LATHE AUXILIARY APPLIANCE.
SPECIFICATION formingpart of Letters Patent No. 704,440, dated July 8, 1902.
Application filed October 25, 1901. Serial No. 79,972. (No model.)
To aZZ whom i may cww 'n: riphery of the collar 15 on the spindle 10 is Be it known that I, SAMUEL HARBORD ORO- graduated to register quarter-turns of the KER, a subject of the King of Great Britain spindle on the nick 16.

The said belt or cord pulley may be that the appliance comprises and is adjustdriven in any suitable manner. Upon the able upon the pillar 1, which rises from the other end of the mandrel may be mounted a 85 tool-box plate 2 of a slide-rest. Such pillar chuck or tool-holder or work-holder or other is adjustably mounted on the said plate-that analogous appliance. is to say, it may be rotated upon the bolt 3, Assuming, then, that the work-namely, passing through the pillar, and be tightened the metal or wood to be machined-is upon by the sleeve-nut 4, the head of the bolt bethe lathe and the tool is carried on the end 90 4o ing held in a slot in the tool-box plate 2, as of the mandrel 27, the pulley28 being driven shown at Fig. l. Capable of sliding upon by the cord or belt aforesaid, it will be unsuch pillar on a feather and keyway Sis a derstood that the construction of the applibracket 9, the movement of the bracket on ance forming the subject of this invention the pillar being effected by the screwed spin-- permits of the work being operated upon at 95 dle 10, which is journaled parallel with the. any point or at any angle or inclination pillar. This spindle threads in a nut 11 on that is to say, in addition to the movements the bracket 9. and is rotated by the handle 12. of the slide-rest the pillar is revoluble there A scale 13 on the pillar coincides with the on. The bracket 9 is capable of vertical pitch of the thread on the spindle 10, which movement on the pillar, and the quill-holder Ice may be sixteen to the inch, and registers with 22, which carries the mandrel 27, is revoluble the knife-edge 14 on the bracket 9. The peon the bracket 9. Used as a work-holder it will be understood that the appliance will hold the work in any position, so that it can be drilled, milled, cut, or operated upon in any direction by a tool carried by the lathe. WVhen the work is held by the mandrel, the pulley 28 may be removed and a graduated indented wheel 29 substituted therefor. A springactuated detent 30, carried by a bracket 31, is arranged to engage the indents of the wheel 29, so that the work may be revolved step by step. The bracket 31 possesses a beveled foot 32, which is socketed in the quill-holder 22 and locked there by the overhang of the nut 33. This nut is cut away at 34 to permit of the removal of the bracket 31. This arrangement can be used in cutting the teeth of a pinion-wheel, the wheel-blank being held on the mandrel 27 while the cutter is carried by the lathe.
The bracket 9 may be capable of free upward movement on the pillar 1 and be normally depressed by the spring 35, (the spindle 10 being removed,) as shown at Fig. 9. A projecting pin 36 on the bracket 9, riding over a former 37 as the tool-boxplate 2 travels backward and forward on the slide-rest 39, causes the tool or work held on the mandrel 27 to move in a curved direction. This movement may be made use of in cutting and backing-0E rose-cutters and like operations.
The capability of universal movement and inclination possessed by the appliance e11- ables it to be used in various cutting and mill ing operations--such, for instance, as cutting and backing-off milling-cutters of all shapes, cutting bevel wheels and miter wheels, crown wheels, cams, gear wheels, wormwheels, slots, either straight or curved, internal and external grinding, and the like.
Having now described the said invention, what I claim as new, and desire to secure by Letters Patent, is
1. In combination, a pillar revoluble upon its base, a screwed rod parallel with and journaled in the cap of said pillar, a bracket bored to receive the pillar and screwed rod and threading with the latter whereby it may be adjusted vertically on the pillar, a face on said bracket and a bevel-groove therein receiving a beveled button on a quill-holder, a quill within said holder, means for adjusting and for locking such parts, a mandrel journaled in the quill, and means for rotating the mandrel, forming a lathe -tool or work holder, as described,
2. In combination, a pillar and a keyway therein, a bracket capable of Vertical movement on said pillar and keyway, a screwed spindle journaled on the pillar and threading a nut on the bracket, by which the latter is moved, a knife-edge, and a scale on the pillar proportionate to the thread on the spindle, means for indicating partial revolutions of the spindle, whereby the bracket movement is graduated, a quill-holder revoluble on said bracket and containing a quill, and a rotating mandrel journaled axially in said quill, forming a lathe-tool or work holder, as described.
3. In combination, a revoluble pillar supporting an axially-adjustable bracket, a face on said bracket parallel with the axis of the pillar, a bevel-groove in said face with a semicircular finish, receiving a beveled button on a quill-holder, a follower in said groove completing a socket for said button, a stud for tightening the follower on the button where by the quill-holder is revoluble on and may be locked to said bracket, a quill in said holder and a rotating mandrel in the quill, forming a lathe-tool'or work holder, as described.
at. In combination, a quill-holder revoluble on a bracket adjustably supported on a revoluble pillar, a quill held rigidly therein, and a mandrel journaled in the quill with projecting extremities carrying an implement and an index-wheel respectively, and a detent carried by a bracket on said quillholder, said detent controlling the rotation of the mandrel and implement by engaging the index-wheel, forming a lathe-tool or workholder, as described.
5. In combination, a quill-holder revoluble on a bracket adjustably supported on a revoluble pillar, a quill in said holder and a mandrel in said quill, an index-Wheel on the mandrel engaged by a detent carried by a bracket, a beveled slot in said holder receiving the said detent-bracket and a lock-nut on said quill-holder for retaining said bracket in its socket, forming a lathe-tool or work holder, as described.
