Description

HERBERT SINCLAIR, OF TRENTN, NEW JERSEY.
INSULATOR.
Specification of Letters Patent.
Patented May 28, 1907.
Application filed February 19,1907. Serial No. 358.199.
To all whom it may concern:
Be it known that I, HERBERT SINCLAIR, a. citizen of the United States of America, and residing at Trenton, in the county7 ofMerc-er and State of New Jersey, have invented a` certain new and useful ImprovedL Insulator, of which the following is a specification.
M invention relates more particularly to insu ators for electric wires of that class which are commonly known as knob linsulators, and the object of my invention is to rovide an inexpensive but eliicient insuator, which can be easily applied in the Stringing of the electric Wires.
In the accompanying drawings Figure l i a longitudinal section;b1' `ig. 2 -is a front view; Fig. 3 is a rear view; Fig. 4 is a longitudinal section in a plane 'at right angles to the view,
Fig. 1; Fig. 5 is a perspective view of the two parts ofthe insulator separated, one part be lng shown in section.
My insulator is made of two pieces of porcelain or other suitable insulating 'materiah one part A having a body slotted on its rear side to receive the insulated wire C, while the other part B is of the nature of a rin through which a part of the body A passes. refer to form the body A of an approximate y cylindrical form, and I form on the rear side a transverse groove or slot a to receive the wire, the leg a1l which is thus formed on one side of the' roove being shorter than the other leg a. hrough thls longer le is formed a hole running longitudinally lrough the body or the passage of the nail or screw S, by.u which the insulator is to be secured to the" wall or other foundationF. The cross-section of this leg a2 is of' approximately semicircular shape and the ring B is formed'with a corresponding hole b1 through its rear for the assage of the leg a, whlle at the ford) end the opening bin the ring is c 1indrical to receive the cylindrical part o the body as shown in Fig. 1,. /The rin B/which is interposed between the/'wire an the wall or other support is made'of such a length or to secure a better hold on the wire.
I claim as my invention 1. A knob insulator, consisting of two parts, one a body part grosved on its rear side to receive the wire and the other a ring into which said body part enters, the ring being interposed between the wire and the sup port for the insulator.
2. 'A knob insulator, consisting of two lparts,.one a body part grooved on its rear side to receive the wire with a long and a short leg on opposite sides of the groove, the other part being a ring into which said body part enters, and being interposed between the wire and the support for the insulator.
3. A knob insulator, consisting of two parts, one a body part grooved on its rear side to receive the wire and the other a ring into which the bodypart enters, the ring being interposed between .the wire and the support for the insulator, and the body part having a hole longitudinally through it for the passage ofthe securing means.
4. A knob insulator, consisting of two parts, one a body part grooved on its rear side to receive the wire with a long and ashort leg on opposite sides of the groove, the other part being a ring interposed between the wire and the support for the insulator, and having a passage through the rear tor saidA long leg, which itself has a hole for the passage of the securing means.
In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses.
HERBERT SINCLAIR.
