Abstract: Coin operated vending machines and vending methods for self service car washes that vend different commodities or services at a united price. The machines vend vacuum at different speeds, and spot remover or fragrance. Each machine has a computer-controlled, multi-segmented bar graph providing an analog indication of the amount of a vend that remains, and a dot matrix system for displaying text messages. The bar graph has multiple adjacent segments each having multiple cells that contain separate LEDS of different colors. The bar graph provides a relative, analog indication of the amount of a particular commodity remaining to be vended. When a vend starts, all of the bar graph segments are illuminated and as vending continues, bar graph segments and individually cells are sequentially decremented. Different products are associated with different colors. The customer may switch selections while a credit balance remains, and bar graph illumination is reset to 100%.

Abstract: A vending machine and a hose controller system for vending machines wherein the dispenser hose is axially and torsionally controlled to facilitate slight twisting, thereby minimizing applicator tool resistance, and making it easier for users to operate the remote vending tool on the hose distal end. The elongated reinforced applicator hose terminates at the controller, which bridges the hose between the outdoors and the cabinet interior. The controller has an angulated bracket mounted within the vending machine cabinet. A collar assembly secured on the bracket top above a hose feed-through orifice has a terminator, a bushing, and a cooperating yoke that are coaxially secured. The terminator anchors the hose end and is seated within the yoke. A rigid lug projects radially from the yoke. A rigid restrictor surmounts the collar assembly and limits rotation by contact with the lug.

Abstract: An electronic alarm and a vending machine equipped with the alarm monitors a plurality of zones by suitable circuitry to detect vandalism and theft. Each zone has a mechanically-triggered sensor that provides an electrical output. The zones comprise a pair of door sensors and a separate, shock sensor. A solid-state logic circuit includes a red and green indicator light, and a loud warning buzzer ultimately triggered by the sensors. A circuit time delay and logic scheme analyzes sensor status, and separate false-alarm prevention circuits insure proper triggering after a predetermined delay. Alarm status is indicated by highly visible green and red status lights mounted on the door. A buzzer sounds in response to sensor activation and circuit logic. A back-up battery that is coupled to the logic circuitry for fail-safe operation includes an automatic recharge system, and dual red and green LED's monitor battery condition.
