RAIL-JOINT;

SPECIFICATION forming part of Letters Patent No. 7 7 2,652, dated October 18, 1904. Application filed June 22,1904. Serial No. 213,623. (No model.)

To all whom it may concern.-

Be it known that I, FRANK FINGER, a citizen of the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Rail-Joints, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has relation to chairs for rails and the like, and has for its object the provision of novel means whereby a section of rail may be firmly held in position upon the ties or the road-bed of a railroad.

Another object of my invention isto providea chair which will be extremely simple in construction, strong and durable, and highly eificient when used, and I have so constructed my improved rail-chair as to allow for the expansion and contraction of the rail-sections and at the same time prevent any lateral movement of the rail-sections mounted within the chair.

Briefly described, my improved chair consists of two members, one member being adapted to be secured to the ties or road-bed and is provided with an integral fish-plate.

The other member is adapted to fit within the first-named member and support the rail-sections therein, this member also being provided with an integral fish-plate, and when the two members are secured together the fish-plates of each member are adapted to support the rail; sections, which are carried within the c 1a1r.

All of the above construction will be hereinafter more fully described. 7 1

Referring to the drawings accompanying this application, Figure 1 is an endviewof my improved chair, showing a rail-section mounted-therein. Fig. 2 is a side elevation of the chair, showing two rail-sections secured therein. Fig. 3 is a perspective view of one of the members comprising the chair, and Fig. 4 is a perspective view of the other member comprising the chair.

, Throughout the several views of the drawings like numerals of reference indicate like parts.

It will be seen that in Fig. 2 of the drawings I have shown two rail-sections mounted within the chair, and it will be observed that one or more ties, as may be desired, and may be made of a sufiicient length tospan these ties; but where it is used only to support the central portion of a rail the chair is made on a smaller scale and is adapted to be supported upon one tie forming the road-bed of the railroad.

The reference-numeral 1 indicates one member of the chair, and 2 the other member. The member 1 consists of the base 3, which upon its edgesis provided with lugs 4:, these lugs being slotted, as indicated at 5 5, whereby the spikes which are commonly used to securechairs of this character upon the ties may readily engage the lugs and firmly hold the chair in. the proper position upon the top of the ties. The other edge of the member 1 is formed with an inwardly and upwardly extending fish-plate 6, this fish-plate being made of such shape as to conform to the contour of the web portions of the rails now used, and in the base 30f the member 1 I form a tapered wedge-shaped slot 7 the entire length of the member, and in this tapered wedgeshaped slot is adapted to fit the tapered wedgeshaped or dovetailed enlargement 8, formed on the under face of the base 9 of the mem ber 2. The one sideof the base 90f the member 2 is provided with an inwardly and upwardlyextending fish-plate 10, which is similar to the fish-plate 6 of the member 1 and conforms to the contour of the rail-sections which are to be mounted within the chair.

When it is desired to secure two rail-sections together or to supporta rail-section upon a tie, the one rail-section is placed upon the base. 9 of the member 2, the fish-plate 10 engaging the web and the'under side of the head of the rail-sections, and this member 2 is then placed in the end of the member 1 and forced inwardly until it has become firmly wedged within said member.

By so constructing my improved chair it will be noted that any tendency of the railsections to move in one direction will cause the one member 2 of my improved chair to become more firmly impinged within the member 1 and that it will be impossible for the rail-sections which have been placed in the chair to become in any manner whatever laterally displaced after the chair has been once secured to the ties.

What I claim is 1. A rail-chair composed of two sections, one section being formed with an integral fishplate, an integral base extending beneath the other section and to the outer edge thereof and being formed with a groove undercut on both sides and tapering from end to end of the section, the other section being formed with a fish-plate and a base, and resting wholly ing formed with integral laterally-extending lugs.

In testimony whereof I aiiix my signati'n'e in the presence of two witnesses.
