\VILLIAM H. PHILLIPS, OF JENKINTOVN, PENNSYLVANIA:

RAlL-BENDING TOOL.

SPECIFICATION forming part of Letters Patent No. 399,630, dated March 12, 1889.

Application filed January 14, 1889. Serial No. 296,258. (No model.)

To all whom, it may cone/27w:

3e it known that I, \VILLIAM II. PHILLIPS, a citizen of the United States, residing at Jenkintown, Montgomery county, Pennsyl- Vania, have invented certain Improvements in Rail-.llending Tools, of which the following is a specification.

The object of my invention is to construct a rail-bending tool that will bend the rail in either concave or convex form from one side of the rail, a further object of the invention being to so construct the tool that it can be used for other purposes than bending rails for instance, as a rail-lifter or jack.

Referring to the accompanying drawings, Figure l is a perspective view of my improved rail-bending tool. Fig. 2 is a plan view of the same. Fig. 3 is a transverse section on the line 1 2, I1 g Fig. 4c is a view illustrating its use as a lifting-jack, and Fig. 5 is a view illustrating its use as a rail-litter.

A is the frame of the tool, formed of the back bar or beam, l3, and side bars, 0 C, these side bars being enlarged at their outer ends, a, and having undercut recesses 1), preferably of the shape of the rail, the lips I) being sufficiently far apart to allow for the insertion of the head of the rail in the undercut portion. These lips pass in under the head of the rail, so that the pressure applied comes upon the heaviest portion of the rail.-that is, the head.

Projecting from the central portion of the beam I a stud, D, having a screw-thread thereon, and to this stud is adapted a long which is also adapted to a screwthreaded stem, F, of a head, G. This head G has an undercut recess, g, the lips ff of the head G being suificientlyi'ar apart for the insertion of the head of the rail, and, like lips Z) of the arm (i, fitting snugly the head of the rail to be bent.

The thread on the stud I) is the reverse of that on the stem F, so that on turning the nut E in one direction the head G will be moved toward the beam. B, and by turning the nut in the opposite direction the head will be moved i'rmn said beam.

The rail to be bout is placed as shown by full lines in Fi 2, and a large wrench is ap plied to the nut, which may be of any form, either square or hexagonal, or may be a pinrail will be bent as shown by the dotted line v 2 in said figure.

The usual method of bending railroad-rails is as follows: \Vhen a convex curve is required, the tool is placed between the rails of the track, and when manipulated will give a convex curve to the rail; but if the rail is to be bent in the opposite direction the tool has to be placed outside the rails of the track. It frequently happens, however, that there is not suiiicient room between the outside of the rail and the embanlunent or the wall of a tunnel to allow for the insertion and operation of the tool, thus rendering the bending of the rail an extremely diflicult task; but by my invention the bending-tool can be always placed between. the rails of the track, where there is abundance of room for the maniplb lation of the same, and the rail can be bent into either concave or convex form without moving the tool from this position.

My improved tool can also be used as a lift ing-jack or compression-jackfor instance, for raising cars which have become derailed or otherwise in j uredby simply turning the jack upon end, as shown in Fig. -l, and turning the nut to raise the head G, the base of the beam .13 being fiat, and in some cases roughened, so as to form a good bearing-surface. The end 71 ot the head G is also roughened For the same purpose.

In Fig. 5 I have shown the tool used for raising a section of rail and its cross-ties, so as to allow for the packing of ballast under the ties, the rail being caught and supported by the lip f of the head G.

In constructing my tool for use in a frog or switch shop I may dispense with the outer portions of the arms 0, the arm being cut off, as shown by dotted lines in Fig. I, so that this extreme end will not interfere with the placing of the tool at almost any point on a frog or switch.

I claim as my invention- 1. The combination, in a rail-bending tool, of a beam having arms for engaging the rail, a bending-head also engaging the rail, and a stem, F, a stud, D, on said beam, a screw:

threaded nut adapted to said stud D and stem F, a flattened portion, 0, on the beam, and a flattened portion, h, on the head, so that the tool'can be formed into a jack, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

WILLIAM H. PHILLIPS.
