  • Patent number: 5486288
    Abstract: A filter assembly adapted for connection between fluid supply and delivery lines to filter fluid flowing therethrough includes a replaceable filter cartridge having at one end concentric entrance and exit passages confined within an axially outwardly projecting annular wall and a mounting head having inlet and outlet ports adapted for substantially fixed connection to the supply and delivery lines, respectively. The mounting head has a cylindrical recess for sealingly receiving the annular wall of the filter cartridge therein, and the filter cartridge and the mounting head each have complementary interfitting ears and lugs thereon for permitting quick locked connection and unlocked disconnection of the filter cartridge to and from the mounting head incident to axial rotation of the filter cartridge in opposite directions, respectively, relative to the mounting head.

  • Patent number: 4277002
    Abstract: An ice dispensing mechanism for use with an ice dispensing machine having an ice storage area and a transfer path for communicating ice from the storage area to the dispensing mechanism; the dispensing mechanism includes first and second enclosures which are arranged subjacent the ice storage area, the first enclosure being adapted to receive ice from the ice storage area, and the second ice enclosure being adapted to receive ice in metered quantities from the first enclosure and move from a position arranged generally vertically below the first enclosure to a second position disposed laterally therefrom wherein the ice within the second enclosure may drop downwardly under the influence of gravity into a suitable ice receptacle or the like.

  • Patent number: 4254896
    Abstract: An ice dispensing machine including an ice storage bin having a rotatable ice agitating mechanism disposed internally thereof and adapted to move ice within the bin toward a discharge opening located in the bottom wall of the bin; an ice discharge chute is disposed below the opening and includes a wall portion inclined upwardly in the direction of rotation of the ice within the bin to prevent ice jamming between the agitating mechanism and the periphery of the discharge opening; a sink assembly is arranged below the ice dispensing area of the machine and includes a sink that is removably mounted so that it may be conveniently detached for inspection, cleaning and the like without requiring disconnection from associated drain conduits and the like.
