[mprovements in Valve Apparatus for Controlling Water Supply in
Public and other Baths.
I, JAMES KEITH, Assoc. M. Inst. C.E. of 57 Holborn Viaduct in the City of
London, Gas, Hydraulic, Heating and Ventilating Engineer, do hereby declare
the nature of this invention to be as follows:-
This invention has for its object the provision of improved valve apparatus for
controlling the supply of water to public and domestic baths and its discharge
therefrom.
Under the invention the admission valves on the series of service pipes for sup-.
plying water to the baths such as hot, cold or sea-water are operated by means of
cams or eccentrics upon a spindle having a lever handle or handing wheel connected
to it either directly or through gearing and carrying a pointer over a disc or dial,
the cams or eccentrics being so set one in advance of the other that by turning the
spindle to a greater or less extent one or other of the valves of the service pipes is
opened or they are all opened more or less to admit hot, cold, or sea-water or such
an admixture as may be desired, the disc or dial over which passes the pointer on
the lever handle being suitable graduated to indicate the extent of opening of the
several valves.
The valves are or may be of the disc or conical type and may be maintained on
their seats in a valve casing by the water pressure whilst the ends of their guide
spindles bear upon the peripheries of the eccentrics which operate them.
The waste or discharge valve rests on a seat formed in a chamber connected by
branch pipe to the bottom of bath with a vertical part standing up outside end of
bath the whole being placed on or over a trap or bend which is connected by a
loose flange to the waste valve arrangement mentioned by bolts or other means
permitting of swivelling the trap or bend to any angle desired. The discharge
valve is connected by a rod or link to a float which may be placed in the aforesaid
stand pipe and is operated by a pull or other handle to discharge the contents of
the bath, whilst the float by lifting the valve when the water level exceeds the
normal takes the place of an overflow the arrangement also ensuring effectual
shutting off of the discharge outlet from the drain in addition to the trapping
mentioned between the dead-tight waste valve and the said drain.

Improvements in Valve Apparatus for Controlling Water Supply in
Public and other Baths.
I, JAMES KEITH, Assoc. M. Inst. C.E. of 57 Holborn Viaduct in the City of
London, Gas, Hydraulic, Heating and Ventilating Engineer, do bereby 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 has for its object the provision of improved valve apparatus for
controlling the supply of water to public and domestic baths and its discharge
therefrom

page_text: As represented by the accompanying sheet of drawings which shews my inven-
tion applied to a bath,
Fig. 1 is a vertical section of the bath shewing the float arrangement and Fig. 2
a plan, whilst Figs. 3 and 4 are respectively a vertical section of the admission
valve apparatus and a plan of the dial and pointer.
Under the invention the admission valves A. B, of which there may be two or
more, on the series of service pipes C. D. for supplying water to the baths E such
as hot, cold, sea, or other water are operated by means of cams or eccentrics F. F¹
upon a spindle G having a lever handle H or handing wheel connected to it either
directly or through gearing and carrying a pointer I over a disc or dial J, the cams
or eccentrics being so set one in advance of the other that by turning the spindle
to a greater or less extent one or other of the valves A or B of the service pipes
opened or they are all opened more or less to admit hot, cold or sea-water or such
an admixture as may be desired, the disc or dial J over which passes the pointer I
on the lever handle being suitably graduated to indicate the extent of opening of
the several valves. The spindle G may be actuated if desired by means of a rack
and pinion or quadrant arrangement, the whole valve apparatus being placed to
suit the kind of gearing used.
The valves A. B. which are of the disc, but may be of the conical or other type
are maintained on their seats K in a valve casing L by the water pressure; or
spiral springs may be placed around the guide spindles between the upper side of
the valves A. B. and the bridges of the air vessel caps where the pressure of water
is weak, whilst the ends of their guide spindles bear upon the peripheries of the
eccentrics which operate them against the water pressure. These valves are made
absolutely silent worki ng by means of the air vessels M, N, fitted over them, and
may be operated from either end of the spindle G if desired.
The waste or discharge valve O rests on a seat P formed in a chamber Q con-
nected by a branch pipe R to the bottom of bath C with a vertical part standing
up outside end of bath the whole being placed on or over a trap or bend S which
is connected by a loose flange S₁ to the waste valve O by bolts or other means
permitting of swivelling the trap or bend S to any angle desired. The discharge
valve O is connected by a rod or link T to a float U which is placed in the afore-
said stand pipe and is operated by a pull or other handle V to discharge the
contents of the bath, whilst the float by lifting the valve O when the water level
exceeds the normal takes the place of an overflow the arrangement also ensuring
effectual shutting off of the discharge outlet from the drain in addition to the
trapping mentioned between the dead-tight waste valve and the said drain.
Having now particularly described and ascertained the nature of my said inveu-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination of parts constituting the improved valve apparatus for con-
trolling water supply in public and other baths substantially as described.
2. In valve apparatus for controlling water supply in public and other baths the
arrangement of cams or eccentrics operating the admission valves against the water
pressure substantially as set forth.
3. In valve apparatus for controlling water supply in public and other baths an
automatic overflow and waste arrangement consisting of a float actuating a valve to
discharge part of the contents of the bath substantially as set forth.
Dated this Ninth day of August 1893.
