Abstract: A normally closed drain valve is substituted for the normal drain plug in a conventional automobile crank case. Rather than remove the normally provided drain plug each time the oil is to be drained, it is only necessary to open the drain valve. Opening of this valve is accomplished by a specially designed coupler connected to a plastic bag. The arrangement is such that when the coupler is urged over the drain valve and twisted, the valve automatically opens to fill the bag with oil. The coupler can then be twisted back to its original position to close the drain valve and removed with the bag containing the oil. The entire operation can be accomplished only using one hand and with substantially no risk of oil spilling or soiling the operator.

Abstract: An animated doll configured in the form of a ballerina having a crown on the head thereof connected to an actuating member on the longitudinal center line of the doll, the other end of the member having a cam. One leg can be detented to a fixed position in vertical alignment with the torso of the doll with the other leg thereof being pivotally coupled to the torso with a crank affixed thereto for co-acting with the cam for causing the leg to kick. The actuating member has a square shaft portion engaging a mating aperture within a drive gear which is driven by a motor fixedly coupled within the torso. Upon holding the crown, the doll rotates and one leg can be pivoted by depressing the crown.

Abstract: A captive flying toy airplane is tethered to a boom pivotally mounted to a turntable for pivoting the boom for altitude adjustment of a toy airplane, the turntable being mounted to a pylon base housing containing drive gears therein. A control housing is provided to position first and second wire control members passing through a tube connected to the housing, one controller of the control housing varying the position of a slide wire rheostat to control the speed of the toy airplane, the second controller pivoting a bell crank through a vertical plane to control the position of an altitude control rod passing through the center of the turntable to effect pivoting of the boom. A sound cone mounted within the pylon has the apex portion engaging a circumferential ratchet surface on one of the drive gears for emitting a simulated motor sound proportional to the speed of rotation of the gear.

Abstract: A two-speed inertia motor having a pair of wheels secured to a common axis, one of the wheels being a drive wheel and having a gear portion coaxial therewith for selectively coupling to an inertia wheel through a first or second gear member for providing two-speed ratios between the rotation of the drive wheel and the inertia wheel. A main gear member is coupled to the drive wheel, the main gear member having a splined shaft portion for slidably receiving a clutch member for concurrent rotation therewith, the first and second gear members being freely rotatable on either side of said clutch member. Means are provided for shifting the clutch member into locking engagement with either the first gear member or the second gear member to secure the so-locked gear member into direct coupling relation between the drive wheel and the inertia wheel.
