RAIL BENDER- iled July 51. `193e ATTORNEYS Patented Nov. 30, 1937 RAIL BENDER Raymond P. Jones and Walter A. White,

Application July 31, 1936, Serial N0. 93,708

1 Claim.

The invention relates to a bending tool and more especially to railway rail benders.

The primary object of the invention is the provision of a tool of thisv character, wherein a maximum strength is inherent therein for a given weight of the material entering into the construction of the bender and a yoke for abutment of the ball of a rail has slidably fitted therein a bending jaw, the latter being cam controlled thus enabling the tool to be readily and easily operated and with assured result of proper bending of the Work.

Another object of the invention is the provision of a tool of this character, wherein the same is readily applied to and removed from a piece of work and when applied will enable the convenient bending of such work without excessive leverage on the part of the operator of the tool.

A further object of the invention is the provision of a tool of this character, which is extremely simple in construction, thoroughly reliable and efficient in operation, readily and easily operated, and inexpensive to manufacture.

With these and other objects in View, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention and pointed out in the claim hereunto appended.

In the accompanying drawing:

Figure l is a top plan view of a tool constructed in accordance with the invention showing the same applied to work, the latter being shown in full lines prior to the bending thereof by dotted lines the bent condition.

Figure 2 is a sectional View on the line 2-2 of Figure 1 looking in the direction of the arrows.

Figure 3 is an edge elevation of the tool.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, the tool comprises a substantially half circular shaped yoke 5 having formed medially thereof a guide sleeve 6 while the ends of the yoke are formed with abutment heads or terminals l, these being cut into at their under sides to form seats 8 for the ball or tread 9 of a railway rail I0 of conventional kind.

Slidable through the sleeve 6 is the stem or I shank II of a hook-like jaw I2 which interlocks with the ball 9 of the rail IIJ to enable bending of such rail in the working of the tool.

The sleeve 6 has a matched separable part I3 fitting upon a bushing I4 which is socketed within the sleeve 6 and surroundsthe stem or shank I I. The stem or shank I I at the end thereof remote from the jaw I2 is screw threaded at I5 for adjustably accommodating a cap-like nut I6 which is threaded on this end. I'his cap I6 abuts the part I3 as well as the bushing I4 thus holding such part I3 in association with the sleeve 6.

The sleeve 6 and the part I3 on the inner faces thereof are provided With cam surfaces Il While rotatable upon the bushing I4 between the said sleeve and the part I3 is a cam I8 cooperating with the cam surfaces Il. This cam I8 has a socketed nipple I9 for a handle, a portion thereof being indicated at 28. Thus is will be seen that when the cam I8 is operated in one direction the shank or stem I I will be pulled through the sleeve I of the yoke 5 and in this manner when the jaW I2 is interlocked with the rail I0 the latter will be bent.

The tool is readily and easily applied to and removed from a piece of work and bending of such work is assured with minimum exertion on the part of the operator of the tool.

What is claimed is:

A rail bender comprising a substantially archshaped yoke having a medial sleeve portion provided with a cam end projected outwardly from said yoke, abutment terminals formed at the ends of said yoke, a shank slidable through the sleeve and having a jaw, a double cam-faced collar loose on said shank, one cam face of said collar being in confronting relation to the cam end of said sleeve, a socketed handle extension formed with said collar, a cam-faced part loose upon said shank and confronting the other cam face of said collar, a cap threaded on the shank and acting against the part, and a bushing about said shank and socketed within the sleeve for the fitting of the collar and part thereon With the cap in abutting engagement with said bushing.
