RAILROAD-TRACK srnncrnnn;

Applicatioaled April 12, 1926. `Sierizil No; 101,260.

The present invention relates to railroad tracks and especially to railroad l tracks wherein the ties are formed from metal, each tie being characterized bythe fact that comprises two rolled bars, such as for example, tivo lengths of Worn track rail, fastened. rigidly in spaced relation to each other, `and providing rectangularopeninffs spaced so as to be located at each sidentF tom flanges of the track rails, such openings being taching the rails to the metal tie.

At the points between rail lengths,` is; necessary to provide splice bars for fasten-i l 4ing the rails together, and the object of my present invention is to provide an improved construction and arrangement of fastening means for fastening a rail to the metal tie at points where splice bars arelocated.

For a consideration of what `I believe to` be novel and my invention, attention is d1-` i'ected to the accompanying description and the Vclaims appended thereto.

` In the drawing, Fig. 1 View, partly in section, of a construction em-` bodying my invention, the arrangement be` ing adapted for use with `Wide splice bars;

Fig. 2 is a sectional view ofthe construction shown in Fig. 1, and Fig. 3 is a view similar to Fig. 1 of a .midified form `of fastening means adapted for use with narrow splice bars. j l

Referring to the drawing, `the track tie illustrated comprises two lengths of Worn rail `5 and 6 `connected together at their ends by angle bars 7. Extending trans` versely of Worn rail lengths 5 and 6 are tie plates 8, one adjacent to each end of the tie, the same being located in positions such that thebase flanges of the track rails rest on them. In each tie plate 8 are rectangular slots or openings U9 adapted to receive rail .s fasteners, the openings being spaced apart a held `in place by bolts 13. `In Figs. 1 and:

distance such that they are on opposite sides ofthe rail base flange. s l i 10 and 11 indicate ends of adjacent track rails connected together by splice bars 12 2, wide splice bars are shown and `it Will be seen that their lower outer edges 14 project over slots or openings 9.-

For fastening the rails andfsplice `bars to the tie, I provide fasteners each compris-- ingtwo members 15 and 16, which are clamped to the edge of the tie plate by a bolt 17. Member 15 has a lip 18 which proiiiliiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiliiiiliilliiiliillililllilillumina the botapted to receive fasteners `for `at-` is a perspective jects into opening 9 anda second lip 19 which stands :in spaced relation to the edge of plate 8. Lip `18 serves to` anchor member 15 against sidewise movement. Lip 19 serves to provide with the edge of plate 8 a socket 2O.` Member 16 has a lip2l which depends into socket 20,` thus interlocking `with lip 19, avertical surface 22 which engages the edge of the splice bar and a nose`23 which projects over the top surface of the splice bar. When members 15 and "lare clampedto the edge `of tie plate 8 by holt 1,7, they are held rigidly .in place against movement in any direction and present to the splice bar the tiXed `vertical surface 22 and the nose which serve to hold the rail in position. Surface 22and `nose 23g however, `do not clamp tightly the edge of the splice bar but have preferably,` a small amount of clear ance to permit of a Wave action in the rail due to heavy loads passing over it Without subjecting members 15 and `16` to excessive stresses. i l j i The members 15 and 16, it Will be seen, are of rolled rectangular' sectionfivhich means that they can be manufactured at lou7 cost. 'They may be made by being out from long bars rolled tothe required section.

Between the rail and the tie is an insulatinar member 24e-.comprising a laminated metal structure, `the laminations being insulated` from each otherfin suitable manner.

It will `be seen that lip 19 of member 15 cooperates with the edgeoftie plate S to form a` socket 20 which in substance and when viewed from one aspect, may be considered` as providing a slot of the nature of slot 9 except that it is spaced further from thetrack rail flange g and it is this sl ot which receives the track railfastening means and servesto hold it against sidcwise movement. The bolt 17 cooperates With tie plate 8 to hold the `track rail fastening means against ATENT OFFICE.

p bers having a part which leo opening 9. Fastener 30 has a shoulder 32 which engages the top surface of tie plate 8 and a hole 33 in which is located a keeper 34. Fastener 31 has a shoulder 35 which engages the top surface of tie plate 8 and a hole 36 in which is located a keeper 37.L Keepers 34 and 37 are driven in under tie plate 8 and serve to hold fasteners 30 and 31 firmly in position. Fasteners 30 and 3l have noses 38 which project over the splice bars and serve to fasten the track rail to the tie after the manner explained already in connection with the construction shown in Figs. l and 2. With the construction shown in Fig. 3, fastener 30 may be first put in place, the track rail then forced over against it after Which fastener 3l is put in place. As will be. noted in connection with this con-V struction also, fasteners 30 and 31 and keepers 34 and 37'are of rectangular section which enables them to be manufactured at ow cost in that they may be cut from rolled ars.

In accordance With the provisions of the patent statutes, I have described the principles of operation of my invention, together with the apparatus which I now consider to Vrepresent the best embodiment thereof, but
