250,636. Mann, V. Dec. 15, 1924. Regulating.-A wind-motor for utilizing the Magnus effect comprises rotatable cylinders 1, or other figures of revolution, which are radially arranged in a wheel 30, and are rotated by the relative rotation of the wheel 30 and a concentric bevel-wheel 7 gearing with the cylinders 1. To start the motor, the wheel 7 can be rotated through gearing 20 - - 26 from a handle 27 or a motor, when the wheel 30 is revolving, the shaft can be locked by a bolt 29. The wheel 30 drives, a power-shaft 19, which can be made to drive the bevel-wheel 7 to increase the speed of rotation of the cylinders 1 through gearing 38 - - 35, Fig. 3, a clutch 40, shaft 83, variable belt gearing 32, 33, 34, a clutch 82, and the gearing 26 - - 20. In this modification, the handle 27 may be arranged as shown to drive the shaft 83 through a clutch 39. which is linked to the clutch 40 for simultaneous operation. The wind-wheel may be stopped by turning it out of the wind, or by stopping the rotation of the cylinders 1; the latter may be done by rotating the wheel 7 in the same direction as the wheel 30, and if this rotation is effected at a speed greater than that of the wheel 30, a braking-effect is produced. To reverse the rotation of the wheel 7, the clutch 82 is shifted so that the shaft 26 is driven either from the shaft 19 or the starting means through the crossed belt 81. For varying the drive from the shaft 19 the belt 34 may be shifted through a relay from the governor driven from the shaft 19. In one relay, the governor operates a control piston for the admission of pressure fluid to a servo-motor, the piston-rod of which is linkconnected to the belt-shifting lever. In an electric relay, the governor controls the direction of drive, and the speed, of a motor 68, Fig. 10, which operates a screw-and-nut device 69, 70, 61 to move the belt-shifting lever 63. This screw- and nut device may also be used for hand-control. The arms of the wheel are shaped so as to assist in the rotation thereof and are directly behind the cylinders.
