ABSTRACT:
A dishwashing apparatus having a wash chamber, a timer, an additive reservoir and a dispenser for selectively closing and opening the reservoir. The improvement is a follower for moving in a prescribed path as the timer mechanism is cycled an actuating member consisting of first and second relatively movable parts connected to the follower and dispenser and causing the dispenser to move from its closed to its open state as the timer operates during one portion of a cycle and movement of the actuating member in a first path portion in a first direction and for causing the dispenser to move in a second path portion that substantially retraces the first path portion in a direction opposite to the first direction during another portion of an operating cycle, structure for biasably holding the actuating member parts together in operative position and for permitting one actuating member part to be moved relative to the other against a force imparted by the holding structure to a separated position as the one actuating member part is moved in one of the first and second path portions, structure for blocking movement of the one actuating member part in the one path portion, and cooperating structure on the one actuating member part and follower to permit adjustable fixing of the relative positions of the follower and one actuating member part as the one actuating member part is blocked moving in the second path portion and the follower is moved during a cycle.
