WIRE-TWISTING IMPLEMENT.

Specification of Letters Patent.

Patented Dec. 6, 1910.

Application filed March 9, 1910. Serial No. 548,232.

To all whom "it may concern:

Be it known that I, AUGUST KAsI-An, a citizen of the United States, residing at Shiner, in the county of Lavaca and State of Texas, have invented a new and useful Wire-Twisting Implement, of which the following is a specification.

This invention relates to wire twisting implements, and the object of the invention is to provide a tool of simple construction by which the manufacture of woven wire baskets may be facilitated. This object is attained by the use of the device illustrated in the accompanying drawings, and the invention consists in certain novel features thereof, as will be hereinafter first fully de scribed and then more particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a perspective view of a tool embodying my invention showing the same arranged to twist a pair of wires. Fig. 2 is a view showing parts of the tool in longitudinal section and other parts in side elevation. Fig. 3 is an enlarged transverse section on the line 3-3 of Fig. 2. Fig. 4 is a detail end View of the bit. Fig. 5 is a detail plan view of the active end of the bit.

In carrying out my invention, I employ a hollow handle 1 having open ends and provided at or near its front end with guides 2 which, in the present instance, are illustrated as consisting of rollers 3 mounted on pins a, secured rigidly within the wall of the handle. These rollers are spaced slightly apart and a spirally twisted shank 5 is engaged between the same so that if the handle be moved longitudinally with respect to the shank, the said rollers will ride upon the shank so as to impart a rotary motion to the same and to the bit 6 secured to the front end thereof. In order to limit the movement of the parts and to prevent disengagement of the same, stops 7 of any desired or convenient form are provided at the rear end of the shank, which are adapted to impinge against the guides 2 and thereby arrest the movement of the handle in the operation of the tool. The device may be thus made to automatically determine the length of the twist imparted to the wires by the tool, and a series of tools having shanks of different lengths may be provided in order that a twist of any desired length may be imparted to the wires.

'To the front end ofthe spiralshank 5, I

secure the bracket or jaws 8 which are provided with lateral lips or stops 9 adapted to engage the front end of the handle and thereby prevent the handle being carried so far forward as to be released from the shank. Between the jaws 8, I secure the bits (3 and the ends of the jaws are provided at their o posite sides with lugs or teeth 10 adapted to engage the opposite sides of the bit and thereby prevent pivotal movement of the bit upon the securing bolt 11 by which it is held between the aws.

The bit consists of a substantially rectangular body having its outer end shaped to present the wire-engaging lips 12. These lips converge from the opposite sides of the bit toward the free end of the same, and, as shown in Figs. at and 5, are in the form of oppositely-disposed hooks adapted to engage the diverging strands of wire, indicated at 13, so that when rotary movement is imparted to the bit from the shank,the wires will be caused to wrap around each other and thereby produce the spiral twist 14. Each of the ribs or hooks 12 projects forward from a wall 15 which extends obliquely from the side. of the bit toward the end of the same, and the edge of the projecting portion rises above the body of the same substantially parallel with the said inclined wall and thereby forms a groove 16 in which the wire will be seated, as clearly shown in Fig. 1. The groove on one side opens upwardly and on the other opens downwardly.

The handle is substantially cylindrical except at the front end where it is enlarged in diameter to there reinforce it, and this enlarged end slopes or expands rearwardly. The handle is of such length as to entirely house the spiral portion of the shank when the latter is in the retracted position, and

this long handle and also the expanded front end serves to direct long wires away from the operator, so that the twisting of the wires may be performed without danger of the long ends striking the operator.

In operating my improved tool, it is necessary merely to engage the bit with the diverging wire strands, as shown in Fig. 1, and then exert a slight pull on the handle sufficient to move the same longitudinally toward the rear end of the shank. The shank will thus be rotated so that the bit will be caused to twist the wire strands around each other, as will be readily understood, and this movement will be continued until the guides 2 at the front end of the handle impinge against the stops 7 atthe rear end of the shank, it being understood that the lips 12 engage the wire strands with sutiicient firmness to prevent the bit being drawn therefrom when movement is imparted to the handle. The wire strands are secured together to form the bottom of the basket or the initial loop of a wire fence fabric or other woven wire fabric in any desired manner, and the branches of the doubled wire are engaged by the bit so that the twisting of the wires and the production of the finished fabric may be rapidly accomplished with very little labor.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood, that the device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claims appended hereto.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is

1. A wire twisting tool provided with a handle, a twisting head, and a spiral shank for the twisting head, said handle being of a length to entirely house the twisted end of the shank when the latter is in the re tracted position.

2. A wire twisting tool provided with a handle, a twisting head, and a spiral shank for the twisting head, said handle being of a length to entirely house the spiral end of the shank when the latter is in the retracted position, the handle being of tubular form with the end through which the shank moves reinforced.

3. A wire twisting tool provided with a handle, a twisting head, and a spiral shank for the twisting head, said handle being of a length to entirely house the spiral portion of the shank when the latter is in the retracted position, the handle being of tubular form with the end through which the shank moves reinforced, and expanding rearwardly.

f. A wire twisting tool provided with an elongated tubular handle, a spirally twisted shank adapted when retracted to have its twisted portion entirely housed in said handle, means in the handle for imparting r0- tative movement to the ,shank on the movement of the latter longitudinally of the handle, and a socket member fast to the front end of the shank.

5. A wire twisting tool provided with an elongated tubular handle, a spirally twisted shank adapted when retracted to have its twisted portion entirely housed in said handle, means in the handle for imparting rotative movement to the shank on the movement of the latter longitudinally of the handle, a socket member fast to the front end of the shank, and a stop member carried by the shank in predetermined position thereon.

6. In combination with the hollow handle, rollers mounted on pins secured within the wall of the handle, said rollers being spaced apart, a spirally twisted shank engaged between the rollers, and stops provided on the ends of the shank.

7. A wire twisting tool comprising a twisting bit, a socket member adapted to receive said bit, a spirally twisted shank fast to the socket member, and an elongated handle of greater length than the twisted portion of the shankand adapted to completely house the same when in the retracted position, said handle being provided with guiding means for the shank to impart rotative movement thereto on the longitudinal movement of the shank.

8. A wire twisting tool comprising a twisting bit, a socket member adapted to receive said bit, a spirally twisted shank fast 7 to the socket member, and an elongated handle of greater length than the twisted portion of the shank and adapted to completely house the same when in the retracted position, said handle being provided with guiding means for the shank to impart rotative movement thereto on the longitudinal movement of the shank, the handle having the end receiving the shank enlarged in diameter and externally expanding toward the other end of the handle, and the handle eX- cept at the enlarged end being substantially cylindrical throughout. 4

9. A wire twisting tool comprising an elongated handle, a spirally twisted shank having the spiral portion when retracted entirely housed within the handle, means at the end of the handle into and out of which the shank moves for imparting rotative movement to the shank, means oarried by the shank for determining the distance of projection of the shank from the handle, and a socket member for a twisting tool carried by the shank, said socket mem ber comprising jaws each of which is formed at the rear end with a lateral lip adapted to engage the corresponding end of the handle member to limit the ret-raetive movement of the shank.

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