UNITED-i stares Appliaton filed February 29, 1928. Serial No. 257,849.

This invention relates to wire tightening and twist-ing devices as used by the builders of wooden forms for casting concrete walls and the like, and particularly tothe type of such a device disclosed in my copending application filed under Serial No. 201,787 on June 27, 1927, ent-itled 'Vire pulling and twisting tool.

The objects of the invention are to provide a device of the character mentioned which will be easier to operate and which will more effectivelyclamp the wires to be pulled and twisted.

In the drawingsaccompanying this speci- Iicat-ion.Fig..1 is a perspective view of oneV form ofmy improved wire. twisting device with wire receiving jaws open.

Fig. 2 is a perspective view of another form of my improved wire twisting device with wire receiving jaws open.l

Fig. 3 is a side view of the forward end of the device of Fig. 1 with the near side wall of the upper jaw broken away, and with the jaws closed upon a. wire .dotted in place.

Fig. 4 is a side view of the forward end of the device of Fig. 4 with t-he jaws closed upon a wire dotted in place.

As with my previous disclosure in the copending application referred to my device consists of a carpenters brace-like implement, but instead of a bit chuck at the forward end it is provided with means for holding a pair of wire strands so that the wires may be twisted together upon turning the brace, and the tool is provided with a forwardly projecting noseI or heel so arranged that it may be placed against the studding or side of the wall form and used as a fulcrum for pulling the wires, before and at intervals while twisting the same.

The improvements herein consist principally of the provision of a pair of jaws for gripping thel wire ends and a handle for operating the jaws, by means of which any desired grip may be placed upon the wires and the handle locked in place.

In the drawings, both Figs. 1l and 2, the carpenters brace portion is shown at 1 provided with revolvable sleeves at 2 and 3 for grasping in the hands to operate like any common carpenters brace.

In Figs. l and 3 the forward end of the brace is formed into a shank 4 provided with a step or jaw 5 and a socket 6 to which a yoke like jaw 7 is pivoted by means of a bolt 8.

This jaw 7 is arranged to swing down over i 1,698,689 Parent carica.

the jaw 5 as shown in Fig. 3 and to clamp a wire, or pair ofwiresto be twisted. The

position of the wire when clamped is indi cated in the dotted lines 19 and it willv be seen that the wire is kinked substantially at` right angles in two places where it is gripped between

jaws

5 and 7.

A handle 9 extends from'the pivoted jaw 7 so that the jaw may be clamped upon or released from the wires, and the handle engages any of a series of ratchet 'teeth 10 formed on the brace to hold the jaws in clamped position. l

rIhe handle is preferably provided with a flattened portion at 11 adapted to engage' the ratchet teeth, andis ina-de of spring metal flattened at 12 so arranged as to yieldingly hold theportion 11 against the ratchet teeth. n Projecting forwardly and outwardly from the forward end 6 of the tool is the fulcrum nose 13, while projecting upwardly from end 6 is a horn 14v which functions as a separator for twostrands of wire held in the tool for twist-ing.

In Figs. 2 and 4 all parts from 1 to 4, and

9 to 13 described for Figs. 1 and 3 are duplicated here andfunction the same as for Figs. 1 and 3, hence bear the same numerals.

The difference in the construction of Figs. 2 and 4 isthat the upper jaw 15 is not of yoke forms, but has its ends projecting` freely at opposite sides of the upper jaw handle, and the lower jaw 16 is similarly formed so that when the jaws are open as shown in Fig. 2 the wires to be twisted together may be freely slipped in place from opposite sides instead of being poked longitudinally into place from in front of the tool.

In Figs. 2 and 4 the wires are kept separated by the lower end 17 of the handle which is pivoted to the shank bolt .18.

The wire pulling fulcrum 13 shown in Fig. 2 is reversely curved from that shown in Fig. 1 but functions the same as it provides a fulcrum for the device forwardly of the wire of the brace by a clamping jaws and outwardly from the `main ters brace frame with a shank at the forward end thereof7 a wire clamping jaw operatively mounted on said shank, an operating handle extending from said jaw, and ratchet ine-ans on said brace frame adapted to engage said f handle to hold said jaw 1n clamped position,

and clamping means on said shank cooperatingwith said jaw adapted to kink said wire in clamping the same.

2. A mechanics tool comprising,` a carpenters brace frame with a shank at the forward end thereofya wire clamping` aw operatively mounted on said shank, an operating handle extending,` from said j aw, and means on said brace frame adapted to engage said handle to hold said jaw in clamped position andvmeans on the forward end of said tool arranged and adapted to space a pair ofwires clampedvby said jaw.

3. A mechanicstool comprising a carpenters brace frame with a shank at the forward end thereof, a pair of wire clamping` jaws on the forward end of said shank, one of said jaws pivotally mounted on the shank so as to open and close with respect to the other, a

`hand lever extending rearwardly from the pivoted jaw for operating the same, and means on the brace frame portion arranged and adapted to hold the handle locked at various points of adjustment with jaws in closed position. 4. A mechanics tool comprising a carpenters brace frame with a shank at the forward end thereof7 a pair of wire clamping jaws on the forward end of said shank, one of said jaws pivotally mounted on the shank so as to open' and close with respect to the other, means for locking the jaws together, and one of said jaws extending forwardly and out* wardly beyond the other of said jaws.

5. A mechanics tool comprising a carpentcrs brace frame with a shank at the forward end thereof, a pair of wire clamping jaws on the forward end of said shank,` one of said jaws pivotally mounted on the shank so as to open and close with respect to the other, said jaws arranged in offset relation so as to puta kink in a wire gripped thereby. i i
