WILLIAM A. MORTON, OF LOS ANGELES, CALIFORNIA.
INSULATOR.
Specification of Letters Patent.
Patented Sept. 17, 1907.
Application filed November 6,1906. Serial No. 342,297.
To all whom, it may concern:
Be it known that I, WILLIAM A. MORTON, a citizen ol the United States, residing at Les Angelcs, in the county of Les Augeles, State of California, have invent ed a new and useful Insulator, of which the lollowing is a specification.
This invention relates to insulators for electric wires, such as telephone, telegraph, electric light wires, etc., and its main object is to provide means whereby the wire may be readily secured to the insulator without the use ol' the usual wire binder.
In the accompanying drawings :Figure 1 is a vertical section ol the insulator, transverse to the wire. Fig. 2 is a side elevation, partly in section. Fig. 8 is a side view of a different form of the invention.
Referring to Figs. 1 and 2, l designates the body of the. insulator, ol glass or other insulating material and having a screw threaded hole 2 or other means for attachment to a support. The top of the insulator body may be rounded as shown. In the side of the body is a slot 3 extending inwardly to a cylindrical passage l, provided with screw grooves 5. A cylindrical retaining member (5 [its in said passage and is provided with a screw flange '7 to engage said groove, the member 6 be ing screwed into place in the passage for turning it. In one side ol' this member 6 is a longitudinal groove 8 parallel to the axis of the screw and to the slot 3. Member 6 is provided on one end with means for turning it for example a rib 9 be gripped byawrench or pincers.
In using the device the member 6 is turned to register with groove 3, the wire is inserted through the slot 3 into the groove 8, and the member 6 is then turned, for example to position where the groove 8 is at the bot tom or to the position where the said groove is at the side away from slot 3, as shown in dotted lines in Fig. 1. In either of such positions the l'riction o the screw flange and groove 8, 7, on one another will be such as to prevent turning back of the member 6 by pressure from the wire, the pitch of these screw parts being sulliciently stoop to resist such turning.
The slot 3 and passage 5 may be at the top of the insulator as shown in Fig. 3.
W hat I claim isz- 1. An insulator comprisingabody having a cylindrical screw threaded passage and a slot extending thereinto, and a cylindrical screw threaded member in said passage and having a groove extending" parallel to the slot in the insulator bcdy.
2. An insulator comprising a body having a screw threaded passage, and a slot extending thereinto, and a screw threaded member engaging in said passage, and having' a longitudinal groove.
In testimony whereof, I have hereunto set my hand at Les Angeles California this 24th day of October 1906.
