Improvements in Tobacco Pipes, and Tubes or Holders for Cigars
and Cigarettes.
I, ADOLPH POSEXER, of 61 Mansell Street, Goodmans Fields, in the County of
London, Merchant, 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, reference being had to the accompanying
drawings and to the letters and figures marked thereon, that is to say :-
My invention relates to improvements in the manufacture or construction of the
pipes and cigar or cigarette holders or tubes set forth in the Specification of my
British Letters Patent No. 17,691, dated 4th November 1890, wherein I described
and claimed the use of pumice stone for the purpose of absorbing nicotine, and
other deleterious juices of the tobacco, and thereby preventing them entering the
mouth of the smoker. I have, however, since found that the commercial pumice
stone is somewhat difficult to manipulate owing to its brittleness, and therefore
requires great care to form it to the necessary shape, and hence the articles made
therefrom cannot be manufactured as cheaply as I desire.
Now, according to my present invention, I overcome these objections by
employing the pumice stone in the form of a powder, combining therewith a suitable
binder or solidifying material, together with any suitable liquid, so as to bring
it into a compound or composition capable of being acted upon to render it suitable
for my purpose, as hereinafter described.
In carrying out my invention I may proceed as follows:--I take powdered pumice
stone, or pumice stone powder, and mix therewith a small proportion of the desired
solidifying agent, say, for instance, plaster of Paris, and I then add thereto liquid
gum, water, or other appropriate liquid. A plastic mass is thus produced which
may be introduced into the bowl of the pipe, or other article, and left therein to
dry and harden. When thoroughly dry and hardened, I then, by means of a
suitable tool, bore or turn out, the the required extent, the hollow necessary to form
the lining and so complete bowl of the pipe. The rods or sticks of absorbent
material described in my previous Specification, and suitable for insertion into the
stem of the articles, may likewise be produced in the same manner as that described
above with reference to the bowls or linings.
Or the plastic mass thus produced may be inserted into the bowl of the pipe, or
into the cigar or cigarette holder, and be then moulded to produce the bowls or
linings for the articles. Or the bowls or linings may be made separately,
turning, and be afterwards inserted into place in the
either by moulding, or
desired article.
Or the entire pipe or tube may, if preferred, be composed wholly of this
plastic material, in which case it could be made in the manner usual in making
clay pipes.
When applying this compound to the stems of pipes, or to cigar and cigarette
tubes or holders, the bore thereof may be made either previously to, or subsequently
to, the formation of or insertion of the bowl or lining into its place.
Although I have instanced the use of plaster of Paris, and liquid gum or water,
1 wish it to be understood that I do not limit myself to the use thereof, as any other
suitable binding material may be used without departing from the nature of my
invention, the essential feature of which is the employment of pumice powder or
powdered pumice stone.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is
1. The use of powdered pumice stone, or pumice powder, combined with a
suitable binder or solidifying agent, and a liquid medium, to produce a composition
or compound capable of being turned, bored or moulded, to form either a fixed or
a removable bowl or lining; or sticks or rods for tobacco pipes and cigar or
cigarette tubes or holders, substantially as described.
2. A lining or bowl for tobacco pipes and cigar or cigarette holders or tubes,
formed from a composition consisting of powdered pumice stone, or pumice powder,
plaster of Paris, and liquid gum (or water), as described.
3. A tobacco pipe, or a cigar and cigarette holder or tube, having a lining or
bowl formed of a composition consisting of powdered pumice stone or pumice
powder, plaster of Paris, and liquid gum (or water), as described.
4. The manufacture and use of tobacco pipes and cigar or cigarette holders or
tubes composed wholly of a composition consisting of powdered pumice stone, or
pumice powder, plaster of Paris, or other suitable binding material, and liquid guin,
water, or other suitable liquid, substantially as set forth.
