Abstract
A tool holder assembly mountable on a lathe housing for dressing cylindrical and flat walls of drums and disc shaped work pieces respectively, has a mounting plate formed with two mutually perpendicular walls each carrying a short drive shaft. The assembly may be disposed in one position with one wall at the lathe housing so that one shaft is driven by a lathe motor in dressing a drum. The assembly may be disposed in another position with the other wall at the lathe housing so that the other shaft is driven by the lathe motor in dressing a disc.

A tool holder assembly for dressing walls of cylindrical and flat disc shaped work pieces in a lathe having support means for rotatably supporting a work piece to be dressed, and motor means operatively arranged to rotate said work piece on an axis extending outwardly of said support means, comprising:
- plate means mountable on said support means in different positions;
- shaft means rotatably carried by said plate means and drivable by said motor means;
- a mounting plate for holding a dressing tool;
- slide means slidably carrying said mounting plate and secured to said plate means;
- a lead screw rotatably engaged with said mounting plate to move the same along said slide means;
- coupling clutch means operatively connecting said shaft means to said lead screw for rotating the same;
- and
- attachment means for mounting said plate means on said support means in a first one of said positions such that said mounting plate moves toward and away from said support means whereby said dressing tool moves axially of said work piece, and for mounting said plate means on said support means in a second one of said positions such that said mounting plate moves parallel to said support means whereby said dressing tool moves radially of said work piece.
