ABSTRACT:
An improved spring motor in combination with a toy vehicle which can be easily manufactured and which can be wound up by moving the car forwardly and rearwardly in reciprocating movement without changing the physical configuration of the motor. The motor includes a first motor member about which a coil spring is engaged and a second motor member coaxial therewith and motion transmitting means interconnecting the two members such that the first motor member is rotated in response to rotation of the second member in the same direction but at a slightly slower speed. Power take-off means connect the motor to an item to be driven such as the rear wheels of a car. The motor is rewound through the power take-off means during which ratchet means allow the rotational motion transmitting means to be ineffective and during which a rewind ratchet holds the first motor means stationary to achieve high speed spring windup.
