Adjusting` cone 84 further has a means for its rotation, as for in- 4s'tance'the Spanner holes shown. In order to adjust this tool, release locking means (nut on projection 85), rotate adjusting 'i sleeve`83 and adjusting cone 84 until the c utters are set to the size required, then tighten the clamping means and the tool is ready for use.

Referring particularly to the cutting tool shown in Fig. XI; this consists of body 87, of cutters 88, or'l adjusting sleeve 89, of adjusting ring 90, and of a clamping means. This tool is similar tothe tool shown` in Fig.

X-except that the ends of cutters 88 are square or perpendicular to the axis ofthe tool. The explanation of the adjustments- 93, of adjusting cone 94,.of lock nut 95, and of means -for securing said cutter block to said body, either rigidly or loatingly. Body 91 has a central slot-adapted to receive cutter A Lblock 92,r anda central opening 96, transverse to 'said slot, to receive said means for securing sald cutter block to sald body, which means consists of screw 97 which has a-'r'educed portion 98 to receive block 99;

said block 99 has two taper sides and two straight sides and is rotatably mounted upon the reduced portion 98. An opening is provided in cutter block 92 and Ablocks 99 fit therein. Thus it will be seen that when rotatingv screwl 97 one Way block 99 will be forced into said openingr in cutter block 92 and said cutter block will be secured rigidly to the body; Whereas lvvhen rotatingscrew 97 in the opposite direction block 99 will be forced out of said opening in cutter block 92 and said cutter block will he held ioatingly in said body, since the taper block movingAout of a taper aperture must leave a space `between said block and the Walls of said aperture as shown in Fig. XIII, and which space allows cutter block 92 to move laterally or' float. Cutter block 92 fits into said central slot, has grooves 100 to receive cutters 93, and has arectangular opening with two taper sides to receive block 99 as previously mentioned. Cutterblock 92 further has a plain and reduced portion to receive adjusting cone 94, and a reduced and threaded portion to receive lock r1 1 1t 95. f Cutters 93 t slidingly into grooves 100 and have one side beveled and adapted to the beveled side of grooves 100, the 'other side of cutters 93 isthreaded to engage' the threaded cone face of adjust ingr' cone 9.4. .Adjusting cone 94 has a central opening to fit said reduced'and plainI portion of' cutter block 92 and a threaded cone face to engage said threaded side of cutters 93. A means Jfor its rotation is provided, as for instance the spanner holes instance the spanncr holes shown.

shown. Lock nut 95 has a central and threaded opening to engage said reduced and threaded portion of cutter block-92, and turthcr'has a means for vits rotation, as for The arrangement shown in Figs. XII and -XTTI .may be modified as shown in Fig. XIV; this tool can be used as a rigid tool vonly and will not float` and the securing i. means of Fins. XII and XIII may be omitted; Body 91 is similar to body 91 except that the slot is 4narrower to accommodate the narrower cutter block 92, and that a -cutters l93.

but no threaded portion being provided on cutter blockl 92a. Glitters 93a 'are similar to. Adjusting cone 94 is similar. to adjusting cone 94 except that conical portion 94b is provided. Lock nut 95 is similar to lock nut 95 except that a conical'open-- ing is provided to tit over the conical portion of adjusting cone 94. This arrangement of adjusting cone 'and lock nut will lock the cutters and the cutter block at one operation. In order to adjust these tools, release

ylock nut

95 or 95, rotate adjusting cone 94 or 94a until the cutters are set tothe required size, then tighten lock nut 95 01'95 and the tool is ready for use.

Referring particularly to the threadingA die shown in Fig. XV, `this consists of body 101, of cutters 102, of adjusting ring 103, of

lock nut 104, and of retaining nut 105. Body 101 has a suitable shank and a central ro cess 106 to allow the object workedupon to pass in. Body 101 further has an jen-- 'threaded portion 91h is provided thereon,

