We, HARRY JAMES YATES trading as Arden Hill and Company, of Wharf
Road, Aston, near the City of Birmingham, Manufacturer, and JAMES DAMREL
PRIOR, of Chancery Road, Moseley, near Birmingham, aforesaid, Manufacturer, do
hereby declare the nature of this invention to be as follows:
This invention has reference to atmospheric burners for gas fires and analogous
uses, and has for its object, a duplex burner, which admits of either one or other or
both sets of a double series of teats or burner jets being employed according to the
quantity or volume of heat requiring to be developed.
According to our invention two series or sets of half teats are employed in
connection with a burner, with each series being independently carried by a separate
gas-way or body,' but with both gas ways being controlled by a single tap, cock or
plug, or by two taps.
In carrying out
invention,
our
We make the burner up of two
one set or
series of half nipples,
gas-way elements, one carrying the
and the other carrying or being provided with the second set. The
first series may come in front of the second set, thus forming a
double row of gas jets, each leading to an independent gas-way body preferably
disposed one upon another and both being in communication with a gas supply pipe
which may be controlled by a single cock or tap or each may have its own
independent controlling means.
We propose that the nipples or jets should be half-round, and that the flat sides
of each series should come together, thus forming two rows of duplex or cross-
divided nipples.
.
By thus employing double rows of nipples or half nipples, which preferably come
in pairs one behind the other, the whole of the fuel of a gas fire may be readily
subjected to the gas jets issuing from one set of the nipples and thus be continuously
heated by this one set, but the heating, power of the fuel may be greatly enhanced
or increased when required, by the employment of the flame jets from both sets of
nipples.

Improvements in Atmospheric Burners for Gas Fires and
Analogous Uses.
We, HARRY JAMES YATES, trading as Arden, Hill and Company, of Wharf Road,
Aston, near the City of Birmingham, Manufacturer, and JAMES DAMREL PRIOK, of
Chantry Road, Moseley, near Birmingham, aforesaid, 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:
uses,
This invention has reference to atmospheric burners for gas fires and analogous
and has for its object, a duplex burner, which admits of either one or other or
both sets of a double series of teats or burner jets being employed, according to the
quantity or volume of heat requiring to be developed.
According to our invention two series or sets of half teats are employed in
connection with a burner, with each series being independently carried and supplied
with gas by a separate gas-way or body, with both gas ways and sets of nipples
being controlled either by a single tap, cock or plug common to them both, or by
two separate taps.
Figure 1 of the accompanying drawings represents a top side plan of one form
of duplex atmospheric burners applicable for use in connection with gas fires
and the like, constructed in accordance with our invention. In this particular form,
the
gas supply to both sets of burner nipples is controlled by a single tap.
Figure 2 is an underside plan of the improved burner, showing the arrangement
of the gas passages and the tap for controlling the supply of gas.
Figure 3 is a section of the apparatus, taken upon the dotted line x, Figure 2
and showing the arrangement of the gas inlet fittings of the respective parts of the
burner.
Figure 4 is a view of the said duplex burner showing the same partly in plan and
partly in horizontal section.
Figure 5 is a cross section of the same upon the dotted line a¹, Figure 4.
Figure 6 represents, partly in topside plan and partly in horizontal section one
section or element of the said duplex burner, which carries one series or set of half-
burner nipples and has an independent gas supply and
Figure 7 is a cross section thereof upon the dotted line 2, Figure 6.
Figure 8 represents, also partly in topside plan and partly in horizontal section,
the other sectional part of the said burner carrying the second and independently
supplied series of half burner nipples.
Figure 9 is a cross section thereof upon the dotted lines, Figure 8.
The same letters of reference indicate corresponding parts in the said Figures 1
to 9 of the drawings.
In carrying out this form of our invention, we make the duplex burner a, up of
two superimposed castings or elements and c, the former carrying or being
provided with the one set of series 6, of half burner nipples 62, and the other
element c, carrying or being provided with the second set c¹, of half nipples c². The
first series may, when the two elements are fitted together, come in front of the
second set, thus forming a double row of gas nipples, each leading from the inde-
pendent gas-chamber or passage 63, c, of the separate body sections, which are
preferably disposed one upon another, with their flat sides b, c, coming
together.
The gas for supplying the said double series of half nipples is fed through
separate pipes 65, c, which may either proceed from a common fitting d, and be
controlled by a single cock or tap such as e, as in the arrangement shown, or each
pipe may have its own independent controlling means. The said supply pipes

page_text: respectively terminate in nozzles 66, c, leading to mixing or circulating
chambers b, c, into which atmospheric air is admitted through openings such
as bs, cs, whilst the mixture of gas and air for combustion passes by way of the
radiating passages b, c, to the aforesaid gas chambers 6, c3, from which the
separated series of half burner nipples respectively lead.
This duplex atmospheric burner may be of any shape in outline convenient for
fitting within the bottom of a fire-grate or the like in which it is to be used, whilst
the nipples or jets are preferably half-round or D-shaped, with the flat sides 610, c10,
of each series coming together and thus forming, as it were, a row of duplex or
cross-divided nipples. The said flat sides also form front stop shoulders or sets for
determining the relative position of the super-imposed sections, when fitted
together, whilst a series of lugs such as 6" may also be provided upon the flat face
of the lower section which serve as further means for confining and preventing
lateral displacement of the top section when in position.
We wish it to be understood, however, that we do not confine ourselves to the
particular D-shape of the half-nipples as herein described, as the same may be of
the circular shape represented in Figure 10 and marked c¹, 61, or they may be of
any other figure. Further that instead of making up a duplex burner from two
sections as described we may, where required and if necessary, make up a multiple
burner of any number of superimposed sections, each being provided with a separate
set of nipples independently supplied with gas.
By the employment of a duplex or multiple burner with each of the sections or
parts having an independent gas supply as described, the whole of the fuel of a
gas fire can-at will be subjected to, and continuously heated by, the flames or
jets issuing from one set of nipples, as when only a moderate heat is required, whilst
on the other hand, when the heating power of the fuel is required to be greatly
increased or enhanced, the flame jets from both sets of nipples may then be turned
on and utilized. A further advantage of our improved burner is that there is less
danger of the gas "lighting back" when one of the halves or parts that has been
out of use or turned out is re-lit, as frequently occurs in ordinary duplex burners.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
:-
First A duplex or multiple gas burner, consisting of two or more separate
sections or body parts, each provided with a series or set of burner nipples or half-
nipples and independently supplied with gas by a separate gas-way, with the
whole of the said gas ways controlled either by a single tap or cock, or by inde-
pendent taps.
Secondly -A duplex multiple atmospheric gas burner consisting of two or more
superimposed sections, each provided with a separate set or series of burner nipples
or half burner nipples and independently supplied with gas, with the whole of the
gas supply pipes or passages being controlled either in common by a single tap
or plug, or by separate taps or plugs, substantially as described and set forth.
Thirdly-A duplex burner, consisting of two superimposed sections or parts
with their flat sides coming together and provided respectively with a set or series
of D-shaped or half round nipples, also with their flat sides opposed, with each
section having its independent gas supply, whilst the relative positions of the parts
are assured by lugs and stops arranged substantially as herein described and set
forth in Figures 1 to 9.
