PROVISIONAL SPECIFICATION left by the said James Standfield at the
Office of the Commissioners of Patents, with -his- Petition, on the
16th December 1867.
I, JAMES STANDFIELD, of Betchworth, in the County of Surrey, do bereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE MEANS,
OF AND APPARATUS FOR OBTAINING AND APPLYING HYDROGEN GAS TO THE FURNACES
OF STEAM ENGINES, BOILERS, AND KILNS FOR. THE MANUFACTURE OF BRICKS AND.
LINE, to be as follows:-
My Invention consists of improvements in the means of and apparatus for ob-
taining and applying hydrogen gas to the furnaces of steam engines, boilers, and
kilns for the manufacture of bricks and lime, and to this end I construct the
said furnaces with a suitable chamber of any convenient shape and placed in
any convenient position, through which chamber I pass steam, causing it thereby
to be decomposed, and thus supply hydrogen gas to the said furnaces, the
main objects in view being the economy of fuel, prevention of smoke, and

page_text: ready transmission of heat from the said furnaces, and removal of carbonic
acid gas & other deliterious matters from the substances, with which kilns.
are charged to, which my Invention is applied. The introduction of the
said hydrogen gas is made in all cases above the fuel consumed in such
furnaces, and all air is carefully excluded which does not pass through the
fuel.
I do not confine myself to any special form of chamber in which the
decomposition of the steam takes place, nor to any special pressure of steam;
but I prefer that the said gas should issue in fine steams from the chamber
I employ, & that the currents be directed directly towards the tubes. or
flues with which the furnaces may be in connection..
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
:
by the said James Standfield in the Great Seal Patent Office on the
16th June 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
STANDFIEILD, of Betchworth, in the County of Surrey, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of December, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said James Standfield, Her special licence that I, the said James.Stanfield,
my executors, administrators, and assigns, or such others as I, the said James
Standfield, 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 THE MEANS
OF AND APPARATUS FOR OBTAINING AND APPLYING HYDROGEN GAS TO THE FURNACES
OF STEAM ENGINES, BOILERS, AND KILNS FOR THE MANUFACTURE OF BRICKS AND
LINE," upon the condition (amongst others) that I, the said James Stanfield,
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,

page_text: NOW KNOW YE, that I, the said James Standfield, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
My Invention consists in the means of an apparatus for obtaining and
applying hydrogen gas to the furnaces; of steam engines, boilers, and kilns for
the manufacture of bricks and lime, and to this end I construct the said
furnaces with a suitable chamber of any convenient shape, and placed in any
convenient position, through which chambers I pass steam, causing it thereby
to be decomposed, and thus supply hydrogen gas to the said furnaces, the
main objects in view being the economy of fuel, prevention of smoke, and
ready transmission of heat from the said furnaces and removal of carbonic
acid gas and other deleterious matters from the substances with which all kilns.
are charged to which my Invention is applied. The introduction of the
said hydrogen gas is made in all cases above the fuel consumed in such
furnaces, and all air is carefully excluded which does not pass through the
fuel.
I do not confine myself to any special form of chamber in which the
decomposition of the steam takes place, nor to any special pressure of steam;
but I prefer that the said gas should issue in fine streams from the chamber
I employ, and that the currents be directed directly towards the tube or tubes
with which the furnaces may be in connection.
.
In the foregoing description of my Invention I have spoken of steam alone
as being admitted into the chamber in order that it may be decomposed; but
I would have it understood that water, when very finely divided or in the
form of spray, or water produced from condensation of steam in the pipes,
may be in like manner employed in certain cases, the water thus minutely
divided being passed into the chamber, where it will be decomposed in th
some manner as steam.
.But in order that my Invention may be more readily understood and
carried into effect I will now describe the means of performing the same,
reference being had to the accompanying Drawings.
Figure 1 shows the application of my Invention to an ordinary Cornish
boiler, and Figure 2 the section of the chamber, which may be attached to any
existing furnace door; this chamber is perforated with a number of small
holes a, a, a, through which the gases escape into the furnace. The tube b
is so arranged in connection with the stop-cock or swivel joint c that when
the door is opened for the purpose of firing the cock c is closed. The
stop-cock d is for the purpose of regulating the supply according to the

page_text: requirements of the furnace. To allow of the furnace door opening the
axis of the cock c must be in the same line as that upon which the door
turns..
Figure 3 shews a modification in which two fixed chambers are arranged,
one on either side of a furnace, both being supplied from one pipe fitted with
regulating cock, as before described.
Figure 4 shews the same arrangement as Figs. 1 and 2, but applied to
an egg-ended boiler..
Figure 5 shews the front of an ordinary kiln, and Figure 6, a section of
the furnace of the same, the chamber being attached to the door by flanges.
Figure 7 shows a modified form of chamber screwed to the furnace
door, an opening being made through the neck for the passage of the steam
pipe.
I have not thought it necessary to shew Drawings of the arrangements as
applied to other classes of furnaces, as it will be seen whether fitted to
locomotives, portable or other steam engines, as also to marine and stationary
boilers, it is precisely the same in principle. As already described the steam
employed need not be of any special pressure, being supplied by the boiler to
which my Invention is applied. In the case of brick or lime kilns a separate
boiler must be employed, pipes being lead to the several furnaces. The steam
may be used in its ordinary state, or it may be superheated in the ordinary
manner before passing into the decomposing chamber, or in some cases water
may be employed in a finely divided state, as already described.
Having now described the nature of my Invention, and the manner the
same may be performed, I wish it to be understood that I do not confine
myself to the precise details shewn in the accompanying Drawings; but I
claim the mode of producing and applying hydrogen gas to the furnaces of
steam engines, boilers, and kilns for the manufacture of bricks and lime,
substantially as herein-before described.

In witness whereof, I, the said James Standfield, have hereunto set my
hand and seal, this Sixteenth day of June, One thousand eight
hundred and sixty-eight.
JAMES STANDFIELD. (L.s.)
