Year: 1867

page_text: LETTERS PATENT to George Henry James Simmons, of 41, Stanhope
Street, Hampstead Road, London, Middlesex, Clerk, for the Invention
PROVISIONAL SPECIFICATION left by the said George Henry James
Simmons at the Office of the Commissioners of Patents, with his
Petition, on the 26th September 1867.
I, GEORGE HENRY JAMES SIMMONS, of 41, Stanhope Street, Hampstead
Road, London, Middlesex, Clerk, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN LAMPS FOR BURNING HYDROCARBON AND OTHER
OILS," to be as follows:-
Firstly. To the receptacle for the oil being away from the burner. For this
purpose for lamps with one burner I employ two tubes of different sizes, a
smaller tube enclosed in a larger tube, the ends of such tubes being soldered,
screwed, or otherwise fastened to the receptacle for the oil, and to a small
chamber, attached to which is the burner; the smaller tube is longer than the
larger tube on the end that is fastened to the receptacle for the oil, to allow

page_text: of the atmosphere to escape while it is being supplied with oil, the ends of the
tubes attached to the small chamber are nearly level with each other, con-
sequently the oil flows from the receptacle through the larger tube, until it
covers the opening of the smaller tube enclosed within it, preventing admittance
of the atmosphere to the receptacle, and more oil flowing into the small
chamber before mentioned than is required to supply the burner.
Secondly. The improvements relate to lamps with more than one burner.
Attached by means of a screw to the receptacle containing the oil are two
tubes parallel to each other; the tubes are furnished with a stop-cock or piece
of metal to slide over their opening, and enable the receptacle to be moved
without the oil spilling, the ends of the tubes not attached to the receptacle
are unequal in length, and are inserted into a small chamber; the effect of
which is the oil flowing from the receptacle down the longer tube rises in the
small chamber until it reaches the opening of the shorter tube, and by
preventing admittance of the atmosphere to the receptacle containing the
oil keeps the oil at one level. Attached to the said chamber are pipes
communicating to other small chambers, the bottoms of which are lined with
wire gauze, and to which are attached the burners.
The improvements also relate to the lamp first mentioned, the receptacle of
which is flat on one side, and to the top of such flat side is attached a metal
loop to permit of its being hung against a wall, and at bottom of such flat
side is hinged a piece of wire or metal to admit of its being placed upon a
table or other flat surface and remaining upright.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed'
by the said George Henry James Simmons in the Great Seal Patent
Office on the 9th March 1868:
TO ALL TO WHOM THESE FRESENTS SHALL COME, I, GEORGE
HENRY JAMES SIMMONS, of 41, Stanhope Street, Hampstead Road, London,

Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said George Henry James Simmons, Her special licence that I, the
said George Henry James Simmons, my executors, administrators, and
assigns, or such others as I, the said George Henry James Simmons, my

page_text: 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 LAMPS FOR
BURNING HYDROCARBON AND OTHER OILS," upon the, condition (amongst others)
that I, the said George Henry James Simmons, executors or adminis-
trators, 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 George Henry James: Simmons, 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 :-
The improvements in lamps for burning hydrocarbon and other oils relate, -
Firstly. To the receptacle for the oil being away from the burner. For this
purpose for lamps with one burner I employ two tubes of different sizes, a
smaller tube enclosed in a larger tube, the ends of such tubes being soldered,
screwed, or otherwise fastened to the receptacle for the oil, and to a small
chamber attached to which is the burner; the smaller tube is longer than the
larger tube on the end that is fastened to the receptacle for the oil, to allow of
the atmosphere to escape while it is being supplied with oil, the ends of the
tube attached to the small chamber are nearly level with each other,
consequently the oil flows from the receptacle through the larger tube until it
covers the opening of the smaller tube enclosed within it, preventing admittance
of the atmosphere to the receptacle and more oil flowing into the small
chamber before mentioned than is required to supply the burner.
Secondly. The improvements relate to lamps with more than one burner.
attached by means of a screw to the receptacle containing the oil are two tubes
parralel to each other, the tubes are furnished with stop-cock or piece of metal
to slide over their opening and enable the receptacle to be moved without the
oil spilling, the ends of the tubes not attached to the receptacle are unequal in
length, and are inserted into a small chamber, the effect of which is the oil
flowing from the receptacle down the longer tube rises in the small chamber
until it reaches the opening of the shorter tube, and by preventing admittance
of the atmosphere to the receptacle containing the oil, keeps the oil at one
level. Attached to the said chamber are pipes communicating to other small

page_text: chambers, the bottoms of which are lined with wire gauze, and to which are
attached the burners.
The improvements also relate to the lamp first mentioned, the receptacle of
which is flat on one side, and to the top of such flat side is attached a metal
loop to permit of its being hung against a wall, and at bottom of such flat side
is hinged a piece of wire or metal to admit of its being placed upon a table
or other flat surface and remaining upright:
In witness whereof, I, the said George Henry James Simmons, have
hereunto set my hand and seal, this Ninth day of March, in the year
of our Lord One thousand eight hundred and sixty-eight.
GEORGE HENRY JAMES SIMMONS. (L.8.)
