IMPROVEMENTS IN TOBACCO PIPES AND CIGAR & CIGARETTE HOLDERS
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I EDWARD JOHNSTONE ALMENT, Manufacturing Chemist of Stratford Bridge
Works, High St Stratford, in the County of Essex do hereby declare the nature of
my Invention for IMPROVEMENTS IN TOBACCO PIPES AND CIGAR & CIGARETTE
HOLDERS to be as follows:-
My invention consists in the first place in providing a receptacle for retaining
and removing from the smoke before entering the mouth of the Smoker a large
portion of the Aqueous Vapour and dark colored foetid oil commonly called
Nicotine which in an ordinary pipe produces the inconvenience known as fouling.
And in the Second place for the removal of the same from the Pipe or tube
without Soiling the fingers.
For these purposes I prepare a cylindrical roll of any porous substance with a
hole running through its centre from end to end, this roll I impregnate by
moistening with a Solution of any substance or chemical Salt having a strong
affinity for aqueous Vapour, owing to its cheapness I prefer the use of Chloride of
Calcium but I do not confine myself to the use of this salt only it is then dried
and covered with a sheathing that is impervious to both moisture and oil.
This cylinder I term a Nicotine Filter The Pipe to be used with this Filter has
the hole running through the stem from the bowl to the mouth peice enlarged to
the same diameter as that of the Filter so that the latter will fill it completely.
To adjust the Filter to its place in the Pipe I divide the latter into two parts by
cutting the stem across at a short distance from the bowl and connecting the same
by a Screw or other suitable joint.
"
After the insertion of the Filter into its place in the stem which it completely
fills, the joint is made tight and the pipe is then fit for use, The Smoke in its
passage from the bowl of the pipe to the mouth of the Smoker, has to pass right
through the Filter where owing to the affinity of the chemical Salt or substance
used, for moisture it condenses by attraction the aqueous vapour from the Smoke
which deposits with itself a large proportion of the thick dark oil of the tobacco,

page_text: commonly called Nicotine when the Filter is saturated it can owing to its oil and
waterproff Sheathing be removed and replaced by a fresh one without soiling the
fingers.
For using the Nicotine Filter with cigars or Cigarettes I place the Filter in a
tube between the mouthpeice of the holder and end of cigar or cigarette.

I EDWARD JOHNSTONE ALMENT of Stratford Bridge Works High St Stratford in
the County of Essex Manufacturing Chemist do hereby declare the nature of my 1
Invention for IMPROVEMENTS IN TOBACCO PIPES AND CIGAR AND CIGARETTE
HOLDERS, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
My invention consists in the first place in providing a receptacle for retaining
and removing from the smoke before entering the mouth of the smoker a large 1
portion of the aqueous vapor and dark colored foetid oil commonly called Nicotine,
which in an ordinary pipe produces the inconvenience known as fouling. And in
the second place for the removal of the same from the pipe without soiling .the
fingers.
For these 'purposes I prepare a cylindrical roll of any porous substance (in 2
preference I use ordinary white blotting paper 'but 'do not confine myself to this
only, as any other porous fibrous substance will answer) with -n hole running
through its centre from end to end, this roll I impregnate by moistening with a
solution of any substance or chemical Salt having a strong affinity for aqueous
Vapour. Owing to its cheapness 'I prefer the uso of chloride of calcium, but I do 2
'not confine myself to the use of this only, it is then dried by heat and afterwards
covered with a sheathing of metal foil or any other substance, impervious to both
moisture and Oil.
This cylinder 'I term a Nicotine Filter The pipe to be used with this filter has
the hole running through the stem from the bowl to the mouth peice enlarged to
the same diameter as that of the filter so that the latter will fill it completely.
To adjust the filter to its place in the pipe I divide the latter into two parts
by cutting the stem across and connecting the same by a screw or other suitable
joint.
After the insertion of the filter into its place in the stem 'which it completely
fills the joint is made tight and the pipe is then fit for use.
The smoke inlits passage from the bowl of the pipe to the mouth of the smoker
has to pass right through the filter where owing to the affinity of the chemical
salt (with which the filter is impregnated) for moisture it condenses by attraction
'the aqueous vapour from the smoke which deposits with itself a large proportion
of the thick dark oil of the Tobacco commonly called Nicotine when the filter is

page_text: saturated it can owing to its oil & water proff Sheathing be removed and replaced
by a fresh one without Soiling the fingers.
For using the Nicotine filter with cigars or cigarettes I place the filter in a tube
between the mouth peice of the holder and end of cigar or cigarette.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is:
The use of a removable filter as already described having a great attraction for
moisture by which a much larger absorption takes place than with an ordinary
porous substance.
Also the covering of the same with a moisture proff sheathing which prevents
the filter from expanding as it gets Saturated, enabling it to be removed from the
pip: without soiling the fingers.
