WRENCH. I

Specification of Letters Patent.

Patented. Dec. 25, 1906.

Application filed February 24, 1906. Serial No. 302,793.

Be it known that I, CHARLES LJBnooxs, a citizen of the United States, residing at Clearrnont, in the county of Sheridan and State of Wyoming, have invented certain new and useful Improvements in Wrenches, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to wrenches, and

more particularly to that class "of combined es embodying a nut-wrench and a pipe-wrench in one tool, the object being to provide a device of the character described that shall be simple and comparatively inexpensive in constructon, easy of manipula tion and operation, durable and efiective, and in which one of the jaws is fixed and the other slidably and adjustably mounted.

Other objects and advantages will be manifest from the following description, taken in connection with the accompanying drawings, which are made a part of this specification and in which like numerals designate corresponding parts.

In the drawings, Figure 1 is a erspective view of the complete wrench, an' Fig. 2 is a longitudinal section.

1 designates a shank having a fixed jaw memberZ formed integral with one end thereof, said fixed jaw member having alaterallyextending jaw 3 on one side thereof and on the other side a laterally-extending jaw 4, provided with teeth or serrations 5. The other end of the shank 1 is provided with a suitable handle 6, preferabl formed in two sections, which fit over the s ank and are re movably secured in lace thereon by means of the screws 7, which pass through openings 8 in the shank. Slidably mounted on the shank is the jaw member 9, which is provided with the laterally-extending jaws 10 and 11, the jaw 11 having a slightly-curved surface, as shown at 12, for the reception of pipesjof different diameters. Formed integral with this jaw member 9 is a sliding bar 13, provided with the notches or serrations 14, which are engaged by a pawl 1 5, which is suitably pivoted on a laterally-projecting lug 16, formed integral with the handle 6 and which passes through an oblong opening 17 in said pawl. The pawlis held in engagement with, the notches '14 by means of a coilsplring 18, interposed between the pawl and t e handle. I

In order that the sliding bar 14 may have room in which to be operated, the arts of the handle 6 are hollowed out to orm an open space, as shown at 19, for the reception of said bar.

The under side of the laterally-projecting lug-4, which is formed integral with the fixed jaw member 2 and which is provided with the notches 5, is suitably inclined, as shown, to engage pipes of different diameters.

- In operation the pawl disengages the notches in the sliding bar 14 when the other end is ressed down against the tension of the spring 18, so that the jaw member 9 may be adjusted to fit pipes of different diameters or nuts of different sizes, according to the wish of the operator.

It is thought that the construction and 0' eration of my invention is made clear by t e foregoing, taken in connection with the drawings, and further explanation is not deemed necessary.

Having thus described my said invention, whatI claim as new, and desire to secure by Letters Patent of the United States, is

The herein-described combined nut and pipe wrench comprising a shank having at one of its ends a transversely-extending integral head forming two stationary jaws, the inner face of one of the latter being inclined upwardly and outwardly and formed with serrations, a removable handle secured upon the reduced opposite end of said rectangular shank and composed of two half sections each being formed with opposing sockets to receive the end of the shank and with op osing sockets in communication with the 'rstmentioned sockets, one of said handle-sections being formed with an apertured integral lug projecting laterally from the up er end of said section and having a downwardly and inwardly inclined outer face, screwsinserted in transversely-alining apertures in said handle-sections and said shank for securing said parts together, a sliding head. mounted upon said shank and forming sliding j aws to coact with said stationary jaws, the upper face of one of said jaws being curved downwardly and outwardly to coact with the inclined serrated stationary jaw, an integral rack-bar projecting from said sliding head and in slidable contact with one edge of said.

shank, the lower end of said rack-bar being IIO central portion of said pawl bein formed with a longitudinal slot to receive t e lug on said handle-section and with transverse apertures in alinement with each other and the aprerture in said lug, a pivot-pin passed t ough said alining apertures in said lug and said pawl, and a coil-spring having its opposite ends arranged in seats formed in said handle-sections and the finger-piece of said pawl, substantially as shown and described. 10

In testimony whereof I hereunto afiix my signature in presence of two witnesses.
