Abstract: A toy timing device including an escapement-like mechanism regulating the movement of a movable portion toward a position on a housing toward which it is biased by the alternate slipping and sticking of parts of a rubber band extending over ribs on the movable portion as the rubber band parts move along a continuous surface on the housing.

Abstract: A toy adapted to be immersed in water and activated by gas generated by wetted baking powder in a cavity within the toy. The toy has a pocket disposed generally above the cavity and the center of gravity of the toy. The pocket is shaped to collect gas from the cavity so that the toy rises in the water and, when the collected gas bubble reaches a sufficient size or the toy reaches the surface of the water, the toy to tip so that the bubble will escape through an orifice at an edge of the pocket which allows the toy to again sink in the water. The cycle will repeat so that the toy repeatedly rises and sinks in the water.

Abstract: A door alarm toy comprising a whistle adapted to be sounded by air escaping from an inflated balloon; and a clip adapted for engagement between a door and its door frame to hang the toy with an inflated balloon pressed against the door to frictionally retain a twist in the balloon which prevents it from deflating. When the door is then opened, the toy drops, the balloon untwists and air escaping from the balloon sounds the whistle.

Abstract: A toy timing device including a rotor which can be manually moved from a stop to a start position on a housing and will move back to a stop position under the influence of biasing means which decreases in biasing force as the rotor moves toward its stop position. The housing has spaced projections which tension a rubber band in adjustable frictional engagement across a friction surface on the rotor. The friction surface on the rotor is generally parallel to its plane of movement except for a portion defined by a rib projecting along one edge of the surface that is shaped so that the frictional engagement of the rubber band on the rotor will decrease as the rotor moves to its stop position to produce rotor movement of a slow and generally constant velocity.

Abstract: A popper toy comprising a dish shaped wall of thin flexible resilient polymeric material. The popper wall has a plurality of concentric portions including outer portions providing a generally rigid support structure, and central portions providing a domed structure adapted to be deflected under moderate thumb pressure. When the domed structure is deflected a portion of its outer surface will temporarily change from convex to concave. The central domed structure will then suddenly recover its original shape a short time after the pressure is released, thereby suddenly returning the portion of its outer surface to convex so that the popper will leap into the air if its outer surface is positioned against a firm surface as the domed structure recovers.

Abstract: A toy including separable base and central portions defining a cavity therebetween and a cover portion pivotably mounted on the central portion. The cover portion has a concave surface positioned over an aperture communicating with the cavity when the cover portion is in a closed position. When a chemical which will produce gas bubbles in the presence of water is placed in the cavity and the toy is dropped into a container of water, the concave surface will trap gas escaping through the aperture under the cover portion until the buoyancy of the gas moves the cover portion to an open position, allowing the accumulated gas to escape.
