1, WILLIAM MOFFATT of Millfield Terrace, Hexham, in the County of Northumber-
land, Ironmonger, do hereby declare the nature of this invention to be as follows:-
My invention which relates to apparatus for heating and cooking by gas consists
(1) of a double entrance" burner, that is to say, a burner having two inlets for the
admission of gas and air the burner itself being in the form of a ring or of other
suitable form provided with jets, and (2) in the application of such a burner in combi-
nation with a fret, grill or similar device for supporting cooking utensils and adapted
for attachment by hinging or otherwise to a cooking range to serve as an auxiliary
cooker.

Improvements in Apparatus for Heating and Cooking by Gas.
I, WILLIAM Moffatt of Millfield Terrace, Hexham, in the County of Northumber-
land, Ironmonger, 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 :-
My invention which relates to apparatus for heating and cooking by gas consists
(1) of a "double entrance" burner, that is to say, a burner having two inlets for the

page_text: admission of gas and air, the burner itself being in the form of a ring or of other
suitable form provided with jets, and (2) in the application of such a burner in combi-
nation with a fret, grill or similar device for supporting cooking utensils and adapted
for attachment by hinging or otherwise to a cooking range to serve as an auxiliary
cooker.
In the accompanying drawings which illustrate my invention figures 1, 2 & 3 are
elevations and figure 4 a longitudinal section of the combined gas burner and grill or
fret as fitted in connection with a cooking range. The grill or fret A, may be of
any well known form and is hinged or pivotted at a to the end or back of a cooking
range over the hot plate B, so that it may be tilted up in the position shown by full
lines in figures 1, 2 and 3 to be clear of the hot plate B, or brought down to the
position indicated by dotted lines in these figures and in full lines in figure 4 as resting
on the hot plate to support culinary-utensils which are placed on it and are heated by
gas jets issuing from the burner C, which is attached to or may form part of the frot
or grill. The burner is composed of a tube the greater part of whose length forms a
ring and whose ends in which are the air and gas inlets are brought parallel to each
other and have fitted into them small nozzles d discharging gas into the burners from
a gas tube D, provided with a tap d', and extending along the edge of the grill or
fret to the axis upon which the grill is pivotted or hinged and where it is formed with
a swivel joint DI, serving as one of the pivots, the gas tube being thence carried
along the end of the range and connected to any convenient supply pipe. On the
under side of the burner C, and immediately under the nozzles d, orifices c are cut in
the burner tube to admit air, the gas and air passing together into the tubular ring
and issuing at jet orifices c¹ where combustion takes place.
The burner which may be of oval, oblong or other form instead of being circular
acts as a Bunsen burner but differs therefrom in having gas and air inlets at each end
of the tube constituting the burner whilst combustion of the gas takes place at a series
of dischargo jets throughout its length.
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. A combined gas burner and grill or fret constructed and fitted, substantially as
described with reference to the annexed drawings.
2. A "double entrance" gas burner, for heating and cooking purposes, constructed
substantially as herein described with reference to the annexed drawings.
