SPECIFICATION forming part of Letters Patent No. 499,814, dated June 20, 1893.

A pplicationfiled October 1, 1892.

T aZZ whom it may concern:

Be it known that I, MORGAN WILLIAMS, of Aspen, in the county of Pitkin and State of Colorado, have invented certain new and usef ul Improvements in renches; and I do hereby declare the following to be a full, clear, and exact description of theinvention,such as will enable others skilled in the art to which it appertains to make and use the same.

This invention contemplates certain new and useful improvements in wrenches, and has reference more particularly to nut-wrenches applicable to various sized nuts.

The object of the invention is to provide'a nut wrench so constructed that the necessary leverage for efiecting the rapid and easy turning of a nut can be elfected by the use of but one hand of the operator; and to also render such a wrench applicable to nuts of difierent sizes.

The invention consists of a nut wrench having its shaft extended at right angles from the head plate and parallel with the nut-receiving compartment, the handle-end of said shaft being at an acute angle diagonal to the axis of rotation of said shaft, the outer end of which handle-end is near, but not on, a straight line with the operative point of the head plate.

The invention further consists of r. wrench the head-plate. of which has a series of different sized jaws and asquared socket, andashaft re novably held in said socket and extended outwardly therefrom, its handle end being bent at an acute angle, whereby the wrench can be operated with one hand.

- The invention also comprises the detail construction, combination and arrangement of parts, substantially as hereinafter fully set forth and particularly pointed out in the claims.

In the accompanying drawings:-l igure 1 is a view in side elevation. Fig. 2 is a face view of the head-plate. Fig. 3 isatransverse sectional view on the line x-m, Fig. 1. Fig. 4 shows a modification.

Referring to the drawings, A designates the head-plate, from the front face of which extend four right angular ears or plates a, forming an I... These ears or plates are located so as to inclose each corner of the plate A and they form four intermediate jaws or nut receiving compartments (1. between their par- Serial No. 447,471. (No model.)

allel members. These jaws are of diiferent sizes or widths so as to accommodate divers sized nuts. The four innercorners of these L-shape ears or plates are connected by plates at formed integral therewith, and thus a fifth nut receiving compartment a is provided. A hole or opening a is formed in head-plate A at about the center of each compartment, and a second series of holes a is formed in plate a said holes being designed to permit the ends or points of the bolts to pass therethrough. From the back of head-plate A prejects a square socket b which extends outwardly some distance. To this socket is secured one end of a spring plate I), the free end thereof having a shoulder 11 thereon which normally extends through an opening in socket b.

' B is the operating shaft, the main portion 0 of which is squared at itsinnerend and fits snug within socket b in which it is firmly held by the shouldered end of spring plate 1) [itting within a groove or recess d formed in said shaft. This shaft extends outwardly from head-plate A at right angles thereto, and is bent to form a handle I), which is at an acute angle to the main portion of the shaft. The angle or inclination of this handled end of the shaft is such that the extreme outer end of said handle is extended to near, but not on, a direct line with the jaws of the head-plate. Hencethe handle end of the shaft being diagonal relative to the axis of rotation of the shaft, the wrench can be readily operated by one hand, the outer end ofthe handle resting 'in the socket of the hand and permitting of the free and easy movement of the wrist.

The mannerof using myimproved wrench is apparent. The head-plate and shaft are united together in such relation that the nut receiving jaw of size corresponding to the nut to beoperated upon will be on the outer side of the operating shaft, that is, on the side directly opposed to the diagonal handle end. By applying the wrench to the nut, the operator effects the turning of the Wrench and nut by a simple movement of one hand, causing the shaft to revolve around the axis of the nut at right angles thereto. Should the bolt be longer than the depth of the jaw or compartment its end or point will readily pass through the hole in thebottom of said pertains.

jaw or compartment. ing of the nut has been accomplished and it is desired to more firmly bind the same (and likewise when a nut is first to be loosened) the wrench is turned so that the head-plate will face the nut andagradual turning of the latter can be effected, a greater leverage being obtained in this manner.

The advantages of my invention are apparent to those skilled in the art to which it ap- It will be specially observed that by providing a wrench with a handle-portion diagonal to the axis of rotation of the shaft a nut can be rapidly and easily operated upon and but one hand being required the wrench can be worked in comparatively small spaces since it occupies but little room. An other advantage lies in'providing a wrench of this character with a series of jaws or nut-receiving compartments; and it will be seen thatthe head-plate can be readily removed and turned so as to cause the proper sized jaw to occupy the necessary position relative to the shaft and nut. A wrench thus constructed is extremely simple and inexpensive and not liableto readily get out of order.

In Fig. 4: I have shown a slightly modified form of. my invention. The change consists in providing a single nut-receiving socket E which is preferably made integral with the shaft. ()ne side of this socket is cut away or left open, as shown at e, so that when a, greater leverage is to he applied to the nut for the purpose of driving it home or effecting the loosening thereof the wrench can be turned to admit the nut in said cut-away space. The operation of this form of my invention is similar to that first above described.

I claim as my invention 1. A wrench having its operating shaft extended at an angle from the headplate and parallel with the nut receiving socket, and provided with a handle portion diagonal relative to the axis of rotation of said shaft, the outer end of said handle portion being extended to near a direct line with the nut receiving socket, substantially as set forth.

2. A wrench having a head-plate provided with one or more jaws or nut receiving compartments, and the operating shaft connected After the rapid turn-.

said shaft, substantially as set forth.

4. The herein-described improved wrench, comprising the head-plate having a series of jaws or nut receiving compartments of different size, and a socket,the shaft fitted in said socket and having auouter handle end diagonal to the axis of rotation of said shaft, and the spring-plate for holding said shaft in said socket, substantially as set forth.

5. The herein-described improved wrench,

comprising the head-plate having a series of jaws or nut-receiving compartments of (litterent size, a square socket extending therefrom having a hole or opening, the spring plate attached to said socket and having a shoulder projecting into said hole or opening, and the operating shaft having a squared portion, provided with a groove or recess and held in said socket by said shouldered end of said springpla te, substantially as set forth.

6. The herein-described improved wrench, comprising the head-plate having a series of holes or openings therein, the angular plates projecting from said head-plate, the inner plates connecting said angular plates also having a series of holes or openings, the socket,

and shaft rigidly held in said socket and having its outer handle end diagonal to the axis of rotation of said shaft, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
