Year: 1854

page_text: LETTERS PATENT to Edward Batten Walmsley, of Middle Mall, Hammer-
smith, in the County of Middlesex, Iron Merchant, for the Invention of
"IMPROVEMENTS IN UTENSILS, IMPLEMENTS, AND APPARATUS FOR THE PURPOSES
OF LIGHTING. HEATING. AND COOKING."
PROVISIONAL SPECIFICATION left by the said Edward Batten Walmsley
at the Office of the Commissioners of Patents, with his Petition, on
the 25th January 1854.
I, EDWARD BATTEN WALMSLEY, of Middle Mall, Hammersmith, do hereby
; declare the nature of the said Invention for "IMPROVEMENTS IN UTENSILS.
IMPLEMENTS, AND APPARATUS FOR THE PURPOSES OF LIGHTING, HEATING, AND
COOKING," to be as follows:-
I introduce the air external to a building through a pipe or tube or other
confined or enclosed passage to a space in which I intend combustion to take
place or be achieved, which I secure from the admission or intrusion of air
from within the building by means of an appropriate enclosure. For the
escape or egress of the smoke, vapour, or gas, I attach one end of a pipe or
tube to the furnace chimney or flue, and pass the other to the exterior of the
building. I obtain access to the said enclosed space by a division or seperation
of the enclosure into two parts. I dip or immerse the rim, projection, edge, or
end of one part into a recess or hollow in or upon the other part, in which
recess or hollow I place or put either a fluid or dissolved substance, or I place

page_text: a cushion or padding, or any soft compressible elastic or susceptible material,
compound, or substance on one part, upon or into which I rest, press, or force
the other part. In positions or under circumstances which would prevent the
separation at the said parts of junction, I effect it by using a stuffing-box, fluid-
joint, or any air-tight slide, to which I attach one of the parts of the enclosure
which I move up and down; and if requisite, I perform this operation by the
means of a rack and pinion or a screw.
The object and effect of my Invention is, that light or heat may or shall be
attained in a building without any diminution or deterioration of the atmo-
sphere thereof, combustion being supported by air from entirely without, and
the products of combustion being carried off through a pipe or tube above if
lighter than the atmosphere, and falling through a pipe or tube or other
enclosed space below if heavier, to the- exterior of the building, the interior
being entirely free from contamination by the agents or products of heat or
illumination, and I claim as new, the enclosure of the place or space of com-
bustion, the introduction of the air external to the building only into 'the said
enclosure, and the 'prevention of the intrusion to the said enclosure of the air
within the building.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Batten Walmsley in the Great Seal Patent Office
on, the 24th July, 1854.,

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
BATTEN WALMSLEY; of Middle Mall, Hammersmith, in, the County of Mid-
dlesex, Iron Merchant, send greeting.
...WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of January, in the year of our Lord
One thousand eight hundred and fifty-four, in the seventeenth year of Her
reign, did, for Herself, Her heirs and, successors, give and grant unto me, the
said Edward Batten Walmsley, Her special licence that I, the said Edward
Batten Walmsley,, my executors, administrators,. and assigns, or such others
as I, the said Edward Batten Walmsley, 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 UTENSILS, IMPLEMENTS, AND APPARATUS FOR THE PURPOSES OF
"

page_text: LIGHTING, HEATING, AND COOKING," upon the condition (amongst others) that I,
the said Edward Batten Walmsley 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 Edward Batten Walmsley, 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:=
I introduce the air - external to a building or apartment through a pipe or
tube, or any other enclosed or confined passage, unto and into a space in
which I intend combustion to take place or to be achieved, which space I
secure from the intrusion of air from within the building or apartment by
means of an appropriate enclosure. For the egress of smoke, vapour, gas, or
any products of combustion, I' attach one end of a pipe or tube to the furnace
chimney or flue, and pass the other end to the exterior of the building or apart-
ment. I obtain access to the said enclosed space or place of combustion by a
division or separation of the enclosure into two or more parts. I either dip or
immerse the rim, projection, edge, or end of one part into a recess or hollow in
or upon the other part, in which recess or hollow I place or put either a fluid,
or a semi-fluid, or a dissolved substance, or I place a cushion or padding,"or
any soft or compressible material, compound, or substance on one part, upon
or into which I rest, press, or force the other part, or I screw one part on
the other, or I use! an air-tight valve, cover, or door for such purpose.
In positions or under circumstances which would prevent the separation or
recession of the parts of the enclosure, I effect it by using a stuffing-box,
fluid-joint, or any air-tight slide, on the exterior of which I attach one of
the parts of the enclosure which I move up and down; and, if requisite, .I
perform this operation by the means of a rack and pinion or a screw.
The object, intention, and effect of my Invention is that light or heat may
or shall be obtained in a building or apartment without any diminution or
deterioration of the air or atmosphere thereof, combustion being supported by
air entirely from without, the products of combustion being carried off through
a pipe or tube to the exterior of the building or apartment, the interior being
entirely free from contamination by the agents or products of heat or illumina-
tion. I claim as new, the: laying on and supply of the air external to the
building or apartment of the furnace chimney or flue, the trough or cistern
attached or connected to the heating or lighting apparatus, the trapping of

page_text: the furnace flue or chimney by the immersion or impression of a part of the
enclosure into or upon a fluid or semi-fluid, or humid, elastic, compressible,
or dissolved substance or material, and the substitution of, an aperture: in the
enclosure to be closed by an air-tight cover, door, or valve,, also the application
of the stuffing-box, fluid-joint, and any other air-tight slide.
