Abstract

352,811. Wind motors. NÍLTING, C. and EICHSTAEDT, E., Gumbinner Chaussee, Insterburg, Germany. Sept. 18, 1930, No. 27882. [Class 110 (iii).] The aerofoil-shaped vanes of a wind motor are made in two parts one of which moves radially under centrifugal action at excessive speed, turns at right-angles to its original path, and moves the second, larger portion with it. The two vane parts e, d, are rotatable on a hollow spar c, and the outer part e slides radially outwards under too high a speed of rotation, and turns at right-angles due to a pin sliding in a cam groove f. Pins h connect the vane parts so that they turn together. The hollow motor shaft b contains a rod p which moves upward when the vane part e moves outward, due to the connecting bell crank l and rod k. A weight t on a rope s attached to a sliding block q normally holds the vane parts d, e together. A lever v which bears on a pin u on the block q is used for stopping purposes, by means of a rope w attached to a winch or the like. In a modified arrangement the inner portion d slides radially, and the outer part e rotates only, under action of the connecting pins h. A sleeve, shaped like the vane, covers the gap between the vane parts and slides with the inner vane member d. The shaft b is prevented from rotating in the opposite direction by a locking device such as a pawl-and-ratchet gear.
