IMPROVEMENTS IN BURNER APPARATUS FOR GAS FIRES
Year: 1884

page_text: I WILLIAM BELL of St Philips Road Sheffield in the County of York Gas
Fitter, do hereby declare the nature of my Invention for "IMPROVEMENTS IN
BURNER APPARATUS FOR GAS FIRES" to be as follows:-
My Invention relates to improvements in burner apparatus for gas fires, and
more particularly to the construction and arrangement of the burners, the object
being to increase the efficiency of such apparatus and to avoid some of the defects
and objections to which ordinary gas fires are subject.
In carrying out my Invention in the construction of such an apparatus, for
placing into an ordinary house fire grate for example, I shape a piece of sheet iron
or other metal, to fit and rest upon the bottom grate of the fire place; and I cut
out of or cast therein a series of apertures or gaps in the front edge of the plate
to receive the mouthpieces of the burners-On the underside and towards the back
of the plate I fix a receiver, or inlet pipe, preferably curved to correspond with the
front edge of the plate, and provided with a suitable connection to which the
supply pipe is attached Nipples or burners of a suitable size, are screwed into
the receiver or inlet pipe, and project in a line with the centre of each gap or
aperture. A metallic air tube is fixed in front of, and covers the end of each
nipple, leaving sufficient space round it for the admission of the requisite
proportion of air.
The mouthpiece of the burner proper, is of smaller area than the air tube, and is
curved upwards and projects above the metal plate, the mouth itself being cut off
diagonally, and sloping from the front. The opening I prefer to be square or
oblong. It will thus be seen that the mouths of the burners are at the front edge
of the fire, the flames being projected backwards upon and against the asbestos,
which is built up on a grid fixed on the top of the plate.

I, WILLIAM BELL of St Philips Road, Sheffield, in the County of York Gas
Fitter do hereby declare the nature of my Invention for IMPROVEMENTS IN
BURNER APPARATUS FOR GAS FIRES, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement, that is to say:-
My Invention relates to improvements in the construction of burner apparatus
for gas fires, and more particularly to the construction and arrangement of the
burners of such apparatus; the object being to produce a good and effective fire,
and to reduce to consumption of gas.
In describing my Invention as carried out in the construction of a burner
apparatus to be applied to an ordinary fire place, (for example) and in order that it
may be clearly understood, I shall refer to the accompanying Sheet of Drawings
and to the letters and figures marked thereon.
The same letters of reference indicate the same parts in all the Figures.
Fig. 1. is a top view of a burner apparatus constructed according to my Invention.
Fig. 2. shows the underside of same.
Fig. 3. shows a section of the apparatus.
A is a metal plate, to which the burners and other parts of the apparatus are
attached, it is made to conform to the shape of the fireplace, the front edge being
provided with gaps, B, to receive the burners C.
Upon the top of A I fix a number of supports D, and a rail E, on which is placed
the bed plate F; these parts carry the asbestos, or other substance of which the
body of the fire is composed.
Under the plate, I fix a gas receiver or inlet pipe, G, the connection to the supply
pipe, being made at any suitable part, such as at H. Gas nipples I, are fixed in
the front side, projecting horizontally towards the gaps B.
The burners C, are made from metallic tubing, curved upwards at the mouth, so
as to project above the plate A, and cut off obliquely, so as to direct the flame
backwards upon the asbestos.
Each burner is held in position by a staple K, and extends backwards so as to
receive the end of the nipple, sufficient space being left round the nipple, to admit
the requisite proportion of atmospheric air. Adjustable legs L, are of advantage
in raising the front of the apparatus to a suitable position.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
1. The construction of the burner apparatus of gas fires, consisting of the plate A,
the horizontal burners C, with the bedplate F, and supports D, substantially
as herein described and illustrated.
2. In gas fires, the use of a tubular burner (C) placed horizontally, having the
end curved and the mouth cut off obliquely, as hereinbefore described and
illustrated.
