ANTICREEPING DEVICE FOR RAILS.

Specification of Letters B atant.

Patented Mar. 21, 1911.

Application filed March 10, 1910. Serial No. 548,332.

To all whom it may concern.

Be it known that l, EDGAR M. SMITH, a resident of New York, in the county of New York and State of New York, have invented certain newand useful Improvements in Anticreeping Devices for Rails; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 1

The primary object of this invention is to provide an anti-rail-creeping device Which may be made of sheet metal, and a further lffiobject is to so form such device as to allow for. a certain resiliency in the track rails so as to absorb shocks and lessen track noises.

The invention will be hereinafter fully set forth and particularly pointed out in the claims.

Inthe accompanying drawings, Figure l is an elevation, showing the Wedge in section. Fig. 2 is a plan View. Fig. 3 shoivs a slight modification. Fig. t shows a portion of a track rail equipped with my i1nprovement,

' Referring to the drawings, 1 designates a fastener platewhich is preferably made of sheet steel. In this plate, near one end, is a hole 2 to. accommodate a screw spike 3 which permitsthe plate to swivel on a center and thus automatically tighten its hold on the mil base to prevent creeping. The plate at its other end is formed with a lip l which is preferably produced by bending the metal back upon itself, and the inner face of this overhanging lip is inclined, that is to say, it is at ..an-angle to the vertical plane of the rail so that's. Wedge 5 driven between the base of the rail and the lip will. firmly bind the parts together. rail tends to turn the plate on its pivot, and this in turn autouuitically tightens the grip of the wedge on the rail. While I prefer to:

make the plate of sheet metal, it may be made of malleable iron.

I prefer to raise or thicken the base plate at itspivotedcnd, as shown at 6-, Fig. 1; at least i" prefcr to thus form alternate plates Any creeping of the so as to allow for a certain amount of re siliency in the track, the remaining portion of this plate being out of contact with the sleeper is free to give to a certain extent. This absorbs shocks and enables the track to be made comparativel. noiseless.

In practice, I usual y provide/for bending the reduced end of the wedge after it is driven. into place so as to prevent back-slip ping.

While I prefer to spike the rail on each side of a fastenerplate, and to secure the latter to a sleeper a single spike screw, yet modifications may be made without departing from the spirit of my invention.

1 claim as my invention:

1. A rail clamp comprising a fastener plate designed to be centrally-pivoted at or near one end on one side of a rail and having an overhanging lip at the other side of the rail and a Wedge designed to be driven he tween such lip and the base of the rail.

2. A rail clamp comprising a fastener end on one side of a rail and having an overhanging lip at the other side of the rail, said lip having a surface inclined or at an an ic to the vertical plane of the rail, and a We go designed to be driven between such lip and the base of the rail.

3. A rail clamp comprising-a fastener plate designed to be pivoted at one side of a plate designed-to be centrally pivoted at one rail base and having an opening therein-at 'or near one end and an overhanging hp at the other end, a pivoting element designed to be passed through said opening and into-a sleeper and to engage one side of the rail base, and a Wedge designed to be driven between said lip and the other side of the'rail base.

at. A rail clamp comprising a fastener plate designed to be one side of a rail an having means at its other end for engaging thebase of the rail at the other side thereof, said plate for the major portion of its length being normally ivoted at one end on held out of engagement with the sleeper to Y which it is pivoted.
