IMPROVEMENTS IN APPARATUS TO BE USED IN CONNECTION WITH FURNACES FOR BURNING CREOSOTE AND OTHER COMBUSTIBLE LIQUIDS
Year: 1868

page_text: LETTERS PATENT to Augustus Smith, of Stratford, in the County
of Essex, for the Invention of "IMPROVEMENTS IN APPARATUS TO BE
USED IN CONNECTION WITH FURNACES FOR BURNING CREOSOTE AND OTHER
COMBUSTIBLE LIQUIDS."
Sealed the 28th October 1868, and dated the 2nd May 1868.
PROVISIONAL SPECIFICATION left by the said Augustus Smith at
the Office of the Commissioners of Patents, with his Petition, on
the 2nd May 1868.
I, AUGUSTUS SMITH, of Stratford, in the County of Essex, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
APPARATUS TO BE USED IN CONNECTION WITH FURNACES FOR BURNING CREOSOTE
AND OTHER COMBUSTIBLE LIQUIDS," to be as follows:-
My Invention relates to improvements in apparatus to be used in
connection with furnaces for burning creosote and other combustible
liquids. For this purpose I lead the creosote or liquid from any convenient
reservoir by a pipe to the front of the furnace. The terminal end of

page_text: this pipe is horizontal or nearly so, and extends through an aperture
in the furnace door or front plate. In the horizontal portion of the
liquid pipe I introduce the terminal horizontal end of a steam pipe;
the horizontal portion of the steam pipe is preferably concentric with
the horizontal portion of the liquid pipe, but does not extend so far
into the furnace. The pipes are provided with taps or cocks for
regulating the supply of the liquid and steam respectively. When
both pipes are open the stream of liquid as it pass from the annular
space between the steam pipe and the liquid pipe is struck by the jet
of steam and becomes thoroughly mixed therewith before issuing from
the open end of the liquid pipe; the open end of this pipe is
preferably contracted. The liquid and steam thus enter the furnace
together in a highly divided state and the liquid is consumed therein.
The important feature of my Invention is that the steam jet issues
in the middle of the stream of the liquid before the liquid reaches the
end or outlet of its pipe.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Augustus Smith in the Great Seal Patent Office
on the 2nd November 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, AUGUSTUS
SMITH, of Stratford, in the County of Essex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Second day of May, in the year
of our Lord One thousand eight hundred and sixty-eight, in the thirty-
first year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Augustus Smith, Her special licence that I,
the said Augustus Smith, my executors, administrators, and assigns,
or such others as I, the said Augustus Smith, my executors, adminis-
trators, 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 APPARATUS

page_text: TO BE USED IN CONNECTION WITH FURNACES FOR BURNING CREOSOTE AND OTHER
COMBUSTIBLE LIQUIDS," upon the condition (amongst others) that I, the
said Augustus Smith, 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 Augustus Smith, 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 thereof, reference being had to the Drawings
hereunto annexed, that is to say :-
My Invention relates to improvements in apparatus to be used in
connection with furnaces for burning creosote and other combustible
liquids. For this purpose I lead the creosote or liquid from any
convenient reservoir by a pipe to the front of the furnace. The
terminal end of this pipe is horizontal or nearly so and extends through
an aperture in the furnace door or front plate. In the horizontal
portion of the liquid pipe I introduce the terminal horizontal end of
a steam pipe; the horizontal portion of the steam pipe is preferably
concentric with the horizontal portion of the liquid pipe, but does not
extend so far into the furnace. The pipes are provided with taps or
cocks for regulating the supply of the liquid and steam respectively.
When both pipes are open the stream of liquid as it passes from the
annular space between the steam pipe and the liquid pipe is struck
by the jet of steam and becomes thoroughly mixed therewith before
issuing from the open end of the liquid pipe. The open end of this
pipe is preferably contracted. The liquid and steam thus enter the
furnace together in a highly divided state and the liquid is consumed
therein.
My Invention will be fully understood by the accompanying

page_text: a is a portion of the furnace or furnace flue; and b is the
furnace door or front plate; is a pipe leading from a reservoir
containing the combustible liquid to the front of the furnace where
it terminates in a horizontal portion d, which passes through an
aperture in the door b. The end e of this pipe is open and
contracted, as shown. f is a steam pipe supplied with steam from
the boiler or otherwise; by preference this pipe leads from the
steam space of the boiler down through the water and out at the
lower part of the front plate of the boiler, from which it is carried up
to the front of the furnace ; this pipe likewise terminates in a
horizontal portion 9 which is fitted concentrically in the portion d of
the liquid pipe, but does not extend so far into the furnace. h is an
orifice at the end of the portion g of the steam pipe; beyond this orifice
the portion g is cup-shaped, as seen at i; the steam which issues by
the orifice becomes spread in passing through this cup; k is a cock
or tap to regulate the supply of the liquid; and a cock or tap to
regulate the supply of the steam. When both pipes are open the
stream of liquid fills the annular space between the portion d of
the liquid pipe and the portion g of the steam pipe, and as it passes
from this space to beyond the cup i it is struck in the middle or
centre by the jet of steam and becomes thoroughly mixed therewith
before issuing from the contracted portion e into the furnace. The
liquid and steam thus as before stated enter the furnace together in
a highly divided state.
Figure 2 is a view of the inner end of the horizontal portion g of
the steam pipe; in this Figure and in Figure 1 only one orifice for
the steam is shewn; but any desired number of such orifices may be
employed, for instance, nine, as shown in Figure 3.
My apparatus does not necessitate any alteration in the furnace or
flue; any proportions of coal or coke and combustible liquid may be
consumed therein as found convenient; when only liquid is used I
find it advantageous to employ brick core for the liquid and steam to
impinge against.
My apparatus is particularly appliable to steam ships, owing to the
proportionately small quantity of combustible liquid required to produce
a given amount of heat.

page_text: The important feature of my Invention is that the steam jet issues
in the middle or centre of the stream of the liquid before the liquid
reaches the end or outlet of its pipe.
In witness whereof, I, the said Augustus Smith, have hereunto set
my hand and seal, this Thirty-first day of October, One thousand
eight hundred and sixty-eight.
AUGUSTUS SMITH. (L.s.)
