RICHARD J. ONEILL, OF LAFAYETTE, INDIANA, AND TIMOTHY BYRNE; OF BLOOMINGTON, ILLINOIS.
PlPE-CUTTER.'
SPECIFICATION forming part of Letters Patent N 0. 695,482, dated March 18, 1902. Application filed May 20, 1901. Serial No. 61,016. (No'modeL) To all whom it may concern:
Be it known that we, RICHARD J. ONEILL, residing at Lafayette, in the county of Tippecanoe and State of Indiana, and TIMOTHY BYRNE,residin g at Bloomington,in the county of McLean and State of Illinois, citizens of the United States of America, have invented certain new and useful Improvements in Pipe- Outters, of which the following is a specification.
Our invention relates to certain improvements in pipe-cutters designed especially for the cutting of pipes, boiler-fines, andthe like from the inside Where it is impossible to get at them from the outside.
To such end the invention relates to certain novel characteristics, a description whereof will be found in the following specification and the essential features more definitely pointed out in the claims.
In the drawings furnished herewith, Fig-- ure 1 is a side elevation, partly broken away, of the device in its preferred form. Fig. 2 is a vertical diametrical section in line 2 2 of Fig. 1. Fig. 3 is a detail horizontal section in line 3 3 of Fig. 2. Fig.4 is a similar section in line 4 4 of Fig. 2. Fig. 5 is a similar Fig. 6 is a vertical diametrical section in line 6 6 of Fig 5, and Fig. 7 is a perspective view of a cuttercarrier. Figs. 5 to 7, inclusive, are upon an enlarged scale.
Referring to the drawings, A represents a hollow casing in which is a feed-screw B, adapted to be reciprocated longitudinally within said casing to move the cutters to their work or detract them therefrom.
The feed-screw B is formed at one end with a squared head I) for engagement with a wrench or the like and at its other end with a wedgeb for engagement with the cuttercarriers C O. A non-circular guide-block D is secured upon the feed-screw below the wedge 19, which is guided in the longitudinal hole a in the casing. The threads b of the feed-screw extend to within a short distance of the wedge, and the shape of the latter in cross-section is rectangular, except that the sides 12 b are hollowed out or concave, as seen at b b to permit the cutter- 5o disks to move in said CODCZLVltlQS. The plane faces b b are formedwith grooves 12 '1) running parallel with the edges of the wedge, and these grooves receive overhanging guide edges 0 0' upon the cutter-carriers. (See Figs. 5 and 7.) These cutter-carriers are provided with openings 0 c to receive the cutter-disks 0 0 which are journaled upon pins 0 0 secured in the cutter-carriers. The wall of the casingA is formed with openings a or to receive the cutter-carriers, the latter being moved'therein by the action of the wedge in the cutting of flues, &c.
Beyond the openings at a the casing has secured to it an adjustablestop E,comprising, substantia11y,a sleeve e,encircling the casing,
a stop-plate e, and a collar e The stopplate 6 is free to turn upon the sleeve e and is held between a flange e upon the latter and the collar e The stop is fastened to the casing by screws c and by loosening said screws the stop may be moved along the casing to any desired point.
Upon the upper end of the casing A is secured at headF, turning freely thereon, in g which are pivoted dogs ff f adapted for engagement with the feed-screw B to move the same longitudinally. Thishead has screwed upon its lower end a ring G, against which rests the flange h of a sleeve H, said flange being confined between the lower endf of the head F and the ringG. A collar h oncircles the sleeve and bears against the ring G, and said collar and sleeve are secured to the casing A by screws h The dogs f f f are pivoted between their ends to the head F and have laterally-projectingfingersf threaded upon their ends for engagement with the threads upon the feed-screw B. They are held in engagement with'the feed-screw by cams it" 4?, Fig. 4, formed upon a cap I, which is slipped over the head F and is capable of a limited amount .of independent movement about said head. Other cams i t i Fig. 3, are formed upon the upper end of this cap for engagement with the upper ends of the dogs fff The cams t t" 11 and 2' i t are so arranged with respect to each other that when the cams t' z" t are in engagement with the lower edges of the dogs the upper cams will be out of the way, and vice versa. The cap is provided with a handle I for its rotation and with a slot 2', riding over a pin f in the head to limit its movement upon the latter.
A spring K is seated upon the cap I and bears against a nut 70, threaded upon the feed-screw, and is adapted to partially withdraw the feed-screw to detract the cutterdisks from the work.
The operation of the device is as follows: The feed-screw having been withdrawn sufiiciently to bring the cutteadisks within the face of the casing, the latter is inserted into the pipe or fine to be cut, so that the stop E rests against the boiler-head. The cap I is then moved into the position seen in Figs. 2, 3, and 4:, in which the dogs are thrown into engagement with the feed-screw. The further rotation of the cap in the same direction carries the head F around with it, and because of the engagement of the dogs fff with the feed-screw the latter is moved in the direction indicated by the arrow thereon in Fig. 2, thus forcing the cutter-carriers outward until the cutters come in contact with the pipe. A wrench or the like is then applied to the squared end of the feed-screw and the latter rotated, the disks cuttinginto the pipe and the head beingheld stationary by means of the handle I, the disks being thus moved outward until the pipe is cut through. It now the handle I be turned back slightly and then forward until the other end of the notch strikes the pin f the cams 2' t i will engage the upper ends of the dogs and release the feed-screw, the spring K quickly withdrawing it and moving the cutters away from the severed pipe. The device may then be withdrawn and the operation repeated.
