    Abstract: A velocipede having a front wheel assembly carrying a front wheel and a rear wheel assembly carrying a pair of co-axial rear wheels. The wheel assemblies are pivotally connected approximately midway between the axis of rotation of the front wheel and the axis of rotation of the pair of rear wheels by a pivotal coupling member that is rotatable around an axis that lies in the longitudinal plane of the velocipede at an angle of 20* from the vertical. A spring within the pivotal coupling member limits the relative displacement of the wheel assemblies to 25* on either side of the vehicle''s normal forward position in response to sideways tilting of the front wheel assembly by means of a weight shifting or a leaning motion of the rider of the velocipede.

    Abstract: An animated doll, energizable by a reversible DC motor, selectively animating a stepping motion or a rotational motion with head spotting. The doll includes a rotatable shaft which is movable along its axis of rotation from a neutral position to an upward position in which the shaft engages a crankshaft assembly to cause the doll''s legs to move with respect to the doll''s torso to produce a stepping motion. The rotatable shaft is also movable to a downward position in which the shaft is inhibited from rotating, thereby causing the motor''s housing, which is connected to the doll''s torso, to rotate and to rotate the torso therewith. The doll''s head is coupled to the torso with a torsion spring, which forms part of a head-spotting assembly. The latter is used to inhibit the rotation of the head during a fixed preselected portion of each revolution of the doll''s torso. All the doll''s motions are controlled by a knob extending out of the doll''s head.

    Abstract: A toy sound system, including a reel-sound amplification mechanism apparatus, a toy airplane, a hanger and a soundinducing filament. Movement of the airplane suspended by the hanger from the filament causes a motion to be induced in the filament which in turn induces a movement of a diaphragm thereby amplifying the sound made. The reel apparatus allows the filament to be paid out to any desired length. The reel may then be locked to prevent further payout. Controlling the reel apparatus allows control of the descending airplane since the far end of the filament is connected to an anchor with a flexible connector which allows movement and yet is easy to attach, while providing a bumper against impact of the airplane and the anchor.
