PROVISIONAL SPECIFICATION.
An Apparatus or Valve for Regulating the Temperature of Water
passed through it.
We, HARRY WARD and FREDERICK WILLIAM Nock, both Hot Water Engineers,
of 100, Snow Hill, Birmingham, do hereby declare the nature of this invention
to be as follows:-
-
We have two pipe connections to our valve, one for the admission of steam &
one for water.
The water on being admitted to the valve may pass out by either one of two
ways, or it may pass out partly through one way and partly through the other way.
As soon as the water admission valve is raised from its seat, (by means of the
ordinary screw arrangement) to admit the water, the water passes round the valve,
which has a face, both on its upper and lower sides, and up round the valve spindle
and directly to the outlet of the cock. Thus we get a supply of cold water.
When, however, we raise the valve further, the upper face of the valve is brought
against its seating, thus preventing any more water from passing out that way.
The water now passes into a chamber in which is fitted à piston or other con-
trivance on the upper face of which the water presses, thus depressing the piston
and allowing the water to escape past the piston and into another chamber where
it is mixed with the steam as described below.
By regulating the water admission valve by keeping it nearer to or further away
from its upper seating, the amount of water which passes direct to the outlet, and
the amount which passes over and past the piston is varied at will, and we thus
combine more or less of the water with steam, and obtain any desired tempera-
ture between cold and boiling water.
When the pressure of the water depresses the piston it also overcomes the pres-
sure of the steam on a small valve connected to the piston, and opens the valve.
Steam then passes the valve and enters the chamber below the piston into which
the water has obtained access as described above, and combines with the water
therein.
Our arrangement is such that until the pressure of water comes on to the piston
the action of the steam keeps its valve closed, and thus prevents any steam getting
through the tap without water.
A small non return valve is fitted, either as forming part of our valve itself,
or it
may be placed on the steam pipe, to prevent any water passing back into the
steam pipe.
It will be evident from the above description that the water having become com-
bined with the steam may pass on through any required length of pipe or may
at once find an outlet if we so desire.
We sometimes place a number of valves or cocks of ordinary pattern, on the
delivery pipe. In this case the double faced water valve may be left open, and no
water or steam can get through until one or more of the valves or cocks on the
delivery pipe are opened.

page_text: Immediately one of such valves or cocks is opened our double faced valve allows
the water to pass, and to combine with the steam as previously described.
Thus by fixing one valve of our invention as described herein, and connecting
it up to steam and water we may obtain hot water (or cold) at any number of
points in a building. For instance one of our valves will supply a whole range of
baths or wash houses with hot water.

An Apparatus or Valve for Regulating the Temperature of Water
passed through it.
We, HARRY WARD and FREDERICK WILLIAM Nocк, Hot Water Engineers, of
100, Snow Hill, Birmingham, in the County of Warwick, 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:-
Our invention consists of a water heater or apparatus wherein water is heated
by means of introduced steam.
In the construction of our water heater we provide two pipe connections, one for
the admission of steam and one for the admission of water.
The water on being admitted to the heater may pass out by either one of two
ways, or it may pass out partly through one way and partly through the other
way.
As soon as the water admission valve is raised from its seat by means of the
ordinary screw arrangement to admit the water, the water passes round the valve
(which has a face both on its upper and lower sides), and up round the valve
spindle and directly to the outlet of the cock, thus we get a supply of cold water;
when however we raise the valve further, the upper face of the valve is brought
against its seating thus preventing any more water from passing directly upwards;
the water then passes into a chamber in which is fitted a piston or other contriv-
ance on the upper face of which the water presses, thus depressing the piston, and
allowing the water to escape past the piston and into a lower chamber where it is
mixed with the steam as described below.
We regulate the water admission valve by keeping it nearer to or further away
from its upper seating, the amount of water which passes direct to the outlet,
and the amount which passes over and past the piston is varied at will, and we
thus combine more or less of the water with the steam, and obtain any desired
temperature between cold and boiling water.
When the pressure of the water depresses the piston it also overcomes the pres-
sure of the steam on a small valve connected to the piston, and opens the valve;
steam then passes the valve and enters the chamber below the piston into which
the water has obtained access as described above, and combines with the water
therein.
Our arrangement is such that until the pressure of water comes on to the piston
the action of the steam keeps its valve closed, and thus prevents any steam getting
through the tap without water: a small non-return valve is fitted either as forming
part of our heater itself or it may be placed on the steam pipe, to prevent any
water passing back into the steam pipe.
It will be evident from the foregoing description that the water having become

