Improvements"in and connected with Water Olosets.
We, JOHN DEAN, of Market Place, Middleton, Plumber, and GEORGE HILTON
SMITH, of Irk View, Rhodes, near Middleton, Machinist, both in the County of
Lancaster, do hereby declare the nature of this invention to be as follows :--
This invention relates to improvements in and connected with water closets,
which improvements are chiefly applicable in conjunction with the " charging
vessel" described in co-applicants Patent, No. 3418, dated March, 4th, 1890, and
have for their object to render the flushing more reliable, economical, & waste
preventing, as well as to reduce the movement of the closet seat where the flushing
is performed through its action.
To this end our improvements consist principally in the use of a diaphragm valve
of suitable construction in conjunction with the charging vessel aforesaid for the
purpose of controlling the flushing of the closet basin.
In carrying out our improvements, we employ an ordinary push tap to cut off
and establish communication between the main and the said charging vessel, which
is brought in communication with the said diaphragm valve by means of a lever,
one end of which bears against the stem or spindle of the said push valve and the
other being connected to the spindle of the diaphragm valve furnished with a
weight. In, or on, about the middle of the said lever, is rendered adjustable a rod,
suitably guided and bearing against a rubber cushion fitted into or onto the
underside of the hinged closet seat. At the back of the latter, is mounted between
centres a shaft, having at one end a short lever bearing against another short
lever, fixed on the spindle of the said diaphragm valve, and near the middle thereof
a short lever or finger bearing against the stem of a push tap employed in connection
with the syphon pipe of the said charging vessel and the closet basin.
In order to prevent the said diaphragm valve from unduly operating the push
tap, which is in communication with the closet basin and charging vessel and thus
cause a waste of water, we employ in connection with the said diaphragm valve, a
locking device, consisting of a weighted lever, arranged to oscillate on a stud and
formed with a leg, which lever is connected to a rod suitably guided and operated
upon by the closet seat, so that on the latter being depressed the said leg is
catised to bear against the stem of the spindle of the said diaphragm valve anc
thus lock it to its seat.
.
A-modification of our invention consists in dispensing with the push tap, which
is in communication with the charging vessel and the closet basin and with the
mechanism employed between the same and the said diaphragm valve and bringing
the latter, by means of a pipe in direct communication with the closet basin and
the closet seat with the 'diaphragm valve spindle.

COMPLETE SPECIFICATION.
Improvements in and connected with Water Closets.
We, JOHN DEAN, of Market Place, Middleton, Plumber, and GEORGE HILTON
SMITH, of Irk View, Rhodes, near Middleton, 'Machinist, both in the County of
Lancaster, 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 :-
This invention relates to improvements in and connected with water closets,
which improvements are chiefly applicable in conjunction with the "charging
vessel" described in cc-applicant's Patent, No. 3418, dated March, 4th, 1890,.and
have for their object to render the flushing more reliable, economical, waste
preventing, as well as to reduce the movement of the closet seat where the
flushing is performed through its action.
To this end our improvements consist principally in the use of a diaphragm
valve of suitable construction in conjunction with the charging vessel aforesaid for
the purpose of controlling the flushing of the closet basin.
And in order that our invention may be more fully understood we have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Figs. 1, 4 & 5 are sectional elevations of our improved water closet. Fig. 2 is a
plan and Fig. 3 a front view of the water charging vessel of Fig. 1, and Fig. 6 a
plan of Fig. 5. Fig. 7 is a sectional side view and Fig. 8 a front view of a
modification of our invention.
In carrying out our invention and referring to Figs. 1, 2, 3 & 4, we employ a
closed water charging vessel a, which may form part of the closet basin b, see
Figs. 5 & 6, or may be placed behind the same in existing closets, as shown in
Figs. 1, 2, 3 & 4. This vessel a near its bottom is connected to an inlet pipe c
leading to the water main and having a push tap d which serves to establish or
cut off communication between the water main and charging vessel a.
