WRENCH.
SPECIFIGATION forming part of Letters Patent No. 289,069, dated November 27, 1883.
Application filed October 17, 1883. (No modclfl To all whom it may concern;-
Be it known that I, JOHN H. Cons, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in renches; and I declare the following to be a description of my said invention sufficiently full, clear, and exact to enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this'specification.
This invention relates to that class of screwwrenches known as the Goes Wrench, and in which the sliding jaw is adjusted by means of a rosette and screw located in front of the bar, with the rosette pivoted on a projecting portion of the handle-ferrule, and the top end of the screw entering the cylindrical portion of the sliding jaw.
The objects of my invention are to provide a more efiicient support for the jaw upon the screw than the ordinary loosely-fitting threads formed in the lower part of the j aw,t0 obviate the liability of the threaded portion of the j aw, which is of malleable iron, from becoming worn out and from slipping on the screw, and to aiford an independent close fitting threaded portion or case-hardened nut for sustaining the strain on the screw, while allowing sufficient looseness of the jaw to give the necessary freedom of action thereof on the bar. These objects I attain by the mechanism shown in the drawings and herein described. The particular features claimed are hereinafter definitely specified.
In the drawings, Figure 1 is a side view of a Goes wrench illustrating my invention. Fig. 2 is a central section of the jaw and sustaining-nut separate from the bar. Fig; 3 is a central section of the sustaining-nut alone. Fig. i is a bottom view of said nut and jaw, and Figr5 is a'oentra-l section of the jaw alone.
In the construction of my improved wrench the bar A, handle 13, and rosette-screw C may be of the ordinary well-known form heretofore employed in the Goes wrench.
part of the cylindrical portion, into which the screw G enters, the jaw being provided with an internal screw-thread, 1d, above the said recess, as illustrated.
A nut or sustaining-piece, F, is arranged upon the screw 0, below the jaw D, and fitted into the angle of the recess E,against the base of the jaw. The back of said nut is made straight and flat, as at f, to rest squarely against the front of the bar A and prevent the nut from rotating with the rotation of the screw 0, or against the bar and the sides '6 c of the lower baud, h, on the jaw D. Thefront of the nut F is made to correspond with the form of the lower part of the jaw-front, so as to give a smooth and uniform finish therewith. The screw-thread d of thenutF is made to fit closely upon the thread a of the screw 0, and is so made as to be continuous with the thread 61 inthe jaw D, or so that the screw will follow accurately from one part to the other, without deviation, when the top of the nut is resting against the metal of the j aw. The thread (11 in the jaw is made to fit the screw quite loosely, so that the jaw can have the necessary freedom of action on the bar A. The nut F is case-hardened, or may be of hardened steel, so that its thread will not wear out readily. IV hen in use, the close-fitting threads d of the hardened nut F sustain the strain or backward thrust of the jaw when at work, while the amount of adjustment than wouldbe the case if the nut were wholly below the jaw.
What I claim as of my invention, and desire to secure by Letters Patent, is
1. The combination, with the sliding jaw 9 and rosette-screw in a Goes wrench, of a casehardened nut adapted for sustaining said jaw, and having a screw-thread formed continuous with the screw-thread within said jaw, substantially as set forth.
combination with the headed barA andhandie 10 B, as set forth.
Witness my hand this 13th day of October,
2. The nut Rhaving thread (1 fitting closely on the thread of the screw 0, in combination with the jaw AD, having thread d fitting loosely upon the thread of said screw for the purpose I A. D. 1883. 5 set forth. JOHN H GOES 3. The jaw D, having the recess E, the inde- V pendent nut F, fitting within said recess, and Witnesses:
the screw 0, engaging'with screw-threads in OHAs. H. BU LEIGH, both said parts as shown and described, in
