Application filed June 2,
To all whom it may concern Be it known that I, P m J. Kinina and resident citizen of the United States,
oi' lvlilwaukee of Milwaukee,v in the county and State of lVisconsin, have invented cerv tain new and useful Improvements in Pipev (hitters; andl do hereby declare that the i cllmving' is a full, clear andexact descrip- 'tlOD tl18i'6OT. v
My invention relates to a. new and improved pipe cutter which is more specially adapted for cutting soil pipe after it has been installed.
in the construction of modern buildings in which the bath room is usually finished with a cement or tile floor, itis necessary to set the soil pipe in positionbeiore the floor is finished. It has been the custom to-cut the soil pipe at'the proper length before it is connected. This has caused considerable dissatisfaction since the cement or tile workers cannot always be depended upon to finish the floor at the level which the plumber, and as a consequence thepipe will be too short or too long.
It is the principal object of my invention to provide a practical device by which the end of the pipe may be cut oil? after the floor has been completed.
It is a further object of the invention to provide suitable means by whichthe point at which the pipe is cut maybe accurately determined.
A. still further object of the invention is to provide means forfacilitating the removal oi": the tool from the pipe after the cutting operation has been completed.
.With the above and which will be apparent from the following description, the invention consists in certain details which will be described in connection with the accompanying drawing in which, 7 V j V Figure 1 is a vertical transverse section through the tool disposed in operative position.

10, whereby the plate is revolubly supported. 7
1 1 cylindrical blocli,
instance is composed of three sections, '11,
11 and 11", is supported by the. plate 10,
each section being provided with a screw which is tapped into the section and shdably secured in the slot which, in the present the upper end of 13. a Each section is also provided with, a
'screw it on whichis rotatably mounted a cutter 15. The sectionsot the block are held by the springs 'tensioned soas to urge the sections towards their innermost position. Extending axially of the block is a tapered opening which receives the tapered core 18, the several sections of the block being keyed to the coreby, means of a key is provided with a stem 20 which projects upwardly through the sleeve 7 and is provided with a non-circular portion 21 on which is fitted the handle 22. A washer 23 may be provided between the handle and the end of the sleeve 7. In order to move the core upwardly and expand the block, the upper end of the stem is threaded, as shown at 24 and provided with a wing nut or the like, 25. in the operation of my device, the core 18 is lowered. by unscrewing the nut 25 sufficiently to permit the block to be inserted in the end of the pipe. The sleeve 7 is then adjusted vertically to bring the cutting element to the point at which 16 and 17, whichare.

it is desired. to cut the pipe and the sleeve is secured in this position by means of the set screw 7 The cutters are then revolved, as it will be readily understood, by means of the handle 22 and from time to time the block is expanded by turning up the screw 25 in the usual manner. T is operation is continued until the cutting is completed. The screw 25 may then be turned to release the core 18 and permit the block to contract. It will be seen, however, that owing to in cutting the pipe, the core will be wedged tightly in the block. In order to facilitate its removal from the pipe, an upward pull may be exerted on the sleeve 7 or the tripod after the nut 25 has been loosened. At the same time it may be desirable to deliver a slight blow on the end ofthe stem. This the force exerted will atonce result in the block moving upwardly in respect to the core and. consequently permit the Same to contract under the influence of the springs 16 and'17, and thus be readily removed.
While I have shown the ribs 19 midway of the respective sections it may be advisable to locate them at the edges of the sections to permit a relatively larger cutting element to be used. The vertical dimensions of the sections should: be relatively short soas to permit the use of the device where there'is an elbow in the pipe immediately below the floor. that the structure herein described is for the'purpose of illustration only and that my invention comprises all equivalents which are'in'cluded within the scope or the appended claims.
I claim:
1.v A pipe cutting tool for cutting soil pipe and the'like, frame adapted to rest upon the floor, a vertically disposed sleeve adjustably supported in said frame, a cylindrical block revolubly supported. at the lower end of the sleeve and provided with cutting elements,.said block being composed of sec- 'tions, each radially movable With respect to the sleeve, resilient means for normally holding said sections in their innermost It will be understood,
comprising a supporting positions said block being formed with a tapered bore,- a tapered expanding member adapted to be received in said bore and having a stem extending through said sleeve, means for moving said expanding member longitudinally to force the sections of the block outwardly and tating said block to render ments operative. a
2. A pipe cutting tool for cutting soil pipe after it has been installed comprising an expansible cylindrical block adapted to be inserted in the pipe, said'block being divided radially into a plurality of sections, a channel extending circun'iferentially around the block, means for supporting and guiding the sections for radial movement, a circular spring seated in the channel and urging the sections inwardly, ments carried'by the several sections, means for supporting the block at a predetermined height in the pipe, means for rotating the the cutting elemeans for ro-V cutting elesame," and means for forcing the sections outwardly against the resistance of the spring.
