  • Patent number: 5907958
    Abstract: A water filter assembly mounted to an inner surface of a refrigerator and accessible from within a refrigeration compartment of the refrigerator. The filter assembly includes a first housing part, a second housing part, and a replaceable filter cartridge. The first and second housing parts cooperate to define a fluid-tight chamber for receipt of the filter cartridge. The first housing part includes an inlet port through which unfiltered water may be introduced into the chamber and an outlet port through which filtered water may exit the chamber. The second housing part surrounds a portion of the first housing part and provides a volume sufficient to hold the filter cartridge and any water within the chamber when the second housing part is released from the first housing part to replace the filter cartridge, and thereby prevents or minimizes spillage of water from the filter assembly during filter cartridge replacement.

  • Patent number: 5711288
    Abstract: A spice rack for a cooking range including a one piece shelf defining an elongated channel for receipt of spice containers. The spice rack includes a front panel and a rear panel, the rear panel having barrier members extending therefrom generally toward the front panel which separate the elongated channel into a series of smaller spaces for segregation of spice containers. The rear panel has a flange member extending therefrom which cooperates with the rear panel to define a channel for receipt of a mounting bracket. The mounting bracket is secured to a rear wall of the cooking range and vertically supports the spice rack and spaces the spice rack from heat producing portions of the cooking range. The spice rack also includes lateral flanges that serve as stops to limit lateral movement of the spice rack relative to the mounting bracket.
