Claim 9

A tank of the type claimed in claim 1 wherein said tank includes transverse walls extending between opposed walls of said tank and extending substantially throughout the length of said tank to divide said tank into at least three compartments, at least a pair of said transverse walls being apertured and positioned on opposite sides of and extending substantially between said first and second seats to form said cage-like restrictive means for guiding said two float means, said vent means communicating the upper end of a compartment which is in lateral communication with said cage-like restrictive means, said vent means including third seat means, third float means adapted to close said vent when the water level reaches a predetermined point in the tank, said vent means communicating through a passage with the lower end of said tank, anti-syphon means adjacent the lower end of said tank to accept the discharge through said first bore and said vent means passage.

Claim 10

A tank of the type claimed in claim 8 wherein said anti-syphon means includes means for mounting to a support adapted to accept the weight of the tank, a central bore larger than and capable of accepting a projection containing said first bore with an ambient vent, canted surfaces leading downwardly to said bore, baffles extending vertically from said surfaces, said vent passageway discharging into said anti-syphon means at a point laterally removed from said central bore, said central bore being connected to a discharge pipe communicating with a toilet, whereby said ambient vent around said projection containing said first bore plus the baffle arrangement between said vent passageway and said central bore precludes any syphon action and contamination between said toilet and an inlet water supply connected to said second bore.

Claim 11

An anti-syphon wall enclosed flush tank for use with a toilet including a generally rectangular tank having a plUrality of transverse axially extending reinforcing members dividing the tank into generally elongated compartments, first and second bores communicating through the bottom and top of the tank with a generally centrally located compartment, said central compartment communicating laterally with any adjacent compartments, an angularly disposed first seat means surrounding said first discharge bore at the bottom of said tank, resilient impermeable floatable ball means adapted to seat upon and seal with said first seat means, second seat means surrounding said second inlet bore means at the top of the tank which is connected to a pressurized water source, second float means adapted to cooperate with said second seat means to shut off said water source at a predetermined water level in said tank, vent and overflow passage means communicating with an adjacent chamber, third seat means surrounding said passage means, a third float means adapted to cooperate with said third seat means to seal said vent and overflow passage at a predetermined water level in said tank, said vent and overflow passage at its opposite end of said tank, operator means including one or more means for contacting and unseating said ball from said first seat, blocking means for preventing discharge of the water from said tank during the unseating of said ball and an anti-syphon device including means for mounting said device to a support adapted to accept the weight of the tank and the water to be contained therein, said anti-syphon device being open to ambient conditions, a central bore larger than and capable of accepting in spaced ambient venting relation a delivery means containing said first bore depending from said tank, baffled surface means draining into said central bore, said vent and overflow passage discharging onto said baffled surface for drainage, if any, into said central bore which is connected to suitable means for discharge of said water into said toilet upon actuation of said operator means or discharge from said vent and overflow passage, means for hanging said toilet in axially spaced relation from the same supports holding the anti-syphon device and tank.

Claim 12
