H. W. WISTNER. CONDUCTING WIRE SUPPORT AND INSULATOR.

UNITED STATES PATENT OFFICE.
HARVEY W. WISTNER, OF OGDEN, UTAH.
CONDUCTING-WIRE SUPPORT AND INSULATOR.
Specification of Letters Patent.
Patented Nov. 5, 1907.
Application filed tune 13.1906. Serial No. 321575- This invention relates to conducting wire supports j and insulators of the type employed [or supporting telegraph and other electric conducting wires and lor insulating the same at their points of connection with the en arms of pole, and has for its objects to produce actor which may be conveniently cng ged with the wire and the cross arm. one wherein the msulator will be securely lixed in the arm but may be readily rcinoved therelrom, and one whereby the conducting wire will be properly fixed to the insulator.
With these and other objects in view. the invention comprises the novel features of construction and com binat ion of parts more l'ully hereinafter described. 5' 1n the accompanying drawin s Figure 1 is a perspective view ol' 2. portion 01' a cr arm showing a conducting wire connected therewith by means of an insulator embodying the invention. Fig. 2 is a sectional elevation, the section being taken on the line 22 oi Fig. i. Fig. 3 is a perspective view of the insulator sh owing the sections thereof separated. Fig. l is a perspective view ol' the cross arm.
Tielerring to the drawings, 1 designates a support in the form 01 a Clos arm adapted for attachment to a telegraph, telephone or other pole or support and having a plurality oi transverse openings 2 internally threaded for the reception of the insulating lnembers 3 and each provided with an entrance opening -1 through which the telegraph or other conducting wires may be introduced into the openings 2.
The insulator 3 which iorms the subject-matter oi the ment with the threads within the opening 2 of the cross arm is of reduced size from said threaded portion to its rear end, thus presenting a reduced portion 12 and is provided at its forward end with a non-circular extension or projection 13 having a pair of its opposite parallel walls to be engaged by a wrench or analogous tool for .rewing the insulator into or removingit from the openin g 2, which is of reduced size throughout a portion of its length to receive the reduced portion 12 of the insulator and to form a stop shoulder 14 with which the corresponding shoulder on the insulator contacts when comparatively simple, inexpensive device of this charthe latter is entered in place, while disposed between the meeting faces of the sections 6 and 7 is a sheet 15 of rubber or other insulating material.
In practice, the conducting wire is entered through the opening 4 into the opening 2, after which the sections (5 and 7 ol the insulator are properly assembled on the wire and the insulator as a whole screwed into the opening 2, after which the ends of the wire 10, which is introduced through the opening 9, are coiled around the conducting wire, as seen in Fig. 2, thus to hold said wire against longitudinal movement. It is to be observed that owing to the insulator being provided with the reduced portion 12 it may be conveniently introduced into the opening 2 and that in the operation of securing the insulator lirmly in place, the portion 13 will permit ready engagement ol' a wrench or analogous operating tool.
Having thus described my invention, what I claim is:
In a device of the class described, the combination of a support having an opening of dill'erent diameters, and threaded in the portion 01' larger diameter and provided with a slot opening radially from the said opening, an insulator having cylindrical end portions of ditt'erent diameters and a thread on the inner end portion of larger diameter for engagement in the opening of the support and provided with an non-circular extremity, said insulator being composed of two parts having registering grooves l'or receiving a conductor and one sec tion having a longitudinal pa. e'e adjacent the groove thereof, and a tie wire extending through the passage and adapted to be fastened to the conductor passing through the insulator.
in testimony whereof, I atlix my signature in presence of two witness HARVEY W. WISTNER.
