[Text from Blueprint Image] FREE WHEEL CLUTCH LOW SPEED DRIVE HIGH SPEED DRIVE CENTRIFUGAL CLUTCH NORMALLY HELD OUT BY MANUAL CONTROL UP TO 5000 FT CENTRIFUGAL CLUTCH FITTED AS IN OUR DRIVE Above is a diagrammatic sketch of drive employed. The low speed drive is operated through a free wheel clutch. As soon as the high speed clutch is engaged this gear runs in free wheel. The high speed drive shaft is actually duplicated, the two shafts being at 180 degrees and the gears fitted with centrifugal clutches so that a balanced load is obtained as in our case, and the bearings are saved. | ||
