Abstract

878,852. Marine propellers. BAMFORD & CO. Ltd., F. March 16, 1960 [March 24, 1959], No. 10250/59. Class 114. A screw propeller has blades 20 pivoted at 21 upon a sleeve 16 which embraces the hub 10 and has a limited freedom of angular movement in relation thereto, the blades in one extreme position of the sleeve, Figs. 1 and 3, being fully locked by abutment of angular root portions 27 thereof with the cylindrical exterior 11 of the hub 10, whereas in the other extreme sleeve position, Figs. 4 and 5, the root portions 27 are presented to flats or recesses 28 in the hub which permit free folding of the blades rearwardly towards the axis of the hub. The freedom of angular movement of the sleeve 16 relative to the hub 10 is limited by at least one radial dog 23, on the forward end of the hub engaging in an angularly-wider recess cut in the corresponding end of the sleeve.
