PIPE-WRENCH.

SPECIFICATION forming part of Letters Patent No. 701,237, dated May 27, 1902. Application filed November 18,1901. Serial No. 82,663. (No model.) a

To ctZZ 1071,0122, it may conccrlu Be it known that I, ORSONQT. WIGHT, a' citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Pipe-Wrenches; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to and its object is to provide a pipe-wrench having but one arm, lever, or handle and which will automatically and instantly firmly engage a pipe or other cylindrical object by merely pressing the handle or lever endwise against the object to be clamped. 'I attain these objects by means of the devices and arrangement of parts hereinafter described and shown, and illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of my wrench with the jaws closed; Fig. 2, a side elevation of the same with the jaws wide open. In this View one of the side walls of the jaw 6, hereinafter referred to, is removed for the sake of clearness. Fig. 3 is a side elevation of my device with the jaws gripped upon a pipe.

Like numerals of reference indicate like parts throughout the drawings.

In the drawings, 1 isa lever or handle. In small wrenches this handle may be made of malleable iron. to employ a forging. At one end this handle is bifurcated, having forks 2 and 3. Through the fork 2 near its end passes transversely a pin 4, the ends of whichproject slightly beyond the forks sides. Through the other fork 3 near its end passes a like pin 5. 6 and 7 are a pair of pipe-jaws hinged together, as at S, by means of pin 9. The adjacent faces of these two jaws are curved, so that when the jaws are closed the opening forms approximately a circle. The jaw 7 is recessed along its back, as at 10, (see Fig. 1,) to receive the fork 3. The projecting ends of the pin 5 pass through the side walls of the recess 10 and form a pivot, upon which the jaw 7 swings. The back of the jaw 6 is also recessed, as at In large wrenches I prefer- V 11, toreceive the fork 2. This recess has in each of its side wallsa curved channel or groove 12, which receives the projecting ends of the pin l. The pin and groove forma guide and support upon which the jaw 6 may slide to andfro.

Across the inner face of the jaw 7 is a slot of such shape in transverse section that when a square die 13 is driven lengthwise into the slot one of the square corners of the die will project inwardly slightly beyond the inner curved face of the jaw. When the jaws are in engagement with a pipe, this projecting V corner of the die will engage the surface of the pipe and will prevent the jaws from slipping.- When the corner of the die becomes dulled, the die may be removed and be given a part turn and returned to place. A sharp corner will now be exposed, and thus all four of the corners of the die may be utilized.

The operation of my device is as follows: The handle being held in both hands of the operator, a longitudinal forward jerk of the handle will throw the jaws wide open, as shown in Fig. 2. If the hinged part of the jaws be now pushed against a pipe, the jaws will swing upon their hinge and upon their pivots 4 and 5, the jaw 6 will slide backwardly upon the ends of the pin 4, the two jaws will assume the position illustrated in Figs. 1 and 3, and the pipe will be clasped between the inner curved surfaces of the two jaws. If the handle be now swung in the direction of the jaw 6, the pin 4, sliding in its curved channels 11, will force the jaw 6 inwardly against the pipe, and the jaw 6, through its hinged connection with the jaw 7, will pull the latter jaw into close contact with the pipe. The stronger the lateral pressure upon the handle 0 the tighter will be the grip of the two jaws. WVhenthe handle is swung in the opposite direction, the pin ,4, sliding in the curved grooves 11, will cause the reverse operation to take place,and both jaws will at once spread 5 apart and release the wrench. Toturn the pipe in the opposite direction, itis only necessary to give the wrench a half-turn, so that the two jaws will exchange positions.

Having described my invention, what I ma claim as my invention, and desire to secure by Letters Patent, is

sliding connection between the other fork and the other jaw, and a. removable tooth in the gripping-face of one of the jaws.

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

ORSON J. WIGHT.
