SUPPORT FOR ELECTRIC-RAILWAY WIRES.

SPECIFICATION formingpart of Letters Patent No. 398,489, dated February 26, 1889.

Application filed September 19, 1888. Serial No. 285,768. (No modeld To a?! 1/71 0/)? '1'/' 11/41 can earn Be it known that I, THOMAS ll. BRADY, a

Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Poles and Brackets for Supporting \Vires for Electric Railways, of which the following isa specification.

My invention relates to improvements in suspending the wires for electric railways; and the objects of my improvement are to the wire-holder adjustable upon the bracketarm, and to improve the general construction for the sake of economy in production and convenience in setting up the parts.

In the accompanying drawings, Figure l is a side elevation, partly in horizontal section, of my pole and bracket-arm. Fig. 2 shows, respectively, a plan view and side view of the cap-iron. Fig. 3 shows a side view and front view of the truss-iron that is secured to said cap-iron, and Fig. 4 shows inside elevation a slight modification in the end of the bracketarm.

A designates a pole to be set up on one side of the roadway, and B the cap-iron which is secured to the upper end thereof. The body of this cap-iron is tubular, to be fitted to the upper end of the pole, and it is provided with a lateral lug, 5, containing two holes or mortiscs, 6, Fig. 2, and an upwardly-projecting lug, 7, having a semicirci'ilar recess in its upper edge.

I form the bracket-arm C in the form 01' a truss, as shown. This truss composed of a the lower bar or tube, 8, truss-irons 9 1.0 11. 12

13, truss-wire 1i, and extension 15. The truss-iron has two hooks, 1 (5, upon its under side, which are hooked into the i'nortises (i of the cap-iron, while the body of the rod 8 en- I hold the bracket-arm tirmly in position. The

it an ordinary wireho1der, 18, from which the The extension 15 slides within the tube 8 in the construction shown in Fig. 1, and is fastened in place by the setscrew 1i), whereby it may be extended outward or inward to brin the wire-holder and wire in their proper position over the track. After the extension is thus adjusted the extension-wire may be attached, as shown, so lessen the number of poles employed, to make 1 tcrs the recess in the upwardly-projecting lug 7 of the cap-iron. The end truss-iron, 9, has

of said brace is fastened to the pole, so as to as to form a continuation of the truss-wire 14 to substantially the end of the bracket-arm.

In Fig. substantially the same construction is shown, except that the extension 15 is adjusted within sockets 21 and 22, instead of within the rod By my improvement it is only necessary to place the poles upon one side of the track; the wire-holder may be adjusted to bring it centrally with the track, and the parts are cheaply produced, easily put together, and are of substantial construction.

I claim as my invention 1. The herein-described support for the wires of electric railways, consisting of the pole A, the bracket-arm C, and the adjustable extension 15 at the outer end of said bracketarm, substantially as described, and for the purpose specified.

2. The bracket-arin C, consisting of a lower bar, truss-irons, truss-wire, and an extension at the outer end, and the extension-wire 20, for forming a continuation of the truss-wire to near the outer end of said bracket-arm, substantially as described, and for the purpose specified.

3. The eombinat ion of the pole A, cap-iron 13, having lugs 5 and 7, the truss titted to said cap-iron, and the brace 17, substantially as described, and for the purpose specified.
