PROVISIONAL SPECIFICATION.
Improved Mouthpiece for Tobacco Pipes and Holders.
I IGNATZ WEISS of 79 Fore Street in the County of London Importer of
Tobacconists' Goods, do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved mouthpiece for tobacco pipes and cigar or
cigarette holders, and has for its object to so construct and arrange the same as to
prevent the passage of nicotine, moisture and the like into the smoker's mouth, yet
providing a clear passage for the smoke and improving the draught.
According to my invention the mouthpiece consists of a tube of any convenient
internal diameter and section to be fixed to the stem in any usual way. For the
open end I construct a plug of configuration in section similar to the tube so as to
pass into it and of any suitable length; a central coned or parallel sided hole is
formed for the smoke, and it may have lateral branches if desired.
The outer end of the plug is enlarged to form the usual holding part for the
teeth, and the inner part is coned or sloped inwardly wholly or in part, or it may
have a shoulder or be otherwise formed of such external shape, that when the plug
is pushed, screwed, or otherwise removably fitted into the end of the mouthpiece
tube, a space or chamber closed at the outer end will be left intervening between
the outer surface of the plug and the inner wall of the tube: said chamber serves
for the deposit and retention of all impurities and prevents their passing through or
obstructing the central smoke hole.
The plug can be readily removed for cleaning purposes, and the draught is
improved by the increased area of the tube.

COMPLETE SPECIFICATION.
Improved Mouthpiece for Tobacco Pipes and Holders.
I IGNATZ WEISS of 79 Fore Street in the County of London, Importer of
Tobacconists' Goods, do hereby declare the nature of this invention and the manner
in which the same is to be performed to be particularly described and ascertained
in and by the following statement :-
My invention relates to an improved mouthpiece for tobacco pipes and cigar
or cigarette bolders, and has for its object to so construct and arrange the same as
to prevent the passage of nicotine, moisture, and the like into the smoker's mouth,
yet providing a clear passage for the smoke and improving the draught.
The mouthpiece consists of a tube of any convenient internal diameter and
section to be fixed to the stem of the pipe or holder in any usual way. For the
open end I construct a plug of configuration and section similar to the tube so as
to pass into it, and of any suitable length; a central coned or parallel hole is formed
for the smoke, and it may have lateral branches if desired. The form of the plug
is such that when inserted an annular or it may be elliptical space or chamber is
formed intervening between the outer surface of the internal projection of the plug
and the inner wall of the tube. I will fully describe my invention in reference to
the accompanying drawings which illustrate in section various forms thereof: P is
the plug or internal projection, T the tube, S the ordinary stem of the pipe or
holder, C the chamber or space formed according to my invention for the purpose
of receiving and retaining nicotine and other impurities. In Figure 1 the plug P

page_text: is shown as coned or sloped wholly. In Figure 2 it is shown as partly parallel
sided with plain surface, and partly coned or sloped. In Figure 3 the same form
is shown but the parallel sided part is screwed; in each case the tube T is
formed to correspond as illustrated; Figures 2 and 3ª are respectively cross
sections on line Y.Z. of Figures 2 and 3 looking towards the open end and showing 5
the chamber C. Figure 4 illustrates a shouldered plug with extended mouthpiece
end. Figure 5 illustrates a plug screwed into the tube T permanently forming a
holed internal projection P and in this form the tube and plug may obviously and
with equivalent effect be made in one piece if desired, but the movable plug is
preferred as affording greater facility for cleaning.
The outer end of the plug P when movable is enlarged to form the usual holding
rim for the teeth; h is the smoke hole which may have lateral branches as dotted
at c Figures 2 and 4, if desired.
When the plug constructed as described is pushed screwed or otherwise fitted
into the end of the tube T, the space C closed at its out er end and open at its inner 1
end as above described is formed. This chamber serves for the deposit and reten-
tion of all impurities and prevents their passing through or obstructing the central
smoke hole h.
Plugs such as are illustrated in Figures 1 to 4 can be readily removed for
cleaning purposes, and the draught is improved by the increased area which can
thus be afforded to the tube T.
Having now particularly described and ascertained the nature of this inven-
tion and the manner in which the same is to be performed I declare that what
I claim is :-
1. A mouthpiece for tobacco pipes and holders constructed substantially as
hereinabove set forth having a space or chamber C closed at its outer end and
intervening between the surface of a plug or annular internal projection such as P
with central smoke hole, and the inner wall of the tube T for the purposes specified.
2. A mouthpiece for tobacco pipes and holders consisting of the combination
with tube T. of a holed plug P so formed and adapted that when inserted in position
a space C is formed in the manner and for the purpose set forth.
