Abstract
Abstract A float apparatus for attachment to a conventional bicycle comprising a frame member having horizontally extending distal ends which are connected to laterally spaced pontoon floats. The frame member is acutely angled intermediate the distal ends thereof to obtain a vertically extending loop portion for bridging the front wheel of the bicycle. The upright legs of the loop portion of the frame member carry brackets adapted to connect to the front wheel axle by which means the front portion of the float apparatus is attached to the bicycle. A similarly formed second frame member is provided to support a second pair of pontoon floats laterally spaced apart. A horizontally positioned axle is connected between the second pair of float members and is provided with paddle wheels and a sprocket gear. A sprocket chain connects a sprocket on the rear wheel of the bicycle and the sprocket on the paddle wheel axle and is driven by pedaling the bicycle. A swivelly connected rubber device is clamped to the nadir part of the front wheel and is movably controlled by lines strung to the handlebars.

Claim 1
Independent Claim
121 words
A float apparatus for a bicycle cOmprising: a pair of float means; a bar member connecting said float means in laterally spaced relation; said bar member being acutely angled at the center portion thereof to provide a loop for straddling the forward wheel of said bicycle; bracket members on said bar member connected to the forward wheel axle of said bicycle; a second pair of float means; a second bar member connecting said second float means in laterally spaced relation; said second bar member being acutely angled at the center portion thereof to provide a loop for straddling the rear wheel of said bicycle; and bracket members on said second bar member connected to the rear wheel axle of said bicycle.
Claim 2
Dependent Claim
121 words
A float apparatus for a bicycle cOmprising: a pair of float means; a bar member connecting said float means in laterally spaced relation; said bar member being acutely angled at the center portion thereof to provide a loop for straddling the forward wheel of said bicycle; bracket members on said bar member connected to the forward wheel axle of said bicycle; a second pair of float means; a second bar member connecting said second float means in laterally spaced relation; said second bar member being acutely angled at the center portion thereof to provide a loop for straddling the rear wheel of said bicycle; and bracket members on said second bar member connected to the rear wheel axle of said bicycle.
Claim 3
Dependent Claim
52 words
