RAIL SUPPORT.

Application filed July 13,

This invention relates to certain new and useful improvements in composite railroad stringers and ties and more particularly to cross ties of the insulated type. y

The main object of the invention is to provide a simple, efiicient and durable rail support which comprises few parts which are so interlocked with each other as to impart great strength and rigidity to the entire structure.

Another object of the invention is to provide a generally improved cross tie construction of the character described which is made up of a steel skeleton frame, the several parts of which are made of standard materials capable of being produced at any properly equipped steel mill, and so constructed that the tie may be put together, either at the mill or at the track side and the concrete filling placed in position after the skeleton structure of the tie has been put in place.

Another object of the invention is to provide a cross tie construction which will not become buckled or broken as a. result of heavy loads passin overthe rails and which will not become center bound.

A still further and important object of the invention is to provide a cross tie construction wherein a maximum support is given to each rail and lateral deflection of the rails is prevented and in which the two rails are allowed a limited up and down movement independent of each other. 7

Further and more limited objects of the invention will appear as the description proceeds and by re erence to the accompanying drawing in which Fig. 1 is a top plan view of my improved tie with the rails secured thereto; Fig. 2 is a vertical sectional view on the line 2-2 of Fi 1; Fig. 3 is a vertical sectional view on t e line &3 of Fig. 1; Fig. 4; is a vertical sectional view on the line 44 of Fig. 1; Fig. 5 is a perspective view of one of the blocks to which the rails are secured; Fig. 6 is a top plan view of the skeleton frame as sembled; and Fig. 7 is a view in side elevation of the skeleton frame.

Referring now to the drawing in which like parts are referred to by the same'reference characters, the numerals 1, 2, 3 and 4 designate plates which form a partof the skeleton frame and which are shaped as shown most clearly in Figs. 4, 6 and 7. These plates are preferably made of steel and have portions 5 cut out therefrom and bent as shown most 1927. Serial No. 205,340.,

clearly in Figs. 4, 6' and 7 the purpose of which Wlll hereinafter appear. The plates 1, 2, 3 and 4 are secured together and held in spaced relation with respect to each other by means of spaced, parallel, transversely extending cross beams 6-which extend through slots in the opposite ends of the plates 1, 2, 3 and 4. The cross beams are preferably channel shaped in section and welded to the plates so as to hold the same against displacement. It will also be seen that the outer plates 1 and dare slightly inclined so that water will be drained off and away from the tie. This inclination of the outer plates also serves to strengthen that portion of the tie on which the rails rest.

By an inspection of Figs. 1 and 2, it will be seen that the plates are so spaced that the distance between the plates 2 and 3 is greater than the distance between the plates 1 and 2 or 3 and 4. The skeleton frame when assembled appears as shown most clearly in Figs. 6 and 7. The skeleton frame is placed in a form and concrete is poured in to fill the spaces between and adjacent the plates. The bent portions 5 interlock with the concrete and serve to reinforce and strengthen the entire structure. Before the concrete is poured wedge shaped blocks are positioned between the plates 2 and 3 and spaced apart. These blocks serve to provide a pair of wedge shaped openings 7 and 8 on each side of the completed cross tie. lVhen the concrete has hardened and set. the form and the blocks are removed. ledge shaped blocks 9 and 10, one of which is shown in detail in Fig. 5, are then positioned within the opening 7 and 8. These blocks 9 and 10 fit neatly within the openings 7 and 8 as shown 1n Fig. 3 and rest loosely therein. The tie plates 11 rest on the top of blocks 9 and 10 and the rails 13 and'lt are fastened to the blocks by means of spikes 15 which extend throughthe tie plates and into the wooden blocks. It will thus be seen that the rails may have an up and down movement independent of each other and that there will be no lateral deflection of the rails. It will also be clear that due to the shape of the openings and blocks the strain will be equally distributed over a comparatively large area.

The skeleton frame may be shipped in a disassembled or knocked down condition and may be assembled atthe track side. The bot-- tom edges of the completed tie are inclined 'my invention to scribed comprising a plurality upward slightly as shown in Figs. 2 and at. This inclination of the outer edges of the tie permits the ballast 7) to be readily tamped around and under the tie.

It will be clear that I have provided a tie or rail support which accomplishes the objects of the invention as hereinbcfore stated. Various changes may be made in the details of my construction without departing from the spirit of my invention. For example, the blocks 9 and 10 may be made of metal or reinforced concrete, instead of wood, and the flanges 1, 2, 3 and 4 as well as the cross beam 6 may be of different shape. I therefore wish be limited only in accordance with the scope of the appended claims.

Having thus described my invention, what I claim is 1. A rail support of the character dcof spaced parallel plates extending parallel with the track, parallel cross beams extending transversely of the track and connecting said plates and holding the same in spaced relation, concrete filling the spaces between said plates, bearing blocks disposed between two of said plates and resting loosely therebetween, a tie plate carried by each of said bearing blocks and means for fastening a rail to said bearing blocks.
