T0 all whom it mfr/y con/cern:

Be it known that I, JOHN BUCKLE LEIGHTY, a citizen of the United'Statea-and a resident of Cumberland, in the county of Allegany and State of Maryland, have made certain new and useful Improvements in Anticreeping Devices, of which the following is a specification.

My invention is an improvement in devices for preventing railroad-rails from creeping; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of my improved device as in use. Fig. 2 is a cross-section of a rail provided with my improvement. Fig. -3 is a detail perspective view of the hooked bar. Fig. 4 is a detail perspective view of the abutment-section. Fig. 5 is a sectional plan view of the abutment-section. Fig. 6 is a detail section on about line 6 6 of Fig` 2, and Fig. 7 shows a somewhat-different construction of hooked bar from that shown in Fig. 3.

As shown, my invention comprises the hooked piece A, which may be of any suitable shape of material, and the abutment-section B, which operate in connection with the tie O andthe rail D. The piece A is provided at its opposite ends with the upturned hooks c a', adapted to embrace, respectively, the side of the rail-base and the outer side of the cuff portion of the abutment-section. Im-

mediately adjacent to the hook a the upperA side of the bar A may bey depressed or recessed at A to receive the bottom plate of the cu of the section B, so that the rail-base D will be in contact partly with the upper surface of the bar A at A2 and partly with the bottom plate b of the cuff Z) of the abutmentsection B. It will be noticed that the inner faces of the hooks a and a are rounded at a2, so that they can rock slightly in connection with the parts they engage in order to permit a slight canting action of the bar during the initial creeping of the rail, so the hook a will be caused to ride along with the inclined outer surface b2 of the cu of the abutmentsection. It will be noticed that the hooks are comparatively narrow in the direction of length of the rail, so that this rocking and canting action will be effective in the operation of the invention.

The abutment-section B comprises the cuff portion b, adapted to embrace the edge1of the rail-base D opposite that engaged by the hook a, and the depending plate B at the larger end of the cuff b, said cuff being inclined on its outer edge at b2 and gradually widening toward the plate B', which latter is arranged to engage the tie C and is braced by a web B2, which tapers upwardly, as shown. The inclined or tapered surface b2 of the cuff is engaged by the hook a of the bar A, and during the initial creeping of the rail the cross-bar A will tighten by the engagement of the hook a/ with the cull and will operate to grip the base of the rail between the said cuff b and the hook a of the cross-bar, thus preventing the creeping of the rail in the direction of the tie.

It will be noticed that the cuff embraces the edge of the rail-base and forms a seat for said base at one edge of the latter, thus increasing the engagement between the cuff and the rail-base.

It may in some instances be preferred to tooth or roughen the cuill b on its inner and outer sides at b3 and b, as shown in Figs. l and 5, to increase the engagement of the cuff with the rail and of the hook a with the cuH.

In Figs. 2 and 3 I show the cross-bar made in sections adjustably connected at A3, so the bar may be adjusted as to length to suit different widths of rail-base. If desired, however, the bar may be made integral, as shown in Fig. 7.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. An anticreeping device substantially as herein described comprising an abutmentsection having a cuff provided with a plate to underlie the edge of a rail-base and with a top plate to overlie said base, the outer side of said cuff being inclined or tapered toward one end and provided at the larger end of said cuff with a depending plate to abut a crosstie, and a cross-piece provided at its ends with upturned hooks to engage the edge of a rail-base and the outer side o the cuff of the abutment-section, said hooks being comparatively narrow whereby they may cant or rock in the initial creeping movement of the rail, substantially as set forth.

2. An anticreeping device for railroad-rails comprising a cuff having plates overlying and underlying and adapted to receive between them the edge of a rail-base, and a cross-piece having means for engaging said cu and the opposite side of a rail-base, substantially as set forth.

IIO

3. The combination in a device for preventing rails from creeping, of a culi-section adapted to embrace the edge of a rail-base and tapered or inclined on its outer side, of a cross-bar having at one end a hook engaging the outer side of said cuff and adapted to rock in engagement therewith, means being provided at the opposite ends of the crossar for engagement with the rail-base and adapted to rock in its said engagement, substantially as set forth.

4. An anticreeping device comprising a cuil" adapted to embrace a rail-base and having its outer side inclined or tapered and means engaging with said inclined or tapered side for binding the cuff to a rail-base, substantially as set forth.

5. An anticreeping device consisting of an abutment section having a cuil provided with upper and lower plates to lit above and below the edge of a rail-base and a depending plate at one end of said cuff to engage with a cross-tie and a cross-bar hooked at its ends to engage with said cuff and the opposite edge of a rail-base to which said cud is fitted, substantially as set forth.

6. An anticreeping device comprising an abutment-section adapted to t one edge of a rail-base and a cross-bar provided at its opposite ends with upturned hooks rounded in the direction of length of the rail and adapted to engage with the outer side of the abutment-section and with the opposite edge of a rail-base and to rock or cant in the direction of length of said rail in the initial movement of a rail, substantially as set forth.

7. An anticreeping device comprising an abutment section to engage one edge of a rail-base and a cross-bar having at its ends upturned hooks to engage said abutmentsection and the opposite edge of a rail-base and made in sections adjustably connected whereby the said cross-bar may be adjusted as to length substantially as set forth.
