' ANTICREEPER FOR RAILROAD RAILS.

Specification of Letters Patent.

Patented July 31, 191?.

Application filed May 7, 1917. Serial No. 186,874.

To all whom it may concern Be it known that I, lVILLrA M M. MITCHELL, a citizen of the United States, and a resident of Louisville, county of Jefferson, and State of Kentucky, have invented certain new and useful Improvements in Anticreepers for Railroad-Rails, of which the following is a specification.

The invention relates to anti-creepers or rail anchors for preventing the longitudinal movement of railroad rails. To avoid cutting, perforating or otherwise weakening the "rail to receive attaching rivets or the like. rail anchors now in use are held in position by a friction grip of one sort or another. But it has been found difficult to provide rail anchors of this-sort, which will effectively maintain their grip on the rails under all working conditions.

The present invention seeks to overcome the difficulties above noted and to provide a rail anchor adapted to abut against the tie and which is solidly united to the rail by welding or fusing without weakening the metal body thereof. Further objects of the invention are to provide a rail anchor which can be manufactured at very low cost and which can be readily and inexpensively applied to the rails by welding or fusing.

The invention consists'in the features of improvement hereinafter set forth, illustrated in diflerent preferred forms in the accompanying drawings and more particularly pointed out in the appended claims.

In the drawings Figure 1 is a plan view of one form of the present invention. Fig. 2 is a side View thereof. Fig. 3 is an enlarged section on the line 33 of Fig. 1. Fig. 4 is a view similar to Fig. 3 illustrating a slightly different manner of applying the rail anchor. Figs. 5 and 6 are plan views illustrating modifications. Fig. 7 is a cross section illustrating another modification.

The improved anchor is constructed of forged or rolled ironor steel and is preferably of simple form comprising only a tieabutting portion and a portion at an angle thereto extending beneath the rail base and outwardly beyond the edge portion thereof and securely fused or welded to the edge portion of the rail base. Such anchors can be inexpensively made from rolled iron or steel bars of different shapes or indeed from pieces of scrap.

The form shown in Figs. 1 to 4 inclusive comprises a vertically disposed'tie-abutting member or flange 1 and a vertically disposed flange 2 which extends rearwardly beneath the edge of the rail base 3 and the upper part of which is welded or fused to the rail.

part or lip 5 which extends over the vertical edge face of the rail base. The anchor can be welded or fused to one of the base flanges of the rail before the rail is laid, but preferably it is applied to the rail when the latter is-in position in the track. I When this is done a portion of the base flange of the rail adjacent the tie, is heated nearly to the fusion point by a portable heating device such as an oXy-acetylene torch. The anchor is then applied in position with the member or flange 1 abutting against the tie 6 and with the shoulder 4; extending beneath and 1n engagement with the lower horizontal face of the rail base, but preferably the inner ,7 I

face of the upwardly projecting portion or lip 5 is spaced to a slight extent from the adjacent vertical edge of the rail base. The adjacent portions of the lip 5 and edge of the rail base are then securely fused together by a fillet of metal as indicated at a in Fig. 3, the metal fillet being solidly united or in corporated with the metal of the adjacent portions of the rail base and anchor.

If desired, the fillet may be formed by using the oxy-acetylene torch to fuse adjacent portions of the edge of the rail base and of the lip or portion 5 of the anchor, but preferably the fillet is fused in part from a steel pencil or rod and run into the space between these parts. If desired, the portion or lip 5 may be omitted and the uniting fillet formed between the edge of the rail base and the horizontal face of the projecting upper edge portion of the member 2, as indicated at a in Fig. 4.

, In this Way, the anchor is readily and soldidly secured in position Without in any way weakening the metal body of the rail. Obviously too. the anchor is permanently it cannot be discontraction or by of the rail. away from the be dislodged by the poundaud vibration due to the passage of city traliic over the rail.

he anchor thus efiectively prevents ping of the rail in the direction indicatcd by the arrow in Fig. 2. The reaction thrust of the rail on the flange or member sisted the flange or member 2 which forms a brace between the tie abut merit and the rail engaging portion that extends beneath the edge of the rail base. refera cree oly, boss Z) of metal is welded or c to the upper face of the rail base and to the upper portion of the anchor at a point adjacent the tie. This boss may be formed in piece with the anchor before the latter is applied, but it is preferably built up when the anchor is applied by fusing a steel rod or pencil. lhis boss serves to aid in resistingthe reaction thrust of the tie upon the anchor and thus strengthens the welded joint. Preferably also, as most plainly shown in Fig. l, the tie-engaging abutment member 1 extends both beneath and to one side of the rail base to a. substantially equal extent on opposite sides of the welded joint and the latter is thereby relieved of horizontal twisting strains.

The term shown in 5 is similar to that previously shown and described except that tie-abutment member 7 extends on one side only or" the member 2 so that the anchor can readily formed of a section of an angle bar. The form shown in Fig. 6 is like that shown in Figs. 1 and 5 except that it is formed of a section of channel bar. The tie-abutment member 8 extends entirely honest the rail base and the rearwardly extending flanges or members 9 are welded to the opposite side edges thereof.

Preferably as shown in Figs. 1, 5 and 6 he portions fused or welded to the edge of 1c raillbase are beveled or inclined at their eds, shown, so that they will engage and efiect the wheels of a derailed car that might otherwise break off and destroy the anchors.

The form shown in Fig. 7 comprises a depending tie-engaging abutment 11, a hori zontal rail engaging portion or member 10 and an intermediate hollow bracing portion 12. The portion 10 extends beneath the rail base and projects outwardly beyond the edge thereof and is provided with an upturned part or lip 13 and preferably also with an integral boss ll. In applying the anchor the portion 13 is spaced slightly from the adjacent vertical edge of the rail base and is welded thereto by a fillet as indicated at c. The edges of the boss i i are welded to. the upper face of the rail base by fillets (Z.

it is obvious that changes may be made in the details set toithwithout departure from the esse: bale of the invention as defined in the claims.
