WIRE ruLLINe Ann TWISTING TOOL.

Application filed June 27,1927. Serial No. 201,787.

This invention relates to wire tightening Fig. 3} toward the wide part of the wedge I and twisting tools as used by the builders of wooden concrete forms preparatory to pouring-concrete into the forms, and particularly to such a tool as shown in my prior Patent #1,576,400 issued on March9th,-1926, being in fact an improvement on the tool shown in said patent. V

i The objects of:my improvementsare to provide to tool of the character described 7 which will be easier toassemble with thewire to be tightenedand twisted and which will be easier to operate than former tools. 7

In the drawings hereto Fig. 1 is a perspective view ofmy complete tool.

Fig. 2- is a front end view of the tool.

Fig. 3 is a plan view of the tool in position against the 2 x 4 brace ofa wooden concrete wall form showing the manner of inserting the tie wires to tie the form sides together.

Fig. 4; is a side elevation of'the tool as per Fig. 3 showing an intermediate or twisting position A and an upper and lower stretch ing or pulling position BC. I

Fig. 5 is a perspective view of a modified form of wire clamp.

Briefly described the tool comprises a double'j aw for gripping the two ends of a U wire which extend through the wooden concrete wall form on opposite sides of the usual 2 X 4 uprights, and a forwardly extending heel for fulcrurning against the upright for pulling or stretching the wires by an upward or downward movement of a handle extending from the shank of the jaws, alsothe handle being of crank or carpenters brace form to facilitate twisting of the wire by revolving the tool.

In the drawings the shank is shown at 1 and formed rearwardly into a carpenters brace or crank 2 preferably provided with revolvable sleeves at 3 and 4 so that the tool may be revolved without injuring the hands.

The shank is substantially flat on top and bottom and made with side edges flaring forwardly to form a Wedge, and-preferably with serrations or small teeth along the active portion of the edges as at 5.

A longitudinally extending slot 6 is pro vided in the wedge and through which extends a handle 7 having a grip 8 and the lower end of the handle provided with a cross arm 9 having two upwardly extending jaws 10 so arranged that they may be slid alongthe shank from position D to position E (see for freely slipping the wires in laterally as andthereby clamp a wire strand against each edge ofthe shank, the -teeth 5 assisting in preventing the wires from being pulled out.

At theforward end or base of the wedge shank is a forwardly and outwardly extend- :2;

.ing heel or fulcrum plate 11 projecting in practice abouta couple of inches in front of the wide end of the wedge, while at the juncture of thenheel 11 to the wedgeI provide a jecting offset. ends 12 and above and below which ends I provide projecting horns 13 spaced from the wings sufficient to permit the passage of a wire along the edges of the I wedge, the wings andhorns' beingslightly bent toward one another as best shown 1n Fig. 2 so as to form a retaining space for each wire. 1

In use the nose of the fulcrum is placed against the 2 X 4 brace 1a of one side 15 of the building wall form and the ends 16 of the tie wires 17 are slipped between the horns 13 and wings 12 and between the edges 5 of the wedge and jaws '10, after which the jaws are moved forwardly by means of the han- -wing OITtWlStBTflUg having. oppositely pro;

die 8 to the position E 7 so as to grip the wires firmly against the edges of the wedge,

and the wires if fairly tight may be twisted by means of the brace handle 3-4, or if not tight the tool is lifted to angle B (see Fig.

4) to fulcrum the heel against the brace 14 and forcibly stretch or pull the wires and i jacent the jaw portion F as it is not open are both jaws of the construction shown in Fig. 1.

.tates threading one of the wires through ad- 7 In Fig. 1 it should be remarked that the handle 7 fits loosely in the slot 6 so that the jaws are free to clamp both wires at the same time.

It would of course be possible to omit the V brace handle from the shank and simply extend the shank witha squared end as indi cated at G so as to go in a regular carpenters brace but the complete tool as shown is to be preferred as it is more adapted for the crowbaruse in pulling the wire as indicated in Fig. A at B and C.

After pulling the wires and twisting them to draw' the concrete form sides tightly to-' gether, the wire ends are easily released byv simply pulling the jaws back to the small part of the wedge by means of the handle V grip 8, a cotter pin shown extending through the handle keeps the jaws in the right relation to the wedge shank while permitting plenty of freedom 'for'wiggling the handle about to release the jaws or clamp'the wires.

I claim: 1. A wire tightener and twlster comprising a shank provided with a gripping member at one end'for engaglng the free ends ofa wire loop, a wing or lug projecting from the end of the tool so positioned that one 'wire lies beneath and the other above one end of the wing, and a horn adjacent each end'of the wing on the opposite sides ofthe wireends.

7 2.. A wire tightener and twister comprising a shank provided with a wedge plate at its end, a' pair of jaws slidably mounted on said whereby the wires may both be laterally slipped into position.

3. A wire tightener and twister comprising a shank provided with a gripping member at one end for engaging the free ends of a wire loop, and a fulcrum, heel member eX- tending outwardly and forwardly of the gripping member, and a pair of opposed devices under saidvheel'meniber betweenwhich the ends ofthe wire are adapted to be laterally slipped.

4. A structure as specified in claim 21in m which said wedge plate is provided with teeth along its edges for gripping the wire.

5. A structure as specified in claim 2 in whichsaid wedge plate is provided with a longitudinal slot and a handle slidable therein connected to said jaws for manipulating the same. 1 y
