firigiiial application filed lvlarch 31, 1917, Serial No. 158,791. Divided and this application filed June 5,

' 1917. Serial No. 173,041.

To all whom it may concern:

Be it known that I, WiLLIAM M. MI'roHnLL, a citizen of the United States, and resident of Louisville, county of Jefierson, and State of Kentucky, have invented certam new and useful Improvements in Anticreeping Devices for Railroad-Rails, of which the following is a specification.

The present application is a division of an earlier application, filed by me, March 31, 1917, Serial No. 158,791.

The invention relates to anti-creeping devices for holding railway rails against longitudinal movement, and seeks to provide a simple, eli'ective construction which is securely fixed to the rail, and which preferably also acts as a tie plate. The invention consists in the features of improvement hereinafter set forth, illustrated in the preferred forms in the accompanying drawings, and more particularly pointed out in between them, and then permit the engagethe appended claims.

in the drawing Figure l is a plan view of one form of the present in ention;

Fig. 2 is a cross section on the line 2-2 of Fig. Fig. 3

and

Fig. 4.- is an end view, parts of the rail being shown in section on the line M of Fig. 3.

The form shown in Figs. 1 and 2 comprises a plate 1 inserted between the tie 2 and the base of the rail 3. The plate is provided, on its lower face, with depending tic indenting portions 4, and, upon its upper face, with raised parts 5 upon which the base of the rail rests. The plate is also provided with a shoulder or longitudinal rib 6 which extends along one edge of the rail base, and the plate is provided with openings for receiving spikes 7 which are driven therethrough into the tie, and the heads of which overlap thin edge portions of the rail base.

The plate or-anti-crceping device is held against movement by the engagement of the spikes with the tie and it is solidly and permanently united to the rail base by welding or fusing the opposite edges of the latter to the :nljacent portions of the plate. Preferably a fillet is fused from a steel rod by means of a suitable cry-acetylene torch and is a plan View of another form;

run into the space between the shoulder 6 and the adjacent edge of the rail base, while the latter are heated by the torch nearly to the fusion point. Such a fillet is indicated at a in Fig. 2, and the metal body thereof is integrally united to the adjacent portion of the shoulder and the rail base. In a similar manner, a fillet b unites the opposite edge of the rail base to the adjacent portion of the plate. y

In the preferred form shown in Figs. 3 and 4, the tie plate 8 is provided at diagonally opposite corners with upwardly and inwardly projecting lugs 9, and at the other diagonally opposite corners, the plate is provided with holes for receiving retaining spikes 10. The lugs 9, together with the body of the plate, form jaws which are arranged to embrace the opposite base flanges of the rail, the space between the aw lugs 9 being sufficient to receive the base flange ment of the jaw lugs with the upper face of the base flange by twisting the plate in a horizontal direction. I

The opposite edges of the rail base are welded or fused to the adjacent portions of the plate and the inner ends of the hooks or jaw lugs 9, which overlap the base flanges,

are welded to the upper faces of the base flanges of the rail. Preferably fillets c are fused to the connected parts and extend along the edges of the rail base and along the ends of the hooks or j aw lugs, as shown.

Preferably also, these fillets, at diagonally opposite corners of the plate adjacent the spikes, are enlarged into bosses (Z, which extend upwardly and inwardly over the base flanges of the rail. The improved anchor or anti-creeping device is thus securely united to the rail base without weakening the metal body thereof and efl'ectively 00- operates with the tie to prevent creeping. In the preferred form shown, it also acts as a tie plate. i

It is obvious that changes may be made in the details set forth without departure from the essentials of the invention as defined in the claims.

I claim as my invcntion:

1. In anti-creepers for railway rails, the combination with a rail and its supporting cross tie, of a plate interposed between the tie and the rail base and spiked to the tie.

messes mg a plate interposed between the tie and the base of the rail spiked to the tie, said plate having lugs overlapping and Welded to the opposite ease flanges of the rail.

3. In anti-creeping devices for railway rails, the cembination with a rail and its supporting cross tie of a plate interposed between the tie and the rail base and spiked to the tie, and metal fillets fused 0r Welded to the opposite edges of the rail base and to adjacent portions of said plate, said fillets being extended upwardly over and Welded tethe upper faces of the base flanges oi the re K In testimony whereel" l affix my signature.
