C. B. ELLIOTT. TROLLEY WIRE HANGER.

(No Model.)

No. 499,662. Patented June 13, 1893.

UNITED STATES PATENT OFFICE.

CHARLES B. ELLIOTT, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO THE REVERE RUBBER COMPANY, OF SAME PLACE.

TROLLEY-WIRE HANGER.

SPECIFICATION forming part of Letters Patent No. 499,662, dated June 13, 1893. Application filed August 8,1892. Serial No. 142,431. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES B. ELLIOTT, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Hangers for Electric- Railway WVires, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention is in the nature of an improvement upon that set forth in my Letters Patent No. 476,192, dated May Sl, 1892, for hangers for electric railway wires. In my former invention the upper member of the hanger was a metallic shell having rigidlyprojecting lateral wings or hooks integral with its sides and bottom. By my present improvement thesewings or hooks are independent of the shell and form parts of aringfittingloosely into a peripheral groove in the wall of such shell so as to swivel therein. The ring is cast in two parts united by bolts passed through ears or flanges thereon. In my formerpatent, the insulating material, within which the head of the lower hanger was embedded, was represented as wholly within the shell and its depending tubular extension, and covered by a metallic cap. I now omit the metal cap and cause the insulating material to project over the upper edges of the shell and serve as a cap; and I form a sleeve of such material inclosing and concealing said tubular extension, and affording much more complete insulation than was secured by my former plan.

In the drawings, Figure 1 is a vertical central section through my improved hanger, showing the position of the several parts. Fig. 2 represents, in perspective, the swivelring detached, and Fig. 8 is a similar view of the rubber-filled shell.

A is the outer shell or body of the hanger, having in its periphery a broad groove B.

C is the ring fitting loosely into said groove, so that the shell may swivel therein, and D D are wings or hooks formed in one with said ring, set vertically and edgewise with relation thereto, and adapted to engage with the suspending wire which, in street railways, is stretched across the street from pole to pole. Such wire passes from hook to hook across the top of the shell A, instead of around its side as illustrated in my former patent. The

ring is cast in two parts, each having one of the hooks D integral with it, and both formed with terminal flanges E extending outwardly to receive a bolt and nut F,or equivalent fastening, so that when these parts are brought together, around the shell, and united in a ring, a swiveling connection therewith is secured.

G representsthe bottom of the shell A, and II a depending, tubular extension thereof.

J is the flat head and K the depending, threaded stem of the lower member of the hanger, such head and stem (except its threaded extremity), being embedded in a mass of semi-rigid insulating material L,preferably a low grade of vulcanized rubber or its compound. This material fills the shell and its tubular extension H, and surrounds and incloses such extension, as shown in Fig. 1, while its upper surface is crowning and extends marginally above the upper edges of the shell to constitute a cap therefor. The insulating material is interposed between the two parts of the hanger, and extends like a sleeve around the depending tubular part II of the shell, completely insulating it.

I claim as my invention- 1. The describedsuspendingand insulating devices, consisting of the shellAformed with a peripheral groove B, and the swiveling ring C therein, made in two parts suitably joined and provided with hooks D D, in combination with the insulating material L within such shell and with the hanger J K having its broad head embedded in said material and its depending stem protruding therefrom through the bottom of the shell, substantially as set forth.

2. In an insulating hanger the shell A G with its reduced tubular extension II, and the member J K inclosed therein with its threaded stem protruding, in combination with the insulating material L filling said shell, interposed between it and the hanger J K, and surrounding said tubular extension, substantially as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 6th day of June, A. D. 1892.

CHARLES B. ELLIOTT.
