IMPROVEMENTS IN APPARATUS FOR THE SUPPLY OF HOT WATER
Year: 1871

page_text: LETTERS PATENT to Richard Huskinson Warwick, of the Brewery, .
Newark-on-Trent, in the County of Nottingham, for the Invention
of "IMPROVEMENTS IN APPARATUS FOR THE SUPPLY OF HOT WATER."
‹PROVISIONAL SPECIFICATION left by the said Richard Huskinson
Warwick at the Office of the Commissioners of Patents, with his
Petition, on the 21st January 1871.
I, RICHARD HUSKINSON WARWICK, of the Brewery, Newark-on-Trent,
in the County of Nottingham, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN APPARATUS FOR THE SUPPLY OF HOT WATER,"
to be as follows:-
This Invention has for its object improvements in apparatus for the
supply of hot water.
.
In breweries and in many other places where steam is available a
supply of hot water is from time to time required, I employ for this
purpose a close tank or chamber, and I connect therewith two pipes,
one for the supply of cold water and the other for the supply of steam.

page_text: There is a stop valve on each of these pipes and the stop valves are
provided with floats which act upon them to close the passages when
the water rises to a certain level in the tank or chamber. The water
enters as a shower by perforations in the water pipe and falls upon
inclined shelves which direct it toward the steam pipe from perforations
in which the steam issues. In this way the water is caused to expose a
large surface to contact with the steam. The pipe by which the hot
water is drawn off is fitted at the bottom of the tank or chamber, and it
receives branches leading to the various places where the hot water may
be required, and each branch is provided with a valve or tap. An outlet
from the tank or chamber is provided for any air which may enter with
the water and steam, and also for the steam should it be in excess.
Plates are fixed in the tank or chamber to cause the steam to take a
circuitous course in passing from the inlet to the outlet, so that when the
quantity of steam admitted is duly proportioned to that of the water very
little may escape condensation. This adjustment is effected by means of
other cocks or valves on the steam and water pipes, and by means of
these the temperature of the water supplied by the apparatus may be
regulated:
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Richard Huskinson Warwick in the Great Seal
Patent Office on the 20th July 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
HUSKINSON WARWICK, of the Brewery, Newark-on-Trent, in the
County of Nottingham, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of January, in the year
of our Lord One thousand eight hundred and seventy-one, in the thirty-
fourth year of Her reign, did, for Herself, 'Her heirs and successors,
give and grant.unto me, the said Richard Huskinson Warwick, Her special
licence that I, the said Richard Huskinson Warwick, my executors, admi-
nistrators, and assigns, or such others as I, the said Richard Huskinson
Warwick, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make,

page_text: use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland; the Channel Islands, and Isle of Man, an Invention for
'IMPROVEMENTS IN APPARATUS FOR THE SUPPLY OF HOT WATER," upon the
condition (amongst others) that I, the said Richard Huskinson Warwick,
my executors or administrators, by an instrument in writing under my,
or their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same
was to be performed, and cause the same to be filed in the Great Scal
Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said Richard Huskinson Warwick,. do
hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement thereof, that is to say :-
This Invention has for its object improvements in apparatus for the
supply of hot water.
In breweries and in many other places where steam is available a
supply of hot water is from time to time required I employ for this
purpose a close tank or chamber, and I connect therewith two pipes, one
for the supply of cold water and the other for the supply of steam. There
is a stop valve on each of these pipes, and the stop valves are provided
with floats which act upon them to close the passages when the water rises
to a certain level in the tank or chamber, but both steam and water are
admitted when the water is drawn off and the level of the floats lowered.
The water enters as a shower by perforations in the water pipe and falls.
upon inclined shelves which direct it towards the steam pipe from per-
forations in which the steam issues. In this way the water is caused
to expose a large surface to contact with the steam. The pipe by which
the hot water is drawn off is fitted at the bottom of the tank or chamber,
and it receives branches leading to the various places where the hot
water may be required, and each branch is provided with a valve or tap.
An outlet from the tank or chamber is provided for any air which may
enter with the water and steam and also for the steam should it be in
excess. Plates are fixed in the tank or chamber to cause the steam to
take a circuitous course in passing from the inlet to the outlet so that
when the quantity of steam admitted is duly proportioned to that of the
water very little may escape condensation. This adjustment is effected
by means of other cocks or valves on the steam and water pipes, and:

Figure 3 is also a side view, but with the cover removed, and with some
of the parts in section; and Figure 4 is a vertical section.
a is a cistern or tank with a cover fitted air-tight; 6 is a water pipe
entering the cistern or tank; it is perforated on its upper surface; c is a
steam pipe similarly arranged, but the perforations in it are larger;
6¹ and c¹ are continuations of the pipes and c to the valves or cocks
d and e.
I use by preference screw valves opening and closing with a
quarter turn. The spindles of these valves are connected by the
couplings d¹ and e¹ with the axes ƒ and g which pass through stuffing
boxes into the cistern or tank. The couplings permit the endway play.

floats h and i within the cistern or tank.. The floats are carried by arms
f and g¹ with axes ƒ and g. k, k, are shelves on which the water
entering as a shower by the pipe 6 is as it falls directed towards and
amongst the steam issuing from the steam pipe c, so that it may
effectually condense the steam and itself become licated. is a pipe
with perforations in it for the escape from the cistern or tank of any air.
which may enter with the steam and water, and also of any small excess
of steam which may at times be admitted, especially when it is required
that the water drawn off should be at a boiling temperature. This outlet
pipe also prevents the water rising too high in the cistern or tank as it
might otherwise do from leakage of the valves when the apparatus stands.
long unused. The pipe is fitted with a valve opening outwards to
allow the escape of air, steam, or water, but preventing air passing into
the cistern or tank; m is a shelf to compel the steam to take a circuitous
course in passing from the steami pipe c to the escape. pipe ; n is a
perforated pipe by which where it is convenient the exhaust steam from
a steam engine may be admitted to the cistern or tank; o is the pipe by.
which the hot water is drawn off; it leads by as many branches as may.
be required to the places where the supply is wanted for usc.
A.s

page_text: the hot water is drawn off the floats fall and open the valves to admit
both steam and water to the cistern or tank, and this goes on until by
the accumulation of the water the floats are again raised and the valves
closed.
Having thus described the nature of my said Invention, and the
manner of performing the same, I would have it understood that I
claim the construction of apparatus for the supply of hot water, sub-
stantially as described.

In witness whereof, I, the said Richard Huskinson Warwick, have
hereunto set my hand and seal, this Nineteenth day of July, in
the year of our Lord One thousand eight hundred and seventy-
one.
