I, JAMES LAWSON, of 6 Grange Road, Edinburgh, Scotland, Plumber, do hereby
declare the nature of my said invention to be as follows:-
The object of my invention is to manufacture an improved arrangement of water
closet, flushing apparatus, and water economiser.
In carrying out my invention, I fit a small cistern, containing the flushing water, at
a suitable height above the level of the closet basin, to impart the necessary force to
the water when issuing from the flushing pipe into the basin. The small cistern is
self-supplying by means of a ball-cock, as usual.
In the small cistern a vertical pipe rises therein from the bottom to a suitable height,
according to the size of the cistern, and the quantity of water required for flushing the
basin. This pipe may however be otherwise arranged, and placed in other positions,
inside the cistern. The flushing pipe a continuation of the supply pipe to the basin.
There is no valve required in the action of the closet.
An air tight vessel or float of suitable size and bulk is suspended in the water
contained in the small cistern, by levers; and the seat of the closet is made to rise and
fall one inch, and is so connected to the levers that, when a person sits upon the seat,
the levers.lift the float out of the water in the cistern, which operation causes the ball-
cock to fall, and thereby fill the cistern to the former level, and, when the person leaves
the seat, the float descends, and raises the level of the water in the cistern, which over-
flows and runs down the flushing pipe, until the water in the cistern is exhausted, to
the level of the mouth of the pipe, after which the cistern is again immediately filled
by the action of the ball-cock.
The basin with the fitting underneath combined, forms a trap, which causes two
inches of water to stand in the basin.

declare the nature of my said invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
The object of my invention is to manufacture an improved arrangement of water
closet flushing apparatus and water economiser.
In carrying out my invention, I fit a small cistern, containing the flushing water, at
a suitable height above the level of the closet basin, to impart the necessary force to

self supplying by means of a ball-cock, as usual.
In the small cistern a vertical pipe rises therein from the bottom to a suitable height
according to the size of the cistern, and the quantity of water required for flushing
the basin. This pipe may however be otherwise arranged, and placed in other positions
inside the cistern. The flushing pipe is a continuation of the supply pipe to the basin.
There is no valve required in the action of the closet.
An air tight vessel or float of suitable size and bulk is suspended in the water
contained in the small cistern, by leyers; and the seat of the closet is made to rise and
fall one inch, and is so connected in the levers that, when a person sits upon the seat,
the levers lift the float out of the water in the cistern, which operation causes the ball-
cock to fall, and thereby fill the cistern to the former level, and, when the person leaves
the seat, the float descends and raises the level of the water in the cistern, which over-
flows and runs down the flushing pipe until the water in the cistern is exhausted to
the level of the mouth of the pipe after which the cistern is again immediately filled
by the action of the ball-cock."
The basin, with the fitting underneath combined, forms a trap, which causes two
inches of water to stand in the basin..
And in order that my said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar letter of
'reference indicate corresponding parts.
Fig. 1 is a perspective view of the apparatus and basin with the front portions*
removed to shew the construction, and Fig. 2. is an enlarged perspective view of the
basin.
a is the cistern, b is the flushing pipe leading from the cistern to the basin. The
cistern is self supplying by means of the ball cock c, which may take the supply from
the main pipe service or from another cistern at a suitable height. d is a double
vertical pipe or syphon rising from the bottom of the cistern to a suitable height
according to the size of the cistern and the quantity of water required for flushing the
basin. The flushing pipe 6 leading to the basin, is a continuation of the vertical pipe d
in the oistern there are no valves used in the action; but an air-tight vessel
able size and bulk, is suspended in the water in the cistern by a lever, and the seat of
e,
of suit-

page_text: the water closet works on pivots at g which are placed at about a third of the width of
seat from the back; the movable seat is connected to the Vessel-Lever f, by an inter-
mediate smaller lever, h, when using the seat the levers lift the air-tight vessel e, out
of the water, whereby the water level is lowered, causing the ball-cock c, to open and
fill the cistern to the former level; and, when the seat is released, the air-tight vessel e,
descends, charging the flushing pipe b, which runs until the water in the cistern is
exhausted, and the cistern is again filled by the ball-cock c.
The Water Closet.is made in two pieces as shewn in Fig. 2, and is of white earthon-
ware, and they are so fitted together that the under part can be roversed to suit the
soil-pipe, whether it be placed in the front, or at the back, or side of the Closet, forming
a trap with a seat of two inches and a half or thereabouts.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is :-
1. The manufacture and use of self-acting water-closets substantially as hereinbefore
described and shewn on the drawings.
2. In self-acting water closets as aforesaid the use and application of the valveless
flushing apparatus constructed and operating substantially as described and shewn on
the drawings.
3. In self-acting water-closets as aforesaid, the use of the basin and trap constructed
and operating substantially as hereinbefore described and shewn on the drawings.
