IMPROVING AND INTENSIFYING THE LIGHT OF HORIZONTAL GAS BURNERS, AND FURNISHING THE SAME WITH GLOBES
Year: 1864

page_text: LETTERS PATENT to Andrew Steinmetz, Barrister-at-Law, Leicester,
Leicestershire, for the Invention of "IMPROVING AND INTENSIFYING THE
LIGHT OF HORIZONTAL GAS BURNERS, AND FURNISHING THE SAME WITH
GLOBES,"
Sealed the 26th July 1864, and dated the 15th February 1864.
PROVISIONAL SPECIFICATION left by the said Andrew Steinmetz at the
Office of the Commissioners of Patents, with his Petition, on the
15th February 1864.
I, ANDREW STEINMETZ, Barrister-at-Law, Leicester, Leicestershire, do hereby
declare the nature of the said Invention for "IMPROVING AND INTENSIFYING
THE LIGHT OF HORIZONTAL GAS BURNERS, AND FURNISHING THE SAME WITH GLOBES,"
to be as follows:-
I make the said globe of any shape, but it is entire at the bottom, and is
attached by its side to the fixings, thereby not only intensifying and improving
the light, but also doing away with the objectionable shadow of all other
appliances hitherto in use. The essential peculiarity of the globe consists in
its being entire at the bottom, where it is usually open, and being fixed at the
side where it is open. The burner to which my globe is adapted is the
common jet, fish-tail, or bat's-wing; but instead of fixing the jet vertically,
as usual, which is the most wasteful mode of using gas, I fix it horizontally,
furnishing the stem or support with an independent gallery attached screw-
wise, so as to adjust the gallery to the proper distance from the mouth of the

page_text: burner, that is to say, about three-quarters of an inch. The gallery to support
the globe has only two arms, but instead of the usual screw to fasten the
globe, which often causes breakage, I use a curved flange and screw, the
flange being moveable on a pivot, so as always to remain horizontal whilst the
screw turns, and clasping the globe securely without the danger of breakage
from tight screwing. The stem or support of the burner in the gallery is
elongated so as to bring the flame below the centre of the globe at any
distance from the centre compatible with safety to the globe; for the nearer
the flame to the glass the better the light; and to secure this result the globe
also should be made so as to get the larger part of it above the centre.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Andrew Steinmetz in the Great Seal Patent Office on the
5th August 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ANDREW
STEINMETZ, Barrister-at-Law, Leicester, Leicestershire, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of February, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the.
said Andrew. Steinmetz, Her special licence that I, the said Andrew Steinmetz,
my executors, administrators, and assigns, or such others as I, the said Andrew
Steinmetz, 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 Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVING AND INTENSIFYING THE
LIGHT OF HORIZONTAL GAS BURNERS, AND. FURNISHING THE SAME WITH GLOBES,"
upon the condition (amongst others) that I, the said Andrew Steinmetz, 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 per-
formed, 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 Andrew Steinmetz, do hereby declare the

page_text: formed; to be particularly described and ascertained in and by the following
statement:-
Instead of globes of the usual kind which cannot be used for horizontal
burners, that is to say, when the flame is delivered horizontally instead of
being vertical or upright, as usual, I make my globe entire at the bottom, the
opening and flange for fixing it being at the side, at right angles with the
usual opening at the top, thereby producing a shadowless light. The burner
to which my globe is adapted for producing this shadowless globe light is the
common jet, fish-tail, or bat's-wing; but instead of fixing the jet vertically,
as usual, which is the most wasteful mode of using gas, I fix it horizontally,
furnishing the stem or support with an independent gallery, attached screw-
wise, or sliding with a binding screw, to adjust the gallery to the proper
distance from the mouth of the burner. Instead of the usual screw to fasten
the globe, which often causes breakage, I use a curved flange and screw, the
flange being moveable on a pivot, so as always to remain horizontal whilst the
screw turns, and clasping the globe securely without danger of breakage from
tight screwing. The stem or support of the gallery and burner is elongated
so as to bring the flame below the centre of the globe, that is to say, at any
distance from the centre compatible with safety to the globe; for the nearer
the flame to the glass the better the light; and to secure this result the globe
should also be made so as to get a larger part of it above the centre. A wire
gauze is fixed to the stem or support of the burner, filling the side opening of
the globe, to regulate the current of air passing to the flame.
In witness whereof, I, the said Andrew Steinmetz, have hereu
my hand and seal, this Fifth day of August, in the year of ou
