Dump bucket toilet

A dump bucket toilet which includes a toilet bowl, a tank having upper and lower portions and having an outlet in said lower portion which is coupled to said toilet bowl to flow water thereto, a bucket which lies at least primarily in said tank and which is pivotally mounted about a horizontal axis to pivot from an initial position in a first direction to dump water for exit through said outlet and in an opposite direction back to said initial position, and an inlet valve positioned to refill said bucket, characterized by:

• a manually operable control which is operable in a first full-flush mode to pivot said bucket in said first direction from said initial position, by a first angle, to release almost all water from said dump bucket;
• said manually operable control being operable in a second partial-flush mode to pivot said dump bucket in said first direction from said initial position, by a second angle which is less than said first angle, to a partial release position to release less water than when pivoted to said full release position;
• said manually operable control including a stop which is positioned in the path of pivoting of said dump bucket in said first direction from said initial position to stop pivoting of said bucket by more than said second angle, when said control is operated in said second mode, but which is positioned out of the path of said bucket when said control is operated in said first mode.

A dump bucket toilet which includes a toilet bowl, a tank having opposite tank walls and upper and lower portions, said opposite tank walls each having a top edge with a largely upwardly-facing surface and said tank having an outlet in said lower portion which is coupled to said toilet bowl to flow water thereto, a dump bucket which has front and rear bucket sides and which can pivot about a primarily horizontal pivot axis to tip and release water into said tank so the released water can flow out through said outlet, and an inlet valve positioned to refill said bucket, characterized by:

• a bucket support that includes a substantially stationary mount portion having opposite ends each mounted on said tank upper portion at a location above said pivot axis, said bucket support having a substantially stationary support portion which extends downwardly from said mount portion and which supports said bucket in pivoting about said axis;
• each of said mount portion ends rests on one of said tank top edges at one of said largely upwardly-facing surfaces thereat;
• a rod extending substantially along said pivot axis through said bucket between said bucket sides;
• said support portion comprises a member having a lower end that is pivotally connected to said rod at a position halfway between said bucket sides.

A dump bucket toilet which includes a toilet bowl, a tank having opposite tank walls and upper and lower portions with said lower portion forming a lower wall with an outlet extending therethrough, said opposite tank walls each having a top edge with a largely upwardly-facing surface and said outlet being coupled to said toilet bowl to flow water thereto, a dump bucket which can pivot about a primarily horizontal pivot axis to tip and release water into said tank so the released water can flow out through said outlet, and an inlet valve positioned to refill said bucket, characterized by:

• a bucket support that includes a mount portion having opposite ends each resting on one of said tank top edges at one of said largely upwardly-facing surfaces thereat at a location above said pivot axis, said bucket support having a support portion which extends downwardly from said mount portion and which supports said bucket in pivoting about said axis, with said support portion being substantially stationary when said toilet is in use and said bucket pivots as well as when said toilet is not in use and said bucket does not pivot;
• a funnel having a lower end coupled to said outlet of said tank and having an always open upper end extending at least four inches above said lower wall;
• said tank holding water of a height of at least four inches above said lower wall and up to the level of the top of said funnel, between flushings;
• said dump bucket being positioned to dump water into said tank only at a location spaced from said funnel.

• each of said mount portion ends rests on one of said tank top edges at one of said largely upwardly-facing surfaces thereat;
• said dump bucket has an upper outward end which moves with a downward directional component when said bucket pivots in a first direction to release water at the beginning of a flushing, and has an inner upper end portion that moves with an upward directional component when said bucket pivots in said first direction, said bucket being pivotable by a maximum of a first angle to a full release position to release almost all water from said bucket;
• said bucket inner upper end portion is primarily straight and has a length of at least one inch and is angled to extend primarily horizontally when said bucket lies in said full release position.

Apparatus for use in a dump bucket toilet that includes a tank with front and rear tank walls that each have an upper end portion with an upper edge, said tank also having a lower portion, comprising:

• a bucket having a horizontal pivot axis;
• a support constructed to mount on said tank, said support having a mount portion with front and rear ends that each have a downwardly-facing surface for resting on a corresponding one of said upper end portions of said tank walls, and said support having a primarily downwardly-extending support portion with a lower end which is pivotally connected to said bucket to support said dump bucket in pivoting about said pivot axis, with said support being substantially stationary during use of the toilet when said dump bucket pivots;
• said mount portion has at least one abutment positioned to abut one of said tank walls;
• said abutment is fixable in each of a plurality of positions spaced in a direction parallel to said pivot axis.
