Abstract

430,472. Friction clutches. STRUCK, W., 3, Liliencrostrasse, Steglitz, Berlin. Dec. 12, 1934, No. 35715. Convention date, Dec. 14, 1933. [Class 80 (ii)] [See also Group XXXIII] Screw propellers 1 and 2 are secured to discs 5, 6 and 7, 8, mounted on the hollow shaft 3 so as to be free thereon. Keyed to the shaft are blocks 16, 17 having stops 20 against which one end of the helical spring 18 or 19 abuts. The other end is adapted to bear against the inclined end of a stop 22 or 23 and these are raised or lowered by means of a rod 4 slidable in shaft 3 and having a cam groove 24. In the position shown, the spring 18 is frictionally gripping the block 16 and the propeller 1 is being rotated whilst the propeller 2 is free since the spring 19 is held up by the stop 23 free from the corresponding block 17.
