PROVISIONAL SPECIFICATION.
Improvements in Valve Apparatus for Waterclosets and other
Apparatus.
We, JAMES GRAY CONNELL, and JOHN GORDON, of 38 Saint Enoch Square, Glasgow,
in the County of Lanark, North Britain, Brassfounders, do hereby declare the nature
of this invention to be as follows, that is to say :-
Our said Invention comprises improved and simplified valve apparatus advan-
tageously applicable to waterclosets and also suitable other applications.
Our improved apparatus is applicable to waterclosets of various kinds, we however
prefer to arrange it in connection with a closet basin or receiver made of earthenware
or enamelled metal or other suitable material and formed with a discharge outlet at one
side such outlet communicating with a vertical passage at the side having in it a
main discharge valve which opens by the direct lifting action of the closet handle.
The main discharge valve is connected to the closet handle by two rods which extend
up through upper and lower guides, the upper guides being formed in a plate which
covers the top of the vertical side passage, and which has the water-supply valve box
formed on or fixed to its underside between the two rods. The water-supply valve is
made with one or more parts and opens by lifting, being raised when the closet handle
is drawn up by the upward pressure of the main discharge valve or a piece moving
with it on the valve spindle. The valve spindle projects down through a hole in
the bottom of the valve box for which no packing is required as any leakage
drops down the vertical passage. The water-supply valve seat and opening is in a
horizontal partition dividing the interior of the valve box into upper and lower
compartments. The water enters the upper compartment and when the valve is
open passes from the lower compartment to the closet basin. When the pressure
of the water supply is not great the valve used is a single disk or button at the
upper end of the valve spindle, but when the pressure is great a small central
button is combined with an annular valve of larger size or with more than one
annular valve of graduated sizes; and the spindle is constructed to first open the
small central button so as to relieve the pressure and as it continues to rise to open
the annular valve afterwards or when there are more than one annular valve to
open them in succession. The lower compartment of the valve box is formed with
a cylindrical or other conveniently shaped space at its lower part and a plunger or
block on the valve spindle is arranged to work in this space for the purpose of pre-
venting the valve from closing suddenly and, in the application to a watercloset, to
provide an after flush. When the valve spindle is raised to open the valve, water
gets into the space under the plunger and when the handle is let go the plunger
has to force the water out of the space whilst the valve is closing, the duration
of the closing action depending on the greater or less clearance provided for the
passage of the water past the plunger.

Improvements in Valve Apparatus for Waterclosets and other
Apparatus.
We, JAMES GRAY CONNELL, and JOHN GORDON, of 38 Saint Enoch Square,
Glasgow, in the County of Lanark, North Britain, Brassfounders, do hereby declare
the nature of this invention and in what manner the same is to be performed,
Pin d

page_text: to be particularly described and ascertained in and by the following statement, that is
to say:
Our said Invention comprises improved and simplified valve apparatus advan-
tageously applicable to waterclosets and also suitable for other applications.
Our improved apparatus is applicable to waterclosets of various kinds, we how-
ever prefer to arrange it in connection with a closet basin or receiver made of
earthenware or enamelled metal or other suitable material and formed with a
discharge outlet at one side, such outlet communicating with a vertical passage
at the side having in it a main discharge valve which opens by the direct lifting
action of the closet handle. The water supply valve is opened by means of a
spindle projecting down through a hole in the bottom of the valve box; and the
valve seat and opening is in a horizontal partition dividing the interior of the valve
box into upper and lower compartments, the water entering the upper compartment,
and when the valve is open, passing from the lower compartment to the basin.
When the pressure of the water supply is not great the valve used is a single disk
or button at the upper end of the valve spindle, but when the pressure is great a
small central button or valve is combined with an annular valve of larger size, or
with more than one annular valve of graduated sizes; and the spindle is constructed
to first open the small central button so as to relieve the pressure, and as it con-
tinues to rise, to open the annular valve afterwards, or when there are more than
one annular valve to open them in succession. A block or piston moving with the
valve works in a cylindrical shell which may be either below or above the valve,
and prevents the valve from closing suddenly, also, in the case of a watercloset,
providing an after flush.
And in order that our said Invention and the manner of performing the same
may be properly understood we hereunto append a sheet of explanatory drawings
to be hereinafter referred to and representing valve apparatus as made with our
improvements.
Figure, 1, of the drawing is a vertical section of a watercloset basin and its
valve apparatus; and figure, 2, is a horizontal section showing the water supply
inlet into the valve box and the passage by which the water passes thence to the
basin. Figure, 3, is an enlarged vertical section of the water supply valve apparatus
as slightly modified from what is shown in figure, 1. In these drawings the same
reference numerals are used to mark the same or like parts wherever they are
repeated.
In figure, 1, our improved apparatus is shown as fitted to a watercloset basin, 4,
made of earthenware and in one piece with a base, 5, and a lateral vertical passage, 6, 7.
Between the upper and lower parts, 6, 7, of the lateral vertical passage there is a
seat, 8, for a main discharge valvo, 9, which is opened by the direct lifting action
of the closet handle, 10, when drawn up. The main discharge valve, 9, is connected
to the closet handle, 10, by two rods, 11, which exteud up through guide holes
formed in a plate, 12, which covers the top of the vertical side passage, 6, 7, and
which has the water-supply valve box, 13, formed on or fixed to its under side,
partly between the two rods, 11. The valve is in this example in two parts, an
annular valve, 14, and a small central valve, 15, which latter closes down upon
the central aperture of the annular valve, 14, whilst the annular valve itself closes
down upon a valve seat or opening in a horizontal diaphragm, 16, dividing the
interior of the valve box into upper and lower compartments, 17, 18. The water
inlet, 19, communicates with the upper compartment, 17, and an opening in the side
of the lower compartment, 18, leads by a passage, 20, in the valve box, into a
passage, 21, formed at the side of the closet basin. The passage, 21, communicates
with a hollow rim, 22, from which the water issues by a number of holes ; and
there is also an after-flush box, 23, which receives water from the passage, 21,
and allows it to pass slowly into the basin through a small hole at its bottom.
The valves, 14, 15, are opened by being lifted by means of a valve spindle, 24,
which projects down through a hole in the bottom of the valve box, 13, for which
hole no packing is required as any leakage drops down the vertical passage, 6.

page_text: The valve spindle, 24, is made with guide feathers, 25, which move through the
valve opening in the diaphragm, 16; and the top of the spindle extends through
the central aperture in the annular valve, 14, to enable it to act on the small upper
central valve, 15. When the closet handle, 10, is drawn up, a stud or nut, 26, on
the main discharge valve, 9, raises up the valve spindle, 24, and the upper end of
the spindle first lifts the small valve, 15, which relieves the pressure and imme-
diately afterwards the feathers, 25, reach the annular valve, 14, and lift it. In
the example shown in figure, 1, the lower compartment, 18, of the valve box is
formed with a cylindrical space at its lower part and a plunger or block, 27, on
the valve spindle, 24, is arranged to work in this space for the purpose of prevent-
ing the valve from closing suddenly, and to contribute to the after flush. When
the valve spindle, 24, is raised to open the valvo, water gets into the space under
the plunger, 27, and when the handle is let go the plunger has to force the water out
of the space whilst the valve is closing, the duration of the closing action depending
on the greater or less clearance provided for the passage of the water past the
plunger.
In the modification shown in figure, 3, instead of the plunger (27) fixed on the
valve spindle, 24, and working in the lower compartment, 18, there is a plunger or
piston, 28, fitted to work in the upper part, 29, of the upper compartment, 17; and
this piston is also made to serve for closing the central aperture in the annular
valve, 14, instead of a small separate piece or valve, (15). The actual closing part
is a rubber washer, 30, placed in a recess in the piston, 28, and which when the
piston is moved up by the valve spindle, 24, bends down and uncovers holes made
through the piston thereby allowing water to pass freely from the upper space, 29.
Afterwards when the piston descends by its weight, the rubber washer, 30, closes the
holes and retards the descent whilst the water returns to the upper side either
past the circumference of the piston or through a very small hole provided for the
purpose.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The combining of the parts of valve apparatus for waterclosets in the improved
manner substantially as hereinbefore described with reference to figures, 1, and 2,
of the accompanying drawings.
2. The combining of the parts of valve apparatus for waterclosets in the improved
manner substantially as herein before described with the modification shown in
figure, 3, of the accompanying drawings.
3.-In valve apparatus for various purposes, the combination of two or more
valves arranged to open against pressure and made of graduated sizes each excepting
the largest having its seat on a central aperture of the next larger valve, and the
spindle being made with correspondingly graduated parts to open the smallest valve
first and the others in the order of their increased sizes substantially as herein before
described.
4. In valve apparatus for various purposes the combination of a plunger or piston
arranged and operating as hereinbefore described with parts such as those which are
referred to in the next preceding claim.
