features of novelty and advantage.
An embodiment of the invention is illustrated in the drawings in Which- Figure l is acentral vertical section, and Fig. 2 is an end View. Fig. 3 is a transverse section on the line 3, 3 of F ig. 1.
Referring to the drawings a denotes a spindle having a plurality of longitudinal slots -b tapering to provide the greatest depth at `the end of the spindle. c is an adjusting collar rotatably mounted on the spindle but held against movement longitudinally of the spindle by the shoulders 1 2, the sleeve being interiorly threaded to re ceive the threaded end of the cage d which lits closely upon the spindle, the spindle of course, being of even diameter throughout,
except for the tapered grooves. The cage is slotted as at 5 to correspond to the grooves in the spindle and has reduced and threaded ends. The inner end is engaged by the adjusting sleeve c and the outer end by the pilot Cutters g having their loweredges tapered to correspond to the taper of the bottom of the grooves in the spindle rest in these grooves and project through the slots in the cage. The ends of the cutters are chamfered olf to an angle of about .fortyiive degrees and are engaged at their outer ends by tbs". undercut pilot and on their inner ends by a lock sleeve k. f
The adjustment is secured by loosening the lock sleeve and then turning the adjusting sleeve in either direction which cruises the spindle to move in or out of the cage, thus raising or lowering the cutters; When adjusted to a sufficient degree the lock sleeve is turned up to hold the cutters in position.
The set of cutters shown provides for a variation of about one-sixteenth of an inch in diameter but with the same device another set of cutters of greater depth can be used so as to provide for an increased size. lVhen the size of the cutters is changed the pilot is usually changed to correspond Vso that for hand operation it will act as a guide.
Features that will be particularly noted are; that the faces of the cutters lie in raf dially disposed planes; that the spindle is supported by the cage against any tendency,
to spread; the construction is suoli that there is no part projecting from the front ot the tool making it possible to ream out bottoined holes; and the cutters are supported both in the spindle and in the cage making it possible to bring the suppe-rt up vnear to the cutting edge and so prevent any spring in the cutters. I desire to secure herein such modifications as come fairly within the scope of the claims. f
I claim as my invention l. In an article of the character described,
a driven spindle having longitudinally extending and tapered grooves, a cage closely lit-ting said spindle and having correspond?` Y ing slots, cutters, having their bottom faces tapered to correspond Withthe taper of the grooves in the spindle, seated in said goove and projecting through the slots in the Mge, means for moving said spindle and cage longitudinally with respect to one, another to cause radial movement of the cutters, and means adjustably engaging the cage for holding said cutters securely in position.
2. A spindle having longitudinally extending and tapered' grooves, a cage closely fitting upon seid spindle and slotted to correspond with grooves in the spindle, reduced and threaded end vportions on said cage, a pilot secured to `the outer end of the cage and a. lock sleeve secured `to the inner end of the cage, cutters seated in the grooves in the spindle and projecting througli the cage and engaged by said pilot and lock sleeve to hold them in position, an adjusting sleeve rotatable on the spindle and engaging the cage whereby the spindle and cage are moved longitudinally relative to one another for the purpose specified. v
3. In an article of the character described a spindle having a plurality of longitudinal grooves whose bottoms taper toward-the. end of the spindle, a cage fitting closely upon .said spindle and slotted to correspond with the grooves therein, cutters Whose bottoni faces are inclined.` to correspond With the tapering of the grooves, said cutters being seated in saidiv grooves -and projecting nall)T with respect to said cage and cutters,
.through the slots in said cage, means the plane of one face of each cutter being mounted on the cage and engaging the ends radially disposed. l of the cutters to hold thein in position in WILLIAM G. CHURCH. said cage and an adjusting sleeve rotatable `Witnesses:
