COMPLETE DIECIFICATION.
An Improved Device for Holding or Supporting a Chimney of an
Incandescent Gas Burner.
We, JOSEPH WARRY, GEORGE NOEL ARCULUS, and EDWARD ALPEN ARCULUS,
trading in co-partnership as Alfred Arculus and Co., of the Etna Works, 295,
Broad Street, Birmingham, in the County of Warwick, Glass Manufacturers, 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 as hereinafter described to an improved device for hold-
ing or supporting a chimney used in connection with incandescent gas burners
and has for its object to provide means for cutting off the supply of air through
the chimney holder or gallery and introducing same at a point more favorable for
increasing the incandescence of the mantle and thereby obtaining an increase
of light. Our invention will be more clearly understood from the accompanying
drawings the same letters of refcrence indicating similar parts throughout.
Figure 1 shows a front elevation of our improved chimney holder, attached to an
incandescent gas burner made in glass.
Figure 2 is a vertical section of the same.
Figure 3 is a plan of the chimney holder.
Figure 4 is a vertical section of a similar holder made from sheet metal.
Figure 6 is a modification of our invention and Figure 5 a detail view.
A represents an ordinary incandescent gas burner with mantle detached. B is
an ordinary chimney and C the gallery attached to such burner which supports
the chimney holder D which is provided with the projections E, forming supports
for the chimney B. F represents a series of tongue like projections forming inter-
posing scollops or air passages G (when the chimney is in place as shown at
Figure 1) for the introduction of the necessary air supply below the edge of the
chimney B. H represents a disc or ring made from metal, talc, or other similar
material shown separately at Figure 5 having the projections I which are arranged
to rest on the ledge K thus closing up the space between the inside of the base and
the lower part of the mantle and cutting off the supply of air which would other-
wise pass through the galery or holder to the said mantle. The result of thus
cutting off the supply of air from between the base of the holder and the lower
part of the mantle and causing it to be introduced immediately under the bottom
of the chimney to the gas flame, is a considerable increase of the incandescence
of the mantle, giving increased light. In the arrangement shown at Figure 4
which is made from sheet metal we dispense with the projections as shown at E
Figures 1, 2 and 3 and form supports for the chimney B by cutting the metal
and turning the same inwards in the form shown at e. Figure 6 illustrates a
chimney holder made from sheet metal with a contracted part M by which we are
enabled to dispense with talc ring H, the contraction being of a size to close up
the air passage, the openings N in the bottom of the holder are provided so as to
admit air below the burner for the purpose of keeping the holder cool.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
I. A chimney holder for incandescent gas burners, made from glass or metal,
and adapted to supply air to the burner or mantle at a fixed point viz: near the
base of the mantle by means of orifices formed between projecting tongues and
the lower edge of the chimney substantially as described and illustrated in the
accompanying drawings.
II The improved chimney holder for incandescent gas burners consisting of
the body D the tongue like projection F forming the air passages G between
them and the edge of chimney, the projections E or e for supporting the chimney,
and the ledge K, for supporting the metal or tale ring H substantially as described
and for the purpose set forth.
III The combination with an incandescent gas burner of the chimney holder D
claimed above, the chimney B and the metal or talc ring H arranged and com-
bined substantially as described and illustrated and for the purpose set forth.
