Improvements in Burners for Gas Stoves and Gas Fires.
I, GEORGE ERNEST WRIGHT, Managing Director of John Wright & Co.
Limited, of Essex Works, Thimble Mill Lane, Aston near Birmingham, in the
County of Warwick, Manufacturers of Gas Cooking and Heating Apparatus do
hereby declare the nature of this invention to be as follows:-
My invention has reference to Bunsen burners for gas stoves and gas fires, each
burner consisting of a series of jets arranged in line; and my said invention
consists in the construction and combination of the parts of the said Bunsen burners
hereinafter described whereby alternating jets of the series are made independent
of the other or intermediate jets of the series, so that the combustible gaseous
mixture can be supplied to or cut off from one of the series without interfering
with the other series of jets; or both series can be simultaneously supplied as may
be desired.
According to my invention I make the body of the burner in longitudinal halves
bolted together, but the said body may be made in one casting. The body of the
burner consists essentially of two parallel channels separated by a diaphragm or
partition having in it a series of rectangular recesses open at one side and
resembling generally in shape the ornamental pattern known as the key pattern.
The open sides of the several recesses are in communication alternately with one
or other of the two parallel channels separated by the said diaphragm. In these
recesses the gas jets, arranged in line, are placed so that alternate jets open into
one of the parallel channels and the intermediate jets open into the other parallel
channel.
The gas supply pipes are situated respectively at the open ends of a divided
supply channel parallel to and cast with the herein before described inner channels.
One of the said outer supply channels opens into one of the inner channels and
feeds the combustible gaseous mixture to those jets in connection with it, while the
other outer supply channel feeds the intermediate jets in communication with the
other inner channel. By opening one of the gas supply pipes at the middle of
the burner, alternating jets of the series may be supplied with the combustible
gaseous mixture and by opening the other gas supply pipe, the intermediate jets
of the series may be supplied. By opening both gas supply pipes the whole
of the row of jets may be supplied with the combustible gaseous mixture. In
this way independent control over the two series of jets of the Bunsen burner is
obtained.

I GEORGE ERNEST WRIGHT, Managing Director of John Wright & Co.
Limited of Essex Works, Thimble Mill Lane, Aston, near Birmingham, in the
County of Warwick Manufacturers of Gas Cooking and Heating Apparatus, do
hereby declare the nature of my invention and in what manner the same is to
[Price 3d.1