The push
tap d is formed with a long stem d' on which rests a lever e, furnished with a rod e'
vertically guided. On the closet being used, the seat f depresses the rod e', lever e
and stem d¹ and thus opens the push tap d and establishes communication between
the water main and charging vessel.a, which communication is cut off the moment
the closet seat fis released. The latter is raised to its former position, partly by the
pressure of water exerted on the push tap d and partly by a rubber cushion f
fitted between the joint of the closet seat f. Inside the vessel a is employed a
syphon pipe g which is in communication with a push tap and the latter with
the flush inlet i of the closest basin b. The push tap h is operated by means of
a diaphragm valve k supported by a seat in communication with the charging
vessel a. The diaphragm of the valve k has attached a stem k to which is
connected a lever e, so that on the rod e¹ being depressed by the closet seat f the
diaphragm of the valve k is kept tight against its seat, whilst when released it lift<<
the stem . The latter bears against a lever fixed to a spindle m suitably
mounted, which has attached another lever ', bearing against the stem ¹ of the
push tap h. On the rod e' opening the push tap d and the water from the main
rushing into the charging vessel a through pipe c at full pressure, the air in the
top portion of the charging vessel a is compressed thereby and thus forms an elastic
air cushion n. When the seat/' is released, the pressure upon the push tap d and
diaphragm of the valve k is removed, the push tap d closed and the air cushion n
permitted to expand and force the water against the diaphragm of the valve k
thus raising it. The stem ¹ of the latter then in its turn exerts a pressure on the
lever which rocks the spindle m and by means of the lever depresses the stem /'
of the push tap h and thus opens it. The air cushion n in the charging vessel a

page_text: is then permitted to expand and will force the water through the syphon pipe g.
and push tap h, into the closet basin b.
In order to prevent the diaphragm of the valve k and its stem from unduly
operating the push tap hand thus cause a waste of water, we employ in connection
therewith, a locking device, consisting of a weighted lever o, arranged to oscillate
on a stud of carried by an arm o³ and formed with a leg o', which lever o is connected
to a rod o suitably guided and operated upon by the closet seat f, so that on the
latter being depressed the leg of is caused to bear against the stem of the
diaphragm valve k and thus lock it to its seat.
An alternative arrangement, see Figs. 7 & 8, consists in employing a rocking.
lever p suitably mounted, one end of which is furnished with a rod p² operated
upon by the closet seat fand the other end being adapted to be placed between the
lever and the end of the casing of the valve h and thus take the pressure of the
lever off the stem h¹ of the push tap h when the closet is not in use.
If deemed necessary the rocking levers 1, and their connections, the diaphragm
valve k, push tap and syphon tap g may be dispensed with and in lieu of the
push tap h, a diaphragm valve r employed, see Fig. 4, which is in communication
with the lower part of the charging vessel a and with the closet basin b by means of
pipes leading from the latter to the diaphragm valve r. In this case there is also
a push tap d employed, in communication with the water main and charging vessel a
which is operated by the closet seat f, through the medium of a rod e, having
attached a lever e bearing against the stem d of the push tap d. When the closet is
in use the lever e presses against the stem of the diaphragm valve r and thus the
latter to its seat, which cuts off communication between the charging vessel a and
closet basin 6 whilst on the closet seat being released the push tap d closes and the
diaphragm valve r opens, which permits the air cushion n in the charging vessel a to.
expand, raise the diaphragm of the valver off its seat and force the water through
pipes into the closet basin b.
When forming the charging vessel a part of the closet basin b, see Figs. 5 & 6, a
syphon pipe is also used in the charging vessel a, but in communication with a
diaphragm flush valve r, its diaphragm being pressed to its seat, under normal
conditions, by means of a spring. After the closet seat has been depressed and
thus the push tap d opened, the diaphragm of the flush valve r is firmly retained on its
seat by the pressure exerted on its stem by the closet seat f, whilst when the latter
is released, the air cushion n in the charging vessel a is permitted to expand and force
the water through the syphon pipe g and inlet i into the closet basin b, the pressure of
the spring being thereby overcome and the diaphragm of the valve moved off
its seat.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed, we declare that what we
claim, is
"In water closets."
