Abstract
Abstract A water closet assembly adapted to be mounted on any one of a variety of bases for discharge of waste material into a drainage system, a holding tank, or the like, and which includes features for making optimum use of the flush water. The assembly includes a bowl and a pivotally mounted pan for closing the discharge outlet of the bowl and shaped so that it can provide a water seal when the pan is in its closed position. The pan can be tilted to an open position to discharge the contents of the bowl, and the actuator mechanism for tilting the bowl is operable to open a valve so that flush water will flow into the bowl in timed relation to movement of the pan. The actuator mechanism is also operable to be moved in another direction so that water can be introduced into the bowl to a desired depth in the pan while the pan is in its closed position.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
195 words
A water closet comprising a bowl having an open lower end, a concave pan beneath said bowl and supported thereon adjacent to the upper end thereof for pivotal movement about a horizontal axis between a first position in which said pan encloses said open lower end and a second position in which said pan is tilted in an elevated position at one side of said bowl, said pan having a depth so that when in its first position its peripheral lip is at a higher elevation than the open lower end of said bowl, water flushing means actuable for discharging flush water to the interior of said bowl, and an actuator mechanism connected to said pan and to said water flushing means and selectively operable either (1) for moving said pan to its second position and simultaneously actuating said flushing means to deliver flush water to the bowl while the pan is tilted and for returning the pan to its first position and rendering said flushing means inactive, or (2) for actuating only said flush means to deliver a desired quantity of water to said bowl while said pan is maintained in its first position.
Claim 2
Dependent Claim
195 words
A water closet comprising a bowl having an open lower end, a concave pan beneath said bowl and supported thereon adjacent to the upper end thereof for pivotal movement about a horizontal axis between a first position in which said pan encloses said open lower end and a second position in which said pan is tilted in an elevated position at one side of said bowl, said pan having a depth so that when in its first position its peripheral lip is at a higher elevation than the open lower end of said bowl, water flushing means actuable for discharging flush water to the interior of said bowl, and an actuator mechanism connected to said pan and to said water flushing means and selectively operable either (1) for moving said pan to its second position and simultaneously actuating said flushing means to deliver flush water to the bowl while the pan is tilted and for returning the pan to its first position and rendering said flushing means inactive, or (2) for actuating only said flush means to deliver a desired quantity of water to said bowl while said pan is maintained in its first position.
Claim 3
Dependent Claim
92 words
The water closet that is defined in claim 1, wherein said water flush means includes a rotary ball valve for controlling flow of the flush water, and said actuating mechanism includes a rotary control means that is rotatable and is connected to said ball valve for rotating the latter in either direction of rotation between open and closed positions, said concave pan being operably connected to said rotary control means for pivoting from its first to its second position only in response to rotary movement of said control means in one direction.
Claim 4
Dependent Claim
166 words
A water closet comprising a bowl having an open lower end, a closure member mounted for movement between a first position in which it closes said open lower end and a second position in which it is at one side of the lower end of said bowl, water flushing means actuable for discharging flush water to the interior of said bowl, and an actuator mechanism connected to said closure member and to said water flushing means and selectively operable either (1) for moving said closure member to its second position and for simultaneously actuating said flushing means to deliver flush water to the bowl while the closure member is out of said first position and for returning the closure member to its first position and for rendering said flushing means inactive or (2) for actuating said flush means independently of said closure member, said actuator mechanism including a rotary control knob mounted for hand actuation in either direction of turning for selectively operating said actuator mechanism.
Claim 5
Dependent Claim
166 words
A water closet comprising a bowl having an open lower end, a closure member mounted for movement between a first position in which it closes said open lower end and a second position in which it is at one side of the lower end of said bowl, water flushing means actuable for discharging flush water to the interior of said bowl, and an actuator mechanism connected to said closure member and to said water flushing means and selectively operable either (1) for moving said closure member to its second position and for simultaneously actuating said flushing means to deliver flush water to the bowl while the closure member is out of said first position and for returning the closure member to its first position and for rendering said flushing means inactive or (2) for actuating said flush means independently of said closure member, said actuator mechanism including a rotary control knob mounted for hand actuation in either direction of turning for selectively operating said actuator mechanism.
Claim 6
Dependent Claim
50 words
The water closet that is defined in claim 3, wherein said water flush means includes a rotary ball valve for controlling flow of the flush water, said rotary control knob being operably connected to the stem of the ball valve for turning said ball valve in either direction of rotation.
