:METAL RAILWAY TIE .AND AIL FASTENER.

Application filed muy 17, 192e. serial n. 652,130.

To @ZZ whom t may concer/rr.' Y

Be it known that I, WARREN SMITH, a citizen of the United States, residingat Los Angeles, in the county of Los Angeles and VState of California, have invented certain new and useful Improvements in Metal Railwayv 'flies and Rail Fasteners, of which the following is a specification.

This invention relates to metal railway ties and rail fasteners, and has for one of its objects to simplify and improve the construction Yand increase the efficiency and utility of devices of this character.

Another object of the invention is to provide an efficient means for clamping the rails to ties, and adjustable to fit rails of various sizes.

Another object of the invention is to provide a device of this character having simple means for insulating the rails from the tie structure.

Y With these and other objects in View, the invention consists in certain novel features of construction as hereinafter vshown and described and then specificallypointed out in the claims, and in 'the drawings illustrative of the preferred embodiment of the invention.

Figure 1 is a side Velevation of the confronting ends of a pair of railway rails and a pair of the improved ties in transverse section and the coupling means between the ties and the rails in end elevation.

Fig. 2 is a plan View of the parts shown in Fig. 1.

Fig. 3 is a section on the line 3 3 of Fig. 1.

Fig. 1 is a sectional view illustrating the manner of applying the improved device to the rails and ties intermediate the ends.

Fig. 5 is a perspective view of the body or chair member of the coupling member, detached, for one side of the track, and

Fig. 6 is a like view of the chair member for the other side of the track.

Fig. 7 represents the insulating plates in perspective and detached.

The improved device includes a tie member 10 of the usual length, about eight feet, and the usual width, from eight to ten inches, and formed with a plurality of corrugations longitudinally, as represented in Fig. 1.

Riveted or otherwise attached as at 11 to the tie where the rails are located is a support or chair member each formed with an upwardly directed intermediate portion 12 and outwardly directed flanges 13 to reyand chairs 12, 13, are spaced from the confronting ends ofthe rails in the usual manner.. The usual clamp or fish bars areV represented Vat 16 and coupled to the rails by the usual clamp bolts 17.

Formed through each of the portions l2 of each chair near their diagonally opposite corners are slots 18, the slots extending partly into the vertical sides and partly into the horizontal top Vof the chair, as shown more clearly in Fig. 5, and also formed in each vertical wall near the other diagonally opposite corners are apertures 19.

A tie bolt 20 is extended respectively through each of the apertures 19 and the slots 13 and each formed with a hook 21 at one end to pass through the slots and engage over the outer portions of the clamp plates 16, and provided with nuts 22 at the opposite end bearing against the adjacent portion of the chair as illustrated more clearly in Fig. 3.l

By this means the rails are firmly coupled to the chair members and any degree of tension may be applied by operating the nuts 22, as will be obvious, so that a perfect line and gage may be maintained as the rails wear, and by the same nuts 22 and bolts 20.

The hooked bolts provide simple and effective means for adapting the device to varying widths of rail flanges, and the hooks 21 will be of ample strength to withstand any strains to which they may be subjected.

When the improved devices are employed in electrically operated signal systems, the chairs which are located between the ends of the rails will be insulated from the rails by plates of non-conductive material indicated at 23, and will be in two parts, exactly alike so that they are interchangeable as shown in Figures 4 and 6, so that they can be inserted from opposite sides between the rails and chair members and will be notched as shown at 24 to receive the hooks 21 to prevent displacement or creeping When the improved device is employed for holding non-electrified rails, where the insulating plates are not required, the hooks 21 will engage directly over the flanges of the rails, as will be obvious.

The line of ballast will usually come about two and one half inches below the flanges of the rails as indicated by the broken line 25 in Figures 3 and 4.

The slots 16 will be arranged in diagonally opposite relations at opposite sides of the track, as indicated in Figures 5 and 6, the chair member for the right hand rails being represented in Figure 5 and the chair 'for the left hand rail in Figure G, so that the pull on the bolts 2O caused by the eXpansion and contraction will not pull the ties into a diagonal position.

The improved device is simple in construction, can be manufactured of any required weight, to withstand the strains to which it will be subjected when in use, by the rolling stock.

VThe preferred embodiment of the invention is disclosed in the drawings and set forth inthe specifications, but it will be understood that modifications within the scope oit the claims may be made in the construction without departing from the principle of the invention or sacriiicing any of its advantages.

Having thus described the invention, what is claimed as new is l. A railwayrail fastener comprising a chair member including an intermediate portion with vertical sides and horizontal top and adapted to be rigidly attached to a railway tie, said intermediate portion having diagonally opposite slots, each slot extending into boththe vertical sides and horizony tal top, and diagonally opposite apertures in the vertical sides, tie bolts extending through said apertures and provided respectively with, hooked terminals extending through said slots and adapted to bear over the flanges olf railway rails from opposite sides, and clamp nuts engaging said bolts and bearing against the adjacent vertical portion of the chairs.

2, The combination with Va railway rail joint including clamp plates attached to the confronting endsof a pair o'l' rails, of chair members, each including an intermediate portion with vertical sides and horizontal top and adapted to be rigidly attached to railway ties, said intermediate portion having diagonally opposite slots, each slot eX- tending into both the vertical sides and horizontal top, and diagonally opposite apertures in the vertical sides, tie bolts extending through said apertures and provided respectively with hooked terminals extending through said slots and adapted to bear over the :flanges of the rails Jfrom o osite sides flanges of railway rails from opposite sides,

clamp nuts engaging said bolts and bearing against the adjacent vertical portions of the chairs, plates of non-conductive material inserted between the rail and chair member 'fram opposite sides and with inturned outer portions bearing over the flanges of the rail and engaged by the hooked terminals of the tie rods.

In testimony'whereof, I aiix my signature hereto.

WARREN SMITH.
