Specification of Letters Patent.

Patented Aug. 26,1913.

Application filed February 1, 1913. Serial No. 745,579.

To all whom it may concern:

Be it known that I, DAVID F. VAUGHAN, a citizen of the United States, residing at Haddonfield, county of Camden, State of New Jersey, have invented a certain new and useful Improvement in Anticreepers for Railroad-Rails, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

The present invention relates to devices for preventing railroad rails from moving lengthwise under a tendency so to do imposed thereon by railway rolling stock traveling over them and it has for its object "mple and efficient de vice for the purpose specified, and one which may easily be applied and removed and which cannot easily be damaged or put out of repair in applying it to a rail or removing it therefrom.

The various features of novelty whereby my invention is characterized will hereinafter he pointed out with particularity in the claims; but, for a full understanding of my invention and of its object and advantages, reference may be had to the following detailed description taken in connection with the accompanying drawing, wherein:

Figure 1 is a top plan view of a portion of a railway tie and a railroad rail thereon,

'with the improved antici'eeper in position on the rail; Fig. 2 is a section on line 2-2 of Fig. 1, showing the parts of the anticreeper in the positions which they occupy just before they are looked upon the rail; and Fig. 3 is a side view, looking toward the right in Fig. 2, showing in dotted lines the unlockedposition ofone of the members and in full lines the locked or opera tive position of that member.

Referring to the drawing, 1 represents a railroad rail having the usual base flange, 2, the rail resting upon suitable cross ties one of which is indicated at 3.

For the sake of illustration it is assumed that the tratlic is in a direction tending to move the rail in the direction of the arrow A in Fig: 1 and, for the sake of clearness this will be called the forward direction while the opposite direction will be called the rearward or backward direction.

The .anticreeper comprises two 'simple parts adapted to be engaged with the base flange of the rail behind the cross tie which serves as an abutment or fulcrum for the anticreeper; one of said parts being preferably made of a piece of plate steel and the other in the form of a forged or cast block or shoe. The sheet metal member comprises a bar, 4, having projecting pieces, 5 and '6, at the ends, the distance between the inner edges 7 and 8 of the members 5 and 6 being somewhat greater than the width of the base of the rail. The part 5 has at its outer or upper end a piece 9 which is spaced apart from the member 4 and is preferably bent forwardly therefrom as will best be seen in Fig. 1.. The upper or outer end of the member 6 is bent rearwardly at an acute angle to the plane of the member 4, as indicated at 10.

The cast or forged member of the anticreeper is indicated at 11 and has in one side 12, adapted to fit over one edge of the rail base. On the side of the block or shoe 11 opposite to that in which the jaw 12 is located, is a projecting lug, 13, having a rearwardly inclined front face 14. The an{ gle of the face 14 is the 'same as the angle a jaw,

of the part 10 relative to the plane of the bar 4 and the main portion of the end piece 6:

In applying the anticreeper to the rail,.

the shoe is first adjusted upon one of the base flanges of the rail with its front face in contact with the tie. The other member of the anticreeper is then hooked'over the opposite base flange of the rail as shown in Fig. 2 and is swung around until the end 6 lies just below the lug 13 on the shoe, as indicated in Fig. 2 and by the dotted-lines in Fig. 3. The bar 4 and its end piece 6 are then twisted and raised so as to bring the inclined upper end 10 of the member 6 in front of the lug 13. Because of theinclination of the front face of the lug 13 and the inclination of the part 10, the lug serves both as an abutment to prevent a rearward twisting movement of the adjacent end of the bar member of the anticreeper and as a shoulder to hold the adjacent end of the bar-member from dropping down. The bar member is made of spring metal, preferably steel and therefore when it is twisted into position, it is placed under a torsional tension which the member 10 firmly against the inclined front face of the lug 13 on the shoe.) Con sequently the anticreeper is inade to grip the base of the rail firmly and itstwo parts are effectively locked together in position. In order to unlock the two parts of the anticreeper so as to remove the same from the rail it is only necessary to pry the bar memher out of engagement with the shoe.

When the anticreeper is in place, a tendency on the part of the rail to creep forward will be prevented by the cross tie, the rail in such forward movement carrying with it the end of the bar member of the anticreeper opposite the shoe and the slighest forward movement of the rail resulting, in swinging the bar member of the anticreeper diagonally of the rail and forcing the inner edge 7 of the member 5 firmly into engagement with the onter'edge of the base flange and consequently forcing the shoe 11 firmly against the other edge of the base flange and so firmly gripping the rail and preventing it from creeping, It wili be seen that the tendency on the part of the rail to creep applies a pressure on the inclined portion 10 of the bar member of the ant-icreeper in the direction tending to press'it more firmly into engagement with the lug 13 on the shoe so that accidental disengagement is impossible.

It will now be seen that I have produced an extremely simple and compact device which is ruggedly made so that it will stand rough usage in assembling, removal, or in actual operation without danger of injury or having its functions impaired.

a part adapted to hook over the opposite edge of the railbase, said shoe having a rear wardly-directed face for engaging with the side of said her and a laterally-projecting lug above and spaced apart from said face, said lug having a downwardly and forwardly inclined front end, and the end of the bar adjacent to said shoe having an npwardly-projecting portion provided at its upper end with a rearwardly-inclined part adapted to fit against the front end or" said lug.

2. Adevice of the character described, comprising a shoe shaped to fitv over one edge of a rail hase, a bar of spring metal having a part adapted to hook over the opposits edge of the-rail base, said shoe having a rearwardly-directed face for engaging with the side of said bar and a laterallyprojecting lug above and spaced apart from said face, the end of the bar adjacent to said shoe having an upwardly-projecting portion provided at its upper end with a part adapted to hook over said lug.

' In testimony whereof, I sign this specification in the presence of two witnesses.
