged horizontally and the plate is fed toward the apices or smaller ends of the cones, the construction being may be again heated if necessary. and if desired, a furnace may be located adjacent to thedies, and through which the plate will pass on its way to the-dies. After the plate has been properly placed between the dies. the roller tables and feed are started .thus moving the plate step by step. but rapidly toward the swaging tools 29. As the end of the plate makes contact with the tools 29, the conical ends of the latter, gradually re duce the stub edges 28 of the plates, until the.

of the flan es.

." The fee ing movementof the plate takesplace after each half stroke of the cross stroke of the cross heads, the plate will be fed a short distance forwardly thus bring- I ing the entire edges 28 of the plate, by a 1 might be resorted to in the relative arrangeneed be only suflicient to clear the outer flanges of anywidth.

step by step movement. into the path of movement 'ofthe tools 29. .The two tools I 29 are located to operate on the two edges of the plate simultaneously. hence each tool f operates as'a brace or stayl'or the other thus" taking to a greatextcnt the lateral' straiii'from the dies. Thelateral movements of thetools with relation to the plate 1 heads carrying the tools. so that at each half I flanges of the -plate,'and-as the tools are not driven, but on the contrary are loose andv are-simplyrotated bytheir contact with the plate. it will be-seen that the lateral movement of the tools over the edge offtlie plate simply swages or expandsthe metal down into the flange shapes 30 in the dies 14 and 15. By means of the conical tools reciprocating in'a path at right angles to'the direction of feed of the plate, I canjflange a plate of any length and width. and produce in the drawings I have shown dies and tools for making I-beami. but it is clearly evident that a channel beam can be formed by providing means for moving the tools out of contactwith the flange of the plate during the return movement of the tools, or I can make a Z-beam by moving one tool out of contact during the down stroke and the other outof contact during the up stroke, hence in Hanging shapes iuwhich the flanges are to one side of the web or body, the plate will have feeding movement imparted once at each revolution, instead of once at each stroke of the flauging tool. i It is evident that. many slight changcsi ment of parts shown and described withoutdepartiug from the spirit and scopeot' my 1 invention hence I would have it understood 3 that I do not wish to confine myself to the exact construction andarrangement of parts shown aiulilcscribed. but.
