PROVISIONAL SPECIFICATION.
Improvements in and connected with Cisterns, Sinks, Baths and

I, JOHN SHANKS, of Tubal Works, Barrhead, in the County of Renfrew, North
Britain, Sanitary Engineer, do hereby declare the nature of this Invention to be
as follows, that is to say:-
My said Invention has for its object to improve the construction of various
water supply and discharge details of cisterns, and other domestic vessels.
The improved apparatus comprises parts in connection with a ball float designed
The.
to prevent or considerably diminish noise when a cistern is being filled.
water inlet is directed upwards through the bottom of a cup, and the valve which
closes downwards is made with a flange to spread the water. The float lever
acts on the valve by an eccentric projection at its fulcrum, the valve being guided
and being made with a stem extending upwards to a position in which the float
lever can be conveniently arranged to act on it. The water may overflow from
the upper edge of the cup, by preference however the cup is made with an over-
flow outlet near the top and with a pipe extending down to the lower part of
the cistern.
A second improvement relates to siphonal discharge apparatus within the
cistern. The siphon consists of a pipe having three legs combined with a bell
movable by a lever. The entrance to the pipe is flared and the part of the bell
above is shaped to dip into the flared part to diminish the quantity of air to be
removed when siphoning takes place. The siphon pipe is made with a pear-like
enlargement at or near where it passes through the bottom of the cistern.
Further improvements apply to the connection of the downlet pipe to the cistern
or of a sink or bath or the like to a waste or discharge pipe. A downward pro-
jection is formed around the orifice in the bottom of the cistern or other vessel,
and a ring of rubber or other suitable compressible material is placed around
the projection. The end of the downlet or discharge pipe has formed on it a
cone or a flat or curved flange, which is tightened up against the compressible
ring by a metal ring in one or two parts bolted to the bottom of the cistern or
vessel or to each other. In another modification the compressible ring is applied
outside of the flange on the pipe end, the ring bolted to the cistern or vessel
bottom being shaped to bear on the compressible ring. In further modifications
no compressible ring is employed, the flange on the pipe end being tightly pressed
up against the cistern or vessel bottom by means of the bolted-on ring. One
or more narrow annular projections may be formed on the cistern or vessel bottom,
corresponding depressions being made in the holding-up ring, to insure tightness
in the joint.

COMPLETE SITUITUATION.
'Improvements in and connected with Cisterns, Sinks, Baths, and
the like."
I, JOHN SILANKS, of Tubal Works, Barrhead, in the County of Renfrew, North
Britain, Sanitary Engineer, 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 has for its object to improve the construction of various
water supply and discharge details of cisterns, and other domestic vessels.
1
Various modifications of apparatus as made according to my Invention are
shown on an accompanying sheet of explanatory drawings, figure, 1, thereof being
a vertical section of one modification of the improved apparatus.
Figures, 2, 3, 4, 5, 6, 7, and 8, are vertical sections of separate modifications of
a detail of the improved apparatus. In these drawings the samé reference letters
and numerals are used to mark the same or like parts wherever they are repeated.
As shown in figure, 1, of the drawings the improved apparatus comprises parts
in connection with a ball float, A, designed to prevent or considerably diminish
noise when the cistern, B, is being filled. The water inlet, C, is directed upwards
through openings, F, in the bottom of a cup, D, formed in the same casting with
(or it might be in a separate piece fixed to) the cistern, B, and the valve, E, which
closes downwards is made with a flange to spread the water. The float lever, G,
acts on the valve, E, by an eccentric projection, G1, at its fulcrum, H, which
is a spindle extending across the cup, D, the valve being made with a stem, E1,
which works in a guide, D 1, in the cup. The water may overflow from the upper
edge of the cup, D, by preference however the cup is made with an overflow
outlet, D2, near the top, with a pipe, D3, extending down from it to the lower
part of the cistern..
A second improvement relates to the siphonal discharge apparatus within the
cistern, B. The siphon, J, consists of a pipe having three legs combined with
a bell, J1, movable by a lever, J2. The entrance to the pipe or siphon, J, is
flared and the part of the bell, J 1, above it is shaped to dip into the flared part
to diminish the quantity of air to be removed when siphoning takes place. The
siphon pipe, J, is made with a pear-like enlargement, J3, at or near where it
passes through the bottom of the cistern, B.
Further improvements apply to the joint connecting the downlet pipe to the
cistern, B, or the waste or discharge pipe to a sink or bath or the like. A down-
ward projection, L, is formed around the orifice, L1, in the bottom of the cistern
or other vessel, B, as shown in figures, 2, 3, 4, 5, 6, 7, and 8, and a ring, L2, of
rubber or other suitable comprèssible material is placed around the projection_as
shown in figures, 2, 3, and 4. The end of the downlet or discharge pipe, K 1,
has formed on it a cone, K2 (figure, 2) or a flat flange, K2 (figure, 3) or a curved
flange (figure, 5) or with an enlargement, K2 (figure, 4) which is tightened up
against the compressible ring, L2, by a metal ring, L3, made in one piece and
bolted to the bottom of the cistern or vessel, B (as in figures, 2, and 3) or in
two parts which are bolted to each other (as in figure, 4). In the modification
shown in figure, 5, the compressible ring, L2, is applied outside of the flange, K 2.
on the pipe end, the ring, L3, bolted to the cistern or vessel bottom being shaped
to bear on the compressible ring, L2. In further modifications, shown in
figures, 6, 7, and 8, no compressible ring (L2) is employed the flange, K2, on
the pipe, K1, being tightly pressed up against the cistern or vessel bottom by
means of the bolted-on ring, L3, The pipe end may be made with a conical

