PROVISIONAL SPECIFICATION.
Improvements in Gas Burners for Heating and Cooking.
We, SAMUEL CLARK and FRED HATCHER, Stove Manufacturers, of Syphon
Works, and EDWIN CHALLIS, Mechanic, of 25 Sebbon Street, all of Park Street,
Islington, in the County of Middlesex, do hereby declare the nature of this inven-
tion to be as follows:-
The invention is applicable to that class of heating and cooking burners con-
sisting of a Bunsen burner tube, the gas and air from which pass through a long
slot in each side thereof into a flat chamber having a number of holes in the top,
each of which is provided with a short tube, and the gas and air are burnt at the
tops of these said tubes.
The object of the present invention is to obtain more perfect combustion, to
increase the heat, and to produce a more steady flame.
In carrying our invention into effect we take an ordinary Bunsen burner tube
having two long slots in each side for the escape of the mixed air and gas into a
flat chamber as above described. In the top of the said flat chamber we form a
number of holes provided with short tubes similar to those already in use and above
described. In the bottom of the said flat chamber are a corresponding number
of holes opening into tubes passing up centrally through the above mentioned short
tubes. The mixed air and gas passes up between the two tubes and is burnt at the
top thereof. The inner tubes supply pure air to the centre of the flames and will
thus greatly increase the heat and cause them to burn more steadily and obtain
more perfect combustion.
The burner may be made of sheet metal or it may be made up of castings.

Improvements in Gas Burners for Heating and Cooking.
We, SAMUEL CLARK and FRED HATCHER, Stove Manufacturers, of Syphon
Works, Park Street, and EDWIN CHALLIB, Mechanic, of 25 Sebbon Street, all of
Islington, in the County of Middlesex, do hereby declare the nature of this inven-
tion, and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement, reference being had to the
accompanying drawings and to the figures and letters marked thereon:-
The invention is applicable to that class of heating and cooking burners con-
sisting of a Bunsen burner tube the mixed gas and air from which pass into a flat
chamber having a number of holes in the top, each of which is provided with a
short tube, the gas and air being burnt at the tops of these said tubes.
The object of the present invention is to obtain more perfect combustion, to
increase the heat, and to produce a more steady flame.
Figure 1 is a plan, and Figure 2 is a longitudinal section, of a burner suitable for
heating baths and for other purposes.
Figure 3 is a plan representing the invention applied to a portable stove to
receive on the top thereof a kettle or other utensil, and Figures 4 and 5 are

page_text: respectively a plan and vertical section representing the invention applied to a
burner suitable for heating urns and for other purposes.
In all the figures like parts ure indicated by similar letters of reference.
In carrying our invention into effect, according to the examples represented at
Figures 1, 2 and 3, we use an ordinary Bunsen burner tube a having a long slot a¹
in each side for the escape of the mixed air and gas into a flat chamber b, as is well
understood, or, according to the example represented at Figures 4 and 5, the end of
the Bunsen burner tube a may open directly into the centre of the chamber b, or
other suitable arrangement for conveying the mixture of gas and air into said
'chamber may be employed.
In the top of the flat chamber 6 we form a number of holes provided with
short tubes 63, similar to those already in use as above described. In the bottom b³
of the said flat chamber, we provide a corresponding number of holes opening
into tubes 6* fixed to such bottom plate and passing up centrally through the above
mentioned short tubes 6. The mixture of air aud gas passes up between the two
tubes and is burnt at the tops thereof. The inner tubes 6 supply pure air to
the centre of the flames and will thus greatly increase the heat and cause them to
burn more steadily and obtain more perfect combustion.
The body of the burner may be made of sheet metal or it may, together with the
burners, 'be made up of castings..
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim, is :-
1. In gas burners in which air and gas are introduced into a chamber the top of
which is provided with short burner tubes, the combination therewith of a perforated
bottom having tubes fixed in or connected to such perforations and passing up
centrally through the short burner tubes of the upper plate, for the purpose of
supplying pure air to the centre of each flame, substantially as herein shown and
described.
2. In gas burners for heating and cooking, the peculiar combination and arrange-
ment of parts whereby pure air is supplied to the centre of each flame, substantially
as herein described.
