Abstract
777,908. Variable pitch propellers. NAAMLOOZE VENNOOTSCHAP KONINKLIJKE MAATSCHAPPIJ DE SCHELDE. Nov. 1, 1955 [Nov. 13, 1954], No. 31245/55. Class 114. In a variable pitch marine propeller in which pitch variation is effected by a rod 3 adapted to move in a bore in the propeller shaft, the propeller boss and the bore being filled with oil and change of volume of the free space therein caused by movements of the rod being compensated, the adjusting rod or an extension 4 thereon passes through an opening 5 in the rear wall 1 of the boss and is sealed in relation thereto by a concentric bellows 6 having an average operative cross section equal to that of the rod or extension where it enters the boss chamber. Rings 7 limit the expansion of the bellows and a perforated sleeve 8 prevents collapse, the extension 4, bellows 6 and sleeve 8 being secured together by an end plate 9. Specification 208,434 [Class 114] is referred to.
