Improvements in the Burners of Gas Cooking Apparatus.
I, HARRY JAMES YATES, of the firm of Arden Hill and Company, of Wharf
Road, Aston, near the City of Birmingham, Gas Engineer, do hereby declare the
nature of this invention to be as follows:-
This invention has reference both to the burners and to the cocks or gas-con-
trolling means of gas cooking apparatus, and employed principally in that type of
apparatus known as "grillers," in which a horizontal and longitudinal burner is
disposed between a pair of grill plates, hung or swung from their outer edges and
arranged to alternately rise above and fall below the gas jets of the said burners,
which are arranged in line and issue from the two opposite sides thereof so as
to play either upon the undersides of the plates for grilling, or be free to impinge
directly upon the bottom of a vessel placed upon the stove or griller for boiling,
heating or frying purposes.
The improved burner consists of a longitudinal tube or bar, having a partition
or diaphragm down its middle so as to make two side by side passages, which are
closed at one end and open at the other end, with gas jet holes provided in a line
along the two outer sides of the walls of the said burner, which is located between a
pair of grill plates swinging from their outer edges upon journals or equivalents,
and adapted, when in a grilling position to lie above the jet holes, so that gas jets
proceeding therefrom can play upon the undersides of the plates for grilling, but
when the grill plates are dropped, the jets impinge directly upon the underside of
a boiling, frying or like vessel placed upon the stove.
In addition to the advantage of each of the dual sets of jets being independently
supplied with gas, my improved burner admits of either one side or both sides of
the burner being used at the same time.
The open end of the burner is provided with two holes for taking over the gas-
supply nipples for supporting the said burner, which is a loose one, whilst the
other end has an extension which takes upon a rest or seating formed in the walls
of the stove or cooking apparatus. Air inlets are also arranged upon the opposite
sides of the said open ends.
This atmospheric gas burner is preferably rounded upon the crown and has
vertical sides, and the lower underside tapers inwards with the apex concave
grooved or channelled, so as to reduce the bulk of metal at that part and lessen
the normal depth of the burner.
Instead of the two chambers being entirely separated by the partition, an
opening may be left or formed in the partition at the closed end, so that one side
or compartment may be in communication with the other.
The means for controlling the supply of gas to the burner consists of a single
cock or tap divided by a plug with a single gas-way through it, the shank of the
said cock also having a single gas-way, whilst above the plug, the cock is boxed
and divided off into two compartments or passages respectively in communication
with the nipples taking into the openings in the burner end.

page_text: The gas way in the plug has sufficient lead as to admit of the same (when the
plug is in one position) over-lapping the central partition and thus being in com-
munication with both the passages above the plug at the same time, and according
as to the extent to which the plug is turned either to the left or the right, so
the supply of gas to the one passage is increased and proportionally diminished
to or fully cut-off from the other, whilst a further turning of the plug cuts off gas
altogether from both passages.

Improvements in the Burners of Gas Cooking Apparatus.
I, HARRY JAMES YATES, of the firm of Arden Hill and Company, of Wharf
Road, Aston, near the City of Birmingham, Gas Engineer, do hereby declare the 1
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:—
'This invention has reference both to the burners and to the cocks or gas-con-
trolling means of gas cooking apparatus, and employed principally in that type of
apparatus known as "grillers," in which a horizontal and longitudinal burner is 2
disposed between a pair of grill plates, hung or swung from their outer edges and
arranged alternately to be raised above and to fall below the gas jets which are
arranged in line and issue from the two opposite sides of the said burner, so as to
play either upon the undersides of the plates for grilling, or be free to impinge
directly upon the bottom of a vessel placed upon the stove or griller for boiling, 2
heating or frying purposes.
Figure 1 of the accompanying drawings represents a topside plan of a gas
cooking stove, the griller part of which is fitted or provided with a double burner
constructed according to my invention.
Figure 2 is a section thereof, upon the dotted line x, showing the said burner in a
side elevation.
Figure 3 is a transverse section of figure 1 upon the dotted line a¹, with the
griller plates raised, in which position the flame jets from the burner play against
the underside of the same, and figure 4 is a like view as figure 3, but with the said
plates lowered to allow the flames to play against the underside of a vessel placed
upon the stove.
Figure 5 is a topside plan of the burner, separately, and upon an enlarged scale.
Figure 6 is a transverse longitudinal section of the said burner, and figure 7 is
a side elevation of the same.
Figure 8 is an elevation of the closed end.
Figure 9 is a vertical section upon the dotted line ³, figure 7, and
Figure 10 represents an elevation of the opposite end of the burner, showing the
openings therein for taking over the nozzles of the gas cock.
Figure 11 is a like view as figure 9, but upon a further enlarged scale.
The same letters of reference indicate corresponding parts in the said figures 1
to 11.
The improved burner, as represented in the said figures, consists of a longi-
tudinal tube or bar a, having a partition or diaphragm a', down its middle which
divides the said tube interiorly up into two side-by-side passages a³, a³, forming as
it were, two separate or independent burners, both of which are closed at one end a*,

