To all who-m it-moy concern: iRPfQl'LllC-l} may now be had to l ig. 3 in V Be it known that I. Trinononr; Vansnr, a which a cross or. or rod 14, that corresponds citizen of the United States and a resident to the rod 4: of Figs. 1 and i2, is similarly of Pittsburg, in the county of Allegheny suspended from a cross cable 15 bv means of I I new and useful Improvement in Overhead hangers l2 and 13 of the other figures. Ina q Line Structures, of which the following is a ;\st( zid ot the cables 8 and 9, cables 18 and 19 a agr m. r Pennsylvania, have invented a hangers 1G and 17 which correspond to the 60 specification.

My invention relates to overhead electric line structures and has special reference to such line structures as are adapted for relatively high-voltage railway service.

The object. of my inventionis to provide improved means for etl'ectively supporting to Fig. 1, of a cross span structure provided with a steadying device for preventing:

lateral displacement of the conductor.

. thereon. The cross bar 4 may be in the form of a T-iron' bar or a rod or bar of aoy other convenient; section and 1s suspended from poles 6 and 7 or other stationary supports,

ocated at the respective sides of the trolley conductor, by means of cables 8 and t) that connect therespc-ctrve ends of the rod or 1 cross bar 4 to eye bolts 10 with \vhich'the 2 Another cable 11 poles are provided.
