RAIL-ANTICREEPER.

Specification of Letters Patent.

Patented Apr. 3, 1917.

Application filed. February 14, 1916. Serial No. 78,166.

To all whom it may concern:

Be it known that I, PATRICK H. MOFAD- DEN, a citizen of the United States, residing at Spokane, in the county of Spokane and State of IVashington, have invented certain new and useful Improvements in Rail-Anticreepers, of which the following is a specification.

This invention relates to new and useful improvements in anti-rail creeping devices and the primary object of the invention is to provide a device of this character which is simple in construction and which will positively and firmly secure the rail in place on the tie against movement incident to con stant use under heavy trafiic.

It is a well known fact that rails have a tendency to creep over the ties and my invention primarily contemplates a means for the prevention of such creeping, which means does not involve a complicated and impracticable structure.

A further object of the invention resides in the provision of a chair plate or the like adapted to rest on a pair of ties and receive the rail thereon, the plate being provided with abutments for the rail base.

Still another object of the invention resides in the provision of a gripping plate removably applied to the chair and having teeth for engagement with the rail base.

A still further object resides in the provision of a device which is simple and durable in construction, inexpensive to manufacture and one which will be very efficient in use.

WVith these and other objects in view, my invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

In the accompanying drawings, forming a part of this application Figure 1 is a plan view of a track section showing devices constructed in accordance with my invention and applied to use in connection with the rail;

Fig. 2 is a plan view of the invention removed;

Fig. 3 is a side elevation thereof, the ties being shown in dotted lines;

Fig. 4 is a transverse section therethrough as seen on the line H of Fig. 2, the being shown in dotted lines; and

Fig. 5 is a perspective view of the toothed gripping plate removed.

In describing the invention, I shall refer to the drawings in which similar reference characters designate corresponding parts throughout the several views and in which l'designates ties upon which are mounted the rails 2 and 3, each rail being, as usual, formed of sections secured together by any approved form of rail joint 4t. Secured to each rail directly opposite the rail joint on the opposite rail is applied my improved anti-rail creeper, which I designate in the drawings generally as 5, and the detail description of which follows herebelow.

My improved anti-rail creeper consists of an elongated plate 6 which spans two ties, as shown in Figs. 1 and 3 of the drawings, the same being provided along one edge and at the ends thereof with a pair of abutments which are adapted to receive in contact therewith, the side edges of a rail base. The inner side edges of the abutments 7 are provided with recesses 8 which form continuations of openings passing through the plate 6 for the reception of rail spikes 9. Also formed integral with the plate 6 intermediate and spaced from the abutments is an additional abutment 10 which also receives the side edges of the rail base and contacts therewith, but this abutment is further provided with an overhanging lip or projection 11 which is designed to engage the upper face of the rail base, as clearly shown in Figs. 1 and 4: of the drawings. The plate 6 is further provided with pairs of openings 12 adjacent the ends and opposite the abutments 7 whereby spikes may be introduced therethrough for further securing the rail and plate in place on the ties. i 1

In positioning the plate 6 on the ties, the abutments 7 and 10 are preferably directed inwardly with respect to the rail, although the same may be positioned on the outer side. Formed integral with the plate 6 directly opposite the abutment 10 and on the inner side edge of said plate is an upstanding arcuate flange 13 and adapted to be positioned on the plate 6 in abutment with the flange 13 is a gripping plate 1 1. This gripping plate has the outer side edge thereof arcuate, conforming to the arcuate design of the flange 13, with which the same contacts, and the inner edge of said plate 14 has the lower 2 V f R 1,221,203

half toothed as shown at15. A central opening 16 is provided in the gripping plate 14through which a bolt 17 passes, the

: latter also passing through the plate 6 as shown in Fig. 4, and when they plate 14 is properly positioned, the teeth thereof are adapted to bite the rail base. The toothed portion 15 of the plate 14 is concaved to conform to the convex outline' of the edge of the rail base. By having the flange '13 arcuate and correspondingly designing the outer face of the plate,,14, the bolt 1 7 will be relieved of the strain due to expansion, gripping,"and pressure, and any longitudinal stress transmitted from the rail will causethe teeth of the plate 14 to bite tightly; To further prevent any longitudi- V nalmovementfthe inner face of the plate 13' and the outer face of the plate 14 are slightly beveled so'that the greater the strain upon ,the. bolt 17 the more tightly will the teeth he: forced to engage the rail base. For by thus bevelingj or tapering the flange 13 and the plate 14 at their'junctures and also providing for a slight space between the adjacent faces' of plates6 and 14, pressure upon the plate 14 through the bolt and nut will serve to drift the plate 14 toward the rail base to more securely grip the same.

' From the foregoing description of the con- 7 V struction of my improved device, the opera- 7 tion thereof and the manner of applying the same to use will be readily understood, and

it will be seen that I have provided a simple, efficient and inexpensive means for carrying out the. objects of the invention.

While I have particularly described the elements best adapted to perform the functions set forth, 'it is obvious that various changes in form, proportion and in the minor details of construction, may be resorted to, without departing from the spirit I cor-sacrificing any of the principles of the I claim and desire to secure by Letters invention. I ,"I-Ia'ving thus described my invention, what 7 Patent, is 7 1. In a rail anti-creeping device, a rail supporting chair adapted to rest upon the ties, means forsecuring'the chair to the ties, an

upstanding flange intermediate of said securing means and integral with saidchair,

the inner face of the flange being arcuate in form, a gripping plate having its outer face arcuate to conform to said inner face, the inner face of said gripping plate having a longitudinal straight toothed or serrated grooved portion adapted to fit over and engage the edge of the rail base, and bolting means for securing the gripping plate to the rail chair.

2. In a rail anti-creeping device, a rail support adapted to rest upon the ties, means for securing the support to the ties, an upstanding flange intermediate of said securing means and integral with said support, the inner face of the flange being beveled, a gripping plate having a beveled outer face to conform 'to the beveled inner face of said flange, the inner face of the gripping plate being provided with a serrated grooved rail engaging portion, and vertically disposed bolting means" for securing the gripping plate to the rail support.

3. In a rail anti-creeping device, a rail support adapted to rest upon the ties, means for securing the support to the ties, an upstanding flange integral with said support, the inner face of the flange being beveled, a gripping plate having a beveled outer face to conform to and engage the beveled inner face of said flange, the inner face of the gripping plate being provided with a grooved overlapping rail engaging portion, and vertically disposed means for securing the gripping plate to the rail support.

4. In a rail anti-creeping device, a rail support adapted to rest upon the ties, means for securing the support to the ties, an upstanding flange integral with said support, the inner face of the flange being beveled, a gripping plate having a beveled outer face to conform to and engage the beveled inner face of said flange, the inner face of the gripping plate being provided with a grooved rail engaging portion, the under face of said gripping plate being supported slightly above and away from the rail support between the flange and rail, and vertically disposed means for securing the gripping plate to the rail support.

In testimony whereof I afiix my signature.
