PROVISIONAL SPECIFICATION.
Improvements in Supply and Discharge Valves for Water-
service Apparatus.
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 comprises certain improvements in supply and discharge valves
for water service apparatus, my objects being to prevent or diminish noise with float
lever and other supply cocks, to combine the parts of such cocks in a better manner,
and to diminish waste of water in connection with discharge valves of baths, basins,
and analogous apparatus.
In carrying out my invention I make the body of a supply cock with an enlarge-
ment at the inlet, and place in such enlargement one or more perforated diaphragms
as a device for diminishing noise; and instead of or in addition to this internal device
I form an enlargement on the discharge nozzle of the cock and place one or more
perforated diaphragms therein, or I form in the discharge nozzle a conical annular or
other narrow discharge passage or orifice. I make the closing detail or valve of a
disk or button-like form on a plunger fitting the cavity in which it works; and in a
forked part of the plunger I fit an antifriction roller to be acted on by a cam formed
on the float lever.
For a bath, basin, or other vessel I employ a discharge or waste valve working at
the bottom of a vertical pipe or passage at one end or side of the vessel, the valve
being fixed or formed at the bottom of a tube which in existing arrangements of the
kind extends upwards in the pipe or passage to serve as an overflow passage. In
existing arrangements the vertical pipe or passage is always filled with water as high
as the level of the water in the bath or vessel and the water thus filling the pipe or
passage is wasted. By my invention I make the valve with an additional part which
when the mouth of the waste pipe is closed also closes the bottom of the vertical pipe
or passage and prevents the water from getting up into it. The additional part may
be a rubber or other flange closing down on a seat just above the lateral inlet from
the bottom of the bath or vessel into the valve chamber; or it may be a rolling
packing ring of rubber inserted between a cylindrical part of the valve piece and a
cylindrical part formed in the pipe or passage. The valve piece is made with a
passage through it and a tube may extend up from it as before for the overflow, or it
may he without a tube or have a short one. A separate overflow outlet is provided at
a suitable height in the end or side of the bath or vessel and communicates by a
nozzle with the tube or passage through the valve piece.

COMPLETE SPECIFICATION.
Improvements in Supply and Discharge Valves for Water-
service Apparatus.
I, JOH
SHANKS, 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 comprises certain improvements in supply and discharge valves
for water service apparatus, my objects being to prevent or diminish noise with float

page_text: lever and other supply cocks, to combine the parts of such cocks in a better manner:
and to diminish waste of water in connection with discharge valves of baths, basins,
and analogous apparatus.
Examples of my improved valves are shown on two accompanying sheets of
explanatory drawings, Figure, 1, on Sheet, 1, being a vertical section of a ball float
valve, Figure, 2, a vertical section of a modification and Figure, 3, a vertical section as
at right angles to Figure, 2. Figures, 4, 5, and, 6, are vertical sections of modifications
of my improved discharge valve for baths, and the like. In these drawings the same
reference numerals are used to mark the same or like parts wherever they are
repeated.
In carrying out my invention as shown in Figure, 1, I make the body, 7, of a supply
cock with an enlargement, S, at the inlet, and place in such enlargement one or more
perforated diaphragms, 9, as a device for diminishing noise: and instead of, or in
addition to this internal device I form an enlargement, 10, on the discharge nozzle
and place one or more perforated diaphragms 11, therein. I make the closing detail
or valve of a disk or button-like form on a plunger, 12, fitting a cavity in which it
works, such cavity being separate from the discharge orifice; and in a forked part of
the plunger, 12, as best seen in Figure, 3, I fit an antifriction roller, 13, to be acted
on by a cam, 14, formed on the float lever, 15. A horn, 16, is also formed on the
float lever, 15, to limit its downward movement. The parts are shown in the open
position in Figure, 1, and as closed in Figures, 2, and, 3. When the perforated
diaphragms (11) are not used a narrow discharge orifice, 17, Figure, 2, is made at
one side by preference at the inner side of the part in which the valve or plunger, 12,
works.
For a bath, basin, or other vessel I employ a discharge valve working at the
bottom of a vertical pipe or passage, 20, as shown in Figure, 4, at one end or side of
the vessel, 21, the valve, 22, being fixed or formed at the bottom of a tube, 23, which
in existing arrangements of the kind extends upwards in the pipe or passage, 20, to
serve as an overflow passage. In existing arrangements the vertical pipe or passage-
is always filled with water in the space round the valve tube (23) as high as the level
of the water in the bath or vessel, 21, and the water thus filling the pipe or passage is
wasted. By my invention I make the valve with an additional part, 24, which when
the mouth of the waste pipe, 25, is closed, also closes the bottom of the vertical pipe
or passage, 20, and prevents the water from getting up into it. The additional
part, 24, may be a rubber or other flange or collar closing down on a seat just above
the lateral inlet, 26, from the bath or vessel, 21, into the valve chamber as shown in
Figures, 4, and, 5; or it may be a rolling packing ring, 27, of rubber inserted
between a cylindrical part of the valve piece or tube, 23, and a cylindrical part
formed in the pipe or passage, 20, or in a piece fixed therein as shown in Figure, 6.
The rubber ring is by preference made out of a piece of straight rubber, or rubber
tube, one end (when the rubber is solid) having a pin formed on it to fit a socket
formed in the other end, and the joint being cemented if desired. A ring formed thus
rolls more freely than one moulded and cured in the form of a ring. The valve piece
is made with a passage, 23, through it and a tube may extend up from it as before for
the overflow, or it may be without a tube or have a short one. A separate overflow
outlet, 28, is provided at a suitable height in the end or side of the bath or vessel, 21,
and communicates with the tube or passage, 23, through the valve piece.
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 water supply valves the fitting of one or more perforated diaphragms in an
enlarged inlet space in the body of the valve or in an enlarged discharge space or in
both of such spaces, substantially as and for the purposes herein before described.
2-In a float-lever water-supply valve, forming the valve or closing detail on a
plunger working in a cavity separate from the discharge outlet and fitted with an

page_text: antifriction roller to be acted on by a cam on the float-lever, substantially as herein-
before described.
3-In connection with a discharge valve for a bath, basin, or other vessel, when
such valve is at the bottom of a vertical pipe or passage at the end or side of the
vessel providing an additional closing part to shut off the said pipe or passage from
the bottom of the vessel when the discharge valve is closed, substantially as herein-
before described.
4-Arranging the discharge-valve piece in a vertical pipe or passage at the end or
side of a bath, or basin, or other vessel, to work through a rolling packing ring,
substantially as hereinbefore described.
