ANTICREE?ER FOR RAILROAD-RAILS.

Specification of Letters Patent.

Patented Apr. 25, 1916.

Application filed October 1, 1915. Serial No. 53,501.

T 0 all whom it may canoe-m Be it known that 1, DAVID F. VAUGHAN, a citizen of the United States, residing at Rivcrton, in the county of Burlington and State of New Jersey, have invented certain new and useful Improvements in Anticreepers for Railroad-Rails, of which the following is a specification.

invention relates to improvements in anticreepers for railroad rails, which are adapted to grip the rails and engage a sta tionary part of the road bed and prevent the forward, longitudinal displacement or the creeping of the rails.

The object of my invention is to m an anticrccpcr of novel, simple, inexpei'isi e and otlicicnt construction adapted to g a rail base, and held in gripping engagement with the raii base and in constant readiness for action under all conditions by the ac tion of a table spring associated with the parts of the antierecper and the rail in a novci manner to effect the desired result.

Witi'i this object in view the invention consists of the elements and the combina tions of their. hereinafter fully described and claimed.

In the accouuianying drawings, illustrating my invention: Figure 1 is a plan view of a portion of a railroad rail, a portion of a cross-tie supporting the sonic and-my improved anticrccper applied to the rail;' Fig. 2 is a side elevation of the parts shown in Fig. 1. Fig. 3 is a transverse section through the rail, on line 33 of Fig. 2. Fig. 4- is a transverse section through the rail and the anticroepor, on line 4-4 of Fig. 2. Fig. 5 is a perspective view of the spring.

Referring to the drawings, 2 designates a portion of a railroad cross-tie and 5 a railroad rail of usual construction. The cross-tic 2 forms a stationary part of the road bed which supports the rail 5\ and ,overh hich the rail tends to creep under the well known conditions.

My improved anticrecpcr is supported by the rail base 6 and is of the following construction: Extending bcncatu the rail base (i is a member or bar 7 having a hook or ide jaw formed on one end thereof which is hooked over and which engages one si e of the rail base 6, as shown. The other end of the bar 7 is provided with an upwardly extending arm 9 which is adapted to engage the side of the rail base 6 opposite to the side thereof engaged by the jaw 8 and prevent outward movement of the jaw from the rail base, when the parts arein the position shown in the drawings.

The arm is provided with an opening 10 into which is inserted the outwardly projecting arm 11 of a keeper 12 which rests against the inner face of the arm 9 and extends over the adjacent side of-the rail base 6 and engages the top thereof andpre vents downward movement of the end of the bar 7 carrying the arm 9. The arm 11 of the keeper 12 is provided with a shoulder 11 which is adapted to engage the adjacent edge of the rail base 6 and prevent displacement of the l-zcepcr 133 from the arm 9 when the parts are in the position shown in the drawings. When it is desired to remove the anticrccpcr from the rail, the end of the bar 7 carrying the arm 9. is raised so that the shoulder 11 clears the edge of the rail base (i. The arm 11 is then withdrawn fron'i' the opening 10, and the end of the bar 7 carrying the arm 9 is then lowered until the arm 9 is below the plane of the bottom of the rail 5. The jaw 8 may then be moved outwardly from the rail base. The anticrceper may be appliedto the rail by a reversal of the operation just described.

The top of the bar 7 is provided with a depression 13 therein in which is placed a suitable spring 1 1, preferably helical in form, as shown. Normally thev spring 14, rests upon the bottom of the depression 13 and the upper end of the spring extends above the top of the bar 7 a suthcient distance to cause the spring 14 to be compressed when the anticreeper is applied to the rail. so that, after the anticreeper has been applied to the rail, the spring 14 will force the bar 7 downwardly and thus force the keeper 12 and the upper part of the jaw 8 down upon the rail base 6 and serve to firmly hold the anticreeper in gripping end which is adapted to engage'the cross-tie 2 and prevent the rail fromcreeping. The

abutment portion 16 of the anticreeper is preferably located adjacent to one end of the ar 7 so that the other end of the bar 7 will be maintained out of contact with the crosstie 2. Should the rail 5 attempt to creep forwardly, the abutment 16 will engage the cross-tie 2 and prevent forward movement of the end of the bar 7 carrying the abutment 16, while the rail 5 will carry the other end of the bar 7 forwardly; and, immediately upon the initial creeping movement of the rail 5, the bar 7 will tend to assume a diagonal position beneath the rail 5, forcing the arm 9 and the wall 17 of the jaw 8 inwardly against the respective sides of the rail base 6, thus causing the anticreeper to increase its grip upon the rail.

I referably provide the wall 17 with outwar ly diverging faces, as shown in Fig. 1, which meet in a central hearing which engages the side 'of the rail base 6 to bring the strain within the jaw 8 centrally of the bar 7; and I provide the wall 18 of the arm 9 which engages the side of the rail base 6 with similar outwardly diverging faces, as shown in Fig. 1, which meet .in a central hearing which engages the side of the rail base to bring the strain centrally of the arm 9 and bar 7 when the anticreeper grips the rail by the action of the bar 7 in tending to assume the diagonal position, as previously explained.

he wall of the depression 13 surrounding the spring 14 prevents displacement of the spring from its operative position; and, by the novel construction hereinbefore described, I am enabled to employ the well known helical spring commonly used to hold nuts in place in railroad structures, as the spring means which maintains the anticreeper in gripping engagement with the rail, so that such springs which are used in great numbers and are available in nearly all localities along the tracks of railroads may always be at hand for use in connection with my improved anticreeper.
