Application filed March 10, 1913. Serial llo. 753,268.

To all whom it may concern Be it known that I, PERCIVAL H. TRUMAN, a citizen of the United States, residing at Evanston, in the county of Cool; and State of Illinois, have invented certain new and useful Improvements in Ruil- Stays, of which the following is a specification.

My invention relates to rail stays some times termed rail anchors or anticreepers, and the invention has for its principal object to provide o novel device of this sort so constructed that the relatively movable parts "forming the clamp on the rail have a positive engagement one with 5 another when in operative position, which prevents the separation of these parts and hence the loosening of the clamp on the rail. A further obJect 15 to provide a ra1l stay comprising two clamping or rail engaging 0 members one of which is somewhat resilient so that the contraction of the rail due to change in temperature after the device is applied thereto will be taken up and therefore the integrity of the clamp preserved.

The invention has for a further object to provide a. device which will be light, strong and inexpensive to manufacture, and which, moreover, can be readily applied to the track in the places required.

In the drawings, the invention is illustrated in two preferred embodiments. It will be obvious that the same principle might be utilized in somewhat different constructions.

VVith reference to the drawings, Figure 1 hows a side elevation of a device embodying one form of the invention as applied to a rail, the rail being shown in cross section and the tie in elevation. Fig. 2 is a plan 40 view of the parts shown in Fig. 1; Fig. 3, a

sectional plan taken on line 3-3.o'f Fig. 1; Fi l, :1 view, in perspective, of the resilient wedge; Fig. 5, a. view, in perspective, of modified construction shown as applied to es the rail; Fig. 6, a plan view illustrating this construction; Fig. 7, a sectional plan thereof corresponding to the sectional plan shown n Fig.3; and Fig. 8, a. View, 1n perspective,

of the resilient member employed in the so construction shown in Figs. to 7 inclusive.

, Like charupters of reference designate parts in the several figures of the cirawings. in the drawings, A designates a. railroad, rail and B one of itssupporting ties.

Referring first to Fig.1 to e, inclusive,

the wedge therefore serves two purpo it serves to take up any looseness in the.

v. isionary member of the device and ens of which compn i I respectto the direction or said ,tiv nept.

the device shown therein consists of a. strap or yoke C, which is preferably, though not necessarily, made or malleable iron and is provided with a tie abuttingflange D, and of a hollow, resilient wedge or key E which may conveniently be made of sheet steel pressed into suitable form. The strap C is formed at one end with a jaw F which. en gages one edge of the rail base and at the other with a preferably larger jaw G. The 5 spring wedge E is driven in betwecn'the jaw G end the adjacent edge of the base of the rail. The preferred form oi wedge is best shown in Fig. l. It is pressed or formed so as to provide a lip H, extending under the rail base, and a double or folded lip I which overlaps the upper surface said rail base. The upper or outer surface of the wedge member and the inner sur" face of the jaw Gr are preferably provided with co-engaging' shoulders which prevent the wedge from backing out of its operative position. For example, the Wedge may be formed to this end with pressed out ribs 5 and the inner surface of the jaw with teeth K. It will be observed. that the we when driven into place, will yield so no allow the ribs J to pass over the teeth The wedge may be driven into the 5. 1 far as may be necessary. lhe resiliency of First, it allows the wedge to yield to nut its locking shoulders to puss the co-- gaging shoulders on the aw, and, second,

clamp resulting, for example, from the con traction of the rail base due to change temperature after the device is applied.

In Figs. 5 to 8 inclusive is shown another rail stay constructed on the same general. principle. The resilient wedge inc ber T in this construction, is provide abutting flange M and the strep M upon the wedge, the wedge the movable member.