page_text: and the other end as, has holes as, which take over the nozzle of the gas supply
pipe or cock whilst gas jet holes a, provided in a line along the two outer sides a²,
of the walls of the tube. The said burner, which is located between a pair of grill
plates 61, swinging from their outer edges 60, upon journals or equivalents 620,
and adapted, when in a grilling position, to lie above the jet holes a, so that gas
jets proceeding therefrom can play upon the undersides of the plates for grilling,
but when the grill plates are dropped, the jets impinge directly upon the underside
of a boiling, frying or like vessel placed upon the stove.
In adition to the advantage of each of the dual sets of jets being independently
supplied with gas, my improved burner admits of being independently or collec
tively used.
The said burner is a loose one, one end a², may be supported by taking over the
nozzles 63, 61, whilst the other end al, may rest upon a bearer bar or seating c¹,
directed from side to side of the opening in the top frame d, of the stove or
cooking apparatus d. Air inlets all, are also arranged upon the opposite sides of
the said open ends.
The burner is also preferably rounded upon the crown a¹, and has vertical
sides a and the lower underside a¼, may be inclined or taper inwards with the
apex a¹5 concave grooved or channelled, so as to reduce the bulk of metal at that
part and lessen the normal depth of the burner.
Figure 12 represents an elevation of my improved cock or means for controlling
the supply of gas to double burners or to a single double-chambered burner such
as represented and described in connection with figures 1 to 11.
Figure 13 is a complete vertical section of the same.
Figure 14 is a vertical section of figure 12 upon the dotted line ³, showing the
passage through the plug in the same position as represented in figure 13, viz., fully
opened to supply gas to both chambers of the double burner.
Figure 15 is a like section as figure 14 but with the plug partially turned into
such a position as to cut off gas from the left hand chamber of the burner and
Figure 16 represents a like section, but with the plug in position for cutting off
gas from the right hand chamber, whilst when the gas way or passage through the
plug is in the position represented by the dotted lines in this figure, gas is cut off
entirely from both chambers.
This means for controlling the supply of gas to the burner may consist of a
single cock or tap b, divided by a plug 6, with a single gas-way b³, through it, the
shank of the said cock below the plug, also having a single gas-way b', whilst above
the plug, the cock is boxed and divided off into two compartments or passages 65, 6º,
respectively in communication with the nipples 62, taking into the openings or
holes a, in the end of a double chambered burner. The gas way b³, in the plug
has sufficient lead as to admit of the same (when the plug is in one position) over-
lapping the lower end of the central partition 67, in the box part of the tap, and
thus being in communication with both the passages 65, 66, above the plug at the
same time, and according as to the extent to which the plug is turned either to
the left or the right, so the supply of gas to the one passage is increased and pro-
portionally diminished to, or fully cut off from the other, whilst a further turning
of the plug into the position represented by the dotted lines in figure 10 cuts off
gas altogether from both passages.
Figure 17 represents a vertical section of a modification of this part of my
invention in which the plug 6', has a three branch way 63, which branches when
the tap is in the position represented for allowing the full supply of gas to pass
into both chambers of the burner, are respectively in communication with the
passages 65, 66, leading to the nozzles 610, and with the passage ba, in the shank.
Figure 18 represents a further modification in which 61, is the plug, 63 the three
branch way through the same, communicating respectively with the passages 65, 66,
to the nozzles 610 and the passage 62, in the shank.
By the employment of such cocks or gas controlling means, gas may be supplied
selectively, or as required, to either one or to both of the passages of a double

page_text: burner, or to two separate burners, or they may be arranged so as to admit of
small regulated quantities of gas being supplied to both burners or burner passages.
If necessary, by-passes may be provided in connection with such burners and gas
controlling means as herein described, for keeping a small jet constantly alight
adjacent to the flame-jet holes of the burner.
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 :-
First: A burner for gas-stoves for grilling and like purposes, consisting of a
hollow bar or tube, divided off interiorly into two longitudinal compartments, each
having separate gas and air inlets and flame jet holes, thus forming a double
burner.
Secondly: An atmospheric burner for gas stoves for grilling and like purposes,
consisting of a hollow bar or tube, divided off interiorly into two longitudinal
chambers or compartments, each chamber having an air inlet and a gas supply
inlet at or near one end, and a series of flame jet holes along one side, substantially
as described and set forth.
Thirdly-A cock or gas controlling means for use in connection with a double
burner or two burners, having a single inlet passage and double outlet passages
controlled by a single or three-way plug, arranged and constructed substantially as
described and set forth.
