WRENCH.
No. 445,356. Patented Jan. 27, 1891.
NITE all TATES JOHN B. PERAULT, OF BELMONT, MASSACHUSETTS.
WRENCH.
SPECIFICATION forming part of Letters Patent No. 445,356, dated January 27,1891.
Application filed November 10, 1890- Serial No. 3701854- (No model.)
To all whom it may concern.-
Be it known that I, JOHN B. PERAULT, of Belmont, in the county of Middlesex, State of Massachusetts, have invented certain new and useful Improvements in renches, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this speci fication, in which- Figure 1 is a top plan view of my improved wrench; Fig. 2, a side elevation of the same, and Fig. 3 an end elevation.
Like letters of reference indicate corresponding parts in the different figures of the drawings.
My invention relates to nut-wrenches provided with adjustable jaws and which are especially adapted for use with a bit-stock; and it consists in certain novel features hereinafter fully set forth and claimed, the object being to produce a simpler, cheaper, and more effective device of this character than is now in ordinary use.
The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation.
In the drawings, A represents the body of the wrench, which is provided with a beveled rectangular head 1), adapted to be inserted'in the stock in the ordinary manner of bits.
B 0 represent the jaws of the wrench, said jaws being respectively pivoted at (Z in the body A and adapted to swing or open laterally therein. The opposite ends of the jaws are chambered or soeketed longitudinally at g, forming a rectangular opening (best shown in Fig. 3) when said jaws are closed. Abolt 71. passes through the jaws B O, and a thumbnutz' is turned onto one end of said bolt, whereby the play of the jaws may be regulated. The wallsj of the jaw-openings 9 diverge inwardly to receive the nut D and engage the sides thereof when open, as in Fig. A V-shaped spring m, secured in the body A, spreads the jaws B C.
In the use of my improvement the body A is secured in the bit-stock in the ordinary manner, and the jaws B C adjusted by means of the bolt and nut, so that the chamber will receive said nut, when by rotating the stock in the ordinary way the nut may be turned on or off.
The walls of the chamber g may be shaped to conform to hexagonal or octagonal nuts,or such nuts may be manipulated with the root angular opening, if desired.
Having thus explained my invention, what I claim is 1. A nut-wrench comprising a body adapted to be secured in a bit-stock, two parallel jaws pivoted to swing laterally in said body and chambered to receive a nut, and mechanism for setting the jaws against said nut, substantially as described.
2. In a nut-Wrench, a body combined with two parallel jaws pivoted to spread therein and having their free ends recessed to receive a nut, a spreading-spring in the jaws, and a bolt and nut for adjusting said jaws, substantially as described.
3. In a nut-wrench, the body provided with a-bit-head, in combination with jaws B O, pivoted in said body and provided with recesses g, having diverging wall j, and mechanism for adjusting said jaws, substantially as described.
4. In a nut-wrench, the body A, provided with the head I), in combination with the pivoted jaws B C, recessed at g and having the inclined walls j, the spring m, the bolt 72, and
nut tfOl' adjusting said jaws, substantially as described.
