摘要 |
A toy boat powered by a rubber-band as a source of driving power for a propeller, the rubber band being wound to energize it by a helical type spiral rod adapted to be reciprocated longitudinally within the hull of the boat respectively in opposite directions to wind the rubber band by means of a gear train actuated by the spiral rod when moved in one longitudinal direction and clutch structures being included to permit sequential retraction of the spiral rod while the rubber band is prevented from unwinding during such retraction without the use of a locking member or the like.
