JOHN E. SHELL, OF MONTICELLO, ARKANSAS.

WRENCH.

SPECIFICATION forming part of Letters Patent No. 465,542, dated December 22, 1891.

Application led October '7, 1891.

To @EZ whom t may concern.-

Be it known thatI, JOHN E. SHELL@ citizen of the United States, residing at Monticello, in the county of Drew and State of Arkansas, have invented a new and useful Wrench, of which the following is a specification.

This invention relates to improvements in wrenches; and the objects in view are'to provide a wrench adapted to serve as such and as a brace for holding in a secure manner various kinds of bits.

A further object of the invention is to provide a simple and convenient means for adjusting the jaws of the wrench, whereby the saine are adapted to release or grip a bit or be fitted to various sizes of nuts.

Other objects and advantages of the invention will appear in the following description, and the novel features thereof will be par ticularly pointed out in the claims.

Referring to the drawings, Figure l is an elevation of a wrench constructed in accordance with my invention. Fig. 2 is a vertical longitudinal section through a portion of the wrench-handle. Fig. 3 is a detail elevation of a bit adapted to be employed in connection with the wrench when the latter is used as a brace.

Like numerals indicate like parts in all the figures of the drawings.

1 denotes the rectangular stock or shank of the wrench, and at its extremity the saine ter minates in the usual transverse fixed jaw or head 2. The shank l is of crank shape-in other word s, is but one branch of an ordinary brace 3, which brace at its outer end has swiveled thereon the usual head 4e. etween its two branches the brace is cylindrical, and has loosely mounted for rotation and reci procation thereon a cylindrical sleeve 5, which at its inner end is adapted to bear against a shoulder 6, formed by the reduction of the brace, to form the cylindrical port ion thereof, and at its outer end a stop 5.

7 designates a sliding jaw mounted upon the rectangular portion l of the brace, and

'between the inner end of the jaw and t-he intermediate portion of the brace there is j ournaled, in suitable bearings formed in the jaw and brace, a screw-threaded rotatable feedrod 8, which near its inner end has formed 0r secured rigidly thereon a' toothed wheel or Serial No. 408,040. (No model.)

gear 9, the same entering a recess l0, formed in the stock or shank 1. The teeth of the gear 9 are engaged bythe teeth ll, formed at the outer end of the sleeve 5, so that any rotation upon the part of the `latter serves to communicate similar movement to the gear 9 and feed-rod S, and in this manner is the sliding head or jaw 7 made to reciprocate in either direction upon `the shank l. Vhen employed as a wrench, the sleeve 5 is first slid inwardly to engage the gear 9 and rotated in a proper direction to cause the movable jaw to fit over and clam'p upon the nut to be removed or applied, after which the sleeve is slid outwardly out of engagement with the gear 9, and the brace is handled in the usual manner and rotated so as to cause the wrench and nut to rotate either for the purpose of withdrawing or applying the latter.

l2 designates an ordinary bit-in this instance a screw-driver-adapted to be used in connection with the described brace, and said bit is provided with a fiat shank 13, adapted to rit between the opposingl j aws of the wrench,

and the end of the shank has formed therein a rectangular recess l5, adapted to receive and somewhat snugly fit that portion of the shank l between the two jaws, whereby it requires but a slight pressure of the jaws to maintain the bit in position and against any possible displacement. vWhen the brace is thus provided, it will be seen that it may be operated similar to any other bit. If desired, some such means as a spring-catch or thumb-screw may be provided to hold the sleeve out of engagement with the gear. The inner angle of the crank is thickened, as shown at l, so as to substantially agree with the diameter of the sleeve and in face form a continuation thereof. Vhen applying eXtra power, the hand of the operator may be slid from the handle over the enlarged portion l, and thus the power be more directlyapplied.

The face ot' the bit may be provided with a transverse rib 13, the same taking into a transverse groove 2., formed in the innerface of the jaw 7, and thus slipping of the bitwill be avoided.

Having described my invention, what I claim isM l. The combination, with the brace having one end squared to form a shank and termi- IOO nating in a xed jaw and at its opposite end in a swiveled head, of a sliding jaw mounted on the shank, a threaded feed-rod bearing in the sliding j aWand against the brace, a toothed wheel upon the rod, and a cylindrical sleeve mounted on the brace'and adapted to rotate and having its end toothed to engage the teeth of the Wheel, substantially as specified.

2. The bit having the tlat shank provided with a rectangular recess at one end, adapted to fit the shank of the Wrench, and provided with a transverse rib 13a, adapted to tit a lgroove in the jaw of the Wrench, substantially as speciied.

3. The combination, with the cranked brace v having one end squared to form a shank and terminating in a fixed jaw and at its opposite ends in a swiveled head, of a sliding jaw mounted on the shank, a threaded feed-'rod bearing in the sliding jaw and against the brace, a toothed wheel upon the rod, and a cylindrical sleeve mounted on the brace and adapted to rotate and reciprocate and having its end toothed to engage the teeth of the Wheel, substantially as specified.
