Improvements in Liquid-controlling Appliances for Supplying Baths,
Lavatories, and the like.
I, DAVID MCCULLOCH of 44 Dundonald Road, Kilmarnock, Ayrshire,
Engineer, do hereby declare the nature of my invention to be as follows:—
This invention has reference to an improved construction or arrangement and
combination of appliances for regulating or controlling the supply of coll and hot
water to baths, lavatories and the like.
According to my improvements I fit separate cold and hot water chests, or
casings in the same axial line, (although these may be formed in one casting with
division wall between them), and each would be formed with inlet and outlet
branches at opposite sides to which would be coupled the respective pipes from
cisterns or mains and to baths. In the cold water chest a central spindle is fitted,
passing through a cover and stuffing box at one end of chest, and having its
opposite end fitting loosely within the central hollow part of a hand spindle
working within a cover fitted at opposite end of chest, this hand screw spindle
passes in through a stuffing box at outer end of cover and has the threads of
screw working into the internal screwed boss of cover. A central hollow duplex
faced disc or ring flange seat is formed inside the chest between the inlet and
outlet branches, find valves are fitted on the spindle on each side of this. The
valve on the one side of seat would consist of a disc formed or screwed on to
spindle with leather or other washer in front bearing on sent, and a helical gun-
metal or phosphor bronze spring would be interposed between a shoulder behind
disc and a shoulder on the end cover of chest, so as to keep the valve closed when
a supply of cold water is not desired. The valve on opposite side of seat would
consist of a similar disc and washer secured on spindle some distance from seat in
the closed position of the other valve and held in position by jamb nuts.
The hot water chest would be fitted with a separate spindle in axial or straight
line with that of the cold water chest and the one end of this spindle would work
loosely within a central socket formed on a closed end cover of chest, while the
other end of spindle would pass through a stuffing box in the opposite end cover
of chest.
A disc valve is fitted on the spindle at the inlet side of ring seat between inlet
and outlet branches and a helical valve closing spring is interposed between this
valve and an annular recess in end cover of chest in an analogous manner, to that
of the cold water chest, but requiring no valve on the opposite face of ring seat.
The adjacent ends of the valve spindles of chests work freely within a coupling
socket or housing, and in the normal closed position of the valves the ends are n
short distance from each other.
:-
The operation of these appliances is as follows -The attendant first places a
portable disc ring or wheel on the hand spindle and turns same a predetermined
distance when the inner end of hand spindle will press on valve spindle to open
the inlet valve of cold water chest and the cold water will then flow through same
to the bath. By turning the handle a further distance the end of cold water
valve spindle will press on end of spindle of hot water chest and pen this valve a
certain distance, so that both cold and hot water will simultaneously flow thr ugh
the valve chests into bath. By turning the valve spindle still further the valve ou

page_text: outlet side of ring sent will be pressed up against seat and so shut off the supply
of cold water, and then only hot water will flow into bath; so that by adjusting the
hand spindle the flow of cold and hot water can be regulated simultaneously by
the one operation to suit the temperature desired. A fixed pointer may be fitted
on end cover of cold water chest, and graduated marks be formed on hand spindle,
so that the position these latter bear with the pointer will at once show the distance
to which the hand spindle should be turned, such as for cold, tepid or hot water or
to correspond to any predetermined temperatures which may be indicated by n
thermometer fitted on the delivery pipe.
The outlet branches from the cold and hot water chests may lead into a
"breeches" pipe or connecting delivery branch leading into bath.

Improvements in Liquid-controlling Appliances for Supplying Baths,
Lavatories, and the like.
1, DAVID MCCULLOCH, of 44 Dundonald Rad, Kilmarnock, Ayrshire,
Engineer, do hereby declare the nature of my invention, and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement in writing, that is to say :-
This invention has reference to an improved construction or arrangement and
combination of appliances for regulating or controlling the supply of cold and hot
water to baths, lavatories, and the like.
And in order that my said invention and the manner of performing or carrying
same into practice may be properly understood, 1 have hereunto appende two
sheets of explanatory drawings, in which
Figure represents a sectional elevation of one arrangement of my liquid
controlling appliances in which the cold and hot water chests are shown as formed
in separate casings; while
Figure 2 represents a similar view in which these chests are shown as formed in
one casting. And
Figures 3 and 4 are respectively a plan view and end elevation corresponding to
Figure 2.
Referring to Figure 1 of these drawings:-
:--
According to my improvements I fit separate cold and hot water chests or
casings, A and B in the same axial line, and each would be formed with inlet and
outlet branches C and Cat opposite sides to which would be coupled the
respective pipes from cisterns or mains and to baths. In the cold water chest A a
central spindle D is fitted passing through a ever and stuffing box A' at one
end of chest A and having its opposite end fitting loosely within the central
hollow part D of a hand spindle D' working within a cover fitted at opposite
end of chest A. This hand screw spindle D' passes in through a stuffing
box Aat outer end of cover A and has the threads of screw working into the
internal screwed toss of cover at A'. A central hollow duplex faced dise or ring
flange seat a is formed inside the chest. A between the inlet and outlet branches C C
and valves a' a² are fitted on the spindle D on each side of this. The valve a¹ on
the one side of seat a would consist of a disc formed or screwed on to spindle B with
leather or other washer in front bearing on seat a and a helical gun metal or
phosphor broi ze spring a would be interposed between a shoulder behind disc a
and a shoulder on the end cover A' of chest, so as to keep the valve a' closed
when a supply of cold water is not desired. The valve a' on opposite side of seat a

