Improvements in Gas Fires and Gas Stoves.
I, WILLIAM COULSON PARKINSON trading as W. Parkinson and Company,
of Bell Barn Road, in the City of Birmingham, Manufacturer, do hereby declare
the nature of this invention to be as follows:-
This invention relates to the burners, or the burner parts, of gas fires and gas
stoves, and which said invention has for its object, the more efficient mixing of the
gaseous matters to be burned, hence more perfect combustion.
The said invention consists first, in the construction or formation of the gas
mixing chamber; secondly, in the construction of the body part of the burner, in
manner, that the gaseous matters in mixing are made to circulate circuitously and
evenly through the said body part, to the jets, which are arranged at intermediate
distances. apart, as may be desired; thirdly, in means of returning the exuberant
amount of gas supplied and thereby preventing the jets or their entrances, becoming
glutted.
economy
This returning of the redundant gaseous matters, affords considerable econ
in the combustion of gas, over burners of gas fires and stoves as ordinarily
constructed, and further, that according to my invention, the atmosphere in the
presence of the said burners, is more pure, consequent upon no unconsumed gas
escaping, as is common with burner of the ordinary construction, and thus it is
that besides economy in the consumption of gas being exercised, apartments in
which gas fires or stoves are more healthy.
In carrying one form of my invention, I make the mixing chamber of the burner,
of a conical figure, tapering outwardly from the inlet, or towards the jets, or the
body of the burner.
By thus forming the chamber, or the inlet part of the burner as described, the
air and burning gas supplied at the entrance to the said chamber, are effectually
mixed in their traverse up the gradually expanding or widening out chamber to the
body of the burner, and from there to the jets or nozzles.
In constructing a silent circulating burner according to another form of my
invention, I make the body part up of three longitudinal chambers, part separated
from each other, to wit, 1st, a taper mixing chamber, 2ndly, a check chamber,.
and 3rdly an outlet chamber, with which latter the jets or nozzles which are
arranged at short distances apart, are in communication.
The partition of the outlet chamber with the check chamber, is open at both
ends, while the partition between the taper mixing chamber and the check chamber,
is open at the off-side end.
The check chamber constitutes a neutral one, wherethrough the redundant
gaseous matters are returned from the near end of the outlet chamber, to the
entrance again of the said outlet, and there intermixes with the newly supplied
gaseous matters traversing up the mixing chamber, which tapers outwardly from
the nozzle or entrance, which is provided with an air hole for the admission of air
at the gas entrance, hence the circulation of the gaseous mixture through the
system of chambers, first traversing up the mixing chamber, then passing the
off-side end of the check chamber to the inlet of the outlet chamber, thence along
the same to the jets, wherethrough the gaseous mixture outwardly passes, and is
burned from the outsides or nozzles of them, whilst the redundant gaseous matters,
are returned and passed through the exit, or rather, the near side entrances to the
check chamber, along the check chamber to the exit of the mixing chamber; thence
as before, mixing with the newly supplied gaseous matters, which are circulated to

page_text: the outlet chambers and burners as aforesaid, hence a silent circulating burner,
without the dissipation of the redundant gases.
In another form of my invention, I make the outlet chamber of the burner bow
figure, with a space or division between the outside walls of it, and the walls of the
check chamber, and further I make the gas entrances to the jets or nozzles, project
or jut inwardly, forming sleeves directed within the inside of the outlet chamber, so
that the jet parts within the outlet chamber, have mouths or inwardly jutting
entrances, directed inwards of the plane of the top side of the said outlet chamber.
I propose that the whole of the entrances to the jets, may be inwardly directed
as described in the last form of my invention.

COMPLETE SPECIFICATION.
Improvements in Gas Fires and Gas Stoves.
I WILLIAM COULSON PARKINSON trading as W. Parkinson and Company,
of Bell Barn Road in the City of Birmingham, Manufacturer, 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:-
This invention relates to the burners, or the burner parts, of gas fires and gas
stoves, and which said invention has for its object, the more efficient mixing of the
gaseous matters to be burned, hence more perfect combustion.
The said invention consists first, in the construction or formation of the gas
mixing chamber, secondly, in the construction of the body part of the burner, in
manner, that the gaseous matters in mixing, are made to circulate circuitously and
evenly through the said body parts, to the jets, which are arranged at intermediate
distances apart, as may be desired; thirdly, in means of returning the exuberant
amount of gas supplied, and thereby preventing the jets or their entrances becoming
glutted.
This returning of the redundant gaseous matters, affords considerable economy
in the combustion of gas, over burners of gas fires and stoves as ordinarily
constructed, and further, that according to my invention, the atmosphere in the
-presence of the said burners, is more pure, consequent upon no unconsumed gas
escaping, as is common with burners of the ordinary construction, and thus it is,
that besides economy in the consumption of gas being effected, apartments in which
gas fires or stoves are burned, are rendered more healthy.
In carrying out one form of my invention, I make the mixing chamber of the
burner, of a conical figure, tapering outwardly from the inlet, or towards the jets,
or the body of the burner.
By thus forming the chamber, or the inlet part of the burner as described, the
air and burning gas supplied at the entrance to, the said chamber, are effectually
mixed in their traverse up the gradually expanding or widening out chamber to the
body of the burner, and from there to the jets or nozzles.
In constructing a circulating burner according to another form of my invention,
I make the body part up of three longitudinal chambers, part separated from each
other, to wit, first, a taper mixing chamber, secondly, a check chamber, and thirdly,
an rutlet chamber, with which latter the jets or nozzles, which are arranged at short
distances apart, are in communication.
The partition of the outlet chamber with the check chamber, is open at both
ends while the partition between the taper mixing chamber and the check chamber,
is open at the off side end.

