Eiwuwwtox RAY BALLIET, OF WEST HAZLETON, PENNSYLVANIA.
INSULATOR.
Specification of Letters Patent.
Patented Aug. 3, 1915.
Application filed May 27, 1914. Serial No. 841,320.
To all whom it may concern:
Be it known that I, RAY BALLIET, a citizen of the United States, residing at West Hazleton, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Insulators, of which the following is a spec1fication, reference being had to the accompanying drawings.
This invention relates generally to insulators, and more particularly to one of that type used in connection with poles that are designed to support electric lights, telegraph or telephone wires.
The object of the invention is to provide an insulator of this character, havlng a novel form of Wire seat, the same being so constructed that when the wire is disposed therein, it will be positively held against endwise movement, and in the event of the breakage of the Wire, that portion combined .with the insulator cannot become accidentally detached therefrom.
A further object is to provide an insulator having a wire groove provided with a part designed to impart an upward kink to the wire, and with a keeper surrounding the wire kinking portion of the groove and provided at its terminals with wire receiving seats disposed below the plane of the crest of the kinking portion, whereby to lock the wire firmly in position.
With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and arrangement of parts of an insulator for electric wires, as will be hereinafter fully described and claimed.
In the accompanying drawings forming a part of this specification, and in which like characters of reference designate corresponding parts: Figure 1 is a horizontal sectional view taken on the line 1-1 of Fig. 3; Fig. 2 is a view in side elevation, partly in section, and Fig. 3 is a View similar to Fig. 2, taken at right angles thereto.
The insulator, as usual, may be constructed of glass or porcelain, and is provided with an internally threaded bore, 1, com bined with the supporting arm of the pole. The insulator is provided preferably with a rounded head 2 terminating in an outstanding fiange 3, and extending from the flange inward and downward is a circumferential wire groove 4, the latter merging into the base portion 5 of the insulator, the walls of the latter being preferably straight, that is to say, parallel with the axis of the insulator.
On one side of the insulator, the bottom wall 6 of the groove 4c is provided with an upward curved portion 7 which constitutes a wire kinker, and surrounding this kinker is a keeper or guard 8 provided with terminal wire receiving seats 9, the upper wall of which is disposed below the plane of the crest of the kinker, whereby when the wire is forced into the seats 9, an efieotive lock will be presented which will be positive in preventing endwise movement of the wire relative to the insulator, and also any accidental disconnection of the wire from the insulator in case of breakage of the former. The upper edge 10 of the keeper is disposed a suflicient distance below the flange 3 to permit the easy insertion of the wire between the inner wall of the keeper and the groove 4:, and the keeper is of sufficient length to insure a circumferential bend in the wire that will serve as a second look to prevent any endwise movement of the wire.
The kinker may be constructed on a long or a short curve as may be preferred, and the keeper may be of any desired length, that is to say, may extend only slightly beyond the ends of the kinker, or some distance beyond the same.
The improvements herein described while simple in character, will be found thoroughly efficient for the purposes designed, and will coact in the presentation of a practical, durable and thoroughly reliable type of insulator.
Having thus described my invention, what I claim is:
An insulator having ahead provided with a wire groove, the lower wall of which is provided on one side with an upward curved wire kinker, and an upstanding keeper carried by the kinker at the outer marginal portion thereof and provided with terminal wire receiving seats disposed below the crest of the kinker.
In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
RAY BALLIET.
