  • Patent number: 5084172
    Abstract: A filter and bracket apparatus includes a filter element (8) mounted in a filter container (10) on a base (40). The filter base is supported in one of two operating positions by a bracket (100) which has two extending fingers (102) each having a pair of prongs (108, 110) thereon. The filter base has a pair of extending ears (44) which interact with the bracket's prongs to support the filter alternatively in an upright or an inverted position. The invention also relates to a method for changing an oil filter without disconnecting the fluid conduits delivering fluid to and receiving fluid from the filter.

  • Patent number: 4869820
    Abstract: An axial oil filter including at least one pair of axially aligned filter elements includes an elongate filter body and a removable filter cartridge. The filter elements are mounted on an axial conduit which is a part of the filter cartridge, and the filter cartridge placed in the filter body so as to define upper and lower chambers, and a bypass flow path between the upper and lower chambers. Fluid to be filtered may flow into either of the chambers and will flow upward through the lower filter element and downward through the upper filter element. The filtered fluid is collected from a passage defined by a screen between the two filter elements, and passes outward from the filter through the outlet port.