larged portion with slots 107 to receive eut-' ters 102,'and a threaded portion at its front' end to receive retaining nut 105. Body 101 further has a plain portion to receive -adjusting ring;r 103, anda threaded Portion to receive lock nut 104. Cutters 102 t slidingly into slots `107 and have one side threaded to engage adjust-ing ring 103. Ad justing ring 103 has a' central opening to fit said plain portion ot body 101, andone`- threaded face to engage said threaded side on cutters 102. A means for its rotation'f'is provided, as for instance the Spanner lholes shown. Locknut 104 has a central and threaded opening to engage said threaded portion of body 101, and a means for its rotation as for instance f the `Spanner holes shown. Retaining nut 105 h a centraL- an'd threaded opening to engage said threaded portion of body 101, and a means for its ro# tation, as for instancethe jspanner'holes shown. Thexmethod of adjusting this tool should be easily understood from previousdescriptions. The cutters of this tool may. 'of course, `be placed singularly simiiar'to previous description and illustration, as will be obvious to anyone skilled in the"art. Graduation may be provided fon any of the tools so'that the amount of adjustment may be read. It will be seen that either the adjustinmmembor; or themeans for operating the `adjustin`g.,f1nember, or both, are located near the cutters orthe 'front `of the -tool whereby convenient accessibilityis attained. By Asuch an arrangement, lthe tooly may lbe adjusted while in the machine, thus `saving the time of removing the tool from the machine Whcn adjustingn the same.

The several modifications :shown and described' should enable anyone skilledin the art to malte and use any or all of said modiieations, as Well as design,` make and use incassi others which employ the 'spirit and intent of used; that the bodyfofijiiie cutters or cutter blocks may be placedat Vany angle to, or

` perpendicular to the axis ,of the tool; that the cutters or cutter blocks may bejplacedl so that-their cutting faces are either radial with the axis-of the tool, or radial and at an angle with said axis, or at an angle with the diameter (Fig. V) and parallel .with said axis, or at an angle with the diameter 0 the combination of a body 'having a plurality and at an angle with said axis, or A arallel with and in front or aheadof the dlameter (as seen in Fig. XIII for instance) andparallel with said axis, or parallel with and in front or ahead of the diameterandl at an angle with said axis; orparallel with and 'back' of the diameter (reverse or opposite of .the location of'cutter shown in' Fi XIII) and parallelwith said axis, or. para lel with and back of the diameter and atan angle With said axis. When placing the cut ters ahead of the diameter, a negative cutting-rake is given the cutters and such tools such tools are best adapted to operate upon steelA or similar'materials.v It is preferred that the cutters are placed at an angle, either with the axis of the tool, or With the diameter of the to'ol, or With both the axis and the diameter. It may further be noted that the adjustment of said cutters or cutter blocks maybe accomplished either by an adjusting cone or vby an adjusting ring/having a threaded face or faces adapted' and arranged to adjust the tool.4

n will be seen that in al1-oi the, modifications shown the sides jof said threads are vangularly disposed i'n relation to" the axis of the tool aswell as to the direction of the' v pressure brought upon thecutters by the locking means `When locking the tool; this is for the purpose of producing a wedging action to lock the cutters firmly and prevent'l lost motion.

I claim:

,s ing a conical screwthreaded surface thereon locking said adjusting members in adjusted' position; the sides of' said threads being inclined with respect to the axis oi said device to form Wedge-shaped seats for said cutters'upon said adjusting-member.

2. Ina device of the character described,

of slots, a cutter mounted in each'of said slots, the bottom of each ofsaid slotsbeing beveled to form a Wedgefshaped seat for onel edge of eachfof said cutters, one edge of each of said cutters being beveled to engage said beveled bottom of said slots, the' edge opposite side beveled edge being provided with threads, an adjusting-member having a screw-threaded surface thereon which is adapted to engage the threads-'upon said cutters, and means :for locking the said mear' bers in adjusted position; the sides of .said threads being inclined with respect to the axis of said device to form Wedgeshaped seats for the threaded edge of said cutters upon said adjustingmember. l

3. In a device of the chara'eterdescribed,

'the combination4 of a body having slots inclined to the axis of said body, a cutter mounted in each of said slots, each of' said. slots having a beveled bottom to form Wedge-shaped seat for one edge of each of said cutters, 'each oi said cutters havinga beveled edge to engage said beveled bottoni of said slots, each. o-said cutters .being pro= vided with threads upon the edge opposite. said beveled edge, an adjusting-,member hat' which is adaptedv to engage said tliucade upon said cutters, and 4means for locking the said adjusting-members in adjusted position; the sides oi' said threads being inclivid with respect to the axis of said device form Wedgeshaped seats for said cutters upon said adjusting-member.
