Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed December 23, 1904. Serial No. 238,173.

To all whom, it may concern:

Be it known that I, JASPER N. BELL, a citizen of the United States, residing at Stratford, in the county of Hamilton and State of Iowa, have invented a new and useful Adjustable Support for Telegraph Lineires, of which the following is a specification.

My object is to prevent the annoyances and interruptions of business incident to contact of wires and to save the time, labor, and expense required in disconnecting telegraph and telephone line-wires that become connected and entangled by swinging and contacting between lineposts.

My invention consists in providing and applying supports adapted to be connected to parallel line-wires midway between line-posts as required to hold the wires apart, as here inafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of one-half of an insulator adapted to inclose a line-wire. Fig. 2 shows two of the insulators connected in right-angled positions relative to each other by means of a single piece of wire coiled around them to bind the two mating parts of each insulator together and to retain the two insulators connected. Fig. 3 is an end view of an insulator composed of two mating parts fitted together. Fig. 4 is a perspective view that illustrates the positions of a wire-holder and an insulator relative to a wire as they must be placed before they can be combined as required for practical use on a line-wire. Fig. 5 is an end view of an insulator that shows grooves in the inside face of one of the parts and projections on the inside face of the mating part fitted into the grooves as required to prevent them from slipping laterally relative to each other. Fig. 6 is a perspective view that shows line-wires supported by crosspieces on posts in a common way and the linewires connected and held apart by the insulators and wires coiled on the insulators as required in practical use. Fig. 7 shows how parallel line-wires in'horizontal planes are connected and also how two or more of such parallel line-wires at different points of elevation are connected by means of the insulators and wires coiled on the insulators. Fig. 8 is a modification of Fig. 7 and shows linewires in a horizontal line and line-wires in a vertical line connected by means of straight bars. Fig. 9 shows how the insulators are connected with the straight bars by means of the wires coiled on the insulators.

The numeral 10 designates the half of a round wooden tube of short length divided longitudinally, and 12 is the half of a glass tube fitted in the wood in such a manner that when two pieces of wood and two pieces of glass are placed together they will produce an insulator that can be readily connected with a wire by bringing the two parts together from the opposite sides of the wire to inclose the wire and then fastening the two parts of the insulator together.

The outside surface of the wood is spirally grooved, and the end portions of a wire 13 are coiled in such a manner that wire can be first placed on a line-wire 14:, as shown in Fig. 3, and the insulator moved longitudinally and rotatedinto the coil on the end of the wire 14: to be retained in the coil on the end of the wire, as shown in Figs. 6 and 7.

It is obvious the insulators can be made of glass complete in two separate parts, as shown in Figs. 3 and 5. It is also obvious that two insulators and two line-wires can be connected by means of one connecting-wire 13, that is coiled at each end at a point midway between two posts 15 and 16, as shown in Fig. 6. They can be put on at a post and by force of gravitythey will slide to a central position between the posts, as required, to'retain the line-wires separate from post to post.

To connect pairs of line-wires, as shown in Figs. 6 and 7, a wire 17 of suitable length is coiled at its ends around the externally spirally grooved insulators, or the ends of the wires 13 on the insulators may be connected with flat pieces of wood or other suitable material, as shown in Figs. 8 and 9.

Having thus set forth the purpose of my invention and the manner of constructing the insulators and connecting them with line-wires and with each other, the practical operation and utility thereof will be readily understood by persons familiar with the art to which the invention pertains.

hat I claim as new, and desire to secure by Letters Patent. is

1. An insulator for telegraph line-wires consisting of two parts of rigid insulating material semicircular in cross-section fitted together to produce a short tube having a longitudinal bore in its center extending from end to end to admit a wire conductor in the manner set forth, a spiral groove in its out side surface and a wire coiled in the groove, for the purposes stated.

2. An insulator for telegraph-wires com= posed of a wooden tube having a longitudinal bore and a spiral groove on its outside surface and divided longitudinally into two mating parts and a glass tube divided longitudinally and fitted in the bore in the wooden tube for the purposes stated.

3. In the insulation of telegraph line-wires, two line-wires, two insulators composed of two mating parts provided with longitudinal grooves extended from end to end and provided with spiral grooves on their exterior surfaces and a wire coiled at its ends on the spirally-grooved insulators,arranged and combined as set forth for the purposes stated.

4:. In the insulation of a plurality of telegraph line-wires, two pairs of parallel line- Wires and each wire in each pair inclosed in an insulator-tube having spiral grooves on its outside and the wires in each pair connected by the ends of a wire coiled on the insulators and means for connecting the pairs of Wires, arranged and combined in the manner set forth.

5. An insulator for telegraph-wires composed of a Wooden tube having a longitudinal bore and a spiral groove on its outside surface and divided longitudinally into two mating parts and a glass tube divided longitudinally and fitted in the bore in the Wooden tube, for the purposes stated.

6. An insulator for telegraph-wires composed of a tube having a longitudinal bore and a spiral groove on its outside surface and divided longitudinally into two mating parts. a wire, coiled at its ends, in combination with the tubular insulator, a line-Wire, and wires for connecting pairs of line-wires extended through the insulators,for the purposes stated.

7. An insulator for telegraph-wires com posed of a tube having a longitudinal bore and a spiral groove on its outside surface and divided longitudinally into two mating parts, a wire, coiled at its ends, in combination with the tubular insulator, a line-wire and means for connecting pairs of line-wires extended through the insulators,for the purposes stated.
