Shave tool holder having a floating body incorporating a tapered dovetail and adjustable gib and including interchangeable tool posts

A shave tool holder for use with an automatic screw machine and for machining a rotatably driven workpiece, said tool holder comprising:

• a shank engageable with the screw machine and for providing reciprocating motion of the shave tool holder, said shank further comprising a forward mounting portion within which is formed a dovetail shaped slot;
• a body having a rearward mounting portion upon which is formed a dovetail shaped projection received within said slot;
• a recess defined within said forward mounting portion of said shank, in proximity to said dovetail slot and a bottom edge of said mounting portion, an interiorly threaded aperture being defined within said shank mounting portion and communicating with said recess, a collar portion projecting from a forwardly facing surface of said dovetail shaped projection and which is received within said slot over a limited axial range upon mounting said body to said shank;
• a coil spring seating within said recess and abutting against said collar portion, a bolt threadably engaging through said collar portion, coil spring and interiorly threaded aperture for mounting said body to said shank in a vertically deflectable and adjustable manner;
• a roller secured in vertically adjustable fashion to a forward facing location of said body;
• and
• a tool post releasably secured to said body, a cutting insert being secured upon said tool post in a desired spaced relationship relative to said roller and so that the rotatably driven workpiece is adapted to being received between said roller and said insert.
