Year: 1872

page_text: LETTERS PATENT to Louis Simon and Richard Simon, both of the
Town and County of the Town of Nottingham, for the Invention of
"A NEW OR IMPROVED METHOD OF APPLYING PETROLEUM PRODUCTS TO
ILLUMINATING PURPOSES, AND APPARATUS BELONGING THERETO."—A com-
munication from abroad by William Sommerfeld, of Vienna, in the
Empire of Austria.
Sealed the 17th June 1873, and dated the 20th December 1872.
PROVISIONAL SPECIFICATION left by the said Louis Simon and
Richard Simon at the Office of the Commissioners of Patents, with
their Petition, on the 20th. December 1872.
We, LOUIS SIMON and RICHARD SIMON, both of the Town and County
of the Town of Nottingham, do hereby declare the nature of the said
Invention for "A NEW OR IMPROVED METHOD OF APPLYING PETROLEUM PRO-
DUCTS TO ILLUMINATING PURPOSES, AND APPARATUS BELONGING THERETO," (a
communication to us from abroad by William Sommerfeld, of Vienna,
in the Empire of Austria) to be as follows:-
We take one of the products of the distillation of petroleum, such as
naphtha, gazoline, or any other suitable hydrocarbon, and by means of a

page_text: suitable apparatus cause a current of atmospheric air to pass over it or
through it in such a manner that the air becomes strongly charged with the
vapour of the hydrocarbons. We then conduct this air mixed with the
vapour of the hydrocarbon into a suitable receptacle, whence it is con-
ducted through ordinary pipes to the ordinary burners, or to the burners
made on purpose. The burners are divided by screws in order to obtain
a stronger current of air, by which the flame becomes better adapted for
beating or smelting purposes. And, further, that independently of these
specially constructed burners all burners generally used can be used in
connection with the apparatus, both kinds of burners giving a cheaper
and superior light than that obtained by the use of coal gas.
The apparatus consists of a box made of tin or other suitable material
divided into various compartments, one of which is the reservoir for
hydrocarbon, which compartment is again divided into smaller compart-
ments to facilitate the evaporation by means of sponges or other materials,
and also shews the quantity contained in it, and is also provided with.
locks or taps for regulating the same in it.
Another compartment forms a reservoir for water which exercises a
pressure upon the atmospheric air; another compartment contains some
fans or other suitable machinery worked by weights to create the current
of air to be mixed with the hydrocarbon.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Louis Simon and Richard Simon in the Great Seal
Patent Office on the 19th June 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, LOUIS 2
SIMON and RICHARD SIMON, both of the Town and County of the Town
of Nottingham, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of December, in the year of our
Lord One thousand eight hundred and seventy-two, in the thirty- 30
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Louis Simon and Richard Simon, Her
special licence that we, the said Louis Simon and Richard Simon,
our executors, administrators, and assigns, or such others as we, the

page_text: "
the said Louis Simon and Richard Simon, our 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 "A NEW OR IMPROVED METHOD OF
APPLYING PETROLEUM PRODUCTS TO ILLUMINATING PURPOSES AND APPARATUS
BELONGING THERETO," a communication to us from abroad by William
Sommerfeld, of Vienna, in the Empire of Austria, upon the condition
(amongst others) that we, the said Louis Simon and Richard Simon, our
executors or administrators, by an instrument in writing under our, 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 we, the said Louis Simon and Richard Simon
do hereby declare the nature of our 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) :-
We take one of the products of the distillation of petroleum, such
as naphtha, gazoline, or any other suitable hydrocarbon, and by means
of a suitable apparatus cause a current of atmospheric air to pass over it
or through it in such a manner that the air becomes strongly charged
with the vapour of the hydrocarbon. We then conduct this air mixed
with the vapour of the hydrocarbon into a suitable receptacle, whence it
is conducted through ordinary pipes to the ordinary burners, or to the
burners made on purpose. The burners are divided by screws in order
to obtain a stronger current of air, by which the flame becomes better
adapted for heating or smelting purposes. And, further, that inde-
pendently of these specially constructed burners, all burners generally
used can be used in connection with this apparatus, both kinds of burners
giving a cheaper and superior light than that obtained by the use of
coal gas.

page_text: hydrocarbon (marked a on the Drawings), which compartment is again
divided into smaller compartments to facilitate the evaporation by means
of sponges or other materials, and also shews the quantity contained in
it, and is also provided with cocks or taps for regulating the same in it.
Another compartment R forms a reservoir for water which exercises 5
a pressure upon the atmospheric air; another compartment (marked C
in the Drawings) contains some fans or other suitable machinery worked
by weights to create the current of air to be mixed with the hydro-
carbon.
And in order that my said Invention may be more fully understood, 1
I will proceed to describe the same, reference being had to the annexed
Sheets of Drawings, Nos. 1 and 2, and to the letters and figures marked
thereon, the same letters referring to like parts throughout, that is to
say:―
Sheet No. 1, Fig. 1, shews an external view of the apparatus; Sheet 1
No. 2, Fig. 2, a sectional view of same.
a (Fig. 1, Sheet 1, see also Fig. 2) is the reservoir for the hydrocarbon;
b, b, (Fig. 1) is a glass gauge shewing the quantity contained in the
same; c is the compartment to be used for the fans forming the reservoir
for the water; w is a sort of tap for opening or closing the apparatus ; a
f9, are the pipes belonging to it; % is the pipe connecting the apparatus
with the regular gas pipes; o, p, are two taps (Fig. 1) to supply the
lower parts of the apparatus with the hydrocarbon; R, S, (Fig. 1) are
two glass windows to shew how much hydrocarbon is in this lower part
of the apparatus; U, U, (Fig. 1) are two taps to let the hydrocarbon run
out for cleaning the apparatus; d (Fig. 1) is a coil of string for moving
the fan; and e (Fig. 1) is the weight.
In Fig. 2 will be seen p¹ and p³, which are pipes conveying the gás
into the regulator; R, the regulator; x¹and r³ are small air escape pipes
from the lower chambers into the space a.
Having thus described the nature of this our said Invention, and the
mode of carrying the same into effect, what we claim and desire to be
secured to us by Letters Patent are,—
First. The particular way by which illuminating gas is produced by
mixing the vapours of petrolcum or other similar materials with
