WIRE rrwisrnia.

Continuation of application Serial No. 758,066, fiIed DecemberZG", 1924.

' 24, 1925. Serial No.7 77,450.- I I ,This invention relates to wire twisters and the like, and is a continuation of my appl1- -Another object of the invention is to pro-,

twisting with a pan. f' lj mak vide a simple and inexpensive tool for stretching the wire taut, and then twisting the ends thereof to hold the forms securely in place.

A further object is to provlde a tool by means of which the form wiresccan be stretched and twisted from the outside of .the forms, eliminating the necessity of the workman crawling into the space between the forms, and twisting the wire tight with. .a short stick, or other. suitable implement.

A still further object is to design a wire twister provided with release mechanism to allow the tool to quickly and easily release;

the wire. 7

A further object still is to provide atool for use in twisting the wire on packing boxes.

The above and otherobjects will appear as the specification progresses, reference being had to the accompanying drawings in;

which like reference numerals indicate like parts throughout the several views thereof Fig. 3 is an: enlarged part sectional side I view. of the head and jaws, the release mechanism being shown in two different positions. I

In the ordinary labor of erectingforms Ficr. 8 is a sectional view of onewof'the; I I

' projects beyond theca'sin'g, and is adapted for retaining walls, foundation walls, columns,.and.1n fact forms ofany nature into "This application fil ed ne ceniber whiehconcrete is: poured, it is customary to provide spaced'apart wire or rods, either threaded or clamped by various external devices to prevent the forms spreading, due

to theweigl'it of the'concrete. Thi'sis usually done by drilling holes through the form lumber on eitl ier side of one of ,thevertical studs and passing a strand of wire therethrough, bringing the ends together and thewires taut. It is then necessary for the workman to get into the space between the forms, and with a hammer handle or other implement, twist the strands ofwire unor column. It further permitslofthe quick and'e asy. displacement and removal of the usual'spacer members Which are inserted directly ad acent each wire in wall form work,.thereby eliminating the necessity ofv additional wires which ordinarily remain in place until the concrete is'set.

flleferring now particularly to thedrawings in, which Iliae shown the preferred embodiment of my invention, the numeral 1 indicatesahollow tubular barrel or casing,

having an offset downwardly projecting leg or portion 2 formed integral therewith, the

end of;which terminates in a curved shoe 3 adapted to engage" one edge of the vertical studding, column or the material of whicl the form or box is constructed. i

.A shaft 4 extends through and is :re'volubly mounted in this tubular barrel. 1, a. crank member 5 beingpinned,jkeyedor otherwise secured to the upper. end thereof, and a hiter-ally projecting handle 5 iscsecnred to the opposite end of the crank in any approved 'lheoppositeendof the shaft lis threaded,

to be introduced into a threaded opening 4 provided in the head 6. and whiclris locked Oppositely disposed lugs 7land,8 are cast integral with and project from opposite sidespresently described.

Another offset lug 9 is formed integral with the head and at the lower end-thereof, and a pair of spaced apart jaw members 10 are pivotally secured thereto by means of a pin member 11, said jaws being formed as clearly shown in Figs. 6 and? of the drawings, and straddle the lug member 7 a rib or side wall 12 being formed on the outer edge prising abarr-el having an offset leg formed of each jaw, and preventsdisplacement of the wire. v

A pair of individual cam shaped jaws 13 are pivotally secured to the opposite lug 8 by means of the pin is, the face or jaWhaving small teeth which cooperate with the. jaws 10 for gripping the wire and preventing slippage thereof, cotterpins 15 being inserted through the pins to prevent dis-' placement of the, wire. The pivoted jaws 10 are held in position 'by means of's'paced apart cam shaped lugs 16 mounted on a pin 17 which is journaled in the member 7, a release lever 18 being cast integral with said lug members to facilitate the release of said jaws when it is desired to release the tool from the wire. A flat resilient spring member 19 is secured to the forked jaw '10 by means of screws 20, and are forked as shown, the upper ends engaging'the cam shaped lugs 16 to hold them in proper position.

In practice the form wire is threaded through the forms or placed in position around a column form, the ends projecting as shown, the ends of the. wire are then crossed and placed in each respective jaw,

and the'shoe 3 placed in position against'one of the vertically disposed stud members or the corner of the column or box, a prying action is then exertedby the' operator in the direction as indicated by the arrow B, pulling the wires taut and the crank 5 is then rotated and the wire twisted until the desired tension is secured, the release lever 18 is then swung to position as indicated in dotted linesin Fig. 3, releasing the jaws 10 and allowing them to rock on the pivot and release the wire when the tool can be quickly and easily removed. 1

It will ofcourse be obvious that increased leverage on the outer end of the barrel pulls the wires taut and'jserves to more tightly elamp'the'wire between the jaws, and that releasing mechanism must be provided, oth- .erwise it would be very'difficult to disengage The fact that the twisting is accomplished 7 outside of the forms facilitates the inserting of a suitable tool between the wire strands for displacing the spacers (not shown) and removing them from the form.

From the foregoing description it will be obvious thatI have perfected a very sub-' stantial, simple and economical wire twister.

What I claim is I 1. A tool of the character described com- I prising a barrel having an oilset shoe'rigid thereon and projecting beyond the barrel,

a rotatable head journaled in thebarrel,

jaws pivotally mounted on the head, and means for revolving said head.

2. A tool of the character described com with a shoe, a head rotatably journaled in the barrel, pivoted jaws mounted thereon in pairs, releasable means for limiting the and means for movement of one set of jaws, revolving said head.

3. A tool of the c prising a barrel having an ofiset shoe, a head journa'led thereon, spaced. apart jaws pivotally mounted thereon in pa1rs, a release lever pivot-ally secured to said head and having a cam shaped head, resilient means mounted onthe jaws for holding one set of jaws in predetermined position, and manually operable means for revolving said head.

4:. A tool of the character described. comprising a tubular barrel having an offset and resilient means on the jaws and engage haracter described com- I ing said cam shaped end for'holding the lever in adjusted position, and meansfor rotating said head. i V

5. In a device of the character described comprising a barrel having'an offset downwardly projecting lug portion terminating 7 an a shoe, a shaft mounted m sa1dbarrel,f V v ahead secured thereon, spaced apart jilWS' pivotally mounted thereon in pairs, a release lever pivotally mounted onthe head and formed with a cam shaped head adapted to engage one set of jaws, and a lever formed integral therewith adapted to be manipu lated' to release said jaws, and a crank on the shaft for rotating said head.

6. In a device of the character described comprising abarrel' having a' downwardly projecting ofiset leg terminating in a shoe,

a shaft journaled in said barrel, a head detachably secured thereto and having offset lugs, spaced apart jaws pivotally mounted on said lugs'in pairs, means for holding one set of jaws in predetermined position,- and including a release lever having a cam shaped head adapted to be actuatedto release one set of jaws and allow fora limited' movement thereof, and a crank secured von the shaft for revolving the head.

7 A tool of the character described comprising a stationary barrel having an offset leg formed with a shoe integral therewith and projecting beyond the end of the barrel, a head rotatably journaled in the barrel, cam shaped jaws pivotally mounted thereon, and a crank on the opposite end ofthe head.

8. A tool of the character described comprising a stationary barrel having an ofiset leg formed with a shoe and projecting beyond the end of the barrel, a shaft revolubly mounted in said barrel, a crank on one end thereof, a head mounted on one end of the shaft, and comprising jaws pivotally mountedthereon and adapted to grip a wire, and

a'crank on the opposite end r'or revolving said head.

In testimony whereof I aflix my signature.
