## Abstract

An inverted generally saucer-shaped buoyant toy, containing a battery powered motor, driving a paddle wheel-type rotor, generates movement of the toy with respect to the body of water in which it floats.

## Claims

### Claim 1

A floatable toy simulating a space saucer for placement in and movement in water, comprising:
an endless ring body having a planar horizontal bottom surface and an inner peripheral surface normal to its bottom surface;
a hollow housing extending diametrically across and projecting above said body,
said housing having a horizontal bottom wall secured to said inner peripheral surface in upwardly spaced relation with respect to said body bottom surface;
motor means within said housing including a reversible motor having a drive shaft projecting downwardly through said housing bottom wall;
a reversing switch mounted on said housing and having a control button projecting above the upper limit of said housing;
a battery within said housing and operatively connected with said motor through said switch; and,
paddle wheel means axially secured to said drive shaft and loosely received by the inner peripheral surface of said body for moving said toy.

### Claim 2 (depends on 2)

The toy according to claim 2 in which said paddle wheel means comprises:
a disk having a planar central portion and having a plurality of radially extended equally spaced planar fins.

### Claim 3 (depends on 2)

The toy according to claim 2 in which said body is characterized by an upwardly converging perimeter intersecting said inner peripheral surface on opposing sides of said housing, said housing having inclined end walls lying in the plane of the converging body perimeter.
