Swimming device

A swimming device, comprising in combination, a frame supported at its forward end on a waist belt, shoulder straps extending from the waist belt, a crankshaft rotatably positioned transverse to the frame, foot pedals located at opposing ends of the crankshaft, a first gear fixed onto said crankshaft and having a plurality of radially different speed controlling sections thereon, with the slower speed control section being radially inward of the faster control section, a propeller shaft extending from the rear end of said frame, a propeller fixed at the distal end to said propeller shaft, a second gear fixed at the medial end of said propeller shaft and engaging said first gear, a housing supported by said frame for protectively surrounding said propeller, biasing means for normally biasing said second gear to engage said first gear at the outermost speed control section thereof, said shaft, second gear and propeller being slidable together relative to said frame and housing in the direction of the shaft's axis, a collar formed on said propeller shaft, a hand operated rotatable winch formed on said waist belt, a cable extending from said winch and coupled to said collar, whereby the operator of said winch selectively moves the second gear against the bias to engage slower speed control sections of the first gear by winding said cable about said winch, said winch being constructed and arranged to maintain said second gear in a selected position without further restraint by the operator.
