way tracks.

The object of my-invention is to provide a cheap, simple dnfl efiicient anti-creeping device for railsfwhichwill prevent the longitudinal creeping or travel of the, rails, as

well as one which can be easily and quickly applied to the rails, and will not be liable'to become loosened or removed'from the rails, but will always such rails. I

My invention consists, generally stated, in the novel arrangement, construction and combination of parts, 'as hereinafter more specifically set forth and described and .par-:

. ticularly pointed out in the claims.

To enable others skilled in the art to which my invention appertains to construct: and use my improved anti-creeping device for rails, I will describe the same more fully, referring to the accompanying drawing, in which- Figure 1 shows a cross-section of a railway rail having myimproved anti-creeping device applied thereto. Fig. 2 is a side elevation of the rail, showing my improved anti-creeping device in position and in section on theline 22 Fig. 1. Fig. 8 is a perspective view of one of the clamps employed. Fig. 4 is ajperspective view of the wedge employed.

Like symbols of reference herein indicate like/parts in each of the figures of the drawing.

As illustrated in the drawing, 1 represents the ordinary approved form of a railway rail having the usual rail base or flange 2 at the bottom of the same, and 3 myimproved anti-creeping device, which comprises the two

clamps

4 and 4 having the curved or inwardly turned outer ends 5 thereon for fitting around and embracing form a binding action with v Specification of Letters Patent. Pat ted Jam--18, 1910. Application fileil August27, 1909. Serial No; $4,879.

inclined faces 7 extending inwardly and: up-

wurdly from the faces 6 and on the same line as the upper inclined faces 2 on said rail flange for engaging therewith. The clamps 4 and 4' are detacha j and loosely connected together centrally under the rail base 2 by a hinged joint 9 when the said clamps are in position on the said rail flange. The joint 9 is formed by the

inner ends

8 and 8 on the

damps

4 and 4 respectively. theinher-fend -8 havingia downwardly extending lip 101at its outer edge, and the inner end 8 havingan upwardly.extending lip 10' at its outer" edgeand such li ps "l0 and 10' are adapted to bear against each other by their engaging faces 1Q.', while such lip 10' will also fit within a curved seat 11 formed in the end 8' by it'scu'rved outer'dge' 12. and thereby form an interlockin hinged joint.

Thebedy portions 4 on the clamps 4 and 4' are each provided on their inner side faces 13 with a'tapered portiorf' 14, which extends longitudinally of said clamps and parallel with the rail base 2,- and the side edges 14 of the grooves forming such tapered portions are preferablv converging towwd each other.

A wedge 15 is employed with the

clamps

4 and 4 which has preferably longitudinally-converging side edges 16, and in the same direction and line as the side'edges 14' on the tapered grooves 14, and such wedge has also the transversely-converging inclines l7 and 17"on each side of the same.

WVhen it is desired to secure the

clamps

4 and 4 on the rail flange 2, such clam s are connected togeth'enby the hinged joint 9 and the endsf5 on such clamps are engaged with and embrace such railtlange, so that the wedge 15 canbe inserted between the bottom of such rail flange and the inner faces 13 of the clamps, which will allow such wedge to be seated inthe tapered ,portion 14 on said clamps. llhen the wedge 15 is thus inserted the converging

inclines

17 and 17 thereom by thus engaging with the tapered portion 14 cant or tilt the.

clamps

4 and 4 on their hinged joint 9 and thereby form two

converging inclines

18 and 18 on such tapered portions, which dip toward the center of said joint, andi such inclines on said clamps are on a less angle or incline than their engaging inclines on said wedge, so that the central or deepest portion-17 on said wedge and between the

inclines

17 and 17 engages with

such inclines

18 and 18, at the hingedjoint, as indicated at a, to free the outer side edges on said inclines 17 andl? from the in-- clines 18 and 18f and form the spaces bat these points, as shown in Fig. -1. p 'lhe wedge 15 is provided with a depending head,15 at the broad endof the same, which is-adapted for engagement with the tie c, as shown in Fig.2, or with any other stationary .part of the track or road-bed, and 'when the device is in position on the track, as previously described, such end of the wedge is in the direction toward which the rail a is liable. to creep and which is indicated by the arrow d on said rail in Fig. 2. When thedevice'is thus in position on the rail 1, it will be found that by reason of thelongitudinal or by the longitudinal and transve'rse inclines l8 and 18 on the clamps 1- and' t', the said clamps will be tightly wedged on the said rail through the wedge 15 being engaged'by a stationary object, such as the tie '0, and any shocks, stresses or ressure in the direction of the arrow at wilserve to tighten the grip of the clamps on account of said...wedge not being able to move in such direction.

It will 'thusbe seen that in the use of my improved anti-creeping device for rails, the'moi'e thetendency of the rail to creep the tighter the wedge is inserted in the clamps, so that such clamps will be thus further tilted or canted and have a greater friction between the 'rail base, wedge and clamps and between the wedge and the clamps,- while the. outer ends in the clamps will have a more binding or gripping action on the rail base, so that such ends will not only more firmly. bind or grip the upper surface of such rail base, but will also have the same action on the outer edges of said base; In this wedging action and upon such further tilting orcanting of the clamps,

, the wedge will also have a greater wedging on the inclined surfaces ofsuch clamps and,- centrally of the clamps,'which will produce tensile stresses in the clamps, rather than a bending stress in the'same at the points I; and increase the friction on the upper and side edges of the rail'base by said clamps. It will also be seen that in the use of my improved anti-creeper for rails, the dangerous creeping of the rails, the breaking of the bolts" or spi es at the joints and the disloca-' tion cities and road-bed are thus prevented, or very'much guarded agalnst, and much' more efiectively than in the usual and ordinary track construction.

The device can be quickly. and readily applied to the rails bylreasonv of detachable and interlocking parts without disturbing such rails or the track construction, and without'interfering with or interrupting the traffic on such rails.

Various modifications and changes in the design and construction of the various parts of my improved anti-creeping device for railsmay be resorted to without'departing from the spirit of the invention or sacrificing any of its advantages.
