Specification. of Letters retest.

1/ '0 all whom "it may concern:

Be it known that I, EDWARD Less, at citi- Zcn of the United States, residing at Chiago, in the county oi: Cook and. State of l'llinois, have invented certain new and useful Improvements in Anticreepers, of which the following is a specification.

My invention relates to an onti-crecper for railroads, and one of the princi objccts of the invention is to provide a novel and improved device for preventing the iongitudinsl creep of railroad rails which will be light in weight, inexpensive to manufacture, strong enough to withstand the stresses to which devices of this class are subjected, and which will take it iirni and the rail as against the varii'eliahle hold on ous influences, such as the 'ibretion of the rail and the contraction and expansion theretion.

tending to loosen the frictional grip of the device on the rail base and thereby make it ineffective to resist the creep of the rail. in this connection my invention employs spring nielnber extending under the rail which is drawn up against the rail end thereby bent by means of a locking Wedge, the bending of the spring causing it to exert a constentstress which aids maintaining the grip of the device upon the rail base.

The invention consists in the constructions end arrangements, to be hereinafter described and claimed, for carrying out the above stated objects and such subsidiary objects is will appear from the following specification.

The invention is illustrated, in certain preferred embodiments, in the accompany-. ing drawings wherein- Figure 1 iso view, in perspective, of one form of the invention, the device being; shown as applied to a rail. Fig. is a side elevation of the device illustrating the manner in which it is applied to the rail. Fig; 3 is fragmentary cross sectional view through the wedge end of the device and adjacent portion of the base flange of the rail. l in'. ,4 a view. in perspective, of the yoke member of the device. Fifi. is a. view, similar to Fig. 2, illustrating a. modified construction. Fig. 6 is {L fragmentary sectional view taken on. line 6-4) of 5, and Fig. 7 a view, in perspective, of the yoke member in the modified form of the invention 3, A portion of the projection 13 Lil's characters of reference designate like parts in the several figures of the drawings. Referring first to Figs. 1. to I} inclusive, A desig nates a. railroad rail having; a base 3 flange B, and C- 15 one of the ties on which the rail supported. The device oi my invention is shown bootl g; against the tie C and the portion the which. lies against the tie is referred to the tie abutting member. it will be 1 that the device i'n'ight abut an, met any other fixed element of the rondhed.

The device shown in the first three figureu of the drawings consists ot a yoke member 10 and wedge ll. The yoke member consists, as shown, of a Hat bar of steel having certain amount 0% resiliency which is formed at one end with a hoot: or l2 and at the other end with an upstanding projecis a supporting The wedge severed and bent out to form plate l-l for the wedge 11. preferably formed on its uppe. surface with a plurality of serrations 15. The yoke is given a bend or permanent set so tl'iat when the jaw lQengeges the edge of the base flange B the other end of the device stands a trifle below the opposite edge of the hose flange, as indicated in the dotted lines in Fig. 2. The wedge ll is driven into the opening 16 in the projection 13 and bears upon the supporting plate 1 and the upper inclined surface of the base flange. By driving the wedge in,

the end of the yoke member is drawn up against the bottom of the base flange so that it exerts a. constant spring pressure against the .wedge. This draws the corner 17 of the projection 13 down upon the serrations 15 on the top of the wed e -ellectually preventing the backing out of the wedge which might otherwise be caused by the vibration of the rail or other disturbing influences. The wedge may be driven in as "far necessary in order t give the device a firm and reliable hold on the rail. it will be seen that this device may be applied to rails which differ at trifle in their dimensions. Railroad rails supposedly the some size frequently difl'er slightly because of the wear on the rolls by wl'iich they are produced. The initial hold of the device on the rail is increased in case the rail starts to creep. This is accomplished. by provid ing one end of the yoke, preferably the end adjacent 12, with n tie abutting flange zed, however,

18. The other end of the device, the wedge end, stands out of contact with the tie so that the tendency of the rail to creep gives the device a diagonal set'by which such tendency is immediately checked. However, it is essential, in order that this clamping action should take place, that the initial frictional hold of the device on the rail base should be sufiicient to prevent the rail from slipping through'the device. -In this connection my invention provides for a clamping hold of the device tn the rail formed, in the same general way, of a fat. piece of steel bent up at one end to form jaw 20 and at the other end to 'form an .upstanding projection 21. The supporting plate 22 for the wedge is formed with depending flanges 23 so that it is channelshaped. The flanges bear against the body portion of the yoke. By this arrangement the support-for the wedge is considerably strengthened. Similarly the tie abutting member 24- is formed with wings or flanges 25 which extend under and bear against the lower side of the body portion. of the yoke.

It often happens that the edge of the tie is rounded oil, as indicated at 0 in Fig. 6, G designating the tie. Withthe face of the tie so shaped the thrust of the anti-creeper is against the lower portion of the tie abutting member. The wings 25 are to prevent the tie abutting memberfrom bending, under such circumstances as these.

While I have described my invention in certain preferred embodiments, it will be realized that modifications might .be made as to details of construction without departure from the principles of the invention. Therefore I do not wish to be understood as limiting the invention to the precise constructions, arrangements and devices shown and described except so far as such limita I tions are expressed, in the claims.
