COMBINED PIPE-VISIE AND PIPE-CUTTER.I

Specification of Letters Patent.

Patented Dec. 3,1912.

Application led' January 14, 1911. Serial No. 602,636.

To all fwhom 'it may concern:

Be it lmownthat-I, CHRISTIAN BRACK,4 a

citizen of the United States, and aresident` ing screw-threaded and also for cutting such, 'pipe in different lengths. The body of theY tool maybe tem orarily clamped upon a bench, table, shel or other support, and a detachable, reversible lever is -pivoted to such body and adapted for use both in pipothreading and cutting, according to the position in which it is placed.

In the accompanying drawings, Figure 1 isa side view of my improved tool, the same being shown applied and secured to a bench or table. Fig.' 2 is a plan view, save that a lportion of) an' adjusting screw is shown in section. Fig-3 is a perspective view of the jaws of the ratchet bench or table clamp. Fig. 4 is mainly a longitudinal section of the tool showing it secured to a bench or table. Fig. 5 is a vertical cross sectionon the line 5 5 of Fig. 4. Fig. 6 is a perspective view of the smooth jaw for holding nickel-plated or other ornamental pipe.

' Referring, in the first instance, to Figs. 1 and 4, A indicates the body of the tool, B,

the body in both clamping and cutting pipe, while C is a supplemental hand lever adjustably connected by a screw and nut D with the said reversible lever.

The body Ais formed of cast metal and has suiiicient weight and size for its function. The base or underside ofthe body A is flat so that it is adapted to rest upon a bench or table. At its-larger end'it is provided with two holes 1, adapted to receive the pivot 2 of the lever B. Adjacent to this portlon it. is provided with a notched, or ratchet, fixed jaw 3, and adjacent to this portion 'it is further provided with two rotary and beveled 4steel pipe-cutters 4, which are journaled in a longitudinal slot or groove of the body.

The detachable and reversible lever B has lan enlarged head 5 provided at each end to the angular jaw 3 of the body A; and again, at a point farther removed from the pivot, it is provided with two transverse bearing rollers 8, which are so arranged as to come into direct contact with a pipe laid 'upon the rotary cutters'4, thus serving to hold the pipe while permitting its rotation with comparatively little friction.

I The lever B is operated by a hand-lever C, which is pivoted at 9 to the body A and adjustably connected with the free end of-` the lever B. by means-of the screw D and wing-nut 10, said free end of the lever B being slotted to allow convenient insertion and removal of theA screw.

The pivot end of thel hand-lever C is arlranged in a longitudinal groove of the body A and provided with an extension or toe 11, which, when the said lever C is raised :at the inclination shown in Figs. 1 and 4, #rests and bears upon the body A. When in this position, therefore, the lever C provides =a fixed point of attachment for the screw D, and, if a pipe or y be inserted, as shown Figs. 1 and 4, between the opposing jaws, may be clampedl as rmly as required by 'turning the wing-nut 10; for, .without resorting to this expedient, a variable hand pressure may be applied by pressing down :on the lever C, which will draw'the rcversible lever B :down more firmly on the pipe or y. 5 It is thus within the power of the operator to clamp a pipe with a'moderate degree 'of force, as by use ofthe nutand' screw, or a much greater force may be applied through the medium of the lever C and the screw attachment. v a

It will be' understood that, when it is required to lay a pipe on the body A in the angular jaw 3, the screw D and its attached nut l0 may be removed or swung outward from the lever B, and the latter is thus left free to `be swung upward. The same is also true with respect to the insertion of a pipe between the lever B and the cutters 4.

In Fig. 1, the lever Bis shown provided with an angular ratchet jaw 7 corresponding to the jaw 3 of the body A, such construction being common in pipe-wrenches for holding rough-faced pipe. If a pipe to be cut' is of sufficient diameter, the lever B may be pivoted in the lower hole of the body A; but, if the pipe is small, the head of the lever B will be adjusted so that the pivot pin .2 will pass ythrough the lower hole 6 in its head.

By observing Fig. 4 it will be seen that the lever B has been reversed position, `that the numeral 12. "`he body or lower portion,

13 of such jaw is so constructed as to fitv into a socket formed in the body A and is thus held securely in place while in use. A pipe y is showan in Fig. 4 as arranged between the jaws 3 and 12.

The tool thus far described may be used for threading or cutting pipe held in a vise of any suitablecharacter, vthe tool bein applied to the pipe and moved around lt-by hand in a well known manner, or as usual with a large class of` pipe-tools. In such case, it is obvious that the tapered, grooved and extended shank of the body A would,

serve as the handle; but ordinarily, the tool will be used as an attachment of a bench, table, shelf, or other support, and for this purpose it may be clamped at one end and secured by a screw at the other. The clamp I employ is particularly ada ted for its function, the same consisting o two ratchet jaws 14 and lf3- see especially Fig. 3. The jaw 14 is right-,angular in form, one wing having a screw hole and the other a slot and also ratchet teeth at 14?' on its innerl side. The other jaw 15 is also right angular, one of its .arms having ratchet teeth 15 and also a screw opening, while the other arm is provided with a winged clamping screw 16.

As shown in Fig. 4 a screw 17 is applied to the jaw 14 and secured by a nut to the body A through whichl it passes; and, as will be further seen by observation of Fig.

1, the other jaw, 15, isengaged with the jaw 14 by means of another` screw 18, and the clamp-screw 16 is screwed up against the under side of the projecting ledge of a bench or table. This means for detachably securing the tool to a support may ordinarily su'flice without the aid of a screw inserted through the opening 19 in the extreme end of the shank. It is obvious that the jaws A14 and 15 ma be adjusted vertically with relation to ea' other in order to accommodate bench or table ledges of dilerent thicknesses.

InvFig. 1, the clamp is shownarranged in alinement with the body A of the tool, ibut in Figs. 4 and 5 it is shown arranged at right angles thereto, but the means and the manner of securing the clamp to the body A and to the table remain the same. The to'ol thus forms a xture of the support while in use, but may be readily detache when required for any purpose.

It will be seen that by the construction and combination of parts described and illus# trated in the drawings, I provide a single tool capable of diierent functions and which is distinguished by simplicity, effectiveness,

Aand adaptation for convenient application of a great degree ofvforce.,

What I claim is In a tool of the type indicatedthecombination with the horizontal boy having its larger end 1provided with transverse holes located at di erent heights for receiving a pivot pin, and having a jaw portion and rollers arranged as shown, of a reversible lever having an enlarged head, each end of CHRISTIAN BRACK Witnesses:
