RAILWAY METAL-TIE APPLIANCE.

Application filed June 24,

Be it known that we, CHARLES BRADLEY and. THoMAs E. KENNEDY, citizens of the United States, residingat l Vatonga, county of Blaine, and State of Gklahoma, have invented certain newand useful Improvements in Railway Metal-Tie Appliances; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to railway tie plates of the type disclosed and claimed in Patent 1,387,562 to Charles Bradley, issued August 16, 1921. i

It is the object of this invention to pro duce a metal tie that can be substituted for the wooden ties now so extensively employed. As is well known, the wooden tie is liable to become soft, due to rot, and to permit the spikes to slip out or move, and for this reason it is a prolific cause of disastrous accidents.

By the employment of ties constructed in accordance with our present invention, substantially all danger due to the movement of the rails on the tie is overcome. The tie is made almost entirely of metal and therefore does not rot, and as we have provided it with sliding ,plates for holding the rails in place, there is no danger of the rails becoming loose.

In order to more clearly describe our invention, we shall have reference to the ac companying drawing, in which Fig. 1 is a top plan view of our improved tie, parts being broken away to better show the construction;

Fig. 2 is a side elevation of our tie with parts thereof shown in section, taken on line 2-2, Fig. 1;

Fig. 3 is a longitudinal vertical section of a portion of our tie, taken on line 3-3, F s.-

Fig. 4 is a transverse section taken on line 4- 1, Fig. 2; and

Fig. 5 is a bottom plan view of a portion of our tie with the slide plates, anchor plates and ends removed.

The same reference characters will be used to designate the same parts throughout the several views.

In the various figures numeral 1 represents 1922. erial No. 570,545.

the rails of an ordinary railway, and 2 the tie in its entirety. Our improved tie consists of a channel-shaped member of a metal such as soft steel. This member has a bottom 3 and sides 4. The ends of each side of the tie are provided with projecting flanges 5 (Figs. 1 and 5) which serve as guides for the reception of the ends 6, whose sides 7 are provided with channels which cooperates with the flanges 5 to hold in place. The lower ends of sides 7 have notches 8 which cooperate with a corresponding projection on the projecting portion 9. Each end 6 also has an upper flange 10 which projects over the sliding plate 11. Centrally of the tie we provide an anchor plate 12 having downwardly extending flanges 13 which project over and engage the sides 4. A transverse rib 14 is secured to the under side of the anchor plate 12, and extends from the inside of one side to the inside of the other side. A. bolt 15 serves to hold member 1 1 and plate 152- in place on the tie. On each side of member 14 we provide angles 16 which are riveted to the sides 41 and providea slot for the reception of member 1 1. The edges of plate 12 are rabbeted as indicated by numerals 1'7 (Fig. 3). The outer upper edges of sides 1 are provided with outwardly projecting flanges 18 (Fig. 4) which serve as means for engaging corresponding slots in the slidable adjusting plates 11 and 19. The upper edges of the sides of the tie near the ends thereof are provided with notches 20 (Fig. 1) for the reception of the base 21 of the rail 1. Within the ties near the ends thereof are wooden cushion blocks 22 upon which the rails rest; these blocks are of such thickness that they extend slightly above the upper edge of notches 20 so that the bottom of the rail will not touch the metal sides of the tie.

In order to obtain the proper level of the upper surface of the cushion block 22, we provide between the bottom thereof and the bottom of the tie one or more shims 523. The slot 20 is wider than the rail base, so that the latter does not come in contact with the vertical sides thereof. In the left hand end of Figs. 1 and 2, and in Fig. 3, we have shown a rail held in place at points intermediate its ends, and in the right hand end of Figs. 1 and 2 and in Fig. 4:, we have shown how the joints between two rails are formed and how they are clamped to the tie.

The rails 1 are put in place on the tie with the base thereof resting on the cushion block 22. The anchor plate 12 being removed, the sliding elan'ipingplate 19 is put in place and slid over towards the rail, the sides 2 thereof engaging the flanges 18 in the manner shown in F 4:. The anchor plate is then replaced and serves as a rigid abutment tor the clamping plate. The end cover plate '6 being removed, the sliding clamping plate 11 is slid into place and then the end plate 6 is put in place to rigidly hold the same from outward movement. It will be noticed that plates 11 and 19 are each provided with projecting flange 25 which vprojects over the flanged sides of the rail basev The ends of flanges 25 engage the rail web and positively prevent sidcwise movement of the rail. 7

In order to provide for adju tment due to slight variations in the sizes 0 the parts, we provide filler strips 26 oi various widths that can be placed between the outer edge of the adjustable clamping plate 11 nd the end cover 6. On the ties where the joints come, we provide sliding plates 11? 19 which are slightly modified for the purpose of accommodating the fish plates 53?. In order to insulate the rail from the ties so that they may be used for signalling purposes, we provide suitable insulating means, such as fibre sheets 28, between the rai and the metal parts of the tie, the cushion block being provided wi h transverse channels 29 for the reception of the lower ends of the insulating members, The cushion blocks 22, being made of wood, are good insulators and they, together with members 28, serve to completely insulate the rail from the tie. Theouter end or" each block 22 has verse channel 30 which accommodates the bolt '31 and permits adjustment of the bloelt. The anchor plate is of such width that when it is removed plates 19 and 19 may he moved inwardly a suflicient distance to r ease the rail. Anchor plate 12 and sliding clamping plates 19 are so proportioned as to width that they serve ,to properly space the rails. The bottom of our ties is provided with projections 32 which engage the roadbed and prevent sliding of the tie.

From the above description it will appear that/we have invented a standard metal tie that is provided with means for adjusting itto the rails, and which also permits the rails to be thoroughly insulated from the tie,

Having now described our invention, what we claim is 1. A; metal tie for railways, comprising a channel-shaped body member having outwardly projecting flanges on the ends of each. side, an end cover plate provided with grooved sides for the reception of said ,ianges, the upper edges of each side being provided with outwardly projecting flanges, clamping plates slidably connected with said flanges, notches in the upper sides near the ends of the tie, and an anchor plate rigidly secured to the central portion of said tie and cooperating with the sliding clamping plates to prevent movement of the latter.

2. A metal tie for railways, comprising a channel-shaped member, an anchor plate removably connected to the tie substantially midway between the endsthereof, a notch in the upper edges of each side near the ends, outwardly projecting flanges on said sides on each side of the notches, a sliding clamping plate on each side of the notches, said plat-es having means -for engaging the flanges of a railway rail, and means on the end of the tie for preventing outward movement of the outer clamping plates.

3. A metal tie for railways, comprising a channel-shaped member, an anchor plate removably connected to the tie substantially midway between the ends thereof, a not-ch in the upper edges; of each side near the 'ends, outwardly projecting flanges on said sides on each side of the notches, a sliding clamping plate on each side of the notches, said plates having means for engaging the flanges of a railway rail, means on the end of the tie for preventing outward movement of the outer clan'iping plates, and cushion blocks in said tie near the ends thereof.

4, A metal tie for railways, comprising a channel-shaped member, an anchor plate removably connected to the tie substantially midway between the ends thereof, a notch in the upper edges of each side near the ends, outwardly projecting flangeson said sides on each side oi the notches, a sliding clamping plate on eachsideof the notches, said plates having means'forengaging the flanges of a railway rail, outwardly projecting flanges on the end of each side, a cover having grooves cooperating with said lastnamed flanges and provided with means for preventing the outward movement of the outer sliding plates, and cushion blocks within said channel-shaped member.

In testimony whereof we afliX our signatures. v
