BAIL ANCHOR.

Ap'plitationfiled March 28, 1921-.

To all whom it may concern Be it known thatI, RoLANnIs A. BLAIR, a citizen of the United States, residing at Fort Wayne, in the county of Allen and State of Indiana, have invented certain new and useful Improvements in Rail Anchors, of which the following is a specification.

My invention relates to a rail anchor or anticreeper, and a primary object of the invention is to provide a device of this type which will be light, strong, compact, economical to manufacture and so constructed as to have great holding power against the tendency of the rail to creep. I

A further object is to provide a rail anchor of-novel construction which can be used on. rails of different sizes and having rail bases of different configuration.

A further object is to provide a rail anchor which, in addition-to the characteristics referred to above, will'take a positive hold on the rail that is not dependent upon the creeping stress of the rail so that, if the device is provided with an abutment, it will hold the rail against longitudinal movement in either direction.

A. further object is to so construct the rail anchor that it may be removed and replaced repeatedly without impairing its holding power.

The invention consists of the new and improved constructions, arrangements, a-nd devices to be hereinafterdescribed and claimed for carrying out the above stated. objects and such other incidental objects as will be referred to in the accompanying description.

The invention is illustrated, in certain preferred embodiments, in the-accompanying drawings, wherein Fig. 1 is a plan view of one form of rail anchor made in accordance with my. invention, the anchor being shownas applied to a rail.

Fig. 2 is a sectionalview on line 2-2 of Fig.v 3 is a fragmentary view, in perspective, of the yoke member of the anchor.

Fig. 4 is a view, similar to Fig. 1, showing a modification.

Fig. 5 is a fragmentary View, similar to Fig. 2, showing another modification.

Fig. 6 is a detail view, in side elevation, illustrating the form of key employed in the anchor illustrated in Fig. 5, and

Serial No. 456,396

Fig. 7 is a View illustrating a different form of key.

Like characters of reference designate like parts in the several figures of the drawings. Referringfirst to Figs. 1, 2, and 3, 1O designates a railway railand 11 one of the ties supporting the rail. The rail anchor, as shown in these figures, consists of a yoke member 12' and a key 13, the latter being preferably tapered or wedge-shaped. The yoke 12 is'made, preferably, of a relatively high carbon steel so as to be resilient. It may be formed by cutting and bending a piece or blank of sheet steel. The yoke member consists of a bar 14 to extend under the base 15 of rail 10, a foot or tie abutting flange 16, andhooks or

jaw forming portions

17 and 18 made by bendingover the endsof the bar 14. The lipof jaw 18 is longer than that of jaw 17. The jaws are formed with

openings

19 and 20 for the key 13 which, as shown in Fig. 2, is driven through

openings

19 and 20 between the bottom of rail base 15 and the bar 14C of the yoke member. The key 13 is'preferably made of relatively soft steel so as to be tough and unbreakable, but this is not essential. The

openings

19 and 20 are preferably arranged in a diagonal line so that the key 13 stands obliquely to the rail. The purpose of this is to check the tendency of the yoke to rock on the key.

The

jaws

17 and 18 are preferably formed so that they are bent when the key" 13 is driven home. The dotted lines in Fig. 2 indicate, approximately, the original contour of the aws, the full lines showing the strained contour thereof when the yoke is under the wedging pressure of the key.

In Fig. 1 I haveshown a rail anchor like that shown in the precedingthree figures except that the openings 19 20 are disposed so thatthe keyis parallel to the tie.

In Figs. 5 and 6 the yoke 12 may, be formed either like. the yoke 12 of Figs. land 2 or the yoke 12 of Fig. 4:. The key. 13 is given a twisting set, the key, in this case being of relatively high carbon steel. When the key is driven in between the rail base and the yoke the twist is straightened to a greater or less extent, creating a strain which makes the key self-locking.

A similar-resu-ltmay be obtained bygiving the key a bend as shown in Fig. 7 the key in this figure being designated 13.

It will be seen that the holding power of a rail anchor constructed as above described will be very great in proportion to its size and weight. The device has a resilient en gagement with the rail so that its hold thereon is not easily afiected by vibration or other disturbing influences. The key has a very gradual taper with consequently little ten dency to back out from the position to which it is driven. The lips of

jaws

17, 18 are strained when the wedge is driven home. The device is easily applied to a rail by first hooking the jaw 18 over the rail base, raising the yoke and moving it laterally (to the left, Fig. 2) until jaw 17 is engaged with the other edge of the rail base, then driving in the key 13 (or 13 or 13, as the case may be). The device is as easily removed from the rail by driving the key from its small end. The anchor may be used repeatedly without detrimentally affecting its holding power. The same anchor may be used on rails of different sizes and somewhat different cross sectional configurations. For rails beyond the limit of adjustment of any given key the device may be adapted without change in the yoke by merely using a wider or narrower key. The yoke stands at some distance below the bottom of the rail base, particularly at the right hand end (Fig. 2) so that the tie abutting flange 16 does not have to be very long in order to obtain a firm bearing on the tie even when the latter is of the hewn type. Assuming an abutment for the flange 16 on both sides thereof, for example, when imbedded in the ballast the anchor will prevent rail creep in either direction.

I do not claim specifically herein the form of the invention illustrated in Fig. 7 of the drawings. The specific features of this form of the invention are described and claimed in my copending application Serial No. 544,494, filed March 17, 1922.
