IMPROVE- MENTS IN HEATING THE WATER IN A BATH OR OTHER VESSEL
Year: 1853

page_text: LETTERS PATENT to Frederick Arnold, of Devonport, in the
County of Devon, Ironmonger, for the Invention of "IMPROVE-
MENTS IN HEATING THE WATER IN A BATH OR OTHER VESSEL."
Sealed the 9th April 1858, and dated the 5th January 1858.
PROVISIONAL SPECIFICATION left by the said Frederick Arnold at
the Office of the Commissioners of Patents, with his Petition, on
the 5th January 1853.
I, FREDERICK ARNOLD, of Devonport, in the County of Devon, Tron-
monger, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN HEATING THE WATER IN A BATH OR OTHER VESSEL " to
be as follows:
This Invention consists of constructing and using one or more gas-
heating chambers, open below, and having openings above covered
with wire guaze. These are placed under a boiler, which is, by pre-
ference, of a rectangular form, having tubes rising into it, which are
open below and closed above. Into these tubes the heat passes, and
heats the water surrounding them. The boiler is enclosed in a case,
and is in connection with a bath or other vessel by means of several

page_text: tubes, by which the water flows from the boiler to the bath or other
vessel, and from the bath or other vessel to the boiler. Gas is used
for heating the apparatus, and flows from the gas main in the
chambers, into which air enters freely below, and the gas and air are
inflamed at the openings at the top of these chambers.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Frederick Arnold in the Great Seal Patent Office,
on the 5th July 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
FREDERICK ARNOLD, of Devonport, in the County of Devon, Iron-
monger, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifth day of January, in the of
our Lord One thousand eight hundred and fifty-three, in the six-
teenth year of Her reign, did, for Herself, Her heirs and succes-
sors, give and grant unto me, the said Frederick Arnold, Her special
licence that T, the said Frederick Arnold, my executors, administra-
tors, and assigns, or such others as I, the said Frederick Arnold, my ex-
ecutors, 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 HEATING THE WATER IN A BATH OR OTHER VESSEL," upon the
condition (amongst others) that I, the said Frederick Arnold, 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 same was to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Frederick Arnold, do hereby
declare the nature of the said Invention, and in what manner the

page_text: same is to be performed, to be particularly described and ascertained
in and by the following statement thereof (that is to say):
This Invention consists of constructing and using one or more gas-
heating chambers, open below, and having openings above covered
with wire gauze. These are placed under a boiler, which is, by pre-
ference, of a rectangular form, having tubes rising into it, which are
open below and closed above. Into these tubes the heat passes, and
heats the water surrounding them. The boiler is enclosed in a case,
and is in connection with a bath or other vessel by means of several
tubes, by which the water flows from the boiler to the bath or other
vessel, and from the bath or other vessel to the boiler. Gas is used for
heating the apparatus, and flows from the gas main into the chambers,
into which air enters freely below, and the gas and air are inflamed at
the openings at the top of these chambers. And in order that my
Invention may be more fully understood, and readily carried into effect,
I will proceed to describe the means pursued by me.
DESCRIPTION OF THE DRAWING.
Figure 1, shows a longitudinal section; Figure 2, a side view; and
Figure 3, a transverse section of apparatus constructed according to
my Invention applied to a bath. Figure 4, shews separate views of
one of the gas-heating chambers. a, a, are the gas-heating chambers,
which are open at the bottom, and have openings at the upper part
covered with fine wire gauze; the gas-heating chambers a, are placed
below the boiler b, which has a number of tubes b', ', rising into it,
open below and closed above, into which the heat from the gas-heating
apparatus passes, and heats the water surrounding them. 2, is a case
which surrounds the boiler; and c, c, are tubes or passages through
which the water circulates from the boiler to the bath or other vessel,
and from the bath or other vessel to the boiler, to which circulation,
however, I make no claim. Gas is supplied to the chambers a, a,
through the stop-cocks, as shewn, and it will combine with the air in
the chambers, and pass up through the openings covered with wire
gauze, and may be ignited by opening the door , and the products of
combustion will pass away by the pipe d.

page_text: Having thus described the nature of my Invention, and the manner
of performing the same, I would have it understood that I do not
confine myself to the precise details herein shewn and described. But
wliat I claim is, the mode of heating water in a bath or other vessel by
gas apparatus a, a, as herein described.
In witness whereof, I, the said Frederick Arnold, have hereunto
set my hand and seal, this Fourth day of July, in the year of our
Lord One thousand eight hundred and fifty-three.
Witness,
J. G. TONGUE.
FREDERICK ARNOLD. (L.S.).
