TROLLEY-WIRE SUPPORTING AND CONNECTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 674,657, dated May 21, 1901.

- Application filed March 21, 1901- Serial No. 52,183. (No model.)

0 a whmn it may concern:

Be it known that I, GEORGE HENRY RIcKE, a citizen of the United States of America, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Trolley- WVire Supporting and Connecting Devices, of which the following is a specification.

This invention relates to certain improvements in clamps or hangers such as are commonly employed for supporting trolley-wires and the object of the invention is to provide a device of this nature of a simple and inexpensive construction having improved devices for securely clamping-and holding the trolley wire, the devices being capable of ready and convenient adjustment to permit of releasing the wire from the clamp or hanger when desired for purposes of repair or otherwise.

The invention consists in certain novel features of the construction, combination, and arrangement of the several parts of the improved trolley-wire clamp or hanger whereby certain important advantages are attained and the device is made simpler, cheaper, and otherwise better adapted and more convenient for use, all as will be hereinafter fully set forth.

The novel features of the invention will be carefully defined in the claims.

In the accompanying drawings, which serve to illustrate the invention, Figure l is a side elevation showing the improved trolley-wire clamp or hanger constructed according to my invention, and Fig. 2 is an axial section taken vertically through the device in the plane of the trolley-wire. Fig. 3 is a section similar to Fig. 2, but taken through the hanger in a plane at right angles to the length of the trolley-wire. Fig. 4 is a plan view of the wiregripping parts of the improved hanger, and Fig. 5 is a view showing the under side of the upper or gripping member of the hanger.

In the views, 1 indicates a bolt such as is ordinarily employed for suspending trolleywire hangers or clamps from the span-wires, said bolt carrying suitable insulators 2 at its upper end and having its lower end screwthreaded for connection with the gripping parts of the improved clamp or hanger.

3 indicates a U shaped part or member, the lower end of which is bent and flattened out to form an elongated and rounded seat to re ceive the trolley-wire 0c. The upper ends of the arms 4 of the part or member 3 are thickened. and extended up in line with each other at opposite sides of the said seat and are spaced apart suitably to permit the trolley-wire or to slip readily down between them and into the seat, as shown in Figs. 2 and 3.

In connection with the part or member 3 a keeper 6 is employed, said keeper being in annular or ring shape and having a central opening adapted for the passage of the upper extremities of the arms 4 of the part or memher 3, said upper extremities being made reduced, so as to provide on the outer sides of the respective arms 4 shoulders 5, upon which the annular keeper 6 rests and is supported. The keeper 6 prevents spreading of the arms 4 away from each other and is provided at opposite points with inwardly-projected parts or lugs 7, which extend into the space between the arms 4 of member 3, as clearly shown in Fig. 4.

In the space between the arms 4 of the part or member 3 is held a clamping part or member 8, the lower end of which is widened or made laterally expanded and the upper end 9 of which is formed into a narrow shank which extends up between the reduced portions of arms 4 and is held against removal from the space by engagement within the central space or opening of the keeper 6. When the keeper is removed from the arms 4, the clamping member 3 may of course be readily removed from the space between said arms.

The clamping member 8 is adapted to rest at its lower part upon the trolley-wire 00, held in the seat of the U-shaped member 3, and the lower surface of the said part or member 8 is hollowed out or made concaved and is provided with oppositely-arranged series of serrations or tooth-like projections adapted to impinge upon the trolley-wire 00, as shown in Fig. 2.

From the drawings it will be seen that the construction of the upper ends of the arms 4 of the part or member 3 and of the keeper ,6 is such that when the said keeper is in place upon the arms, as seen in Figs. 3 and 4, the engaging parts of the arms and keeper present the appearance of and serve as an integral cylindrical shank for the part or member 3 of the hanger. In the shank thus produced is formed a screw-threaded bore or passage 11, adapted to receive the threaded lower end of the bolt 1, by means of which the improved hanger or clamp is supported. Portions of the screw-threads of the bore or passage 11 are, owing to the peculiar construction of the keeper 6, with its lugs 7 extended between the arms 4, produced upon each of the arms 4 and also upon each of the said lugs 7 of the keeper, so that when the bolt 1 is screwed home the engagement of the screw-threads thereof with the partial threads upon both the arms 4 and lugs 7 will act to securely lock and hold the keeper in place upon the part or member 3, so that these parts are held in proper relation one to the other.

The lower end of the bolt 1 when screwed into the bore or passage 11 is adapted for engagement upon the upper end of the shank 9 of the movable clamping part or member Sin such a Way as to cause the serrated lower surface 10 of said clamping member 8 to be forcibly pressed down upon the trolley-wire m, held in the seat of the member 3, whereby the said trolley wire is securely clamped and held against lengthwise movement between the two members 3 and 8 of the hanger.

From the above description it will be seen that the improved clamp or hanger is of an extremely simple and inexpensive nature and is especially well adapted for use by reason of the facility with which the trolley-wire may be both clamped and released by merely turning the bolt 1 to screw it into or unscrew it from its bore or passage 11, and it will also be obvious that the device permits a very important economy in that it provides a very simple and effective means for clamping the two ends of the wire in case of a break, since the oppositely-arranged serrations 10 of the member 8 are adapted forsecurely clamping the two ends of the wire and holding them without requiring splicing or other expedients.

It will also be obvious from the above descriptionthat the improved hanger or clamp is capable of considerable modification without material departure from the principles and spirit of the invention, and for this reason I do not wish to be understood as limiting myself to the precise form and arrangement of the several parts of the device as herein set forth.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a hanger for trolley-wires and the like, the combination of a part or member having a seat to receive a trolley-wire and provided with arms extended up on opposite sides of said seat,a clamping partor member arranged to bear upon the trolley-wire when held in said seat and insertible e'dgewise between said arms and a part extended between and having threaded engagement with said arms and having its lower end engaged with the clam ping part or member for'actuating said clamping part or member, substantially as set forth.
