    摘要： A manually indexable turret tool post assembly mounted on a lathe or analogous machine compound by means of a rugged supporting column on which is rotatably mounted a turret body supporting a plurality of tools for selective operation on a workpiece in the lathe. The turret is clamped in one of a plurality of predetermined indexed positions by a rotary clamping head cooperating with a coupling member, each provided with circumferentially spaced projections alternating with recesses. The coupling member, with alternating bearing segments and indentations, is seated within the upper portion of said turret body for relative rotation therewith and is mounted nonrotatably on said column, although it is adapted for incremental radial adjustment thereon. Gradually sloping faces on camming lugs on the rotary clamping head cooperate with similar faces between said indentations and bearing segments to effect a downward movement of the coupling member and turret against the base of the column, and to clamp it in its indexed position by the final rotation of the clamping head on the upper end of the column, which is provided with relatively coarse threads having a fast lead. The turret is released from its clamped position by a reverse rotation of the clamping head for a limited extent, which effects the disengagement of the camming lugs from the bearing segments to permit a lifting of the turret body by spring action. An adjustable plunger in the clamping head cooperating with a milled keyway in the coupling member restricts the relative rotary movement between these units within proper limits.

    摘要： A TOOLPOST ADAPTED TO BE AFFIXED TO A LATHE OR SIMILAR MACHINE, AND EMBODYING A CLAMPING MECHANISM THEREIN FOR QUICKLY ATTACHING AND DETACHING A TOOLHOLDER RELATIVE THERETO, AT A PREDETERMINED LEVEL, THROUGH THE INTERMEDIARY OF VERTICALLY DISPOSED COMPLEMENTARY DOVETAILSHAPED FITTINGS ON THE TOOLHOLDER AND ON AT LEAST ONE FACE OF THE TOOLPOST, THE LATTER OF WHICH INCLUDES A HORIZONTALLY MOVABLE CLAMPING MEMBER SHAPED ESSENTIALLY AS A SURFACE OF REVOLUTION. IN THE ILLUSTRATED EMBODIMENT OF THE INVENTION, THE LATTER COMPRISES A DISK-SHAPED OUTER PORTION, TRUNCATED ALONG A VERTICAL CHORD, AND A SUITABLY RECESSED CYLINDRICAL INNER PORTION, THE RAPID AND SIMPLE MOVEMENT OF WHICH, IN A TO-AND-FRO DIRECTION, CONTROLS THE CLAMPING AND RELEASING EFFECTS ON THE TOOLHOLDER.
