This invention relates to railway track structures, and has particular reference to improvements in tie plates and rail anchors.

thereof for disposition at a side of a tie upon which the tie plate is seated, and to provide said lip with an upwardly opening channel extending longitudinally relative to the tie plate to accommodate the lower portion of a C-shaped rail anchor engaged with a flange of the rail, whereby the rail anchor may be held effectively against sidewise movement relative to the tie plate and thus may be rendered particularly effective to resist longitudinal creeping movements of the rail, the lip, disposed as stated, avoiding any necessity of providing'a rail anchor of special form for use with the tie plate and advantageously enabling the use therewith of rail anchors of a known or Standard type.

Another special object of the invention is to provide in the lip of the tie plate a recess to accommodate a lug which may readily be provided on a rail anchor of the type which is to be used in association with the tie plate, thereby to provide for interlocking the rail anchor with the tie plate against any possibility of the same movingoutwardly from its applied position upon the rail flange. In this connection dependence may, if desired, be placed in the interlock afforded by said lug and recess to hold the rail anchor against sidewise movement relative to the tie plate, in which event channeling of the lip is unnecessary. It is preferred, however, to employ said lug and recess in association with a channeled lip as thereby a stronger and more dependable structure is afforded.

Another special object of the invention is to provide a tie plate and a rail anchor both of which may readily be formed at comparatively low cost for cooperation with each other in the manner and for the purposes stated.

With the foregoing and other objects in view, which will become more fully apparent as the nature of the invention is better understood, the

6 Claims. (o1.'23s 315) same consists in a tie plate and a rail anchor 2 v 1 Figure 3 is a plan view illustrating one practical manner of cutting a rolled tie. plate bar to provide individual tie plate sections for forming by forging into individual tie platesembodying the features of the invention.

Referring to the drawing in detail, it will be observed that a tie plate constructed in accord ance with the invention includes a main body portion Hi to seat upon across tie l l and to have a rail l2 seated thereon, and a lip I3 extending from a side of said main body portion'for cooperation with a rail anchor l4 engaged with a base flange of the rail l2 to hold said rail anchor operatively positioned upon the rail and particularly effective to resist tendency of the rail to creep longitudinally.

The main body portion 10 of the tie plate may be of any usual or any preferred construction and the lip l3, preferably is an integral part thereof, although it may be a part separate therefrom and fastened thereto in any suitable manner. In any event, said lip is of a width to project beyond the side of the tie when the tie plate is operatively positioned upon the tie, and the portion thereof which projects beyond the side of the tie is extended first downwardly, as indicated at l5, then outwardly, as indicated at [6, and then upwardly, as indicated at H, to provide therein an upwardly opening channel [8 extending longitudinally relative to the .tie plate and transversely relative to the rail.

The rail anchor I4 is of C-shape and may be of a known or Standard design. It includes upper and lower legs [9 and 20, respectively, and is adapted to be applied to the base flange of the rail by being driven thereon in the usual manner. Prior to being applied, its lower leg is entered in the channel l8 so that when applied its said lower leg is disposed in said channel. Its lower leg 20 and the channel l8 are of approximately equal widths. Consequently, when it is applied it is held by the lip l3 against any possibility of moving sidewise relative to the tie plate and thus is rendered particularly effective to resist any tendency of the rail to creep longitudinally.

Preferably the upper face of the channel bottom portion I6 of the lip 13 is spaced downwardly from the bottom of the rail a distance at. least equal to the depth of the lower leg 20 of the rail anchor to avoid any tendency of said lower leg to flex said lip l3 downwardly when the rail anchor is driven onto the rail flange. In this connection there may be a, clearance space between the bottom face of the leg 20 and the upper face of the lip portion l6. Preferably, however, the spacing of the lip portion I6 below the rail is approximately equal to the depth of the leg 20. In any event, the lower leg 20 preferably is provided at its bottom with a downwardly projecting lug 2| and the lip portion [6 preferably is provided with a recess 22 to snugly accommodate said lug when the rail anchor is applied. An interlock thus is afforded between the lip I3 and the rail anchor which effectively holds the latter against creeping outwardly from its operative, applied position relative to the rail flange. In this connection, the interlock afforded by the lug 2| and a the recess 22 may also be depended upon to hold the rail anchor against sidewise as well as against outward movement relative to the tie plate, in which event the lip I3 may be flat and may be devoid of any channel such as the channel I8. Preferably, however, the lug and recess 2|, 22 are used in association with a channel such as the channel I8 as thereby a stronger, sturdier and more dependable structure is afforded.

Of course, a Standard rail anchor may be used in lieu of a rail anchor having a lug such as the lug 2|. If, however, a rail anchor is used having a lug such as the lug 2|, the spacing of the portion I6 of the lip I3 below the rail will be less than the combined depth of the leg 20 and the lug 2| sothat as the rail anchor is driven onto the rail flange the lip It will be flexed downwardly to spring back to its normal position when the lug and the recess become alined to cause the lug to enter the recess and thus provide the said interlock between the lip and the rail anchor.

Obviously, the disposition of the lip I3 beyond a side of the tie II provides for use with the tie plate of rail anchors of either the usual or Stand ard C-type or of the usual or Standard C-type modified to include a lug such as'the lug 2L In either case, the inner end portion of the lower leg 2|] of the rail anchor may be and preferably is, beveled, as indicated at 23, to facilitate initial insertion of said lower leg between the lip I3 and the bottom of the rail.

While tie plates including lips in accordance with the invention may be formed in any suitable manner, one practical method of forming them is first to roll an elongated bar to the desired cross sectional shape of the main body portion Ill, then to out said bar into individual tie plate sections along alternate straight and stepped lines as indicated in Fig. 3 to provide the main body portions It and the lips I3, and then to forge the lip portions I3 of said sections into the channeled form illustrated in Figs. 1 and 2, the recesses or openings 22 being punched or pressed in the portions I6 either prior to or following the forging operations.

As will be apparent from the foregoing, the present, construction affords a simple, inexpensive, practical means of utilizing a tie plate to hold a rail anchor against sidewise movement relative thereto to insure effective functioning of the tie plate in resisting tendency of a rail to creep longitudinally, and also to hold the rail anchor operatively applied to the rail.

Without further description it is thought that the features and advantages of the invention will be readily apparent to those skilled in the art, and it will of course be understood that and then upwardly from the side of the tie plate to provide therein an upwardly opening channel extending longitudinally relative to the tie plate a to accommodate the lower portion of a C-shaped rail anchor to hold the rail anchor against sidewise movement relative to the tie plate.
