page_text: Improvements in Water Supply Valves for Water Closets.
I, JAMES GRAY CONNELL, of 44, Saint Enoch Square, in the County of Glasgow,
North Britain, Brassfounder, do hereby declare the nature of this invention
to be as follows, that is to say:-
My said invention comprises an improved and simple construction of water
supply valve which with one action yields a main flush and an after flush to a
watercloset and does not shut off the water abruptly.
In the improved apparatus the valve piece, which when open admits water to
the closet, closes down upon a valve seat in the lower part of the valve box. The
valve piece has formed on its upper part a piston fitted to work in the cylindrical
interior of an inverted cup. In the valve piece there is formed a central opening
adapted to be closed by a small valve formed or fixed on the upper end of a
spindle extending downwards, the opening movement of this valve being limited
by a stop. When the valve piece is closed the inverted cup is full of water the
valve piston being at the lower end of it.
When the closet handle is raised to open the main discharge valve a part moved
by it pushes up the valve spindle. By this action the small valve is first opened,
allowing the water to get out of the inverted cup, and then the valve piece and
cup are both raised, allowing the main flush to enter the closet basin. In the
action the valve piston is moved up to the top of the inverted cup, and when the
closet handle is let go, the cup descends until its bottom edge rests on an annular
surface encircling the valve seat, the valve piece and piston following but at a
slow rate depending on the slow passage of water into the cup past the piston
which is not quite tight, or through a small hole. The bottom edge of the cup
is made with a few small notches through which water can pass after the cup
has descended, the water passing in this way whilst the valve piece is slowly
closing forming the after flush for the closet basin.
In another modification the cup is fixed to or formed on the valve piece, a few
small holes being formed through its lower part.

page_text: I, JAMES GRAY CONNELL, of 44, Saint Enoch Square, in the County of Glasgow,
North Britain, Brassfounder, 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, that is to say: -
My said invention comprises an improved and simple construction of water
supply valve which with one action yields a main flush and an after flush to a
watercloset and does not shut off the water abruptly.
In the improved apparatus the valve piece. which when open admits water 10
the closet, closes down upon a valve seat in the lower part of the valve box. The
valve piece has formed on its upper part a piston fitted to work loosely in the
cylindrical interior of an inverted cup and having holes in its upper surface. In
the valve piece there is formed a central opening adapted to be closed by a small
valve formed or fixed on the upper end of a spindle the opening movement of this
valve being limited by a stop. Holes or notches are formed round the side and
bottom edge of the inverted cup.
In another modification the cup is fixed to or formed on the valve piece, holes
being formed through it as in the modification hereinbefore described.
And in order that my said invention and the manner of performing the same
may be properly understood I hereunto append a sheet of explanatory drawings
to be hereinafter referred to and showing two modifications of my improvements.
Figures, 1, 2, 3, of the drawings are vertical sections of one modification of my
improved water supply valve showing the parts in different positions in the
valve box. Figure, 4, is a vertical section of a second modification of the valve
but without the valve box. In these drawings the same reference letters are
used to mark the same or like parts wherever they are repeated.
In the improved apparatus shown in Figures, 1, 2, and 3, the valve piece, A,
which when open admits water to the closet (not shown) closes down upon a
valve seat, B in the lower part of the valve box, C. This valve box is made with
an inlet, D, and an outlet, E, and has at its upper end a screwed-in cover, F,
permitting of the insertion or removal of the moving parts. The valve piece, A,
is a rubber disc held in position by a nut, G, screwed to the under side of a hollow
piston, H, this piston being fitted to work loosely in the cylindrical interior of
an inverted cup, J, and having holes, K, through its upper end. The inverted
cup, J, works loosely in the upper part of the valve box, C, and it has holes formed
through its side at L, and also round its lower part at M. In the interior of
the piston, H, there is a small valve, N, formed or fixed on the upper end of a
spindle, P, extending downwards, the opening movement of this valve being limited
by a stop, Q, on the underside of the upper end of the piston. The spindle, P',
is made with longitudinal grooves, R, so as to form passages through the valve
piece which are closed by the small valve, N. When the valve, A, is closed, as
shown in Figure, 1, the upper end of the valve box, C, the inverted cup, J, and
the piston, H, are full of water, the water having found its way past the cup to
the upper end of the valve box and through holes, L, and K, to the interior of
the cup and piston.
When the closet handle is raised to open the main discharge valve a part moved
by it pushes up the valve spindle, P. By this action the small valve, N, is first
opened allowing water to get out of the inverted cup, J, and piston, H, through
the holes, K, in the upper end of the piston and through the passages, R. On
the continued upward movement of the spindle, P, the piston, H, and valve, A,
are raised until the upper end of the piston bears on the upper end of the inverted
cup, J, as shown in Figure, 2, in which position the water above the cup can

page_text: escape through the holes, L, in the side of the cup to the discharge
outlet, E. The parts are then raised to the position shown in
Figures 3, allowing the main flush to pass to the outlet, E. When
the closet handle is let go the parts descending again first assume the
position shown in Figure, 2, in which position the bottom edge of the cup, J,
rests on an annular surface encircling the valve seat, B, the valve piece, A, and
piston, H, following but at a slow rate depending on the slow passage of water
through the holes, L, into the cup, J, past the piston, H, which is not quite tight.
Water passes through the holes, M, round the lower part of the cup, J, whilst
the parts are in the position shown in Figure, 2, the water passing in this way
whilst the valve piece, A, and piston, H, are slowly closing allowing an after
flush to pass to the closet basin. When the valve piece, A, reaches its seat, B,
the small valve, N, will also close the central opening through the valve piece
and the parts will again have assumed the position shown in Figure, 1. In some
cases holes may be formed in the top of the cup, J, instead of the holes, L, in
the sides.
In the modification shown in Figure, 4, the valve, A, is fixed on the underside
of the cup, J, instead of being on the piston, H, as in the modification herein before
described. The piston, H, is made with an open top and an additional small
valve, S, is fixed on the spindle, P, below the piston and the valve, N, is normally
off its seat. When the spindle, P, is first moved upwards the valve, S, rises and
the water in the cup, J, and piston, H, escapes through the central opening in the
valve piece. Then on the piston, H, reaching the top of the cup, J, the parts are
raised and the water in the upper part of the valve box (not shown) escapes
through the holes, L, exactly as in the modification herein before described. On
the release of the spindle, P, the parts fall until the valve, A, reaches its seat (B)
then the flushing water passes through the holes, M, during the slow descent of
the piston H, the small valve, N, being then temporarily on its seat and holding
up the valve, S, to allow the water to pass through the central opening in the
valve piece. On the piston, H, reaching the bottom of its stroke the valve, S,
will have closed and the valve, N, opened and the water which was retarding the
descent of the piston will have found its way from the holes, L, past the piston
into the cup, J.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a water supply valve for waterclosets a valve piece attached to a piston
fitted to work loosely in the interior of an inverted cup and having holes in its
upper surface the valve piece having a central opening adapted to be closed by
a small valve on the upper end of a grooved spindle and holes being formed in
the side or upper end and bottom edge of the cup, the parts being arranged and
operating substantially as and for the purposes hereinbefore described with
reference to Figures 1, 2, and 3, of the accompanying drawings.
2. In a water supply valve for waterclosets a valve piece on the underside of
a cup having holes through it and a piston working loosely in its interior the
valve piece having a central opening through which extends a grooved spindle on
which are two small valves one beneath and the other in the interior of the
piston, the parts being arranged and operating substantially as and for the
purposes herein before described with reference to Figure, 4, of the accompanying
drawings.
