UNITED STATES PATENT OFFICE.

HENRY J. BALLEM, OF WINTER/OP, MASSACHUSETTS, ASSIGNOR TO HIMSELF, AND WILLIAM J. QUIRK, 0F QUINCY, MASSACHUSETTS.

PIPE-WRENCH.

Specification of Letters Patent.

Patented J une 9, 1914.

To all whom it may concern Be it known that I, I-IENRY J. BALLEM, a citizen of the United States, and a resident of Winthrop, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Piperenches, of which the following is a specification.

My invention relates to pipe-wrenches and its objects are to improve the construction of such wrenches in the manner hereinafter set forth and to provide an attachment whereby the wrench may be employed as a pipe-cutter.

My invention will be described by reference to the drawings which accompany and form a part of this specification; but it will be understood that various modifications may be made in the particular construction illustrated without departing from the spirit of my invention.

In the drawings, Figure 1 is a side view of my improved wrench, showing the position of the parts when the device is used as a pipe-cutter. Fig. 2 is a plan view and Fig. 3 is a side view showing the position of the parts when the device is used as a wrench.

In the particular drawings selected for more fully disclosing my invention, 1 represents the outer jaw of a pipe-wrench having the usual serrated inner face and cast integral with the rectangular shank 2. The inner jaw 3 having a similar serrated face, is provided with a socket 4 to receive the shank 2, said socket being large enough to permit of relative motion in the plane of the jaw between said jaw and shank, and is connected with the threaded stock 5 by means of the pin 8 passing horizontally through the jaw and cooperating with the groove 6 milled into the extension 7 of said stock, so that the latter is capable of rotary, but not longitudinal, motion with respect to the aw 3 whereby the rotation of said handle will move the inner jaw with respect to the outer.

The band 9, which is in threaded engagement with said stock is provided with asocket 10 for receiving the shank 2, and a pin 11 holds the latter in pivotal engagement with said band, said socket, as shown, being large enough to permit of a certain amount of play between the stock and band. A spring 12 is provided to normally hold the inner jaw away from the shank 2, and in the present instance one end of said spring is secured to the upper wall of the socket 4 and the other end is in engagement with the shank. It willbe obvious that any suitable means may be employed for providing for relative motion between the inner jaw and the shank and also for normally holding the former away from the latter.

By means of the handle 20, preferably integral with the screw-threaded stock, the

inner jaw may be adjusted against the pipe or other cylindrical member to be rotated.

In order to adapt the wrench to use as a pipe-cutter, I pivotally connect to one of the jaws a shield 14 and to the other a cutterblock 17, having a rotary cutter 18 mounted therein by means of the pin 18. In the present instance the shield 14 is shown pivoted to the outer end of the outer jaw by means of the link 13 and the cutter-block is shown as pivoted to the outer end of the inner jaw by means of the links 16, 16, although it will be understood of course that if links are employed for pivotally attaching the shield and cutter-block to their respective jaws, a single link may be used to connect the cutter-block and the inner jaw and a double link to connect the shield to the outer jaw. It will also be obvious that the relative positions of the shield and cutter-block may be reversed and that if desired, a cutter-block identical with that shown at 17 may be substituted for the shield 14. When the device is being used as a wrench, the shield and cutter-block are turned back as shown in Fig. 3, and in such case, if desirable, they may be held intheir inoperative respective positions by the spring-catch 15, which snaps over the end of the shield and the spring-catch 19 which snaps over a projection on the cutter-block, such for example, as the end of the pin 18', the cutter 18, when the cutter-block is in its inoperative position fitting into the recess 3 in the inner jaw 3.

When the wrench is used as a pipe-cutter, it is desirable to provide a hand-grip to furnish the necessary leverage for turning the handle and threaded stock to force the cutter into the pipe prior to rotating the device around the pipe. For this purpose I provide a member 21 arranged to be received in the pocket 22 of the handle and held therein by the spring-catch 23 which engages one end thereof, the other end being bent as shown at 24 and shaped to pass through the hole 25 and fit snugly against the inner wall of the opposite pocket 22.

When in use as a grip, the rod 21 is passed through the hole 25 so as to lie in a plane transverse to the longitudinal axis of the handle as shown in Fig. 2.

In order to extend the length of the handle, the threaded end 27 of the hand-grip may be screwed into the threaded end 26 of the handle.

I claim:

1. A wrench having jaws, each provided with a, serrated inner face, a shield, a link pivotally connecting said shield to the outer end of one jaw, a cutter-block, a link pivotally connecting said cutter-block to the outer end of the other jaw, said cutter-block being provided with a groove, and a cutter pivoted to said cutter-block and partially V inclosed within said groove, the jaw to which said cutter-block is pivoted being provided wit-ha cooperating recess for housing Gopies'of this'patent may be obtained for said cutter when said cutter-block is in its inoperative position.

2. A wrench having jaws, each )rovided with a serrated inner face, a shiel a link pivotally connecting said shield to the outer end of one jaw, a cutter-block, a link pivotally connecting said cutter block to the outer end of the other jaw, and a cutter pivoted to said cutter-block, the jaw to which said cutter-block is pivoted being provided with a recess for housing said cutter when said cutter-block is in its inoperative position.

In testimony whereof, I have hereunto subscribed my name this 20th day of September, 1913.

HENRY J. BALLEM. Witnesses GEO. K. ooowon'rn, E. B. ToMLINsoN.
