HORACE VAN SANDS, OF NE\V YORK, N. Y.
LOOP INSULATOR.
SPECIFICATION forming part of Letters Patent No. 362,682, dated May 10, 1887.
Application filed January 26, 1887. Serial No. 125,604. (No model.)
To all whom it may concern.-
Be it known that I, HORACE VAN SANDS, of the city, county, and State of New York, have invented a new and useful Loop Insulator, of
which the following is a full, clear, and exact- 'tially, in forming the couplingpiece of the insulator, together with the guard and overlapping shield, entirely of non-conducting material, as hereinafter more fully described, and then definitely claimed.
Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar letters of reference indicate corresponding parts in both the figures.
Figure 1 is a side elevation of my loop insulator. Fig. 2 is a central sectional View of the same.
The inner cylindrical couplingpiece, A, is formed of glass, gutta-percha, or other suitable non-conducting material, and in its ends are secured, preferably in the process of casting, the dovetail shanks of the eyebolts B 13, forming the fastening devices to which the ends of the wires to be connected and insulated from each other are attached, as shown in Fig. 2.
With one end of the coupling-piece A is formed integrally and of a non-conducting material the conical cup shaped shield O, which extends to or slightly beyond the other end of the coupling-piece, and on this latter end is fixed a reverse conical guard, D, also made of a non-conducting material. This guard is much more flaring than the shield G, and when in place projects within the shield nearly to the inner surface of the same.
I prefer to attach the guard D to the coupling-piece A by forming on the coupling-piece a shoulder, A, beveled to correspond with the taper of the guard D, and in the center of the guard an aperture of a size to permit the passage of the eyebolt B therethrongh and fit upon the neck formed by the shoulder A 011 the couplingpiece, the guard then being cemented or otherwise secured thereto. The guard and shield thus combined and arranged prevent rain, snow, &c., from beating in upon the coupling-piece A, and thereby forming an electric connection between the wires. A sufficient space is left between the inner surface of the shield O and the edge of the guard D to prevent water from running from one to the other by capillary attraction. This insulatoris more particularly intended for electriclight wires, as the dry zone constantly maintained thereby on the coupling A will prevent all passage of electricity and danger of forming an arc.
Having thus described myinvention, Iclaim as new and desire to secure by Letters Patent In an electric loop insulator, the combination, with the non-conducting coupling'piece and its end-connecting devices, of a flaring shield extending from one end of the coupling piece and a flaring guard extending from the other end thereof within and closely to the shield, the guard and shield being both formed of nonconducting material, substantially as set forth.
