A NEW OR IMPROVED AUTOMATIC APPARATUS FOR PREVENTING WASTE OF
WATER IN WATER CLOSETS."
My Invention relates to the application of a new or improved automatic apparatus
to water closets for preventing the waste of water therein arising from carelessness
or derangement of the apparatus in present use.
It consists in fixing in the supply pipe to the closet pan a valve box containing
a double acting check valve, the stem of which is enlarged at its upper portion so
as to present a larger area than the valve. The outer end of this enlarged portion
of the valve stem works through a stuffing box and butts against the underside of
the front part of the water closet seat which is movable and hinged at the back.
Between the two valve seats is a pipe leading to within a short distance of the
bottom of an air vessel placed in any convenient situation.
On pressure being applied to the water closet seat, the double acting check valve
is forced by the entering water on to one of the valve seats so as to stop the passage
of the water from the supply pipe to the closet pan, at the same time allowing it to
enter the air vessel where it more or less accumulates and compresses the air
contained therein.

page_text: On the pressure being removed from the water closet seat the valve rises, and
coming on to the other valve seat closes the supply pipe, and the compressed air
forces the water contained in the air vessel through the open valve seat into the
closet pan, which is thereby flushed.
By the friction produced between the stuffing box and the enlarged portion of
the valve stem, the valve is prevented from rising too quickly, and concussion in
the pipes is thereby avoided.
By this arrangement only a limited quantity of water is allowed to pass through
the pan at one time, the supply pipe being normally kept closed until the water is
required for use.
The great waste of water which frequently occurs by omitting to close the plug
or valve as usually applied to water closets, is thereby obviated.

"A NEW OR IMPROVED AUTOMATIC APPARATUS FOR PREVENTING WASTE OF
WATER IN WATER CLOSETS."
My Invention relates to the application of a new or improved automatic apparatus
to water closets for preventing the waste of water therein, arising from carelessness
or derangement of the apparatus in present use.
It consists in fixing in the supply pipe to the closet pan a valve box containing a
double acting check valve, the stem of which is enlarged at its upper portion so as
to present a larger area than the valve.
The outer end of this enlarged portion of the valve stem works through a stuffing
box and butts against the underside of the front part of the water closet seat
which is moveable and hinged at the back. Between the two valve seats is a pipe
leading to within a short distance of the bottom of an air vessel placed in any
convenient situation.
On pressure being applied to the water closet seat the double acting check valve
is forced on to one of the valve seats so as to stop the passage of the water from
the supply pipe to the closet pan, at the same time allowing it to enter the air
vessel, where it more or less accumulates and compresses the air contained therein.
On the pressure being removed from the water closet seat the valve rises, and
coming on to the other valve seat closes the supply pipe, and the compressed air
forces the water contained in the air vessel through the open valve seat into the
closet pan, which is thereby flushed.
And in order that my said Invention may be well understood I shall now proceed
more particularly to describe the same, and for that purpose shall refer to the
accompanying Sheet of Drawings, like letters of reference indicating corresponding
parts in all the Figures.
Fig. 1 is a sectional elevation of my improved automatic apparatus, which consists
of a valve box A fixed in the supply pipe B to the closet pan C, and containing a
double acting check valve D, E, the stem F of which is formed at its upper end
with a cylindrical enlarged portion G which works through a gland and stuffing
box H in the top part of the valve box A, and presents a larger area at its under
side than the valve D.
The outer end of the enlarged part G butts against the underside of the front
part of the water closet seat I which is moveable and hinged at the back as shown.
Between the seats of the valve D, E, is a pipe J leading from the valve box A to
within a short distance of the bottom of an air vessel K located as shown, or in
any other convenient position. L is the pipe leading from below the valve E to the
closet pan C.
Upon depressing the closet seat I the enlarged portion G of the valve stem F is
forced downwards, and carrying with it the valve D away from its seat opens com-
munication between the pipes B and J; the valve E at the same time closing pipe L
as shown.
By this means the water from the supply pipe B passes the valve D through the
pipe J into the air vessel K where it more or less accumulates and compresses the
air contained therein.
On the pressure being removed from the water closet seat I the water from the
supply pipe B acting upon the superior area of the enlarged part G on the stem F
moves the valve D on to its seat and so closes communication between the pipes B
and J, at the same time moving valve E away from its seat so as to open communi-
cation between the pipes J and L, when the compressed air above the water in the
air vessel K forces the water contained in the latter through the pipes J and L
into the closet pan C, which is thereby flushed as required.

page_text: By the friction produced between the stuffing box H and the enlarged portion G
of the valve stem F, the valve D is prevented from rising too quickly, and concussion
in the pipes is thereby obviated.
By this arrangement only a limited quantity of water is allowed to pass through
the pan C at one time, the supply pipe B being normally kept closed until the water
is required for use.
The great waste of water which frequently occurs by omitting to close the plug
or valve as usually applied to water closets is thereby obviated.
Having now described and particularly ascertained the nature of my said Inven-
tion, and the manner in which the same is or may be used or carried into effect, I
would observe in conclusion that what I consider novel and original and therefore
claim as the Invention secured to me by the herein before in part recited Letters
Patent is,-
The application and use of double acting check valve in combination with an air
vessel to water closets, substantially as and for the purpose hereinbefore described,
and illustrated by the accompanying Drawing.
In witness whereof, I, the said Hermann Ernst Thomas Goodson, have here-
unto set my hand and seal, this Twenty seventh day of May, in the year
of our Lord One thousand eight hundred and seventy nine.
