To all whom itmay concern:

Be it known that I, RUFUS VVAPLES, a citizen of the United States, residing in Wayne,

Delaware county, Pennsylvania, have invent-ed certain Improvements in Railway Cross-Ties, of which the following is a specification.

My invention relates to certain improvements in ties made of concrete and to devices for securing the rails to the ties.

The main object of my invention is to improve the form of the concrete tie and prevent the fastenin from becoming loose by securing the rai to the tie some distance from the point of support of the rail, so that the rails cambeleveled without disturbing the ties. s

A further object of the invention is to provide means for'fastening, the rails directly to the ties-where additional security is desired.

In the accompanyin drawings :-Figure 1, is a lon itudinal sectional view of my improved rai way cross tie showing the rails in position; Fig. 2, is a plan view of Fig. 1; Fig. 3, is an enlar ed sectionalview on the line 33, Fig. 1; ig. 4, is a sectional view on the line 4 4, Fig. 1; Fig. 5, is a view showing the method of securlng the tension members of the rails; Fig. 6, is a perspective view of the concrete tie; Fig. 7, is a longia modification of the invention particular y adapted for use at curves; Fig. 8, is a plan view of Fig. 7 Fig.

9, illustrates a modification of the tension member; Fig. 10, is a view of'another modification of the tension member; Fig. 11, is a view of a modification of the tie and means for securing the tie to the rails; Figs. 12, 13

and 14, are perspective views illustrating details of the means for fastening the rails to the tie; and Fig. 15, is a diagram view show- {pg the method of cutting the tension memers.

A is a cross tie made of concrete and reinforced in any suitable manner; this tie has cavities a, a. in its upper surface near each end, as shown in Fig; 6, and a central cavity a all drained in any suitable manner. Mounted in the cavities a, a are the bearing blocks B of wood or other suitable material, and these blocks extend'above the upper surface of the tie as shown in Fig. 1. Supported directly upon these blocks are the rails C, C of any suitable shape.

I), D are metallic .tension members perfos sure to be correct.

rated at their inner ends, in the present instance, for the passage of a transverse bolt 0, and their ends (13 are notched at d, Fig. 15, and shaped to fit over one of the base flanges of a rail. These tension members act to hold the rails in position on the blocks B, B and being properly made the gage of the track If it is found desirable to shift the rails bodily on the tie then the hole in the tie for the reception of the pin 6 is made oblong,.as shown at a by dotted lines (Fig. 2), so that when the pin is properly adjusted the space surrounding the pin may be filled with concrete or other suitable material; firmly securing the rails in position with respect to the tie.

The blocks are preferably mounted between shoulders on the tie, as shown, but this construction may bemodified Without departing from my invention.

The object of placing the securing means at a point some distance from the rails is to prevent the loosening of the fastening means due to the passage of the rolling stock over the rails; and furthermore the rails and the blocks or the rails alone may be raised independently of the tie and filling strips or plates may be inserted between the block and thetie or between the rail and the block to raise the rail when found necessary.

One of the objects of the invention is to so construct the tie and the attaching means that the tie can be properly located upon the road bed and remain permanently in position and if, due to any settling, it is desired to raise the rails then filling strips or plates are inserted between the block and the tie, leaving the tie permanently in position.

The tension members are preferably made, as shown in Fig. 15, from a plate or bar cut in given lengths and each section of plate making two tension members; notches cl; are made in the ends of the tension mem-. here so as to fit the base flanges of the rails, as above described. In order to Secure the tension members firmly to the rails I preferably provide a plate (1 which underlaps the tension member, and has a portion which overlaps the inneinbasc flange of the rail, as shown inFig. 5.

In some instances it is desirable to strengthen the tension members and this can be done, especially on curves as shown in Figs. 7 and 8, by making the tension members double as at D and placing a brace piece (.1 between the two sections and riveting it to the said sections, the brace piece extending under the head of the rail. This member may be placed on the outer rail at the curve so as to resist the lateral strain due to the bearing of the wheels hard against the outer rail. Both sides may be reinforced without departingfrom my invention.

In Fig. 10, l. have illustrated the tension member in a single piece instead of two parts, and having a depending lug which is perforated for the passage of the retaining bolt.

In Fig. 9, I have shown the tension member twisted and bent so that the flat portion will fit under the rail and the bent portion will extend over the outer base flange ot' the rail, in order to give a broad bca ring against the rail.

In Fig. 11, I have shown a tie A slightly different from that of the other figures, the

. blocks B being mounted in the recesses near each end and a flat plate 1) extending from one rail to the other and having each end bent so as to overlap the base flange of the rail and having clips (I which overlap the inner base flanges of the rails; these clips can be secured to the plate l)- in any suitable mannerl This tension member is secured to the tie by a vertical bolt 6 which passes through an oblong recess a." in the tie and when the rails'are in the proper position the space around the bolt can be filled with concrete or other suitable material.

In all the figures above described the securing means for holding the rail in position is situated some distance from the bearing of the rail so that the slight vertical movementdue to the passing of the rolling stock over the tracks will not loosen the tastcniugs, as is now the case and it allows for the ready lifting of the rails without removing the spikes or other t'astening devices to place lmcrs or plates under the rails and without.- having to continuously tamp the roadbed under the ties.

In some instances it may be desirable to secure the rails to the tics iiulepemlentl-y ot' the tension members and this is accomplished by bolts I, as shown in Figs. 1, 3 and 12, having the heads 1' which overlap the inner base flange of the rail and the threads on the bolt 7 mesh with threads in the opening ot' the bar G arranged at an incline, as shown in Fig. 3, and in order to hold the tension memher and, the bolt together I preferably pass the bolt throiwh a loop formed by a strap /1, Figs. 4 and 14 which is formed with flanges It. The tension member is slotted at a point opposite the bolt I and the-body ot' the strap is passed through the slot, the flanges limiting the movement so that the bolt will be held in )osition iiri'espect to the tension member I and yet will be held rigidly to the tie. may pass a key through the slot. '1' in the bolt it desired. to prevent thebolt turnenabledto insert or-withdraw an; bar without removing any portion of the roadbed in which the tie is embedded. \Vhenthe bolts I are used to engage the inner base flange of the rail then the plates (Z are dispensed with and I preferably alternate the plates and the bolts throughout thetraclr.

The blocksB are. slightly narrower than the recess in the tie, so that the tension members and the bolts can be mounted between the l)l0O- and the side walls of the tie, as shown in the drawings.

I claim p 1. The combination of a concrete tie, tear ing blocks thereon for supporting the rails,

with a. tension member connecting said rails 1 and secured to the tie, said tension members consisting of two parts lunged together so as to pernnt of vertical adpistment of the rails.
