Improvements in or relating to Water Closets.
ALFRED JULIUS BOULT of 323 High Holborn, in the County of Middlesex, M.I.M.E.
do hereby declare the nature of this 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 the invention is, first, to design a water tank or reservoir of the
requisite strength and capacity which will occupy the least possible space; and secondly
to arrange the supply and discharge pipes from the tank so that the tank may be
supplied with water from the ordinary house service, while its discharge pipe is large
enough to give a full volume of water to the closet and it consists, first, of a series
of small vertical cylinders connected to a horizontal cylinder, and secondly, of a three
way valve ease through which the tank may be fed with water from the ordinary house
service but through which the closet is supplied with a large body of water direct from
the tank the whole being arranged substantially as hereinafter more particularly
explained.
:
Figure 1 is a perspective view showing the improved tank and valve mechanism
connected to a closet.
Figure 2 is an enlarged sectional view of the tank and valve.
As it is necessary to make the tanks for water closets sufficiently strong to resist
the water pressure it is customary to make the tanks round and in all that I have seen
a single chamber only has been used, which must necessarily be of too large a diameter
to be sunk into the wall or placed behind the wainscoating.
By this invention I am able to make a tank which may be if necessary completely
hidden from view and which is nevertheless of sufficient capacity to supply the
requisite water to the closet.
A represents a series of vertical cylinders connected to and opening into the
horizontal cylinder B.

page_text: C is a three way valve case one branch of which is connected to the bottom of the
cylinder B another branch with the supply pipe D which is of the ordinary house
service size while the third branch connects with the discharge pipe E loading into
the closet.
It will he noticed that the branch connecting with the supply pipe D) is smaller than
the branches connecting with the cylinder B and discharge pipe E.
A doubled ended valve F is placed in the valve case C in which two valve seats a
and bare formed as shown; the valve seat a being in the branch connecting with the
supply pipe D while the valve seat is formed between the branch leading into the
cylinder B and the branch connecting with the discharge pipe E.
In Figure 2 the valve is shown seated upon the valve seat b. When in this position
communication is cut off between the cylinder Band discharge pipe E while the passage
between the supply pipe D and cylinder B is open.
Owing to the pressure of the water entering through the supply pipe D it is
necessary to supply force for the purpose of holding the valve in the position in
which it is indicated in Figure 2. This force may be secured in various ways, but in
Figure 1 I show an appropriate device for that purpose.
It consists of a crank G
pivoted on the frame H of the seat and one end of the crank designed to be in contact
with the end of the valve spindle f. Its other end is connected to a pivoted lever 1
connected with the seat in such a manner that when the party about to use the closet
is seated the arm of the crank G in contact with the valve spindle presses against
the said valve spindle so as to hold the valve F against the seat b which action holds
the other end of the valve clear of the valve seat a leaving the passage open for the
water to pass from the supply pipe D into the cylinders A and B.
As soon as the party rises from the seat the crank G no longer exerts sufficient force
upon the valve spindle to hold the valve in its closed position while the pressure of the
water entering through the supply pipe D forces the valve clear of the seat band
against the seat a thereby opening a clear passage way from the cylinders A B to the
discharge pipe E which conveys in a rapid manner the water contained in the
cylinders A and B to the closet.
Having now particularly described and ascertained the nature of the said invention
as communicated to me by my foreign correspondent and in what manner the same is
to be performed I declare that what I claim is :-
1. A water reservoir or tank composed of a series of cylinders A connected to and
leading into the cylinder B substantially as and for the purpose specified.
2. A three way valve case C formed substantially as shown and having the seats a
and formed in it in combination with a double ended valve F substantially as and
for the purpose specified.
3. A water reservoir or tank composed of a series of cylinders A connected to and
leading into the cylinder B in combination with a three way valve case C having a
small branch to connect with the supply pipe D and large branches to connect with
the cylinder Band discharge pipe E respectively the said branches being separated
by means of the double ended valve F seated alternately on the valve seats a and
substantially as and for the purpose specified.
4. A three way valve case formed substantially as shown and connected respec-
tively to the cylinder B supply pipe D and discharge pipe E a double ended valve F
designed to be seated alternately upon the valve seats a and b and provided with a
valve spindle in combination with a pivoted crank G and pivoted lever I arranged
substantially as and for the purpose specified.
