CARTRIDGE FOR A FILTER ASSEMBLY
This application claims the benefit of U.S. Provisional application No.
60/ 130, 576, filed April 21, 1999 DESCRIPTION OF INVENTION
The invention relates to an above deck mountable filter cartridge for a filter assembly and particularly relates to an above deck mountable filter cartridge for a filter assembly that is top loaded for installation or replacement of the filter cartridge disposed in a filter cartridge housing mounted in a sink hole or an opening in the deck or the deckplate. A top member or cap is affixed to the filter cartridge housing from above the deck or deckplate to secure the filter cartridge in the housing or upon removal of the cap provides quick and easy access to or to replacement of the filter cartridge. The filter cartridge housing is provided with inlet and outlet lines for water that are connected to the housing below the deck.
BACKGROUND OF THE INVENTION
Prior art filtering devices used filters or filter cartridges that were mounted from below the deck or mounted in the spout or mounted in the spray head of the spout. Each of the prior art devices had disadvantages such as: the below deck devices were inconvenient and lacked ready access to or replacement of the filter devices; the filter devices mounted in the spout provided limited access and required a larger diameter spout; and the filter devices mounted in the spray head made the 2o spray head large, heavy and difficult and awkward to change the filter devices.

Other objects, features and advantages of the present invention will become more fully apparent from the following detailed description of the present invention, is the appended claims and the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWING
FIG. 1 is a sectional side elevational view of the filter assembly according to the present invention.
DETAILED DESCRIPTION OF THE PREFERRED
EMBODIMENT OF THE INVENTION
FIG. 1 illustrates the preferred embodiment of the present invention of a 2s filter assembly 8 that has a filter cartridge 10 which is formed with an inlet end 12 having a plurality of inlet openings (not shown) therein and an outlet end 14 which Ariy. Ref. 5310-25 (6736-000006) terminates in a cylindrical nozzle 16 formed about a central axis 18. A
cylindrical impervious cover 20 encloses the filter cartridge 10 by extending axially from the inlet end 12 to the outlet end 14. The filter cartridge 10 is formed with a uniform diameter along the full length of the cover 20 thereof.
The filter cartridge 10 will be filled with a suitable filter media such as, for example, granular activated carbon (GAC) which is useful for filtering the undesirable elements in the unfiltered water which are associated with chlorine, taste and odor. Other known water filtering media could be added to the GAC for effectively reducing various metals and minimizing any bacteria or other organisms to which may be in the water to be filtered. Also, iron exchange resins could be added to treat the water being filtered for color and taste. A pre-filter porous mesh could be used within the filter cartridge 10 adjacent to and inwardly of the inlet end I2 to preclude sediment and suspended particulate from interfering with the filtering action. Further, a post-filter porous material such as, for example, foam could be inserted into the filter cartridge 10 above the filter media adjacent the nozzle 16 at the outlet end I4 of the filter media within the filter cartridge 10 during processing and handling of the filter cartridge .10 prior to installing the filter cartridge 10 in the filter assembly 8.
The filter assembly 8 has a filter cartridge housing 22 with a cylindrical 2o shape of a diameter slightly larger than the diameter of the filter cartridge 10. An annular chamber 24 is formed in the space between the exterior of the cover 20 of the filter cartridge 10 and the interior of the housing 22. The annular chamber 24 extends substantially the full axial length of the housing 22. The upper section 26 of the housing 22 is externally threaded to threadedly receive a nut 28 that is shifted Atty. Ref. 5310-25 (6736-000006) into engagement with the under side 30 of a deck 32 having an opening 34 through which the housing 22 extends. A lock nut 36 is raised to engage and lock the position of the nut 28. The upper section 26 of the housing 28 extends through an opening 38 in a deckplate 40 and nut 42 threadedly engages the housing 22 above the deckplate 40 at its opening 38 to force the deckplate 40, to which the filter cartridge housing 22 is now connected, into engagement with the upper surface of the deck 32. Of course, if the deckplate 40 were not to be used, the filter cartridge housing 22 could be directly connected to the deck 32 at the deck opening 34 thereof. A union block 46 is connected to the lower end 56 of the to housing 22. The union block 46 includes an inlet chamber 48 with an inlet nipple 50 and an outlet chamber 52 with an outlet nipple 54 to which is connected an outlet connector 55. An inlet connector 58 is mounted in the inlet nipple SO to deliver inlet water therein as is shown by the directional arrow.
The filter cartridge 10 will be installed from above the top of the deck 32 into the filter cartridge housing 22 so that the inlet end 12 is disposed in the union block 46. The inlet end 12 of the filter cartridge 10 is suitably sealed from the f outlet chamber 52 and in communication with the inlet chamber 48 through an opening 60 at the bottom of the housing 22. Installation of the filter cartridge 10 in the housing 22 will place the cartridge nozzle 16 in an area surrounded by the opening 34 in the deck 32 and at about the same elevation thereof.
A cap 62 having a down-turned outer cover 64 extending over the nut 42 and an inner cylindrical portion 66 that is threadedly engaged in a leak-proof manner to internal threads formed at the top of the upper section 26 of the housing 22.
The cap 62 is closed by a horizontal member 68 to define a cap chamber 70 that has a Atty. Ref. 5310-25 (6736-000006) plurality of openings 72 formed at its lower end and a central projection 74 which has a central opening 76. The central projection 74 is engaged in and aligns with the cartridge nozzle 16 so that filtered water being discharged from -the filter cartridge 10 will enter the cap chamber 70. From the cap chamber 70, water is delivered through openings 72 into a filtered water chamber 76. From filtered water chamber 76, the water enters the annular chamber 24 for discharge into the outlet chamber 52 and the outlet nipple 54 and the outlet connector 55 connected thereto to be discharged therefrom in the direction shown by the generally horizontal arrow.
to Removal of the cap 62 will provide access from above the deck 32 to permit the filter cartridge 10 to be installed, inspected or replaced from above the deck 32.
The various components of the filter assembly 8 will be interconnected to each other in a leak-proof manner or, when necessary, suitable seals are disposed at the location of the various components to prevent leakage therebelween. See, for is example, bottom seal 51 and O-ring seal 53. Also, a spring member 78 may be disposed in the inlet chamber 48 to engage the bottom of the filter cartridge 10 and be compressed upon insertion thereof and connection of the cap 62 to complete the installation thereof. Once the cap 62 is removed, the spring 78 will expand to force the filter cartridge upwardly, expose the cartridge nozzle 16 or make it easier to 2o grasp to remove the filter cartridge 10 from the housing 22.
The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to ~e regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious Atty. Ref. 5310-25 (6736-000006) to one skilled in the art are intended to be included within the scope of the following claims .

The filter assembly 8 has a filter cartridge housing 22 with a cylindrical 2o shape of a diameter slightly larger than the diameter of the filter cartridge 10. An annular chamber 24 is formed in the space between the exterior of the cover 20 of the filter cartridge 10 and the interior of the housing 22. The annular chamber 24 extends substantially the full axial length of the housing 22. The upper section 26 of the housing 22 is externally threaded to threadedly receive a nut 28 that is shifted Atty.

An inlet connector 58 is mounted in the inlet nipple SO to deliver inlet water therein as is shown by the directional arrow.
The filter cartridge 10 will be installed from above the top of the deck 32 into the filter cartridge housing 22 so that the inlet end 12 is disposed in the union block 46. The inlet end 12 of the filter cartridge 10 is suitably sealed from the f outlet chamber 52 and in communication with the inlet chamber 48 through an opening 60 at the bottom of the housing 22.
