wrench complete.
The body of the wrench A A is composed of two parts, pivoted together at 0. An adjusting thumb-screw, B, passes through A below the pivot O, and has a bearing against the part of the body A. The wrench is furnished with two plain jaws, N N, a handle, D, projecting thumbpiece D, and socketjaws E E. The plain jaws N N are used for common nuts in the same manner as a fiat wrench, the jaws being adjusted to nuts of different sizes by means of the thumb-screwB. Thesejaws may also be used as a hand-vise, as articles may be held very tightly between them by the force of the set-screw. Projecting from the-body of the wrench are the two socket-jaws E E. These are made to project far enough from the body of the wrench to be used upon the nuts jaws to nuts of diflerent sizes, but also for tightly clamping nuts of various shapes, to
hold them firmly while being turned upon thescrew.
What I claim as my invention, and desire to secure by Letters Patent, is
The pivoted adjustable wrench, having jaws N N and E E, provided with handle, combined with back-handed lever and fingernece D and pressure set-screw, substantially as specified. I
