Abstract
Abstract A novel toilet system is disclosed which is alternatively operable on a recirculating fluid supply or an external water supply. A foot-operated pedal, in combination with a switch selector, opens a mechanical seal to a holding tank and energizes the flushing operation. A novel, slide valve directs the flushing fluid from the selected source. In a specific embodiment, the toilet retracts into a wall fixture and combines a movable bowl member with a fixed receiver member. Separate flush lines clean the bowl and the receiver when in the retracted configuration.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
154 words
A dual mode toilet system including a toilet adapted to connect to a holding tank alternatively operable as a recirculating system and a running water system comprising: 1. pump and filter means adapted to mount in the tank, and operable to filter and recirculate flushing liquid as a source thereof; 2. running water supply means adapted to connect to a source of running water; 3. flush manifold means connected to said pump and filter means and to said running water supply means for flushing the toilet; 4. selector switch means connected to said pump and filter means and between said running water supply means and said flush manifold means, including a valve for preventing the flow of running water to said flush manifold and further including means for disabling said pump filter means; and 5. flushing means including means for simultaneously enabling both said pump and filter means and said running water supply means.
Claim 2
Dependent Claim
154 words
A dual mode toilet system including a toilet adapted to connect to a holding tank alternatively operable as a recirculating system and a running water system comprising: 1. pump and filter means adapted to mount in the tank, and operable to filter and recirculate flushing liquid as a source thereof; 2. running water supply means adapted to connect to a source of running water; 3. flush manifold means connected to said pump and filter means and to said running water supply means for flushing the toilet; 4. selector switch means connected to said pump and filter means and between said running water supply means and said flush manifold means, including a valve for preventing the flow of running water to said flush manifold and further including means for disabling said pump filter means; and 5. flushing means including means for simultaneously enabling both said pump and filter means and said running water supply means.
