RAIL-JOINT.

SPECIFICATION formingpart of Letters Patent No. 691,525, dated January 21, 1902.

Application filed May 23, 1901. Serial No. 61,540. (No model.)

To a/ZZ whom, t may concern:

Be it known that I, SHERMAN BLAIR, a citizen of the United States of America, residing at McKeesport, 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 relates to certain new and useful improvements in rail-joints, and relates more particularly to that class wherein the use of nuts and bolts is entirely dispensed with.

The present invention has for its object the provision of novel means whereby interlocking fish-plates are employed that will form a substantially rigid rail connection; furthermore, to provide novel means whereby the expansion and contraction are provided for in this class of joints.

This invention has for its still further object to construct a rail-joint of the above class that will be extremely simple in construction, strong, durable, and comparatively inexpensive to manufacture.

With the above and other objects in view the invention consists in the novel combination and arrangement of parts to be hereinafter more fully described, and specifically pointed out in the claims.

In describing the invention in detail reference is had to the 'accompanying drawings,

forming a part of this specification, and wherein like numerals of referenceindicate corresponding parts throughout the several views, in which- Figure l is a side elevation of a portion of two rails having attached thereto my im'- prcvements. Fig. 2 is a top plan view thereof. Fig. 3 is a longitudinal sectional view taken through the web of the rail immediately below the tread. Fig. 4 is an enlarged perspective view of one of the interlocking fish-plates. Fig. 5 is a similar view of the other interlocking fish-plate. Fig. 6 is a cross-sectional view taken on the line 6L (i of Fig. 2.

In the drawings the reference-numeral l indicates the rails, which are of the ordinary construction. In the end of theiweb are formed openings 2. On each side of said openings are formed through the web enlarged openings 3 3.

The reference-numeral 4 represents one of the interlocking fish-plates, carrying on its one face an inwardly-extending projection 5, which projection is seated in the recesses 2 2 of the web of the rail. The said interlocking fish-plates carry on each end projections 6, extending into the openings 3 3.

The reference-numeral 7 indicates the oppositeinterlocking fish-plate carryinghooked ends 8,whicl1 hooked ends also extend through the openings 3 3 and engage the end of lthe outer face of the fish-plate 4, forminga locking connection therewith. These hooked ends 8 are formed of spring-steel or the like in order that they may be given a wedging action as they are driven in place and will spring n proper position to engage the outer face of the fish-plate 4, thereby forming a locking connection therewith.

9 denotes a base-plate,which may be formed integral with one or both of the locking fishplates and adapted to extend beyond the base of the rail. This base-plate is secured to the ties in any suitable manner.

The many advantages obtained by the use of my improved rail-joint will be readily apparent from the foregoing description, taken in connect-ion with the accompanying drawings.

It will be noted that various changes may be made in the details of construction without departing from the general spirit of my invention.

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

1. Ina rail-joint, the combination of two interlocking fish-plates, one of said sh-plates carrying projections on each end and extending through the web of the rail, the other of said fish-plates carrying a pair of hooked portions one on each end extending through the Web of the rail andiengaging the outer face of said 'rst-named fish-plate, substantially as described.

2. In a rail-joint, the combination of two interlocking fish-plates, upper and lowerengaging faces on said {ish-plates, projections made integral with one of said fish-plates eX- tending through the web of the rails, hooked IOO plate carrying hooked portions extending through the web of the rail and engaging the outer face of the first-named fish-plate, all parts being arranged and operating substantially as described.

4. In a rail-joint, a sh-plate, upper and lower beveled engaging faces thereon, projections made integral with said fish-plate y extending through the web of the rail, a second fish-plate, a base secured thereto, upper and lower beveled engaging faces thereon, hooked portions made integral with said shplate extending through the web of the rail and engaging the outer face of the firstnamed fish-plate, substantiallyas described.

5. In a rail-joint, the combination of a baseplate, a fish-plate made integral therewith, upper and lower engaging faces on said fishplate, hooked portions carried by said lishplate on each end thereof, a second sh-plate, upper and lower engaging faces thereon, projections carried by said fish-plate, the said hooked portions adapted to engage the outer face of said second-named iish-platc, substantially as described. A

In testimony whereof I aflx my signature in the presence of two witnesses.

SHERMAN BLAIR.
