TROLLEY-WIRE HANGER.

SPECIFICATION forming part of Letters Patent No. 526,704, dated October 2, 1894. Application filed June 4,1894. Serial No. 513,347. (Nomodcl.)

To all whom it may concern? fBe it known that I, JOHN J. GREEN, a citizen o the county ot' Morris and State of New Jersey, have invented certain new and useful Improvements in Trolley-Tire Hangers, of which the following is a specification, reference being had to the drawings accompanying and forming a part of the same.

The presentimprovements relate to devices for supporting the trolley wire of an electric railway.

The essential feature of the improvements relates to the device by which the said trolley wire supporting mechanism is suspended by hanger or stretcher wires extending laterally across the path of the railway to posts or other supports; and the essential feature of the improvements consists of devices for supporting the said mechanism which are made from sheet metal, struck-up (in distinction to devices made by casting), and composed ofinterlocking or conjointly locking parts.

Iwill iirst describe the said improvements, and in the claims to follow the description I will point out what I regard as new and of my invention.

In the drawings accompanying this specilication Figure 1 is a general elevational view of a section of a trolley wire and of a device for supporting the same, the lateral hanger or stretcher wires that support the trolley wire being shown as apparently in the same plane with the trolley wire, for the purpose of conveniently illustrating the features of this invention. Fig. 2 is a horizontal section of these parts on the line do of Fig. 1; and Fig.

3 shows a similar Section of a modified form of the suspending mechanism. Fig. t shows another modification in side view or elevation, and Fig. 5 is a section of the same on the plane ZJ b of Fig. 4.

Referring to the views in detail A represents the trolley wire. B represents the hanger or stretcher wires which support the trolley wire and which are usually arranged at right angles, or substantially so, to the direction of the trolley wire.

C is the foot or ear-piece which is attached to the trolley wire and carries a screw socket or other means of attachment to the screw the United States, residing at Boonton, inV

shank of the insulating bell D. This bell has a neck extension E, at the top of which is the laterally projecting head F. All of this bell, and its neck and head, may be of insulating material, which parts as shown in the drawings are well known in this art.

The device for supporting the insulating bell consists (see Figi) of a strip or plate of sheet metal G, which is shaped midway of its length to partially surround the neck of the bell and has at each end an eye or socket H or other equivalentdevice adapted to engage with the laterally extending or side stretcher wire or wires B, as shown in said Fig. 1.

J is a strip or plate cut from sheet metal and bent into proper form corresponding to the size and shape of the neck of the insulating bell and which is provided with the ears K, which are passed through holes in the plate G and are bent over and maybe riveted upon the same, particularly as shown in Fig. 1.

In lieu of the combination ot' plate G and the back plate J being made as shown in Fig. 1, these parts may be of two pieces cut from sheetmetal and of substantially the form indicated in Fig. 3, in which these parts are shown as made in substantially duplicate form, but reversely applied Yto the neck of the hanger bell. Here each plate L is provided with a single ear M engaging the extension or hanger part of the other, as do the ears K of Fig. 1.

In Fig. 4 is shown another form of this hanger mechanism where N represents a st rap or plate bent around the middle of the hanger bell neck, its two ends being brought together, see Fig. 5, and forming means of attachment to one of the supporting wires. A forked plate O having the two straps P and surrounding the bell neck above and below the plate N is arranged upon the other side of the said neck and its free ends are brought together, Fig. 5, and constitute the means of attachment to the opposite supporting wire.

I am aware that the supporting mechanism of trolley wires has heretofore been made of castings of various forms and shapes adapted to engage the insulating bell, and adapted to engage or be attached to laterally extending hanger or stretcher wires. In all such cast devices, so far as I am informed, excessive IOC Weight of metal was necessary. In the present construction,the parts of the supporting mechanism are made entirely of sheet metal, which can be bent or otherwise manipulated into form as by being struck up in dies and cut out and formed to the shapes desired. Sheet metal, being capable of bending and of being struck up, permits me in the manufacture of such device to form and shape the same with less Weight of metal than in cases Where such devices are made from cast metal. The practical result of the use ot sheet metal in the manufacturing of such devices, as against devices vfor the same purpose made from cast metal pieces, is chcapness in thel cost and lightness of parts, While yet the desired strength is retained.

That is claimed as new isl. In a trolley Wire supporting mechanism lVitnesses:
