WRENCH.

SPECIFICATION forming part of Letters Patent No. 531,71 5, dated January 1, 1 895.

Application filed March 23, 1894- Serial N 604,766. (No model.)

To all 1072 0721, it may concern.-

Be it known that I, JACOB 0. BROWN, of Elmira,in the county of Chemung, in the State of New York, haveinvented new and useful Improvements in Trenches, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to wrenches which are adapted to be adjusted to nuts of any size.

My object is to produce a wrench of such a description,dispensing with the ordinary long handle which is usual and common with monkey wrenches, and adapting the wrench more especially for use where it is desired to reach a nut in a deep recess; and to that end my invention consists in the several new and novel features and combination of parts hereinafter described and which are specifically set forth in the claims hereunto annexed. It

is constructed as follows, reference being had to the accompanying drawings, in which Figure 1, is a side view of the wrench, complete. Fig. 2, is a vertical section thereof. Fig. 3, is a cross section on line :c-a:, in Fig. 2. piece. Fig. 5, is atop plan view thereof.

Similar letters of reference indicate corresponding parts.

-A is the base forming the top of the complete wrench, constructed substantially as shown having handles a, and lateral flanges -b-, all cast integral with said base, provided with a central recess c, and opening d.

B is an oblong shell diminished in size approaching its lower end, the upper end adapted to fit over the flange b to which it is secured by bolts, screws, or in any other well-known way.

The shell ]3 is constructed internally substantially as shown in the cross section shown in Fig. 3, and G are the jaws adapted to travel longitudinally therein, their lower ends extending beneath the shell as shown at -eand may have their inner faces notched or not as desired.

-D is an operating piece having a threaded recess -fin its upper end, and adapted to move vertically within the recess -c, and is provided with lateral arms gat its lower end, slotted, as shown at -h for the purposes hereinafter set forth.

-i-- is a disk or washer secured rigidly to Fig. 4C, is a view of the jaw operatingthe shaft E said shaft having a thumb screw or handle at its outer end, passing down through the opening d and the operating piece --D for the purpose of moving vertically the said piece -D. The washer -i turns with the shaft -E against the upper end of the recess c.

j are screws or bolts secured to the upper end of the jaws --O, passing up through the slotways h and their upper enlarged ends engagingwith the top of the slotted arms .It will be observed that when the shank or shaft l'l is rotated, the operating piece D will be raised or lowered thereby, and inasmuch as the lower end is connected to the upper end of the jaws O, the jaws on their inner sides engaging with the off-sets 71; force the lower ends e of the jaws apart so as to lit a nut of any size desired, the bolts j traveling in the slotways h.

When it is desired to reduce the opening between the jaws so as to fit a nut of small size, the operating piece D is forced downward, the jaws engaging with the inside of the inclined face of the shell, forcing them together.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A wrench, comprising a base, having flanges, a central recess having a washer therein, a shell adapted to be secured to the base and having slotways for the jaws, jaws adapted to travel therein, an operating piece, threaded, and engaging loosely with said jaws, and a shank threaded and adapted to operate said operating piece substantially as de scribed for the purposes set forth.

2. A wrench comprising a base having flanges, a shell adapted to be secured to the base, a central opening in the base, an operating rod in the opening, jaws adapted to travel in slotways of the shell an operating piece having lateral arms provided with slots and means for securing the jaws to the operating piece, and means for vertically adj usting the operating piece, substantially as described.

In witness whereof I have hereunto set my hand this 20th day of March, 1894.

JACOB G. BROWN.

In presence of- M. H. MURPHY, L. A. BAKER.
