ROLAND l). GUULD, OF HOOD RIVER, OREGON.

Specification of Letters Patent.

Patented Aug. 15, 1905.

Application filed January 16, 1905. Serial No. 241,865.

To all whom it may concern.-

Be it known that l, RoLAND D. GOULD, a citizen of the United States, residing at Hood River, in the county of VVasco and State of Oregon, have invented certain new and useful Improvements in Drift-Plugs, of which the following is a specification.

This invention comprises a novel form of drifting-tool for use in drifting damaged hollow bodies, such as pipes.

The invention consists in the provision of a device of the above class of such a construction as to provide a receptacle readily adapted to receive material which may be used by a mechanic in his operations or articles which may be comprised in his working kit.

The invention includes, further, a special construction of tool whereby hollow punches or cutters are formed which admit of ready cutting of washers or gaskets or similar articles without necessitating the use of a separate tool device for accomplishing the operation.

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 spirit or essential features of the invention, still the preferred embodiment thereof is shown in theaccompanying drawings, in which Figure 1 is a perspective view of a tool embodying the invention with parts separated. Fig. 2 is a vertical central section of the tool. Fig. 3 is a side elevation of the cap-closure forming a part of the tool.

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

The tool which constitutes this invention is of that type used by plumbers in operating upon lead pipe and i. lt(.ltt]')t0l to be forced into the pipe in order to true damaged portions thereol in a manner which will be readily understood by those versed in the art to which the invention appertains.

licnerally describing the device, the same comprises a hollow body l of approximately cylindrical form, closed at one end and open at its opposite end. The open end of the body 1 is adapted to receive a cap or like part (designated 2) by which said end is closed in order that the body of the tool may be readily utilized as a receptacle. The open end of the body 1 is provided with internal screw-threads 3 a short distance from the extremity thereof, and these screw threads match other threads l, provided upon the exterior portion of the cap 2 aforesaid. The cap 2 is reduced, as shown at 5, so as to readily be received in the body 1, the reduced portion of the cap having the threads at thereon. The open end of the body 1 at the eX- tremity is beveled outwardly from the threads 3, as shown at 6, so as to form a cutting edge 7, the latter being of circular form. since the body 1 is preferably of cylindrical construc tion. In order that the beveled portion 6 of the bodyl of the tool may lit snugly against the cap 2, the latter is formed with an inclined shoulder 8, which joins the reduced portion 5 of the cap with the body of the latter. The cap 2 is of hollow formation, having a recess 9 upon its inner or under side, and the walls of this recess 9 diverge outwardly to the inner extremity of the cap to form a cutting edge 10 of a size somewhat smaller than the cutting edge 6 of the body 1 and substantially of a circumference the same as the internal circumference of the body 1 aforesaid. The cutting edges 7 and 10 are utilized for cutting washers or gaskets when the parts 1 and 2 are separated, and since the parts of the body 1 and the cap 2, having the cutting edge aforesaid, are not of the same size it will of course be readily appreciated that different-sized washers may be formed by proper operation of the cutting devices.

The interior threads 3 of the bodyl are designed to be of a standard gage in order that piping may be threaded to the body to form a means for forcing the tool into hollow parts in rectifying damaged portions thereof. The tools above described are usually made in various sizes. However, this is not essential Within the contemplation of the invention. The cutting edge 10 of the cap 2 is well housed when the cap is positioned upon the body 1, and thus the cutting edge 7 is also protected, since the threaded extremity of the body 1 is flush with the sides of the cap 2, this allording a protection for the edge 7 in a manner which will be readily seen.

Having thus described the invention, what is claimed as new is---- 1. A drifting-tool comprising a hollow body open at one end, the open extremity of the body being formed with a cutting edge, and a cap threaded into the open end of the body, said cap being provided with a recess upon its under side, the Walls of which diverge outwardly to form a cutting edge of a size smaller than the cutting edge of the body aforesaid.

2. Adrifting-tool comprisinga hollow body of approximately cylindrical formation open at an end thereof and closed at the opposite end, the open end of the body being provided with interior threads some distance from the extremity thereof, the extremity of the body at its open end being beveled outwardly from the threaded portion aforesaid to form a cutting edge, and a cap fitted to the body and provided upon its under side with a recess, the walls of which diverge outwardly to the inner extremity of the cap to form a cutting edge, the inner extremity of the cap' being reduced and provided exteriorly with screw-threads to match those of the body of the tool, the cap being further provided with an inclined shoulder abutting with the beveled extremity of the body to thereby afford a protection for the cutting edge of the latter.

In testimony whereof I affix my signature in presence of two witnesses. 7 ROLAND D. GOULD. [L. s.] Vitnesses:
