Abstract

707,620. Wind motors. FORSMAN, E. E. Feb. 6. 1952, No. 3104/52. Class 110(3) The blade of a wind motor comprises a, number of segments 1a, 1d, Fig. 1, each consisting of transverse ribs 13b, Fig 2, inter-connected to form a framework covered with sheet metal or canvas, the ribs being provided with aligned holes a through which passes the supporting spar 2, and interengaging means on the spar and segments to impart a twist to the latter and to retain them in place. As shown in Fig. 2 the holes are provided with diametral slots pitched at an angle varying from end to end. These slots are engaged by ribs 20, Fig. 8, on the spar. Alternatively the slots in the ribs are all in the same plane and the ribs 20 are of helical form. The holes d in the end ribs of a segment are bushed and soft packing is arranged between the flanges of bushes in adjacent segments to make the segments watertight. the pressing together of the segments being effected by nuts and washers threaded on the ends of the spar. Adjustable wedges passing through rectangular holes in the ribs 20 transmit centripetal force induced in the wing segments to the spar. The spar may be reinforced by longitudinal strips 28 and transverse plates 31, one or more of the strips being welded to the plates. The spars are dipped in molten zinc. The spars may be corrugated in which case the ribs 20 are unnecessary and the holes a in the ribs are shaped to conform with the corrugations. The spar may be filled completely with light porous material.
