Abstract
Abstract The present invention is a toy simulating a circus seal. A flipper is mounted for movement at one end of the casing which is configured as the seal while a moving wheel is positioned adjacent the seal''s mouth. A conduit passes downwardly from the seal''s mouth to a pump located within the bottom of the casing. A miniature electric motor powered by batteries is located within the bottom of the casing and is operatively connected to a gear train which sequentially drives the flipper propelling the seal and operates the pump propelling water through the seals''s mouth to turn the wheel.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
275 words
A toy, comprising: a casing; first and second bodies, means connecting said bodies to said casing permitting movement of said bodies relative to said casing; a motor, means operatively mounting said motor within said casing; and a gear train mounted within said casing, means operatively connecting said gear train to said motor, said gear train further comprising first and second shafts operably connected to said first and second bodies, respectively, and means sequentially turning said first and second shafts so as to sequentially operate said first and second bodies comprising a first gear fixedly mounted to said first shaft, a second gear mounted for rotation about said second shaft, a third gear mounted for rotation about said second shaft, said second shaft being provided with a key formed therein between said second and third gears, said third gear including a cut-out portion corresponding to said key and a cam surface extending therefrom, said second gear including a cam surface complementary with said cam surface of said third gear, said third gear mounted to move on said shaft between a first position wherein said third gear meshes with said first gear and a second position wherein said cam surfaces of said second and third gears mesh and said cut-out portion is fitted over said key causing said second shaft to rotate and a fourth gear, means driving said fourth gear by said motor, said fourth gear meshing with and driving said second and third gears simultaneously, and means rotating one of said second and third gears faster than the other to cause said cam surfaces to move said third gear between said first and second positions.
Claim 2
Dependent Claim
275 words
A toy, comprising: a casing; first and second bodies, means connecting said bodies to said casing permitting movement of said bodies relative to said casing; a motor, means operatively mounting said motor within said casing; and a gear train mounted within said casing, means operatively connecting said gear train to said motor, said gear train further comprising first and second shafts operably connected to said first and second bodies, respectively, and means sequentially turning said first and second shafts so as to sequentially operate said first and second bodies comprising a first gear fixedly mounted to said first shaft, a second gear mounted for rotation about said second shaft, a third gear mounted for rotation about said second shaft, said second shaft being provided with a key formed therein between said second and third gears, said third gear including a cut-out portion corresponding to said key and a cam surface extending therefrom, said second gear including a cam surface complementary with said cam surface of said third gear, said third gear mounted to move on said shaft between a first position wherein said third gear meshes with said first gear and a second position wherein said cam surfaces of said second and third gears mesh and said cut-out portion is fitted over said key causing said second shaft to rotate and a fourth gear, means driving said fourth gear by said motor, said fourth gear meshing with and driving said second and third gears simultaneously, and means rotating one of said second and third gears faster than the other to cause said cam surfaces to move said third gear between said first and second positions.
Claim 3
Dependent Claim
39 words
A toy as in claim 1, said means rotating one of said second and third gears faster than the other comprising one of said second and third gears being provided with a smaller number of teeth than the other.
Claim 4
Dependent Claim
47 words
A toy as in claim 2, said second body being a piston, a cylinder provided with an inlet port through which water may enter and an outlet port through which water may leave and means operatively mounting said piston for movement in and out of said cylinder.
Claim 5
Dependent Claim
50 words
A toy as in claim 3, including a conduit leAding from said outlet port to and through the top of said casing, together with a wheel mounted for rotation on said casing in the path of water emitted from said conduit such that said wheel is turned by the water.
Claim 6
Dependent Claim
30 words
A toy as in claim 3, said first body being a flipper mounted at one end of said casing to move up and down to propell said toy through water.
