TIE PLATE Fil'ed April 5, 1930 7 arrzrzer Patented Oct. 14, 1930 UNITED STATES JOHN T. WARRINER, 0F RICHMOND, VIRGINIA TIE PLATE Application filed April 5, 1930. Serial No. 441,899.

This invention relates to tie plates, and it is an object of the invention to provide plates of this kind which, when applied, afford effective means to prevent a track from spreading and wherein the plates are so constructed that upon a derailment the wheels of the rolling stock will only cut spike heads oh" on every other tie, thus leaving the track in a safe condition.

The invention also has for an object to provide a tie plate which extends a material distance beyond opposite sides of the associated rail and entirely across the tie whereby to prevent, upon a derailment, the wheels of the rolling stock cutting into the ties.

An additional object of the invention is to provide a tie plate wherein a plurality of holding spikes are employed in connection therewith and which must be entirely removed before displacement of a plate. This is of especial advantage in preventing a highwayiian attempting to pull the spikes or to remove a plate to cause a rail to turn.

A further object of the invention is to provide a plate of this kind wherein the rail supporting surface is disposed on an angle to cant or slant the rail inwardly of the trackway so that the ball of the wheel will travel on the center of the rail causing the rail to wear longer and to more effectively distribute the load on the rail.

Another object of the invention is to provide a plate of this kind which, when applied on a tie, will remain in the right position for the entire life of the tie and at the same time will add from one to five years to such life.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved tie plate whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, T will now proceed to describe the same with reference to the accompanying drawing, wherein Figure 1 is a view in top plan illustrating a pair of tie plates constructed in accordance with an embodiment of my invention and in applied position, the coacting rail being indicated by broken lines;

Figure 2 is a fragmentary transverse sectional view taken through Figure 1 with the associated rail shown in full lines;

Figure 3 is a fragmentary view in end elevation of a second tie plate herein" embodied.

As disclosed in the accompanyingdrawing, my improved tie plates P and P are adapted for engagement with the opposite sides ofa rail R and such engagementis preferably obtained by said plates being alternately placed on succeeding ties T.

Each of these plates]? and P comprises an elongated body 1 of desired metal and of awidth substantially equal to the width of the associated tie T. The plate P or P, how

ever, is of a length to extend a material distance beyond the opposite sides of the rail R resting thereon. Disposed transversely of each of these plates is an overhanging flange 2 integrally formed with the body 1 and which is adapted to engage over the longitudinal marginal portion of the base flange of t-helrail R. The portion of the upper surface of the body 1 immediately inwardly of the flange 2 constitutes a rail bearing bed 3 and on plate P this bed 3 is inclined upward- 1y from the flange 2 whereas upon the plate P this bed 3 is inclined downwardly from the flange 2. The angles of inclination of the beds 3 on bothof the plates P and P are of the same degree and these beds are reversely inclined as just described in view of the fact that the flange 2 of the plate P engages the rail flange inwardly of the rail while the flange 2 of the plate P engages the outer marginal portion of the rail. The inclinations of the beds 3 also provide positive means for canting or slanting the rail R inwardly of the trackway so that the balls of the wheels of the rolling stock travelling over the rail R will be positioned on the center of the rail. This is of advantage as the rail will wear longer and the load will be evenly distributed throughout the entire rail.

The end portion of each of the plates P and P outwardly of the flange 2 thereof is provided with transversely spaced spike openings 4, while the opposite end portion of the plate is provided with the spike openings 5. Inwardly of the openings 5 each of the plates P and P is provided with additional openings 6 through which are directed spikes for engagement with the base flange of the rail R at the side thereof remote from the flange 2 carried by the same plate.

By having the plates P and P relatively large in size, an effective protection is provided for the tie especially upon derailment as the wheels of the rolling stock will not tear into the ties proper and, furthermore, by having the flanges 2 of the platesP and P engaged with opposite sides of the rail R, upon derailment the wheels will only be liable to cut spike heads 05 on every other tie, thus leaving the track in a safe condition. It is also to be noted that each of the plates P and P, in the present embodiment of my invention, has employed in connection therewith six spikes each of which will have to be pulled before the plate P or P can be removed to allow the rail R to turn. This is of advantage in eliminating the tendency of a highwayman to remove such plates.

The under surface of each of the plates P and P is provided thereacross with the ribs 7 which assure more eflective maintenance of the plate in applied position upon a tie T.

From the foregoing description it is thought to be obvious that a tie plate constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim In combination, a pair of tie plates provided thereacross with rail engaging flanges, the flange of one plate engaging the outer side of the rail and the flange of the second signature.

JOHN T. WARRINER.
