PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Heating Water.
I, THOMAS CASSIENET PALMER, of the Firm of W. J. Fraser & Co., of 98,
Commercial Road East, in the County of London, Engineer, do hereby declare
the nature of this invention to be as follows:
This invention relates to a simple and efficient apparatus for heating water by
bringing it into direct contact with steam which it condenses whilst absorbing
its heat.
According to my invention I provide a mixing chamber into which cold water
is conveyed through an annular inlet in communication with a feed pipe and
into which mixing chamber steam is conveyed through an opening in the centre
of the annular water inlet.
To control the inlet of water and steam I provide a valve comprising a disc loose
on a spindle and designed to be screwed against the flat valve face in which the water
and steam inlets are made, a central conical plug being attached to the valve
spindle and adapted to enter the correspondingly coned steam inlet opening. The disc
is advantageously operated, through the medium of a hand wheel by a spindle
having a quick thread so that a turn of the hand wheel will fully open the cold
water inlet, the further movement of the said hand wheel only affecting the steam
inlet. The condensed steam and water in the mixing chamber escape through
a perforated partition surrounding the said chamber into an outlet passage for
the hot water.

Improvements in Apparatus Ior Heating water.
I, THOMAS CASSIENET PALMER, of the Firm of W. J Fraser & Co., of 98,
Commercial Road East, in the County of London, 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:-
-
This invention relates to a simple and efficient apparatus for heating water by
bringing it into direct contact with steam which it condenses whilst absorbing
its heat.
According to my invention I provide a mixing chamber into which cold water
is conveyed through an annular inlet in communication with a feed pipe and

page_text: into which mixing chamber steam is conveyed through an opening in the centre
of the annular water inlet.
To control the inlet of water and steam I provide a valve comprising a disc
on a spindle and designed to be screwed against the flat valve face in which the water
and steam inlets are made, a central plug being attached to the valve
spindle and adapted to enter the coned steam inlet opening. The disc is
advantageously operated through the medium of a hand wheel or handle
fitted to the screwed spindle, a turn of which handle or wheel will fully open
the cold water inlet and not the steam, the further movement of the said hand
wheel only affecting the steam inlet. The condensed steam and water in the
mixing chamber escape through a perforated partition surrounding the said
chamber into an outlet passage for the hot water.
To enable my invention to be fully understood I will describe it by reference to
the accompanying drawing, in which:-
Figure 1 is a vertical section of apparatus for heating water made according to
my invention; and,
Figure 2 is a section on the line 2-2 Figure 1.
a is the mixing chamber, b is the inlet for the cold water, the said inlet being
as shewn annular in form, and c is the inlet for the steam, the said inlet being
arranged in the centre of the annular water inlet.
...d is the disc forming the valve for controlling the inlet for the water, the said
valve being provided with a renewable face e preferably of asbestos and f is the
spindle upon which the said valve is mounted, the said spindle being screw-threaded
and arranged to work in the screw-threaded hole y in the end of the mixing
chamber a. The outer plain part of the spindle f passes through a stuffing box h
and is provided with the handle i by means of which the spindle can be rotated
so as to raise or lower the valve d away from or upon its seat. The steam inlet c
is shewn conical, that is to say, it tapers from above downwards and it is closed
by the plug secured to the valve d in such a manner that its distance therefrom
can be regulated in order that the amount of lift given to the said valve d before
the plug opens the steam inlet can be regulated.
k is the perforated partition surrounding the mixing chamber a and is the
outlet passage for the water which has been heated by condensing the steam in
the mixing chamber.
It will be obvious that by suitably adjusting the extent to which the steam
inlet is opened the heat of the water delivered by the valve can be regulated
as desired.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is:
1.
The combination and arrangement of parts forming the improved mixing valve
for steam and water hereinbefore described and illustrated in the accompanying
drawing.
