Propeller Drive And Steering Mechanism For Small Craft
US Patent:
5282762, Feb 1, 1994
Filed:
Aug 8, 1991
Appl. No.:
7/742307
Inventors:
John Cerreto - Wrentham MA
International Classification:
B63H 1620
US Classification:
440 30
Abstract:
A portable propeller drive and steering mechanism for small craft in which a frame is provided with an adjustable seat and a pedal driven chain drive connected to a geared transmission, and which has a chain drive output powering a horizontally arranged jack shaft. The jack shaft is provided with a universal gearbox whose output in turn powers a propeller. A steering handle located adjacent the seat is provided with steering linkage connected to a propeller drive shaft housing which carries the propeller at one end and is rotatably mounted within the gearbox at its other end. Operation of the linkage causes rotation of the propeller drive shaft housing. Raising and lowering of the handle will cause motion between a pair of gears in the gearbox and rotation of the propeller drive shaft housing around the axis of the jack shaft to vertically raise and lower the propeller.
