Improvements in Automatic Flushing Water Closets, for Private and
Public Buildings, Ships and the like.
I, JOHN SHAW, 28, Rosehill Terrace, Willington-on-Tyne, Northumberland, Iron-
founder, do hereby declare the nature of this invention to be as follows;-
My invention relates to improvements in water closets for private and public
buildings ships and the like.
It consists of basin, internal pipe, S pipe for water seal, springs or weights,
racks and quadrents, water receiver and valve taps for same.
The object of my invention is to dispense with flushing tanks over head which
is expensive. Instead I provide a receiver which only holds the quantity of water
for one flush, with this invention you have a much powerfuller flush. The basin
or vessel is provided with an outlet at bottom.
The internal pipe is provided a bellmouth at top and secured to the seat and
a resess at bottom for a cushion ring.
The S pipe is provided with a flang to rest on.
The rack is made fast to the seat, the valve tap with quadrent is secured to the
water supply pipe from the said receiver, which provided with an inlet pipe, and
another valve tap.
When in use the operator sits on the seat the weight of the operator presses the
seat with internal pipe down onto the bottom of basin or vessel the said cushion
ring forms a water tight joint around the outlet of basin, at the same time the
rack and quadrent turns on the water from the receiver, and closes the supply
valve to the receiver by this means you only get the quantity of water required
for one flush, which is a saving in water.
When the operator rises the springs or weights lifts the seat again, and closes the
valve from receiver, and opens the water supply valve, and fills the receiver for
the next flush.
With this invention the water rushes into the S trap and carries all before it
which will be a saving in water, as the capasity of receiver is only made to contain
water for one flush. And the said receiver can be fixed vertically or horizontally,
which is most convenient.

page_text: same is to be performed, to be particularly described and ascertained in and by
the following statement; -
My invention relates to improvements in water closets for private and public
buildings, ships, and the like.
It consists of basin, internal pipe, S pipe for water seal, springs or weights,
rack and pinion, water receiver, valves, and taps for same, made of earthenware,
cast iron, or other suitable material, glazed or enamelled.
The object of my invention is to dispense with flushing tanks over head, which
are expensive. Also a much more powerful flush. Instead I provide a receiver
which only holds the quantity of water for one Hush, and washing down inside
of internal pipe. The basin or vessel is provided with an outlet at bottom. The
internal pipe is provided with a bellmouth at top, and secured to the under seat
or frame, and a recess at bottom for a cushion ring, for making a water tight
joint. The S pipe is provided with a flange at bottom to rest on. The receiver
is provided with a bracket inside for valve rod. The rack or bracket is made fast
to the under seat or frame the valve or tap with pinion is secured to the
water supply pipe from the receiver when fixed in a horizontal position.
When the said receiver is fixed in vertical position, it is provided
•
a
with two ball valves and seats, one at top and one at bottom.
When in use the user sits on the seat, the weight of the user presses the seat
with internal pipe down onto the bottom of the basin or vessel, the said cushion
rings forms a water tight joint around the outlet of basin. At the same time
the water is turned on from the receiver, and the supply valve to the said receiver
is closed. By this means you only get the quantity of water required for one flush.
When the user rises, the springs or weights raises the seat or frame again
and closes the valve from the receiver, and opens the water supply valve, and fills
the receiver ready for next flush. With this invention the water rushes into the S
trap and carries all before it into the sewer. There will also be a saving of water
as the capacity of receiver is only made to contain one flush. The said receiver
can be fixed horizontally or vertically.
DESCRIPTION OF DRAWINGS.
In the accompanying drawings my invention is shewn as it is to be carried out
in practical application.
Fig. 1 is a side section of water closet and a vertical receiver (scale 3 inches
one foot.
Fig. 2 is a front elevation of same.
The same letters refer to all corresponding parts on all the figures.
A is the basin, B is the internal pipe, C is the receiver, D is the S trap pipe,
E is the supply pipe, F F are the ball valves with rod attached, G is the connecting
pipe between the receiver and basin, H is the piston on end of valve rod, I is the
weight on end of lever bracket, J is the lever bracket, K is the under seat or
frame with bracket J attached, L is the upper seat balanced to rise up, so that K
can be used as a urinal, M and N are the ball valve seats, P are small holes in
the internal pipe for washing down inside of same, Q is the cushion for making
water-tight joint.
When in use as a water closet, the user brings L down on K to sit on, when
the user is seated the front of seat drops down and presses the cushion ring Q
onto its seat at bottom of basin A and forms a water tight joint, and at the same
time the lever bracket J rises and opens the bottom valve F, and closes the top
valve F and lets the water out of receiver C into the basin A. As soon as the water
rises to the small holes P in B, the water washes down inside of B.
As soon
as the user arises the weight I raises the seat K and pipe B, and the water in A
rushes into the S trap D, and carries all before it. At the same time it closes
the bottom valve F, and opens the top valve F to fill the receiver again for the
next flush.

page_text: This invention is not depending on the area of a 1½in. pipe, from flushing
tank to basin, for flushing and cleansing a four inch S trap and soil pipe, which
is not one fifth the area. I my invention as soon as the user arises the whole
of the water in said basin rushes into the S trap, down the soil pipe, forming at
least a three foot column of water carrying all before it right through the drain
into the sewer. By this means you will always have a clear and clean drain.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1st. The internal pipe B which forms a water tight joint on bottom of basin or
vessel.
2nd. The receiver C which contains the water for flushing and the ball valves,
and Beats for same.
3rd. An automatic flushing water closet constructed substantially as described
with reference to the drawings and operating as and for the purpose specified.
