Year: 1873

page_text: LETTERS PATENT to John Carter Ramsden, of Lightcliffe, in the
County of York, Silk Manufacturer, for the Invention of "IMPROVED
APPARATUS FOR GENERATING STEAM, ECONOMISING FUEL, AND UTILIZING THE
GASES ARISING FROM THE COMBUSTION THEREOF.'
Sealed the 19th May 1874, and dated the 21st November 1873.
PROVISIONAL SPECIFICATION left by the said John Carter Ramsden
at the Office of the Commissioners of Patents, with his Petition,
on the 21st November 1873.
I, JOHN CARTER RAMSDEN, of Lightcliffe, in the County of York,
Silk Manufacturer, do hereby declare the nature of the said Invention
for "IMPROVED APPARATUS FOR GENERATING STEAM, ECONOMISING FUEL, AND
UTILIZING THE GASES ARISING FROM THE COMBUSTION THEREOF," to be as
follows:-
This Invention has for its objects the construction of steam boilers
more especially designed for use in connection with liquid fuel, there
being provision made for warming or heating the air supplied to the

page_text: combustion chamber, and the gases arising from combustion are after
leaving the flue or flues or tubes of the boiler further utilized.
I employ a boiler of the multitubular description and locomotive
type.
وو
In addition to the ordinary horizontal tubes I employ a number of
vertical tubes, (which to allow for expansion and contraction may be
curved) arranged within what has heretofore served as the "fire-box.'
The vertical tubes are connected with the water and steam spaces under
and above the "fire-box."
-
In front of and attached to and communicating with which said “fire-
box," is one or more small steam boilers or enlargements of the "fire-
box," the heat being generated and applied to the small boiler or boilers
(as and by the apparatus described in the Specification of Letters Patent
granted to me, No. 873, in the year of our Lord 1873). The heated
gases after passing around and between the vertical tubes, and thence by
way of the horizontal tubes may pass off when not required, but
generally they are to be utilized by being passed around the boiler or
taken direct by means of a fan or pump, and forced into water contained
in a vessel from which the feed water for the boiler is to be taken.
hot gases of combustion on passing from the boiler to the fan pass
through perforations in moveable slabs of fire-clay or metal; the atmos-
pheric air required in the combustion chamber passes through the
perforated slabs, and by way of a pipe or pipes to the combustion
chamber, and so become heated or warmed before admitted.
The
The gases not absorbed by the water may by means of pumps be
forced through any of the well known volatile illuminating oils or spirits
and passed into a gas holder. It is better however such gases should be
heated again after leaving the water by being passed through perforated
hot slabs or pipes, because hot gases so passed through spirits give the
best results.
When coal or other solid fuel is used, the gases of combustion will be
nassed into the feed water as previously described

filed by the said John Carter Ramsden in the Great Seal Patent
Office on the 21st May 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
CARTER MARSDEN, of Lightcliffe, in the County of York, Silk Manu-
facturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of November, in the
year of our Lord One thousand eight hundred and seventy-three, in
the thirty-seventh year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said John Carter Ramsden,
Her special licence that I, the said John Carter Ramsden, my executors,
administrators, and assigns, or such others as I, the said John Carter
Ramsden, 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 "IMPROVED APPARATUS FOR GENERATING STEAM, ECONOMISING
FUEL, AND UTILIZING THE GASES ARISING FROM THE COMBUSTION THEREOF,"
upon the condition (amongst others) that I, the said John Carter
Ramsden, 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 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 John Carter Ramsden, 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, that is to say :-
This Invention has for its objects the construction of steam boilers
more especially designed for use in connection with liquid fuel, and the
gases arising from combustion are after leaving the flue or flues or tubes
of the boiler further utilized,

page_text: A is the boiler; it is provided with five (or other number) of boxes B
within which the gases are generated, as afterwards herein described;
C are fire-tubes leading to the combustion chamber D in which are
vertical water tubes E connecting lower and upper waterways; F, F, are
fire-tubes leading to the smoke box G; H is a funnel for discharge of
product of combustion when not required to be utilized; J is a pipe
connecting the smoke box with the blower or fan J', where the products
of combustion are to be further dealt with. At K is a pipe communi-
cating with the steam space of the boiler; from this pipe extend others
K³, K, K³, and K*; from the pipe K¹ the coiled and perforated pipes L
are supplied with steam from Kare like coiled and perforated pipes L³,
from pipes K and K³, branch nozzle pipes M terminating in very small
apertures, these pipes discharge steam on to and immediately over thic
capillary orifices of the tubes N branching from the pipes N1, N2; the
latter pipes are supplied with spirits of petroleum or refined oil of
petroleum (the latter being preferable) from the reservoir or closed
tank N³.
The operating is as follows:-The screw valves a, b, of the steam
pipes are opened so likewise the tap c admitting the oil of petroleum, the
petroleum which becomes mingled in minute sub-division with the steam
in the generator B on a light being applied, the steam is decomposed by
reason of the intensity of heat creating a gas which passes by way of the
pipe C to the combustion chamber D. The grating D' admits atmospheric
air whereon the gases are burnt within the said combustion chamber,
the flame impinging on and circulating around the virtical water way
tubes E when considerable heat is obtained in the generator B and pipes
C, the screw valves a, b, will be opened discharging steam through the
perforations of the coils L, L', the gases or results of this combustion
pass by way of the pipe J to the fan or blower J', thence (if required for
illuminating purposes) are passed through water contained within an
enclosed tank, afterwards forced through any of the well known
illuminating spirits, such as spirits of petroleum. The water may be used
for boiler feed purposes. If the gases the result of combustion are not
required for illunination but for heating purposes, then they are dis-
charged by the fan or blower J'along a pipe W, which pipe is in
communication by the pipe e with a vesself containing oil of petrolium
heated by waste steam or other means so as to vapourize the same, the
vapours mingle with the gases which are then applied for heating
nurno008

page_text: The gases arising from the combustion of coal or other solid fuel are
also available for treatment by being passed through water, and after-
wards impregnated or charged with the vapour arising from oil or spirit of
petrolium, as and by the apparatus already described and shewn at
Fig. 5, so rendering such gases available for heating purposes; but the
gases from the liquid fuel are specially valuable for the smelting,
melting, refining, or converting metals not only by reason of the
complete absence of sulphur and phosphorous, but by reason of the
inherent properties possessed by gases made as above described.
I would have it understood that I lay no claim to the apparatus for 1
supplying the liquid fuel to the boxes or generators B, nor to the use of
volatile oils or spirits for illuminating the gases arising from com-
bustion.
In witness whereof, I, the said John Carter Ramsden, have here-
unto set my hand and seal, this Nineteenth day of May, One 1
thousand eight hundred and seventy-four.
