RAIL STRAIGHTENING IMPLEMENT Filed July 19, 1954 v \uuuuuuuuuin imimi\imiuuuuuuuu PauZ E 1 15mm Patented Jan. 26, i937 UNITED STTES PATENT FFIE 1 Claim.

The invention relates to implements for straightening railroad rails, being particularly adapted for use in straightening the rails in mines, but that also may be used for bending or straightening bars, pipes, and the like, and that has for its principal object the provision of an implement that is reasonable in cost of manufacture, that is extremely efiicient in operation, that is simple in construction, and that is of minimum weight so that it may be readily transported from place to place in the mine for operation in straightening the rails of a mine track, and as the device takes up a minimum amount of space when set up for operation may be readily used for the purpose stated.

The invention will be described in detail hereinafter and will be found illustrated in the accompanying drawing, in which Figure 1 is a. side view in elevation of the improved rail straightener showing it in position on a fragment of a railroad rail,

Figure 2 is an end view in elevation showing the rail in section,

Figure 3 is a transverse sectional view on a plane indicated by the line 33 of Figure 1, and

Figure 4 is a plan view of a Wrench adapted for use in connection with the operation of the device.

In the drawing similar reference characters are used to designate corresponding parts in all the views.

As hereinafter stated the invention contemplates the provision of an implement that may be readily transferred from place to place along the tracks of a mine and quickly set up in position for straightening the rails, and by taking up minimum amount of space is readily adaptable to operation in restricted positions in the mine, the implement having a U-shaped base member I0 that is provided intermediate of its ends with an enlargement or boss H having an opening l2 therethrough to receive a threaded stem l3 of a rigid hook shaped member l4, said hook-shaped member l4 having its bill provided with a transverse flat portion l5 and its extremity with an upturned flange It so as to engage under the base of a railroad rail designated [1.

Mounted on the threaded stem I3 is a nut I 8 that is elongated as shown so as to distribute the strain of the straightening operation over a plurality of threads on the stem and nut to prevent stripping of the threads. i9 is a washer located between the enlargement or boss II and the nut l8, and 26 a preferred form of wrench for use in turning the nut E8 on the stem, but obviously any other type of wrench may be used, the rigid jaw wrench as disclosed in the drawing being suggestive only of the proper tool for the purpose.

The terminals of the U-shaped member I0 are provided with recesses or notches 2| to engage the head of the rail l1, said notches 2| being defined by flanges 22 and 23, the flanges 23 being preferably longer than the flanges 22 and arranged on that side of the notches and of the base member I0 corresponding to the closed side of the hook when in position as shown, so as to provide for ready assembling and removal of the implement relative to the rail.

In operation, the notches 2| engage the head of the rail on opposite sides of a depressed portion therein, and after the hook member I4 is engaged with the rail as shown in the drawing, the rail may be bent and straightened intermediate of the notched ends of the U-shaped member Ill by screwing the nut I 8 down on the threaded stem l3.

What I claim is:-

A rail straightener, comprising a U-shaped member having notches in its ends to engage remote portions of a rail and provided with an opening in its bight portion, spaced flanges on the ends of said member and defining said notches, one of each of said spaced flanges being longer than the other, the longer flanges being arranged on corresponding sides of the notches on the ends of the member, a hook slidably mounted in said opening and having a threaded stem, and a nut on said threaded stern and engaging the member to adjust the hook relatively to the notched ends thereof.
