WIRE-TWISTING TOOL.

SPECIFICATION forming part Of Letters Patent No. 471,419, dated March 22, 1892. Application filed July 13, 1891. fierial No. 399,363. (No model.)

To all whom it may concern:

Be it known that I, AARON F. DICKEY, of Friedens, in the county of Somerset and State of Pennsylvania, have invented certain new and useful Improvements in Wire-Twisting Tools; and I do hereby-declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in wire-twisting tools which is intended especially to be used in connection with the construction of fences; and it consists in the particular construction which will be fully described hereinafter, and particularly referred to in the claims.

The object of my invention is to produce a tool for twisting the ends of wires either for the purpose of splicing them together or for the purpose of securing a main wire to a picket or post by means of a small wire which passes around the picket or post and then has its ends twisted around the main wire, or by means of which tool springs can be quickly and readily formed.

Figure 1 is a perspective view showing the tool applied to the wire for securing a picket in place. Fig. 2 is a detached perspective view of the tool. Fig. 3 is a central longitudinal sectional view of Fig. 2.

A represents a iiat piece of metal of any desired thickness or length, according to the thickness of the wire it is designed to twist. Each end of this flat piece of metal A is reduced for the purpose of forming the inclined shoulders 13 at each side of the reduced portion. The reduced portion of each end of the piece A is bent into a hook O, as shown, and these hooks preferably, though not necessarily, extend in opposite directions, so that the tool is more convenient to be applied to the wire.

lVhen it is desired to use the tool, one of the hooks O is passed over the main wire D, as shown in Fig. l, and the end of the wire E which is to be twisted is placed in one of the inclined notches which are formed by the shoulders B.

In use the hook 0 should be placed over the wire with the hook from the operator, and then by bearing down upon the opposite end of the flat piece A and turning it around the main wire the wire which is being twisted can be carried around as many times as desired. In this manner the wire is twisted very closely around the Wire it is being turned around and without any particular care or effort on the part of the operator. Owing to the shoulders being formed upon opposite sides of the reduced end portions and owing to the shoulders being thus formed at opposite ends of the piece'A the tool is ready to be used in almost any position it is taken into the hand without any further adjusting, as will be readily understood.

In order to prevent the tool from dropping off when being used in an elevated position, or under any other circumstances from becoming accidentally detached from the main or other wire around which the hook is passed, I provide a holding spring or look G. The lower end of this spring is secured rigidly to the flat portion of the piece A upon the side on which the hook is formed, and its upper end projects under the hook, as shown.

When the tool is applied to the wire, the wire passes in between the inner face of the hook and the outer face of the spring and fits in the curved or bent portion L of the spring G, as shown, which holds the tool to the wire against accidental displacement. As shown, I provide one spring for each hook, and which are preferably secured to opposite sides of the piece A.

For the purpose of cheapness in the construction of the device,l have the lower ends of the spring to reach to the same point upon the piece A, except preferably on opposite sides, and then secured by a single rivet N, which passes through the piece A and bot springs G.

This tool is also especially adapted for the purpose of forming spiral springs of any desired size by wrapping them around a larger wire or core which is the diameter which it is desired the spiral spring shall have when bent into a hook, a shoulder at one side of the hook, and a holding-spring which has its inner end secured to the flat piece of metal and its free end extending under the said hook and bent to form a holding-shoulder, substantially as set forth.

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