Abstract

A battery driven toy top containing a motor rotated flywheel enclosed in a domed housing. The top may be spun on either the dome or preferably on the opposite end of the tubular housing and contains noise generators and flashing lights controlled by a novel centrifugal switch.

Claims

1. An electrically rotated toy top comprising:

a tubular first housing;

an electric motor within said first housing, said motor having an extending rotatable shaft coaxial with said tubular first housing;

a battery within said tubular first housing, said battery having a first terminal in contact with a first motor terminal and a second terminal in contact with a second motor terminal through a momentary contact electrical switch;

a rotatable flywheel coupled to said motor shaft, said flywheel including an overlying hollow dome with a small opening therein;

a second housing, said second housing including a second hollow dome closely overlying the hollow dome on said rotatable flywheel, said second hollow dome having a plurality of openings to form first sound generating means upon relative rotation between said hollow domes; and

second sound generating means including a multiple spoked non-rotatable disc centered around the shaft end of said motor and a resilient member coupled to said rotatable flywheel and extending into the spokes of said disc.

2. The toy top claimed in claim 1 wherein the hollow dome on said second housing is formed with a center peak for the spinning of said top on said peak.

3. The toy top claimed in claim 1 wherein said momentary contact switch includes a manually operable pushbutton extending from the surface of said first housing.

4. The toy top claimed in claim 1 further including at least one electrical lamp coupled to said top, said lamp being coupled to said battery through a centrifugal switch closed by the rotation of said first housing.

5. The toy top claimed in claim 4 wherein one lamp is located in the surface of said second housing.

6. The toy top claimed in claim 4 wherein one lamp is coupled to the end of said rotatable motor shaft, the first pole of said lamp being coupled to one battery terminal through a brush commutator coupled to and insulated from said motor shaft, the second pole of said battery being coupled through said motor shaft and motor housing to said centrifugal switch.
