To all whom it may concern:

Be it known that I, JAMES a citizen of the United States,

at Dayton, Campbell county,

H. WOODARD, and residlng Improvements in Wrenches; and I do declare the following to be a clear, full, and exact description of the invention, attention being called tothe accompanying drawing,

of the particular construction as hereinafter described and and as illustrated in the accompanyingdrawing, in which :5

Figure 1, shows thewrench in side-view" ready for use.

\ Fig.2, is a front-view of it, side where the object to be thespace between the jaws. Fig. 3, in a. view similar to Fig. 1, shows the showing that tool in a condition in which the adjustable I adjusted as it shows one of the mi-t' its rotation,

jaw maybe set to position with a sliding movement. Fig. 4, is a rear'view of the tool appears-in Fig. 3. Fig. 5, in a view similar to Fig. 3, shows it with parts broken away. Fig. 6, shows the tool from the same side partly in section and with parts removed. ,Fig. 7, in a detail-view manipulating parts.

In the drawing, A is the four-sided shank provided at .one end (with the stationary jaw B and inserted with its other end into a handle C. Part of one side of this shank, hereafter referred toas thefront side, is provided with a rack a pitched to form part of a screw thread.

-D is the adjustable jaw slidably mounted leeve d, which upon shank A by means of a. s forms an extended part of said jaw and is fitted to the shank and; around the four sides of the same. An externally threaded nut E is provided on this jaw in a manner to perand fitted to. rack a on the shank so that when rotated, jaw D may be adjusted to or from jaw B, and with reference to an object between them.

To permit jaw Dip be; moved through Specification of Letters Patent. Application filed July 18, 1908. Serial No. 444,245.

State of Ken'- tucky, have invented certain new and useful of quick-acting rat-elites oats, 1908.;

the range of its possible adjustmenfqu'ieker than .can be done with the 'screw-mo'veinent,

time nut E, is disengaged fromrack (teas-. j'aw'Dmay shown'in Figs. 3 and 5,so'tl ijat be quickly moved on shank A and set against,

the object to" be gripped. Thereafter-nut E, having been brought again' into' rengagemen-t with the rec is used to complete the adjustment to grip the object-.-' To permit this ad ustment of nut E with reference to rack a, the former is mounted upon. a pin F, which at f, is hingedlyconnectkd totheunderside of movable jaw D, and in amennerto permit it to swing towardsor'from' the front side thereon into or out of engagement with rack-a, For the purpose ofad'justing nut E in this. manner, I provide a cylindrical member G, which has a function akinto. 'thatof a rock shaft and is'called hereaftena rocker.. This member is mounted so as to move with: sleeve of shank A, and with--'nut E' d, it-being for such purpose confinedb'etween a semi-circular extension H, on the lower end of sleeve (1 and the rear side of'shank A, said extension forminga bearin -in whichthis rocker may be oscillated and is closed by the rear side of the shank.

Extension H, is slotted as vFigs. 4 and 6, to clear a thumbpiece'i, g, which projects laterally from best shown in which bearing the rocker'and rearwardly fromthe tool and serves for manipulation of the rocker. .Links -K are provided to connect the lower free pin F with this rocker, connected to each end of each side of pin F and there being a. link this latter, one on and at each end of the links is a jointed one,

a pin is being used to connect one end of'bothpins to the end of pin F. Pins or screws L,"

are used, one on each of the otherlendslliof these. links, to connect them to 'rocker Gg L, one in each endend [of I with shank A be-f tween them. The connectionin each caseice are eccentrically located withreference-to.

the" axis about which rocker G is as best shown inFigs. 5 and 6.

Since nut E occupies two extreme positions 'with reference to rack. a, that is, it is either in or out rocker G and its handle, cupy likewise two extreme positions. When, handle g, is turned down on the back of the oscillated,

of engagement with it, thumbpiece g, 00-

' shank, as shown in' Figs. 3, 4 and 5, rocker l G -is turned so in its bearing H that holes Z in its ends are closest to the shank which causes links K to push pin F away from the shank and nut E out of engagement with rack a. The adjustable jaw may now be freely and quickly moved on the shank to suit the size of the object to be gripped.

positions, a friction sprin \Vhen handle 9 is turned up on shank A, as

shown in Figs. 1 and 6, the turning of rocker below it and at its upper end by a shoulder e due to the enlargement of the upper portion of said pin. The peripheral edges of j this nut are serrated, grooved or knurled to facilitate its manipulation.

Having described my invention, 1 claim as new.

1. In a quick-acting wrench, the combination of a shank provided with a rack on its fr0nt-side and with a stationary jaw atone of its ends,a movable jaw provided with a sleeve fitted-tothe shank, a pin jointed at one of its ends to the underside of this jaw, a nut mounted thereon so as tobe opposite the rack on the front side of the shank, a cylindrical rocker, a bearing in which it is oscil'latably supported and whereby it is carriedso as to move with the adjustable jaw,

and links jointed at one of their ends to the free end of the pin mentioned and at their other ends to each end of the rocker, the connection to this latter being eccentrically with reference to the axis of its oscillation and whereby such actuation causes the nut to either engage or to leave the rack mentioned.

2. In a quick-acting wrench, the combination of a shank provided with a rack on its front side and with a stationary jaw at one of its ends, a movable jaw provided with a sleeve fitted to the shank and extended downwardly to form a semi-cylindrical bearing the rack of the shank and closed thereby, said bearing being provided with an outwardly open slot, a cylindrical rocker fitted to this bearing and confined between it and the back of the shank, there being a laterally extended thumbpieee on the rocker which projects outwardly through the slot in the bearing and whereby the rocker may be oscillated, a pin jointed at one of its ends to the underside of the movable jaw, a nut rotatably mounted on it so as to be opposite the rack on the shank, and links jointed at one of their ends to the free end of this pin and at their other ends, one to each end oi? the rocker, the connection to this latter being ,eccentrically with reference to the axis of its oscillation.

In testimony whereof, I hereunto allix my signature in the presence of two witnesses.
