TOOL FOR LINEMENS USE.

SPECIFICATION forming part of Letters Patent No. 530,361, dated December 4, 1894.

Application filed September 17,1894. Serial No. 523,262- (No model.)

To aZZ whom it may concern.-

Be it known that we, SOLOMON SMITH and MILTON B. MISHLER, citizens of the United States, residing at Ravenna, in the county of Portage and State of Ohio, have invented certain new and useful Improvements in Tools for Linemens Use; and we 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 is an improved tool for telegraph linemens use.

Heretofore, the main line wire has usually been connected to an insulator by means of a short piece of wire passed around the insulator andthen twisted around the main line wire. This form of connection has been found objectionable, because it takes a great deal of time to put the fastener on, or take it OK, and then the wire is not fit for use more than once as it becomes broken by twisting and untwisting around the main line wire. To avoid these objections several forms of wire loops have been devised for connecting the main line wire of the insulator.

The object of this invention is to provide a tool which facilitates and expedites the operation of putting these loops on, or taking them 0%. 4

The invention, therefore, consists of a hand lever slotted at one end, which slot extends some distance up the length of the handle and a double hook pivoted within said slot, said hook being held in its proper position by means of a spring also connected with the handle and bearing on the hook.

Our invention consists also in certain details of construction and novelties of combination, all of which will be fully described hereinafter and pointed out in the claim.

In the drawings, forming a part of this specification, Figure 1 is a view showing the tool used for putting the loop on. Fig. 2 is a similar View showing the tool as used in removin g the loop. Fig. 3 is a longitudinal sectional view.

In carrying outour invention we employ a lever or handle, A, which is shaped at one end to fit the hand as shown at a. At the opposite end is produced a longitudinal slot B, which extends some distance up into the handle, and within the slot near the upper or inner end is pivoted a double hook O, which is essentially crescent shape and formed with hooks c, c, at each end. This hook is pivoted at a point at one side of the center so that one arm is longer than the other. The edges of the slot are cut away as shown at d, (1, adjacent to the short arm of the hook, for the purpose of receiving the round head of the insulator, when using the tool to take the loop off, and upon the opposite side of the lever, near the end of same, are produced the notches, d d which are intended to receive the lower edge of the insulator when the tool is used for putting the loop on.

Arecess D is formed at the head of the slot adjacent to the long arm of the hook, and in said recess is arranged a spring E, said spring comprising a coil 6, arranged upon a pin e, passed through the lever, and a loop a which bears against the long arm of the hook and holds the same in place, while the tool is being used to put the loop on.

If desired the hook may be made with a series of perforations to receive the pivoted bolt and in this manner the length of the arms can be varied to suit the size of loop or insulator.

A stop pin F, is passed through the lever near the short arm of the hook to limit the movement of said hook. Now the loop may be of any kind provided it can be attached to the wire and then drawn over the head of the insulator. To attach the loop to the insulator the notched end of the hand lever is placed under the edge of insulator; and the long arm of hook brought into engagement with the loop. The hand lever is then thrown down carrying with it the loop which springs into the groove in the head of the insulator.

To remove the loop, the out out portion of the lever rests upon'the head of the insulator and the short arm of the hook in engagement with the loop. The lever is then moved upward and the loop is sprung from the insulator thus avoiding all bending and twisting of the wire.

The tool can also be operated with one hand so that the lineman can use the other tosteady himself and the line wire,

Having thus described our invention, what we claim is- A tool comprising a lever slotted at one end and cut away on one face and notched on the 5 other, a double hook pivoted within the slot,

and a spring bearing upon the hook, substantially as shown and described.

In testimony whereof we affix our signatures in presence of two witnesses.
