We CORNELIUS CRASTIN, of 185, Hornsey Road,, in the county of Middlesex,
Engineer, and WILLIAM BEALE, of 370, Holloway Road, in the county of Middlesex,
Pastry Cook and Confectioner do hereby declare the nature of this invention to be as
follows:-
This invention consists in the use for lamp wicks of all kinds, of carbon, preferably
of the kind known as flexible carbon, that is to say, carbon produced according to the
specification of F. H. Varley's Patent No. 2,776 of 1882.
In order to enable us to make use of the said material for lamp wicks, the carbon
may be manufactured into pieces of the required length and shape, or in the case of
flat wicks, the same may be cut into the required lengths and widths.
The wick tube is of the ordinary construction, but the carbon wick is placed
within an additional tube which works within an enlarged continuation of the wick
tube; the lower part of the additional tube is perforated. The additional tube does
not extend to the upper part of the wick and its object is to protect the wick and to
allow of the same being raised and lowered by suitable means, such as by a pinion and
rack arrangement.
The additional tube can be provided with a stop to limit the play thereof.
In some cases we apply to the lower end of the carbon wick an ordinary cotton or
like wick as a feeder.
Suitable means (such as a spring) are provided to prevent the wick tube from
falling by its own weight.

Improvements in and Connected with Lamps.
We, CORNELIUS CRASTIN, of 185 Hornsey Road, in the County of Middlesex,
Engineer, and WILLIAM BEALE, of 370 Holloway Road, in the County of Middlesex,
Pastry Cook and Confectioner, 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 consists in the use for lamp wicks of all kinds of carbon, preferably-
of the kind known as flexible carbon, that is to say, carbon produced according to the
Specification of F. H. Varley's Patent No. 2,776 of 1882, the object of the invention
being to provide a wick which will not require to be trimmed and will therefore last❤
for a much longer time than an ordinary wick.
In order to enable us to make use of the said material for lamp wicks, the carbon
may be manufactured into pieces of the required length and shape or in the case of
flat wicks, the same may be cut into the required lengths and widths.
A burner having an ordinary wick tube is employed but the carbon-wick is placed
within an additional tube which in some cases extends into and works within an
enlarged continuation of the said wick tube; the lower part of the additionable tube
is perforated. The object of the additional tube is to protect the wick and to allow of
the same being raised and lowered by suitable means, such as by a pinion and rack
arrangement.
The additional tube can be provided with a stop to limit the play thereof.
In some cases we apply to the lower end of the carbon-wick an ordinary cotton or
like wick or wicks as a feeder.
Suitable means (such as a spring) are provided to prevent the carbon-wick tube
from falling by its own weight.
In order to enable our invention to be fully understood we will describe how it can
be carried into practice by reference to the accompanying drawing in which figure 1
is a section of a lamp burner provided with a carbon-wick according to our invention
and with a wick tube (shown in elevation) adapted for use with the same; figure 2 is
a transverse section of figure 1; figure 3 is a detached elevation of the carbon-wick
tube and figure 4 is a transverse section thereof. Similar letters in all the figures
represent similar parts.
a represents our wick made of carbon preferably of the kind known as flexible
carbon as hereinbefore described and b is the tube in which the same is contained the
lower part of the said tube being perforated as shown; c is the usual wick tube of
the burner enclosing our additional carbon-wick tube b; dis the enlarged continuation
with which we provide the usual wick tube c, the bottom thereof forming a stop for
preventing the tube b from being lowered too far.
e is the rack and fff are the pinions for raising and lowering the carbon-wick
tube b, the said rack advantageously consisting of a number of depressions stamped in
the carbon-wick tube b.

page_text: gg are the ordinary cotton or like wicks which we in some cases apply to the lower
end of the carbon-wick, the wicks g g being advantageously secured in the enlarged
continuation d of the wick tube over the perforations of the carbon-wick tube b, as
clearly shown in figure 2 and serving to feed the oil to the carbon-wick a.
h is the spring situated in a recess made in the ordinary wick tube c and bearing
against the carbon wick-tube b for the purpose of preventing the latter tube from
falling by its own weight.
Although we have described and illustrated our carbon wick provided with
ordinary cotton or like wicks for feeding the same the said ordinary wicks are not
indispensable and we therefore do not in all cases make use of them.
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 :-
1. A wick made of carbon preferably of the kind herein referred to, for use in
lamps substantially as hereinbefore described.
2. The use in combination with an ordinary cotton or like wick or wicks of a wick
made of carbon preferably of the kind herein referred to substantially as hereinbefore
described.
3. The arrangement of wick tubes and means for raising and lowering carbon-
wicks substantially as hereinbefore described and illustrated in the accompanying
drawing.
