SAMUEL D. STROHM, OF PHILADELPHIA, PENNSYLVANIA.

ELECTRICAL CABLE.

SPECIFICATION forming part of Letters Patent No. 289,165, dated November 27, 1883. Application filed December 3, 1881. Renewed April 19,1883. (N0 model.)

To all whom it may concern.-

Be it known that I, SAMUEL D. STROHM, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Electric Cables; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the' same.

My invention relates to an improvement in electrical conductors, the object being to provide a series of wires with supports, to which the wires may be readily secured and re moved when desired.

IVith these ends in view my invention 0011- sists in certain features of construction and combinations of parts, as will hereinafter be described, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a plan view of one of the wire-supports. Fig. 2 is a view in perspective of a pair of wiresupports, and Figs. 8, i, and 5 are modifications.

A represents a ring or disk, made of metal or any non-conducting material, or both combined. In the periphery of the ring or disk are secured the hooks B. Two of the rings or disks A are located so that their hooks B will be reversed, as illustrated in Fig. 2. The wires 0 are inserted beneath the points of the hooks on one disk, then bent laterally and inserted beneath the points of the hooks B on the next disk, so that the series of hooks on every two adjacent or pair of rings or disks constitute a perfect lock for preventing the accidental displacement of the wires. \Vhen it is desired to detach one of the wires for making a connection or other purpose, the wire is bent in one direction to remove it from the hook of one ring or disk, and then moved in the opposite direction to detach it from the hook of the other ring or disk. \Vhen the rings or disks are located at a little distance from each other, the wires can be easily inserted beneath the reverselyformed hooks,

and then by moving the rings or disks toward each other the hooks are brought into alignment by the wires and the latter prevented from being accidentally displaced. After the wires have been inserted the hooks may be bent so as to form closed staples, if desired.

I11 Fig. 4 I have shown a ringhaving hooks on its inner and outer peripheries, to enable as double series of wires to be supported thereby.

Instead of making the rings or disks inde pendent, they maybe constructed in the form of a spool, as illustrated in Fig. 3, and the periphery of each head or disk be furnished with the hooks, the latter being arranged in reverse order, to enable the wires to be locked therein. These rings or disks may be supported in a tube or pipe inclosing the wires, or they may be employed in the construction of a cable and the wires embedded in insulating material, or themselves insulated and the embedding material dispensed with.

In Fig. 5 I have represented a series of the rings, one encircling another. These rings may be provided with hooks on their outer edges only, or 011 both their outer and inner edges.

I am aware that a square or rectangularshaped trough has had its sides provided with hooks for supporting electric conductors; also, that vitreous insulators made in the form of disks have been provided with radial slots having lateral passages leading to seats for wires, said disks being arranged so that the slots of the adjacent disks will be in reverse order and lock the wires against displacement when turned in one direction, and hence I make no broad claim to such features of construction.

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

In an electric cable, a support for a series of wires, consisting of two insulated rings in close juxtaposition, having their peripheries provided with hooks, the hooks on adjacent rings being arranged in opposite manner, substantially as described.

In testimony whereofIhavesignedthis specification in the presence of two subscribing witi nesses.

SAMUEL D. STROHM.
