PEISEOH BLUM, OF NEW YORK, N. Y.

HAND PIPE CUTTER, THREADER, AND WRENCH.

To all whom it may concern:

Be it known that I, PEISECH BLUM, a citizen of the United States, residing at 1697 Lexington avenue, New York, county of New York, and State of New York, have invented certain new and useful Improvements in Hand Pipe Cutters, Threaders, and W'renches, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The object of this invention is to furnish a pipe fitters or gas fitters hand-tool with a pipe-cutter and with a pipe-threading die, so that the same tool may be used to cut off lengths of pipe and to form threads upon their ends.

The tool is of the class having two handlevers jointed together, and the cutter in the present invention is journaled in the end of an arm which is pivoted upon one of the levers, and is connected by a link to the other lever so that the pressing of the levers, together forces the cutter toward the pivot of the levers. One of the levers is termed here in the main lever, upon which the actuating. lever and the cutter-arm are pivoted at a suitable distance apart, and the actuating lever is provided with a jaw or seat upon which the pipe is supported during the operation of the cutter. Rolls are j ournaled upon the actuating lever in suitable positions to support pipes of different diameters when the cutter is in operation.

A die-holder is provided for the threadingdie,- having guides for the die to hold the same between the two hand-levers, the holder having lugs to embrace the outer side of the levers to hold them closed, and the holder having buttons or other means of locking the holder upon the levers, when the die and holder are in use. The threading die-holder is secured in a fixed position upon the levers by a pin in the holder engaging a hole in one of the levers. The cutter-arm is so pivoted that the cutter crowds normally into the pipe when rotated around the same for cutting it off.

The invention will be understood by reference to the annexed drawing, in which Figure 1 is a side elevation of the tool with the levers closed and the threading dieholder clamped thereon; Fig. 2 is a plan of the threading die-holder; Fig. 3 shows the inner side of the same opposite to that shown in Fig. 1 Fig. 4 is an edge view of the threading die-holder; Fig. 5 is a front view of the Specification of Letters Patent.

the levers separated to operate upon a relatively large pipe; Fig. 8 is an edge view of the tool which is represented with the levers separated, as in Fig. 7, but the holder shown at the side of one of the levers as it would appear when in its operative connection therewith.

a designates the mainlever having apivot b The main lever is extended beyond the pivot 12, with a lateral curve d, to a pivot d upon which the cutterarm 6 is jointed and carries the cutter 1f journaled upon its end. The actuating ever 0 has an extension 0, the free end of which is provided with a pipe bearing roll e. The pivots g of this roll and of the cutter f are coupled by links g. Adjacent to the pivot 12, the actuating lever is provided with a jaw i which is curved upwardly toward the cutter, and serves as a seat to support the pipe 0 or 0 during the cutting operation. A groove f is formed in the jaw to admit and clear the bur which forms upon the exterior of the pipe when penetrated by the cutter.

A roll 77. is journaled upon the jaw adjacent to the pivot 12, and operates to sustain small pipes like the pipe 0 shown in Fig. 1, during the cutting operation, while the roll h operates to sustain larger pipes, like the pipe 0 shown-in Fig. 7.

The main lever a is provided beyond the pivot d with a pipe wrench jaw j, and the cutter-arm e is provided beyond the same pivot with a similar opposed wrench jaw 7c.

The movement of the levers or handles a, c, operates to open and close these wrench jaws, as well as to move the cutter f to and from the seat or jaw 'i, and the levers thus serve a double function.

To facilitate the manufacture, the main arm a is formed with a recess a in one side extending past the pivots b and d, to receiving the actuating arm 0; and to centralize all the strains upon the cutter and pipe sup porting rolls, the cutter-arm is forked, as shown in Fig. 8, and the pivot extended through the cutter has the links secured upon both its opposite ends. In like manner, the free end or extension 0 of the actuating arm is forked to carry the roll 6, and the pivot of such roll is in like manner extended beyond the sides of such end to receive the links 9.

The ears upon the base of the jaw 01 which carry the roll n also from a fork to receive the roll, so that the rolls and cutter lie upon the center line or the levers.

To support the pivots b and d upon the outer side of the recess a, a re-inforcing plate 2 is applied to the face of the main lever over the recess, and secured to the lever at both ends by screws or rivets z. The pivots of the levers are thus firmly held at both ends. To further stiffen the lever a, a marginal rib or web a is projected from the curved portion 0 of the main lever, between the pivots b and d as shown in dotted lines in Fig. 1. The levers also serve a third function, in carrying the threading die-holder which is shown with a plate Z carrying transfer guides m, m, adapted to fit between the levers when closed, as shown in Fig. 1, and such guides being dovetailed, as shown in Fig. 4, to receive pipe-dies p. Hooks or lugs q are formed upon the holder-plate to embrace the outer edges of the levers, and a pin 1" is provdied upon the holder to fit a hole 8 in one of the levers. Buttons t, t, are shown pivoted upon the guides m, m, and adapted to look over the faces of the levers a, c.

A socket u is shown in the plate Z of the die-holder, and the pipe-guide bushing v is shown formed with a hub 11 upon the forward end which fits this socket. The bushing is also formed with a flange w to fit the outer side of the plate Z, which flange has notches as which pass over the heads y of studs y set in the plate adjacent to the socket u. The heads of the studs serve to lock the holder to the plate by engagement with the edges of the notches as, as is shown in Fig. 1.

The dies being removable from the guides m, m, may be made with any sized cutting aperture to thread pipes of different sizes within the range or the tool; and the bushings 9. are similarly made interchangeable with the socket u and perforated to fit pipes of different sizes. A single tool is thus provided with convenient means for cutting off the pipe, for threading the same, and for screwing the pipe into fittings by means of the wrench jaws and is.

Having thus set forth the nature of the invention what is claimed herein is:

1. A pipe fitters tool having two handlevers jointed together, a cutter-arm pivoted upon one of the levers, and the other lever having a aw to support the pipe -to be cut and having a link connected with the cutterarm, the whereby cutter is moved toward the jaw when the hand-levers are pressed together.
