T() ALLl WHOM IT MAY CONCERN:

Be it known that I, E. G. PATTERSON, of Pithole City, in the. county of Venango, and State of Pennsylvania, have invented a. new and useful Improvement in Rail-Joint or Coupling; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming apart of this specification. i

Figure 1 is a side view of the contiguous ends of twondjacent rails'to which my improved coupling has been attached. A

Figure 2 is a detail sectional view ofthe same, taken through the line a: 2:,Vg. I.

Figure 3 is a detail sectional view of the same, taken` through the line y y', iig. l.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved coupling or joint for the rails of railroadtracks, which shall be so constructed as to securely connect the ends of the rails to each other, without weakening the seid rails by the formation of bolt-holes, and in such a. manner that the said ends may receive a steady straining support; and it consists in the construction and combination of various parts of the coupling, as hereinafter more fully described.

A and B are the adjacent ends of two contiguous rails.

C are the fish-plates or bars, which extend along 'the sides of the ends A and B of the rails, between' the top and base anges of said rails. The inner sides of the ish-plates C. may be hollowed out, so that they may bear onlyagainst the top und base iunges of said rails, und their outer sides are made sloping, or iuclining outwards, as shown in figs. l and 2.

D is the chair, which is placed directly beneath the joint between the ends A and B of the rails.

The inner surface of the upwardly-projecting jaws d1 of the chair inclines outward, and enters inclined notches in the bottom flanges of the rails A and B, and in'the lower parts of the outer or sloping sides of the fish-plates C, us shown in iig. 3, so that the pressure of any weight upon the ends A and B of the rails may force the said rails and fish-plates more closely-together, by forcing them further down between the inclined jaws of the said chair. l

The bottom of the chair D rests upon the middlle part of the wooden bars E, which said bars E are kept from lateral movement or displacement by the lips d2, formed upon the ends of the under side of the chair D, and which overlap the sides of the said bars E.

F are the clamps, which clasp the inclined or sloping outer sides ofthe {ish-bars or plates C, and the.inner sides of' thejaws of which are hallowed out, so that they may not bear against the edges of the bottom Bauges of the rails A and B. I

G are bolts, the heads of which are squared, and countersunk in the bottom plate of the clamps F, as shown -in dotted lines in iig. 2, and which pass through holes through the ends of the bar E`when said bar is made in one piece, and through notches in the adjacent sides ofthe bars E when made in two parts or pieces. The'bars E are held in place by washers and nuts, H, placed upon the lower ends ofthe said bolts G. By this construction the tslrplates C carry the weight, and 'are the'main support to the ends of the rails, the choir, clamps, wooden bnrs, Sic., being designedl primarily to keep the fish-plates or bars securely in place.

If the iish-plates C should yield, a depression at the Weak point, which is the joint of the rails, forces the said plates C more firmly into the chair D, causing the said iish-plates to hug the rails more closely,v

The pressure exerted upon the chair D is communicated Aby the elnsticwooden bars E to the clamps F, causing the said clumps to more firmly bind the lieb-plates C.

The wooden bars E being screwed up', by means'of'the bolts Gr and nuts H, to a. steedystraining-point, the rails obtain their steady aid in supporting the load upon the fish-plte,making the coupling :ict as a. truss.

It should be observed that loosening the nuts H, so that the bars E may be. free from the lips dz., yallows the seid bers E to be removed, when the clamps F may be easily yslipped from the ends of the sh-pltes, and the chair D and fish-plates C may be conveniently and easily detached without in the least disturbing the rails.

Having thus described Vmy invention, what I claim as new, and desire to secure by Letters Patent, is- 1. The chair D,- made with the inner sides of its jaws Ainclined or wedge-shaped, substantially as herein shown and described, and for the purpose lset forth. I

2. The clamps F, constructed as described, and provided with bolts G and nuts H,`in-combination with the fish-plates C, by which they are supported, and With the Wooden bar or bars E, which they support, substantially as herein shown and described, and for the purpose set forth.

3. The combination of the sh-plates C and chair D .with each other and with the ends A and B of the rails, substantially as herein shown and described, to form a rigid support for the said ends of the said rails.

4. The combination of the sh-plates C, chair D, wooden bar or bars E, and clamps F with each other and with the ends A and B of the rails, substantially as herein shown and described, and for the purpose set forth.

E. G. PATTERSON.
