Specification of Letters Patent.

Patented Nov. 1, 1910.

Application filed December 7, 1909. Serial No. 531,776.

full, clear, and exact description.

This invention relates to a hanger for suspending electrical cable wires from a suitable supporting cable.

An object of this invention is to provide a device which will be simple in construction, strong, durable, inexpensive to manufacture, and easily adjusted.

A further object of this invention is to provide a cable hanger with a stirrup having a locking member pivotally connected thereto, said locking member being made of a single strip of wire bent and twisted on itself.

These and further objects, together with 1 the construction and "combination of parts, will be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this specication, in which similar characters of reference indicate corresponding parts in all the views, and in which- Figure 1 is a perspective view showing one of my devices attached to the supporting and current cables; Fig. 2 is a vertical transverse section; Fig. 3 is a fragmentary top plan view; and Fig. 4 is a vertical longitudinal view, partly in section.

Referring more particularly to the separate parts, 1 indicates a suitable supporting cable, which is adapted to be strung from suitable supporting posts in a continuous manner. The cable 2, to be supported, consists preferably of a hollow lead tubing, in which a plurality of electrical conducting wires are threaded and properly insulated. The cable 2 is suspended from the supporting cable 1 by means of a cable hanger 3. This cable hanger consists of a strap or stirrupv 4, which is preferably U-shaped in -form and provided with perforations at the upper end of each leg thereof. Rotatably supported in the openings in the legs of the stirrup 4, there is provided a pivot pin 5, whichhas its ends 6 and 7 upwardly turned so as to retain the pin and the stirrup together.

Pivotally supported on the pin 5, there is provided a locking member 8, which is for the purpose of securing the cable 2 to the cable 1 1n a predetermined position. This locking member 8 is preferably formed of a' sin le piece of wire bent intermediate its en s to form an arcuate corrugation 9, which is adapted to encircle the supporting cable 1. From each side of the corrugation 9, the wire is bent back on itself to form legs 10, continuations of which are coiled one or more times around the pin 5, to form a hinge joint with said pin 5. Thence the lengths of wire converge toward each other to a point 1l, where they are twisted around each other a number of times to form a rigid stiifening shank 12. The strands of wire then separate and extend at right angles to the shank 12 at 13, and then at right-angles to themselves to form flanges 14, which are adapted to grip the supporting cable 1 on opposite sides.

The method of using the device will be readily understood when taken in connection with the above description. In attaching f the hanger to the cable, the stirrup or strap 4, which is detached from the locking member 3, is slipped on the under side of the cable 2, and the cable 2 forced up toward the cable 1. The locking member is then placed above the supporting cable 1 with the long shank 12 in a vertical position, and the ends of the pin 5 slipped into the perforations in the hanger 3. The shank arm 12 is then swung downwardly, raising the cable 2 toward the cable 1, and then lowering it slightly as the short arm of the locking member formed by the legs 10 and the corrugation 9 slips beyond the center line of support, extending through the pin 5. The flanges 14 may be then forced to tightly engage the supporting cable 1 on each side thereof. The cable hanger will thus be positively locked in position, supporting the transmission cables with the greatest amount of stability.

It is to be noted that when the locking member' 8 is in its locking position, as illustrated in Fig. 4, the short arm thereof engages the supporting cable l slightly to the left of a line drawn through the center of the pin 5, thus causing the weight to tend to force the short arm toward the left. This, however, forces the long arm more intimately into contact with the upper side of the supporting cable 1, thereby positively preventing the cable hanger from being accidentally disengaged. When it is desired to detach the cable Hanger 8, the 4,cable 2` is forced u) toward the cable l, and the short arm sipped to the other side of the pivot pin 5, and the long arm or shank l2 raised, in which position the stirrup et may be detached from the pin Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a 1cable hanger, the combination With a stirru-p, of a pin connected to said stirrup, and a locking member pivotally connected to said pin and ,having a short arm adapted to be thrown beyond the center line of support extending through said pin.

2. In 'a cable hanger, the combination with a stirrnp, of a pin connected to said stirrnp, and la locking member pivotally connected to `said pin and comprising a pair of arms so disposed as to extend on opposite sides of said pin when in their locked position.

3. lIn a cable hanger, the combination with a stirrnp adapted to support a cable, of a locking member adapted to engage a supporting cable, and inea-ns for pivotally connecting said locking member with said st-irrup, said locking member comprising a single length of Wire bent on itself to form enga-ging portions which are adapted to abut against said supporting cable.

4. In a cable hanger, the combination With a stirrup adapted to engage a cable, of

a pin connected to said stirrup, and a locking member pivotally connected to said pin and adapted to engage a supporting cable, said locking member comprising a single length of wire bent intermediate its ends to form a corrugation which is adapted to engage said supporting Wire, and having legs extending from each side of said corrugation and coiling one or more times around said pin, the lengths of said Wire extending from said pin in a converging manner toward each other, from whence they are twisted one around the other to form a stiii'ened shank, the ends of said lengths extending in spaced relation to form a U- shaped grip which is adapted to embrace said supporting cable.

5. A cable hanger, comprising a supporting member and a suspending member pivotally connected together, said members having juxtaposed concave faces arranged in opposition to each other, and means on one of said members adapt-ed to lockingly engage a cable, Where y said members are locked against relative movement.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
