A communication from HERMANN THEODOR EISEN HAUER and ERNST CARL
FRIEDRICH HUNTE, of Toungoo, Burmah, Merchant.
I, ALFRED JULIUS BOULT of 111 Hatton Garden, 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 object of the present invention is a tobacco pipe into which is detachably
inserted a perforated tube or filter.
Unlike the tobacco pipes hitherto in use having a narrow passage between the
bowl and stem which passage becomes easily clogged owing to deposit of dry or
tar like tobacco products and is difficult to clean owing to the inconveniently
narrow means of access in consequence of which the pipe is generally foul or
unpleasant for smoking, in the pipe according to the present invention these
drawbacks are avoided by causing the smoke to enter a very wide passage and
then to pass through an inserted perforated tube.
In the accompanying drawings, Figure 1 shows a short pipe and Figure 2 a
longer pipe and different shape, and Figure 3 a separate view of the perforated
tube according to the present invention.
For this purpose there is screwed on to the end of the pipe stem a or mounted
in any other suitable manner a detachable perforated tube c which enters into the
extension of the bowl b.
This tube c preferably projects with its closed end down to the lower portion of
the interior of the bowl and is provided at this end with several holes or perfora-
tions which enable the smoke to pass freely and completely.
Owing to the larger opening at the bottom of the bowl the latter never or hardly
ever becomes clogged and on the other hand the smoke owing to the possibility
of expansion in the large space becomes cooled by the walls of the part c so that
the smoke is inhaled by the smoker in a cool condition.
When the perforated part of the tube c becomes clogged it is taken out of the
pipe and cleaned by being flushed with water. All the injurious deposits and the
unpleasant taste of an unclean pipe are thus easily removed.
The part c may be used both in short and in long pipes and be made of any
suitable material.
Having now particularly described and ascertained the nature of this 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. A pipe for smoking in which a perforated tube as c detachably secured in the
stem of the pipe projects beneath the interior of the pipe bowl whereby the danger
of the pipe becoming clogged is lessened and the pipe can be easily and thoroughly
cleaned substantially as described.
2. The combination and arrangement of parts constituting the complete pine

of the accompanying drawings.
3. In a pipe for smoking a perforated tube substantially as and for the purpose
described and illustrated in Figure 3 of the accompanying drawings.
Dated this 13th day of September 1897.
