Improvements in Tobacco-pipes.
I, BERNT AARSTAD, of 5, Carl Johansgade, Christiania, Norway, Tobacconist,
do hereby declare the nature of the invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement :-
The object of this invention is the construction of a tobacco-pipe in which means
are provided for cleaning the pipe stem from the nicotine which collects in the same
and in which a cylinder of porous material is arranged for absorbing from the
tobacco smoke as much nicotine as possible. This pipe will not get foul provided
the cleaner is occasionally taken out and cleaned or exchanged for a new one.
The invention is illustrated in the accompanying drawing in which,
Figure 1 is a side elevation partly in section of the improved pipe without the
cleaner.
Figure 2 is a longitudinal section of the pipe with a cleaner arranged in place.
Figure 3 shows the cleaner in side and end elevation respectively.
Figure 4 shows the porous cylinder in side elevation longitudinal section and end
elevation respectively.
Figure 5 shows the loose bottom in plan and cross section.
The bowl A is divided from the hollow stem B by means of a loose bottom C
which rests on a seat c in the lower part of the said bowl. The loose bottom C is
provided with a hole C₁ for the passage of the smoke, the said hole being made
conical to prevent choking. The hollow stem B is made as large as possible and is
not contracted where it joins the bowl but is of the same size throughout. Into
this stem B, is screwed the mouth-piece D the opening in which is also as large as
possible. Within the hollow stem B is arranged the cleaner which consists of a
pin e provided at its end with a disc e¹ and also with a star shaped plate e¹ the said
cleaner may be made of bone or other similar material. Upon the said pin e
outside the plate e¹ is arranged a porous cylinder F of charcoal, blotting-paper or
other porous material for the purpose of absorbing the nicotine. The said cleaner
is so arranged that the plate e' comes inside the hole c' in the loose bottom C so
that when the cleaner is drawn out it will take with it the nicotine ash or other
matter which has collected between the plates e¹ and e". The plate e" is made
star-formed so that it shall not choke the stem, but give the smoke a free passage
to escape round the cylinder. The pin of the cleaner passes for a short distance
into the opening of the mouth piece so that, when the mouth piece is taken off the
said pin can be drawn out by the fingers. When the loose bottom and the cleaner
is taken out the improved pipe can be cleaned better than the pipes which have
hitherto been known.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is :-
First. In a tobacco-pipe the arrangement of a hollow stem opening into the bowl,
the said passage into the bowl being of the same area as the passage in the stem as
above set forth.
Second. In a tobacco-pipe as above mentioned the employment of a cleaner of
suitable material consisting of a pin with one or more discs or plates, which are
arranged in the stem.
Third. In a tobacco-pipe as above mentioned the employment of a porous
cylinder of charcoal blotting paper or other suitable material which is arranged on
the piece of the cleaner.

page_text: Fourth. In a tobacco-pipe as above mentioned the arrangement of a loose
bottom C which divides the bowl from the stem the said bottom resting on a seat c
on the lower part of the bowl as above described and shown in the drawing.
