PROVISIONATI DI MOITIVATION,
Improvements in Gas Cooking Stoves.
I, HARRY JAMES YATES, of the Firm of Arden Hill and Company of
224 Lichfield Road, Aston, near the City of Birmingham, Gas Stove Manufacturer,
do hereby declare the nature of this invention to be as follows:-
This invention has relation to detail improvements in the bottom and top burners
of gas cooking stoves, and has for its object, to simplify the fitting or setting in
position of the same without the employment of any loose attachments.
Thus according to my improvements the said burners are made self fitting and
self supporting.
The bottom burners consist essentially of a tubular chamber with a supplementary
tubular air chamber, running parallel with the burner and entering the same n
short distance from its middle. The inner end of the burner has an axial hole
through it, wherein the jet of the gas delivery pipe enters with the nozzle coming
opposite a gap or air inlet, so that as the gas enters the chamber, it intermingles
with the gas prior to the same entering the burner, which has jet holes running
lignable along its inner side.
Directed along the middle of the back walls of the base of the stove is a
horizontal pipe, whose ends pass through the walls of the opposite sides and form
the termination to a vertical pipe passing from the cross pipe which feeds the top
burners.
This inwardly located pipe which supplies gas to the bottom burners, has at its
two opposite ends and within the boundary walls of the cooker, two projecting
nipples or open ended conical plugs, which fit into the holes in the back ends of the
air chambers of the burners, which are disposed vertically or edgewise and parallel
with and adjacent to the inside walls of the stove.
The front end of each of the burners is closed aud comes against a vertical stop
or web lying across a rest pocket formed integral with the stove, whilst coming
above and running in line with the burner is a shelf or outstanding flange, which
hides the burners from view, whilst the top and bottom sides of the burners arc
provided with flats or facets, or are made D sectioned at certain points so as to
form flat bearings which come upon outstanding rest flanges carried at any part of
the stove within the range of the burners, which are thereby prevented from shaking
or rocking loose.
Thus, each of the burners has a flat near the bend of the air chamber, which is
adapted to come upon a corresponding flat part of a rest bracket directed
horizontally inwards from the base, whilst the topside of the burner has a
corresponding flat or facet which comes and fits snugly under the shelf, thereby
keeping the fitted burner steady.
I wish it to be understood that I do not limit myself to the positions of the flats
and shelf rests, which may be located at any point most suitable, and further any
similar or equivalent device may be employed for steadying the burners. The
shapes of the pockets may be varied or made so as to accommodate like shaped
ends of the burners, which may fit therein without any liability to displacement.
The gas supply pipe may, if necessary, cross the front of the base of the stove.
In carrying out my invention in connection with top burners, I employ tubular
shaped air tubes, terminated by annular and jet pierced burners, and with the fore

page_text: part of each air tube or chamber side gapped to form an air inlet, and with a hole
in the said end which takes over a gas supply nozzle leading from the gas main.
The air chamber ends of the burners rest in holes formed through the top of the
stove, whilst the burners rest on outstanding brackets, each having a hole wherein
a stud on the underside of the burner engages.
To fit these said loose top burners it is only necessary to pass the air chamber
end through the hole in the stove side and then allow the burner part to rest upon
the bracket with the stud of the one taking into the hole in the other, when the
said burners become detachably affixed in their proper relative positions.

