METAL RAILROAD TIE.

Application filedJune 16, 1927. Serial No. 199,289.

My invention is an improvement in metal railroad ties and relates more especially to that type in which the tie is-formed from a rail, preferably a T-rail, bent upon itself at its ends to provide loop portions for increas ing the bearing of the tie in the roadbed and having wooden blocks seated in the loop portions to rest upon the inwardly projecting base flanges and provide resilient seats and insulation for the rails as well as the means for securing the rails to the tie by means of the usual spikes.

The principal object of my invention is to provide a metal railroad tie of this general type which is of a particular construction to increase the stability of the tie without n1a terially adding to the weight of the same, and in connection with the improved form of metal tie I employ a wooden block at each end thereof which ismore securely held in place and more effective in insulating the rails from the metal tie.

\Vith these principal objects in view my invention consists in forming a metal railroad tie from a T-rail having a reinforcing flange at the upper end of the upstanding portion thereof, said reinforcing flange ex tending inwardly with respect to the bent end portions or end loops of the tie for oooperation with a particular form of wooden block seated in the end loops and extending above the tie to receive the rails, in the present instance the wooden block cooperating with the end loop of the metal tie to have sntlicient bearing thereon for firmly supporting the rails and insulating them from the metal tie; all'as hereinafter fully described and particularly set forth in the appended claims.

In the accompanying drawings:

Figure 1 is a plan view of a metal railroad tie constructed in accordance with my invention.

Fig. 2 is an enlarged plan view of an end portion of the tie, the block being removed.

Fig. 3 is a sectional view on the line 38 of Fig. 2.

Fig. 4 is a plan view with the block and railroad rail in place.

Fig. 8 is a plan view illustrating a modifi- Fig. 5 is a detail side elevation of the block cation of the wooden block used in connection with the tie. g

My invention is carried out in connection with that particular type of metal railroad tie in which a metal bar or T-rail 10 is bent upon itself at its ends to form loops 11 for increasing the hold of the tie in the roadhed and provide the required bearingfor the railroad-rails supported either directly thereon or on wooden blocks seated in the loops on the base flanges; but in the present instance the upstanding portion 10 of the T- rail or tic, which rises from the opposite base flanges 10 10, is provided at its upper edge with a laterally projecting flange 12 for the p urposc of increasing the rigidity of the tie and more particularly to cooperate with the blocks hereinafter described upon which the rails 13 are supported. In bending the end portions of the rail to form the loops 11 the aforesaid flange 12 projecting at one side of the upstanding portion 10 of the T'rail or T-beam 10 is disposed at the inner side of the loop or bet-ween the opposite parallel members thereof. i

To more effectually support the rails 13 on the bent ends or loop portions ofthe metal tie hereinbefore described I provide a particular form of wooden block 15, shown in detail in Fig. 5, which closely fits within the loop portion 11 between the upright members thereofand rests on the adjoining inner base flanges 1O 10, said block having a groove 16 around the side of thesame to receive the inwardly projecting flange 12 and having the upper portion 15 thereof extended laterally to overlap thetop of the tie including the flange 12, whereby the block not only has a bearing on the base flanges but also bears on the upper surface of the tie to provide an additional hearing as well as more effectually insulate the railroad rails from the metal tie.- The tie is secured in place by bolt 17.

The railroad rails 13 are supported on the blocks 15, with a plate 18 interposed be tween the rail and block, and are secured in place by means of the usual spikes 19.

Instead of having the block 15 extend all the way into the loop portion of the metal tie, as shown in Figs. 1, 4 and 6, I may use a shorter block, 20, as illustrated in Fig. 8, and of course in this instance the block is held in place by one or more bolts, the important feature of both forms of blocks being to have the upper portion thereof above the metal tie extend over the top of the rail for the purposes hereinbefore ex plained.

From the foregoing description in connection with the accompanying drawings it will be obvious that I provide a metal railroad tie having a wooden support for the rails to give the desired resiliency and properly insulate the railroad rails from the metal tie. the particular form of block employed to serve these purpo:e.\ being securely locked in place against vertical movement as well as providing a wide bearing for the railroad rails thereon.

It will he umlm'stood that the blocks are set in place by sliding them longitudinally into the loop portions 11 ot the tie from the inner end ot said loops. and as they are locked. in place by the flange. 12 engaging the groove 16 only a single bolt is required tor holding them in place. The metal plates 18 reduce the wear on the blocks resulting from the rolling stock pasaing over the rails. and of course at any time a block may be readily replaced at little expeme. the main portion of the tie being of metal and therefore very durable.

I elaim:

1. In combination with a metal railroad tie having loops at its ends and base flanges within the loops. of a hloclc for the loop end of the tie fitting hetween the side members of the loop and having laterally projecting upper end portions overlying the upper edge of: the body portion of the tie.

In combination with a metal railroad tie having loops at. itsv ends and ha e flanges within the loops. of a bloel; for the loop end of the tie fitting in the loop agaiiol the curved portion thereof and enlarged laterally atv its upper portion to overlie the upper edges of the side members of the loop.

3. In combination with a metal railroad tie having loops at: its ends and base flanges within the loops. ot' a reinforcing lateral flange at the upper edge of the body portion of the tie. and a wooden block for the loop of the tie having a groove in ita sides to receive the reinforcing tlange at the upper edge of the tie and having its upper portion projecting laterally over the upper edge of the tie to seat on said flange in addition to the seating of the block on the base flange.
