ABSTRACT:
A propeller driven toy comprising a hollow cylindrical elongated fuselage having radially spaced fins mounted thereon, a front propeller rotatably mounted on the forward end of the fuselage and having a circular hub provided with inwardly facing recessed notches along its periphery, four radially spaced blades and a drive shaft extending inwardly through the center of the hub; a rear propeller substantially identical to the front propeller rotatably mounted on the rear end of the fuselage in axial opposition and counter-rotating to the front propeller; a rubber band interconnecting the drive shafts and their respective hubs; a locking mechanism housed internally of the fuselage comprising a wheel rotatably mounted on a horizontal shaft, a lever having its inner end rotatably received on the wheel shaft and interposed between the sides of the wheel and having its outer end free to project outwardly from fuselage, a pair of elongated lock rods in offset axial alignment with the fuselage having their inner ends mounted on the wheel and their outer ends adapted to engage the recessed notches; a spring slidably received on one of the lock rods and adapted to compress when the rods are extended into the notches thus inhibiting the rotation of the propellers; and a catch employed to hold the lever in a position perpendicular position to the fuselage; and wherein turning of the lever from its perpendicular position rotates the wheel to retract the rods out of the notches, thus releasing the propellers.
