Year: 1860

page_text: LETTERS PATENT to Arthur Jackson, of Liverpool, in the County of
Lancaster, Commission Agent, for the Invention of "IMPROVEMENTS IN
GENERATING STEAM AS ADAPTED TO A CERTAIN ARRANGEMENT OR CONSTRUCTION
OP STEAM ENGINES FOR TRANSMITTING MOTIVE POWER."
Sealed the 28th May 1861, and dated the 1st December 1860.
PROVISIONAL SPECIFICATION left by the said Arthur Jackson at the
Office of the Commissioners of Patents, with his Petition, on the 1st
December 1860.
I, ARTHUR JACKSON, of Liverpool, in the County of Lancaster, Commission
Agent, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN GENERATING STEAM AS ADAPTED TO A CERTAIN ARRANGEMENT OR CONSTRUCTION OF
STEAM ENGINES FOR TRANSMITTING MOTIVE POWER," to be as follows:-
"My Invention relates solely to the generation of steam for the use of steam
engines of a small or somewhat portable description, which also under certain
circumstances, if so required, may be employed in a similar manner in stationary
or fixed engines of a like character.
The Invention consists in the novel application, use, and adaptation of
ordinary coal or cannel gas in combination with atmospheric air to the purpose
of heating the water in a chamber or boiler to evolve steam when combined
with a steam engine, and is particularly applicable for use in docks or shipping
warehouses and other situations where ordinary steam engines connot be
employed by reason of the danger and risk arising from the common coal

page_text: furnaces thereof, which emit smoke, flame, sparks, and are otherwise dangerous,
and without the adaptation of this improvement for generating the steam could
not be so employed, that is to say, I employ a series of jets of gas beneath a
boiler to generate steam therein instead of a fire or furnace as ordinarily
employed, or the gas and heated air arising therefrom may pass around an
arrangement of tubes in a boiler or chamber containing water in a similar
manner to the fire in an ordinary multibular or common locomotive engine
boiler, the improvement consisting simply in the use of gas as an agent for
obtaining steam in boilers of engines of a portable nature, to be used in certain
peculiar situations as described, and thereby to economise space, making the
boiler portable as well as the engine, a result hitherto unattainable with
ordinary coal furnaces, and further to diminish or prevent the occurrence of
accidents by fire, there being no furnace or fire required to the boiler except
the jets of gas, which are readily controlled; it may therefore be employed in
situations not calculated for ordinary boilers, taking the gas or fuel from the
ordinary mains, and regulating or shutting off its supply at any convenient
situation by ordinary means so as to secure the most perfect safety and efficient
adaptation to the purposes required.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Arthur Jackson in the Great Seal Patent Office on the
1st June 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ARTHUR
JACKSON, of Liverpool, in the County of Lancaster, Commission Agent, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Putent, bearing date the First day of December, in the year of our
Lord One thousand eight hundred and sixty, in the twenty-fourth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Arthur Jackson, Her special license that I, the said Arthur
Jackson, my executors, administrators, and assigns, or such others as I,
the said Arthur Jackson, 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 "AN IMPROVEMENT IN GENERATING STEAM AS ADAPTED TO A CERTAIN ARRANGE-

page_text: MENT OR CONSTRUCTION OF STEAM ENGINE FOR TRANSMITTING MOTIVE POWER," upon
the condition, amongst others, that I, the said Arthur Jackson, by an instru-
ment in writing under my hand and seal, sliould 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 Arthur Jackson, 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 and accompanying Drawings (that is to say):-
My Invention relates solely to the generation of steam for the use of steam'
engines of a small or somewhat portable description, which also, under certain
circumstances if so required, may be employed in a similar manner in stationary
or fixed engines of a like character.
The Invention consists in the novel application, use, and adaptation of
ordinary coal or cannel gas or any other inflamable gas in combination with
atmospheric air to the purpose of heating the water in a chamber or boiler to
evolve steam when combined with a steam engine, and is particularly applicable
for use in docks or shipping warehouses and other situations where ordinary
steam engines cannot be employed by reason of the danger and risk arising from
the common coal furnaces thereof, which emit smoke, flame, sparks, and are
otherwise dangerous, and which, without the adaptation of this improvement
for generating the steam, could not with such safety be employed, that is to say,
I employ gas beneath a boiler to generate steam therein instead of a fire or
furnace as ordinarily employed, or the gas and heated air may pass around an
arrangement of tubes in a boiler or chamber containing water in a similar manner
to the fire in an ordinary multitubular boiler, the improvement consisting
simply in the use of gas as an agent for obtaining steam in boilers of a portable
description, to be used in certain peculiar situations as described. I am
thereby enabled to diminish or prevent the occurrence of accidents by fire,
there being no furnace or fire required to the boiler except the gas which is
readily controlled, taking the gas or fuel from the ordinary mains and regu-
lating or shutting off its supply at any convenient situation by ordinary means
so as to secure the most perfect safety and efficient adaptation to the purposes
required.
In order that the Invention may be better understood and explained in
detail I have hereunto attached a Sheet of Drawings illustrative of the

page_text: Fig. 1 is a sectional view taken vertically through the boiler, and Fig. 2 is a
plan view taken above wire gauze, which is shewn as partly removed, to
exhibit one of the arrangements I employ to consume the gas.
In Fig. 1, a, a, is the exterior casing of the boiler; b, b, are the tubes whence
the gas issues; and c the wire gauze where it is ignited after being mixed
with atmospheric air in the chamber d. Upon the gauze pumice stone or
other heat-retaining material may be placed if required; e, e, is the space and
tubes containing water from which steam is evolved.
Another method is by employing a series of fire-clay tubes or burners having
numerous perforations, the gas entering the tube at the lower end.
Having now described the nature of the said Invention, together with the
best methods with which I am at present acquainted for carrying the same
into practical effect, I would remark in conclusion that I do not confine
myself to the precise details, but I wish it to be understood that I claim the
novel application and adaptation of any combustible gas in combination with
atmospheric air for obtaining steam in boilers of a portable description, and
for the peculiar purposes herein-before described, set forth, and exhibited in
the Drawings attached.
In witness whereof, I, the said Arthur Jackson, have hereunto set my
hand and seal, this Thirty-first day of May, in the year of our
Lord One thousand eight hundred and sixty-one.
ARTHUR JACKSON.
