An Improved Arrangement of Single and Duplex Burners for Gas.
Year: 1886

page_text: I THOMAS HERON of 16 Holborn, in the City of London, Gas Engineer, do hereby
declare the nature of this invention to be as follows:-
The object of this invention, is to arrange single and duplex burners for gas
lamps in such a manner that one part can be easily removable from the other for
the insertion of gauze or like diaphragms in any number to suit pressure and the
amount of light required and thus serve as gas governors or regulators.
The two parts of the burner are formed with rings, one of which can be pushed
into the other to fit gas tight and in the case of duplex burners, screens can be
inserted or made part of said burners so that by turning one part on the other gas
can be made to pass to one nipple for a single flame only a projection, stud, or
other contrivance being fitted to facilitate easy turning.
These divisable gas governor burners can be made to carry the chimney or globe
holder which when the chimney or globe is fastened in place will facilitate the
turning to determine whether one flame or two flames be alight. Said screens can
also be arranged in substitution for the ordinary tap for shutting off the supply or
regulating it this latter part is also applicable to the single nipple burners,

COMPLETE SPECIFICATION.
An Improved Arrangement of Single and Duplex Burners
for Gas.
I THOMAS HERON, of 16 Holborn, in the city of London, Gas Engineer, 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:-
The object of this invention which will be understood by reference to the
annexed drawings, is, to arrange single and duplex burners for gas lamps in such a

page_text: manner that one part a can be easily removable from the other part 6 for the
insertion of gauze or like diaphragms c in any number to suit pressure and the
amount of light required and thus serve as gas governors or regulators. The top
part a of the burner is formed with a ring or milled edge d and can when it is
desired to lower or extinguish the light be pushed into the other part which it fits
gas tight by contact of surface without a screw, and in the case of duplex burners
perforated metal screens can be inserted instead of the gauze diaphragms, or made
part of said burners so that by turning one part on the other, gas can be made to
pass to one nipple for a single flame only, a projection, stud or other contrivance
being fitted to facilitate easy turning.
These divisable gas governor burners can be made to carry the chimney or globe
holder e which when the chimney or globe is fastened in place will facilitate the
turning to determine whether one flame or two flames be alight. Said screens can
also be arranged in substitution for the ordinary tap for shutting off the supply or
regulating it, this latter part is also applicable to the single nipple burners.
Figures 1 and 2 are two views of a burner with one nipple f and a pilot jet g
showing the same turned on or off.
Figures 3 and 4 are plans of the screen c¹ in Figures 1 and 2 respectively When
the burner is alight the jet holes h in the top part a of the burner are over the
corresponding holes in the screen, and on the top part a being turned the boles
come opposite the solid part of the screen and consequently the light is lowered or
put out, a pilot jet may remain burning the gas which leaks between the part a
and screen c¹ or be supplied by a pin hole i
Figures 5 and 6 show two views of the invention applied to duplex burners and
Figure 7 is a part sectional elevation of a modification of the same in which a
pin on the upper part a rides on an inclined lip k to raise said upper part a 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
The improved construction, arrangement and method of operating single and
duplex gas burners as described in relation to the annexed drawings.
The 29th day of October 1886.
