An apparatus for moistening adhesive coatings on postage material and the like, comprising:
- (a) an enclosure member;
- (b) an open top liquid container disposed within said enclosure member;
- (c) a spring biased linkage member pivotally mounted within the enclosure member and biased to a predetermined position;
- (d) a moistening member pivotally mounted to the linkage member, said moistening member being movable from a first position in which it is disposed within the open top liquid container to a second position in which it is extended outwardly from the enclosure member;
- (e) a plunger reciprocally movable within the enclosure member, said plunger engaging the linkage member for applying a force thereto non-coincident with the linkage member's pivotal axis to overcome its spring bias;
- and
- (f) a reciprocally movable closure member, said closure member being movable from a first position to a second position in response to a force transmitted by said moistening member for selectively closing and exposing of an opening in said enclosure member, said moistening member extending through said opening when said closure member is in its second position.
