Improved Means and Apparatus for Collecting Smut and Smoke
Issuing from Gas and Oil Flames, also from Candles.
I JAMES STOTT of 174 Fleet Street, City of London, Gas Governor Manufacturer
do hereby declare the nature of my said invention to be as follows:-
This invention relates to appliances to be attached to the pendent pipe, to the burner
shell or screen or bracket of a gas burner having a ring, a sun, a star, a flat, an argand
or other form or a combination of flame jets whether the burner be of regenerative
or other arrangement for the purpose of collecting or gathering smut or blacks arising
from the flame as well as for subdueing smoke and for condensing deleterious gases
arising from the flame.
The apparatus is made in sections or divisions of ring or other form of perforated
metal or wire gauze and either left plain or supplied with lime, chalk, pumice stone,
slag wool or other equivalent material or a chemical (compound or other) having an
affinity for collecting impurities thrown off from gas flames.
The apparatus may have gills or projections for gathering or pocketing the smoke
or to retard its passage through or from the apparatus, said gills or projections may or
may not also act as reflectors.
The apparatus above described may be separate from the burner and be suspended
from the upper part of a chandelier or from the ceiling or otherwise and be distinct
from the burner.
The invention as above described is also applicable to oil lamps and to candles, for
the purpose or purposes referred to.

I, JAMES STOTT of 174 Fleet Street, City of London, Gas Governor Manufacturer,
do hereby declare the nature of this invention and in what manner the same is to be
performed to be particularly described anil ascertained in and by the following
statement:
This invention relates to appliances to be attached to the pendent pipe, to the burner
shell, or screen, or bracket of a gas burner having a ring, a sun, a star, a flat, an
árgand, or other form, or a combination of flame jets whether the burner be of
regenerative or other arrangement, for the purpose of collecting or gathering smut or
blacks arising from the flame as well as for subdueing smoke and for condensing gases
arising from the flame.
The apparatus is made in sections or divisions of ring or other form of perforated
metal or wire gauze and either left plain or supplied with lime, chalk, pumice stone,
slag wool, or other equivalent material, or a chemical (compound or other) having an
affinity for collecting impurities thrown off from gas flames.
The apparatus may have gills or projections for gathering or pocketing the smoke
or to retard its passage through or from the apparatus, said gills or projections
may or may not also act as reflectors.
The apparatus above described may be separate from the burner and be suspended
from the upper part of a chandelier, or from the ceiling or otherwise and be distinct
from the burner.
The invention is also applicable to oil lamps and to candle lamps for the purpose
or purposes referred to.
The invention will be understood by reference to the annexed drawings, in which
I show my invention.
Figure shows it in its most simple form, a is a vessel with raised sides and a
perforated or wire work bottom for holding and supporting a film or body of any
material say lime, pumice stone or its equivalent.
The vessel is suspended from a pendent pipe c above the burners d (which are here
shown in star form) so that the smoke and heated gases arising from the flames are
concentrated and caused to pass through the perforated bottom and also through
the material in the vessel whereby the gases and the smoke are purified and all smut
or sooty matter collected.
Figure 2 represents a similar apparatus suspended but made in two halves for easy
removal or adjustment, the two halves are secured by side catches e.
It has a cover f
also perforated or made of wire work, which cover protects the lime or other material
but allows the heated gases to escape. The band or raised side of the vessel may be
ornamented or provided with a corona fixed or moveable and in some cases, said band
may have holes to be more or less closed by turning an outer band to allow the lightest
gas or vapour to escape which the heavy or more concentrated gas or vapour passes
through the vessel and is purified as before mentioned.

page_text: This will be fully understood by the apparatus represented at Figure 3 which is
composed of a perforated or open worked ring band a surrounded by an ornamental
corona b; inside the perforated or open worked band a is another band c similarly
constructed and fitted to be moved round to open or close the perforations d d more
or less as desired, to allow the heated air to escape. The band c has near its upper
part a perforated or wire meshed screen forming a bottom to a vessel g above, for
containing lime, chalk, pumice stone or a chemical compound, this being enclosed by
a cover also perforated, surmounted by a knob i which enables it to be lifted for
renewing the material in the vessel as occasion requires the smoke and noxious gases
arising from the flame are checked slightly, under the perforated bottom and percolate
through the material where they are purified and issue through the perforations in the
cover h as a clear vapour.
Figure 4 is a similar apparatus but with the perforated bottom provided with
deflectors ; which tend to centralize the uprising fumes so that they pass through the
greater thickness of material in the vessel g.
In both these figures the smut collecting and flame purifying apparatus is resting
on the "Comet" globe k of a gas burner, but they are applicable to all kinds of
lamps whether burning gas, oil or candles and it is not necessary that the corona
above described should set upon a globe as it may be hung or suspended over any
existing burner by the ring and links m as shown at Figure 5.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is :-
:-
1. The construction and arrangement of smut collecting and smoke purifying
apparatus as above described and substantially as shown.
2. I claim the apparatus as a smut collector having a perforated bottom and supporting
lime or other agent for collecting smut and purifying smoke of gas and other lighting
flame as described with reference to Figure 1 without a cover also the modified form
with an open work cover as at Figure 2 and whether made in one or more pieces as
set forth.
In a smut collecting or smoke purifying apparatus as before described the application
of two rings provided with apertures capable of being more or less opened to allow
heated vapour to escape and the smoke or sooty particles to pass through the apparatus
as described with reference to Figures 3, 4, and 5.
