RAILROAD-TIE.

SPECIFICATION forming part of Letters Patent No. 592,907, dated November 2, 1897.

Application filed December 5, 1896. Serial No. 614,638. (No model.)

.To aZZ whom it may concern: I

Be it known that I, ELIJAH B. GILPIN, a citizen of the United States, residing at Davis, in the county of Tucker and State of West Virginia, have invented certain new and useful Improvements in Railroad-Ties; and I do hereby declare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it appertains to' make and use the same.

This invention relates to improvements in railway ties or sleepers and means for securing rails thereto.

The invention relates to certain novel constructions, combinations, and arrangements of parts, all of which will be hereinafter more particularly set forth and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 represents a perspective view of one'of my improved ties with sections of rails applied thereto. Fig. 2 represents a top plan view of one of my improved ties, the rail and rail-fastenings being removed. Fig. 3 represents a vertical section taken through one of my ties, with the rails attached, on the line of the rail-clamps. Fig. 4 represents a transverse vertical section through one of my improvedsleepers, and Fig. 5 represents a transverse vertical section through my improved sleeper.

A in the drawings represents the sleeper; B B, the rails; O, the rail-clamps, and D the locking-springs. The said sleeper A comprises a horizontal plate (1, preferably constructed of metal, a vertical Web a, formed along the under side of said plate, centrallyarranged bracing-brackets aiconnecting said web and horizontal plate, and horizontal beads or flanges a formed along each edge of the under side of said plate a. The horizontal plate forms a support for the rails, while the vertical web a braces said plate and prevents tipping of the same. The brackets a prevent longitudinal movement contacting with the ballast. The heads a strengthen the edges of the plate a and also assist in preventing the rocking of said plate. Elongated slots a are formed in said plate a to receive the rail-clamps 0. Each of these clamps comprises a shank 0, having a head 0, formed with an incline 0 upon one side,'adapted to engage the flange of the rail. Said shank c is also provided at its lower end with an offset 0 After the rail has been applied in position the shank and ofiset o are passed of the plate C6 by through one of the elongated slots at. The shank o is then given a quarter-turn, so as to bring the inclined surfaceof the head 0 upon.

effectually holds the clamp in position and prevents'its being moved to disengage it from the rail. When it is desired, though, for any reason to remove said clamp, this is accomplished by simply removing the spring at upward with a suitably-shaped tool and then givingsaid clamp a quarter-turn to bring the ofiset c in alinement with the slot a when said clamp can be withdrawn upward.

By the employment of my invention the rails are held firmly in position against any accidental displacement and at the same time are so secured that they may be instantly removed, if desired, by simply removing the clamp C, as before described. The lower ends of the bow-springs D are preferably turned out slightly, as at d, so as to effectually prevent any accidental displacement of said clamp.

By means of the peculiar mounting of the clamps for the rails in the elongated slots the rails are rendered free to expand and contract because of the varying temperature without in any wise afiecting the ties upon which the rails are resting.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination with a railway-sleeper having a horizontal plate provided with elongated slots, and a vertical web formed on the under side ofsaid plate, of rail-clamps each provided with a head at each end and adapted to be passed through the elongated slots and given a square turn to' lock them in contact with said plate and the flange of the rail, and loopsprings having concave portions and adapted to be applied in the elongated slots to prevent the rail-clamps from turning, the concave portions of said springs engaging the walls of the slot to hold said springs in position, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

ELIJAH- B. GILPIN.
