CABLE-HANGER Specification of Letters Patent.

Patented Nov. 28. 1911.

Application filed October 1, 1910. Serial No. 584,901.

10 qiurpose of suspending electric cables from supporting wires.

The object of this invention is to provide a. hanger which shall be simple and durable in construction, which may be readily attached or detached, and which Shall clamp the cable securely.

\Vith these and other objects in view which will, be apparent from the following description, I will describe in detail the cable hanger embodying my invention, re :terring for illustration to the accompanying drawings, in which Figure l is a side elevation of my cable hanger in position supporting a cable from a sup iorting or messenger wire. Fig. 2 is a vertical cross section of the same. Fig. 3 is an elevation of the spring wire support or suspending member, and F g. 4 is a vertical cross section of a modified form of my invention.

The insulator or insulating block is composed of upper and lower saddle shaped sections A A 01"." suitable insulating material, having interior longitudinal recesses which embrace the cable C. In the preferred form of my invention the opposing recesses of the sections are dissimilar in contour, one being angular and the other curved to facilitate the gripping action on the cable. The block is preferably polygonal in cross section and may be square or diamond shaped as shown. It is provided with a groove G around the central portion and tapers longitudinally toward the ends.

The sustaining or suspending member comprises a. substantially U shaped spring wire B, having the ends formed into hooks Z), Z), which are adapted to be sprung or snapped over the messenger wire. The lower portion is bent into an outline of the same configuration as the-lwer block to form a seat therefor, and provided with 9pposite inwardly directed shoulders or knees g, g, which bear upon the upper block portion and force the two portions of the block together and securely clamp them about the cable when the two arms are forced together, and the hooked arms are snapped over the-messenger wire Z.

The modification illustrated in Fig. 4, comprises upper and lower saddle-shaped sections A and A, each of which is provided with an interior longitudinal rectangular recess, said sections when assembled embracing or clamping the cable C; as shown, and form a block the cross section of which is rectangular. The arms comprising the supporting or suspension member B are substantially parallel and terminate at their upper ends in enlarged eyes or c1rcu-.

lar hooks 7) which are snapped over the steel or wire strand 13. The opening of each hook is preferably of smaller gage than the diameter thereof. The lower portion of the supporting member B is rectangular to conform to the shape of the block which it oml "aces upon all sides, the knees 7, tending to force the two sections A and A together and thereby secure the cable C. The block is also provided with a. groove G around the central portion and is tapered longitudinally toward its ends as in the case of the block shown in Fig. 1.

it will be seen that the parts may be readily assembled about the cable. The upper and lower members of the insulator are placed in position about the cable and the hanger issprung around the central groove of the insulator. This may be more read ily accomplisl'ied by passing the lower section of the insulating portion into the hanger wire first. Then after passing the cable through the open end of the hanger wire the upper section of the insulator is slipped into place. The resultant construction is a positive strong and compact gripping mechanism obviating danger of looseness or slipping of the cable.

Having thus described 'my invention, I claim as new and desire to secure by Letters Patent,

1. A cable hanger comprising a divided insulating portion having substantially equalupper and lower parts, a resilient suspending member embracing said insulating portion and terminating in hooked ends,

knees'below said hooked ends adapted to engage with the upper part of said insulating portion and hold the parts under pressure when the ends are caused to register.

2. A cable hanger comprising divided upper and lower longitudinally recessed insulnting portions, the lower portion embodying an angular structure, the inner and outer walls of which are substantially parallel, and the recess in said lower portion being V-sheped in cross-section, ahunger for supporting said insulating portions, said hunger having a lower angular portion eonforniing to and embracing the outer walls of said lower portion, and having knees which engage and force the upper portion my hand in presence of two subscribing wit- 15 nesses. i
