T. F'. KING. INSULATOR FOR ELECTRIC WIRES.
.[Application filed Sept. 21, 1901.)
(No Model.)
UNITED STATES PATENT OFFICE.
THEODORE I KING, OF NASHVILLE, TENNESSEE.
lNSULAT OR FOR ELECTRIC WIRES.
SPECIFIGATIGN forming part of Letters Patent No. 707,429, dated August 19, 1902. Application filed September 21,1901. Serialllo. 76,062. (Nomodem T 0 (all whom it may concern."
Be it known that I, THEODORE F. KING, a citizen of the United States, residing at Nashville, in the county of Davidson and State of Tennessee, have invented certain new and useful Improvements in Insulators for Electric WVires, of which the following is a specification.
My invention relates to insulators for electric line-wires; and the objects of the same are to provide a device of this character which shall be simple in construction, which will permit the wire to be connected to the insulator in a simple and convenient manner, which will be reliable and eflicient in use, and which may be applied quickly. I attain these objects by means of the construction shown in the accompanying drawings, in Which Figure 1 is a side view of an insulator embodying my invention. Fig. 2 is a central vertical section through the same. Fig. 3 is a transverse section of the same.
In said drawings the numeral 1 designates the body portion of my insulator, said body portion being substantially circular in form. A groove 2 may be formed around the body portion. The upper end of the insulator is tapered somewhat, as at 3. A slot or opening 4 extends from the upper end of the insulator downward a suitable distance, where it terminates in a lateral extension 5. At the terminal end of the lateral extension 5 a vertical groove or orifice 6 extends entirely across the insulator to form a seat or bed for the wire. Upon the opposite side of the insulator a similar lateral extension 5 is formed, terminating in the groove or orifice 6. At the top of the insulator a flaring opening 7 is formed to permit the easy insertion of the wire into the slot 4-. At the lower end of the insulator a screw-threaded socket Sis formed, and extending through one of the side walls of the body portion 1 is an orifice 9, which communicates with the threaded socket S.
In applying my insulator the socket Sis screwed onto the stub or projection upon a telegraph-pole, and when nearly turned home the line-wire is inserted in the flaring opening 7, carried down the slot at, and when the bottom of said slot is reached by the wire the insulator is turned about a quarter of a turn toward the right until the wire reaches the orifice 6. A pin or screw may then be driven through the opening 9 to hold the insulator in place. The object of the vertical groove or orifice 6 is to permit a wire to rest in either the bottom or the top portion of said orifice, depending upon the direction in which the wire runs or the inclination at which the insulator may be attached to the telegraph-pole.
Having thus fully described my invention, what I claim is 7 An insulator having an opening, or slot, extending from its upper end downward, a
lateral slot extending outwardly upon oppo-- site sides of the insulator, said lateral slot terminating in a vertical orifice, or bed, for the wire, said orifice extending upwardly and downwardly upon opposite sides of said lateral slot.
In testimony whereof I aflix my signature in presence of two witnesses.
THEODORE F. KING.
