UNITED STATES PATENT OFFICE.
RANDOLPH HAYDEN, OF MIDDLETOWN, CONNECTICUT.
WRENCH.
SPECIFICATION forming part of Letters Patent No. 228,755, dated June 15, 1880.
Application filed March 16, 1880.
To allwhom it may concern Be it known that I, RANDOLPH HAYDEN, of Middletown, in the county of Middlesex and State of Connecticut, have invented certain new and useful Improvements in Wrenches and I do hereby declare that the following is a full, clear, and exact description thereof, whereby a person skilled in the art can make and use the same,- reference being had to the accompanying drawings, and to the letters of reference marked thereon.
Like letters in the figures indicate the same parts.
My invention relates to wrenches which have a sliding adjustable jaw, and are commonly called monkey-wrenches.
The object of my invention is to provide a wrench of the kind above named which shall be simpler and cheaper in its construction than those heretofore manufactured, and at the same time be an efficient and useful tool.
In the accompanying drawings, Figure 1 is a side view of my improved wrench with the top plate of the handle removed to show the interior parts and the method of attaching the top plate. Fig. 2 is a View of the under side of the top plate. Fig. 3 is a cross-section of the complete wrench upon the line a b, Fig. 1. Fig. 4 is a cross-section of the complete wrench upon the line 0 d, Fig. l;
A is the chief part of the handle, which contains the working parts. B is a coveringplate, which is secured upon the part A to hold all the parts in place. 0 is a rectangular bar, which slides and fits in a rectangular pocket in the part A, and carries the movable jaw D upon its outer end. The corresponding fixed jaw E forms part of A.
(ModeL) Upon the rear end of the bar 0 is cut the screw-thread G, which, when the jaws are closed, enters a receptacle, A, in the rear end of the part A.
G is a milled nut turning upon the screw 0 and resting in a socket in the handle, so that its sides project, as shown in Fig. 3, and permit it to be operated in the usual manner to open or close the jaws.
The openings in the sides of the parts A and B are made smaller than the diameter of the nut, so that it cannot fall out when the bar 0 is wholly unscrewed and withdrawn from the handle. It is placed in its socket before the parts are put together, and is afterward securely held in place.
H H are studs or projections cast upon the part A, adapted to enter into corresponding holes I I in the part B, and be riveted down to secure the two parts together. If the part A be made of malleable metal the projections H may form a part of it, or they may be pieces of wire cast into it in any ordinary manner.
The parts 0, D, and G can be made of cast or malleable metal in any customary manner,
and are placed in the handle before it is riveted together. The bar 0 can, however, be inserted afterward, if desired.
What I claim as my invention is- The combination of the part A, provided with the jaw E, the part B, the bar 0, )ro' vided with the jaw D and a screw-thread, O, and the nut Gr, all constructed and arranged substantially as described.
- RANDOLPH HAYDEN.
