Figure l en elevetion et Ynuyputter, shown in operative engagementy withv a pipe Figure 2 is a View similar to Figure '1,
parts being broken away and shown in section, and t e several parts of the cutter'ring being shown disengaged.
Figure 3 is an axial section through Figure 1.
Essentially my cutter comprises a handle 3, tl ring k2 and various pipe engaging and Cutting elements eerred' bythe 'ring es thehutting disltll. 'andthe rollers lOtio'r supporting the pipelD opposite the cutting" i disk. 1.- The handle 3 Ifhave shown es hi? 00 fureated et one end, the hitureetion being indie-ated at 30- f 'The ring 2 is ,iorniedvvithf grooves. 20 extending about it, and the lefureeted. end oi the lilonelleisprovided with Y eert the rinafron the' eendlezforioeeen about its tenter- I have provided ratehet snneetion i tween the handle- 35 and-ring2 .vvheh may be 0f eey desired This l have shovvfn' 7 es e' sprng'pressed rdog niounted in the handle 3 endfengeging teeth 23 formed in the periphery ofthe, 'ring' 2;- It shouldbe understood thetthedee iS positonedet one .side ofthe -hituroete'd endet the handle? and dees :not obefiuet Q th'e hiureatien idf therein` The ring 2 ments which are hingedly feon'fneoted hyf'e pin Qne oit thefs'egriiente, no2@ he 'easilyde-taoheddrorn the other segment 25; f endthe segment. 261;' preifereblyoei-freies' the,

It is essential, ofcourse, that one these i, elements be movable relative to the'ring,v
although the other, as, forv instance, the roll-' i. ers 10, might if desired be fixed thereto. v
However, I have shown the disk 1 as journaled in an arm 11 pivoted at 12 to the segment 24, y1 have also shown the rollersl 10 as 10ov I journaled in an arm 13 pivoted at 14 to the same'segment 24.
A set screw 15 threaded in the segment'24 may be turned to adjust theposition of the.
form of this head may be varied in any manner desired, care being taken that the head shall not be of .a shape that willv not pass through the bifurcation 30.
VHowever, I prefer that it be lformed in such manner as to accommodate a socket wrench 40 which is secured at the end of a rod 4, reciprocable in a bore 34 in the handle 3.' The rod 4 lat its upper end projects from the end of the handle and is provided with a suitable handle 41 enabling itA to be. turned easily. Thus, whenever ythe bolt 16 is in line Vwith the rod 4the socket wrench 40` may be depressed to engage the head 18 of the bolt and the bolt can then be adjusted to control the position ofthe cutting disk 1. Obviously, the wrench 40 may be of a shape to engage any shape of yhead which is rotatable in the bifurcation 30.
Vhen it is desired to inserta new pipe,`
the latch 26 is released and the segments I24 and25 swing apart. The bolt 16 and the screw 15 should be retracted and then the pipe is inserted. Due to retraction of the bolts 15 and 16, the pipe can be moved to one side to give sufficientv room for the latch 26 to close. The bolts are then adjusted to engage t-he pipe with the cutting disk 1 and the rollers 10 and by rotation or oscillation of the handle 3, the ring 2 is rotated about the pipe. without the ratchet, by rotating the handle 3 entirely about the pipe with the ring 2,
or'the ratchet dog 33 may be brought into` operation. If it is desired to remove the cutting disk for sharpening or forl any other purpose, it is a simple matter to'remove the segment 24. ,The rollers 10 can alsol be replaced inthe same manner if they become damaged. l
The device may be' used *eitherI For cutting quite small kpipes an auxiliary block 5 may be employed. I have shown the arm 11 as dove-tailed at 19 upon its upper surface, to receive a corresponding groove in the block 5. When the block is secured on the arm 11 it is interposed between the arm and the bolt 16, and moves the cutting disk closer to the rollers 10 by the thickness of the block.
vWhat I claim as my invention is: y
1. 'A pipe cutter comprising a handle biurcated at one end, a ringfguided in said bifurcated end for rotation about its. Acenter, ratchet means connecting the ring yandv handle, pipe engaging and cutting elements carried by said ring, a screw threaded inj" said ring and engaging the cutting element to control itsposition, the head of said screw projectingfrom the peripheryof said vring and passing through the bifurcation of the handle as the ring is rotated relative thereto, and a socket wrench reciprocably mounted in vsaid handle and engageable with the head of said screw to turn it when thetwol are brought into registry.
2. A pipe cutter including a ring rotatable about its center, said ring vbeing formed.
of two hingedly connected segments, and ai latch pivoted upon one segment and engag ingT the other segment to secure theirfree endstogether, and movable toward the centerpofthe ring to release.
.3. A pipe cutter ,including a ring rotatable about its center, said ring being'formedv of two hingedly connected segments, a`
latch connecting the free ends of the two segments, an arm carrying a'cutting disk and .pivoted upon one of said segments, a
second arm pivoted upon 'the same `segment"v Opposite said cutting tool, a bolt threaded in the ring and engaging the arm to control the position ofthe cutting tool, and
an auxiliary block adapted to be interposedl between the bolt and the' arm, said arm and block having interengaging block-support-` ing means.
