Application filed January 18, 1905. Serial No. 24:1,364.

To no who/7t Ill; 'IIMIJ/ concern:

Be it known that it, ROLAND D. Go'uLn, a citizen of the United tltates, residing at l-lood ltiver, in the county of i Vasco and State of Oregon, have invented certain new and useful Improvements in Drifting-Tools, of which the following is a specification.

This invention relates to improvements in d rifting-tools of the type commonly employed by plumbers and other mechanics for drifting tubular bodies, such as pipes or the like.

The tool comprising this invention is primarily designed for swaging or drifting ends of lead pipe to flare such ends for fitting purposes.

The object of the invention is to construct the tool in such a manner that the same is of hollow formation, whereby it may be utilized as a receptacle for holding paste, grease, soil. or any similar articles incident to the kit of the mechanic, and at the same time the tool is provided with a cutting device forming a part thereof and readily adapted for cutting washers or similar articles, such as are always needed by a mechanic in his operations.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.

While the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the essential features thereof, still the preferred embodiment thereof is shown in the accompanying drawings, in which Figure l is a perspective view of a tool embodying the essential features of the invention. Fig. 2 is a vertical sectional view. Fig. 3 is a perspective view of the cap or plug forming a part of the tool.

tlorresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters. Y

The drifting-tools ordinarily employed for flaring or drifting ends of pipes comprise a body of approximately conical formation adapted to be driven into the pipe to thereby expand or spread the metal in accomplishing the desired result.

As shown in the drawings, in general structure the invention consists of a tool the body 1 of which is of approximately conical forma tion, said body, however, being made hollow in order that the same may be utilized as a receptacle in order to receive such articles as above mentioned. The body 1 is open at its larger end, and the opening aforesaid is normally closed by means of a cap or plug 2. To admit of attachment of the plug or cap 2 to the body of the tool, the latter is internally thread-- ed at its open end, as shown a113, and matching threads 4 are provided exterior of. the cap 2, admitting of screwing the cap into the body of the tool in a manner shown most clearly in Fig. 2 of the drawings. The cap 2 is of hollow formation, being provided with a recess '7 upon its under side, and the walls of this recess '7 diverge oiiitwardly to the inner extremity of the cap, so as to form an annular cutting edge 5 at such portion. The annular cutting edge 5 of the cap is designed for use in cutting washers or similar parts and is of course well protected when the cap 2 is in position upon the body 1 of the tool. Between the inner and outer ends of the cap 2 is formed an annular flange 6, which isadapted to overlap the larger end of the body 1, so as to form a more perfect closure and at the same time afford the cap a rigid bearing against the body 1, so that when the tool is struck when forcing the same into the end of the pipe the force of the blows received upon the cap 2 will thus be removed from the threads El and l.

The tool is of extremely simple formation, and the whole body 1 reinforced in the driftingoperation by means of the cap 2. The contents of the body 1 when the latter is used as a receptacle may be had access to by removal of the cap 2 in a manner apparent. W hen the cap 2 is removed, the latter may be utilized as a cutter in the manner before premised, the structure of the tool obviating the use of several different devices for accom- ')lishing the functions of the parts thereof.

The cap or plug 2 is provided at its upper side with a V-shapcd opening ti, through which a cord may be passed and knotted, so that the tool may be used as the bob of a plumb-line. The shape of the tool admits of readily adapting the same for this last-mentioned purpose.

Having thus described the invention, what is claimed as new is 1. A. drifting-tool comprising a hollow body open at an end, and a cap fitted to the open end of the body and provided with a ret upon its under or inner side, the walls of said cutting edge at the inner extremity of the cap and housed by the body of the tool, and an annular flange projected from the cap and abutting against the open end portion of the body of the tool.

In testimony whereof I afiix my signature in presence of two witnesses.
