TIE-PLATE.

Application filed December 24, 1914.

To all whom it may concern:

Be it known that I, EDMUND B. Pownns, a citizen of the United States, residing in the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improvement in Tie-Plates, of which the following is a specification.

The invention relates to the flat plates in terposed between the railway rail and tie, secured to the latter and supporting the rail, and the object of the invention is to provide a plate which may be economically manufactured, adapted to support the rail and be fastened to the tie and resist reliably the lateral strains on the rail, and also shaped to receive a wedging member eo-acting with the base-flange of the rail to hold the latter against longitudinal movement or creep relatively to the plate and tie.

The invention consists in certain details of construction by which the above objects are attained, to be. hereinafter described and claimed.

The accompanying drawings form a part of this specification and show an approved form of the invention.

Figure 1 is a plan or face View of the improved tie-plate. Fig. 2 is a side elevation. Fig. 3 is a longitudinal section, taken on the line 3-3 in Fig. 1. Fig. 1 is an end View.

Similar letters of reference indicate the same parts in all the figures.

The plate is designed to be cheaply manufactured by a rolling process and comprises a main body portion A preferably plane on the under face and having openings a a and a a to receive spikes or other fastening means, not shown, by which it is secured to a tie beneath.

Transversely of the plate near one end extends an abutment or ridge B having a plane vertical face adapted to receive the outer edge of the base-flange of a rail, indicated in dotted lines, and hold the rail reliably against outward movement.

The abutment is of less height at its ends, or at the sides of the plate, to permit the spikes to be driven with their heads in close engagement with the base-flange, and the openings a a for the reception of the spikes extend inward beyond the inner face of the abutment so that the spikes will bear directly against the base of the rail, which latter extends within said openings, the

spikes bearing against the base of the rail on one side and against the outer wall of the spike openings upon the opposite side, thus transferring the strain directly to the tie plate and greatly lessening the tendency of the spikes to work loose. On the opposite end of the plate is a lug C forming the central portion of a corresponding ridge G 0 having vertical faces located at a little distance from the inner edge of the base-flange. The spike holes a a on this side, or end of the plate, are located between the ridge 0 G and the base-flange so that the ridge serves as an abutment for the outer portions of the spikes and reinforce and hold them in engagement With the base-flange. As will .be seen clearly from an inspection of Figs. 2

and 1, the ridge portions C G of the lug O are of less height than the central portion so that the spikes may be readily driven through the spike holes a a and yet these ridges serve to materially brace and strengthen the raised central portion as well as forming abutments for the spikes.

The inner faces 0 c of the lug C are vertical and inclined inwardly at a slight angle from-the center of the lug toward the baseflange so as to form therewith angular spaces adapted to receive a suitable member shaped to be wedged or crowded toward the narrow end of either of such spaces by frictional engagement with the edge of the baseflange and one of the faces on the abutment, and when thus wedged to hold the rail reliably against further movement or creep relatively to the tieplate.

The wedging member is indicated in dotted lines as a roller M having a head or flange M lying in a shallow recess A formed in the upper face of the plate and extending beneath the rail at one side and into a rebate or groove 6 at the base of the lug C, but the member may be of any form adapted to engage frictionally the edge of the base-flange and the adjacent inclined face of the lug and be forced along the angular space thus provided, until further movement is impossible and the rail and tieplate are thus interlocked.

I claim:

1. As an improved article of manufacture, a tie plate comprising a body portion having at one end a transverse abutment extending substantially throughout the width of the tie plate to engage the outer edge of the baseflan'ge of a rail, said abutment havingcspike openings extending through the same and through the body portion, said body portion having at the opposite'end a transverse lug comprising a raised central portion and side ridges of less height, said raised portion having, vertical faces inclined to form an obtuse angle one With the other and extendlng angularly'in opposite directions, said body portion having spike open- *sameand:- through 'thebody,- portion, said body-portion having at the opposite enda transverse lug -"compr1sing; a: ra1sedcentral portior iand side rid'ges' of less-height, said raised 'portion havingvertical faces inclined to -form an-obtuse angle one With the other extending angular'ly in opposite directionsy; saidiwl'ugextending substantially throughoutthe-entire Width of'the body portion and the said bodypor'tion having-spike openings: therein extending beyond-the inner face of the lug and through the body portion.

3. As an improved article of manufacture, a tie platecomprisinga body portion having at one end a transverse abutment extending substantially throughout thc'width of the tie plate to engage the outer edge of the base flange of a rail, said abutment having spike openings extending through the same and through the body portion, said body portion having at the opposite end a transverse lug comprising a raised central portion and side ridges of less height, said r-aised portion having vertical faces inclined to form -an obtuse angle one with the other and extending angularlyinopposite directions, said lug extending substantially throughout the entire Width of the body portion With its central portion raised and itsinner faces upon opposite sidesofsaid inclined faces substantially parallel with the inner faces of saidv abutment;
