TROLLEY-WIRE SUPPORT.

Specification of Letters Patent.

ratented April 24, 1906.

Application filed May 4, 1905. Serial No. 258,775.

To (11/ [rim/11. it may concern:

Be it known that we, JAMES HENRY LANE and Unniii GULNIOK, citizens of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Trolley- W'ire Supports, of which the following is a specification.

Our present invention relates to an impro vement in trolley-wire hangers or supports designed particularly for use with our im proved trolley-wheel guard which forms the subject matter of a separate application filed on even date as this application; and the object of our hanger or support is to provide a simple, cheap, and durable device for holding and supporting a trolley-wire to the arms of the pole and also at junctions where one line crosses another or at switches where a branch line runs into or from the main line, the same principle being followed in the construction of all the hangers or supports, as will be fully set forth later on.

\Vith these briefly-stated objects in view the invention comprises certain details of con struction and novelties of combination and arrangement of parts, as will be fully set forth in the following specification, and pointed out in the claims, reference being had to the drawings, in which Figure 1 is a perspective view of the hanger used for supporting the line-wire along a straight track. Fig. 2 is an end view of the same. Fig. 3 is a cross-sectional view. Fig. Al is a diagrammatic plan view on a reduced scale. Fig. 5 is a plan view of our hanger used at crossings. Fig. 6 is an inverted view of the same. Fig. 7 is a detail section drawn on the line 7 7 of Fig. 5. Fig. 8 is a side elevation of the construction shown in Figs. 5 and 6. Fig. 9 is a detail view of the hanger we employ at switches or where one line branches in or from the other, and Fig. 10 is a detail view showing the upper portion of the giiard arms and their engagement with our hanger.

Referring to Figs. 1 to a, inclusive, it will be seen our hanger or support A is composed of an upper member B, having a central socket B, in which fits a bolt or other connection by which a hanger as awhole is connected to its support. The base of the member B tapers upon its side from the center to each end, as shown most clearly in Fig. 4, and extending from the base upon each side is a flange C (l, which extends throughout the entire length of the hanger.

Depending from the central portion of the under side of the flanges and extending throughout the longitudinal length of the hanger are arms D D, between which the linewire E is held, the arms being concaved upon their inner surfaces to lit the wire, and their ends are su'fliciently reduced to permit them being bent around the wire after it has been placed in position, and thereby securely clamping it to the hanger. These arms may branch from a single depending portion if found necessary; but the construction shown and described is preferable, as it greatly adds to the strength and durability of the support.

The under surface of the flanges, between the depending arms and edges of the flanges, form contacting surfaces or treads, against which the flanges of the wheel engage as it passes the support.

In Figs. 5 to 8, inclusive, of the drawings, we show the construction employed at the intersection of two lines, and while we have shown the support used where one line crosses at an oblique angle to the other it will of course be understood that they may be made to cross at any angle whatsoever. In the construction shown in Figs. 5 to 8 it will be seen the same principle of construction of our hanger is carried out, only we unite the upper members B at one end, as shown, at B the center being provided with an apertrue B, by which the hanger is suspended from its support. The only change or difference, is that we cut the flanges G as shown at C and the members B as shown at B, the cutout portion 0 being for the purpose of permitting the upper ends of the guard-arms carried by the trolley-pole, and the cut-out portions B also permit the passage of the inwardly-projecting members of the guards.

When the flanges are cut out, it will be seen they leave a bearing-plate F in the central portion of the hanger, which provides a beariug-surface for the wheel; but the distance between the inner ends of the flanges is not sufliciently large to permit the wheel being drawn from its direct course. Of course where one line crosses another it is necessary to break the circuit, and it will be seen that the depending arms B are also cut, and by inserting or lining the space between the arms with insulating material the current will be broken, and in this case of course the line-Wires will be connected with short insulated wires to complete the circuit; but Where it rnakes no difference if the current should run from one line to the other or where it is desirable that it should-run from one line to the other the insulating material is omit ted, and the arms of the hanger then form the conductors for the current.

Where the line is provided with a switch or branch, a special form of hanger might be used, such as is shown in Fig. 9 of the drawings; but in this construction the same principle is also sought, and a detailed description is thought unnecessary.

From the foregoing it will be seen that We employ a simple and durable construction of hanger that may be used with equal effectiveness upon lines other than those upon which our special form of trolley-guards are used, as the trolley-wheel will readily slip past a hanger without becoming disengaged from the line-wire. The advantages, however, in the flanges are twofold, first, that they form a tread for the wheel, and, secondly, they form projections over which the in- Wardly-projecting ends of the guard-fingers may extend, and in order that the finger may readily slip past the hanger we bevel the upper member, as shown most clearly in Fig. 4 of the drawings; but this feature is not absolutely essential, as the upper member may be reduced in thickness throughout its entire length; but by making it agreater width and gradually tapering it toward its end greater strength and durability are maintained.

Having thus fully described our invention,

What we claim as new, and desire to secure by Letters Patent, is

1. A trolley-wire hanger comprising an upper member, flanges projecting horizontally therefrom, said flanges being of an even plane throughout their entire surface, and arms depending from the central portion of the hanger.

2. A trolley-wire hanger comprising an up per member having horizontally-extending flanges projecting from the base thereof, said flanges being of an even plane throughout their entire surfaces, and arms depending from the central portion of the hanger for the purpose specified.

3. A trolley-wire hanger comprising an upper member, the sides of which taper from the center toward each end, horizontallyprojecting flanges extending from the base of the upper member and throughout the entire length thereof, and arms depending from the central portion of the hanger.

4. A trolley-wire hanger comprising an upper member having laterally extending flanges projecting from either side, and from the base thereof, and throughout the entire surface, and arms depending from the central portion of the hanger.

5. A trolley-wire hanger comprising an upper member, laterally-extending flanges projecting horizontally from the base of the upper member and from each side thereof, said flanges being of an even plane throughout their entire surface, and arms depending from the central portion of the hanger.
