Drive mechanism suitable for a parts treating machine comprises a housing defining a chamber containing a rotatable carriage wheel with a fixture journalled for rotation thereon. A carriage wheel drive is provided for indexing the carriage wheel and a fixture drive for rotating fixtures carried by the carriage wheel at a predetermined position. The carriage wheel drive includes a motor and a gear reducer operatively connected to the carriage wheel. The fixture drive includes a motor and a gear reducer operatively connected to a gear on a shaft extending upwardly from the fixture by an endless belt. The carriage wheel may be moved from a load station to a treating station, where spray nozzles or the like may spray treating material onto the parts to be treated as they are rotated together with the fixture at the treating station. Thereafter, the carriage wheel is indexed to move the fixture to an optional blow-off station, where blow-off nozzles can blow air against the parts to remove treating material and to dry the treated parts, and subsequently to return the fixture to a load station where the treated parts can be removed from the fixture and parts to be treated can be placed into the fixture to begin the next cycle of operation. The carriage wheel and the fixture can be driven either by a single motor or by separate motors, as desired.
