ABSTRACT:
A water activity toy has a channel for a stream of water which floats a vessel on the stream, and a paddle wheel that moves through the channel to generate the stream. The paddle wheel includes a plurality of blades on axle stubs which are removably mounted on mountings at opposite sides of the channel. A crank used to rotate the paddle wheel is connected with one axle stub which is liftable out of its mounting. Lifting the crank tilts the paddle wheel to provide clearance for a tall vessel floating by the paddle wheel mountings. The mountings have similar constructions and are oppositely facing. Each mounting includes a horizontal open ended bearing slot having a side slot with a constriction at the outboard end of the slot. Each axle stub includes parallel flattened surfaces which form a reduced dimension region that enables the axle stub to pass radially through the constriction, provided that radial protrusions on the flattened surfaces are out of alignment with the constriction. Otherwise this axle stub must be tilted and withdrawn through the inner open end of the bearing slot.
