Improvements. in and relating to Oll Lamp and Oil Stove Wicks.
I, CHARLES SILAS STEMP, of 12, Buckingham Palace Road, London, S. W.
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in and relating to cotton or other wicks,
and the object of my invention is to render cotton or other wicks less combustible,
so that said wicks will require very little, if any, trimming:
In carrying out my invention I steep.a sufficient length of one end of a cotton or
other wick in a solution consisting of boric acid, spirits of ammonia & eosine which
renders said end less combustible.
My improved wick is used in the ordinary manner, the treated end being the one
exposed and ignited and some of the advantages appertaining to my improved
wick are:-
(i) Trimming of the wick may be almost entirely dispensed with.
(2) As my improved wick is much less combustible than ordinary wick, my
improved wick will last a very much longer time.
(3) As my improved wick does not char or become carbonized as an ordinary
wick, the texture and fibre of my improved wick remain practically unchanged,
even when it has been burning for a considerable time, consequently there is a free
flow of oil to the flame and
(4) Inasmuch as my improved wick does, not char or carbonize to any great
extent there is much less likelihood of the air holes and other parts of the lamp
becoming choked or clogged.
I may treat the whole of the wick in the manner described, but inasmuch as
there must be a portion which is never burnt and which enters the oil reservoir
I do not consider it necessary to treat more than a part of the whole wick and in
order that the treated end may be readily distinguished I prefer to dip said 'end
into a suitable dye or colouring or said dye or colouring may be mixed with the
solution referred to so that one dipping will treat and colour the wick,

SLOVE WICKS..
I, CHARLES SILAS STEMP, of 12, Buckingham Palace Road, London, S. W.
Manufacturer, 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 to improvements in and relating to cotton and other wicks
and the main object of my invention is to render cotton or other wicks less
combustible so that said wicks will require very little, if any, trimming.

page_text: In carrying out my invention I steep a sufficient length at one end of a cotton or
other wick in a suitable solution which will render said end practically fire proof
and in order that the treated or fire resisting end of the wick may be more readily
distinguished I prefer to also dip said end in a suitable colouring or dyeing solution
said dye being either mixed with the fireproofing solution so that the fireproofing
and dyeing may be accomplished simultaneously or the wicks may be dyed
separately.
-propor-
The solution which I employ contains boric acid and ammonia and the
tions are about as follows to every gallon of brine I add 2.14 oz. of boric acid
and 3.22 oz. of liquid ammonia fortis and if desired any suitable quantity of eosine
or other suitable dye or colouring matter.
Some of the advantages appertaining to a wick treated as described are:-
1. Trimming of the wick is almost entirely obviated.
2. My improved wick, being almost incombustible lasts much longer than ordinary
wick.
3. As my improved wick does not char or become carbonized as an ordinary
wick, the texture and fibre of my improved wick remain practically unchanged,
even when it has been burning for a considerable time, consequently there is a free
flow of oil to the flame; and,
4. Inasmuch as my improved wick does not char or carbonize to any great extent
there is much less likelihood of the air holes and other parts of the lamp becoming
choked or clogged causing smoke and smell.
I may treat the whole of the wick, in the manner described, but inasmuch as
there must be a portion which is never burnt and which enters the oil reservoir I
do not consider it necessary to treat more than a part of the whole wick and in
order that the treated end may be readily distinguished I prefer to dip said end
into a suitable dye or colouring or said dye or colouring may be mixed with the
solution referred to so that one dipping will treat and colour the wick.
Further advantages appertaining to my improved wick are that, as my improved
wick does not require trimming, it does not become short and cannot, consequently,
"burn short" out of the oil, thereby obviating a very general cause of lamp
explosions viz. -the descending into the reservior of hot vapours or gases from the
hot burner when capillary attraction has ceased, and when the supply of oil to the
said hot burner is cut off..
Further as my improved wick is practically fire proof it does not glow when
the flame is extinguished and consequently does not smoke or smell when
extinguished nor in using my improved wick, can a glowing wick be turned down
into the oil.
My improved wick therefore prevents lamp explosions from the two specified
causes.
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. An improved wick having a portion thereof treated by means of a solution
such as described.
2. An improved lamp wick having a portion thereof treated by means of a
solution such as described said treated end being also dyed or otherwise coloured
all for the purposes and substantially as described.
