CHARLES L. GORE, OF NE YORK, N. Y., ASSIGNOE OF ONE-FOURTH TO JOHN D. TOWNSEND, ()F SAME PLACE.

INSULATOR FOR TELEGRAPH-WIRES.

SPECIFICATION forming part of Letters Patent No. 252,857, dated January 24, 1882,

Application filed May 10, 1881.

T 0 all whom it may concern:

Be it known that I, OHAnLEs L. Gonn, of New York, in the county and State of New York, have invented an Improvement in Insula'tors for Telegraphires, of which the following is a specification.

Figure 1 is a plan view of a series of telegraph-wires, showing them insulated and nested according to my invention. Figs. 2, 3, 4, 5, and 6 are face views of various forms of insulators employed by me in carrying out my invention. Fig. 7 is a central section through one of the insulators, showing it applied to a wire. Fig. 8 is a cross-section through a tube containing series of wires insulated according to my invention.

The object of this invention is to substitute for the continuous coverings that are applied to telegraph-wires for the purpose of insulating one from the other a non-continuous insulating means, whereby material will be econoniized, less space occupied, and nevertheless perfect insulation obtained at far less expense than could heretofore be done.

To this end my invention consists in supplyin g the telegraph wire or wires with series of rings ofnon-conducting material, the rings being placed at distances apart to constitute, so to say, brackets, on which each wire is supported at the requisite distance from other wires, and properly insulated.

I desire it to be understood that when I use the term telegraph-wire in this specification it is to include telephone-wires and all other wires used for conducting the electric current for any purpose whatever.

In the accompanying drawings, the letters A A represent telegraph-wires, and B B are rings threaded upon them. Each of these rings is made of glass or other suitable nonconducting material-that is to say, material which is a non-conductor of electricity; and each ring is of such diameter internally that it will be adapted to receive a wire, A, and externally that it will hold any two or more wires at the desired distances apart.

The rings may either be perfectly annular, as in Fig. 2, or of the forms indicated in Figs. 3, 4, 5, and 6, or of other suitable forms.

1 do not limit myself to any specific form of (No model.)

ring, nor to any material for the same, as long as it is a non-conducting material, as specified.

The invention is principally applicable to telegraph-wires or the like that maybe placed in housings or tubings in or on the ground, but may also with advantage be used wherever series of wires are carried through walls in houses, and wherever, in fact, wires are necessarily conducted in bundles or masses from onelocality to another. To properlynest such wires and consume less space than is otherwise required, 1 make the rin gs on the massed insulated wires break joints, as indicated in Fig. 1, so that by this means but one thickness of insulating materialthat is, less than the length of the radius of one disk-will intervene between any two wires, whereas when the wires are completely covered, as heretofore, two thicknesses of insulating material necessarily intervene between any two wires. 1 thus economize in nesting or packing these wires one thickness of insulating material between every two wires that are so nested or massed together. To properly secure each ring B upon its Wire A, small wooden wedges, like that marked a, (shown in Fig. 7,) may be employed, or any other analogous means. The attendant who is to mass the wires or lay them spaces the rings at proper distances apart, the distances being such that the wire cannot sag or bend by its own weight between any two rings. The tube, box, or receptacle 0 containing the telegraph-wires thus insulated and nested may, if desired, have poured or placed into it additional insulating material, of a liquid, semi-liquid, or pulverized form, which material would settle down and till the spaces between the wires and the rings, as indicated in Fig. 8.

I claim 1. The telegraph-wire A, having series of insulating-rings B B strung directly upon it, the said rings being separated from and not in contact with each other on the wire, and made of non-conducting material, substantially as here- 5 in shown and described.

2. The nested or massed telegraph-wires A A, each havinginsulating-rings B B strung upon it, said rings being arranged on the several wires so as to break joints, thereby allow- ICC) lating substance which fills the remaining spaces between the Wires when placed in a pipe or box, whereby the wires are insulated and protected from moisture, substantially as herein shown and described.

This specification of my invention signed by methis 9th day of May, 1881.

CHARLES L. GORE.
