- WIRE-WORKIN G APPLIANCE.

Specification of Letters Patent.

Application filed May 23, 1910. Serial No. 562,845.

To all whom it may concern:

Be it known that I, CHARLES K. VVoLF, a citizen of the United States, residing near Xenia, in the county of Greene and State of Ohio, have invented certain new and useful Improvements in lVire-Working Appliances, of which the following is a specification.

My invention relates to wire working appliances, and particularly to Wire stretching and splicing tools.

The object of the invention is to simplify the structure, as well as the means and mode of operation of such devices, whereby they will not only be cheapened in construction but will be efficient in use, easily operated, and unlikely to get out of repair.

A further object is. to provide such a tool which will be small and compact, adapted to engage the wire in such way as to obviate any possibility of slipping, and to embody in one tool with the wire engaging means, wire straightening and wire twisting means.

With the above primary and other incidental objects in view as will more fully appear in the specification, the invention consists of the features of construction, the parts and combinations thereof, and the mode of operation or their equivalents as hereinafter described and set forth in the claims.

Referring to the drawings, Figure 1 is a perspective view of the tool, Fig. 2 is a perspective view showing the application of the tool to the work. Fig. 3 is an end elevation of the implement. Fig. 4 is a perspective view, showing the application of the implement to the wire and the method of engaging it therewith. Fig. 5 is a perspective view showing the wire and implement interengaged. Figs. 6 and 7 are perspective views showing the implement used as a wire splicer or wire twister.

Like parts are indicated by similar characters of reference throughout the several views.

In constructing the device there is employed a bar a bifurcated at its extremity as at b and said slotted or bifurcated portion is upturned or bent to U-form thereby forming two similar adjacently located hooks 0 separated by the slot 7). The bar a preferably projects laterally beyond the hooks forming shoulders cl preferably inclined on the upper or working surface. At the end of the bar at opposite the hooks c is a link iment being indicated by darts.

or ring 6, in which to engage the pulling bar f which is fulcrumed on the post as shown in Fig. 3. The bar a may be provided with either one or two lateral shoulders (Z which are used for twisting or splicing, or if the device is desired only for pulling or wire stretching purposes the shoulders may be omitted entirely.

Referring to Figs. 4 and 5 the wire gis to be pulled in the direction indicated by the arrow. The implement is applied to the wire with the bar parallel thereto, the wire extending through the slot Z) and the device in a reverse position, or with the hook end in the direction the wire is to be pulled. The implement is then reversed while maintained in engagement with the wire as shown in dotted lines in Fig. 4, the path of move- This reversal of the implement causes the extremity of the wire to be bent to parallelism forming a bight or hook in the extremity of the wire about one of the hooks 0 of the implement as shown in Fig. 5. The slot '2) being but little larger than the diameter of the wire will prevent the bent portion of the wire yielding or slipping when subjected to strain. A

suitable pulling bar f is thrust through the link 6 and is fulcrumed on the post or in any other convenient manner, to pull the wire to the desired tension. After the wire has been secured the implement, by reversing its previous movement, is employed to straighten the wire and remove the bight or bend placed therein for pulling purposes. While in the drawing thedevice is shown as attached adjacent to the end of the wire, it is to be understood that it may be attached at any point throughout the length of the wire.

WVhen used as a twisting device or for splicing, the implement is engaged with the wire with the main strand thereof passing through the hooks 0 as shown in Fig. 6. The splice wire or the strand to be wrapped about the main wire is engaged by the shoulder at as shown in said figure and the implement is turned about the main strand as about a pivot. The inclination of the shoulder d provides an extended bearing surface for the splice wire, andcauses the splice wire to be bent more gradually than if the shoulder is formed substantially square. It is to be understood however that the shoulder (1 may be made more or less abrupt or without the inclination as shown in the drawings. If but one shoulder (Z is provided the device Patented Sept. 10, 1912.

will be equally serviceable, but the wrap of the splice wire can only be made in one direction, that is a right or a left hand wrap. By providing a shoulder on either side the implement is made more convenient, in that it can be employed to wrap the splice wire in either direction.

From the above description it will be apparent that there is thus produced a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportion, detail construction, and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

Having thus described my invention I claim;

1. As an article of manufacture, a wire stretching implement, comprising a bar having a slot extending inward fromone end thereof, forming parallel fingers, the sides of said. slot being substantially parallel throughout, and separated by a space substantially equal to the diameter of the wire to be operated upon, the parallel fingers formed by said slot being bent upon themselves throughout an arc of substantially one hundred and eighty degrees, having an intermediate space between the bar and fingers when so bent substantially equal to the diameter of the wire to be operated upon, the reversed portion of the fingers being extended somewhat beyond the strand of wire and removed from the wire engaged in the U-shaped bend.

3. As an article of manufacture, a wire working implement comprising a bar, parallel fingers projecting from the extremity of the bar bent upon themselves into U-shaped form and separated from each other by an intervening space substantially equal to the diameter of the wire operated upon, a shoulder on said bar adjacent to the U-shaped fingers, said shoulder being inclined to the plane of the bar and substantially tangential to the exterior periphery of the U-shaped bend of saidparallel fingers, and means carried by the opposite end of the bar to engage a pulling lever, substantially as specified.

In testimony whereof, I have hereunto set my hand this 20th day of May 1910.

CHARLES K. WOLF.
