ADJUSTABLE RAIIPFASTENER.

Specification of Letters Patent.

Patented Nov. 7, 1911.

Application med April 1, 1911. Serin no. 618,337.

To all whom it may concern:

Be it known that I, JAMES B. POPE, a citi i zen of the United States, residing at San Francisco, in the county of San Francisco l and State of California, have invented new l and useful Improvements in Adjustable Rail-Fasteners, of which the following is a specification.

rIhe object of the present invention is to provide an improved fastener for railroad rails, which can be applied, by suitable adjustment, to various sizes of rails.

It is intended principally for use with concrete ties, but may also be used with ties of other material.

In the accompanying drawing, Figure l is a broken longitudinal section of a concrete tie, showing in cross section a base plate, and a rail secured thereon by my improved fastener; Fig. 2 is a broken plan view of said rail and base plate.

Referring to the drawing, 1 indicates a concrete tie of any suitable construction, 1.

Upon

formed with vertical apertures 2. said tie rests a rectangular base plate 3, formed at its ends with upwardly extending flanges 4, and also formed with vertical apertures 5, adapted to register with the apertures 2. Upon the ends of said base plate rest bearing plates 6, each having in its under surface at one side thereof a recess 7 adapted to lit snugly against the corresponding flange 4 of the base plate. The upper surface of said bearing plate slopes upwardly outward at the same angle as the upper surface of the corresponding side of the flange 8 of a rail 9, which flange rests on said base plate between the two bearing plates.

The inner edge of each bearing plate is formed with a central recess 10, which, when the bearing plate is in position, registers vertically with the apertures 5 and 2 in the base plate and tie respectively. Upon each bear-- ing plate, and upon the corresponding portion of the flange of the rail, rests the clamping plate 11, the under surface of which slopes upwardly outward, on each side to correspond with the upward slope of the upper surfaces of the bearing plate and the flange respectively. Each clamp plate is formed with holes 12 elongated in a direction transverse to the rail, and adapted to register vertically with the recess 10 and with the apertures 5 and .2 on the same side of the rail. Through said apertures 2 and 5,

f recess 10, and elongated hole 12 on each side is passed upwardly a bolt 13, and upon the l upper end of the bolt extending above said clamp plate is screwed a nut 14 which may be, if desired, provided with a loclmut of any standard or approved construction. It will `readily be seen that by screwing down said nuts the rail is secured very firmly in position.

An important feature of my invention consists in the fact that my improved fastener can be used without change of parts for various sizes of rails by a mere adjustnient of the clamp plates. I have in Fig. 1 shown in full lines a 90 lb. rail and in dotted lines a '60 lb. rail, and I also have shown in dotted lines the positions of the clamp plates for use with the lighter rail. It is seen that for a light rail it is only necessary to move the clamp plates down upon the upper surfaces of the bearing plates, so that the inner inclined lower surfaces of the clamp plates contact with the inclined upper surfaces on the flange, and, having so adjusted the clamp plates, to screw the nuts on the bolts so that they fit tight on the clamp plates.

l. The combination with a rail having flanges, a support for said rail, clamp plates the under surface of each of which slopes upwardly outward on both sides, the inner upwardly sloping portions of said surfaces engaging flanges of the rail, means, sup ported by said support, and having -upwardly and outwardly sloping upper surfaces adapted to be engaged by the outer surfaces of the clamp plates, and means for securing said clamp plates and support together, substantially as described.

2. The combination with a rail having flanges, a support for said rail, clamp plates the under surface of each of which slopes upwardly outward on both sides, the inner upwardly sloping portions of said surfaces engaging flanges of the rail, said clamp plates having elongated holes, means, supported by said support, and having upwardly and outwardly sloping upper surfaces adapted to be engaged by the outer surfaces of the clamp plates, bolts passing upwardly through said supports and clamp plates, and nuts on the upper ends of said bolts, substantially as described.

3. In combination with a rail having flanges, a support for said rail having at its ends upwardly extending flanges parallel to said rail, bearing plates on said support adapted to lit snugly against said latter flanges, the upper surfaces of said angle plates being inclined upwardly outward, clamp plates on the anges of the rail and upon said bearing plates, and means for securing said clamp plates, bearing plates, and support together, substantially as described. Y

4;. In combination with a rail having flanges, a support for said rail having at its ends upwardly extending flanges parallel to said rail, bearing plates on said support adapted to fit snugly against said latter flanges, the upper surfaces of said angle plates being inclined upwardly outward, clamp plates on the flanges of the rail and upon said bearing plates, the support and clamp plates having vertical apertures, bolts through said apertures, and nuts screwed upon said bolts, substantially as described.

5. yIn combination with a rail havingflanges, a support for said rail having at its ends upwardly extending flanges parallel to said rail, bearing plates on said support adapted to fit snugly against said latter flanges, the upper surfaces of said bearing plates being inclined upwardly outward,

clamp plates on the flanges of the r'ail and n upon said bearing plates, the surface of each clamp plate being equally sloped upwardly outward at each side, and means for securing said clamp plates, bearing plates, and support together, substantially as described. v 6. In combination with a rail having flanges, a support for the rail having at its ends upwardly extending portions, bearing plates on said support each having a part adapted to be engaged by said upwardly extending portion to prevent movement thereof, the lianges and bearing plates having equally inclined upper surfaces, clamp plates, the lower surface of each being inclined on each side upwardly at the same angle of inclination as the corresponding bearing plate and flange of the rail, bolts passing through said support and clamp plates, and nuts on the ends of said bolts, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
