AN IMPROVED GAS BURNER
Year: 1865

page_text: LETTERS PATENT to George Bray, of Leeds, in the County of York
Clothier, for the Invention of "AN IMPROVED GAS BURNER."
Sealed the 17th November 1865, and dated the 25th May 1865.
PROVISIONAL SPECIFICATION left by the said George Bray at the
Office of the Commissioners of Patents, with his Petition, on the 25th
May 1865.
I. GEORGE BRAY, of Leeds, in the County of York, Clothier, do hereby
5 declare the nature of the said Invention for "AN IMPROVED GAS BURNER," to be
as follows:-
My Invention has for its object the production of a greater illuminating
power from a given quantity of ordinary coal or other illuminating gas than is
now obtained by ordinary burners from the same quantity. I effect this by
the use of double-headed burners, such burners being placed, say, by preference,
at an angle of 30° to each other, and also near enough to each other to allow
the respective jets of flame to impinge upon and mingle with each other.
More than two burners may be used if desired, similarly placed to each other,
but I believe two to be most generally useful. The class of burner I prefer
to use is that technically known as the "bat's wing," burner though of course
others are applicable.
By the above-named arrangement I obtain a superior light from the same
consumption ofgas. Two or more jets of flames so impinging upon each other
the gas
is more thoroughly consumed.

statement thereof, that is to say :-
My Invention has for its object the production of a greater illuminating
power from a given quantity of ordinary coal or other illuminating gas than is
How obtained by ordinary burners from the same quantity. I effect this by
the use of double-headed burners, or burners so made as to emit two jets or
sheets of flame, by preference at an angle of 30° to each other, and also near
enough to each other to allow the respective jets or sheets of flame to impinge
upon and mingle with each other. More than two jets or sheets of flame may
be used if desired, similarly placed to each other, but I believe two to be most
generally useful. The class of jet or sheet 1 prefer to use is that produced
by what is technically known as the "bat wing" burner, though of course
others are applicable.

Having now described my Invention, what I claim is, a gas burner in
which two or more jets or sheets of flame are caused to impinge upon each
other and thus form one flame.
In witness whereof, I, the said George Bray, have hercunto set my hand
and seal, this Twenty-fourth day of November, in the year of our Lord
One thousand eight hundred and sixty-five.
