Year: 1872

page_text: LETTERS PATENT to Edward Primerose Howard Vaughan, F.C.S., of
54, Chancery Lane, in the County of Middlesex, Patent Agent, for
the Invention of "IMPROVEMENTS IN THE MODE OF AND APPARATUS FOR
GENERATING GAS FOR LIGHTING AND HEATING PURPOSES."-A com-
munication from abroad by Eugéne Albert Dubois, residing at Paris,
in the Republic of France.
PROVISIONAL SPECIFICATION left by the said Edward Primerose
Howard Vaughan at the Office of the Commissioners of Patents,
with bis Petition, on the 28th October 1872.
I, EDWARD PRIMEROSE HOWARD VAUGHAN, F.C.S., of 54, Chancery
Lane, in the County of Middlesex, Patent Agent, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN THE MODE OF
AND APPARATUS FOR GENERATING GAS FOR LIGHTING AND HEATING PURPOSES,"
being a communication to me from abroad by Eugéne Albert Dubois,
residing at Paris, in the Republic of France, to be as follows:-
This Invention has for its object the extraction of gas for lighting and
heating from the liquid hydrocarbon known as "gasoline," by means

page_text: of improved apparatus, as shewn by the accompanying Drawing, in
which Figure 1 is a longitudinal section, and Figure 2 an end view.
A, A¹, represent a cast-iron cylinder divided into two equal spaces or
compartments by the central partition B in copper or brass, and closed
by the plates C, C, secured by the bolts D, D. In the axis of this
cylinder is mounted a hollow wrought-iron shaft E revolving in the
bearings F, G; H is a spiral shell or volute formed of sheet copper or
brass, set on the shaft E in the compartment A of the cylinder, and on
the other half of the shaft in the compartment A' is set a haircloth drum J
covered with a porous fabric, such as linen. K is a funnel by which
the cylinder A, A', is charged with gasoline up to about the level of the
shaft E; M is a passage formed in the partition B; N is a glass gauge;
O is a pulley mounted on the prolongation of the shaft E, and driven by
the band o' from the second pulley Q set on the shaft of the wooden
roller P. On this roller is wound the cord p, the free end of which
passed through the blocks R carries the driving weight S. The upper.
part T of the cylinder A', A¹, is filled with air, which, in the working of
the apparatus, is forced through the spiral canals of the volute H, and
thence by the hollow shaft.E through the saturated porous material J, and
thus converted into inflammable gas passes through the outlet pipe V to
be distributed as may be required.
The form, dimensions, and general details of construction of the
apparatus may be modified according to circumstances.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Primerose Howard Vaughan in the Great
Seal Patent Office on the 19th April 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD.
PRIMEROSE HOWARD VAUGHAN, F.C.S, of 54, Chancery Lanc, in the
County of Middlesex, Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of October, in
the year of our Lord One thousand eight hundred and seventy-two, in
the thirty-sixth year of Her reign, did, for Herself, Her heirs and

page_text: successors, give and grant unto me, the said Edward Primerose Howard
Vaughan, Her special license that I, the said Edward Primerose Howard
Vaughan, my executors, administrators, and assigns, or such others as I,
the said Edward Primerose Howard Vaughan, my executors, ad-
ministrators, 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 MODE OF AND APPARATUS FOR GENERATING GAS FOR LIGHTING AND HEATING
PURPOSES," a communication to him from abroad by Eugéne Albert
Dubois, residing at Paris, in the Republic of France, upon the
condition (amongst others) that I, the said Edward Primerose
Howard Vaughan, 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. Edward Primerose Howard
Vaughan, 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 thereof, reference
being had to the accompanying Drawings, and to the figures and
letters marked thereon, that is to say :-
This Invention has for its object the extraction of gas for lighting and
heating from the liquid hydrocarbon known as "gasoline," by means of
improved apparatus, as shewn by the accompanying Drawings, in which
Figures 1, 2, are end views of the apparatus; Figure 3 is a front view of
the same; Figure 4, a horizontal section; Figure 5, a cross section; and
Figure 6, a top view. In all these Figures similar parts are indicated by
the same letters of reference.
A, A.,crepresent a cast-iron cylinder divided into two equal spaces or
compartments by the central partition B, in copper or brass, and closed
by the plates C, C, secured by the bolts D, D. In the axis of this
cylinder is mounted a hollow wrought-iron shaft E revolving in the
bearings F, G; H is a spiral shell or volute of sheet copper or brass, set,

page_text: on the shaft E, in the compartment A of the cylinder, and on the other
half of the shaft in the compartment A¹ is set a hair cloth drum J
.covered with a porous fabric, such as linen; K is a funnel by which the
·cylinder A, A¹, is charged with gasoline up to the level L, L; M is a
passage formed in the partition B; N, a glass gauge; O is a pulley
mounted on the prolongation of the shaft E, and driven by the band O¹
from the second pulley Q set on the shaft of the wooden roller P. On this
roller is wound the cord p, the free end of which passed through the blocks
R carries the driving weight S. The upper part T of the cylinder A, A¹, is
filled with air which, in the working of the apparatus is forced through
the spiral canals of the volute H, and thence by the hollow shaft E
through the saturated porous material J, and thus converted into
inflammable gas passes through the outlet pipe V to be distributed as
may be required; W, X, are regulators; Y is a purge cock.

The form, dimensions, and general details of construction of the
apparatus may be modified according to circumstances.
Having now described and ascertained the nature of the said Invention,
and the manner of carrying the same into effect, I declare that what I
claim and desire to protect by Letters Patent is, the manufacture of gas
for lighting and heating from the liquid hydrocarbon, known as
,"gasoline," by means of apparatus constructed and arranged substantially
as hercin set forth and shewn in the Figures of the accompanying
Drawings.
In witness whereof, I, the said Edward Primerose Howard Vaughan,
have hereto set my hand and seal, this Nineteenth day of 1
