Specification of Letters Patent.

Patented July 1 1913.

Application filed June 25. 1910: Serial No. 568,860.

Be it known that. I, FREDERICK I'm-1srox, a eitizen'ot' the United States, residing at Highland Park, in the county of Lake and State of Illinois, have invented new and useful Improven'ients in Means for Proventing the Creeping of Rails, of which the following is a full. clear. concise, vand exact description, reference bein had to the accompanying, drawing. forming a part of this specification.

My invention relates to means for preventing the creepin of rails.

The object of my invention is to provide a tie plate which shall perform its usual functionand in addition shall beadapted and arranged to cooperate with some means for gripping the flanges of the rail and prevent creeping thereof.

Other objects of my invention are to provide a tie plate adapted to be secured to the tie by the usual spikes and which may have in addition, means for cooperating directly with the tie itself to relieve the spikes from some, or the greater part of the shearing stresses dueto the creeping tendency of the rail; to simplify the construction so as: to

employ only a minimum of parts to accon'iplish the desired ends, certain of which parts i shall consist of means adapted to be readily grip thereon by a wedging action under the rail, upon any tendency of the rail to creep. Other advantages will appear, from the description which follows.

While my invention may heeml iodietl in a number of Concrete forms, I have illustrated in the accompanying drawings only one such form. the latter constituting a simple and effective arrangement. for accomplishing the desired results.

In the drawings: Figure 1, is a plan View -\'ersel v and longitmlinally, as clearly shown in Figs. 2 and Extending downwardly from the same end of the tie plate, from which projects the tongue 3, there. is provided a downwardly extending shoulder or arm 6 for engagement with a side of the cross-tie T. on which the plate 1 is secured, and reinforced preferably by a flange 8. This downwardly extending arm is preferably arranged substantially in alinement with the tongue 3- although I do not limit myself to this construction. It should be noted that the tongue 3 is preferably located a slight distance to one side of the longitudinal axis of th tie plate for a purpose hereinafter specified. The tie plate may be made in two forms, right. hand and left hand constructions being provided, although in this application one form only is illustrated, the principal of operation being identical. with either form.

The rail gripping member may be of various suitable forms and is shown in the present instance as a one piece construction in the form of a yoke 9, having integral clip i mcn'ibers iOaud it atopposite ends thereof, applred to a rail and adapted to increase the and having preferably widened ends 12 I adapted to firmly grip the things of the call, the opening of at least one of the jaws or "lip membcrs being slightly smaller than longitudinally and transversely to correspond. to the double beveled surfaces 4 and t .3, of the under side of the proye tmg tongue of the tie plate and rail anchor in position,

the rail being shown in dotted outline. Fig. 2. is a side elevation of both members, with the removable member about to be driven toward the stationary i'nember. Fig. 3. is an end ele ation of the parts in assembled position. Fig. t, is a detail.

The tie plate proper consists of a plate 1, having a plurality of holes 2, adapted to re cei've the usual spikes, not shown, and having preferably the usual. sharp, downwardly extending ridges on its under side, although 3. lteinforcing rib l5, 15 are shown in connection with the jaws l0 and 11. these ribs having their extremities: deflected as shown particularly in Fig. 1. to give strength where it is most needed. although I do not limit myself to this construction.

One end of the yoke 9 is preferably curved or providm'l with a crown 16. for the pur- I do not limit myself to this construction.

the jaw..- 20 and it is cm ang es f greater than the width of the rail to which the yoke is to be applied. in the form illustrated. This permits the yoke to be placed under the rail, approximately at right angles thereto, with the jaw 11 embracing one flange of the rail. .In this position, the other jaw 10 may be forced or sprung up until it just clears the other flange of the rail,

whereupon it is driven by side blows until it catches on said flange or it may be made to engage said flange in other ways. This clip member 'could be caused to pass above the flange of the rail, leaving a considerable clearance, if it were not for the crown 16, avhich in the form illustrated necessitates the forcing or springing of said member over said flange just far enough to clear it. By driving the yoke around to a diagonal position with respect to the length of the rail, it is apparent that" the clip members 10 and ll will ride up along the upper surfaces of the rail flanges, thereby preventing the yoke from dropping fro-m the rail. In lriving the yoke to this diagonal position, the clip member 10, riding up on the rail flange, causes the crown 16 to bring considttrable pressure to bear against the under side of the rail, thereby springing the yoke downwardly and effecting a very firm hold of said yoke, which distortion is possible owing to the fact that this form of yoke is preferably made of malleable iron, cast steel, or similar material httving some ability to yield; l

Before driving the yoke around to its extreme diagonal position on the rail, it is driven longitudinally of the rail toward the tie plate 1, until the projecting tongue of said plate enters the recessed or cut, away portion and wedges itself firmly therein, under the rail. The yoke may now be firmly driven to its extreme diagonal position on the rail and made to ride down as far as possible on the beveled under surfaces i and 5 of the tongue In this position, creeping of the rail will be prevented by the firm gripping or pinching of the jaws or clips 10 and 11 on the flanges of the rail, due to the driving lit and to the crown, movement of the yoke as a whole being prevented by the wedging connection under the rail. and movement of the tie plate as a whole being prevented by the downwardly extending arm ti which abuts against the side of the tie, and by the spikes which take up part of the thrust. I do not desire, however to limit myself to this diagonal position for the yoke, as it may be otherwise located and otherwise sprung into place.

The tongue 3 is not wide eno h to completely till. the recessed portion of the yoke 5t and maintains its hold thereon entirely through the frictional engagement. of its under or wedging surfaces, which co-act with the beveled surfaces of the yoke. This wedging engagement is effective Preferably at one side of the center line of the tie plate as a whole, inasmuch as the projecting tongue 3 located a little to one side of the center of the tie plate, as previously pointed out, and inasmuch as the recessed or cut away portion of the yoke 9 is also located a corresponding distance to-one side of the middle of the yoke. As a result of the above off-set arrangement, any tendency of the rail to creep, after the parts are once in their assembled position, will cause said yoke to tend to twist or turn still farther with respect to the rail, thereby increasing its frictional hold thereon, by virtue of the driving fit of the jaws, and will also cause an increased wedging action under the rail.

-[ do not limit myself to this twisting action however.

Owing to the fact that the jaws 10 and 11 have preferably a driving fit on the flanges of the rail, they will maintain their" hold independently of the wedging action of the tongue 3, so that when the rail undergoes a rearward movement, as sometimes occurs, said yoke will be drawn back with the rail, but will maintain its hold on the flanges, so that upon a return forward movement of the rail, the yoke will again engage the tongue of the tie plate and prevent further creeping.

I desire not to limit myself to the form illustrated or to the details of construction shown and described, as it is obvious that other forms and other details may be devised which will embody the broad features of the invention and which will fall within the scope of the various appended claims.

Having thus described my invention,what I claim as new and desire to secure by Letters Patent oft-he United States, is
