Abstract: A fragrance dispensing machine for full service car wash installations administers a carefully controlled amount of fragrance concentrate to precisely scent customer vehicles. The machine is preferably mounted upon a wall adjacent the car wash lane for convenient access vehicles being washed. An associated hand-operated applicator gun interconnected with the machine administers a uniform dose of fragrance concentrate during each application, which is outputted as a fine mist. The machine cabinet provides storage space for bottles of fragrance concentrate. An external source of air pressure is applied to the cabinet for generating the mist. An elongated conduit interconnects the applicator gun and the machine and separate conductive tubes within the gun conduit individually transmit air and fragrance concentrates to an atomizer manifold disposed within the applicator gun. Mixing of air and fragrance concentrate is performed within the atomizer through vacuum venturi suction.

Abstract: A dry foaming coin operated carpet and upholstery cleaning machine for a car washes. A rigid, generally box-like cabinet is secured in a convenient user accessible position. An elongated hose extending from the housing terminates in a user-activated brush which outputs foam and facilitates vigorous cleaning. The control circuit comprises a conventional coin mechanism which operates a timer to initiate a vend. The timer first activates an air compressor, which supplies high pressure air to the system. A remote user switch associated with the brush must be activated to thereafter activate a pump to supply cleaning solution, and to close an air solenoid for air mixing. Simultaneously a heater is activated to heat the control block disposed within the brush. A brush control block properly mixes air and cleaning solution. An elongated heater compartment preheats incoming air, which is thereafter mixed with cleaning solution and discharged through a foam generating chamber in the block.
