RAILWAY-RAIL STAY.

SPECIFICATION forming part of Letters Patent No. 779,086, dated January 3, 1905.

i Application lled May 2, 1904. Serial No. 205,891.

To all whom t may concern:

Be it known that we, EDWARD LAAs, of Elgin, in the county of Kane, and HIEAM I-I. SPONEN- BURG, of Wadsworth, in the county of Lake, in the State of Illinois, have invented new and useful Improvements in Railway-Rail Stays,`

.. or creeping longitudinally on its supporting cross-tie; and to that end our invention oonsists in the improved construction and combination of the rail-gripping jaw and its seat upon the bracket or bar which abuts on the side of the cross-tie, all as hereinafter more fully described.

In the annexed drawings, constituting part of this application, Figure 1 is a transverse section of a railway-rail equipped with our improved rail-stay. Fig. 2 is a plan view of the same. Fig. 3 is a transverse section on the line X X in Fig. 2; and Fig. I is an enlarged horizontal sectional view of the railgripping jaw and adjacent portion of the rail, taken on the line Y Y in Fig. 1.

R represents the rail, which is supported on the cross-tie O in the usual manner.

The arrow N in Fig. 2 indicates the direction in which the rail tends to creep.

c designates the bracket or bar, which extends across the under side of the rail R and is formed with a hook or jaw which grips one of the flanges of the rail. The opposite end of the bar c has adjustably secured to it the jaw c, which grips the adjacent iiange of the rail.

Our present invention resides in the construction of the jaw o and the means for sustaining the said jaw on the bracket or bar c. This jaw we form with a rail-gripping face d, which is serrated, so as to provide it with iine teeth which bite into the edge of the rail-base and obtain a secure hold thereon, as illustrated in Fig. 4 of the drawings. Above the serrated gripping-face cl is alip l, projecting from the jaw and bearing on the top of the railflange.

To thoroughly brace the jaw c and increase its efficiency, we form the bar or bracket c withan'upwardly-projecting shoulder e, on

which the back of the jaw c abuts. The central portion or' this shoulder e we form with a longitudinal segmental facef, preferably concave or of the form of a recess and with straight end faces ff, as shown in Fig. 4t of the drawings. The back of the jaw c is formed correspondingly and abuts on the aforesaid faces of the shoulder c.

The jaw c is provided with a vertical aperture L, which is in line with an aperture /L in the bracket a, and through the said apertures passes the bolt c', which is provided with a head j' on one end and with a nut a on the opposite end and firmly clamps the jaw on the bracket a.

- 0 denotes a vertical flange which is formed on the bracket a and bears on the side of the cross-tie O to prevent the rail from creeping endwise. A rib 0', formed on the bracket and on the flange 0, serves to brace the said ange.

By leaving a slight space t between one of the end faces f and back of the jaw the jaw is allowed to slightly turn, and thereby cause the jaw to more iirmly grip the rail when subjected to longitudinal strain.

What We claim as our invention is l. In combination with the rail and crosstie, a bracket abutting on the side ofthe crosstie and provided at one end With a rail-gripping jaw and at the opposite end with an upwardly-projecting shoulder formed with a longitudinal segmental central portion in its face and with straight end portions on said ping face and With an outer face conformed to and engaging the aforesald shoulder as set forth.
