RAILWAY SPLICE-BAR.

SPECIFICATION forming part of Letters Patent N 0. 395,924, dated January 8, 1889.

Application filed May 31, 1888.

10 all whom it may concern: Be it known that I, GEORGE P. ROSE, a citii zen of the l nited States, residing at Fenton, county of Genesee, State of Michigan, have invented a new and useful Railway Splice-Bar, of which the following is a specification. This invention relates to the joints and splice-bars of railways; and it has for its object a novel construction of the splice-bars, I whereby greater strength is secured and the bolts which secure the splice-bars to the rails are carried with the rails in their contraction and expansion, the bolt-holes through the rails being the size of the bolts instead of i elongated, as heretofore.

In the drawings forming a part of thisi specification, Figure l is a perspective view; Fig. 2, a cross-section, enlarged, on line 3 3 in Fig. 1; Fig. 2' a cross-section on line 2 2 .1 in Fig. l, enlarged; Fig. a, an enlarged perspective of a part of the splice-bar; Fig. 5, a perspective of a portion of the splicebar; l ig. o, a perspective of a lettered detail, hereinafter described; and Fig. 7 is aside elevation of the rails at the joint.

Referring to the lettered parts of the drawings, B are the rails with square ends at the joint. Each rail has a slot, '0, in the end, so that when the rails are together end to end, as in Fig. 7, there is an elongated hole between, and partially in each rail, as at r in Fig. '7. The splice-plates are provided on the inside with a boss, c, Fig. 4., of a size to fit the slot 1'. Fig. 3 shows these parts cfitting in the slot r from both sides. Thus by means of the boss on each splice-bar the rails are greatly strengthened at the joint, and less strain comes on the flanges of the splice-bars, and less dependence need be placed upon the 5 bolts. The holes through the rails are the size of f the bolts. All the holes through the splicebars are as shown at a, Fig. 4f The boss of the washer A fits into the hole. a, but are I less in size longitudinally than the holes a, i and the bolt-hole through the washers is the size of the belt, for which reasons when the rails contract and expand the washers slide in the holes a, because the bolts are carried l with the rails and the washers with the bolts. The washers A on one side are screwthreaded in their bolt-hole, and the threaded I ends of the bolts r, Fig. 2, are screwedl Serial No. 275,557. (No model.)

through them, and a lock-nut, u, is screwed onto said threaded end of thebolt and against the washer A, Fig.

Having thus described the invention, what I claim as new, and desire to secure, is-

1. The combination of the rails having the holes the size of the bolts, the washers provided with the boss, the splicebars having the slots longer than the boss on the washer, and the securing-bolts, substantially as set forth.

2. The combination of the rails having the end slot and bolt-holes the size of the bolts, the splice-bars having the central boss, and the slots to receive the washers, the washers having the boss of a length less than said washer-slots, and the securing-bolts, substantially as set forth.

3. The combination of the rails having the bolt-holes of a size to just receive the bolts,

the splice-bars having the washer-slots, the washers having the boss of a length less than said slots, the holes in the washers on one side of the rail being screw-threaded, and the bolts having the screw-threaded ends in said screw-threaded holes, substantially as set forth.

4. The combination of the rails having the bolt-holes of a size to receive the bolts, the splice-bars having the washerslots, the washers provided with the boss of a length less than said slots, the holes in the washers on one side of the rail beingscrew-threaded, the bolts having the screwthreaded ends in said holes, and the lock-nuts on the extended ends of the bolts, substantially as set forth.

5. The combination of the rails having the end slots and bolt-holes, the splice-bars provided with the central boss and having the i washer-slots, the washers provided with the boss of a length less than the washer-slots, the washers on one side of the rail havin their bolt-holes screw-threaded, the bolts having the screw-threaded ends in said holes, and the look-nuts, substantially as set forth.

In testimony of the foregoing I have hereunto subscribed my name in presence of two wi tn esses.
