JOHN L. GASH AND SAMUEL L. MCDAVITT, OF ELMER, MISSOURI.

CONTINUOUS LAP-JOINT AND NUT-LOCK.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed. September 12, 1907. Serial No. 392,602.

To all whom it may concern:

Be it known that we, JOHN LEWIS GASH and SAMUEL L. h'lcDAvITT, citizens of the United States, residing at Elmer, in the county of Macon and State of Missouri, have invented a new and useful Improvement in Continuous Lap-Joints and Nut-Locks, of which the following is a speciiication.

This invention relates to rail-joints, the object being to provide a lap joint which will decrease the jar and noise caused by the wheels moving over the same.

Another object of our invention is to provide a very simple and effective device of this character which will securely hold the meeting ends of the rail together, and one which will reduce the wear of the rolling stock passing over the same.

A further object of our invention is to provide very novel means for locking the nuts of the joint so that all danger of the saine working loose is prevented.

A still further object of our invention is to provide a rail joint which is exceedingly simple and cheap in construction, and one which will securely lock the rails together and prevent the same from spreading.

lilith these objects in view, the invention consists in the novel features of construction, combination and arrangement of parts, hereinafter fully described and pointed out in the claims.

In the drawing forming a part of this specification: Figure l is a top plan view of our improved rail-joint. Fig. 2 is a side elevational view of the same.- Fig. 3 is a section taken on line 3 3 of Fig. 1. Fig. 4t is a section taken on line 4--4 of Fig. l, and Fig. 5 is a detail perspective of a portion of the locking bar. l

In the drawing A and B indicate railsections having their meeting ends cut ob- .liquely forming beveled tongues which are provided with square ends forming a joint which will decrease the jar as the train passes over the same. The joint is placed on a chair-plate C adapted to rest on a couple of ties and is provided with a central notch C in one edge, in which a down wardly projecting tongue D of an angled fish-plate D is adapted to lit, the fish-plate resting up against the web of the j oint-rails and being provided with a series of spaced openings, through which bolts are adapted to pass through the oint and through a fishplate E arranged on the other side, the said plate being provided with openings registering with the openings of the first men.-k

tioned plate, and having slots E formed in its base for the purpose hereinafter fully described. The heh-plates are securely locked together by nuts working on the bolts and the 'fish-plates are locked on the chair by spikes which pass through notches formed in the edges of the chair into the ties, the head resting on the base of the fish-plates and securely locking the chair on the ties.

Arranged on the fish-plate E is an angled locking bar F which is provided with downwardly projecting tongues F2 which fit in the Slots formed in the fish-plate E and is provided with a series of notches Fl adapted to lit over the nuts of the bolts and prevent the same from turning after they have been tightened, the locking bar being securely locked on the fish-plate by a screw Gr and it will be readily seen that after the islrplates have been securely lockedon the sides of the meeting ends of the rail-sections, thelocking bar can be readily secured thereon so as to securely lock the nut, and it will also be seen that by unscrewing the screw it can be read ily lifted off.

From the foregoing description it will be readily seen that we have provided a railjoint which is so constructed that the parts can be readily detached so as to place the meeting ends of the rails in place thereon, and one which is very strong and durable so that all danger of the rails spreading at the joints is prevented.

Having thus fully described our invention, what we claim as new and desire toV secure by Letters Patent is l. A rail joint comprising a chair-plate having a notched edge, fish-plates arranged on said chair, one of said fish-plates being provided with a tongue adapted to iit in said notch and the other with spaced slots, and an angled locking bar arranged on the fishplate With the slots provided with tongues fitting in said slots, for the purpose set forth.

2. In a rail joint, the combination with a chairplate having a notched edge, of railsections having interlocking ends, arranged on said chair-plate, fish-plates arranged on said chair-plate against the webs of the railsections and secured thereto by bolts, one of said {ish-plates being provided with a tongue fitting in the notch of said chair, and the other with slots, and an angled locking bar provided with a series of notches to receive provided with tongues fitting into said slots, and having a series of spaced notches adapted to fit over the nuts of the bolts, and means for locking said angle-bar on said 15 the nuts of said bolt arranged on the fishplate With the slots having tongues projecting into said slots, and secured thereon by a screw, for the purpose described.

5 3. In a rail joint, the combination with a plate, for the purpose described.

chair-plate of rail-sections having beveled JOHN L GASH interlocking tongues arranged on said chair, S L M015 AVITT' fish-plates arranged on said chair and bolted to said rails, one of said iisli-plates being lVitnesses:

10 provided With spaced slots, and an angled E. B. WHITMAN,

locking bar arranged over said fish-plate R. D. WHITE.
