Abstract

568,533. Screw propellers. ENGLISH ELECTRIC CO., Ltd., and-SEEWER, P. W. Aug. 21, 1942, No. 11811. Addition to 568,531. [Class 114] [Also in Group XXVI] In an airscrew, marine propeller, hydraulic turbine, or pump rotor, having swivelling blades, in which a hydraulic servomotor in the hub operates a slidable sleeve 6 having inclined channels 6a co-operating with blocks 5 which are pivoted on cranks 1b on the blades, as described in the parent Specification, the slider blocks and the channels are all of cylindrical arcuate form struck about axes parallel to, but not coincident with, the pivotal axes of the cranks so as to reduce the variation in the leverage at which the force is applied to the cranks with variation in the position of the sleeve and cranks.
