Application filed July .27,

To aZZ whom it may concern:

Be it known that 1, JOHN A. BonKIN, a citizen of the United States, and a resident of the borou h of Manhattan, in the city, county, and tate of New York, have invented certain new and useful Improvements in Rail Anchors, of which the following is a specification.

My invention relates to an improved rail anchor designed for the purpose of preventing creeping of railroad rails.

As well known, rails are held to the ties of the track by spikes which are driven into the ties with their heads overlapping the edge of the rail flange, the rails, of course, being spliced to each other at intervals. Difiiculty is experienced with such a construction with creeping of the rails which tends to force the ties out of place.

It is Well known that all rails creep more or less, and on double track roads where the traffic on one set of rails is continuously in one direction the creepage is more pronounced. The effect of creeping is manifested in numerous ways, as by bunched or slowed joint ties, locked switches, deranged crossings, and so forth. While creeping at the point of origin is almost imperceptible, yet as the creeping builds up the tracks will be deranged eventually at some point. The point of origin is where the train takes on speed and if the first rail is successfully held against creep it is an easy matter to prevent creeping of the other rails.

It is an object of my invention to provide a simple and inexpensive means for overcoming creeping by rigidly connecting a number of ties together, particularly at the rail joints, which enables me to obtain substantially maximum ballast resistance.

In general, my invention comprises a de vice so shaped as to be capable of being driven into two or more ties to rigidly secure the ties to each other, thereby obtaining the maximum ballast resistance, that is to say, resistance to movement of the ties in the ballast. This, of course, very materially decreases,-in fact substantially eliminates,rail creeping.

Briefly, my improved anchor comprises a U-shaped member, the legs of which are bent at an angle to the body portion there of and provided with cutting faces extending parallel to the body portion of the anchor. I have found in practice that by pro- 1921.. Serial no. 487,841.

track with several of my improved anchors applied thereto.

Referring to the drawings in detail and first of all to Fig. 1,it will be seen that my improved anchor comprises a body portion A and legs BB, these legs being'bent at an angle to the body portion so that the anchor as viewed in Fig. 1 may be said to be substantially U-shaped. The legs B-B are each provided with beveled faces C Which form a cutting edge and as will be seen from Fig. 1 are substantially parallel to the body portion A.

It will be understood, of course, that each leg B may be provided with one or two beveled faces C as desired.

In Fig. 2 D indicates rails which are spiked to ties E in the usual manner, the ties resting in the ballast F of the road bed. At G there is a joint in the rails and one of my anchors 4: has been driven into a tie at each side of this joint.

As will be seen from Fig. 2, the anchor is preferably also applied to other ties along the track and it is to be understood, of course, that the anchor may be made of any convenient length so as to span more than two ties if desired.

As above pointed out the beveled faces C are parallel or substantially parallel to the body portion A of the rail anchor so that when the rail anchor is driven into the ties checking or splitting of the ties is prevented.

From the foregoing it will be seen that I have provided an improved rail anchor adapted to be applied to two or more ties of a track to which the rails are secured, where by the ties to which the rail anchor is applied Will be rigidly secured to each other to offer an increased resistance to movement of the ties in the ballast of the road bed to thereby eliminate or substantially eliminate creeping of the rails.

While I have described a specific embodiment of my invention it is to be understood that changes may be made therein without departing from the spirit and scope of my invention ;for example, the rail anchor illustrated is substantially square in cross section whereas, as a matter of fact, it could just as well be round or halfround for example. Likewise, the legs B have been shown bent at substantially right angles to the body portion A whereas it comes within the scope of my invention to vary this angle as desired.

What is claimed as new is:

, A rail anchor comprising a body portion,
