In a dishwashing apparatus having a tub defining a wash chamber and having a timer mechanism for controlling operation of the dishwashing apparatus through an operating cycle, a reservoir for containing a supply of washing additive, and dispensing means for selectively closing said reservoir as a result of the dispensing means being disposed in a first position and opening the reservoir to release additive therefrom into the wash chamber as a result of the dispensing means being disposed in a second position, improved structure for connecting between the timer mechanism and dispensing means comprising:

  • a cam follower associated with the timer mechanism and movable in a prescribed path in response to operation of the timer mechanism as the dishwashing apparatus is cycled and residing in a first position at a predetermined stage in an operating cycle;

    an actuating member for connection with the cam follower and movable to change the dispensing means from the first position to the second position;

    means for blocking movement of the actuating member with the actuating member in an intended position of the actuating member at said predetermined stage of an operating cycle; and

    cooperating means on the cam follower and actuating member for adjustably fixing the relative positions of the cam follower and actuating member as the actuating member and cam follower are moved relative to each other,whereby the actuating member can be blocked by the means for blocking movement in the intended position of the actuating member at the predetermined stage of an operating cycle and the timer mechanism can be cycled to move the cam follower to the first position thereof to establish consistent interconnection of the cam follower and actuating member in operative position.
