Office of the Commissioners of Patents on the 7th August 1879.
ALBERT MARCIUS SILBER, of No. 49, Whitecross Street, in the City of London.
IMPROVEMENTS IN GAS BURNERS."
My Invention relates to the construction of gas burners, in which two burners
that produce flat flames, such as the batswing or fish tail burners, are placed side
by side with a space intervening, and in such positions that the flat flames issuing
therefrom meet together at their upper parts. My improvements consist in the
application to such burners of means whereby the air supply is directed in a more
effectual manner between and against the flames so as to produce a more vivid light
therefrom than has been done heretofore. For this purpose, according to one
arrangement, I fit between the two burners a partition (which in some cases may
be wedge-shaped) reaching up to a short distance above the tops of the burners and
extending some distance on each side thereof, so that the air in passing up against
the sides of the said partition is directed upwards thereby in two separate con-
verging currents, which are brought gradually in contact with the inner surfaces of
the two flames without effecting any disturbance thereof. According to another
arrangement I provide in place of or in conjunction with the said partition, a rim,
ring, or band (which in some cases may be circular) surrounding the two burners,
the upper edge of which rim may be slightly curved outwards, so that the air in
passing over it to the burners is directed in a downward curve to the space between
the two flames, between which it then rises.

DESCRIPTION OF THE DRAWINGS.
space
between
Fig. 1 is a side view and Fig. 1a a plan of a duplex burner consisting of two flat
flame burners A. A, placed side by side upon one supply pipe. For such a burner
I provide a partition B, somewhat wedge shaped and situated midway between the
burners. Fig. 2 is a side view and Fig. 2a a plan of a triplex burner having three
flat flame burners A, A, A, placed side by side. In this case I provide two
partitions B, B, one between each pair of the contiguous burners; and in like
manner, as may be readily understood, for multiple burners giving four, five, or
more flames, I provide between each contiguous pair a partition, such as B, which
has the effect of arresting cross currents of air and directing them upwards along
with the flames. Instead of placing the partitions as shields between the burners,
as shewn in Figs 1, 14, 2, and 2a, or in addition to these a protecting rim may enclose
the burners, as shown in the part section, Fig. 3, and plan, Fig. 3, of a duplex
burner. In this case the protecting rim is made as a ring C, surrounding the
burners and made to project a little outwards at its upper edge, so as to arrest cross
currents and give them the desired direction.
Having thus described the nature of my said Invention and in what manner the
same is to be performed, I claim,―
First. The use, in combination with a multiple gas burner, of one or more
partitions B between the contiguous burners, substantially as herein described with
reference to Figs 1, 1ª, 2, and 2ª of the accompanying Drawings.
Second. The use, in combination with a multiple gas burner, of a protecting rim
surrounding the burners, substantially as herein described with reference to Figs. 3
and 3ª of the accompanying Drawings.
In witness whereof, I, the said Albert Marcius Silber, have hereunto set my
hand and seal, this Twenty third day of January, in the year of our
Lord One thousand eight hundred and eighty.
