CONCRETE RAILWAY-RAIL TIE.

Specification of Letters Patent.

Patented May 26, 1908.

Application filed September 26, 1907. Serial N0, 894,610.

T 0 all whom it may concern:

Be it known that I, CHARLES L. RUsE, a citizen of the United States, residing at Milford, in the county of Kosciusko and State of Indiana, have invented certain new and useful Improvements in Concrete Railway- Rail Ties; and I do declare the following to be a full, clear, and exact description of the invention, reference being has to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to railway-rail ties that are composed of'metal and plastic material hardenedand adapted to support and tie the rails of railways, the invention having reference particularly to composite ties in which metal bars are embedded in plastic material, the invention relating also to devices for fastening the rails to the ties.

The objects of the invention are to provide a relatively inexpensive composite rail tie which may be constructed largely of concrete and be adapted to yield at either end portion under the rail without liability of fracturing the concrete between the two rails, and to provide an improved. concrete tie which will be adapted to positively-gage and secure the rails to the tie to the end that durability and economy may be attained.

The invention consists in a railway rail tie comprising two concrete end blocks and a plurality of metallic tie bars, each embedded in the two concrete blocks, and binding bolts locking the tie bars and'end blocks together and servingalso in securing the rails to the tie, and the invention consists further in the novel parts and combinations and arrange-- ments of parts as hereinafter particularly described and defined in the appended claims.

Referring to the drawings Figure 1 is a top plan of the improved tie on which are fragments of a pair of railway rails and secured thereto; Fig. 2, a longitudinal vertical sectional view taken centrall of the tie and transversely of'the rails; Fig. 3, a transverse sectional view of the tie approximately on the line A A in Fig. 2; 4, a perspective 'view of one of the binding bolts; Fig. 5, a fragmentary side elevation of the tie and a rail thereon shown in transverse section; Fig. 6, a fragmentary top plan of the main tie bar of the tie; Fig. 7, a fragmentary top plan of the tie; Fig. 8, a fragmentary side eleva- Fig. 10, a plan view of one of the body tie bars.

of the tie.

Similar reference characters in'the different figures of the drawings designate like elements or features of construction.

Practically embodied, the improved tie comprises two end blocks a and a, each one of which is rectangular in cross-section and 'of suitable width and height, both being approximately of equal length, each one being of sufficient length to support one rail and extend suitable distances at either side of the rail, ends I) and I) being placed one near the other with a suitable space 0 between the ends, which space is approximately at the middle of the length of the whole tie, being between the two rails, the opposite ends 11 and d of the end blocks respectively being the extremities of the complete tie outside of the rails. The end blocks may be composed of cement and other suitable material,such as sand and gravel or broken stone and formed in a plastic state in a suitable mold. A body tie bar 6 of rolled bar iron or steel is out off of suitable length to reach from end to end of the complete tie and near one end portion has two square bolt holes f and f, and in the other end portion it has a 0 two square bolt holes 9 and g to receive binding bolts, and obviously additional bolt holes may be provided if desired. A main tie-bar his also em ployed which is provided with a pair of opposing shoulders i and i. on the top near one end thereof and also opposing shouldersj and j on the top near the opposite end thereof for gaging the rails, and at opposite sides of the shoulders are suitable bolt holes lc'and 7; that register with the holes in the body tie bar. Also another body tie-bar Z is preferably provided that is a counterpart of the with the upper surfaces thereof, so that the shoulders stand up slightly higher than the upper surfaces of the end blocks.

A suitable number of-binding bolts as m and m and another pair a and n are employed, all of the bolts being identically alike, each bolt having a square body portion and a square head 0, each bolt having a nut thereon and a pin hole g in the threaded end clamp has a bolt hole t therein through which a binding bolt extends, each clamp having a shoulder u at the under side thereof to engage the edge of the rail flange and inclined under face o to bear upon the top of the rail flange.

. of the gage shoulders thereof, and a pair of the clamps as will be seen, are secured against the rail flanges and also against the top of the tie-bar by the nuts of the binding bolts, so that the binding bolts not only secure the different parts of the tie together, but also fasten the rail to the tie i It will be understood that when the rails become worn out they may be readily replaced by new rails, and in case the main tiebar becomes corroded and unfit for use, owing to exposure to the elements, it may be removed from its seat in. the concrete end blocks and a new tie-bar may be readily substituted therefor, and also the binding bolts may be driven out and replaced by new ones if required, while the remainder of the .tie may last indefinitely, the body tie-bars being ordinarily protected against exposure to the atmosphere by the ballast of theroad bed which will fill the space 0, so as to cover the tie-bars and also cover the ends of the body tie-bars.

In practical use, the tie will be slightly flexible at its middle portion, so that if the ballast permits either end portion of the tie to settle under the weight of the passing trains, either end block may settle slightly without causing fracture of the concrete material, the tie-bars being slightly flexible, and either end block may be slightly raised when resurfacing or le eling the track without disturbing the level of the other end block of the tie, it being understood of course that the ballast is tamped under the end portions of the tie only, and not under the middle portion therelhe rails w and 10 rest upon the top of the main tie-bar 71, each rail between two of. When loads are on the rails the downward pressure will be disturbed upon the concrete portion and the tie-bar portion of the tie so that the whole width of the top of the tie sustains the loads. i

Having thus described the invention, what is claimed as new is- 1. In a railway rall tie, the combniation of two concrete end-blocks spaced a minute distance apart, a flat body tie-bar almost en- I tirely embedded fiatwise in the lower portions of the end-blocks with a middle portion only of the tie-bar exposed between the endblocks to be covered by road ballast, the end portions of the tie-bar having square boltholes therein, ,a main tie-bar arranged above the body tie-bar and bedded in the tops of the end-blocks flush therewith and having on each end thereof two opposing gage shoulders extending up beyond the upper surfaces of the flatwise in the end-blocks with middle portions only of the ti'e-bars exposed between the end-blocks to be covered by road-ballast, the end portions of the tie-bars having registering square bolt-holes therein, a main tiebar arranged above the uppermost body tiebar and bedded in the tops of the end-blocks flush therewith and having on each end thereof two opposing gage shoulders extending up beyond the upper surfaces of the tie-bar and the block, the main tie-bar having boltholes therein registering with the bolt-holes of the body tie-bars, and square bolts in said bolt-holes and embedded in the end-blocks with heads engaging the under side of the lowermost body tie-bar, said 'bolts having each a nut thereon and a hole in its end to receive a cotter, substantially as shown.

In testimony whereof, I affix my signature in presence of two witnesses, on the 14th day of September, 1907.
