RAILWAY-RAIL SPLICE.

SPECIFICATION forming part of Letters Patent No. 349,958, dated September 28, 1886.

Application tiled .Tune 28, 1886. Serial No. 206,462.

T @ZZ whom, it may concern.- l Beit known that I, GHARLEs I. SHARRER, of Syracuse, in the county of Onondaga, in the State of N ew York, have invented new and useful Improvements in Railway-Rail Splices, of which the following, taken in connection with the accompanying drawings, is a. full, clear, and exact description.

rIhis/invention has reference to that class of rail-spliees in which a fish-plate on one side of the meeting ends of the rails has rigidly 'affixed to it lugs or tenons formed dovetail at their extremities and projecting through mortises in the stems ofsaid rails` and a iishplate on the opposite side of the rails is provided with a dovetail longitudinal groove and slipped endwise over the protruding ends of the tenons, and with the latter entered into the aforesaid groove.

In order to permit of tightening the hold of the said tish-plate on the rails, it has hitherto been deemed necessary to make the flanges of the lng or tenon wedge-shaped, and to provide the grooved fish-plate with tapering jaws and ilanges for the purpose of drawing the two fish-plates toward each other and tightening the same against opposite sides of the rails. This Construction, however, is very expensive, as it is difficult to either cast, forge, or swage the plates with their aforesaid tapering or wedging parts, and iu drivingI the groovcd plate so as to tighten it on the tongues or tenons of the other plate the former is liable to be either battered up on the driving end or split longitudinally along the groove, which latter weakens the plate along its longitudinal centrai line.

The object of this invention is to simplify the construction ofthe lislrplates, and to provide cheap, convenient, and effective means for tightening the hold of said plates ou the rails spliced thereby; and to that end my invention consists in the combination, with the rails provided with orifices through their stems, of a straight ishplate on one side of the rails having affixed to it dovetailed tenons formed longitmlinally straight and parallel with said plate, a straight fish-plate on the opposite side of the rails provided with a dovetailed longitudinal groove formed likewise longitudinally straight and parallel with the plate, and a (No model.)

wedge provided with longitudinal slots and inserted endwise between the grooved plate and stems of the rails, all as hereinafter fully described, and specifically set forth in the claim.

In the annexed drawings, Figure l is a side View of my invention. Fig. 2 is a side view of the rails without the splicing-plates. Fig. 3 is a detached isometric view of one of the splicing-plates. Fig. 4 is a transverse section 6o of my invention, and Fig. 5 is a detached isometric view of the wedge by means of which the hold of the splicing-plates is tightened.

R R represent the meeting ends of two rails to be spliced together. The end portions of said rails I provide each with one or more ori frees or mortises, a a, through the stem thereof.

A and B designate the splicing-plates of the species usually denominated fish plates. Both of said plates are perfectly straightlongt 7o tudinally. rIhe plate A, I provide on the side adjacent-to the rails R B with dovetailed tenons f t, distributed over the length of the plate in the same relative positions as the orifices or mortises a a a a of the two rails to be spliced. Said tenons are of such dimensions as to allow them to project th rough the aforesaid orifices or mortises when the plateA is placed against the side ofthe end portions ofthetwo rails. The tenons t tare perfectly straight longitudinally 8o and parallel with the plate A. rlhe plate B,

I provide on the side adjacent to the rails with a longitudinal dovetailed groove, l), which eX- tends through the end of the plate, and is longitudinally straightand parallel with theplate, 8 5 and of proper depth and width to allow the plate to be slipped endwise over the tenonsrl. and closely embrace the top and bottom of the dovetailed portion of said tenons by the top and bottom sides of the groove b, as illustrated 9o in Fig. 4c ofthe drawings. The engagement of the dovetailed groove b with the dovetailed tenons 'f f serves to securely tie the two plates together.

yw denotes a wedge, which is provided with longitudinal slots s s, of greater length than the tenons tt. This wedge I place with its thin end onto the protruding tenons tt before applying the grooved plate B, and after thelatter is slipped onto the tenons I drive the wedge roo from its large end endwise until it becomes secure! y set or fastened in its position, thereby el'l'ectually tightening the plates A and B against opposite sides of the rails. When the wedge is made of steel, I prefer to curve it longitudinally, as shown in the drawings, so as to cause it to act as a spring and guard against excessive strain on the plates A and B when driving said Wedge.

The described {ish-plates I provide with additional holds on the rails and with bearings' on the cross-ties by forming them. with wide ilanges c c, which project from the bottom of the tish-plates and lie closely against the top and side edges of the base of the rails, and terminate lush with the under side of said base. The edge of the ange c, I provide with a notch or notches, through which to drive a spike or spikes into the snbjacent cross-tie. The head of the spike, bearing on top of the flange c, holds the splice firmly on the tie.

I'donotclaim, broadly,the combination,with the rails having orifices through them, of fishplates on opposite sides of said rails and provided with interlocking tongues and grooves, as I am aware the same is not new; Vbut Vhat I do claim as my invention ise The combination, with the rails provided with the orifices a a a a, of the straight plate A, having aflixed to it the dovetailed tenons tt, formed longitudinally straight and parallel with said plate, the straight plate B, provided 3o with the dovetailed groove b, formed likewise longitudinally straight and parallel with the plate, and the Wedge w, provided with the 1ongitudinal slots s s, and inserted endwise between the plate B and. stems of the adjacent 55 end portions of the rails, substantially as described and shown. In tcstimony'whereof I have hereunto signed my naine and affixed my seal, in the presence of two attesting witnesses, at Syracuse, in the 4o county of Onondaga, in the State of New York, this 26th day of June, 1886.

Witnesses:

FREDERICK H. Giens, C. BENDIXON.
