Abstract
458,001. Screw propellers. DOBOS, I., 3, Manyoki ut, Budapest. March 17, 1936, No. 8042. Convention date, Dec. 7, 1935. [A Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 24, 1936.] [Class 114] A variable-pitch airscrew wherein the blades are attached to sleeves rotatably mounted in sockets in a two-part hub, such sleeves have cam projections extending longitudinally with respect to the propeller axis which are engaged by a longitudinal sliding member for pitch adjustment. The parts b<1>, b<2> are bolted together and within the complete sockets then formed threaded sleeves k are freely mounted on ball bearings. The blades are screwed into the sleeves and held by wedges x, y. The inner ends of the sleeves have cams m. Surfaces m1, m2 thereof contacting with inclined surfaces n1, n2 of a displaceable slide consisting of two parts n<1>, n<11>, which are coupled by bolts o that also pass to the adjusting rings. The end of the parts n2 are connected to a disc u which is under the influence of a spring z. The correct adjustment of the apparatus is obtained by using a distance piece p between the surfaces n<1>, n<11>.
