`ting tools for metal Working of the type having a head, provided with longitudinal `grooves errang-ed radially, and blades held 1n sind grooves.
y The object of the invention is to provide an improved tool in which the blades may be easily placed or removed; to provide 1m vproved means for fastening the blades in the grooves, said means consisting oi' Wedges which are driven in between the inclined, walls of the grooves and the inclined sides of the blades; and to provide improved means for the easy removal of seid pins keys, enabling `them to be quickly releema or backed 'out With these und other objects in ijieiv, the invention is hereinafter described and 'is :illustrated in the accompanying drawings, in Which Figure l is en elevation of the tool. Fig. f is e section on the line 2-2 of Fig. "l, Fig. 3 is e section on the lino 3 3 of l. Fig il is a, perspective ci? one ci the blades. Fig: 5 is a. perspective of one or the lockingp keys or pins. Fig. 6 is a partiel sectional View of e shell reorner forming e modification.
Referring specifically to the drawings, 6 indicates the shank of the tool and 7 the head thereof, reduced to form a neck 8 be 1tween the shank and the heed, through which neck are cross or diafmetricol bores or openings 9. The head is slotted lengthwise, the slotsbeing radially erranifed. The bock Wall l0 of each slot is flot and parallel to the axis of the tool. At its front Well, the slot has a groove 11 the surfaceot which is conical or curved and whichy "extends et an inclination tothe axis oit the tool, es shown at l2,- tapering inwardly vor toward the shank, and these grooves open at their ends into the cross bores 9 in the neck. The upper or inner ends of the grooves :ire closed oe shown at 30 to sustain the thrust or longi tudinel pressure on the blades.
The blades 13 are solid pieces of steel properly shaped to forro the cutting; edges,
t keys may sind these blades lit in the slots in the heed, The boclr of each blade is liet and rests' against the boel; wall i() olif the slot. llhe front well 'il of the blade is inclined or tapered od" toward the inner end thereof, with e shoulder 15 extending olong the t pered surface :uljacent the out; r edge of the binde. lil: ch locking pix, lli hos o curved or segn'lent-al surface ll lit the groove ll and has o, cated .sui-foce 18 to lit the adjacent inclined surface ll ot the blade, and the key long enough to project at its inner end, .into the cross bore 9, as shown in lge. l. rend 3. lllheo the blades are et opposite ifoints, the keys will project into each bore.
The tool is assembled by inserting.; the blades iny the slots end aflri'ving the Wedge keys intotlie key Way grooves endwise, tbe lrejvs thereby engaging; the blades 'with wei'lgng fiction und lookin-ftk the blades in the head. it is to be noter.. also, that the surfaces lil et the blades inc 1 as well :is iongitndinnllv end fore grip the blades wir e, litter action :is 'well ase. lonetndinol v' tion, the engaging sur i.' ele to the radins :is woll es to the heed. llhie locks the blades egoinst either longjitwli ,il or radial rement, pressing; the iirmljv to t 1r l n' against oc bock ,and innervells or the @lo in importent feature oi' the const-rr follows 'iro-m the projection oi the inner ends oi lie keys into the bores 9, Afor f be easily loosened. by inserting e, bevel tool or ber into the seid bores, to loosen and' irnoclr oiitthe keys and permit tbe removel of the blades, end the knocking out tool will oct directly on the ends oit" the lieve ln the modification simon in Fig. tl the shell Si@ hee e eircomlerenfini` ilengjfe ill. et the opper en( s ci? the grooves in which the keysere inserted, and the upper or inner ends of the lief/s extend through suitable -lioles in seid flange, es shown et 2Q', per" netting the lreys to be topped und. loosened by o herinner or the like, for the purpose el removing; the blades.
