TROLLEY-WIRE SPLICER.

Application filed January 7, 1922.

To all whom it may concern:

Be it known that I, WILLIAM SoHAAKn, a

citizen of the United States, and a resident pf Httsburgh, in the county of Allegheny an d State of Pennsylvania, have invented a new and useful Improvement in Trolley- .Vire Splicers, of which the following is a specification.

My invention relates to splicers for trolley conductors and it has, for its object, to provide a device of this character that shall be of greater strength and more effective and durable in service than similar devices heretofore employed.

Another object of my invention is to provide a trolley splicer that shall have a lower resistance than those heretofore constructed, without lessening its strength.

leretofore, trolley splicers have been made of cast bronze, which has from six to eight times the specific resistance of copper. There has been some deterioration caused in bronze and brass trolley splicers, when used in connection with a trolley wire, because of Z the heavy current carried thereby.

F or a better understanding of my invention, reference may be made to the accom panying drawings,

Figure 1 of which is a view, in side elevation, of a trolley splicer constructed in accordance with my invention; and

Fig. 2 is a cross-sectional view, taken along the line H ll of Fig. 1.

Referring to Figs. 1 and 2 of the drawing, a trolley splicer 1, possessing the general outline and structural characteristics of a trolley splicer that i well-known in the art, is provided with a plurality of longitudinal channel portions 2, in which the ends of a plurality of trolley conductors 3 are positioned by means of chucks 1, in accordance with the method illustrated in Patent No. 1,206,259, granted to me on Nov. 28, 1916, and assigned to the Westinghouse Electric & Manufacturing Co.

A rod 5, made of some metal possessing relatively great strength, such, for example, as malleable iron, is cast within the central part 6 of the splicer 1 and constitutes a part thereof. The rod 5 is covered with a heavy coating or sheathing of copper 7 for lessening the resistance of the splicer. The ends 8 Serial No. 527,559.

of the rod 5 are flattened to increase the strength of the splicer 1 by preventing the rod from becoming separated from the metal of the central portion 6 of the splicer.

From the description of this splicer, it is apparent that the strength of the splicer 1 has been increased by employing a rod or bar of relatively great strength for the central portion of the splicer, and the electrical resistance of the splicer has been lessened by 111%}.118 of the copper coating surrounding the re While I have illustrated my trolley-splicer in its preferred form, it is apparent that minor modifications may be made in the shape and arrangement of the parts of the splicer without departing from the spirit of my invention. I desire, therefore, to be limited only by the scope of the appended claims.

I claim as my invention 1. A trolley-concluctor-supporting device comprising a plurality of integrally cast clamping portions having a reinforcing member of different material cast therewith.

2. A trolley-conductor-supporting device comprising a plurality of integrally-cast clamping portions having a reinforcing member of different material cast therewith, said member being covered with a coating of relatively low-resistance material.

3. A trolley-conductor-supporting device comprising a plurality of end clamping portions and a reinforcing member therebetween of different material from said clamping portions.

4. A trolley-splicer comprising a plurality of end-clamping members and an enclosed reinforcing member therebetween.

5. A trolley-splicer comprising a plurality of end-clamping members, and a reinforcing and a conducting member permanently located therebetween.

6. A trolley-splicer comprising a plurality of integral clamping portions and an additional metallic member permanently located therebetween.

7. A trolley-splicer comprising a. pluraL ity of end-clamping members, a reinforcing member ,therebetween and a conducting material surrounding said reinforcing member.

8. A composite trolley-splicer comprising a plurality of bronze end-clamping members and a malleable-iron reinforcing member therebetween. f r

9. A composite trolley-splicer comprising 5 a plurality of bronze end-clamping members and '& malleable-iron reinforcing" member therebetween and cast therewith.

1.0. A. composite trolley splicer compriscember, 1921.

ing a, plurality of bronze end-clamping members, a malleable-iron reinforcing member and a copper covering for said reinforcing member.

In testimony whereof; I have hereunto subscribed my name this 23rd day of De- WILLI M- SGHAAKE.