page_text: The check chamber constitutes, a neutral one, wherethrough the redundant
gaseous matters, are returned from the near end of the outlet chamber, to the
entrance again of the said outlet, and there intermix with the newly supplied
gaseous matters traversing the mixing chamber, which tapers outwardly from the
nozzle or entrance which is provided with an air hole for the admission of air at
the gas entrance, hence the circulation of the gaseous mixture through the system
of chambers, first traversing up the mixing chamber, then passing the off side end
of the check chamber to the inlet of the outlet chamber, thence along the same to
the jets, wherethrough the gaseous mixture outwardly passes, and is burned from
the outsides or nozzles of them, whilst the redundant gaseous matters, are returned
and passed through the exit, or rather, the near side entrance to the check chamber,
along the check chamber to the exit of the mixing chamber, thence as before,
mixing with the newly supplied gaseous matters, which are circulated to the outlet
chambers and burners as aforesaid, hence a silent circulating burner, without the
dissipation of the redundant gases.
In another form of my invention, I make the outlet chamber of the burner bow
figure, with a space or division between the outside walls of it and the walls of the
check chamber, and further, I make the gas entrances to the jets or nozzles, project
or jut inwardly, forming sleeves, directed within the inside of the outlet chamber,
so that the jet parts within the outlet chamber have mouths, or inwardly jutting
entrances directed inwards of the plane of the top side of the said outlet chamber.
I propose that the whole of the entrances to the jets may be inwardly directed as
described in the last form of my invention.
Figure 1 of the accompanying drawings, represents in side elevation, partly in
vertical section, a boiler stove with burner, and having a mixing chamber,
constructed according to one form of my invention.
The said mixing chamber is of a conical figure, and tapers outwardly from the
inlet, towards the jets or body of the burner.
a is the body of the stove, supported upon legs a', and having burner part a³, b is
a conical mixing chamber, having an inlet pipe c, at the middle of its extreme outer
end, and an atmospheric air entrance d.
By thus forming a chamber, or the inlet part of a burner taper, gas and air
supplied at the separate entrances are effectually mixed in their traverse up the
gradually expanding or widening out chamber, and from thence traversed to the
body part a, and afterwards to the jets or burner part.
Figure 2 represents in longitudinal vertical section, a circulating gas fire or gas
store burner, constructed, arranged and provided according to my invention.
Figure 3 is a transverse vertical section upon the dotted lines A B Figure 2,
showing the divisional arrangement of the chambers, consisting of outlet chamber,
check chamber, and mixing chamber, disposed one under the other, and made
continuous by entrances, so that the gaseous matters to be burned are compelled to
circulate in a circuitous manner through the system of long chambers or flues.
a is the burner, b is a taper mixing chamber, with entrance a³, and inlet air
hole d. e is a check chamber, separated from the mixing chamber by an open
ended partition f, whilst g is an outlet chamber, in communication with the nozzles
or jets h.
The outer chamber is divided from the check chamber by a partition i, open at
both ends,, whilst the partition f, between the mixing chamber and the check
chamber, is open at the off side end at j.
The check chamber constitutes a neutral one, wherethrough only the redundant
gaseous mixture or mixtures is or are returned from the near side end ³, of the
outlet chamberg, along the check chamber e, and from thence to the entrance
chamber k, where it intermingles with the newly supplied gaseous mixture, passing
through the inlet j, from the mixing chamber.
It will be understood that the full arrows indicate the direction of circulation of
the supplied gaseous mixtures, whilst the dotted arrows represent the circulation of
the redundant gaseous mixture.

Figure 4 represents a vertical, section of another form of gas fire or gas stove
circulating burner, constructed, arranged, and provided according to a further form
of my invention.
Figure 5 represents a horizontal section of the same, with the burner inverted,
and upon the dotted lines CD.
Figure 6 is a transverse horizontal section upon the dotted lines E F Figure 5.
a is the burner body, b the taper mixing chamber, with gas inlet a', and air
hole'd, at the entrance to the said chamber. e is a check chamber, g the outlet
-chamber, and the nozzles, with inwardly jutting entrances A', whereby the flow
.of
gas is steadied, and the flames emanating from the nozzles or jets are kept
uniform.
The check and outlet chambers are separated from each other by an open
space l.
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 In gas boiler stoves, or in the burners of gas fires and gas stoves,
forming or making the mixing chamber taper, substantially as described and set
forth.
Secondly-In a gas fire or gas stove burner, providing the same with an inter-
vening check chamber, whereby the redundant gaseous products are returned from
the outlet chamber, as set forth.
Thirdly: In a gas fire or gas stove burner, arranging the same with circulating
chambers, comprehending an outlet chamber, having communication with nozzles
or jets, an intervening check chamber, and a mixing chamber or a taper mixing
chamber, arranged constructed and provided as set forth in Figures 1, 2, 3, 4
-and 5.
Fourthly In the nozzles or jets of gas fire, or gas stove, burners, providing or
fitting the entrance to the same with extensions or inwardly jutting sleeves, sub-
stantially as, and for the purpose, described and set forth.
Dated this 17th day of June 1892.
