RAILWAY RAIL STAY.

Specification of Letters Patent.

Application filed April 4, 1910. Serial No. 553,200

PatentedAug. 1t, 1911,

To all whom itmay concern:

Be it known that I, lmmr \V. Moons, a citizen of the United States, residing, at Evanston, in thecountv; of (look and State of Illinois, have invented certain new and useful Improvements in Railway-Rail Stays, of which the following is a specification.

The present invention relates to a stay adapted to be clamped to a rail and cooperate with the rail ties to prevent the creeping of the raiL'such as is evidenced at the terminus of a grade or the juncture of a switch, and] similar places where a weight is brought tobear on the rail, tending to force it to creep or move alon; the ties.

The objects of the. present; invention are. to form the portions of the stay so that. it will operate with a skewing movement to impinge itself against the rail; and to eliminate all superfluous and unnecessary metal from the stay without impairing in any way its etlieicncy in preventing creeping.

In the drawings, Figure 1 is a perspective view of the assembled stay; Fig. 2. a front view showing: the stay clamping a rail; Fig. 2), a section on line 3-3 of Fig. 2, looking in the direction of the arrow; and F ig. 4, a side elevation of the. assembled stay.

The stay, as shown, consists of two parts, 4 and 5. The part 4, for the sake of convenience, will be hereafter spoken of as the fixed member, although in usage. it is subjected to a slight turning, owing to the there- .to to clamp itto the rail; and the part 5 will be termed the movable section.

The fixed section at comprises a body portion 6, provided 'witha rail 'grippmgqaw 7 and with a downwardly depending. abutment 8, which in userestsagainst the tie. is of concave formation from its'center outwardly, and

theparticular function of this concave surface will be more fully broughtout herein-. after in the specification.

As shown in Figs. 1 and 3, each of the side walls of the fixed section has a. portion as indicated an 9. This rail gri ing jawv 7 of an abbreviatednw ture; but, as will hereinafter be shown, no great strain is placed upon this aw, so that the reduction thereof will not in any way affect the durabilityor etlectiveness of tne device. The fixed section is providedv with a curvedrecess 10, and the movable section o 1s provided with a curved depending portion 11, which 1s adapted to enter into said recess; said recess beingnndercuton one side to interlock with the depending portion 11, but, as will be seen by a studyof l jig. 3, the recess 1.0 and the'depending' portion 11 are on arcs struck from different centers, so that when the movable section is driven into position, the depending portion will contact the'walls of the slot, as indi' cated at- 12. in Fig. 3, thns'locking the two sections together. And any further strain placed upon the movable member will tend to rock the stay member about the abutment 8, thus swinging the rail gripping puts into tighter engagementwith the rail. Themovable section. as shown, is formed with a protruding surface '13, which forms a striking head against which the hammer or other instrument 'stzrikes when the stay is being assembled in position, and a rail grip ping' jaw 14.

As heretofore stated, theabutment 8 of the fixed member is of concave formation from its center outwardly, and the creeping of the rail will be resisted by the contacting" of this abutment against, the tie; hence,

when the strain incident with the attempted creeping of the rail is placed on the abutment, it will tend to rock the abutment about its rounded surface, so that a twisting or skewing movement will be imparted to the fixed section as a result of the pres sure of the rail on the abutment. This rocking movement Will twist or skew the fixed section so as to bring the rail gripping surfaces into tighter impingement against the rail, thus securely locking them thereto and causing them to travel with the rail during its crcepin movements,'and, as deseribed, this creeping movement will be resistedby. the abutment contacting the tie. Hence, the greater the strain placed on the abutment, the tighter the stay rail, had thus the movement of the rai will serve to bring the stay in tighter engagement; therewith, and the force incidentto the creeping of the rail will be utilizedto prevent such creeping, so that the greater the tendency of the rail to creep, the greater will will gri the be the resistance ofi'ered to such creeping,

-the abutment 8 in contact with the tie and driving the movable section into place until the dependin portion thereof has engaged the walls of t e groove in the-fixed portion and locked the two sections together. Then, when a pressure is exerted upon the stay, by

reason of the attempted creeping of the rail,-

such pressure will-be resisted by the abutment contacting the tie, and, at the same time, the pressure will tend to rock the abutment on the tie so that the rail gripping jaw of the fixed section will be skewed or twisted to more tightly impinge against the rail.

I claim: r 1. In a railway rail stay, the combination of a fixed clamping member and a movable.

clamping member, a rail gripping jaw on one side of the fixed clamping member, having a curved slot extending across the upper surface thereof from front to. rear and lying when the stay is in operative position on tirely beneath the flange of the rail, the movable clamping member having a downwardly curved portion extending along one edge thereof and ada ted to enter the curved slot in the fixed mem er,'the advancement of the depending portion 'in the recess serving to lock the two sections together, the 'iippe'r surfaces of the fixed and movable members lying flush with one another when the sections are assembled and bearing against the under surface of the rail, arail grippingj aw upon the movable section oppositely disposed from the aw on the fixed section when the sections are assembled, a rounded abutting portion on the fixed section adapted to bear against the tie, the creeping of the rail tending to rock the fixed section about the abutment, whereby a skewing movement is imparted to the stay, bringing the gripping jaws into tighter engagement with the flanges of the rail, substantially as described.

2. In a railway rail stay, the combination of a fixed clamping member and a movable the walls of the depending portion being struck with different radii, whereby the walls ofthe depending portion engage the Walls of the slot, when movement between the clamping members is effected, and lock the clamping members together, a rail gripping jaw on the movable clamping member, a rounded abutting portion on the fixed clamping member adapted to bear against a tie, the creeping of the rail tending to rock the fixed clamping member about the abutment, whereby the rail gripping jaws are thrown into tight engagement with the flanges of the rail, substantially as described,
