  • Patent number: 6003727
    Abstract: A coin operated fragrance dispensing device comprises a casing having a plurality of actuation assemblies for dispensing a predetermined quantity of a user selected fragrance from a plurality of fragrance canisters therein. A lockable front door of the casing presents indicia and selection buttons corresponding to the fragrance canisters therein. The casing includes an adjustable holder adapted to carry variously sized fragrance canisters. A coin inserted through a slot in the front door of the casing falls upon a crank arm and is lodged between flanges thereon. The weight of the coin causes the arm to tilt and thus to pull down upon a pivot arm. As the shaft pivots about an axis established by a shaft which connects the pivot arms of each actuation assembly, push rods extend to move levers into open or unlocked positions. Accordingly, an actuation bar attached to a fragrance selection button is free to slidably engage a pressure responsive valve means of a fragrance canister.
