ANTICBEEPING CLAMP.

Application filed September 9, 1922. Serial No. 587,063.

i To all whom it mca-y con oern.

Be it known that I, lVILLmM J. Cos'rnLLo, residing at Penn Township, in the county of Allegheny and State of Pennsylvania, a citizen of the United States, have invented or discovered certain new and useful Improve ments in Anticreeping Clamps of which improvements the following is specification.

The invention described herein relates to what is sometimes termed anti-creepers. for rails, i. e., devices secured to rails intermediate the cross-ties and adapted to bear against the latter to prevent material move ment of the rail on the cross-ties and to maintain a proper spacing of the latter.

' one having a resilient eleinentand the other a finger which when the two members are applied to the flange of rail, will force the spring element against the underside of the rail flange. It is a further characteri..- tic of the improvement that the hooks are so constructed that the free end of the hook will bite on the upper surfaces of the flanges. The invention is hereinafter more fully described and claimed. i

In the accompanying drawing forming a part of this specification, Fig. 1 is a sectional elevation of a rail having the improved anti-oreeping device applied thereto; Fig. 2 is a side elevation of a rail and a cross-section of a cross-tie, the rail having the improved device applied thereto; Fig. 3 is a view of the underside of a rail and showing the device in position thereon.

In the practice of the invention one member A consists of a hook so constructed. that the body portion 1 will bear on the underside of the flange of the rail while the other leg 2 or"? the hook is so shaped that it will hear at its end on the upper surface of the flange. The extension of the body portion the other member without any tendency to force such member outoii position.

It is preferred that the members should be square in cross-section except the prong which is made round so as to fitinto the ring. This prong as its end a little smaller than the inner diameter of the ring so as to facilitate its insertion. andincreases in diameter so that-when the member 13 is driven to position, the ring will be expanded and the linger 4; caused to bear tightly against the underside of the rail flange.

It will be observed by reference to Fig. that LllG device is so applied that the ring will bear of the arrow Y2. l/Vhen the prong is forced. into the ring it will cause an expansion of the ring and such movement of'the end of the finger 4 as to cause it to bite into the rail and prevent a movement of the device relative to" the rail. It will be observed that the portions 2 and 5 off the members A and B bearat their ends on the upper faces of the rail flanges; as these portions of the devices are made square, corners will bite into the rail when pressure is applied. as before described, to the ring.- such pressure tending to move the devices to an angular position relative to the rail.

I claim herein. my invention: I

1. Means tor preventing the creeping of railshavingin combination a hook adapted to engage flange eta rail and the part ex- 1 ling underthe ail provided with a re- 81116. J ringer, a. second hook also adaptedto engage the rail flange and provided with a prong adaptedlo force the resilient linger into engagement with the underside of the rail flange.

ion of the arrow a the pressure of the de-. l

2. Means for preventing thecreeping of adapted. to be forced into the ring of the ether hook and expand the ring whereby the finger is caused to bear firmly en the under- 10 side of the rail.

In testimony whereof, I have hereunto set my hand.