1, HARRY JAMES YATES, of the Firm of Arden Hill and Company of
224 Lichfield Road, Aston, near the City of Birmingham, Gas Stove Manufacturer,
do hereby declare the nature of this invention and in what manner the same is to
be performed, to he particularly described and ascertained in and by the following
statement:
This invention bas relation to detail improvements in the bottom and top burners
of gas cooking stoves, and has for its object, to simplify the fitting or setting in
position of the same without the employment of any loose attachments.
Thus according to my improvements the said burners are made self fitting and
self supporting.
The bottom burners consist essentially of a tubular chamber with a supplementary
tubular air chamber running parallel with the burner and entering the same a short
distance from its middle. The inner end of the burner has an axial hole through
it, wherein the jet of the gas delivery pipe enters, with the nozzle or nipple coming
opposite a gap or air inlet, so that as the air enters the chamber, it intermingles
with the gas prior to the same entering the burner, which has jet or sparting holes
running lignable along its inner side.
Directed along the inside of the back walls of the base of the stove is a
horizontal pipe, whose ends pass through the walls of the opposite sides and form
the termination to a vertical pipe passing from the cross pipe which feeds the top
burners.
This inwardly located pipe which supplies gas to the bottom burners, has at its
two opposite ends and within the boundary walls of the cooker, two projecting
nipples or open ended conical plugs, which fit into the holes in the back ends of the
air chambers of the burners, which are disposed vertically or edgewise and parallel
with and adjacent to the inside walls of the stove.
The front end of each of the burners is closed and comes against a vertical stop
or web lying across a rest pocket formed integral with the stove, whilst coming
above and running in line with the burner is a shelf or outstanding flange, which
hides the burners from view, whilst the top and bottom sides of the burners are or
may be provided with flats or facets, or are made D sectioned at certain points so
as to form flat bearings which come upon outstanding rest flanges carried at any
part of the stove within the range of the burners, which are thereby kept steady.
Thus, each of the burners has a flat near the bend of the air chamber, which is
adapted to come upon a corresponding flat part of a rest bracket directed
horizontally inwards from the base, whilst the topside of the burner has a

page_text: corresponding flat or facet which comes and fits snugly under the shelf, thereby
keeping the fitted burner steady.
I wish it to be understood that I do not limit myself to the positions of the flats
and shelf rests, which may be located at any point most suitable, and further any
similar or equivalent device may be employed for steadying the burners. The
shapes of the pockets may be varied or made so as to accommodate like shaped
ends of the burners, which may fit therein without any liability to displacement.
The gas supply pipe may, if necessary, cross the front of the base of the stove.
In carrying out my invention in connection with top burners, I employ tubular
shaped air tubes, terminated by annular and jet pierced burners, and with the fore
part of each air tube or chamber side gapped to form an air inlet, and with a hole
in the said end which takes over a gas supply nozzle leading from the gas main.
The air chamber ends of the burners rest in holes formed through the sides or
bridge of the top of the stove, whilst the burners rest on outstanding brackets, each
having a hole wherein a stud on the underside of the burner engages.
To fit these said loose top burners it is only necessary to pass the air chamber
end through the hole in the stove side or bridge and then allow the burner part
to rest upon the bracket with the stud of the one taking into the hole in the
other, when the said burners become detachably affixed in their proper relative
positions.
Figure 1 of the accompanying drawings represents in vertical section, a gas-
cooking stove provided with loose top and bottom burners constructed, arranged
and fitted according to one form of my improvements.
Figure 2 represents an underside plan of the stove with parts in horizontal
section upon the dotted line a Figure 1, showing the disposition of the said loose
bottom burners.
Figure 3 is a topside plan of the upper part of the stove, with the mixing
chambers of the burners shown in section.
Figure 4 shows a vertical section of the bottom burner, and an adjacent part of
the stove.
Figure 5 is a vertical section of the lower part of the cooking stove taken
right angles to the section Figure 1, showing how the said loose burners are
supported.
Figure 6 is a side elevation of one of the top burners, and Figure 7 is an
underside plan of it.
Figure 8 is a plan of one of the bottom burners and Figure 9 is an elevation
thereof, whilst Figure 10 is a cross section of the said burner upon the dotted
line 2, Figure 9.
In Figures 1 to 10, a is the shell or body of a single-case stove, with the lower
part a', fitted with a pair of loose burners b, b, directed along the sides, and with
their closed back ends b', resting within pockets or semi-sockets a³, formed in the
back walls of the lower part of the shell of the stove, whilst their front ends b³,
which are double chambered, have end holes 63, which take upon the gas-way
nipples c', of a horizontally directed gas pipe c, supplied through the pipe c³, from
the main supply c³, which is fitted with a regulating tap c
The chamber, of the double-chambered front end b, has an air inlet,
wherethrough atmospheric air passes and intermingles with the gas supplied
through the nipple 63, before the gaseous mixture is emitted into the interior of the
stove through the horizontally directed gas jets 6.
The burners are supported inwardly by shelf rests a³, upon which the broader
parts of the burners come and by the burners coming between the said shelf rests
and parallel flanges a', running preferably throughout the whole length of the
burners (see Figures 1 and 4) the said burners are steadied or prevented from
rocking.
The said bottom burners are provided with baffle shields ', for hooding over the
air inlets and shielding the same from direct draughts.
The top burners d and e, each consist of a tubular air chamber d', c', with their

