INSULATOR-TROTECTOR.

Specification of Ietters Patent.

Patented A r. 4, 1916.

Application filed. November 2, 1914. Serial N 0. 869,960.

To all whom it may concern Be it known that I, AUGUST Jor-mson, a citizen of the United States, residing at North Mankato, in the county of Nicollet and State of Minnesota, have invented a new and useful Insulator-Protector, of which the following is a specification.

The present invention relates to improve ments in insulator protectors, one object of the invention, being the provision of an incasing member adapted to surround the usual porcelain or glass insulators now in use upon telephone and telegraph poles and to thus protect the same against breakage by thrown stones or objects, the same including a two membered casing adapted to surround the insulator and be held thereaway from by insulating material so as to reduce the liability of the short circuiting of the supported wire.

A further object of the present invention, is the provision of a novel construction of insulator protector, which is simple, inexpensive and durable in construction, and which is thoroughly efficient and practical in use.

\Vith the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings-I igure l is a side elevation of the present protector taken from the locked side thereof, dotted lines illustrating the position of the insulator therewithin. Fig. 2 is a side elevation of the same. Fig. 3 is a top plan view of the same. Fig. 4 is a view in elevation showing the two sections of the protector open. Fig. 5 is a top plan view thereof.

Referring to the drawings, the numeral 1 designates the insulator which is of the usual construction. The protector consists of the two sections 2 preferably made of metal and hinged together as at 3 with a permanent hinge upon one edge thereof, the opposite edge being provided with the respective sleeves 4 and 5 for the reception of the locking pin 6 which is insertible therethrough similar to the usual door hinges now in use.

Each section of the present device is slotted from the edge adjacent to the hinge of the members 4 and 5 transversely as at fr to a point centrally of the member where it terminates in the enlargement 8 which is surrounded by the insulation 9 so that the line wire 10 will not be affected. It will be noted that the slot 7 is at a pointabove the upper end of the pin 6 when the parts are assembled.

In order to support the protector away from the insulator 1 so that a dome member will surround the same and be out of contact therewith, a plurality of buttons 11 made of an insulating material, preferably cork, are attached to and carried upon the inner face of the sections 2 of the insulator protector and are so disposed as to engage the sides of the insulator 1 below the line wire 10, or as particularly illustrated in Figs. 1 and 2.

From the foregoing description, it is evident that the present insulator protector may be readily disposed upon the insulator 1 with the line wire 10 in position, it being simply necessary to slip the same upon the opposite side or from right to left as shown in Fig. 2, with the sections spread open as shown in Fig. 5, so that the slots 7 in the free portions of the sections will permit the line wire 10 at each side of the insulator to pass therein so that the insulated portion 9 thereof will surround the wire, with the insulated buttons 11 disposed upon the body of the insulator thereabout. \Vhen this is accomplished, the members 4 and 5 aline so that the locking pin (3 may be inserted from above an insulator to prevent any short circuiting of the current from the line wire 10.

lVhat is claimed is:

An insulator protector composed of two sections hinged together and adapted when swung together to inclose an insulator, the free portions of saidsections having transverse slots extending toward the hingefor receiving a Wire supported by the insulator when the sections are swung together to inclose the insulator, and means for attaching the free portions 01: said sections together.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.

AUGUST JOHNSON.
