"WARREN RAY THOMPSON,

COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF NEW JERSEY.
INSULATOR-SUPPORT.
Specification of Letters Patent.
Patented Nov. 1, 1910.
Application filed May 10, 1910. Serial No. 560,529.
To all whom it may concern:
Be it known that I, VARREN RAY THOMP- soN, a citizen of the United States, residing at Chicago, in the county of Cook and the State of Illinois, have invented new and useful improvements in Insulator-Supports, of which the following is a specification.
This invention relates to supports for insulators for electrical conductors, and relates particularly to supports of the typeorkind commonly known as cross arms.
Stated generally, the object of the present invention is to provide an insulator support of the cross arm type, which will be simple and relatively cheap in construction, strong, rigid and durable, and which will be effective for its designed purpose To this end an insulator support of my invention comprises the various features and details of construction hereinafter described and claimed.
Specifically, an important object of'the invention is to provide a strong, rigid and durable structure Without the use of separate braces, heretofore commonly used and which represent a large item of expense.
In the accompanying drawing, in which my invention is fully illustrated-Figure l is a. view of my improved support looking lengthwise of the conductor wires. Fig. 2 is a view thereof taken at right angles to the wires; and Fig. 3 is a top plan view thereof.
Referring now to the drawings, 1 designates electrical conductors or' wires, 3 the insulators to which the wires 1 are directly connected, 6 the cross arm supports which carry the insulators 3, and 12 the pole or other support to which the cross arm supports (3 are secured. As regards their general features, all of the foregoing parts are.
old and well known in the art and, excepting as hereinafter particularly. pointed out and described, may be of any usual or desired construction and will be readily understood by those skilled in the art from an inspection of the drawings, without a description .11 detail thereof.
The cross arm supports 6 consist of bars, preferably angle bars, connected to each other at one end, as by bolts or rivets 11, each of said arms 6 being adapted to be connected to the pole 12 between its ends, as by bolts or lag screws 10, the relation being such that the ends of said arms 6 will projectat opposite sides of said pole and such, also, that said arms will diverge lengthwise from their point of attachment tov each other in the direction of the length of said pole or support 1:2, when connected thereto.
\Vith the described construction, it is obvious that, when connected to the pole 12,
said arms will brace each other and will form a stifi and rigid structure, thus obviating the necessity for separate braces, and correspondingly simplifying and cheapening the construction, all in the manner-desired.
As shown, the arms (5 are connected to opposite sides of the pole 12, but my invention contemplates attaching said arms to said pole in any other desired relation.
Formed at the opposite ends of the arms 6, are seats to which the insulator pins at are adapted to be connected. As shown, said seats are formed by the outwardly project-- ing flanges of the angle bars forming the cross arm supports (3, said pins being secured thereto in any suitable manner, as by bolts or screws 5.
If desired, a ground wire 2 may be used to protect the conductors 1 from damage by lightning. Said ground wire *3 may be'convcniently supported on an upward extension 7 of the pole 12. consisting, as shown, of an angle bar of desired length connected to the upper end of the pole 12, by means of bolts or lag screws 8 and 9.
I claim I 1. An insulator support comprising bars connected to each other at one end. said bars diverging from their points of attachment to each other, so that their opposite ends will be separated, and said bars being adapted to beconnected between their ends to a pole or other support, substantially as described.
2. An insulator support comprising angle bars connected to eachother at one end, said bars diverging from their points of atachment to each other, so that their opposite cndswill be separated, and said bars being adapted to be connected between their ends to a pole or other support. substantially as described.
3. An insulator support comprising bars connected to each other at one end, said bars diverging fromtheir points of attachment signature hereto, in the presence of two witto each other, so that their opposite ends nesscs. will be separated, and said bars being adapti ed to be connected between their en 5 to op- VABREN RAY THOMPSON pcsite sides of a pole or other support, sub- 1 \Vitn ss s; stantially as described. A. H. SAYCE,
In testimony whereof, I haveaflixed my 1 EVERETT E. SANFORD.
