  • Patent number: 6821181
    Abstract: An amusement device with sparking means comprises a central housing which encapsulates a power means. An axle support is located at a bottom portion of the housing, functioning to allow an axle to extend horizontally therethrough. A plurality of wheels are rigidly affixed to the axle and located at extreme ends of the axle. The axle is of a generally bent configuration, functioning to allow the amusement device to move across a surface in a wave-like pattern. A rudder member acting as front support means comes in contact with a flat surface upon which the amusement device is placed, and is rigidly affixed to a wind-up handle. The wind-up handle is rigidly connected to the power means located within the housing, functioning to allow a user to crank the handle to engage the power. A generally elliptical friction disc member is located at a position above the housing and positioned horizontally thereto. The friction disc member comprises a rotating arm, which is parallel to the friction disc.
