I, THOMAS BROWN, of 97, Ashton New Road, Bradford, Manchester, Chemist's
Assistant, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved method of cleaning tobacco pipes and con-
sists in providing a special fluid or chemical solution for the purpose.
This special fluid is formed of the following ingredients and in the manner set
forth, viz.:
No. 1 solution. Potass. bicarb. 15 parts, aquae 75 parts.
No. 2 solution. Calcium oxid, 10 parts, aquae 75 parts.
Boil solutions 1 and 2 in two different receptacles, gradually mix and boil them
in a third receptacle and when cold add water to 200 and then draw off the clear
solution into a receiver fitted with a feeding tap.
:
In using the fluid to clean a pipe the bowl is scraped out so as to remove stale
tobacco. A tea-spoonful of the fluid is then poured into the bowl and a small brush
drawn through the stem. The pipe is then washed out thoroughly with cold water
and dried with a cloth when it is ready for use.
My improved fluid instantly removes every particle of nicotine and the con-
centrated impurities from the pipe which are so injurious to the smoker. It also
prevents the pipe imparting a disagreeable odour to the breath and wearing
apparel of the smoker, and can be used without injury to either meerschaum, wood,
or clay pipes.

An Improved Method of Cleaning Tobacco Pipes.
I, THOMAS BROWN, of 186, Wellington Street, Bradford, near Manchester, in
the County of Lancaster, Chemist's Assistant, late of 97, Ashton New Road,
Bradford, near Manchester aforesaid, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement;
This invention has for its object the cleansing of the interior of the stem and
bowl of tobacco pipes from all impurities in the nature of nicotine and the like
which condense therein, by means of the fluid which consists of two solutions
mixed together and manufactured by the following process:-

page_text: '
Solution number 1 consists of 15 parts of potassium carbonate mixed with
75 parts of water. Solution number 2 consists of 8 parts of calcium hydrate to
which is added 75 parts of water. The two solutions are then heated separately
until they boil when solution number one is gradually added to solution number
two, the whole being well stirred meanwhile. The composite solution then
formed is boiled for ton minutes after which it is removed from the stove and
allowed to cool.
The solution must now be allowed to settle when a residue will be deposited on
the bottom of the vessel.
The clear liquid is now drawn off by the use of a syphon.
The liquid is now colourless but for the purpose of distinction from other clear
liquids is slightly coloured brown by placing a piece of cork in a portion of the
liquid until it is coloured when the cork is withdrawn and the coloured liquid
added to the uncoloured portion of which it previously formed part.
The liquid is then bottled in a glass stoppered bottle and is ready for use.
The method of cleaning tobacco pipes with the same is as follows:--A small
quantity of the liquid is poured into the bowl of the pipe and a pipe cleaning
brush or other similar article inserted in the bore of the pipe stem and passed
through the stem into the bowl and then withdrawn. The operation being repeated
several times; the cleaning brush on being withdrawn each time is dipped or
rinsed in water, when instantly all traces of nicotine and other impurities collected
thereon will dissolve and leave the brush perfectly clean.
Water is then poured into the bowl of the pipe and passed through the stem,
after which the stem and bowl will be free from all condensed impurities.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:
1. An improved method of cleaning tobacco pipes and effectually removing
therefrom all impurities condensed in the stem and bowl of the same by means of
the liquid the manufacture of and the method of using which is above described.
2. The fluid produced as above described causes such condensed impurities to
dissolve immediately they come in contact with water.
3. The fluid is noninjurious being without taste or smell, is non-poisonous, &
mon inflamable and that the same has no detrimental effect upon wood, clay,
meerschaum, vulcanite, amber or other materials usually used in the manufac-
ture of tobacco pipes nor upon the usual metal fittings to the same.
4. The fluid produced is an entirely new composition.