page_text: forward ends d, e, having end holes or entrances d, e, taking over and being
supported by nipples f, f, of taps f, connected with the gas supply pipe c³ anl
also taking (when not supported by the nipples) through bearer holes a³, formel
within the supplementary sides or bridges a, of the upper part a', of the shell a.
The burner rings d, e, have studs d, e, upon their undersides taking into
holes as, of brackets a, supported from the sides a, of the upper part of the said
shell a.
The said burners d and e have side air-entrances d, e, and by employing the air
entrances at the bottom, the jets are kept steady and protected from abnormal
currents of air passing up the interiors of the burners and putting out the lights.
Thus draughts are baffled in their passage up the air tubes by having to take a
circuitous course instead of a direct one as occurs when the air is admitted
end-wise.
Figure 11 represents a vertical section of a gas cooking stove fitted with a
further form of my improvements.
Figure 12 is a topside plan of the same, with the ends of the burner chambers in
section, whilst Figure 13 is an underside plan, partly in horizontal section, showing
how the loose bottom burners are supported.
Figure 14 is a section of the lower part of the stove, taken at right angles to
that represented in Figure 11.
Figure 15 represents a side elevation and a plan of one of the top burners,
showing the stud on the underside, and
Figure 16 shows a plan, an elevation and a cross section of one of the lower
burners.
In Figures 11 to 16, a is the shell or body part of the stove, with the lower
part a', fitted with loose burners b, whose back ends ', are supported upon
rests a², whilst their front ends 62, which have holes 3, through them, take upon
nipples c', of a gas pipe c. a³ are shelf rests, wherein the burners, which have
jets 6, and bottom air inlets 4, rest and are prevented from rocking or kept
steady by flat parts b', x, on them coming between the upper flanges a and the
shelf rests a³.
To fix the bottom burners in position, slide their open ends over the uipples
and then drop the front or closed ends of the said burners onto their rests, or into
their sockets, when the same become fitted in place and are without any liability
to rock.
The top burners and their cognate parts are marked with the same letters of
reference as in Figures 1 to 10.
By making the burners of the stoves removable, the same are rendered easily
accessible for cleaning purposes, and instead of the brackets of the top burners and
the rests and pockets of the bottom burners being cast integral with the framing of
the stove, they may be made separate therefrom and affixed in any convenient way.
Instead of the ends of the loose bottom burner being round they may be formed
square in cross section and take into corresponding shaped pockets or sockets.
Any number of loose top. burners may be employed, and fitted into position by
the means herein described.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
First. In the loose bottom burners of gas cooking stoves, resting one end within
a pocket, socket, semi-socket or equivalent and supporting the other end or part
upon or by a shelf or rest-flange, or by a hole in the said end taking over a gas way
nipple, substantially as described and set forth.
Secondly. In the loose bottom burners of gas cooking stoves, preventing the
same from rocking by flat or broader parts of the burner coming between pairs
of Hanges coming upon the sides of the stove, substantially as described and
set forth.

page_text: Thirdly. In gas cooking stoves, the means herein described for securing loose
bottom burners in position and preventing the same from rocking, substantially as
set forth.
Fourthly. In the loose top burners of gas cooking stoves, the method of
supporting and fitting the same in position, substantially as described and set
forth.
Fifthly. In the loose burners of gas cooking stoves, making the air inlets at the
sides or at the bottoms near the ends, instead of at the extreme ends, whereby
wind gusts are prevented from directly entering the burners, and also providing
such side air-inlets with baffle shields, substantially as and for the purpose
described and set forth.
Dated this 5th day of October 1896.
