IMPROVEMENTS IN THE CONSTRUCTION OF SMOKING PIPES SO CONSTRUCTED AS TO ABSORB ALL THE NICOTINE AND MOISTURE
Year: 1884

page_text: I JOSEPH FREDERICK WALSH of Hipperholme in the county of York do hereby
declare the nature of my invention for, "IMPROVEMENTS IN THE CONSTRUCTION OF
SMOKING PIPES SO CONSTRUCTED AS TO ABSORB ALL THE NICOTINE AND MOISTURE,"
to be as follows:-
The object of my invention is to construct a pipe so that it can be smoked
without injury or unpleasantness to the smoker, all nicotine being absorbed and
removed at the will of the smoker, and the pipe cleaned, also any saliva or
moisture, which otherwise gathers in the stem and bowl of the pipe, is absorbed,
and removed.
I carry the stem of the pipe forward into the head, or bowl, and form a place in
the stem for the reception of an absorbent plug, such as a block of blotting paper,
perforated, or a tube of blotting paper, or a tube or block of any other absorbent
material, or an asbestos block which is absorbent, or a perforated block, or tube, of
very soft absorbent pipe clay, the stem of the pipe is like a tube, cut away on the
top side, a third the way down, so as to form a receiver for the absorbent block,
the end which projects into the bowl of the pipe is tubular, and has its hole
preferably in the centre, so as not to be so liable to choke, or, it might be carried
further through, and the hole underneath, or on the low side of the tube, the stem
may either push into the head of the pipe, or may screw into same, and may be
made of any material, metal, composition, bone etcetra.
JOHN E. WALSH,
Agent for the Applicant.

page_text: DESCRIPTION OF DRAWINGS.
Fig 1. is a front elevation of a pipe constructed similarly to Tindell's principle
but it is provided with an absorbent pad or tube and a cooling and condensing
block of Soft pipe Clay, American Corn Husk or other similar suitable substance.
Fig 2. is a plan of the internal stem or tube.
Fig 3. is a front elevation in section of a pipe and tube with absorbent material
immediately under the bowl of the pipe, as well as in the tube.
Figs 4. 5, 6, 6, 7, 8 and 9 shew various forms and shapes of pipes constructed
according to my invention.
I carry the inner stem or tube A of my pipe into and in some cases completely
through the head B of the pipe, and form a place in it for the reception of an
absorbent plug C, such as a block or tube of blotting or absorbent paper or a block
of absorbent Asbestos, Charcoal, pipeclay, or a block or blocks of any two of the
above absorbent materials may be used for the smoke to pass through, the pipeclay
being partially absorbent has as well a cooling and condensing tendency, the paper
asbestos, charcoal or corn husk being to filter the smoke and absorb the nicotine
when the stem or tube containing the absorbent's and cooler or condenser is with-
drawn it brings them with it and all impurities contained therein leaving the other
portion of the pipe comparatively clean and free from nicotine, which in all other
pipes, completely saturates the wood or other portion of the pipe the inner tubes A
I make preferably of a hard material such as metal, celluloid or glass toughened or
untoughened, so that no nicotine or oils can penetrate or saturate the tubes and
they can also be readily and perfectly cleaned the tube passing into the head or
under the bowl or the absorbent may be immediately under the bowl in a chamber E
which can be cleaned and replenished with absorbent without taking out the stem
or tube see Figs 3 and 9. or a separate tube from the smoking tube, may be used
put in from the bowl end of the pipe and containing the absorbent only see Figs 6
and 7 or containing both the absorbent and cooling block see Fig. 8. or the tube
may pass completely through the head under the bowl (see Fig 5) the absorbent
and other material being put in at the head end of the pipe, see Fig 5, the stopper
having attached to it a strip of metal F which passes up the bottom of the tube
and is turned up at the end, to assist in inserting and withdrawing the absorbent
and other material, this strip of metal may be in the form of a trough similar to
those shewn at Figs 6 and 7. when desired, the tube may be of glass wholly or
partly or of other suitable substance.

page_text: Fig. 9 represents the tube also of glass, clay pipes may also be constructed on my
improved principle, the absorbent being put in at the head end of the pipe.
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;-
1 In smoking pipes the use of tubes or partial tubes such as A in combination
with absorbent plugs or blocks such as C, D, in or near the head of the pipe, or
the use of the tube A, see Fig 6 without the plugs all as shewn and described.
2 The use and employment of an absorbent filter pad or pads near or under the
bowl of pipes and as shewn and described.
3 The use and employment of tubes of glass (preferably toughened) for the
purposes shewn and described.
