ANTICREEPER RAIL PLATE.

Application filed February 23,1924. Serial 110.694,?49.

To all whom it may come-m:

Be it known that I, Burns M. LovnLAoE, a citizen of the United States, residing at Crowder, in the county of Pittsb-urg and State of Oklahoma, have invented certain new and useful Improvements in Anticreeper Rail Plates, of which the following isa specification.

This invention relates to anti-creeper rail plates and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide a plate of simple form adapted to be applied to the tie and rail of a railway track structure and which will prevent. the rail from slipping or running longitudinally over the tie toward low places in the road bed.

The fact is well known that unless means are provided for restraining track rails against creeping, they move longitudinally under the influence of the traflic passing over them or they slide down inclined stretches of the road, and the sections tend to crowd or accumulate at low places and in extremely warm weather, the sections of the rails eX- pand longitudinally and some of the sections are liable to kink or bow whereby they are thrown out of true alinement and such distortion frequently results in accident due to derailment of the rolling stock.

Therefore it is the object of the present. invention to provide simple means, such as stated, to prevent the rail sections from creeping and to positively confine them in their proper and prescribed relation with respect to each other, with respect to the ties, and with respect to the road bed.

In the accompanying drawing:

Figure 1 is a fragmentary plan view of a track rail showing the anti-creeper plate applied thereto.

Figure 2 is an edge elevation of the anticreeper plate.

Figure 3 is an enlarged fragmentary end elevation of the anti-creeper plate viewing the same at the opposite end from that end which is shown in Figure 2.

The anti-creeping rail plate comprises a body portion 1 which is prefer-ably rectangular in plan and which is provided at one Side portion with a curved lip 2 which extends the full transverse breadth of said body. The body portion 1 is provided in the vicinity of one corner thereof and at a t and the lug 5are located with aprong portion 6. The end portion ofthe prong 6 is sheared off diagonally whereby a vertical edge 7' is provided at the end of the said prong, the said edge 7 being in alinement with the ajacent side edge of the body 1.

The prong 6 is also-provided at its underside with relatively sharp edges 8 and 9 which converge toward the edge 7 and which are adapted to bite into the upper surface of thebase flange of-the rail when the anticreeping plate is applied. The rail is indicated at 10. The inner edge surface of the hp 2 is cut away at 11 at one end of the said lip in order that the body 1 of the plate may assume the position with relation to the rail as indicated in dotted lines in Figure 1 of the drawing when the plate is being applied to the rail. .To apply'the plate to a rail, the same is first turned to an angle with respect to the rail, as indicated by the dotted line and slightly tilted with respect to the plane of the base flange of said rail, so that the lip 2 may be inserted over the base flange of the rail at one side, following which the prong 6 is moved upwardly beyond the base flange, at the other side of slateorrlcs. Y

the rail, the plate still retaining an inclined relation with respect to the base flange of the rail, due to the contact of the lug 5 with the bottoin'thereof. The inclination of the lip 2 is sulficient to permit a substantial amount of play between the base flange of the rail and the lip, to allow the plate to be positioned in "inclined relation under the bottomof the rail during its turning movement, in order to move the lug 5, which is relatively small in height, past the edge of the base flange of the rail into the full line position of Figure 1. tial application of the plate, the same is rotated to the transverse position, shown in Following this parp and prevent creeping thereon.

full lines in Figure 1, from the dotted line position, in order that the lug 5 may be moved outwardly beyond the side edge of the base flange of the rail, in order to move the plate upwardly so that the base of the plate contacts with the base of the rail, following which the same is ready for spikin to the tie. When the plate 1s positione as illustrated in full lines, in Figure 1, spikes may be driven through the openings 3 and 4, so that the plate is fastened to a tie and held in locked relation, in connection with the rail, the lip 2 and prong 6, in this relation, firmly engaging the face of the base flange of the rail, and serving in cooperation With.

the spikes driven through the openings 3 and 4:, to retain the rail relative to the tie, Thus when the spikes are driven and the plate is applied to the rail as indicated, the rail is positively held against longitudinal movement with relation to the tie thus preventing creeping and the objectionable features in cident thereto.

intense Having described the invention, What is claimed is:

an anti-creeping rail plate comprising a body having at one side portion a lip ex tending from edge to edge of the body and provided at one end with an inner cut away wall portion, spike openings passing through the body and located in the vicinity of diagonally opposite corners thereof, a lug formed upon the body at the side of one of the spike openings, a prong formed upon the body and having a pointed end disposed toward the opposite spike opening, the inner end of the prong being sheared diagonally whereby a vertically disposed sharp edge is provided at the extremity of the prong, said edge being located in the same plane as the adjacent edge of the body and the converging edges of the prong being sharpened at the lower face of the prong and adapted to cut into the base flange of a rail when a plate is applied.

In testimony whereof I afiix my signature.
