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.
