' ANTICREEPER- FOR RAILS.

Specification of Letters Patent.

Patented Sept. 12, 1011.

Continuation of application Serial no. 502,565, filed June 16, 1909. This application filed March 31, 1910. Serial 12:0. 552,680.

To all-whom it may concern:

Be it known that I, SANTA E. NELSON, a citizen of the United States, residing at Kennett, in the county of Shasta and State of California, have invented a new and useful Anticreeper for Rails, of which the fol lowing is a specification.

The invention relates to improvements in anti-creepers for rails, and is a continuation of a former application, filed June 16, 1909, Serial No. 502,565, for a similar device.

The object of the present invention is to improve the construction of anti-creepers for rails, and to provide a simple, inexpen sive and efli cient anti-creeper of great strength and durability, capable of firmly gripping a rail and of engaging a cross tie for preventing rails from sliding downward on a grade.

A further object of the invention is to provide a boltless and wedgeless anticreeper, adapted to be easily made and capable of being readily applied without change to rails "of different sizes.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended 3 it being understood that various changes in the form, proportion, size and minor details'of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawin :-Figure 1 is a side elevation of an anti-creeper, constructed in accordance with this invention and shown applied to a rail, the latter being in section. Fig. 2 is an end elevation of the same. Fig. 3 1s a perspective view of the anti-creeper detached. Fig. 4 is a similar view, showing anolther form of the invention on a reduced sea e.

Like-numerals of-reference designate corfrom a single strip of metal, approximately rectangular in cross section bent interme diate of its ends to provide a depending approximately U-shaped loop 2, which is 10- cated beneath the rail 3 centrally of the same below the web thereof, as clearly shown in Fig. 1 of the drawing. The metal. is extended horizontally at one side of the loop 2 to provide an arm 4, fitting against the lower face of the adjacent bottom flange of the rail. and having an upwardly extending hook-shaped terminal 5, which is engaged with' the side edge of the adjacent bottom flange. The hook-shaped terminal 5 is slightly curved, as shown, to conform to the configuration of the upper face of the engaged edge of the bottom flange of the rail. The strip of metal of which the anti-creeper is constructed,is extended outward horizontally from the opposite side of the depending U-shaped loop to form a rail engaging arm 6, which has a horizontal upper face to grip the lower face of the bottom flange at the opposite side of the rail from that engaged by the hook-shaped terminal 5. The terminal portion of the strip at the arm 6 is bent into approximately circular shape, forming a spring loop 7 having a downwardly extending terminal portion 8 at the inner side, located at a point directly above the horizontal rail gripping arm 6, and presenting a horizontal end face to the rail and cooperating therewith to clamp the interposed bottom flange. The end face 9 of the terminal portion 8 corresponds with the plane of the upper face of the bottom flange of the rail and fits against the same presenting its entire area. to the rail. The loop 7 by extending upwardly from the outerend of the arm 6 and curving inwardly over the bottom flange of the rail and downwardly to the same, as clearly shown in Fig. 1 of the drawing, is adapted to cooperate with the 1 horizontal arm 6 in firmly gripping the base of the rail.

The anti-creeper, which engages the bottom of the rail 3 at opposite sides thereof, is designed for use on grades, and is adapted to be arranged above a cross tie 10 on the said grade. ,It is set at an inclination, the depending lower loop extending downwardly and arranged at an acute angle to the adjacent face 11 of the cross tie. The anticreeper is beveled at'the inner engaging face or side 12 of the depending approximately U-shaped loop at the bottom thereof, and it thereby presents an engaging face, which fits squarely against the cross tie, as clearly shown in Fig. 2 of the drawing. The said tie-engaging face is arranged at an obtuse angle to the adjacent side face of the depending loop. The rail-engaging faces fit that against the bottom flanges of the rail when the device is placed in position, and any tendency of the rail to slip or slide causes.- the depending loop to approach nearer a perpendicular position, which results in an 7 ncreased clamping action of the anticreeper on the rail, and thelatter is thereby firmly held in place with respect to the cross It will thus be seen that when the device is subjected to the strain incident to the creeping of the rail, itfis caused to grip the rail more firmly and that-the gripping action increases with the force of the said strain.

In ap'plyingthe device to arail, one of the bottom flanges thereof is introduced be-- tween the engaging end of the loop 7 and the horizontal arm. 6 at that side of the depending loop. The o-the'r laterally extending arm is engaged with the bottom flange of loop to the outer engaged terminal 5 of the be easily applied to a rail.

arm 4. This will render the anti-rail creeper sufficiently resilient to enable it to In Fig. 4 of the drawing is illustrated another embodiment of the invention having a depending approximately U-shaped loop- 13, designed to be located centrally beneath the rail, similar to the loop 2 heretofore described. The metal is extended at one side of the loop 13 to form a horizontal arm 14, having a hook-shaped termina 15 to engage the base of the rail at the outer edge of one of the bottom flanges thereof. The metal is extended at the opposite side of the loop 13" and bent back on itself to provide a horizontally disposed U-shaped loop 16, which is arranged to embrace the other bottom flange of the rail. The terminal portion of the strip at this end of the clamp is bent to form an upwardly extendingapproximately U-shaped loop 17, the outer side 18 of which presents a terminal oint 19 to the upper face of the flange oi the rail. The. anti- .creeper engages the bottom of the rail at opposite sides in the manner'heretofore described, and any sliding or creeping of the rail carries the depending loop 13 in a direction of the crossv tie, which movement is resisted by the outer side 18 of the upwardly extending loop 17. The side 18 is caused to bite the rail and embed itself in the upper face of the bottom flange thereby effectua ly resisting the downward creepingof the red and increasing the clamping action or force with which the anti-creeper engages the rail.

In each of the forms of the invention, the opposite rail engaging portions, which extend from the sides of the depending loop, are maintained in engagement with the base of a rail solely through the resiliency of the said loop.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is
