Be it known that ,I, J nnmin u pnoniit, f acitizen of the United States, residing at and State of (jhio, have invented certain new and useful Improvementsin Tools for 5 .Wires on High-Voltage Gir- 1 cuits, of which the following is a specifiwire in contact with the stem 1, carr ing a cation. w 0 This invention relates more particularly to a special tool designed for use in manipulating insulator tie-wires on high potential transmission lines, while the power 18 on the. line.

According to the commonly prevailing practice, the danger to the workmen, due to the high voltage carried, is too great to permit 0 changing or manipulating such tie-wires while the ower is on the circuit, thus necessitatin either waiting until the power is shut o in the ordinary course ofevents, as at night, or shutting down the power and stopping trafiic and other operations dependent on the line. For the purpose of overcoming these. difficulties, I have devised a novel form of tie-wire which may be wrapped around the power wire or unwrapped therefrom, while the ower is on the circuit. For the purpose ofmanipulating this improved tie-wlre, as well as for the purpose of removing an old type of tiewire, with perfect safety to the workmen, I

have devised the tool constituting the subject of the present application.

In order to more fully describe this invention, reference will be had to'the accompanying drawing, wherein- I F1 ure 1 represents a perspective view of one Eorm of my improved tool; Fig. 2 is a side elevation thereof, partly in section; and Fig. 3 is a perspective view showing the said tool in operation as manipulating an insulating tie-wire. 1

In the drawing, this tool comprises among other parts, a stem 1 which may be of metal or any other desired material, held at one end, by being screwed thereinto, or in any other suitable way, rigidly in an insulator 2, preferably of the high otential petticoat type. This insulator may be one of the usual commercial insulators of this t pe, in the upper end of -which is bored a ole 3 to receive the stem 1. The insulator 2 is carried by a. rod or handle 4, the upper end of which is specimens-b1 Letters 'toi'Z'in-"t Wapakoneta, 'in the countyof Auglaize; 7

I For the purpose of pulling or pushing operations 1n coiling or uncolling my improved tie-wire, around or from the power conductor, the stem of this tool is provided with a plurality of spurs 5, 6, 7 and 8, the spur 5 slanting in the direction away from t e operator, While the other spurs slant in an' opposite direction, the former spur beingemployed for pushing a wire away from the operator, while the latter spurs are for the purpose of pulling the wire toward the operator. 7

In Fig. 3, I have shown this tool in the act of operation in connection with my im-- proved tie-wire above referred to, wherein the tool is shown in the act of wrapping one of the ends of the tie-wire around the power wire, the spur 6 being atthis time, in use to pull the loop 9 of the tie-wire toward the When he has pulled this loop toward him as far as possible with the tool, he then pushes it in the opposite direction by placing the spur 5 against the loop. He then pulls the loop toward him again, by means of the spur 6 and by repeating this operation, wraps the tie-wire 10 around the stat- Patented Nov.26,-1912.

power-wire 11, as indicated.' The spurs 7 and 8 are merely for the purpose of manipulatingthe wire closer to the operator than would be convenient by means of the spurs 5 and 6. Obviously, an other desired number and disposition o spurs may be arranged on the stem 1.

It often becomes necessary to untwist one of the old or commonly used forms of tiewire, from the power wire, in making the repair, in which one of my improved tiewires is substituted. This oldform of tiewire does not have loops at their ends. Therefore, for the purpose of taking hold of the ends of this old tie-wire and untwisting them from the power-wire, my improved tool is provided w1thtwo or more openings 12 and 13. By slipping the end of this old tie wire in either of these openings, it may be uncoiled orunwrapped from the power wire and insulator.

For the purpose of removing small branches of trees, and other obstacles which may interfere with the manipulation of this tool, I provide the stem 1 with a saw 14, by

' which these obstacles may be readily removed.

While I have herein described this tool with special relation to its use in connection with the manipulation of tie-wires, it will be understood that the same is susceptible to various other uses in manipulatlng line wires on high potential transmission circuits.

Having thus fully described my invention, what I claim is:

l. A tool of the class described, comprising a stem having spurs thereon, an insulator on which said stem is mounted, and a rod to which said insulator is secured, the said insulator separating the said stem from said rod.

2. A tool of the class described, comprisin}: a stem having oppositely directed spurs thereon, an insulator on which said stem is.

mounted, and a rod to which said insulator is secured, the said insulator separating the said stem from said rod.

3. A tool of the class described, comprising a stem having oppositely directed spurs thereon, a high potential insulator of the petticoat type, on which said stem is mounted, and a rod to which said insulator is secured, the said insulator separating the said stem from said rod.

4. A tool of the class described, comprising a stem having a plurality of oppositely directed spurs thereon, one or more openings in the said stem adapted to receive the ends of wires, a rodforming a handle for said tool, and a high voltage insulator interposed between said stem and handle, substantially as described.

In testimony whereof I aflix my signature in. presence of two witnesses.