page_text: combined with the steam may pass on through any required length of pipe or may
at once find an outlet if we so desire.
We sometimes place a number of valves or cocks of ordinary pattern on the
delivery pipe in such cases the double faced water valve may be left open and
neither water nor steam could then get through until one or more of the valves
or cocks on the delivery pipe were opened; immediately one of such valves or
cocks is opened our double-faced valve or its equivalent allows the water to pass,
and to combine with the steam as previously described, thus by fixing one valve
of our invention as described herein, and connecting it up to steam and water we
may obtain, hot or cold water at any number of points in a building, for instance
one of our heaters would supply a whole range of baths or wash houses with hot
water.
We will now proceed to describe with reference to the accompanying drawings
the manner in which our invention is constructed and used.
Figure 1 represents a vertical section of our improved apparatus or valve con-
structed with one outlet.
Figure 2 represents a vertical section of our improved apparatus or heater in
a modified form suitable to supply hot water to any number of outlets.
In carrying out our invention in relation to the apparatus with one outlet as
represented at Figure 1 we provide the casting as represented in section and
marked a, we provide a water inlet 6 connected to the casting a by means of the
union c, and below the water inlet we connect to the casting a a steam inlet d by
means of the union e; f is the outlet for the heater, g is the piston beyond which
the water must flow, h is a valve through which the steam passes, j is a check valve
provided to prevent water entering the steam pipe d, k is an annular opening pro-
vided to pass the water ready to mix with steam, is a spindle provided to connect
the water piston 9 with the steam valve h so that when the water piston y is
depressed the steam valve his opened, m is the chamber within which the water
and steam is mixed, n are holes through which the mixed water and steam pass,
the heated water eventually discharging at f.
In using our apparatus or heater as illustrated in relation to Figure 1 water is
admitted through the pipe b and passes upwards through the outlet o when the
valve is in the raised position as shewn, the water may then travel direct to the
outlet f, or if the valve p is raised until the outlet q is closed the water enters
the chamber and flows past the side of the piston g and thence upwards through
the annular opening k into the chamber m where it mixes with the steam and
passes through the holes n and out through the delivery end f.
The pressure of the introduced water on the piston 9 from the chamber ris
exerted in a downward direction, consequently as the piston is connected to the
steam valve h by means of the rod such downward travel moves the valve h, open-
ing the same and permitting steam to rush in from the steam connection d, to mix
with the water in the chamber m.
When the cold water pressure is relieved from the top of piston g the spiral
spring s pressing against the under side of such piston g lifts the steam valve h
into its bearing position over the steam-inlet passage; the pressure of steam on
the under side of the steam valve constitutes the main sealing pressure of the
valve h, the spring s exerting a secondary or supplementary sealing pressure.
In carrying out our invention in relation to the heater or apparatus as repre-
sented at Figure 2 suitable for supplying hot water to any desired number of
outlets we provide the casting a and other parts marked with the indicating
letters, each of such letters shews a part similar or equivalent to the part marked
with the same letter on the illustration Figure 1.
Some of the parts used in the structure shewn at Figure 1 are not necessary in
the structure shewn at Figure 2, the weight of the piston g Figure 2 closing the
steam valve without the use of the spring s; the regulating valve and its screw
connections are also dispensed with in the structure shewn at Figure 2, never-
theless the action of the cold water through the inlet passage b in conjunction

page_text: with the action of the steam introduced through the inlet
is precisely the same
in relation to both the modifications shewn at Figures 1 and 2.
Check valves t and u are provided in connection with the structure shewn at
Figure 2 to prevent the return action of the steam and water.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed we declare that what
we claim is:-
1st. An apparatus valve or heater for regulating the temperature of water passed
through it and for delivering either hot or cold water, the apparatus or heater con-
sisting of a casing or shell provided with an inlet water passage and an inlet steam
passage, the inlet water passage being regulated by means of an adjusting-valve
taking over an outlet passage leading into a mixing chamber and the inlet steam
passage being regulated by means of a steam valve connected to close or open the
mixing chamber, so that water and steam can be conducted into the mixing cham-
ber to mix therein and pass outwards through suitable passages into a delivery-
orifice and thus deliver water heated to any desired temperature, or so that cold
water only can be passed through the casing or shell into the delivery orifice
and thus deliver cold water through such delivery orifice as illustrated and described
herein in relation to Figures 1 and 2.
