Pat ated Sept. 15, 1936 UNITED STATES RAILWAY TIE PLATE George T. Willard; st. Louis', Mo.

Application August -Z7 9 Claims.

This invention relates to railway tie plates; An object of the invention is to provide an improved railway tie plate equipped with means for resiliently holding the rail on the plate by the application of yielding pressure against the outer vertical face of the rail base ange to eliminate or retard creeping of the rail without rigidly attaching the rail and the plate together. It is desirable to avoid rigid connection of the rail with the plate because where such rigid connection is provided, there is a tendency to lift the tie from its bed by the wave motion of the rail under rolling load.

Iie plates embodying this invention may be rigidly attached to the ties by any appropriate fastening means, such as screw spikes or bolts, which reduce mechanical wear on the ties.

My novel and improved connecting means for resiliently connecting the rail and the tie plate exerts pressure in a horizontal direction against the rail base flange and may also embody means for yieldingly bearing on the upper surfare of the rail base ange to retard or limit the upward vertical movement of the rail relatively to the tie plate during wave motion of the rail under rolling load. This connecting means for resiliently holding'the rail on the plate is preferablyl held under tension by an adjustable holding device provided for that purpose. f

The resilient connecting means for holding the rail on the tie plate is movable vertically with the rail but is substantially held against horizontal movement With-the creeping of the rail by lugs or shoulders formed on the upper surface of the tie plate adjacent to the edge of the rail base and these lugs or shoulders may be formed integrally with the tie plate in the rolling of the.

tie plate or during the finishing process.

While the resilient connecting means between' the tie plate and the rail is movable vertically with the rail, nevertheless said connecting means holds the rail under downward pressure asl well as horizontal pressure. When the connecting means is used on only one side of the rail base flange, the opposite edge of the rail base flange will be in cooperative relation to a shoulder rising above and extending over to overhang the rail base flange but spaced therefrom to allow the free vertical movement of the rail wave motion under rolling loads. l

Other objects and advantages of the invention will be apparent from the following description, reference being made to the annexed drawing; in which- 1934,(seria1No. '141,559

(Cl. 23S-283) Fig. 1 is a perspective view of a tie plate. anu rail engaging means embodying my invention.

Fig. 2 is a top plan view -of the tie plate and rail engaging means, the web of the rail being in section.

Fig. 3 is a. vertical cross sectional view on the line 3--3 of Fig. 2 of the tie plate showing the resilient connecting means in one useful relationship to the tie plate and the rail base flange.

Fig. 4 is a similar vertical cross sectional view of the tie plate showing the resilient connecting means in another useful relationship relatively to the tie plate and the rail base iiange.

In the embodiment of the invention chosen for l illustration, a tie plate I is formed with a seat 2 between transverse shoulders 3 and 4 upon which may be placed a cushion 5; or said cushion 5 may be omitted, if desired. The tie plate is formed with holes 6 for the reception of screw spikes or bolts l for fastening the tie plate on the tie 8.

The rail base 9 may be seated on the cushion 5, when said cushion is used; or'may be seated directly on the seat 2 when the cushion is omitted. In the illustrated form of the invention, the shoulder 3 is formed with a laterally extended marginal portion l!) which projects above theadjacent marginal portion of the base 9 and functions to prevent the rail from overturning.

My improved resilient connecting means in the form of a spring clip is designed to exert va lateral tension against the vertical face of the rail base flange 9, which will prevent the rail from creeping; and is also designedto exert a lesser downward pressure or tension on the top of the rail base to retard the wave motion and stiien the track structure. The lateral and downward pressures may be varied in tension by an adjustable nut or by varying the thickness of the spring clip to obtain a semi-rigid construction as required by the conditions of use. This improved connection between the tie plate and the raileliminates or minimizes the churning of the ballast and the consequent shattering of the ties, which destructive effects are incident to the use of tracks in which the rails are rigidly attached to the tie plates and to the ties. l

As shown in Fig. 3 of the drawing, the 'spring clip has one end I I seated upon the marginal portion of the rail base 9 and a portion I2 exerting a lateral pressure or tension against the adjacent vertical face I3 of said rail base, theopposite end portion I4 of the clip being engaged in a hol I5 in the tie plate I and supported by a shoulder I6 on the clip seating von the upper surface of the tie plate. A bolt I'I extends through a hole I8 in the tie plate I and through an elongated hole I9 in the spring clip and securely holds the spring clip in the relation shown and described. The tension of the spring clip may be varied by varying the position of the nut 20 on the bolt, as should be apparent by reference to the drawing.

The cushion 5, shown in Fig. 3 of the drawing, absorbs whe'el shocks, reduces maintenance costs and prolongs the life of the ties and the metal parts While deadening or minimizing noise and obtaining smoother riding track. In this arrangement, the end of the spring clip II engages the rail base but does not seat upon the upper surface of the tie plate. The spring clip extends through a notch 22 in the shoulder 4 and is thereby held from displacement. Obviously the spring clip ends I4 and I6 may be held in place otherwise than A as shown, as by abutments on the top of the tie plate, or by an auxiliary shouldered rigid clip tting over the bolts I`I and 29, or otherwise as desired.

In the relationship of the parts shown in Fig. 4, the cushion is omitted, the end portion 23 of the spring clip extends over but does not seat against the upper surface of the marginal portion of the rail base 9, being separated therefrom by a slight space 24. The portion 25 of the spring clip exerts a lateral tension against the vertical face I3 of the rail base and seats upon the upper surface of the tie plate I in the notch 22. The opposite end portion 26 of the spring clip extends into a hole 2'I in the tie plate and is supported by a shoulder 28 seating on the tie plate. The bolt 29 extends through the hole I8 in the tie plate and through a hole 30 in the clip, corresponding to the hole I9, and is equipped with a nut 3l, whereby the tension and pressure of the spring clip may be varied, as desired.

It should now be apparent that this invention attains all of its intended objects and purposes efficiently and satisfactorily and that the invention may be varied within the scope of equivalent limits without departure from the nature and principle thereof.
