PROVISIONAL SPECIFICATION.
Improvements in Tobacco Pipes.
I BENJAMIN GREEN MARTIN of the Cork District Lunatic Asylum, in the
City and County of Cork, Ireland, Engineer do hereby declare the nature of my
invention to be as follows:-
I form a funell shape piece from metal and insert same some distance down the
bowl of the pipe leaving space between it and the bottom of the bowl. I then
insert a glass tube in the outer stem of the pipe the glass tube protruding a little
into the recess but not tutching the vertical tube.
By this means the objectionable matter will fall through the vertical tube
into the recess beneath and only the pure smoke will be drawn through the
glass tube.
A hole is made at the bottom of the bowl fitted with a stopper for cleaning.
Dated the 5th day of December 1890.

COMPLETE SPECIFICATION.
Improvements in Tobacco Pipes.
I, BENJAMIN GREEN MARTIN of the Cork District Lunatic Asylum, in the
City and County of Cork, Ireland, Engineer 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 :-
This invention has reference to pipes for use in the smoking of tobacco and has
for its object the production of a pipe adapted to facilitate the combustion of the
tobacco and the inhalation of the smoke into the mouth of the user with adequate
provision for the interception of noxious and disagreeable liquid productions also
the formation of the parts of the pipe so that any intercepted matter may be readily
removed and the pipe thoroughly cleansed with great facility.
In carrying out my invention I form the bowl and the stem mainly in one or in
divisible parts with a suitable mouthpiece.
At or about the base of the bowl I provide a removable screw or other suitable
closing plug or stopper fitting a corresponding opening in the bowl and in this
stem preferably attached to the mouthpiece I apply a removeable glass or other
noncorrodible tube or lining through which the smoke is drawn and which tube
when withdrawn can be examined and cleansed as desired. This tube I prefer to
project, when in place, just slightly into the bowl.
The tobacco filled into the pipe will rest upon a false or removeable floor or
bottom piece. This removeable piece preferably consists of a dished or concave
plate or floor having a central opening and tubular continuation or there may be
more than one such opening.
In use the smoke from the ignited tobacco with other products of combustion
passes down into the catchpit or intercepting chamber from which the smoke passes
away by the mouth tube whilst the liquid and solid matters are intercepted.
Again, any saliva passing down by the mouth tube is similarly intercepted.

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 shews a side view of the pipe with the portion of the stem shewn in
section and with part of the bowl represented as being broken away so as to shew
the removeable floor or bottom piece d in the bowl.
Figure 2 indicates an underside view and Figure 3 a sectional view of the
removeable floor d separately.
a indicates the bowl portion of the pipe, the stem which may terminate in any
suitable mouthpiece.asb. The base of the bowl has an opening internally threaded
or fitted so as to receive a screw stopper or as-shewn a tight fitting plug capable
of removal when desired. d is the removeable support for the tobacco having a
central somewhat tubular passage d'. e is a small tube of glass or other suitable
noncorrodible material attached to the mouthpiece b' if preferred to facilitate
removal, or the mouthpiece b' may simply serve as a guard to this tube, the tube
itself being capable of withdrawal for cleansing. The tube e is preferably as shewn
allowed to project slightly into the catchment chamber formed below the floor d
and in which chamber objectionable matters will be trapped and retained for
removal on taking out the plug c.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a tobacco pipe a bowl and stem in combination with a loose or removeable
floor d a lining tube e and closeing plug c, substantially as described and shown.
2. The combination or arrangement, with a tobacco pipe having a removeable
plug closeing and opening in its bowl and a removeable floor adapted to form a
catchment chamber and a lining tube removeable for cleansing as set forth.
3. A tobacco pipe constructed and arranged so as to facilitate interception of
foul matters and facilitate cleansing as set forth.
