  • Patent number: 5054654
    Abstract: An apparatus for dispensing both ice and chilled beverages, and more particularly an improved chilled beverage dispenser which has large ice storage capacity and which incorporates an improved system of dispensing ice. The improved ice storage and dispensing system utilizes a circular rotating tray and an intermediate cone chute to dispense ice efficiently in combination with chilled beverage dispensing and maximizes all available space that can possibly be used to store ice within an enclosure.

  • Patent number: 4982058
    Abstract: An improved safety interlock switch device incorporated onto a machine with internal moving components. The device is mounted adjacent a cover which shields the internal components of the machine when the cover is in a closed position. When the cover breaks contact with the switch, electrical circuit controlling the internal moving components is broken such that movement ceases in the interior of the machine. This type of system protects operators who can be injured by moving internal components while also preventing destruction of the internal components caused by contact with external elements while still in motion. The present invention lengthens the time delay between the break in contact of the cover and the deactivation of the electrical circuit controlling power to the internal movable components.

  • Patent number: 4916910
    Abstract: A beverage dispenser of the post mix type having evaporator coils configured in a particular manner to form a slab of ice within a cooling chamber, the formation of which slab of ice is controlled by a thermostat so that a vertically oriented passage is formed in the center of the slab to allow the rotation of an impeller shaft. With the cooling chamber and a passage for connecting with dispenser valves being insulated beneath and beside the compressor and other heat generating components of the cooling unit, the impeller is thus able to operate beneath the ice slab to circulate cooled water around beverage conduits that are layered in a compact configuration, the overall arrangement of the beverage dispenser being compact and resulting in a easily serviceable beverage dispenser having a low profile while also providing a relatively large ice bank and enabling optimum heat exchange between the beverage conduits and the slab of ice without causing freezing of the beverages.

  • Patent number: 4890642
    Abstract: A disconnect for coupling a postmix dispenser juice concentrate line to a bag valve of a juice concentrate bag-in-box container. The disconnect includes an open passageway therethrough with no areas or elements therein that can trap concentrate with pulp. The disconnect includes a hollow body with a juice concentrate passageway therethrough, a stationary poppet valve therein, a movable sleeve with a valve seat, and a spring biasing the sleeve into contact with the valve to close the passageway. The spring is located adjacent the outside of the sleeve to keep the spring out of the passageway.

  • Patent number: 4862918
    Abstract: A valved fluid connection apparatus is disclosed. When mounted within an opening of a fluid container, the apparatus seals the fluid inside the container until an actuating barrel is inserted to open a valve which allows fluid to exit from the container. The apparatus is particularly suitable for use in flexible bags containing fluid juice with high pulp content as a fluid pathway with wide clearances is established when the valve is opened.

  • Patent number: 4732297
    Abstract: A liquid concentrate dispensing apparatus having a removable and refillable concentrate tank with sensors connected therewith flush with the inside wall of the tank to facilitate cleaning. The sensors comprise detectors which include an electrically conductive housing, one wall of the housing is substantially flush with the inside wall of the tank. Spring biased detent members on the outside of the tank releasably connect the detectors with the dispensing apparatus when the tank is inserted to a preselected position. The tank is provided with two such sensors, one is located in the sidewall and the other is located in the bottom wall. When the tank is inserted into the dispensing apparatus, the spring biased detent members engage contacts on the apparatus. A current passes between the detectors on the sidewall and bottom wall when both are covered by liquid concentrate.
