TREE INSULATOB.

Application filed November 19, 1924. Serial 1T0. 750,797.

The invention relates to insulators and has for an object to provide an insulator for supporting a line wire out of contact with trees or other obstructions in its path.

Another object of the invention is to provide an insulator in which the insulator body may be secured to a base member in more than one position, and is detachable therefrom to afford facility in installation.

The invention further consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the accompanying drawings: Fig. 1 is 15 an elevation of an insulator embodying the invention secured to a support in one of its mounting positions;

Fi 2 is an elevation of the. insulator in anot er of its mounting positions;

Fig. 3 is a side elevation of the insulator in the assembly shown in Fig. 1, parts be-.

ing broken away and parts being shown in se'ction; and

Fig. 4 is a top view of the insulator.

. In these drawings 10 indicates an insulator body and 11 a base member to which it is secured.

The insulator body is preferably square in cross section and has spaced projections extending slot 13 between t em. The projections are preferably in the form of hooks extendin in op to directions and have their enrfs space from the body of the insulator to form passages 14. A central.

' wire-receiving passage 15 is also formed in the insulator body and extends transversely of the insulator body preferablgsat right an es to the slot 13 and the hoo 12.

i reduced flat-sided shank 16 extends from the otherend of the insulator body, which is preferabl the shank to reduce age losses, as shown in Fig. 3. O poeite sides of the outer portion. of the s ank are still uced further red to f rm shoulders 17, and-an ening 18 extends transversely e shank the reduced ehouldervforming sides. -The base member llhas a threaded atwag m m r. 19 ca t orntherwise firmly sec j one end topmvent relative rota- The projecting portion oftlie attacha transversely to bring the wire through tticoated adjacent M ca .held to ether and may be assembled ing member is in the form of a lag screw or bolt, a lag screw being used when attaching the base member to wood and a bolt when attaching it to a metal support.

The other end of thebase member is provided with a pair of fiat-sided resilient projections 20 ,forming a fork engaging the shank of the insulator body and having aligned openings 21 to register with the opening 18 for the receptionof a bolt 22 recelvin a 'nut 23 for clamping the fork on the s ank.

When conditions make it desirable to use the assembly shown in Fig. 1, in which the insulator body and base member are aligned, the flat end edges 24 of the projections 20 abut against the shoulders 17 to prevent swinging of the insulator about the bolt, and in the assembly shown in Fig. 2, in which the insulator body and base member are at right angles, the fiat side edges 25 of the projections perform a similar function.

The base member is screwed into a tree or other obstruction from which it is desired to space the line wire 26, the..slot 19 of the insulator being preferably arallel with the wire when the assembly 0 Fig. 1 is used. The wire is then pushed into the slot and the insulator given a quarterturn the passages 14 into the passage 15 where it is held against removal.

When using the assembly of Fi 2', the line wire is turned into place on 51c insulator body, or the insulator body is removed from the base member for placement on the line wire, and is then replaced on the base member, which has been previously screwed it at some convenient place.

The device is particularly useful in guiding a free span of wire through the branches of trees, the insulator being readily secured to the branches to hold the wire out of contact therewith and being attachable before or after the wire has been strung. The insulator body andbase member are rigidly In either 0 two esitions which makes it possible to provi e either vertical or horizon" tal mounting of the base member while retaining the insulator body in the same position, and to vary the spacing of the wire from the support.

lVhile the insulator body is preferably formed of porcelain, it will be understood that it may be of moulded plastic insulating material.

What we claim as new and desire to secure by Letters Patent is:

1. An insulator for spacing line wires away from adjacent objects comprising a block of insulating material having a wireengaging head and a reduced integral flatsided shank provided with shoulders at opposite sides, an attaching member having a threaded projection at one end to enter a support and a parallel-sided fork at the other end engaging opposite sides of said shank, and a retaining member passing through said shank portion and fork for holding said block on said attaching member with portions of said fork abutting against said shouldersrto prevent relative movement of said block and attaching member.

2. An insulator for spacing line wires away from adjacent objects comprising a block of insulating material having spaced projections at one end to hold the wire when the insulator and wire have been turned with respect to each other and provided with a reduced integral shank at the other end affording shoulders, an attaching member having a threaded projection at one end to enter a support and a pair of spaced projections at the other end for engaging opposite sides of said shank, and means for holding said block on said attaching member with portions of said spaced projections abutting against said shoulders to prevent movement of said insulator block on said attaching member.

3. An insulator for spacing line wires away from adjacent objects comprising a block of insulating material having a wire retaining portion and an integral flat-sided shank portion with oppositely disposed shoulders, an attaching member having a threaded projection at one end to enter a support and a pair of spaced projections at the other end for engaging opposite sides of said shank spaced projections abutting against said shoulders, and a retaining member passing through said shank portion and said spaced projections for holding said insulator body to said attaching member. 7

An insulator for spacing line wires away from adjacent objects comprising a block of insulating material having a wire retaining portion and an integral flat-sided shank portion with shoulders on opposite sides thereof, an attaching member having a threaded projection at one end to enter a support and a pair of spaced projections at the other end for engaging the opposite shouldered sides of said shank portion, and a retaining member passing through said shank portion and said spaced projections for holding said insulator body to said attaching member, the edges of said spaced projections cooperating with said shoulders to retain said insulator block on said attachingmember in different angular positions. In testimony whereof, we afiix our signatures.
