CUTTER-TOOL'.
SPECIFICATION forming` part f Letters Patent NO. 663,455, dated December 11, 1900.
I Application filed December 18, 1899- Srial No. 740.819. (No modelJ cylindrical holes in metal bodies of any form or character; and ithas for one of its objects to provide a tool of this character the cutters ofy which may be readily adjusted to operate upon tubes of diderent diameters or to rearn out a tube of a given diameter to diiferent depths means shown in the accompanying drawings,
in which- Figure 1 is a side elevation of the cutterhead and cutters mounted in a suitable holder in operative position, the holder and a tube upon which work is to be done being shown partially in section and parts being broken away.
central longitudinal section through the cutter-head, taken at right angles to that of Fig. 2. Fig. 4 is a detail sectional view of a portion of the cutter-head, showin" the cutter and its adjusting and locking device in dif` ferent positions from those represented in Figs. 2 and 3.
Referring now to the details of construction illustrated in the drawings, the holder or boring-bar l has a tapered end portion 2, adapted to be inserted in a lathe-chuck or boring-lna-- chine clamp in order that the holder may be Fig. 2 is a central longitudinal sec-A tion through the cutterhead;l and Fig. 3 is ay properly centered and `rigidly held for rotation.- The central portion of the holder is provided with a rectangular opening 3, eX-
' tending through it from side to side, in which located a cutter-head 4, the latter'being provided with a central opening 5, through which extends a pin 6 of smaller diameter, this pin and opening'serving to retain the cutter-head in the holder, but by reason of the difference in diameter between the two permitting the head to move back and forth in its seat suiiciently to adjnstitself with reference to the material operated upon. p
The head 4 is provided at each endy with a slot-7, in which ts a substantially circular cutter S, having a sphericalicutting `edge 9 and a central tapered opening 10. lIn employing the term spherical to define the form of the cutting edge I mean to indicate that the'cutter isAin the form of a segment Yof a sphere having parallel circular sides of different diameter. While the 'cutters employed by me are shown as circular in form and the functions performed render the circular form `partic'ularl y advantageous, I desire and intend to include within the scope of my invention all variations from the circular form that do not rob the cutter of its essential functional characteristics. A screwthreaded opening l1 communicates from each slot with one side face of the head, this opening being arranged at right angles to the slot 7, Seated in each screw-th readed opening 11 is a screw 12, having a tapered inner end of such form and size as to lit the.
tapered openingvin the cutter. Extending longitudinally from the base of each slot 7 ing 15 extends outwardly at right angles I thereto lto one of the edge faces of the head, and in this opening is seated a screw 16, having a tapered inner end, the base of the opening being tapered tocdnform to the end of the screw. In order to set the cutters in operative position, the screws 12 and 1G are screwed home, so`as to hold the cutters rigidly in the head. If it is desired to increase the diameter ofthe cut, the screws 12 are loosened and in the slots 7, as will be readily understood.l
The screws l2 'and 16 and the pins 14- are made of hardened steel, and therefore servev to hold the cutters securely in any position to which they may be adjusted. In case the two cutters are not adjusted to exactly the same distance from the center of the head the play between the opening 5 and the pin 6 will enable the head'to automatically adjust itself to the work.
It will be seen upon reference to Fig. 1 that the tube 17 is cut by only a comparatively small portion of the spherical cutting edge of each cutter 8, and it therefore is feasible to securela large number of substantially new sharp cutting edges without grinding the cutters or'substituting new ones therefor, but merely loosening the screws 12 and partially rotating the cutters to bring a new portion of the cutting edge into working position.
The tool constituting my invention and here described and illustrated may be ad vantageously used in any style of lathe, drillpress, or boring-mill and is both a right and a left boring-tool, as will be readily seen.
While I have illustrated and described my invention as embodied in aspecitic structure, I desire it to be understood that the details as regards form and relative location of parts may be varied withinconsiderable limits without departingfrom the spirit and scope of my invention.
What I claim as myinvention, and desire to secure by Letters Patent, is-
1. A boring or reaming tool comprising a cutter head, a circular cutter rotatably mounted therein on an axis at right angles to and not intersecting the axis o f the head, means for adjusting the cutter to different distances from thecenter of the head and means for locking the cutter immovably in any position to which it may be adjusted.
2. A boring or reaming tool comprising an oblong head. having end slots and screwholes communicating laterally with said slots, circular cutters having central conical apertures and seated in said slots and screws having conical ends .nd seated in said holes and projecting into said apertures.
3. A boring or reaming tool comprising an oblong head having end slots, a screw-threaded opening extending from each slot to one face, a .recess extending longitudinally from the base o f each slot toward the center of the head and the screw-threaded opening extending from the base of said recess at right an gles thereto, a piu in said longitudinal recess, circular cuttershaving central openings and seated in said slots and screws having tapered ends and adjustable insaid screw-threaded openings to adj ust said cutters and lock them in position.
4. The combinationv with a holder, of an oblong cutter-head'mounted therein and provided at 4eachnsnd with a rotatably-mounted circular cutter Aand with ineanslfo'r adjusting the cutters toward and away from the holder and for locking thgm in any position towhich they may be adjusted. j
5. A boring or reaming tool comprising a holder, an. oblong cutter-head mounted to center itself in said holder, and a circular cutter rotatably mounted in each end of said head.
6. Aboring or reaming tool comprising holder, an oblong cutter-head mounted to center itself in said holder,a cutter `mounted in each end of said head, and means for adjusting the cutters toward and away from the holder.
7. The combination with a holder having a transverse slot, of acutter-head mounted to center itself in said slot, said head having a circular cutter rotatably mountedin each end and means for adjusting saidv cutters toward and away from the holder and for locking them immovably in any position to which they may be adjusted.
8. A boring or reaming tool comprisinga head and a circular cutter mounted therein on an axis at right angles to but not intersecting the axis of the head, said cutter being adjustable on its axis and also toward and away from the center of the head.
In testimony whereof I, the said KARL O. MUEHLBERG have hereunto set my hand.
