IMPROVEMENTS IN GAS BURNERS FOR INCREASING THE ILLUMINATING POWER OF GAS
Year: 1879

page_text: LETTERS PATENT to Frederick James Harrison, of 171, Queen Victoria Street,
in the City of London, for the Invention of "IMPROVEMENTS IN GAS BURNERS
FOR INCREASING THE ILLUMINATING POWER OF GAS."
Sealed the 6th January 1880, and dated the 7th July 1879.
PROVISIONAL SPECIFICATION left by the said Frederick James Harrison at
the Office of the Commissioners of Patents on the 7th July 1879.
FREDERICK JAMES HARRISON, of 171, Queen Victoria Street, in the City of
London.
"IMPROVEMENTS IN GAS BURNERS FOR INCREASING THE ILLUMINATING
POWER OF GAS."
This Invention has for its object the increase in the illuminating power of gas by
means hereinafter explained.
I screw into a boss of metal having holes to communicate the supply of gas 2 or
more fish tail burners parallel to and nearly touching each other, the holes in the
burners being so placed as to be in a line with each other. Between the two burners,
and projecting above them about a quarter of an inch at right angles to the holes, I
place a plate of metal or other incombustible material, which has the effect of
drawing the two lights together so that they burn with one flame of great brilliancy
and steadiness, and have a much increased illuminating power with a minimum
consumption of gas.
The plate placed between the burners may be of any size or shape, and may be
applied to existing burners where two or more fish tail or batswing burners are used,
or to the batswing burner with two slits.
f
The size of the light required will govern the number of the burner to be used,
but two No. 1 burners will, with the addition of the plate, give a light equal to an
ordinary No. 8 fish tail.
More plates than one may be used both outside the lights and inside; the plates
may also be straight or bent either towards or from the flame, as different shapes
or sizes of flame are required.

FREDERICK JAMES HARRISON, of 171, Queen Victoria Street, in the City of
-London"-IMPROVEMENTS IN GAS-BURNERS FOR INCREASING-THE ILLUMINATING
POWER OF GAS."
This Invention has for its object the increase in the illuminating power_of gas.by
means hereinafter explained.
I screw into a boss of metal having holes to communicate the supply of gas to
two or more fish tail or other burners parallel to and nearly touching each other,
the holes in the fish tail burners being so placed as to be in a line with each other,
and in the batswing burners parallel with each other. Between the two burners
and projecting above them I place a plate of metal or other incombustible material,
which has the effect of drawing the two lights together, so that they burn with one
flame of great brilliancy and steadiness, and have a much increased illuminating
power, with a minimum consumption of gas.
For sun lights I arrange on a circle in the ordinary manner a series of the double
burners above described, and either above or below, or both above and below them,
I place other burners at an angle, so that the gas escaping from them shall impinge
upon the flame given by the double burners. The same arrangement I apply to
upright jets for street and other illumination.
The plate placed between the burners may be of any size or shape, and may be
applied to existing burners where two or more fishtail or batswing burners are
used, or to the batswing burner with two slits.
The size of the light required will govern the number of the burner to be
used, but 2 No. 1 burners will, with the addition of the plate, give a light equal
to an ordinary No. 8 fishtail.
More plates than one may be used both outside the lights and inside; the plates
may also be straight or bent, either towards or from the flame, as different shapes
or sizes of the flame are required.
I claim, first, the plate or diaphragm between the burners; second, the arrange-
ment of sun, burners or lights hereinbefore described.
In witness whereof, I, the said Frederick James Harrison, have hereunto set
my hand and seal, this Seventh day of January, in the year of our Lord
One thousand eight hundred and eighty.
F. J.. HARRISON. (L.S.)
