Improved Apparatus and Means for Burning Gas for Cooking and
Heating Purposes.
I QUIMBY SILAS BACKUS of 1734 North 15th Street, Philadelphia, State of
Pennsylvania, United States of America, Engineer, do hereby declare the nature of
my said invention to be as follows
--
This invention relates to a novel construction of atmospheric burner with air and
gas mixing chambers, in which chambers a regular distribution or spread of the
mixture takes place, so that all the outlets for combustion are equally supplied,
consequently all the flames are of the same height, with uniformity of colour, and
produces perfect combustion with great heat. In connection with my double
chambered apparatus I use a water trough, acting also as a stand, the front having a
loose fitting flap with a clearance behind so that vapour arising from the water may
be directed to the flames or jets, the usual unpleasant smell being suppressed thereby.
For the purpose of iny invention I cast or otherwise construct a double barrelled
burner apparatus, one barrel is of the full length to suit the stove or frame in or to
which the burner may be arranged; said barrel being closed at both ends and
provided with jet holes in an upper rib. The second barrel is formed by a bulge or it
is connected to the first named barrel in any desired manner, at about its central under
part and its opposite end has the usual air supply apertures, across the path of which
the gas jet passes like that of an injector.
The gas and air mixes in this lower barrel and the mixture has to travel into the
first named barrel by a bend or elbow like passage. It is so to speak checked in its
How which tends to equalize the pressure in the upper barrel, this serving as a
eservoir or governor and effects a regular supply to all the burner holes in the
op rib.
The burner apparatus is so made, that its ends rest in forks of a trough and as the
vater therein is vapourizing, or evaporating, the particles are directed by a loose
itting flap or plate to the flames for combustion.

page_text: The loose fitting flap or plate may have any degree of ornamentation upon it, either
as a casting or affixed to it.
This atmospheric burner apparatus is specially adapted for the domestic stoves
covered by my provisional specification No. 10281 of the present year, but, it is
applicable to all stoves, domestic or other, and to most cooking or heating apparatus
and by modifying its shape, such as a circular, a grid-iron, or other form it can be
made to suit the construction or arrangement of existing cooking or heating stoves.

COMPLETE SPECIFICATION.
Improved Apparatus and Means for Burning Gas for Cooking and
Heating Purposes.
I, QUIMBY SILAS BACKUS, of 1734 North 15th Street, Philadelphia, State of
Pennsylvania, United States of America, Engineer do hereby declare the nature
of this invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
This invention relates to a novel construction of atmospheric burner with air and
gas mixing chambers in which chambers regular obstruction or spread of the mixture
takes place so that all the outlets for combustion are equally supplied, consequently all
the flames are of the same height with uniformity of colour and produces perfect
combustion with great heat. In connection with my double chambered apparatus I
preferably use a water trough acting also as a stand, the front having a loose fitting
flap with a clearance behind, so that vapour arising from the water may be directed to
the flames or jets, the usual unpleasant smell being suppressed thereby.
For the purpose of my invention which is clearly shown in the annexed drawings I
cast or otherwise construct a double barrelled burner apparatus A, B, Figures 1 and 2,
one barrel B is of the full length to suit the stove or frame, in or to which, the burner
may be arranged, said barrel B being closed at both ends, and provided with jet
holes C in an upper rib. The second barrel A is formed by a bulge D, or it is
connected to the upper barrel B in any desired manner at about its central under part
and its opposite end has the usual air supply apertures E, across the path of which,
the gas jet from the nozzle F, see Figure 3, passes like that of an injector.
The gas and air mix in this lower barrel A and the mixture has to travel into the
upper barrel B by a bend or elbow like passage D and is, so to speak, checked in its

page_text: flow which tends to equalize the pressure in the upper barrel B, this serving as a
reservoir or governor and effects a regular supply to all the burner holes C in the
top rib G.
The burner apparatus is provided with shoulders H, 1, (see Figures 1 and 4) and is
so made that it can rest between forks J of a trough K and as the water therein is
vapourizing or evaporating, the particles are directed by a loose fitting flap or
plate L, see Figure 5, to the jets of flame for combustion. The loose fitting flap or
plate L may have any degree of ornamentation upon it, either as a casting or
affixed to it.
Figure 6 is a transverse section of the barrel A, B, Figure 2.
This atmospheric burner apparatus is specially adapted for the domestic stoves
covered by my previous Specification Patent No. 10281 of the present year, but it is
applicable to all stoves, domestic or other and to most cooking or heating apparatus
and by modifying its shape, such as a circular, as indicated at Figures
and S, a
gridiron, Figure 9, or other form, it can be made to suit the construction or
arrangement of existing cooking or heating stoves.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The two chambered apparatus as an atmospheric burner for heating purposes by
mixture of gas and air, the construction being that shown in the annexed drawings
Figures 1, 2, 4, 6, 7, 8, and 9, in or by which the combination of two barrels, a
thorough mixing of gas and air takes place in the lower barrel A, the upper barrel B
serving to govern the exit of the mixture from apertures in the rib G as set forth.
2. In combination with a double chambered burner as above set forth the water
trough K and loose fitting plate L for directing the vapour to the gas flame as and
for the purpose described with reference to Figures 3 and 5 of the annexed drawings.
Dated the 1st December 1887.
