PIPE WRENCH AND CUTTR.v

SPECIFICATION forming part of Letters Patent N o. 630,925, dated August 15, 1899.

Application filed January 3, 1899. Serial No. 700,879. (No model.)

To all whom, it may concern:

Beit known that I, PETER H. POPPERT, a citizen of the United States of America, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in a Combined Pipe-Wrench and PipeCutter; 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 improvements in a combined pipe-wrench and pipe-cutter, my object being to provide a device of this class which shall be simple in construction, economicalin cost, reliable, durable,and efficient in use; and to these ends the invention consists of the features, arrangements, and combinations hereinafter described and claimed, all of which will be fully understood by reference to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure l is a side elevation of my improved device, the reversible jaw being arranged for pipe-cutting. Fig. 2 is a front edge view of the same. Fig. 3 is a side elevation of the tool, shown on a larger scale, the handle being broken away. In this View the reversible j aw is arranged for wrench purposes.

Similar reference characters indicating corresponding parts in these views, let the numeral 5 designate the shank of the tool, which is secured to the housing 6 by rivets 4. rlhrough the upper part of the housing 9, above the shank, is passed the threaded portion 7 t of the jaw 7. This part 7 u also passes through a nut 8, provided With Spanner-openings S. The housing 6 is cut away to let in this nut and permit it to rotate.

Supported by the housing and located in the rear of the jaw 7 is the jaw 9, provided with a rotary cutter 9a at one extremity, its opposite extremity being toothed, as shown at 9d. This jaw 9 is provided with a slot 9c (shown in dotted lines) and is supported in the housing by a pin l0, which passes through the slot 9c and is fast in the housing.

The jaw 9 is adapted to slide and turn on this pin, wherebyits position may be reversed to adapt it for pipe-cutting or wrench purposes, as may be desired. The rear eXtremity of this jaw is supported on one side by a shoulder 5, formed on the forward extremity of the shank 5, which projects into the housing and is shown in dotted lines. The opposite side of the reversible jaw is engaged by a pin l2, fast in the housing. WhenA the tool is in use, the pinlO engages the forward extremity of the slot 9C. This pin prevents the jaw from moving backwardly during use. When it is desired to reverse the jaw or change its position from that shown in- Figs. l and 2 to that shown in Fig. 3, the jaw 9 is first moved forward until the pin lO engages the opposite or rear extremity of the slot 9c. The jaw may then be reversed by turning it on the pin lO in the direction indicated by the arrows in Fig. l. The lower part of the housing, as well as the shoulder 5a of the shank, is provided with a V-shaped recess, which the rotary cut-ter enters during the operation of reversing the position of the jaw. The tool is so constructed that the cutter end of the jaw 9 always moves down and the toothed end up when beginning the turning movement. Hence in changing the jaw from the position shown in Fig. 3 to that shown in Figs. 1 and 2 the jaw would be turned as indicated by the arrows in Fig. 3. The reason for this is that the distance is farther from the outer edge of the rotary cutter to the center of the pin l0 when the jaw is in the position shown in Figs. l and 2 than from the toothed edge of thejaw to the center of the same pin when the jaw is in the position shown in Fig. 3, and the construction is therefore such that more turning room is allowed the cutter end than the toothed end of the jaw.

When using the tool, the jaw 7 may be tightened upon the pipe, which is engaged on the opposite side, by either the rotary cutter or the toothed end of the reversible jaw. In tightening the jaw 7 a Spanner, which engages the openings 8a and the nut 8, may be 2 eopae employed. In cutting the pipe after the jaw 7 has been properly adjusted the tool is simply turned around the pipe until it is properly out.

Having thus described my invention, what I Claim isl. The Combination with a suitable supporting frame or honsing-i and an adjustable jaw mounted thereon, of a coperating reversible jaW, also mounted on the frame, and arranged to turn in the plane of the adjustable jaw, whereby either extremity may be made to coperate with the adjustable jaw as circumstances may require.

2. The combination with a suitable supporting frame or housing and an adjustable jaw mounted thereon, of a cooperating reverL sible jaw, 'also mounted on the frame, said jaw having a slot formed therein, and a pin fast on the frame and passing through the slot of the jaw, which is arranged to turn thereon, whereby either extremity mayl be made to ooperate with the adjustable jaw as circumstances may require.

In testimony whereof I aix my signature in presence of tWo Witnesses.
