RAIL-ANCHOR.

Patented Aug. 6, m8.

Continuation in part of application Serial No. 858,230, filed August 24, 1914. This application filed June 3,

' 1916. Serial No. 101,433.

simple in its construction, inexpensive to manufacture, light in weight, strong and capable of taking a firm and reliable hold on the rail, which will not be disturbed by vibration or other causes tending to loosen' the grip of rail anchors on the rails engaged thereb A further object is to provide a device which may be quickly and conveniently applied to or disengaged from the rail.

The invention is illustrated in two typical embodiments. In one of these embodiments the device is composed of two elements, one of which may be termed a railgripping orengaging element, and the other a tie-engaging element. The tie-engaging element bears against the side face of a tie or other stationary part of the roadbed and has a wedging relation with the rail and rail-engaging element. Inasmuch as my invention contemplates making and constructing the rail-engaging element so that its hold on the rail is not entirely dependent upon the wedging relation with the other element ust mentioned, it is possible to omit the separate tie-engaging member entirely,

in which case the rail-engaging element bears immediately against the tie. The second embodiment of the invention consists, therefore, of a one-piece rail anchor or anti-creeper so constructed that when applied to the rail it willtake a hold upon the same sufficient, when the device isabutted against a tie, to check the tendency of the rail to creep.

In the drawings Figure 1 is a longitudi- I nal, sectional view taken through the twopiece device, which is shown as applied -to a rail and abutted against one of the crossties upon which the rail is supported.

Fig. 4 is a view in perspective of the tieabutting or wedge member of the two-piece rail anchor.

Fig. 5 is a similar view of the rail-engaging member.

Fig. 6 is a plan view with the web of the rail in section, illustrating the use of the rail-engaging member as a one-piece anchor.

Fig. 7 is a view of the device illustrating its application to the rail, and

Fig. 8 a view similar to Fig. 7, with the device in operative position.

Like characters of reference indicate like parts in the several figures of the drawings.

Referring first to Figs. 1 to 5 inclusive,

the tie-abutting member A consists of a flat piece of metal, preferably steel, having pressed therein, preferably, a tapering rib 10. One end of the piece of metal is bent over to form a tie-abutting plate or foot 11. The other is bent up as indicated at 12.

The rail-engaging member B consists of a bar of metal, preferably steel, with one end bent over to form a jaw 13, and the other end bentto form a somewhat longer jaw 14. The bar, which is generally bowed in its configuration, is bent somewhat sharply to provide an upward projection 15. This'projection-is preferably at a point ad= jacent the jaw 14. At about the middle of the bar another bend 16 is formed providing a hollow or recess 17 in the upper surface of the bar. The extremity ofthe bar forming the jaw 14 is preferably off-set so as to provide a shoulder 18. The other jaw 13 is provided on opposite sides with recesses 19 shaped to take the claw of a claw bar. The inner face of jaw 13 is preferably beveled off as shown at 20.

The application of the device to the rail, shown in the drawings at C,is as follows: The jaw 14 of the rail-engaging member B is hooked over one edge of the base flange of rail C and the tie-abutting wedge memher A is placed between the base flange and ting plate 11 against tie D. Fig. 2 shows the arrangement ofthe parts. The other end of the rail-engaging member B is then raised, for example, by means of a claw bar E and the device is forced or driven endwise, bringing jaw 13 into engagement with the edge'of the base flange of the rail adjacent thereto. The jaw, it will be seen, en-

gages both the upper and lower surfaces of the rail base. I contemplate a close fit of jaw 13 on the edge of the rail base. The movement of the rail-engaging member transversely of the rail causes the edge of the rail engaged by jaw 14 to seat behind the shoulder formed on the undersurface of the jaw. At the same time the rib 10 on the tie-abutting member is'engaged by the groove or recess 17 in the upper surface of the rail-engaging member. The application of the device to the rail is facilitated by-the beveled surface 20 on jaw 13 which comes against the upper edge of the rail base on this side of the rail.

The application ofthe device to the rail involves, in the first place, the bending of the tie-abutting member. This produces a stress between the device and the rail which is enhanced by 'any tendency on the part of the. rail to creep, .due to the fact that the tie-abutting member, because of the taper of rib 10, is in effect a wedge. In the second place, the rail-engaging member itself is subject to' a bending strain when applied to the rail. The jaws 13 and 14 are in effect obliquely disposed in respect to each other, the jaw 14 having a downward inclination with respect to the jaw. 13, which is substantially horizontal when the device is in its operative position. In other'words, the rail-engaging member when applied to the rail is deformed slightly at opposite sides of itsbearing point 15 on the bottom of the rail base. This deformation and consequent binding action of the rail-engaging member on the rail is quite independent of the tie-engagingmember, the effect of the latter being simply to enhance the grip of the rail-engaging member on the rail. It is, therefore, possible to eliminate the tie-abutting element and use the rail-engaging element alone to form a one-piece anti-creeper,

as shown in Figs. 6 to 8 inclusive. The railengaging member in such case lies flatwise against the tie and depends for its hold on the rail on the bending strain tov which it is subjected in being applied thereto.

vIt will be seen that a rail anchor constructed as shown, whether it be a two-piece deviceor a one-piece device, has a resilient hold on the rail which is not loosened by vibration or likelyv to be affected by other accidental disturbances. The effectiveness of the hold on the rail is not dependent upon bolts or upon wedge action, although the wedging relationship between the parts of "the device in the two-part anchor acts to injaw '13 and the other edge abutting on shoulder 18 formed on the other jaw, there is no chance for the rail-engaging member to be displaced transversely of the rail, particu-' larlyas anysuch disturbance of the device from its normal position is resisted by the bending stress constantly exerted against it. When the element B is used alone as a onepiece anchor it will be seen that the pressure of the device against the tie taking place when the creeping stress is exerted on the rail tends to tighten thehold of the device on the rail so that the creeping tendency isself checked.

This application is a continuation in part of 'my co-pending application Serial No. 858,230, filed August '24, 1914, (patented February 27, 1917, No. 1,217,541,) the form of the invention shown in Figs. 1 to 4, inclusive, herein being shown in F igs. 6, 7, 8 and 9 of the earlier application.