statement :-
My invention has reference to Bunsen burners for gas stoves and gas fires, each
burner consisting of a series of jets arranged in line; and my said invention
consists in the construction and combination of the parts of the said Bunsen burners
hereinafter described, whereby alternating jets of the series are made independent
of the other or intermediate jets of the series, so that the combustible gaseous
mixture can be supplied to or cut off from one of the series without interfering
with the other series of jets; or both series can be simultaneously supplied as may
be desired.
According to my invention I make the body of the burner in longitudinal halves
bolted together, but the said body may be made in one casting The body of the
burner consists essentially of two parallel channels separated by a diaphragm or
partition having in it a series of rectangular recesses open at one side and
resembling generally in shape the ornamental pattern known as the key pattern,
but recesses of other shapes may be emploved. The open sides of the several
recesses are in communication alternately with one or other of the two parallel
channels separated by the said diaphragm. In these recesses the gas jets arranged
in line are placed so that alternate jets open into one of the parallel channels and
the intermediate jets open into the other parallel channel.
The gas supply pipes are situated respectively at the open ends of a divided
supply channel parallel to and cast with the herein before described inner channels.
One of the said outer supply channels opens into one of the inner channels and
feeds the combustible gaseous mixture to those jets in connection with it, while the
other outer supply channel feeds the intermediate jets in communication with the
other inner channel. By opening one of the gas supply pipes at the middle of
the burner, alternating jets of the series may be supplied with the combustible
gaseous mixture and by opening the other gas supply pipe, the intermediate jets
of the series may be supplied. By opening both gas supply pipes the whole
of the row of jets may be supplied with the combustible gaseous mixture. In
this way independent control over the two series of jets of the Bunsen burner is
obtained.
Figure 1 of the accompanying drawing represents in plan a Bunsen burner for a
gas stove or gas fire constructed according to my invention; Figure 2 represents a
side elevation of the same; Figure 3 represents a longitudinal section of the same
taken on the line A A Figure 1; and Figures 4 and 5 represent cross sections of
the same, the section Figure 4 being taken on the line B, B, Figure 1 and the
section Figure 5 being taken on the line C C Figure 1; Figures 6 and 7 represent
plans of the inner or opposed faces of the longitudinal halves of which the Bunsen
burner Figures 1, 2, 3, 4 and 5 is composed, the edges of the said longitudinal
halves being fitted and fastened together and forming between them the said
burner.
The same letters of reference indicate the same parts in the several figures of
the drawing.
The body of the burner, made of the longitudinal halves a, b, consists essentially
of two parallel channels d, e separated by the diaphragm or division f having in it
a series of rectangular recesses open at one side and resembling generally in shape
the ornamental pattern known as the key pattern. The open sides of the several
recesses of the diaphragm f are marked g and hand are in communication
alternately with one or other of the two parallel channels d and e separated by the
said diaphragm; that is, the open sides of the recesses in the diaphragm ƒ are in
communication with the parallel channel d and the open sides h of the recesses in
the diaphragm fare in communication with the other parallel channel e as indicated
by the arrows in Figure 7.
i, k are the gas jets of the burner arranged in line and made in the upper
longitudinal half a of the burner. The said jets i, k are so arranged in the
rectangular recesses of the diaphragm that alternate jets i, i open by the side

page_text: passages g into the parallel channel d and that the intermediate jets k, k open by
the side passages h, into the other parallel channel e. The alternating jets i, i of
the series are thus made independent of the other or intermediate jets k, k of the
series; 1, m are the gas supply channels opening into and situated parallel to the
inner channels d, e passing to the burners; p, q are the gas supply pipes delivering
gas at both ends and fastened by the arms p³, 7' to the underside of the lower
longitudinal half b of the burner, the said gas supply pipes p, q being situated in
the cut away or divided middle parts r, r of the outer supply channels I, m. The
outer supply channel opens at its ends into the inner channel d and feeds the
combustible gaseous mixture to the alternate jets i, i while the other outer supply
channel m feeds the combustible gaseous mixture to the intermediate jets k, k in
communication with the inner channel e. By opening the gas supply pipe p the
alternating jets i, i of the series may be supplied with the combustible gaseous
mixture and by opening the other gas supply pipe 7 the intermediate jets k, k of
the series may be supplied with the combustible gaseous mixture. By opening
both gas supply pipes p, q the whole of the row of jets i and may be supplied
with the combustible gaseous mixture. Thus, independent control over the two
series of jets of the Bunsen burner is obtained.
Although I have represented a burner composed of two longitudinal halves yet
the burner may be made in one piece; and the shape of the recesses in the
diaphragm or division, into which recesses the gas jets open, may be varied.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed I declare that I claim as my
invention;-
The arrangement or combination herein before described and illustrated in the
accompanying drawing of such Bunsen burners for gas stoves and gas fires as have
their jets arranged in line; that is, making the body of the burner essentially of
two parallel channels separated by a diaphragm or division having in it a series of
open sided recesses preferably of the kind described, into which recesses the gas
jets open, the open sides of the several recesses being in communication alternately
with one or other of the said parallel channels, so that alternate gas jets open by
means of the said recesses into one of the parallel channels and the other or
intermediate gas jets open into the other parallel channel, whereby independent
control is obtained over the two series of jets, the before mentioned parallel
channels being supplied with the combustible gaseous mixture from outer supply
channels and the several parts being arranged and working substantially as
described and illustrated.
