Abstract

541,206. Variable-pitch propellers. SUGIMOTO, K., and MORI, E. May 2, 1940, No. 7874. Convention date, May 12, 1939. [Class 114] In automatic variable-pitch propellers in which the airpressure resistance acting on the surface of the variablepitch blades is balanced against the centrifugal force through the medium of spiral springs, the springs are composed of a number of separate spiral strips 6 fixed at one end to a cone member 4 radially mounted on the propeller bar and at the other end to the blade 3 through the mounting 7.
