Year: 1873

page_text: LETTERS PATENT to Charles Tysoe, of Salford, in the County of
Lancaster, Cotton Spinner, for the Invention of "IMPROVEMENTS IN
MEANS FOR SUPPLYING TAE, -OIL, CREOSOTE SPIRIT, OR OTHER IGNITIBLE
FLUID OR FATTY MATTER TO FURNACES, AND FOR PROMOTING THE COMBUSTION
OF SUCH MATTERS.”
Sealed the 24th February 1874, and dated the 30th August 1873.
PROVISIONAL SPECIFICATION left by the said Charles Tysoe at the
Office of the Commissioners. of Patents, with his Petition, on the
30th August 1878.
I, CHARLES TYSOE, of Salford, in the County of Lancaster, Cotton
Spinner, do hereby declare the nature of the said Invention for "Im-
PROVEMENTS IN MEANS FOR SUPPLYING TAB, OIL, CREOSOTE SPIRIT, OR OTHER
IGNITIBLE FLUID OR FATTY MATTER TO FURNACES, AND FOR PROMOTING THE
COMBUSTION OF SUCH MATTERS," to be as follows:-
My Invention relates more particularly to the furnaces of steam
generators, and has for its object to render more advantageous the

page_text: employment in such furnaces of tar, rock oil, creosote spirit, palm oil,
and other oleaginous fatty or ignitible fluid matters in lieu of coal. To
supply such matters to the furnaces I employ jets of compressed air,
which inject the said matters into the said furnaces in the form of spray,
and effect the distribution of the same.
I may employ hollow fire-bars, and eject the oil or other matter
through perforations or nozzles in the sides of the said bars by means of
compressed air.
In lieu of coke, which has previously been employed to retain heat
within the furnace, and to promote the. combustion of oil or creosote, I 1
make use of fire-clay moulded into suitable shapes, such as for example
cones, balls, or cubes, either with or without perforations, or I make
use of pieces of chalk, scrap iron, pumice stone, or of prepared
pumice stone.
I may so arrange the furnace as that a bed or layer of fire-clay, 1
lumps, or of pieces of chalk, scrap iron, or pumice stone, or of two or
more of the said materials shall extend the whole or nearly the whole
length of the boiler or of the internal flue..
I propose to use palm oil, butter, tallow, lard, and other similar fatty
matters when such can be obtained at a sufficiently low cost, the said 2
matters being melted in a tank fitted with a steam coil or with steam
pipes to render them suitable to be supplied to the furnace in the
manner herein-before indicated, or other means may be employed to
melt the said matters.

page_text: 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 Charles Tysoc, Her special license that I, the
said Charles Tysoe, my executors, administrators, and assigns, or such
5 others as I, the said Charles Tysoc, 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 King-
dom of Great Britain and Ireland, the Channel Islands, and Isle of
0 Man, an Invention for "IMPROVEMENTS IN MEANS FOR SUPPLYING TAR, OIL,
CREOSOTE SPIRIT, OR OTHER IGNITIBLE FLUID OR FATTY MATTER TO FURNACES,
AND FOR PROMOTING THE COMBUSTION OF SUCH MATTERS," upon the condition,
amongst others, that I, the said Charles Tysoe, by an instrument in
writing under my hand and seal, should particularly describe and
5 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
Scal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Charles Tysoe, do hereby declare
O 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 more particularly to the furnaces of steam
generators, and has for its object to render more advantageous the
5 employment in such furnaces of tar, rock oil, creosote spirit, palm oil,
and other oleaginous fatty or ignitible fluid matters in lieu of coal. To
supply such matters to the furnaces I employ jets of compressed air,
which inject the said matters into the said furnaces in the form of spray,
and effect the distribution of the same.
) I may employ hollow fire-bars, and eject the oil or other matter
through perforations or nozzles in the sides of the said bars by means of
compressed air.
In lieu of coke, which has previously been employed to retain heat
within the furnace, and to promote the combustion of oil or creosote, I
5 make use of fire-clay moulded into suitable shapes, such as for examplo

