IMPROVEMENTS IN APPARATUS FOR HEATING WATER AND OTHER FLUIDS
Year: 1853

page_text: Scaled the 2nd May 1854, and dated the 19th November 1858.
PROVISIONAL SPECIFICATION left by the said James Harris at.
the Office of the Commissioners of Patents, with his Petition, on
the 19th November 1853.
I, JAMES HARRIS, of Hanwell, in the County of Middlesex, En-
gineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR HEATING WATER AND OTHER FLUIDS"
to be as follows:-
My improvements relate to apparatus for heating water and other
fluids for brewhouses, distilleries, dyers, baths and wash-houses, asylums,
conservatories, drying rooms, &c. by means of steam brought direct
from the boiler, or by means of superheated steam, or of the discharged
steam from high pressure or other engines, the latter arrangement

page_text: being especially applicable for heating the water in its passage from
the feed pump to the boiler in steam engines. My improved
apparatus consists of a vertical cylinder or vessel fitted with a series
of tubes, similar to the boilers of locomotive engines, with a second
or false cover at each end, forming chambers for the admission and
exit of the water. The false covers are made moveable, for con-
venience in cleansing the tubes and effecting repairs when needful.
The steam is admitted into the cylinder and around the tubes; the
same apparatus may therefore, without the false covers, be employed
for the purpose of heating air, for warming and ventilating.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Harris in the Great Seal Patent Office
on the 19th May 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JAMES HARRIS,. of Hanwell, in the County of Middlesex, Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of November, in the
year of our Lord One thousand eight hundred and fifty-three, in the
seventeenth year of Her reign, did, for Herself, Her heirs and succes-
sors, give and grant unto me, the said James Harris, Her special
licence that I, the said James Harris, my executors, administrators,
and assigns, or such others as I, the said James Harris, 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, 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 HEATING WATER AND OTHER FLUIDS," upon the condition
(amongst others) that I, the said James Harris, by an instrument in
writing under my hand and seal, should particularly describe and
ascertain the nature of the said Invention, and in what manner the

page_text: same was to be performed, and cause the same to be filed in the
Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said James Harris, do hereby declare
the nature of my 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, reference being had to the Drawings here-
unto annexed (that is to say):-
My Invention relates to apparatus for heating water and other fluids
for brewhouses, distilleries, dyers, baths and wash-houses, asylums, con-
servatories, drying rooms, &c. by means of steam brought direct from
the boiler, or by means of superheated steam, or of the discharged
steam from high pressure or other engines. My improved apparatus
consists of a vertical cylinder or vessel fitted with a series of tubes, in a
similar manner to the boiler of a locomotive engine, with a second or
false cover at each end, forming chambers for the admission and exit of
The false covers are made
the water or other fluid to be heated.
moveable, for convenience in cleaning the tubes and effecting repairs
when needful. The steam is admitted into the cylinder and around the
tubes, and the water or other fluid is heated by passing through them.
The same apparatus, without the false covers, may be employed for the
purpose of heating air for warming and ventilating buildings of any
description, by means of either hot water or steam admitted into the
cylinder.
Figure 1, of the Drawings annexed is an elevation; and Figure 2,
a plan of my improved apparatus; Figure 3, is a vertical section of the
same on the line a, b, of Figure 4, which is a horizontal section on the
line c, d, of Figure 3. Figure 5, is an elevation of a syphon, which is
attached to the bottom of the apparatus for the purpose of drawing off
the water produced by the condensation of steam in the cylinder. A, A,
is the vertical cylinder or vessel, and B, B, its end covers, which are
secured to the cylinder by rivets a, a, through the angle iron rings b; b,
or in any other convenient manner; C, is a wrought iron stay rod at
the centre of the cylinder, the ends of which are secured in the end
covers B, B, by nuts c, c; D, D, are the tubes, which are fitted to the

page_text: cylinder A, A, by any convenient means; E, E, are the false covers to
the ends of the cylinder which are secured thereto by the bolts and nuts
d, d, to admit of their being removed when necessary; F, is the inlet
for the water, and G, the outlet for the same; H, is the steam inlet,
and I, a pipe for the exit of the air; J, is a pipe from the cylinder
through the bottom of the apparatus, to which the syphon K, Figure 5,
is attached by a union-joint for the purpose of allowing the condensed
water to escape from the cylinder. When the apparatus is in use the
steam inlet is to be connected to the steam pipe from the boiler or other
source, and the water inlet and outlet to the supply and delivery pipes
respectively. The steam is admitted to the interior of the cylinder, and
water or other fluid is allowed to pass through the tubes, when it will
be heated by the steam which circulates around the tubes.
And having now described the nature of my said Invention, and
in what manner the same is to be performed, I declare that what I
claim as my Invention is,―
The tubular apparatus for heating water and other fluids by steam,
as represented in the Drawings annexed and herein-before described.
In witness whereof, I, the said James Harris, have hereunto set
my hand and seal, this Thirteenth day of May, One thousand
eight hundred and fifty-four.
