This invention relates to an improvement in wrenches, either monkey wrenches or pipe wrenches, the object of the invention being a simple construction of parts, and giving a maximum amount of strength; and the invention consists in the construction hereinafter described and particularly recited in the claim.
In carrying out my invention I form the fixed or upper jaw 2 integral with the shank 3 and handle 4:, and preferably from a single piece of cast steel. The shank portion 3 is rectangular in cross-section. Atthe lower end of the shank I form two outwardly projecting integral fingers 5, 6, and above the fingers is a notch 7 and below the fingers a notch '8. The upper jaw 2 may have a flat inner face, as shown in Fig. 1, for use as a nut wrench, or the fixed jaw 2 may have a toothed face 9, as shown in Fig. 3 of the drawings, adapting the wrench for a pipe wrench. The movable jaw 10 is provided with an extension 11 having a vertically arranged threaded opening to receive a screw 12 formed at its lower end with two circular retaining and operating flanges 13 and 14 Specification of Letters Patent.

adapted to be placed one above the fingers 5 and 6 and one below them, and the ends of the fingers are bowed around the portion 15 of the screw between the flanges 13 and 14 so that the screw is swiveled to the shank. The movable jaw 10 is held in proper relation to the shank 3 by a sheet-metal strap 16 which is folded around the shank 3 and secured to the opposite sides of the extension 11. The wrench is operated in the usual manner by turning the screw by means of the flanges 13 and 14, and this turning of the screw moves the jaw 10 toward or from the fixed jaw 2.
This construction, as will be seen, is extremely simple to manufacture, and the parts readily assembled, and when assembled forms a strong tool.
I claim In a wrench, the combination with a shank formed at one end with an integral jaw, at its opposite end with an integral handle, and upon its inner edge close to the inner end of its handle with two parallel integral fingers extending at right angle to the line of the said shank and handle; of a movable jaw having a downward extension formed with a threaded opening, an operating-screw en tering the said threaded opening and formed at its lower end with two circular retaining and operating flanges separated from each other by a space slightly wider than the width of the said fingers which are extended into the said space and clasped around that portion of the screw between the two flanges for retaining the screw in place. and a sheetmetal strap embracing and riding upon the said shank and secured to the said extension of the movable jaw which it retains in place and guides.
In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
