PROVISIONAL SPECIFICATION.
Improvements in Sulphur Candles or Fumigators.
I, CHARLES THOMAS KINGZETT, F.I.C., F.C.S., Analytical Chemist, of
Elmstead Knoll, Chislehurst in the County of Kent, do hereby declare the nature
of this invention to be as follows:-
The object of my invention is to provide a sulphur candle or fumigator which
can be readily ignited. This I effect by partially embedding in the upper surface
of the block of sulphur which forms the body of the candle a strip or strips of
light and preferably openwork fabric such as bobbin net or gauze or muslin which
has previously been steeped in molten sulphur-the fabric is in this way coated
with a thin layer of sulphur which together with the fabric will take fire
immediately that a light is applied to it. A portion only of such coated strip or
strips is embedded in the upper surface of the body of the candle--the remainder is
left standing up from it.
; a
The thin fabric forms a sufficient support for the thin layer of sulphur and when
the portion which stands up from the body of the candle is ignited the burning of
the fabric assists in heating and igniting the sulphur which it carries. The thin
layer of sulphur when ignited runs down on to the top surface of the candle and at
once fires it also.
Instead of using strips of light openwork fabric coated with a thin layer of
sulphur similarly coated strips of tissue paper or other light combustible fabric
may be used or a small mass of cotton wool which has previously been dipped
either partially or entirely into molten sulphur may be employed and made to
adhere to the top of the candle-or straws or other thin or finely divided combustible
material which will leave but little ash when burnt may be used as the support.for
the thin layer or coating of sulphur which is to be first ignited.

Improvements in Sulphur Candles or Fumigators.
I, CHARLES THOMAS KINGZETT, F.I.C., F.C.S., Analytical Chemist, of
Elmstead Knoll, Chislehurst, in the County of Kent, 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 my invention is to provide a sulphur candle or fumigator which
can be readily ignited. This I effect by partially embedding in the upper surface
of the block of sulphur which forms the body of the candle a strip or strips of
light and preferably openwork fabric such as bobbin net or gauze or muslin which
has previously been steeped in molten sulphur-the fabric is in this way coated
with a thin layer of sulphur which together with the fabric will take fire
immediately that a light is applied to it. A portion only of such coated strip or
strips is embedded in the upper surface of the body of the candle-the remainder
is left standing up from it.
The thin fabric forms a sufficient support for the thin layer of sulphur and when
the portion which stands up from the body of the candle is ignited the burning of

page_text: the fabric assists in heating and igniting the sulphur which it carries. The thin
layer of sulphur when ignited runs down on to the top surface of the candle and at
once fires it also.
Instead of using strips of light openwork fabric coated with a thin layer of
sulphur similarly coated strips of tissue paper or other light combustible fabric
may be used or a small mass of cotton wool which has previously been dipped
either partially or entirely into molten sulphur may be employed and made to
-adhere to the top of the candle, or straws or other thin or finely divided combustible
material. which will leave but little ash when burnt may be used as the support for
the thin layer or coating of sulphur which is to be first ignited.
The sulphur coated fabric or other support hereinbefore described which
constitutes what may be termed the "lighter" when employed for the purpose of
setting fire to blocks or candles of sulphur need not necessarily be embedded in
the latter. It suffices for the so-called "lighter" to be placed in juxtaposition to
or superimposed above the surface which it is desired to light. For example the
strips of thin material coated with sulphur may be folded round (outside) the said
blocks or candles as a band either continuous or having free ends resting upon their
upper surface. Or again a small piece or roll of the prepared "lighter" may be
secured on one end of a wire the other end of which passés into the block of
sulphur which is to be lighted in such a way that the said lighter stands above but
quite out of contact therewith. In such case when a light is applied to the
"lighter" it takes fire at once and the burning sulphur then drops or runs down on
to the upper surface of the block or candle of solid sulphur and sets fire to it also.
It is obvious that there are a number of mechanical means whereby the "lighter
may thus be secured to or near the surface of the block or candle of sulphur which
has to be ignited, without actually embedding it therein. When however it is
embedded, as it may be, the block or candle of sulphur only acts as a support for
the "lighter."
"
"
Instead of using prepared materials as hereinbefore described only as "lighters"
for the purpose of setting fire to larger masses of sulphur they may be employed?
in such quantities as to serve themselves for fumigating purposes. For example a
mass of cotton wool may be lightly covered with molten sulphur in such a way
that upon applying a light to any of the projecting edges, fibres or points, the
whole mass will be readily ignited. Again, strips or bands of thin fabrics such as
book-muslin or Brussels net or tissue paper may be prepared of suitable width and
length and after being passed through a bath of molten sulphur so as to coat them
with a thin layer thereof may be made up into rolls or blocks. Such rolls or blocks
will readily take fire on the application of a light thereto and may be used for
fumigating purposes and burnt in any suitable container or vessel made of metal,
earthenware or other material.
In constructing the so-called "lighters" it is not essential to use a combustible
material to support the thin layer of sulphur, although a combustible material is
generally preferable. Fibres of asbestos or thin asbestos cloth or other
incombustible materials may be used so long as the support is coated with a
sufficiently thin layer of sulphur.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. A lighter for blocks or candles of sulphur composed of strips of light
openwork fabrics such as bobbin net, or gauze, or muslin lightly coated with
sulphur.
2. A lighter for blocks or candles of sulphur composed of cotton wool or paper
or such like light fabric lightly coated with sulphur.
3. A sulphur candle or fumigator composed of a block of sulphur having fabrics
or other materials lightly coated with sulphur partially embedded in or held in
juxtaposition to the solid block substantially as described.

page_text: 4. A sulphur candle or fumigator composed of rolls or blocks made from strips
of light and preferably openwork fabrics such as Brussels net or gauze or of
tissue or other paper or from cotton wool lightly covered with sulphur substantially
as described.
