THOMAS FOSTER WHITE, OF SALEM, KANSAS.

WRENCH.

SPECIFICATION forming part of Letters Patent No. 297,209, dated April 22, 1884.

Application filed September 8, 1883. (No model.)

To ILZZ wiz/0772, it 77u14/ concern:

Be it known that l', THOMAS F. WHi'TE, a citizen of the United States, residing. at Salem, in the county of Jewell and State of Kansas, have invented a new and useful Wrench, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to wrenches5and it has for its lobject to provide a device which will be readily convertible into a nut or pipe wrench at a moments notice.

To 'this end :it consists in certain details of construction and combination of parts, as hereinater set forth, and particularly pointed out in the claims.

In the accompanying drawings, Figure lis a perspective view of my device adj usted as a nut-wrench. Fig. 2 is a similar View when adjusted as a pipe-wrench, and Fig. 3 is a longitudinal section of Fig. 1.

The same lettersrefer to correspondingparts in the several figures.

For purposes of description, the end of the wrench farthest from the handle is the forward end, and the side on which the jaws are the front side.

Referring to the drawings, A designates the shank of an ordinary wrench, provided at the forward end with stationary jaw B and at the opposite end with a handle, C.

D designates the sliding jaw, provided with an opening, ci, for the passage of the shank, and having a rearward extension, E, to which is pivoted orjointed a forward extension, F, of a sliding sleeve, G, the latter sliding on the shank, and arranged to slide the jaw D toward or away from the stationary jaw. A ange, H, projects downwardly from the rear end of the sleeve G, and is formed with a groove, i, in its inner face, while a worm-wheel, I, longitudinally movable on the shank, engages with the groove in the iiangc, so as to cause the longitudinal movement of the sliding jaw carrying the sleeve. The circumference of the lworm-wheel is provided with serrations or with a milled edge, in order to provide for the ready manipulation of said wheel. It will be seen that the extension F of the sleeve is bifurcatcd or slotted to receive extension E of 5o the sliding jaw, said extension E readily tting within and working in the slot, so that the conversion from a nut to a pipe wrench can be easily performed. A. spring, J, is secured to the front or upper face of shank A, andbears against the inner face ofthe sliding jaw, so as to press said jaw outward when working on pipe or round iron, and apointed screw or rod, K, works through au opening, Z, in the side of the slidingjaw, so as to engage with a longitudinal groove, L, formed on the side of shank A. This pointed screw or rod guides the sliding jaw when used as a nutwrench, and also serves as a means for adj ustment of the wrench from a wrench for nuts to a wrench for working on pipes or round iron. The inner faces of the jaws D B are serrated, milled, or provided with teeth to engage with the pipe or nuts in turning, said teeth or serrations extending bin opposite directions on each jaw.

The operation of my invention'can be readily understood from the foregoing description, taken in connection with the annexed drawings.

When used as a nut-wrench, the screw Kis engaged with grooveL and guides the sliding jaw and sleeve in its movements, the manipulation of worm-wheel I causing the sleeve to slide upon the shank, the said sleeve, by means of :its connection with the sliding jaw, causing the latter to move longitudinally on the shank. Thus the turning of the worm-wheel regulate the distance between the jaws B D.

To change the nut wrench into a pipewrench, the screw or rod K is first withdrawn from slot L, and 'since the lower or sliding jaw is jointed to the extension of the sleeve, and is, furthermore, forced toward the front side of the wrench by spring J, said sliding jaw will be thrown to the position shown in Fig. 2, and can thenbe used to turn pipes or round iron in making joints or like work.

When used as apipe-wrench, the operation IOO to mechanics, since heretofore two different wrenches have been used to perform the functions-of my single device. I thereby avoid the cost of the other wrench, while the great convenience arising from its use will be appreciated by all.

. It is apparent that numerous modifications can be resorted to in the foregoing without de parting from the spirit or scope of my invention.

Having described my invention, I claim as newl. In a wrench, the shank provided with a slot or groove in its side, in combination with the sliding jaw pivoted or jointed to a sliding sleeve, and a pointed screw or rod working through the side of the jaw and engaging with the slot or groove, as and for the purpose set forth.

2. In a wrench, the shank A, carrying stationary jaw B, and provided with a longitudinal groove in its side, in combination with the sliding jaw pivoted or jointed to a sliding sleeve, and having a pointed screw or rod en` gaging with the longitudinal groove, and a spring secured to the shank and bearing against the inner face of the sliding jaw, substantially as and for the purpose set forth.

3. In a wrench, the shank A. provided with a longitudinal groove or slot in its side, in combination with the sliding jaw formed with a rearward extension, a sleeve provided with a forward extension, which is pivoted or jointed to the said rearward extension, a pointed screw or rod working through the sliding jaw and engaging with the groove in the shank, and a spring bearing against the inner face of the sliding jaw, as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in 4o presence of two witnesses.
