Abstract

Abstract An aquarium device for successful and economical growing of a concentrated number of fish from frys and fingerlings to maturity in a minimum of space, consisting of an upper fish habitat compartment, with a water-supply spray, and a lower control compartment separated by a slanted partition to guide waste matter and pollutants through an adjustable flow hole into the lower compartment. The water discharged into the lower compartment rises and presses the air in the lower compartment through an adjustable air control valve connected to an extension which releases air bubbles into the water of the upper compartment to aerate the water and to create a circulation which releases carbon dioxide into the atmosphere and which encourages contaminants to settle. A screen above the partition prevents the escape of fish through the discharge opening and does not permit them to disperse the contaminants which have settled. After the lower compartment is filled, the water is discharged automatically and fresh air enters. A valve is then closed and the process is continued. The adjustable air valve contains the conventional one-way flow feature which stops the downward flow of water. The adjustable flow hole includes a conventional pressure valve feature, which reduces the flow of water when the float controlled discharge outlet is opened to flush lower compartment. Safety features assure the continual removal of waste matter. A feeder is activated and controlled by the falling water supplying the aquarium. A conventional air pump can be used to aerate in emergencies. A conventional shallow pan, not shown, should be suspended submerged in water of upper aquarium compartment for feeding mash to small fry when they are being grown.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 252 words
An aquarium device for raising fish in concentrated quantities in a minimum space comprising an upper fish-growing aquarium compartment including a water supply therefor and a lower water control compartment, a downwardly inclined partition means between the compartments for separating them and guiding waste matter and other pollutants to the lower end at one side of the upper chamber, a first adjustable-discharge flow hole in the partition adjacent its lower end, an adjustable air-control valve at the upper end of said partition connecting the compartments and including an outwardly extending adjustable-length airdischarge means for releasing bubbles of air through the end thereof, said end being adjacent said first discharge hole, a second discharge means at a lower portion of said water control chamber including a first float operated closure valve therefor; a safety flow control valve means for said second discharge means, an operating means for said safety valve means including a second float in said growing compartment connected to a release means for said safety flow valve means, and an auxiliary water tank for control of water in said aquarium compartment, at a level at the top thereof, having an overflow outlet and a water siphon means connected thereto, said siphon means having an end remote from said auxiliary tank located adjacent said lower end of one side of the upper chamber whereby the flow of water from said aquarium tank is automatically controlled to cycles of filling and discharge at optium intervals for the size quantity of fish grown therein.
Claim 2
Dependent Claim 252 words
An aquarium device for raising fish in concentrated quantities in a minimum space comprising an upper fish-growing aquarium compartment including a water supply therefor and a lower water control compartment, a downwardly inclined partition means between the compartments for separating them and guiding waste matter and other pollutants to the lower end at one side of the upper chamber, a first adjustable-discharge flow hole in the partition adjacent its lower end, an adjustable air-control valve at the upper end of said partition connecting the compartments and including an outwardly extending adjustable-length airdischarge means for releasing bubbles of air through the end thereof, said end being adjacent said first discharge hole, a second discharge means at a lower portion of said water control chamber including a first float operated closure valve therefor; a safety flow control valve means for said second discharge means, an operating means for said safety valve means including a second float in said growing compartment connected to a release means for said safety flow valve means, and an auxiliary water tank for control of water in said aquarium compartment, at a level at the top thereof, having an overflow outlet and a water siphon means connected thereto, said siphon means having an end remote from said auxiliary tank located adjacent said lower end of one side of the upper chamber whereby the flow of water from said aquarium tank is automatically controlled to cycles of filling and discharge at optium intervals for the size quantity of fish grown therein.
Claim 3
Dependent Claim 75 words
An aquarium device as defined in claim 1 which includes a feeder means supported upon the upper compartment, a water wheel, with buckets, rotatable on an axis connected to the support, to receive power from the water supply, a spool with a series of troughs along its surface affixed around an extension of the axis to measure and dispense food as it turns beneath a hopper supported by a frame attached to the upper compartment.
Claim 4
Dependent Claim 34 words
An aquarium device as defined in claim 1 which includes a screen across the inside of the upper fish compartment, above the partition, to prevent the escape of fish and the agitation of sediment.
