This invention relates generally to a composite railroad tie or stringer and more particularly to a cross tie ofthe non-insulated type which is'adapted to be embedded in the concrete of a street or road in such a manner that the top of the rail is disposed substantially level with the surface of the street or road.

The main object of the invention is to pro- I videca simple, durable and efficient rail sup-J port which is made of; few partswhich are readily assembled and disassembled and which is well adapted to qu ntityproduction at comparatively lowcostr A further object of the invention is to provide a cross tie construction which consists A still further obJect ofthe invention is to provide a strong and dependablecross 'tie construction in which the angle barsare bent upwardly at the central portion thereof and disposed in a plane considerablyabove 'the end portions thereof'whereby to reinforce the upper slab of concrete between; the rails.

A still further object of the invention is to provide a cross tie construction of thecharacter described in which the cross angle bars are bent upwardly between. the rails so as to require less concrete between the rails and which is also provided with means for securelyanchoring the rails to the central portion of the cross bars. j

' invention will appear as the description proceeds and by reference to the accompanying drawing in which Fig. 1 is a top plan view of my improved tie construction Fig. 2 is a view inside elevation of the tie shown in Fig. 1; Y 'Fig'. 3 is a view in end elevationof the tie shown in'Figs. 1 and 2 but on a smaller scale;

Fig 4 is a vertical-sectional view of aportion of a roadbed having my; improved tie arranged therein and Fig. 5 is a viewsimilar thereof so as. to reinforce the upper slab of fspaced'para'llel angle bars or cross beams.

"plates 5 and 6 which fit withi'n the slots as f plates are secured in place they will be dis- .preferably have portions 9 and 9? out thereneath the raiIs'are'SOmeWhat deeper-than the Further and more limitedobjects of the remainlng portion; The tles are assembled to F ig. 4 disclosing a modified form of'tie construction in which the central portionsof the angle bars are deflected'upwardly and disposed in aplane abovethe end portions concrete between the rails. p

' 'Referring now to the drawings thereference characters 1 and 2'designatea pair of The. opposite ends of the angle bars 1 and 2 and disposedat opposite ends thereof are rail shown most clearly in Figs. 1 and 2. The rail plates 5' and-6are preferably welded to the angle bars, as shown most clearly in Fig. 2. The railplates 5 and 6 are eachjprovided with oppositely disposed pairsof'T-shap'ed slots 7, 8 andfl7 8*. These slots are adapted toreceive the rail clamps therein for securing rails to the railplatesin a mannerto be here,- inafter described. The slots 3, 3 and 4.14 T are. cut on slight angle so that when the rail posed ata slight angle to each other so that when the rails are secured thereto they will slope inwardly slightly in orderto conform to the contourof they wheels. The rail plates from and bent downwardly... therefrom as shown, which portions'serve to firmly embed the tie in the concrete. Thetie maybe shipped in the disassembled or. .knock-fdown condition soas to occupyv less space in shipping and may be assembled at thetrack side or at any other convenient place. e i

In forming the road bed a trench is provided in which the portions immediatelybeopenings 12 and 13'. After'thi's layer of'con 100 to I are providedwith slots 3, 4 and 3 4* respectively. Connecting the angle bars 1 and2' drain ofi below the foundation.

' filled with bituminous concrete indicated at 14: in Fig. 1. This material consists of'slag and crude asphalt in about the following proportions: 3 parts fine slag, 2 parts coarse slag and 1 part crude asphalt. This material is waterproof and prevents water from seeping in adjacent or along the rail. The drain holes arefilled with gravel or cinders or other suitable material which permits the water to It is of course understood that drain holes may be provided along'one or both sides of the rails.

In Fig. 5 there is disclosed a slightly modis fied form of my invention. This form of the invention is substantially identical with the form of the invention shown in Figs. 1 to 4 inclusive except that the central portions of the angle bars or cross beams are bent upwardly so as to be disposed in a plane above the end portions thereof. The rail plates are secured to the angle bars as described in connection with Figs. 1 to l inclusive. Disposed adjacent the opposite ends of each of the angle bars are tie rods 15 and 16. The inner ends of the tie rods are preferably welded to the central port-ion of the angle bars as shown at 17 and 18. The opposite ends of the tie rods are threaded and are adapted to project through openings in the rails and to be secured thereto by nuts-19, 20 and 19 20*. These tie rods serve to strengthen and reinforce the construction as a whole and to firmly secure the rails against displacement. According to the preferred construction the central portions of the angle bars are disposed in a plane about two inches above the end portions thereof.

This construction enables a thinner layer of concrete to be used between the rails and provides a reinforcement for the comparatively thin upper layer of material. It also effects a saving of concrete amounting to approximately 350 cubic yards per mile which at present prices will amount to about $3,000.00 per mile.

'Various changes may be made in the details of construction and in the manner of assembling and securing the various parts in 7 place without departing from the spirit of my invention. Moreover, it should be understood that my invention is not' limited to any particular type of road surface or foundation as different materials may be used according to the nature of the track and according to the load the trackis intended to withstand. It is therefore understood that my invention is limited only in accordance with the scope of the appended claims.