page_text: flange, K2, as in figure, 6, the bolted-on ring, L3, and downward projection, L,
being formed as counterparts to suit; or one or more narrow annular projec-
tions, L, may be formed on the cistern or vessel bottom (as in figures, 7, and 8)
corresponding depressions being made in the downlet-pipe flanges, K 2, and hold-
ing-up rings, L3, to insure tightness in the joints.
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 and connected with cisterns, or other vessels, providing a water inlet
directed upwards through the bottom of a cup and having a valve closing down-
wards made with a flange to spread the water, and with a central stem acted on
by an eccentric projection on a float lever near its fulcrum, the water overflowing
at the upper edge of the cup either directly into the cistern or vessel or into an
outlet pipe leading to the bottom of the vessel substantially as and for the purposes
herein before described with reference to figure, 1, of the accompanying drawings.
2. In and connected with cisterns, combining a siphon having three legs with
a bell movable by a lever connected to the closet handle and having a part shaped
to dip into the upper flared end of the siphon, which at its other end is connected
to the downlet pipe substantially as and for the purposes hereinbefore described
with reference to figure, 1, of the accompanying drawings.
3. Forming round the discharge orifice of a water-supply cistern or like vessel
an external annular projection round and between which and a suitably shaped
part of the discharge pipe is placed a ring of compressible material, the discharge
pipe and compressible ring being forced against the annular projection by a metal
ring substantially as hereinbefore described with reference to figures; 2, 3, and 4,
of the accompanying drawings.
4. Forming round the discharge orifice of a water-supply cistern or like vessel
an external annular projection against which a suitably shaped part of the dis-
charge pipe bears, the discharge pipe being pressed against the annular projection
by a metal ring between which and the pipe flange there is a ring of compressible
material substantially as hereinbefore described with reference to figure, 5, of the
accompanying drawings.
5. Forming round the discharge orifice of a water-supply cistern, sink, bath,
or the like, a downwardly projecting conical part against which the upper conical
end of the discharge pipe is. pressed by a counterpart metal ring bolted to the
bottom of the cistern or like vessel substantially as hereinbefore described with
reference to figure, 6, of the accompanying drawings.
6. Forming round the discharge orifice of a water-supply cistern, sink, bath,
or the like, one or more external annular projections against which a counter-
part flanged part of the discharge pipe is pressed by a counterpart metal ring
bolted to the bottom of the cistern or like vessel substantially as hereinbefore
described with reference to figures, 7, and 8, of the accompanying drawings.
