HANGER non TnoLLnY-wmEs.

Application filed March 21, 1912. Serial No. 685,232.

To all whom it may concern:

Beit known that we, WILLIAM C; STARKEY and G ENN H. Bonus, citizens of the United States, and residents of Mansfield, in the State of Ohio, have invented certain new and useful Improve ments in Hangers for Trolley-Wires, of which the following is a specification.-

Our invention "relates to suspension "devices for electric conductors, and has more particular reference to improvements in trolley wire'hangers, of the typegenerally known as catena'ry hangers. I I

The 0l316Ct, primarily of our invention, Is

to provide a cheap, efficient "and durable\ hanger for catenary systems of suspending" trolley wires, Which will be exceedingl 7 strong, but light in'weight. I

A further object is to provide an improved catenary hanger which can be made of two parts, namely, a wire holding member and a suspensionmember, assembled in operative relation in a simple and efiicient Vmanner. l A further Ob ect isto'provide an improved trolley wire hanger which can be quickly and securely attachedfto the wire to besuspended, and which, when attached to the wire, will offer no obstruction whateverto the traveling'trolleyor contact member.

To the attainmentofthese ends, and the accomplishment of other'objects hereinafter appearing, our invention consists in the fea- 1 tures'of novelty disclosed in the construction, j

combination and arrangement of parts shown in the accompanying drawings, which illustrate one embodiment of our invention, andin wh1ch- Figure 1 is a view in elevation of our-im-- proved hanger attached to a trolley wire.

Fig. Qis an end'viewof the lower portion threofl-the Wire holding member'being shown in transverse section Fig. 3 is a transverse s'ectional'view'on line 8-3 of Fig. 1;'-'

Fig; tis a side elevation 'ofthe wireholding member, the suspension member being" omitted; Fig. 5 is asimilar view OfaTnOdk fied form of wire holdingfmember; Fig. ;6 is a view similar to'Figi 1 showing a mod1-o tied structureembodying our invention; Fig;

7 is ,an end view thereof; 'and'Fig. 8 is a longitudinal, sectional viewthereof on Inthedrawings we have shown our invn-j 131011 as embodied in a hanger-which is adapted for supporting trolley'wires of these called grooved and figu're 8 types, but it i s to be understoodthat our improved hanger is'equally as'well adaptedto the'round or other types of wire.

The hangers or wire suspending devices, shown in the drawings each embody a wire holdingmember A, and asuspensionmein' ber Bis disposed preferably at substantially right angles thereto, and each member thereof is composed preferably of a single piece of metal; The member or ear A has a lower portion" 1 which agroove 2 is'formed for the'purpose of receiving the trolley wire-"3'.

Theshapeof this groove variesin accord ancewith the cross-sectional shape of the Wire to be'hung. In fact, the groove or channel may be given any desired shape,

butWe prefer that it conform to that ofthey wire so that a more accurate connection may be made and then soldered therein if desired. The edges or lips tarepreferab'ly made'bendable so that they can be hammered or pressed inwardly to embrace the wire,

when used with the grooved or figure 8 wire; the bendableQlips are madeof such thick-- ness that when they are'forced or bent into the groovesz5 of the wires as shown in- Fig. 8,1tlieylie within the general confines ofthe wireand donot noticeably-increase the size of the wire at these points; For the sake of lightness in weight, without sacrifice to strength, we make the portion 1 of substantially uniform thickness, and provide thereon one or two integral members'or flanges 6 dependingon'the particular requirements to which the hanger is tobe adapted. These upstanding members 6 constitute means to 1 which the suspension memberB may be attached, and if desired they may be formed as a singleshort lug or lugs as the case may be: If the wireholding member A is made of'the so-called extruded brass which is, as

well known, "formed'by forcing brass in aheated} viscous state under high pressure through'a die (and'itis preferablyso made),

the flanges ,ormembers 6 extend the length off theylo'wer or wireholding portion These members .or flanges" 6 also serve asstrengthening ribs against bending strains: 9 In Figs-.-1, 4t and 6 'weha've-shownthe flanges as tapered toward the outer ends for the sake 1 for attachment to the messenger wire. This permits the straps 8 to be cut from long lengths of stock strapmetal and a great saving in manufacturing expenses is accomplished. Figs. 1, 6, 7 and 8 show a method of forming the upper endsof the strap 8 for attachment to a messenger wire.

Asshown the upperportion thereof may be' doubled back upon itself to form a long loop 15, andthe end 14 may be turned laterally to close the lowerv end ofthe loop and prevent thehanger from becoming acci dentally unhooked fromthe messenger.

As before intimated, the number of flanges 6 depends to some extent upon the -manner in which the suspension member" B is to be attachedtothe wire-holding mem her A. For instance, one flange or rib 6,

may be formed on the member and the lower end of the suspension strap may-bedoubled back on itself or bent to form an eye, loop or hook 9. This may be hooked into a slot or spring 10 in the flange or rib 6 (Figs. 1, 2, 4 and 5) and the .end portion 11 and the adjacent metal 12 may be jammed together oroffset to close the hook and position the suspension strap insubstantially central alinement with the member A. It is seen, however, by referenceto F igs. 6, 7 and 8, that if desiredthe member A may be pro- 1 'vided with two parallel flanges 6 spaced apart to form a slot or channel into which the squared lower end 16 of the suspension" strap maybe placed, and a rivet or bolt 17 passed through suitable holes in theflanges and strap to bind the parts together. 7

It is thus seen that our improved hanger possesses the combined advantages of sim} plicity, durability, cheapness in manufacture and neatness in appearance.
