In these drawings, 1 indicates the shank of the 13001 adapted to be connected With the driving spindle in any suitable manner. This shank has a head 2 provided with a concaved face formed substantially like the segment of a sphere. From this concaved face two pins 3 project into radial S1ots or openings 9 in a coupling piece 01 compensat1ng rnember 8 Wh10h has a convex fzmce eorrespondmg 111 curve er spher1c1ty t0 the conczwed face 0f the fiange or head 2. This compensating piece also receives pins 10 pro- ]e'cting from the concaved face 7 0f the die carrying piece 4. This die carrying piece is held to the head er flange 2 by a hub o1 cap pieee 11, Which is provided with a fiange at 12 overlapping the flange 6 of the die earrying piece, the seid hub being secured to the head 01 flange 2 by a serew 01 holt 13. The die carrying piece 4 projeets fokwardly through the opening within' the flange 12, a1id this projecting portion is threaded, es ab .5, and the face of this die carrying piece is provided with inserted Specifieation ofI.etters Patent.
dnd byturning'lhiS ga'ge pieee its p'1'a'in' beveled fziee 18 is' adjsted in" respect This co'r'1Sti'ctin netzessitafied separate mit und pin forea ch die seetiqn,end eaeh die er Setion had t be pro'Vided with zin opening foi the pin or bolt, and if there were four dies it required four adjustments, one for each holt or nut, in order 130 elamp the four dies in place. Furthermore, the perforating of the dies 130 receive the pins n0t only increased the cost 0f manufacture, but rendered the dies liable to warp in hardening. In order to avoid this Construction, I employ a elamping nut A, which is threaded on its interior and is fitted t0 the exterior threads B of the gage *ring 19. This nut is provided with a cylindrieal portion a, and an inwardly extending flange er face portion 0 Which overlies the front faces of the dies and securely clamps them in the positions to Whieh they may be adjusted, and this nut also serves to lock the gage ring against displacement 011 the die carrier 4. It Will be observed that by turning this nut A all of the dies Will be clampedab one action, and simultaneously the in place. V
- y present improvement also eoncerns the formation 0f the dies themselves.
In the formation of the sectional die I employ a milling instead of a drilling operation for the gullets 01 radial openings 01 recesses d. A number of the sections can be milled at one operation t0 form these gullets or half circular reeesses, anal where four seotions are employed a gang of eight gage ring W111 be locked milling cutters may be used. The sections, When placed together, provide the recesses er gullets es shown in Fig. 2, which, if drilled in the die block, would have to be done before the block is split. Further by the milling operation the front end of the gullet at d can be milled deeper than ab the rear o1 inner end cf the die section, this providing, when the die sectionsare brought' together, recesses d which flaie toward the front und thus provide f01 the escape of hips am]. prevent tlie die fro1n clogging.
I do not limit myself 130 the particular arrangement of the clamp mit and gage ring described and shown except es called for by t-he appended claims.
I claim 213 my invention:
l. In combination Witl1 the die block sCrew tl1readed externally, a plurality of dies et the front tliereof, a gage ring having an internal thread engaging tl1e external tl1read of the die block, und havii1g a conical inner face to engage the conical outer faces of the sections, and a locking nut engaging an external thread on the gage ring end having a portion engaging the dies to clamp t-he same in place, substantially es described.
2. In combination with a die block having an exterior cylindrical screW-threaded portion, a gage ring having an internal thread engaging the' external thread of tl1e butting portion, seid die block und having 1neans to variably determine tl1e positions of die sections, seid gage ring having an external screw thread, die sections within tl1e gage ring und having their front faces in a plane substantially at right angles to the axis of the gage ring, and a locking nut engaging ehe external screw thread cf the die block end having a flenge extending inwardly et right angles to its axis to bear on the front faces of tl1e die sections, substantially es described.
3. In combination a die block, die sections, a ring portion surrounding die die sections baving means for variably determining tlie positions thereof, and'2i clamping nut screwthreaded upon seid ring portion and having a front flange to bear 011 the faces of the dies for clamping them in position.
4. In combination a die holder and a die c-0mp0sed of sections divided from each other 011 lines parallel with the axis of the die, eachof seid sections having a, outting a gullet et eech side of the gullets being deeper at the front than et the rear of the sections, t-l1e gullets of adjacent sections matching euch other and providing recesses Hering ioward the front of the die, substantially es described.
