HANGER.

Application filed April 6, '1925. Serial No. 21,192.

This invention relates to new and useful improvements in a hanger.

One object of the invention is to provide a hanger, of the character described specially designed for supporting a conductor, and more particularly designed'for supportmg a trolley wire from the messenger wire.

Another object of the invention is to provide a hanger which is flexible, or yieldable so as to permit the trolley wire to be elevated, relative to the messenger wire, without in ury to the latter, or to the hanger. A further feature of the invention rcsides in the provision of a hanger so constructed and attached to supporting messenger wire and the trolley wire, that the adjacent hangers will hold the parted ends of either wire, in case of breakage, of either wire, so that said parted ends may be readily reunited. 3

, In the equipment of electric railways the messenger wire, or supporting wire for the trolley wire, is strung from pole to pole over the track and sags between the supporting poles and the trolley wire is suspended from it byhangersa It is desirable that the trolley wire be heldagainst sagging, so that it .rlll be comparatively straightand thehangers midway between the poles are shorter than those nearer the poles, the relative length of the, hangers being such that the trolley wire will be held, horizontal and in position not to sag. V

As the trolley wheel passes along underneath the trolley wire this wire will be some- 7 due to the electric current passing from the trolley wire along the hanger to the Ines-' It is the chief object of this invention to provide a flexible, or yieldable type of hanger which will support the trolley wire, and permit the said movement thereof without injury to the supporting, or messenger wire.

With the above and other objects in view senger wire.

this invention has particular relation to certain novel features of construction, operation and arrangement of parts an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 shows an edge view of the hanger showing the wires in section.

Figure 2 shows a side view thereof, and Figure 3 shows a vertical sectional view of the trolley wire clamp.

Referring now more particularly to the drawings, wherein like numerals of refer ence designate similar parts in each of the figures, the numeral 1 designates a supporting wire commonly known as the messenger wire, and the numeral 2 designates the trolley'wire.

The messenger wire 1 is supported on poles, set a distance apart along the railway tra'cln'in theusual way. It is clear that this messenger wire will sag, somewhat, between, the poles. This wire is provided to support the trolley wire 2 i from by the hangers. The trolley wire should be held against sagging so far as, possible, and for that reason the hangers nearthe supporting poles, will be somewhat longer than those further away from said poles, the hangers varying in length, as required, to maintain the trolley wire as nearly straight as possible, but being otherwise similar. I p

I Each hanger includes two wire clamps connected by links, or other flexible, or yieldable connection. As shown, and as a preferred construction, the messenger wire clamp 8 consists of an open ring 4: which surrounds the messenger wire 1 and which is formed with a depending eye 6, and opposite the eye the clamp has the outwardly turned, coinciding ends 7 7 adapted to receive the clamp bolt 8, which passes through said ends and is held in place by the nut 8. The ring 4 will usually be clamped tightly on the messenger wire but in some cases it may be found necessary to give it a loose fit thereon to permit adjustment. i The trolley wire clamp, 9, may be of any form desired. A preferred form consists of two jaws 10, 10. These jaws are clamped together by a clamp bolt 11, which passes through them and is held in place by a clamp nut 12. The lower ends of these jaws have inside transverse beads, or teeth, 13, 13 which fit into corresponding grooves 14:, let,

which is suspended thereopposite sidea oi" the trolley wire. The underside of the trolley wire in clear, the clamps 9 living above said wire so an not to he etrni'k hy the trolley wheel.

The margins of the clamp jaw 10' have (he side teeth 15, adapted to project into opposing notches; 1G, 16, in the jaw 10 to hold said jaws in alignment.

There is an eye 17, formed with a shank 18 which fits between the jaws of the clamp 9, said clamp bolt 1.1 passing thron h aaid ahank to Secure said clamp. lhe e 17 receive the end linlei; 11%}, i9 reaper lively. which in turn, are connected hy one or more iiiterniediale links 20, the ninnhers oi connecting links-z depending on the length of the hanger desired.

As the trolley wheel passer: along the trolley wire underneath the hangers it will slightly ele'ate said trolley wire and the flexible connection between the wire clamps 3 and 9 will permit this without injury to the messenger wire.

In case either oi. the wires. partas sometimes occurs, the hangers will hold the parted ends and prevent them from moving far apart, or falling down, no that they may he qiiickly and easily reunited.

hat I claim is 1. A hanger iior snepending a trolley wire from a messenger wire and including a messenger wire clamp consisting of an open ring having :1 depending: eye and whose upper ends coincide and are provided with a. bolt hole to receive a securing belt, a trolley wire clamp consisting of oppositely disposed jaws. a clamp bolt and nut connect- 5115.; said jaws the lower ends; oi the jaws having teeth adapted to [it into the corresponding; grooves on opposite nidea ol the trolley wire. one of said jawe haying ineide notches and the other haying projecting: teeth which fit into said notches to secure said jaws in alignment and linle; llexihly connecting said clamps together.

2. A hanger for suspending a. trolley wire from a messenger wire said hanger including a messenger wire clamp and a trolley wire clamp said trolley wire clamp coinprisingi; two jaws: and a clamp hell; for connecting the jaws higother, the lower ends of said jaws having inside teeth adapted to [it into corresponding recesses on opposite sides; of the trolley wire, the margins of one oi? said jaws having notches" and the other jaw having projections which fit into said notches to maintain said jaws in alignment, an eye formed with a shank fitted between said jaws and through which said holt pawsce and a flexible connecting member connected at one end to naid eye and at its other-vial to said niesaenger Wire clamp.

53.
