TROLLEY WIRE SPLICER Filed Aug. 25, 1935 INVENTOR M MMM) Patented Sept. 1, 1936 UNITED STATES PATENT OFFICE 2,053,160 TROLLEY WIRE SPLICEB Karl J. Mosebach, Pittsburgh, Pa. Application August 23, 1935, Serial No. 37,516

2 Claims.

My invention relates to splicers for trolley wires, and has for one of its objects the provision of a splice member of such form that it can readily be assembled on adjacent ends of trolley wires, and the wires conveniently fastened therein, in a tautened condition.

Another object of my invention is to provide means on a splicer for bringing the adjacent ends of the spliced wires into alignment with one another, but offset in relation to the main body portion of the wire, and maintaining them in that position, thereby to prevent loosening or slippage of the wires relative to the splicer.

Still another object of my invention is to provide a splicer of such form that a hanger clamp may be conveniently attached to the end portions of the spliced wires.

In the accompanying drawing, Figure 1 is a plan view of a splicer, with a trolley wire hanger connected thereto; Fig. 2 is a side view thereof; Fig. 3 is a longitudinal sectional view of the splicer showing parts at an intermediate stage of assembly, and Fig. 4 is a view taken on the line IV--IV of Fig. 2.

The splicer is shown as applied to the ends of

trolley wires

5 and 6. The splicer is in the form of a casting or forging I of suitable material, such as brass or the like. The splicer near its ends is of enlarged cross section as shown at 8 and 9, and holes are provided in these enlarged ends for the insertion of the ends of the

wires

5 and 6.

In applying the splicer to the two wires or to the two broken ends of a wire, the wire 5 may first be inserted as shown in Fig. 3, whereupon a set screw 9 will be turned to clamp the wire firmly in place. A second set screw Ill will then be turned to bend the extremity of the wire 5 to the position shown in Fig. 2. This bending effect results from the fact that the bottom walls of the holes lie in angularly-disposed planes which meet at the points H with the bottom wall of a groove l2. The screw I0 is disposed over the horizontal groove I l, and will therefore force the ends of the wire downwardly into the groove l2 which extends along the upper side of the splicer 1.

The end of the wire 6 will then be drawn through the other end 9 of the splicer until it and the splicer 1 have been placed under the desired degree of tension. Thereupon a set screw I3 is turned down to securely clamp the wire 6 to the splicer. The excess in length of the wire 5 6 is then sawed or cut ofl'f at M. Thereupon, a screw l5 will be turned downward to force the extremity of the wire 6 into the groove l2, and into parallelism with the adjacent end of the wire 5, as shown more clearly in Fig. 2. The end portions of the

wires

5 and 6 are therefore held in offset relation to the body portion of the wires and prevents slippage of the wires in the splicer, even though the screws l0 and I5 should be somewhat loose.

The parts are then in position where they may be grasped by a hanger clamp l6 which may be of any ordinary construction, and whose jaws I1 will be forced into the grooves in the sides of the

wires

5 and 6.

It will be understood, of course, that it is not necessary to apply a hanger to the ends of the wires, since other hangers may be located along the

wires

5 and 6 at suitable distances.

I claim as my invention:-

1. A splicer for trolley wires and the like comprising a bar having a hole in each end, extending angularly from each extremity toward the upper mid portion of the bar, the said upper portion being recessed to expose the inner ends of the holes, means for clamping wire ends in said holes and bending their extremities into parallelism with the longitudinal axis of the bar, and a hanger clamp gripping the said parallel portions of the wires. 35

2. A splicer for trolley wires and the like comprising a bar having a hole in each end, extending angularly from each extremity toward the upper mid portion of the bar, the said upper portion having a groove which is shallow relative to the diameters of the said holes, and which communicates at its ends with said holes, means for clamping wire ends in said holes and groove, and a hanger clamp for gripping those portions of the wire ends which lie within the groove.
