Specification of Letters Patent.

Patented Apr. 20, 1915.

Application filed December 22, 1914. Serial No. 878,615.

To all whom it may concern Be it known that 1, SUN R. STILL, citizen of the United States of America, residing at Hot Springs, in the county of Garland and State of Arkansas, have invented certain new and useful Improvements in Railway- Ties and Clamps, of which the following is a specification.

This invention relates to railway ties and clamps and comprises an improvement upon the structure shown in Letters Patent 1,097,373 granted to me on the nineteenth day of May, 1914:. v

The structure shown in the present in 5 vention has for its object to efliciently secure the rails to the ties and to render it unnecessary to employ any fish-plates at the joints of the rails.

Further objects and advantages of the invention will be set forth in the detailed description which now follows:

111 the accompanying drawing, Figure 1 is a partial perspective view of a railway tie and clamp constructed in accordance with the invention and Fig. 2 is a longitudinal sectional view of the tie, with the associated parts in position.

Like numerals designate corresponding parts in both of the figures of the drawing.

Referring to the drawing the numeral 5 designates the tie which may be either solid or hollow, though preferably it is made hollow as shown. Rail receiving recesses 6 having the undercut walls 7 and 8 on the opposite sides thereof are formed transversely of the tie and these recesses receive the base portions of the rails and certain peculiarly constructed wedges which serve the double function of fish plates and of clamping elements to hold the rails in position upon the tie. The rails comprise the substantially triangular base portion 9, web 10 and ball portion 11. The inner side wall of the recess 6 conforms to the shape of and closely engages the adjacent face of the triangular base portion 9 of the rail. A wedge 12 is driven into position between the opposite faces of the rails and the undercut wall 8 of the recess 6. This wedge tapers in two directions, that is it tapers lengthwise but it also has a tapered portion 13 vertically considered. It will be noticed by referring to Fig. 1 that the portion of the wedge which engages the undercut wall 8 tapers to nothingness at the small edge of the wedge.

The wedge above its point of engagement with the tie, is continued to form a part 1 1 which is of sufiicient height to extend to and engage the web of the rail and to bear against the under side of the ball portion of the rail so that fish-plates may be dispensed with. Transverse fastening devices such as bolts 15 are carried by the wedges and serve as set screws to bind against the rails and to thereby bind the wedges against endwise movement, after they are once driven into position, the expense of fish plates is avoided and the rails are securely held together upon the tie without the use of spikes or like fastening devices.

When it is deflected that in a single mile of track a great many fish-plates have to be used, and a great many spikes driven into position, the desirability of providing such a construction as is herein shown and described will be readily apparent.

While the elements shown and described are well adapted to serve the purposes for which they are intended, it is to be understood that the invention is not limited to the precise construction set forth, but includes within its purview such changes as may be made within the scope of the appended claims.

Having described my invention, what I claim is:

1. In a device of the character described the combination with a tie having a transverse rail receiving recess formed entirely across its upper face and having the opposite side walls of said recess undercut, of rails having substantially triangular base portions seated in said recess with one side of the base portion thereof engaged with one of the un dercut walls of the recess, a wedge disposed between the opposite side of the rail and the other of said undercut walls said wedge tapering both longitudinally and vertically and being of such height as to extend from the base of the recess to the underside of the ball portion of the rail, and a fastening device traversing said wedge and arranged to bind against one of said rails to thereby hold said wedge against movement.

2. In a device of the character described the combination with a tie having a transverse rail receiving recess formed entirely across its upper face and having the opposite side walls of said recess undercut, of rails having substantially triangular base portions seated in said recess, With 911?) Side of the base portion thereof engaged with one of the undercut Walls of the recess, a Wedge disposed between the opposite side of the rail and the other of said undercut Walls said Wedge tapering both longitudinally and vertically and being of such height as to extend from the base of the recess to the underside of the ball portion of the rail, and a set screw threaded through said Wedge and arranged to bind 10 against one of said rails to thereby hold said Wedge against movement.

In testimony whereof I afiix my signature in presence of two Witnesses.