page_text: would consist of a similar disc and washer screwed or secured on spindle some
distance from seat a in the closed position of the other valve and held in position
by jamb nuts.
The hot water chest 13 would be fitted with a separate spindle D' in axial or
straight line with that D of the cold water chest A and the one end of this
spindle D would work loosely within a central socket B* formed on a close end
cover B of chest B while the other end of spindle D' would pass through a stuffing
box in the opposite end cover 13³ of chest.
A disc valve is fitted on the spindle D2 at the inlet side of ring seat between
inlet and outlet branches C C and a helical valve closing spring is interposed
between this valve and an annular recess B in end cover B' of chest B in an
analogous manner to that of the cold water chest A, but requiring no valve on the
opposite face of ring sent. The adjacent ends of the valve spindles B B2 of
chests A B work freely within a coupling socket or housing B and in the
normal closed position of the valves the ends are a short distance from
each other.
The operation of these appliances is as follows:-The attendant first places a
portable disc ring or wheel D³ on the hand spindle D' and turns same a prede-
termined distance when the inner end of hand spindle will press on valve spindle D
to open the inlet valve a' of cold water chest A. and the cold water will then flow
through same to the bath. By turning the handle 1³ a further distance the end
of cold water valve spindle D will press on end of spindle D' of hot water chest B
and open the valve a certain distance, so that both cold and hot water will
simultaneously flow through the valve chests into ballı.
By turning the valve spindle D' still further the valve a² on outlet side of ring
sent a will be pressed up against sent and so shut off the supply of cold water and
then only hot water will flow into bath, so that by adjusting the hand spindle DI
the flow of cold and hot water can be regulated simultaneously by the one operation
to suit the temperature desired. A fixed pointer d may be fitted on the spindle D'
and graduated marks be formed on a fixed plate d' so that the position these latter
bear with the pointer will at once show the distance to which the hand spindle
should be turned for the closed or open positions of the respective valves.
The outlets from the cold and hot water chests may lend by branches C2 into a
"breeches" pipe or connecting delivery branch C leading into bath.
In the arrangement shown in Figures 2 to 4, the cold and hot water chests A B
are formed in the same casting or casing, and the spindles D D' connected together
by a nute or other fastening. In this arrangement when the pointer d is at the
mark the valves a' are both closed on their seats ab but when the spindle D'
is turned and the pointer is moved inwards to the valve a' is moved off its seat a
and is full open for the passage of cold water to outlet branch C', the valve bof
the hot water chest being meantime closed. When the spinelle D' is still further
turned and the pointer d moves inwards to the valve a still remains full open
and the end of valve a¹ will have moved forward and acted on the end of the
spindle D resting in its socket projection a³ and pushed this spindle D inwards
to open the valve & full open, so that now both cold and hot water are flowing to
the outlet branch Cl.
When the spindle D₁ has been further turned and the pointer moved inwards
to the valve of the hot water supply will still remain full open, but the valve a²
will now have moved forward against the sent a and shut off further supply of
cold water to the outlet branch C. The valve al may be held against the seat a
in its closed position by the action of the spindles D D' alone, but the spring a³
may be used if desired.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
First. The construction and arrangement in combination of the paris of liquid

page_text: controlling appliances for supplying baths Invatories and the like, substantially as
herein described in reference to and shown in the accompanying drawings.
Second. In liquid controlling appliances for supplying baths, lavatories and
the like, the arrangement in combination of three valves with spindles all in
line and operated from one handle to control the supply of cold and hot water
substantially as herein described in reference to and shown in the accompanying
drawings.
