Reversible wobble drive
Abstract
Abstract FOR IMPARTING WOBBLING MOTION WITH REVERSIBLE PRECESSION TO A RESILIENTLY SUPPORTED TUMBLING VESSEL, A GENERALLY UPRIGHT IMPELLER SHAFT IS JOURNALED IN TWO BEARINGS MECHANICALLY CONNECTED WITH THE VESSEL AT AN UPPER AND A LOWER LEVEL AND IS LINKED WITH THE SHAFT OF A REVERSIBLE DRIVE MOTOR VIA TWO CASCADED UNIVERSAL JOINTS SO AS TO EXERT INDEPENDENT THRUSTS UPON THE VESSEL THROUGH THESE BEARINGS. THE IMPELLER SHAFT IS ECCENTRICALLY LOADED BY TWO WEIGHTS SECURED TO IT NEAR THE TWO BEARINGS, WITH THE UPPER WEIGHT LEADING THE LOWER WEIGHT BY 90* IN THE DIRECTION OF ROTATION. THE UPPER WEIGHT IS MOUNTED ON THE SHAFT THROUGH A LOST-MOTION COUPLING WITH 180* PLAY WHEREBY A REVERSAL OF SHAFT ROTATION CAUSES THIS WEIGHT TO SWING INTO A DIAMETRICALLY OPPOSITE POSITION.
