Abstract

1,057,713. Preventing fouling of propellers. G. B. POWELL, A. N. HORN, and B. F. ORPWOOD. Sept. 9, 1965 [June 12, 1964], No. 24573/64. Heading B7V. Apparatus to counteract fouling of a motordriven propeller by weed comprises a knife driven by the motor and a fin mounted forward of the propeller to deflect weed away from the propeller, the knife and fin co-operating to cut weed which has become entangled in the path of the propeller. In Figs. 1 and 2 (not shown) horizontal fins 9 have slots 12 in which the knife 12 (secured to the propeller blade 2 in Fig. 1 and to the propeller shaft in Fig. 2) moves. In Fig. 4 (not shown) the knife 12 is mounted parallel to the fin 9 (which is in a vertical plane) and is reciprocated from the motor 18 by a power takeoff from the forward end of the propeller shaft.
