COMPLETE SPECIFICATION.
Improvements in Water-closet Apparatus.
I, WILLIAM ROBERT LAKE, of the firm of Haseltine Lake & Co, Patent Agents,
Southampton Buildings in the County of Middlesex do hereby declare the nature
of my invention for "IMPROVEMENTS IN WATER-CLOSET APPARATUS" and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention relates to improvements in water closets and consists partly in
the combination of a water closet basin formed to constitute a stench trap, a waste
pipe or passage leading therefrom and so constructed as to form another stench
trap, a source of water, a pipe for conveying water to the basin, an air pipe leading
from the space in the waste pipe, or passage which is between the two stench
traps, and an injector connected with the said water pipe and the air pipe and
serving to produce a partial vacuum in said space by the flow of water through the
injector.
The invention also partly consists in the combination of a water closet basin
formed to constitute a stench trap, a waste pipe or passage leading therefrom and
so constructed as to form another stench trap, a water tank, a water pipe leading
from the tank to the basin, an air pipe leading from the space in the waste pipe
which is between the two stench traps, an injector having its inner tube connected
with the water-tank and in communication with the water pipe and its outer tube
in communication with the air pipe and the water pipe, whereby the flow of water
from the tank through the injector is made to produce a partial vacuum within
the space in the waste pipe which is between the two stench traps, a valve a lever
connected thereto, and a cord attached to the lever.
The invention partly consists in the combination of a water closet basin formed
to constitute a stench trap, a waste pipe or passage leading therefrom and so
constructed as to form another stench trap, a source of water, a pipe for conveying
water to the basin, an air pipe leading from the space in the waste pipe or passage

page_text: which is between the two stench traps, an injector connected with the water pipe
and the air pipe and serving to produce a partial vacuum in said space by the flow
of water through the injector and a valve in said air pipe between the injector and
the space in the waste pipe which is between the two stench traps.
When the valve controlling the passage of water through the water pipe is
opened by a pull on the cord and consequent oscillation of the lever water will
flow down said pipe, a partial vacuum will be produced in the space between the
two stench traps and the contents of the basin and of the stench trap comprised
therein will be caused to flow out by the force of the atmospheric pressure as well
as by the force of gravity.
The accompanying drawing is a central vertical section of a water closet basin,.
and appurtenances embodying my improvement.
A designates a basin which may be made of earthenware or any other suitable
material. It has a side outlet, and at the outlet is provided with an upwardly
extending flange a and a downwardly extending flange b. The flange a extends
above the bottom of the flange b.
From the outlet of the basin a pipe or passage B which may be made of iron or
of the same kind of material as the basin extends downwardly, then upwardly and
then downwardly again to connect with waste pipe of the water closet. The
peculiar form of this pipe or passage causes water to lodge in it to such an extent
as to close it or obstruct the passage of gases through it. It therefore forms a
stench trap. The extension of the flange a above the lower edge or bottom of the
flange b causes water to lodge in the basin and forms a stench trap in the basin,
preventing gases from rising from the pipe or passage B into the basin.
C designates a tank containing water for flushing the basin. D designates an
injector connected to the lower part of the tank C. E designates a pipe leading
from the injector D to a passage p around the upper part of the basin A and
conducting water to this passage. The water is supplied to this passage and
escapes around the lower edge into the basin.
As here shown the inner tube fof the injector is formed with the tank and
the outer tube g of the injector is formed with the pipe E, but the injector may be
entirely separate from the said tank and pipe and connected thereto by bolts or
otherwise.
Communication between the tank and the inner tube f of the injector may be
controlled by a valve F. The valve shown is a poppet valve and its spindle or
stem is connected by a link G to a lever which is fulcrumed to a stand erected on
the tank.
The lever H may be operated so as to open the valve F by pulling on a cord I
which is attached to it so as to hang down near the basin.
A pipe J extends from that portion of the pipe or passage B which is between
the two stench traps to the outer tube g of the injector hence when the valve F is
opened and water flows through the inner tube of the injector to the basin air is
drawn through the outer tube g of the injector from the pipe J and a partial
vacuum formed in that portion of the pipe or passage B which is between the two
stench traps. The water is thus caused to flow under the influence of atmospheric
pressure from the upper stench trap into the pipe or passage B.
A valve V may be arranged in the pipe J so as to close the same except when
the injector operates to exhaust air from the pipe. The valve shown is a poppet
valve and seats itself by its gravity for the purpose of closing the pipe. It is
raised from its seat to open the pipe by the air which is drawn out by the
injector.
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
First. The combination with a water closet basin formed to constitute a stench
trap, a waste pipe or passage leading therefrom and so constructed as to form a

page_text: stench trap, a source of water, a pipe for conveying water to the basin, and an air
pipe leading from the space in the waste pipe or passage which is between the
stench traps, of an injector connected with the said water pipe and the air pipe and
serving to produce a partial vacuum in said space by the flow of water through the
injector substantially as specified.
Second. The combination with a water closet basin formed to constitute a stench
trap a waste pipe or passage leading therefrom and so constructed as to form a
stench trap, a water tank, a water pipe leading from the tank to the basin, and an
air pipe leading from the space in the waste pipe which is between the stench
traps of the injector D having its inner tube connected with the water tank and in
'communication with the water pipe and its outer tube in communication with the
.air pipe and the water pipe whereby the flow of water from the tank through the
injector is made to produce a partial vacuum in said space, the valve F, the
lever H, connected thereto and the cord I, substantially as specified.
Third. The combination with a water closet basin formed to constitute a stench
trap, a waste pipe or passage leading therefrom and so constructed as to form a
stench trap, a source of water, a pipe for conveying water to the basin, and an air
pipe leading from the space in the waste pipe or passage which is between the
stench traps, of an injector connected with the water pipe and the air pipe and
serving to produce a partial vacuum in said space by the flow of water through the
injector and a valve in said air pipe between said space and the injector substantially
as specified.
