Abstract

Abstract A fluid discharge regulating device to be used for conserving water in the toilet tanks of bathroom toilets. The device includes partitions that divide the toilet tank into three consecutively arranged compartments, each compartment providing fluid communication with other compartments, either directly or indirectly, through portholes in each partition. Each porthole opening is adjustable to control the rate of fluid flow into the second or middle compartment in order to maintain constant the amount of water used during a single flush. The volume of fluid reaching the toilet bowl can be increased beyond the preset level by holding down an adjustable handle which is connected to the flushing mechanism.

Total Claims: 20
Claim 1
Independent Claim 120 words
A tank for use in conjunction with a toilet having a bottom floor, a plurality of upstanding walls and flushing apparatus comprising: partitions dividing said tank into first, second, and third water-retaining compartments for conserving water during flushing of said toilet, portholes predeterminedly positioned in said partitions within close proximity to the bottom floor of said tank to provide for water flow from said first and third compartments into said second compartment during flushing of said toilet, gates pivotally mounted to said partitions to cover and uncover said portholes, and attachment means fastened to said gates to set the degree of gate rotation required for controlling the rate of water flow into said second compartment through said portholes during flushing.
Claim 2
Dependent Claim 120 words
A tank for use in conjunction with a toilet having a bottom floor, a plurality of upstanding walls and flushing apparatus comprising: partitions dividing said tank into first, second, and third water-retaining compartments for conserving water during flushing of said toilet, portholes predeterminedly positioned in said partitions within close proximity to the bottom floor of said tank to provide for water flow from said first and third compartments into said second compartment during flushing of said toilet, gates pivotally mounted to said partitions to cover and uncover said portholes, and attachment means fastened to said gates to set the degree of gate rotation required for controlling the rate of water flow into said second compartment through said portholes during flushing.
Claim 3
Dependent Claim 20 words
The tank of claim 1 in which said gates rotate about screws that movably secure said gates to said partitions.
Claim 4
Dependent Claim 49 words
The tank of claim 1 in which said partitions are fitted within said tank to conform to the contours of said tank and may be placed in the tank and securely pressed into engagement with said bottom floor and said walls of the tank without moving said flushing apparatus.
Claim 5
Dependent Claim 40 words
A toilet including a bowl and a tank in which said tank contains a bottom floor, a plurality of upstanding walls, flushing apparatus, and water-retaining barriers, said barriers comprising: partitions that divide said tank into first, second, and third compartments,
Claim 6
Dependent Claim 40 words
A toilet including a bowl and a tank in which said tank contains a bottom floor, a plurality of upstanding walls, flushing apparatus, and water-retaining barriers, said barriers comprising: partitions that divide said tank into first, second, and third compartments,
Claim 7
Dependent Claim 75 words
portholes positioned in each partition, gates pivotally mounted on each of said partitions and rotatively positionable over each of said portholes to provide for water flow from said first and third compartments into said second compartment through said portholes during flushing of said toilet, and attachment means fastened to said gates to set the degree of gate rotation required for controlling the rate of water flow into said second compartment through said portholes during flushing.
Claim 8
Dependent Claim 75 words
portholes positioned in each partition, gates pivotally mounted on each of said partitions and rotatively positionable over each of said portholes to provide for water flow from said first and third compartments into said second compartment through said portholes during flushing of said toilet, and attachment means fastened to said gates to set the degree of gate rotation required for controlling the rate of water flow into said second compartment through said portholes during flushing.
Claim 9
Dependent Claim 20 words
The toilet of claim 4 in which said gates rotate about screws that movably secure said gates to said partition.
Claim 10
Dependent Claim 46 words
The toilet of claim 4 in which said partitions are fitted to conform to the contours of said tank and may be placed in the tank and securely pressed into engagement with said bottom floor and said walls of the tank without moving said flushing apparatus.
Claim 11
Dependent Claim 30 words
The toilet of claim 4 in which an adjustable hold down means is coupled to said flushing apparatus for varying the volume of fluid delivered to said bowl during flushing.
Claim 12
Dependent Claim 122 words
A fluid discharge regulating means adapted to be used in conjunction with a toilet bowl and a flushing apparatus substantially surrounded by a toilet tank comprising: partitions that divide said tank into first, second, and third water-retaining compartments for conserving water during flushing of said toilet, portholes predeterminedly positioned in said partitions within close proximity to the bottom floor of said tank to provide for water flow from said first and third compartments into said second compartment during flushing of said toilet, gates pivotally mounted to cover and uncover said portholes, and attachment means fastened to said gates to set the degree of gate rotation required for controlling the rate of water flow into said second compartment through said portholes during flushing.
Claim 13
Dependent Claim 122 words
A fluid discharge regulating means adapted to be used in conjunction with a toilet bowl and a flushing apparatus substantially surrounded by a toilet tank comprising: partitions that divide said tank into first, second, and third water-retaining compartments for conserving water during flushing of said toilet, portholes predeterminedly positioned in said partitions within close proximity to the bottom floor of said tank to provide for water flow from said first and third compartments into said second compartment during flushing of said toilet, gates pivotally mounted to cover and uncover said portholes, and attachment means fastened to said gates to set the degree of gate rotation required for controlling the rate of water flow into said second compartment through said portholes during flushing.
Claim 14
Dependent Claim 23 words
The fluid discharge regulating means of claim 8 in which said gates rotate about screws that movably secure said gates to said partitions.
Claim 15
Dependent Claim 49 words
The fluid discharge regulating means of claim 8 in which said partitions are fitted to conform to the contours of said tank and may be placed in the tank and securely pressed into engagement with said bottom floor and said walls of the tank without moving said flushing apparatus.
Claim 16
Dependent Claim 33 words
The fluid discharge regulating means of claim 8 in which an adjustable hold down means is coupled to said flushing apparatus for varying the volume of fluid delivered to said bowl during flushing.
Claim 17
Dependent Claim 189 words
A fluid discharge regulating means adapted to be used in conjunction with a toilet bowl and a flushing apparatus substantially surrounded by a toilet tank comprising: partitions that divide said tank into first, second, and third water-retaining compartments for conserving water during flushing of said toilet, said partitions extending above the normal water line of said tank and said second compartment containing said flushing apparatus. a plurality of plugholes predeterminedly positioned in each of said partitions within close proximity to the bottom floor of said tank to provide for water flow from said first and third compartments into said second compartment during flushing of said toilet, and plugs insertable into said plugholes in each of said partitions for controlling the rate of water flow out of the two compartments through open plugholes into said second compartment during flushing, said plugs thereby adjustably controlling the amount of water reaching said toilet bowl during a flush sequence, the combination of said partitions, plugholes and plugs allowing for a combined flow rate from said three compartments during said flush sequence to provide a minimum amount of water needed for a complete flush.
