Improvement in the Construction of Gas-burners for Cooking and
Heating Purposes.
SIGISMOND LEONI Gas Engineer at 114 Cannon Street and JAMES SINCLAIR Fire
Engineer also of 114 Cannon Street London Middlesex do hereby declare the nature
of this invention to be as follows:-
Whereas the boiling tables or hotplates forming the top part of gas kitcheners
or gas ranges are at present fitted with gas burners fixed in their respective places
by means of screws or other fastenings and are joined with the gas feeding pipes
in such way as to make the said burners a fixture, great difficulties are experienced
before any of the burners can be removed. Screwdrivers, gas plyers, and other
tools have to be used by experienced hands; this being troublesome & costly, the
cleaning of the burners is generally neglected the burners burn the gas badly and
much gas is wasted. The orifices of the burners from which the gas jets burn,
are constantly liable to become clogged or choked and to get filled in from the
dirt and mess caused by the overboiling of greasy or vegetable matter, and unless
such burners are freed from such impediments and obstructions they will become
altogether useless.
Now the object of our invention is to construct gas burners in such way as to
enable persons to remove them at any time without even the use of tools of any
kind, and our invention consists in forming iron or other metal supports, grates,
beds, seats, holes, pegs, or pins in which burners of various shape, may move,
ride, slide, and rest. The burners may be of tubular shape to move or rest inside
a groove, or of a square longitudinal form rather wide at the top but diminishing.
towards the base and therefore conical, which will move and rest in slots or slides,
or troughs. The burners may also be of a square, round, or oval shape, the bottom
of which is provided with pins, pegs or holes, to fit on to corresponding parts of
the grate seat, bed or basis. The gas inlet to any of these burners will meet the
outlet of the gas supply without it being necessary or desirable to make a joint or
a fixture. The burners being free and independent of all fittings, can be removed
in the manner described, by the least experienced person.
Our invention further consists in constructing straight longitudinal burners
provided with flanges or wings the whole forming one inseparable body; the wings
or flanges move or rest on supports or slides fixed from the top of the hotplate,
or table or grilling stove.
The wings extend from end to end the whole length of the burner, the wing of
one burner will meet the wing of the next burner, the two wings thus joining
will form a heat deflecting plate.
Immediately below these wings gas jets issue and form one continuous sheet of
flame from which the heat is radiated by means of the wing deflector on to the
meat, fish, or bread to be grilled broiled or toasted, just below the gas flame.
Due provision is made to promote combustion by providing sufficient openings
through the said wings.
The said burners resting on slides as described and being independent of the gas
inlet and all fittings or fixtures can be removed from the front of the griller or
hot-plate for the purpose of cleaning or renewal.
Dated this 27th day of Sentember 1889.

COMPLETE SPECIFICATION.
Improvement in the Construction of Gas-burners for Cooking and
Heating Purposes.
We SIGISMOND LEONI of No. 114 Cannon Street in the City of London Gas
Engineer and JAMES SINCLAIR of the same place Fire 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 :-
The object of our invention is to construct gas burners in such way as to enable
any person to remove the whole or either of them at any time without the use of tools
and our invention consists in forming iron or other metal supports of various shape on
which the burners rest and the whole or either of them may be placed or removed in
or out at any time as required. The burners may be of a round square longitudinal
tubular or flat shape or form or in any other shape or form as desired. The burners
are left free and independent of all fittings and fixtures and can be removed or replaced
at all times without difficulty. Our invention further consists in constructing separate
straight longitudinal burners provided with, flanges or wings the burner flanges or
wings forming one inseparable body; the flanges or wings rest or move on supports or
slides fixed underneath the hotplate of a kitchener or inside the top or roof of a grilling
stove.
The flanges or wings between two or several burners joining together form a heat
deflector above the gas jets which issue from the body of the burner immediately below
the wings; the heat generated therefrom is deflected and radiated from the surface of
the wings on to the meat fish or toast to be broiled or grilled below the burners,
openings are provided to ensure complete and perfect combustion.
The said burners being free and independent of any gas fittings and connections can
be removed whenever required without the use of tools.
In order that our invention may be fully understood we will proceed to describe it
more particularly by the aid of the accompanying drawings in which are represented
different views and parts of our improved burners.
DESCRIPTION OF THE DRAWINGS.

Figs. 4 & 5 represent the end views of the burner A. Figure 4 is open to the gas
inlet, Fig. 5 is the closed end of the burner A.

Fig. 17 represents the plan and end view of the grate or slide C in which the
burner A, with wings B. B. can be moved to and fro.

page_text: The following are some of the advantages resulting from the application of our
inventions.
First. The facility of removing the burners for the purpose of cleaning.
Second. The facility of replacing any damaged burner or carrier or support.
Third. The greater efficiency and consequent economy in the consumption of gas by
enabling the consumer to keep the burners clean and in constant good and regular
working order, and to use the same burners at one and the same time for grilling and
boiling or either.
Fourth. The grilling burner combining in its form of construction the necessary
deflector does away with the necessity of a separate deflector which requires more
room and more metal, also the extra labour of having to be moved in or out of its
place and therefore being more liable to go wrong and of being damaged.
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 :-
:-
First. The construction and application of supports, carriers, grates, seats in which
one or any number of burners can be made to slide in or out and to be removed at
will by any person without the use of a tool substantially in the manner as hereinbefore
described.
Second. The construction and application of a grilling burner with wings or
flanges all in one piece substantially in the manner as bereinbefore described.
Thirdly. The separate independent míovable supports carriers grates or seats to
carry one or an unlimited series of burners and the use of such burners so carried or
supported for either boiling or grilling or for both operations at the same time.
