Propeller And Coupling Member
US Patent:
4842483, Jun 27, 1989
Filed:
Nov 4, 1987
Appl. No.:
7/116358
Inventors:
Edwin S. Geary - Fajardo PR
International Classification:
B63H 120
US Classification:
416 93A
Abstract:
Disclosed is a marine propeller for inboard, outboard, or inboard/outboard motors. The propeller is made from a non-metallic composite material that will not deform or deflect even at very high horsepower or RPMs. At the same time, the propeller is substantially less expensive than traditional metallic propellers. An especially unique feature of the propeller is that, unlike metallic propellers, it will shatter when it strikes a solid object in the water, thereby avoiding the engine and drive line damage that occurs when rigid metallic propellers strike a solid object. Also disclosed is a coupling member that permits the propeller to be adapted for use with most inboard/outboard motor configurations.
