Abstract
A hydrostatic drive is disclosed in combination with a machine tool such as a sand core molding machine. A machine of this type comprises a fixed carriage and a core molding die mounted for rotation on the carriage. The drive includes a reversible fluid power motor having an output shaft. The motor output shaft is connected to a fail safe fluid power brake, and the brake shaft is, in turn, connected to a power transmission unit. When fluid power is applied to the brake and the motor, brake override means operate to release the brake to permit the motor shaft, brake shaft and tranmission to be turned by the motor and thereby operate the movable die.
