COMBINED PIPE WRENCH AND CUTTER.

SPECIFICATION forming part of Letters Patent No. 514,000, dated February 6, 1894.

Application filed November 28, 1893. Serial No. 492,277. (No model.)

To aZZ whom t may concern.-

Be it known that I, JOHN GREEN, a citizen of the United States, residin g at Renovo, in the' V and has especial reference to that class of wrenches used by steam and gas-fitters and generally designated as pipe wrenches, and has for its object certain improvements in construction whereby a right and lefthand wrench is produced, and one in which a variety of sizes of pipe can be manipulated with the minimum of motion of the parts and a ready and convenient pipe cutter produced.

The invention will be fully disclosed in the following specification and claims.

In the accompanying drawings which form part of this specification, Figure l represents a side elevation; Fig. 2 a like view with the head of the wrench in vertical section; Fig. 3 an end View; Fig. 4t a vertical section of the head of the wrench showing a modification in the construction; Fig. 5 a plan of one side of the movable jaw showing right inclined teeth and Fig. 6 a like view of the opposite side of said jaw showing left inclined teeth.

Reference being had to the drawings and the letters thereon, A indicates the lever portion of the wrench and B the head. On the head are two fixed jaws o, b and a curved inner surface c. The jaw h is in a plane coincident or parallel with the longitudinal center of the lever A, and in the outer end thereof is a slot d forming lugs or ears e e between which is pivotally secured a movable jaw C which is provided with right inclined teeth or serrations f on one side and with left inclined teeth or serrations g on the opposite side, the teeth f being ,designed to grasp a pipe or nut between them and the inner surface of the jaw a to turn a pipe or nut to the right, and the teeth g to grasp a pipe or nut between them and the inner surface of the jaw h to turn the pipe or nut to the left. The jaw C is adjusted by a screw D which may engage the threaded lug h as shown in Figs. l'and 2, or the arm or extension c' of thejaw C may be threaded and the screw engage therewith as shown in Fig. 4. The screw D passes through a slot la in the arme' or in the lug h as the case maybe, and is manipulated by a head Z on the end of the screw, and which is preferably spherical and provided with holes m for the reception of a pin to turn the screw and adjust the movable jaw C. On the opposite side of the arm c' is a nut n also preferahly spherical and provided with holesl o, between which head Z and nut n the arm c is held securely and moves with the screw when the thread is in the lug h, or they engage two sides of the lug 71, when the thread is in the arm c'. The arm t' may be provided with an additional hole q to adjust the movable jaw for use on larger pipe either for screwing them together or for cutting the pipe.

In the movable jaw C is a detachable cutter jaw h of the wrench, and the feed of the cutter regulated by the screw D as in the adjustment of the jaw C for pipe of diierent diameters, the slot lo allowing the jaw and the arm to assume different angles.

By the construction shown, the wrench may be made to accommodate pipe or nuts of different diameters, the large pipe being engaged bythe stationary jaw a and the movable jaw C, and the small pipe being engaged by the jaw h and the jaw C. The jaw C may also be adjusted to bring it in a plane coincident or parallel with the jaw a for use upon bolt heads or nuts of the greatest cross sectional area the wrench is capable of grasping, and smaller nuts may be grasped when the jaw C is at an angle to the jaw a. The pipe cutter lo may be readily inserted in the slot r in the jaw C and secured by a bolt s and nut t when the cutter is required, and as readily removed after the work of cutting pipe has been ac complished so that the cutter will not interfere with the effectiveness of the wrench.

Having thus fully described my invention, what I claim is- 1. A wrench provided with two fixed jaws, and a movable jaw pivotally connected to the IOO outer end of one of the fixed jaws and extending between said jaws, in combination with means for adjusting the movable jaw.

2. A wrench provided with two fixed jaws, a movable jaw pivotally connected to the outer end of one of the fixed jaws, and a lug in combination with an adjusting screw engaging the arm of the movable jaw and the lug.

3. A wrench provided with two iixed jaws, a movable jaw pivotallj7 connected to the outer end of one of the fixed jaws and laterally movable therein, in combination with an adjusting screw.

4. A wrench provided with two iixed jaws,

and a movable jaw pivotally connected to the presence of two Witnesses.

JOI-IN GREEN.
