G. ASHBY. INSULATOR FOR WIRES.
No. 588,048. Patented, Aug. 10,1897.

GEORGE ASHBY, OF HAMILTON, CANADA.
INSULATOR FOR WIRES.
SPECIFICATION forming part of Letters Patent No. 588,048, dated August 10, 1897.
Application filed December 24, 1896- Serial No. 616,373- (No model.)
To all whom it may concern.-
Be it known that I, GEORGE ASHBY, a subject of the Queen of Great Britain, residing at Hamilton, Ontario, Canada, have invented certain new and useful Improvements in I11- sulators for IVires; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention has reference to a novel construction in a wire-insulator, the object being to provide more especially an insulator for the cross-arms of telegraph-poles that is of simple and inexpensive construction and to which the telegraph-wires can be quickly attached and removed.
The invention consists in the features of construction hereinafter described and claimed.
In the accompanying drawings, forming a part of this specification, Figure 1 is a side elevation of a portion of a cross-arm provided with an insulator constructed in accordance with this invention. Fig. 2 is a central vertical section of the same. Fig. 3 is a side elevation illustrating a modification.
Referring now to said drawings, 1 indicates the cross-arm of the telegraph-pole, and 2 the said insulator. The insulator consists of a screw-threaded stem 3 to be screwed into the cross-arm and with the uprising fingers 4, between which the insulator 5 is secured. One of the uprising arms a is provided with a lug 6 at its upper end, which is adapted to hold the telegraph-wire in position while the lineman is getting ready to secure the same to the insulator. The said insulator consists of a cylindrical piece of glass or other non-conducting material having a central groove 7, adapted to receive the telegraph-wire 8 and the tie-wire 9 in the manner shown. As a preferred construction the said non-oonducting insulator 5 is held between disks of wood 10, having bosses 11, fitting into recesses 12 in the ends of the insulator. From the inner ends of these disks or plates 10 are the inwardly-extending tubes 13, which interfit at their inner ends inside of the opening 14: through the insulator 5. These wooden disks or plates are placed 011 the outside of the insulator, and the parts are screwed in place by means of a bolt 15 in the manner shown.
\Vhen it is desired to use an insulator of this construction upon awall or other upright place, the stem 3, by which it is screwed, can be provided with an extension, which serves as the bolt 15, that passes through the wooden tube 13, while an arm at is situated between the insulator and the stem, said arm being also provided with a lug 6, as before described.
An insulator constructed in accordance with this invention is not only simple and durable, but can be made of small dimensions and can be readily applied or removed, while at the same time the telegraph-wire can be quickly attached thereto or removed there from.
Having thus described my invention,what I claim as new, and desire to obtain by Letters Patent, is
1. An insulator consisting of a stem provided with an arm at having a lug 6, a bolt 15 connected with said stem, and a cylindrical piece 5 mounted upon said bolt, substantially as described.
2. In an insulator, the insulator 5 consisting of a cylindrical piece provided with an exterior groove, end recesses, and a central opening, and disks 10 situated on either side of said insulator 5 and provided with bosses 11 situated within said recesses, and tubes situated within said opening, substantially as described.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
GEORGE ASHBY.