page_text: cones, balls, or cubes, cither with or without perforations, or I make
use of pieces of chalk, scrap iron, limestone, pumice stone, or of
prepared pumice stone.
I may so arrange the furnace as that a bed or layer of fire-clay
lumps or of pieces of chalk, scrap iron, limestone, pumice stone, or of
prepared pumice stone. I may so arrange the furnace as that a bed or
layer of fire-clay lumps or of pieces of chalk, scrap iron, limestone, or
pumice stone, or of two or more of the said materials shall extend the
whole or nearly the whole length of the boiler or of the internal flue.
I propose to use palm oil, butter, tallow, lard, and other similar fatty
matters when such can be obtained at a sufficiently low cost, the said
matters being melted in a tank fitted with a steam coil or with steam
pipes to render them suitable to be supplied to the furnace in the
manner herein-before indicated, or other means may be employed to
melt the said matters.
And in order that my said Invention may be fully understood, I have
furnished a Sheet of Drawings made to a scale of about one-eighth of
the full size, and indicating the manner in which I may apply my said
Invention to an ordinary Cornish boiler. The said Drawings to which
I will immediately refer are marked with letters of reference, similar
marks indicating the same parts in the various Figures.
⋅
Fig. 1 represents a vertical longitudinal section of the furnace end of
a boiler, and Fig. 2 a horizontal section taken at about the centre line
of the furnace.
In the said Figs., or in one of them, a is the shell of the boiler; bis
the shell of the furnace; c, indicates the ordinary fire-bars; and d, a
layer or bed consisting of one or more of the substances herein-before
mentioned. On one side of the furnace doorway is fixed a vertical
pipe e, which is connected with a pipe which furnishes a supply of
creosote or other liquid fuel, and on the other side of the said doorway
is fixed a second vertical pipe f, which is connected with a pipe which
supplies a blast of air derived from a fan or, pump or otherwise created.
Each of the said vertical pipes is provided with a valve, as indicated at
g in Fig. 3, and on the top of each pipe is mounted an liollow arm, each
arm being fitted to swivel on the vertical pipe, so that the said arms can
be readily moved into position within the doorway or be swung round

page_text: so as to leave the said doorway free from obstruction. The arm h
terminates in a mouth, from which the liquid fuel is permitted to flow,
and the arm i also terminates in a mouth, through which a blast of air
issues to disperse the said fuel and to inject the same into the furnace,
and also to aid in effecting the combustion of the same.
:
The proportions and forms of the said mouths and the arrangements
of the supply pipes may be varied as desired, or as may be required to
suit varying circumstances, and two or more mouths for the supply of
liquid fuel, and two or more blasts or jets of air may be employed in
connection with one furnace if considered to be or found to be necessary
or suitable.
:
Figs. 4 and 5 illustrate a form and arrangement of hollow fire-bars
for supplying air and liquid fuel to a furnace as herein-before mentioned,
Fig. 4 being a plan, and Fig. 5, a vertical cross section drawn to a larger
scale than Fig. 4. In this example both the liquid fuel and the air blast
are conveyed by the pipe k, with which the ends of all the hollow fire-
bars indicated by 1, 1, are in connection. The said liquid fuel flows into
the said fire-bars until it rises to the level of inclined perforations m, m,
formed in the sides of the said bars when the said fuel becomes gradually
"taken up" by the blast of air issuing from the said perforations, and
is thereby injected into the furnace in the form of spray along with the
air.
.
I may admit the liquid fuel into the hollow bars through a pipe
connected with one end of each bar, and the air through a pipe con-
nected with the other end of the bar. The said hollow bars may be
made otherwise than circular in cross section.
Having now fully described the nature of my Invention, and means
for carrying the same into practical effect, I would have it to be under-
stood in conclusion that I claim.—

And, lastly. The employment of hollow bars, substantially as and for
purpose herein set forth and indicated.
In witness whereof, I, the said Charles Tysoe, have hereunto set
my hand and seal, this Twenty-seventh day of February, in the
year of our Lord One thousand eight hundred and seventy- &
four.
