5 Claims.

My invention relates to railway track skates of the spring tail type, and has for an object the provision of means for preventing undue bending of the tail portion while occupied by the wheel of a car. More specifically, my present invention is an improvement on the skate shown in Letters Patent of the United States No. 1,851,347, granted to M. B. Cameron on March 29, 1932. 1

I will describe one form of skate embodying my invention, and will then point out the novel features thereof in claims.

The accompanying drawing is a view showing in side elevation, partly sectioned, one form of skate embodying my invention.

Referring to the drawing, the skate comprises a body portion A, the underside of which is provided with a longitudinal recess 4 to receive the head of a track rail R. This body portion is cut off at the point 2 to form a stub end from which the upper surface 3 curves upwardly to receive a car wheel. This upper surface is provided with a slight convex bulge at the point 8, to prevent a car wheel which is in place on the skate from rolling backwardly off the skate. The tread of a car wheel which'is in its final position on the skate is indicated by the line 9.

The skate also comprises a spring steel tail B, one end of which is attached to the upper surface of the stub end of the body portion A, and the other end of which rests on track rail R. The upper surface of the body portion A is preferably provided with a longitudinal recess 6 extending inwardly from the stub end 2 to accommodate the tail B, so that the upper surface of the tail lies flush with the upper surface of the body member A. As here shown, the tail B is attached to the body member A by rivets 5.

The tail B is provided with supporting means at an intermediate point. As here shown this means is a filler block C which is attached to the under surface of the tail B between the stub end 2 and the free end of the tail. This block may be of such thickness that it is normally spaced from the rail R, and as here shown, the

vertical thickness of the block Cis greater at the end nearer to the skate body portion than at the end nearer to the free end of the tail B, so that when the block C rests on the track rail R, the upper surface of this block will form an inclined plane. The block C may equally well be of such thickness as to rest normallyon the rail, and it may be formed as an integral part of the spring tail. Its effect may also be produced by suitable bends in the spring tail, and in short, my

invention contemplates any means for supporting the spring tail.

When a car wheel encounters the skate, it first rolls upwardly on the free end of the tail B, and in so doing it deflects the tail until the block C rests on the surface of the rail. The wheel then continues to roll upwardly on the inclined plane formed by the tail, until it finally reaches a point where it rides on the convex bulge 8 of the skate body. A slight further forward motion of the wheel results in a downward movement thereof, so that when it finally reaches the position indicated by the line 9, it will have no tendency to roll backwardly oif the skate.

In theabsence of the filler block C, and under certain adverse conditions, such as a wet or slippery rail, the friction of the skate on a rail may not be sufiicient to overcome the horizontal reaction which must be resisted in order to cause the wheel to be raised from the thin tail B to the thick section of the skate body at the stub end 2. By supporting the tail B at an intermediate point, this difiiculty is avoided and a car wheel will ride upwardly onto the skate under all reasonable conditions.

Although I have herein shown and described only one form of skate embodying my invention, it is understood that various changes and modifications may be made therein within the scope of the appended claims without departing from the spirit and scope of my invention.

Having thus described my invention, what I claim is:

l. A railway track skate comprising a body portion having a stub end, a spring steel tail having one end attached to the upper surface of the stub end of said body portion and its other end resting on the track rail, and a filler block attached to the under surface of said tail and normally spaced from the track rail for supporting the tail while a car wheel is rolling upwardly thereon.

2. A railway track skate comprising a body portion having a stub end, a spring steel tail having one end attached to the upper surface of the stub end of said body portion and its other end resting on the track rail, and a filler block attached to the under surface of said tail for supporting the tail while a car wheel is rolling upwardly thereon, the vertical thickness of said block being greater at the end nearer to the skate body than at the end adjacent the free end of the tail so that when the block rests on the track rail its upper surface forms an inclinedplane.

3. A railway track skate compr sing a body portion having a stub end and a slight convex bulge on its wheel engaging surface near the stub end to prevent a wheel from rolling backwardly off the skate, a thin spring steel tail having one end attached to the upper surface of the stub end of said body portion and its other end resting on the track rail, and supporting means located at an intermediate point on said tail to prevent undue bending of the tail while a car wheel is rolling upwardly thereon;

4. A railway track skate comprising a body portion having a stub end, a spring steel tail having one end attached to the upper surfaceof the stub end of said body portion and its other end resting on the track rail, and means located at an intermediate point on said tail for preventing undue bending of said tail while a car wheel is riding upwardly thereon.

5. A railway track skate comprising a body portion having a stub end, a spring steel tail having one end attached to the upper surface of the stub end of said body portion and its other end resting on thetrack rail, and a filler block attached to said tail at an intermediate point on the tail for supporting the tail from the track rail while a car wheel is riding upwardly on the tail.
