Street in the County of Middlesex Gas Engineer for an Invention of
" IMPROVEMENTS IN BURNERS APPLICABLE TO GAS COOKING APPARATUS
"
PROVISIONAL SPECIFICATION left by the said Sigismund Leoni at the
Office of the Commissioners of Patents on the 29th May 1883.
SIGISMUND LEONI of 66 St Paul Street, Packington Street, in the County of
Middlesex Gas Engineer "IMPROVEMENTS IN
COOKING APPARATUS "
BURNERS APPLICABLE TO GAS
My Invention has for its object the construction of an atmospheric gas burner
for boiling and other cooking operations, which is easy of manufacture, readily
cleaned and at the same time effective for boiling and other cooking purposes.
And my invention consists in forming the burner by casting it in two parts (of
iron or other suitable material) one part being larger than the other, and the
larger portion is so made as to form with the smaller part a hollow chamber into
which the gas and air pass and issue through notches made in its edges to produce
the jets of burning gas. The smaller part acts a lid or cover to the larger or
main part of the burner and is fitted thereto without rivets or other fastenings.
The form of the burner may be varied; for instance, it may be annular or ring-
shaped in which case the notches to produce the gas jets will be formed round the
outer and inner sides or rings thereby causing jets of gas to issue both externally
and internally from the burner. Or if the burner be made in the form of a
parallelogramn the notches would be cast along each side.
The burner may be mounted to act as an ordinary gas ring for separate
cooking in the usual way or fitted under the hot plates of a kitchener or otherwise
as required

"
My Invention of 'Improvements in Burners applicable to Gas Cooking
Apparatus" has for its object the construction of an atmospheric gas burner for
boiling and other cooking operations which is easy of manufacture readily
cleaned and at the same time effective for boiling and other cooking purposes.
And my Invention consists in forming the burner by casting it in two parts
(of iron or other suitable material) one part being larger than the other and the
larger portion is so made as to form with the smaller part a hollow chamber into
which the gas and air pass and issue through notches made in its edges to produce
the jets of burning gas
The smaller part acts as a lid or cover to the larger or main part of the burner
and is fitted thereto without rivets or other fastenings.
The form of burner may be varied for instance it may be annular or ring-shaped
in which case the notches to produce the gas jets will be formed round the outer
and inner sides or rings thereby causing jets of gas to issue both externally and
internally from the burner. Or if the burner be made in the form of a parallelogram
the notches would be cast along each side.
The burner may be mounted to act as an ordinary gas ring for separate cooking
in the usual way or fitted under the hot plates of a kitchener or otherwise as
required.
Having thus stated the nature of the said Invention I will proceed to describe
more particularly the manner in which the same is to be performed by the aid of
the accompanying drawings in which are represented the parts of apparatus above
Fig 1 represents a plan or horizontal view of the ring or annular form of burner
with a portion of the cover removed.-Fig: 2 represents a longitudinal elevation
of the same Fig: 3 is a longitudinal section of Fig: 2; Fig: 4 is a plan or
horizontal view of a burner in the form of a parallelogram the cover being removed;
Fig 5 is a longitudinal section of this form of burner but with the cover also
shown in section.
In these several figures the same letters of reference indicate corresponding
parts.
A is the larger part or portion of the burner which with the smaller part B
forms a hollow chamber into which the gas and air pass and issue through notches C
made in its edges to produce the jets of burning gas.
The smaller part B acts as a lid or cover to the larger or main part A of the
burner and is fitted thereto without rivets or other fastenings but in some cases it
might be advisable to use one or several screws or other fastenings.
The form of the burner may be varied for instance it may be annular or ring-
shaped as shewn in Figures 1, 2, and 3 in which case the notches C to produce the
gas jets will be formed as shewn (Figures 1, 2, 3) round the outer and inner sides
or rings thereby causing jets of gas and air to issue both externally and internally
from the burner.

page_text: Or if the burner be made in the form of a parallelogram the notches C would be
cast along each side as shewn in Figures 4 and 5.
Having thus described the nature of the said Invention and in what manner the
same is to be performed I hereby declare that what I claim as of my Invention is:
The construction of an atmospheric gas burner which is easy of manufacture, the
parts of which are readily separated for the purpose of cleaning and which is
effective for cooking purposes all substantially as herein before described
In witness whereof I the said Sigismund Leoni have hereunto set my hand
and seal this twenty third day of November in the year of our Lord One
thousand eight hundred and eighty three.
