Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
91 words
A toilet having a bowl with an outlet at its bottom and an inlet water supply means for supplying flush water to said bowl, said inlet supply means comprising a passageway, a measuring device in said passageway for measuring a preselected volume of water, and a nozzle in communication with said measuring device and positioned to direct the preselected volume of water in a vortex pattern into said bowl, said measuring device being responsive to fluid pressure from an external source to discharge the fixed volume of water to said nozzle.
Claim 2
Dependent Claim
91 words
A toilet having a bowl with an outlet at its bottom and an inlet water supply means for supplying flush water to said bowl, said inlet supply means comprising a passageway, a measuring device in said passageway for measuring a preselected volume of water, and a nozzle in communication with said measuring device and positioned to direct the preselected volume of water in a vortex pattern into said bowl, said measuring device being responsive to fluid pressure from an external source to discharge the fixed volume of water to said nozzle.
Claim 3
Dependent Claim
42 words
A toilet as is defined in claim 1, wherein said measuring device contains a chamber means of said preselected volume, said chamber means having an outlet through which the water is discharged and an inlet in communication with a sourcE of water.
Claim 4
Dependent Claim
18 words
A toilet as is defined in claim 2, wherein said chamber means is a normally expanded resilient bellows.
Claim 5
Dependent Claim
115 words
A toilet having a bowl with an outlet at its bottom and an inlet water supply means for supplying flush water to said bowl, said inlet supply means comprising a passageway, a measuring device in said passageway for the measurement of a preselected volume of water, and a nozzle in communication with said measuring device and positioned to direct the preselected volume of water in a vortex pattern into said bowl, a fluid passage means associated with said passageway, said measuring device being in a pressure responsive position to the fluid in said passage means for acting in response to the pressure of said fluid to discharge the fixed volume of water to said nozzle.
Claim 6
Dependent Claim
115 words
A toilet having a bowl with an outlet at its bottom and an inlet water supply means for supplying flush water to said bowl, said inlet supply means comprising a passageway, a measuring device in said passageway for the measurement of a preselected volume of water, and a nozzle in communication with said measuring device and positioned to direct the preselected volume of water in a vortex pattern into said bowl, a fluid passage means associated with said passageway, said measuring device being in a pressure responsive position to the fluid in said passage means for acting in response to the pressure of said fluid to discharge the fixed volume of water to said nozzle.
Claim 7
Dependent Claim
29 words
A toilet as is defined in claim 4, wherein said passage means for a fluid is a segment of said passageway, and said fluid is water from said source.
Claim 8
Dependent Claim
24 words
A toilet as is defined in claim 5, wherein the inlet of said pressure means is a restricted aperture open to said passage means.
Claim 9
Dependent Claim
28 words
A toilet as is defined in claim 4, wherein said passage means for a fluid is separate from said passageway, and said fluid is a gas under pressure.
Claim 10
Dependent Claim
26 words
A toilet as is defined in claim 7, wherein the inlet of said pressure means is a restricted aperture in communication with said source of water.
Claim 11
Dependent Claim
34 words
A toilet as is defined in claim 5, wherein a normally closed valve is in said passageway upstream from said chamber means adapted when opened to direct water under pressure to said chamber means.
Claim 12
Dependent Claim
50 words
A toilet as is defined in claim 9, wherein a closure valve member is in a normally closed position in the outlet of said bowl, said normally closed valve being operably connected to said closure valve member to be opened and closed when said valve member is opened and closed.
Claim 13
Dependent Claim
50 words
A toilet having a bowl with an outlet at its bottom and an inlet water supply means for supplying flush water to said bowl, said inlet supply means comprising a passageway and means in said passageway to direct a selected volume of water in a vortex pattern into said bowl.
Claim 14
Dependent Claim
50 words
A toilet having a bowl with an outlet at its bottom and an inlet water supply means for supplying flush water to said bowl, said inlet supply means comprising a passageway and means in said passageway to direct a selected volume of water in a vortex pattern into said bowl.
