I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Member of the Institution of Mechanical Engineers, do hereby declare the nature
of this invention to be as follows :-
The improved tobacco pipes, cigar and cigarette holders and other smokers'
requisites, fitted with this filtering or nicotine absorbing device may be of any
suitable shape, size or material.
The main object of the invention is to provide a removable and exchangeable
filtering tube made of blotting paper and intended to be inserted into the stem of
the pipe, at its orifice opening into the bowl; or if applied to cigar or cigarette-
holders, it may be so inserted therein as to project from the front end and form an
extension thereof. Instead of being in the shape of a tube, the filtering device may
assume any other suitable form such as a plug or the like. Any absorbing material
fitted to be used for hygienic purposes may, as before stated, be employed in lieu of
blotting paper. The filtering material, whatever it may be, intercepts the nicotine
and other impurities and thereby renders the smoke harmless and more pleasant to
the taste. When soaked with nicotine it may be readily removed and replaced by
a fresh tube or the like. This I consider a material improvement on the nicotine
intercepting reservoirs or chambers hitherto employed for a similar purpose, as,
where metal is used, it is liable itself to become poisonous and to increase the
danger, while those arrangements invariably spoil the taste of the natural tobacco-
smoke.

COMPLETE SPECIFICATION.
Improvements in or relating to Tobacco Pipes, Cigar and Cigarette
Holders, and the like.
A communication from SYLVAIN DUMONT, of 3, Rue de l'Evêché, Nivelles, in the
Kingdom of Belgium.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Chartered Patent Agent, 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:-
The improved tobacco-pipes, cigar and cigarette-holders and other smokers'
requisites, fitted with this filtering or nicotine absorbing device may be of any
suitable shape, size or material.
The main object of the invention is to provide a removable and exchangeable
filtering tube made of blotting paper and intended to be inserted into the stem of
the pipe, at its orifice opening into the bowl, or if applied to cigar or cigarette-
holders, it may be so inserted therein as to project from the front end and form an
extension thereof. Instead of being in the shape of a tube, the filtering device may

fitted to be used for hygienic purposes may as before stated, be employed in lieu of
blotting paper. The filtering material whatever it may be intercepts the nicotine
and other impurities and thereby renders the smoke harmless and more pleasant to
the taste. When soaked with nicotine it may be readily removed and replaced by
a fresh-tube or the like. This I consider a material improvement on the nicotine
intercepting reservoirs or chambers hitherto employed for a similar purpose, as
where metal is used, it is liable itself to become poisonous and to increase the
danger while those arrangements invariably spoil the taste of the natural tobacco
smoke.
This invention will be best understood by reference to the accompanying drawings
in which
Figures 1 and 2 represent an ordinary pipe with its stem in section.
1
A is the bowl at the bottom B of which is placed a tube C of blotting paper
which serves as a filter and is removably inserted into the stem D. At the end the 1
filtering tube C is retained in position by the mouthpiece E.
Figure 2 illustrates the manner in which the blotting paper filter is applied to
bowls and stems of pipes of any description.
Like letters designate like parts in both figures.
The arrangements shown in Figures 1 and 2 clearly indicate the manner in which
the blotting filters are removably and exchangeably fitted in tobacco pipes and
other similar articles, they being moreover so simple as to require no further
explanation or illustration.
The efficacy of the invention may be increased by lengthening the course or
distance to be travelled by the smoke through pipes and the like and increasing the
"draught" by making the said course spiral instead of straight, and secondly in a
peculiar method of boring or perforating the interior of pipes and similar articles
with a view to better filtering the smoke.
These improvements are shown in the accompanying drawings in which Fig. 3
shows the improved boring applied to a pipe of bent shape. This construction:
facilitates thorough cleaning as the nicotine collected at the bottom may be
removed before it enters the filter, and it also enables pipes or the like, of bent
shape to be made of one piece. As may be seen it consists of inclined channels G
leading to a nicotine reservoir H. The dotted lines I show the additional boring,
leading direct from the bowl A to the outer surface, for cleaning purposes. F is
the filter tube.
Filters. The filters may also be made of cane and terra-cotta.
The screw or spiral arrangement is shown in Fig. 4. It is generally known to
smokers that the longer the distance which the smoke has to travel before reaching
the mouth the more pleasant becomes the smoking. The construction here shown
enables the advantages of a short and portable pipe to be combined with those of a
long stem. Assuming a pipe to be of the shape represented in the drawings the
distance which the smoke would have to travel through the spiral channel would be
more than 30 centimetres, and if the spiral coil extended throughout the pipe, it
would measure from 40 to 45 cm. Thus according to circumstances a pipe, or the 4
like, about 20 cm. long may present a spiral channel of from 30 to 65 cm. for the
smoke to travel through. If applied to a cigar-holder as shown in Fig. 5 the smoke
channel may measure from 25 to 30 cm. To avoid any danger to the health, which
might arise from oxidizing metal, these spiral coils may be made of vulcanized india-
rubber or vulcanite which, as is well-known, is not apt to swell and is as good as s
metal for purposes of screwing or filtering. It will be readily understood that
these spiral coils or channels are, besides calculated indirectly to assist filtration,
and this action may even be enhanced by inserting a piece of cotton-thread into it.
The spiral C is adapted to fit the filter tube F (represented in thick lines
in Fig. 4) which fits into the channel of the stem and may be withdrawn therefrom
after the mouth piece is detached.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion, as communicated to me by my foreign correspondent, and in what manner the
same is to be performed, I declare that what I claim is ;-
1. In pipes cigar and cigarette holders and other similar articles, the employment
of a hygienic filter of highly absorbing material such as blotting paper made in any
suitable shape or size for preventing the nicotine from reaching the smoker's mouth
and thus improving the taste of the tobacco smoke.
2. In a tobacco pipe cigar or cigarette holder or similar article the combination
with a filter such as claimed in the preceding claim of a spirally arranged smoke
duct substantially as described and illustrated in Fig. 4 of the accompanying
drawings.
3. In a bent tobacco pipe cigar or cigarette holder or similar article the
combination with a filter such as claimed in the first claim of a nicotine reservoir
such as H and channels such as G and I substantially as described and illustrated
in Fig. 3 of the accompanying drawings.
