SAMSON FOX, OF LEEDS, ENGLAND, ASSIGNOR TO THE FOX SOLID PRESSED STEEL COMPANY, OF CHICAGO, ILLINOIS.

APPARATUS FOR BENDING AND FORGING STEEL.

SPECIFICATION forming part of Letters Patent No. 448,815, dated March 24, 1891. Application tiled December 4:, 1890. Serial No. 373,596. (No model.)

To all whom t may concern:

Be it known that I, SAMSON FOX, of Leeds, England, have invented a new and useful Apparatus for Bending and Forging Steel, of

which the following is a full, true, and exact description, reference being had to the accom panying drawings.

This invention relates to au apparatus for simultaneously bending both ends of a chan- Io nel-beam into a rectangular box shape by means of a machine Working in a horizontal diagonal position. By this apparatus both en ds of a channel-bar may be bent sim ultaneously or not, as required.

My invention will be readily understood from the accompanyingdrawings, in which- Figure 1 is a half-sectional plan of themachine. Fig. 2 is a section through Fig. 1 on the line x. Fig. 3 is a section through Fig.

2o 1 on the line yy. Fig.4isaplan of the meeting dies, showing the commencement of the bending operation; and Fig. 5 is a plan view of two traveling furnaces for heating the ends of the beams.

t is the bed or frame. l

jj are saddles set at an angle of forty-[ive degrees to and sliding on the bed or frame t.

157;; are right and left handed screws for adjusting the saddles to the length required.

3o m m are hydraulic cylinders.

m m are rams.

n a are dies, and a" a die-blocks.

o is a channehbar under treatment.

p p are strips for holding the bar securely in position.

vA channel-bar whose ends are to be bent is heated at both ends, then is placed with one end extending to the required distance beyond each of the die-blocks n. 'll`hen the rams with their dies n n are advanced from `4o the positions shown to the leftin Fig. l to that shown in section to the right in Fig. l, thus effect-ing the bending operation, after which the dies are retired, to be in readiness for a succeeding operation.

It will be evident that by using die-blocks and dies of appropriate forms the bending may be effected to any desired angle or curve.

That I claim as my invention, and desire to secure by Letters Patent, is-w 5o l.. The combination, 'in an apparatus for simultaneously bending both ends of a channel-iron, of two dies andan apparatus for advancing them in a line at an obtuse angle to the length of the channel-iron, substantially as described.

2. The combination, in an apparatus for simultaneously bending both ends of a chan nel-beam, of the bed-plate -and two saddles adjustablymounted thereon,substantially as 6o described.

3. The combination of the bed-plate, two saddles mounted thereon at an angle to the bedplate, and a right and left handed screw for simultaneously adjustingthe saddles, substantially as described.

In testimony whereof I have signed my naine to this specification in the'presence otl two subscribing witnesses.

SAMSON FOX.
