We, GEORGE ASHER, of 98, Lower Edwardes Street, Balsall Heath, Pattern Maker,
and JOHN BUTTRESS, of St. Paul's Road, Sparkbrook, both in Worcestershire, Hotel
Servant, do hereby declare the nature of this invention to be as follows:—
In constructing a wick for an oil lamp or stove according to our Invention we take
an ordinary flat, round or other shaped cotton wick of suitable length and cap or cover
one end thereof with asbestos, such cap or covering extending along the wick to any
suitable distance from that end. Outside the said asbestos cap or cover is a covering
of coarse wire gauze which keeps the asbestos together and in contact with the cotton
wick. The said asbestos capped or covered end protrudes as may be required through
the lamp burner and when lighted the inner cotton wick absorbs the oil to feed the
flame as effectually as an ordinary cotton wick but it is prevented from being
consumed by its cap or covering of asbestos.
Instead of using an outer covering of wire gauze as above described a single strand
or strands of wire may be threaded through and around the end of the wick for
keeping the asbestos and the cotton wick together or an outer casing of perforated
metal may be employed for the same purpose.
The asbestos cap or covering may either be made separately and affixed to the cotton
wick as above described or a cap or covering of asbestos may be formed by weaving or
plaiting asbestos into the end of the cotton wick a wire gauze or other perforated
outer covering being employed to keep the asbestos together as above described.
As our improved wicks as above described do not consume away or require
trimuning many kinds of oil lamps and stoves with which they are used can be
constructed at a much lower cost than heretofore as the means for winding or raising
the wick are not required.

page_text: A burner used with our improved wicks can be placed much nearer to the oil
reservoir without fear of explosion than is possible with an ordinary cotton wick as
the asbestos cap or covering prevents the ascending oil becoming heated.
When constructing a wick for a very wide flame for use with some kinds of stoves
we use a flat cotton wick turned sideways, that is to say, the narrow sides thereof
form the top and bottom of the wick respectively and we cap or cover the upper
narrow side with asbestos similarly as above described with reference to the end of a
cotton wick.

page_text: We, GEORGE ASHER, of 98, Lower Edwardes Stroot, Balsall Heatlı, Pattern Maker,
and JOHN BUTTRESS, of St. Paul's Road, Sparkbrook, both in Worcestershire, Hotel
Servant, 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:
In constructing a wick for an oil lamp or stove according to our Invention we take
an ordinary flat, round or other shaped cotton wick of suitable length and cap or cover
one end thereof with asbestos, such cap or covering extending along the wick to any
suitable distance from that end. Outside the said asbestos cap or cover is a covering
of coarse wire gauze which keeps the asbestos together and in contact with the cotton
wick. The said asbestos capped or covered end protrudes as may be required through
the lamp burner and when lighted the inner cotton wick absorbs the oil to feed the
flame as effectually as an ordinary cotton wick but it is prevented from being
consumed by its cap or covering of asbestos.
Instead of using an outer covering of wire gauze as above described a single strand
or strands of wire may be threaded through and around the end of the wick for
keeping the asbestos and the cotton wick together or an outer casing of perforated
metal may be employed for the same purpose.
When constructing a wick for a very wide flame for use with some kinds of stoves
we use a flat cotton wick turned sideways, that is to say, the narrow sides thereof form
the top and bottom of the wick respectively and we cap or cover the upper narrow
side with asbestos similarly as above described with reference to the end of a cotton
wick.
On the accompanying drawing Fig. 1 represents a flat cotton or other textile wick
capped with asbestos and protected by wire gauze according to our Invention; Fig. 2
is a sectional side elevation and Fig. 3 is a front elevation of the same in position in a
lamp burner; Fig. 4 represents a modified form of the wick illustrated by the
preceding Figures the fibrous inconsummable cap being protected by a strand or
strands of wire; Fig. 5 represents a further modification of the same a peculiarly
shaped outer casing of perforated metal being employed instead of the wire gauze or
strands of wire and Fig. 6 represents separately the sheet metal blank for forming the
said outer casing of the wick Fig. 5; Fig. 7 represents a hollow circular wick
constructed according to our Invention and Fig. 8 represents a very wide neck formed
by the fibrous inconsummable part being fixed to one of the selvage sides of an
ordinary cotton wick.
Referring to Figs. 1, 2 and 3, A is an ordinary cotton or other textile wick
provided at that end which would be exposed to the flame when in use with the cap B
made of fibrous asbestos or other like inconsummable fibrous material. Outside the
said cap B is a wire gauze covering C preferably of a coarse kind sewn or otherwise
connected to the textile part A so as to keep the asbestos or other like material B
together and in contact with the textile part À.
When in use the capped or covered end B protrudes as may be required through

page_text: the lamp burner F (see Figs. 2 and 3) and when lighted the textile part A absorbs
the oil to feed the flame as effectually as an ordinary cotton wick but is prevented
from being consumed by its cap or covering B.
Instead of using an outer covering of wire gauze Cas described with reference to
Figs. 1, 2 and 3 a single strand or strands of wire C' may be threaded through and
around the end of the wick as illustrated by Fig. 4 so as to keep the asbestos or other
like material B together and in contact with the textile part A.
In the modification illustrated by Figs. 5 and 6 a sheet metal outer casing D) is
employed for keeping the fibrous asbestos together and in contact with the textile part A.
The said outer casing is formed of a blank of about the shape illustrated by Fig. 6
which is perforated so as to form narrow vertical bars d which when the blank has
been bent in suitable dies to the shape illustrated by Fig. 5 pass over the top of the
wick from one side to the other. The casing D may be secured to the textile part A
by sewing through the holes e.
Our Invention can be applied to hollow circular wicks similarly as above described
with reference to flat wicks for instance as illustrated by Fig. 7 whichi represents a
hollow circular wick formed of an ordinary textile part A¹ capped with fibrous
asbestos B contained in an outer sheet metal casing D1 perforated so as to form narrow
bars d which pass from the inside to the outside of the wick. The said outer casing
may be formed from sheet metal by successive drawing operations performed in
suitable dies which gradually shape it to the size required and leave an annular space
for the asbestos.
The wick illustrated by Fig. 8 is for use with those lamps and stoves which require
a very wide flame and it consists of a flat textile wick turned sideways so that tho
selvage sides a, a, thereof form the top and bottom of the wick respectively the top
being capped with fibrous asbestos and covered by coarse wire gauze, strands of wire,
or by a sheet metal cap as above described with reference to Figs. 1, 2, 3, 4, 5 and 6.
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:
1st. A wick for an oil lamp or stove, consisting of a lower flat textile wick part A
having a cap B of asbestos or other inconsummable fibrous material protected by a
wire gauze covering C substantially as and for the purposes herein set forth and
illlustrated by Figs. 1, 2, 3 and 8 of the accompanying drawing.
2nd. A wick for an oil lamp or stove, consisting of a lower flat textile wick part A

3rd. A wick for an oil lamp or stove, consisting of a lower textile wick part A
having a cap B of asbestos or other inconsummable fibrous material protected by an

the purposes herein set forth and illustrated by Figs. 5 and 6 of the accompanying
drawing.
4th. A wick for an oil lamp or stove, consisting of a lower tubular textile wick
part A having a cap B of asbestos or other inconsummable fibrous material protected

herein set forth and illustrated by Fig. 7 of the accompanying drawing,
