Abstract
Abstract An auxiliary container having a mounted position within an aquarium tank which compactly houses a pump and filter assembly and also forms the fluid connections for an efficiently operating water recirculation filtration system of which the pump and filter assembly are integral parts. The filter assembly is additionally readily removable for replacement of the filter material and, when replaced, readily establishes the necessary fluid connections for efficient operation of the filtration system.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
252 words
The combination for an aquarium of a tank including walls defining an internal volume serving as said aquarium having an upper opening bounded by the upper peripheral edges of said walls, and a hollow elongated auxiliary container having an operative seated position on said tank upper peripheral edges within said upper opening thereof and having a bottom wall in facing relation to said tank interior volume, said auxiliary container having transverse walls delineating the internal volume thereof into a least a pump compartment and a filter assembly compartment, a pump and pump housing operatively arranged in a depending position from said pump compartment bottom wall into said tank internal volume, said pump housing having an inlet and an outlet in communication with said pump, said filter assembly compartment bottom wall having an inlet thereto and an outlet therefrom in communication with said tank internal volume, a conduit connected from said pump outlet to said filter assembly compartment inlet effective to deliver water for filtering into said filter assembly compartment, and a self-contained filter assembly positionable in said filter assembly compartment having an operative connection to said filter assembly compartment inlet and outlet and having filter material interposed between said operative connections for filtering said water during passage through said filter assembly, said filter assembly including a housing having an upper wall and a spray nozzle mounted therein in communication with said filter assembly inlet operative connection so as to spray said water delivered to said filter assembly against said housing upper wall.
Claim 2
Dependent Claim
252 words
The combination for an aquarium of a tank including walls defining an internal volume serving as said aquarium having an upper opening bounded by the upper peripheral edges of said walls, and a hollow elongated auxiliary container having an operative seated position on said tank upper peripheral edges within said upper opening thereof and having a bottom wall in facing relation to said tank interior volume, said auxiliary container having transverse walls delineating the internal volume thereof into a least a pump compartment and a filter assembly compartment, a pump and pump housing operatively arranged in a depending position from said pump compartment bottom wall into said tank internal volume, said pump housing having an inlet and an outlet in communication with said pump, said filter assembly compartment bottom wall having an inlet thereto and an outlet therefrom in communication with said tank internal volume, a conduit connected from said pump outlet to said filter assembly compartment inlet effective to deliver water for filtering into said filter assembly compartment, and a self-contained filter assembly positionable in said filter assembly compartment having an operative connection to said filter assembly compartment inlet and outlet and having filter material interposed between said operative connections for filtering said water during passage through said filter assembly, said filter assembly including a housing having an upper wall and a spray nozzle mounted therein in communication with said filter assembly inlet operative connection so as to spray said water delivered to said filter assembly against said housing upper wall.
Claim 3
Dependent Claim
52 words
An aquarium auxiliary container as defined in claim 1 wherein said filter assembly compartment has upstanding mounting members for seating said filter assembly housing thereon in a clearance position from said compartment bottom wall so as to define a water outlet passage from said filter assembly to said filter assembly compartment outlet.
Claim 4
Dependent Claim
55 words
An aquarium auxiliary container as defined in claim 2 wherein said filter assembly compartment inlet comprises an upstanding conduit and said filter assembly housing has an opening in the bottom wall thereof in a location aligning with and accommodating said conduit therein in said seated position of said filter assembly within said filter assembly compartment.
Claim 5
Dependent Claim
206 words
The combination for an aquarium of a tank including walls defining an internal volume serving as said aquarium having an upper opening bounded by the upper peripheral edges of said walls, and a hollow elongated auxiliary container having an operative seated position on said tank upper peripheral edges within said upper opening thereof and having a bottom wall in facing relation to said tank interior volume, said auxiliary container having transverse walls delineating the internal volume thereof into at least a pump compartment and a filter assembly compartment, a pump and pump housing operatively arranged in a depending position from said pump compartment bottom wall into said tank internal volume, said pump housing having an inlet and an outlet in communication with said pump, a conduit connected from said pump outlet to said filter assembly compartment effective to deliver water for filtering into said Filter assembly compartment, and a self-contained filter assembly having a spray nozzle and cover in facing relation and filter material beneath said cover positionable in said filter assembly compartment with said spray nozzle in fluid communication with said conduit from said pump outlet, whereby water delivered into said filter assembly is first sprayed against said cover before draining through said filter material.
Claim 6
Dependent Claim
206 words
The combination for an aquarium of a tank including walls defining an internal volume serving as said aquarium having an upper opening bounded by the upper peripheral edges of said walls, and a hollow elongated auxiliary container having an operative seated position on said tank upper peripheral edges within said upper opening thereof and having a bottom wall in facing relation to said tank interior volume, said auxiliary container having transverse walls delineating the internal volume thereof into at least a pump compartment and a filter assembly compartment, a pump and pump housing operatively arranged in a depending position from said pump compartment bottom wall into said tank internal volume, said pump housing having an inlet and an outlet in communication with said pump, a conduit connected from said pump outlet to said filter assembly compartment effective to deliver water for filtering into said Filter assembly compartment, and a self-contained filter assembly having a spray nozzle and cover in facing relation and filter material beneath said cover positionable in said filter assembly compartment with said spray nozzle in fluid communication with said conduit from said pump outlet, whereby water delivered into said filter assembly is first sprayed against said cover before draining through said filter material.
