I, HARRY LOUIS ROSENTHAL of Ackers Street, Chorlton-on-Medlock, Manchester,
in the County of Lancaster, Jeweller, do hereby declare the nature of this invention
to be as follows:-
This invention is designed with the object of providing means inside the stem
or bore of the pipe or holder which will prevent any condensed moisture or
nicotine collecting therein from entering or passing up the mouthpiece by
collecting or retaining it and also to render the cleaning of the pipe stem easy
simple and effective.
The essential feature of my improvements is a tube of spiral or twisted wire
extending from the mouthpiece into the bore of the pipe stem which is made large
enough to receive it the end of such wire tube being preferably flattened and
entering or extending to the bottom of the bowl.
To the screw or other coupling piece of bone vulcanite or other material usually
employed to attach the mouthpiece to the stem of the pipe I affix a small tube
formed of spiral wire or other suitable material presenting a screwed or grooved
surface on the outside and inside.
This tube I now prefer to make of steel wire closely wound in spiral form to be
screwed into the interior of the mouthpiece.
The coupling piece in the end of the mouthpiece is fitted in with a shoulder
and a groove or recess to prevent nicotine travelling up the mouthpiece or the
return of saliva to the mouth.
The spiral wire tube or attachment is preferably screwed into the interior of the
coupling piece but it may be screwed over it or otherwise attached thereto.
The end of the wire tube is preferably flattened or elongated to form a scraper
to clean the interior of the bore and also to prevent particles of tobacco or ash
from entering the tube. A similar wire may be attached to other tubes for the
same purpose.
Instead of the spiral wire tube I may use a tube made of bone wood or other
material formed with both external and internal screw threads of fine pitch or with
other annular grooves or corrugations to arrest or collect the condensed or other
moisture.
The stem of the pipe is made with a bore of larger internal diameter than the
exterior of the tubular screw and this large bore extends nearly into the bowl
preferably tapering off at the entrance thereto so that the tube can also enter the
bottom of the howl.
My improvements may be applied to pipes of any size shape or material.
When in use the nicotine or other condensed matters collect on the exterior and

page_text: interior of the wire tube from which they can be easily removed on withdrawing it
from the stem.

COMPLETE SPECIFICATION.
Improvements in Tobacco Pipes, applicable also to Cigar and
Cigarette Holders.
I, ILARRY LOUIS ROSENTHAL, of Ackers Street, Chorlton-on-Medlock, Manchester,
in the County of Lancaster, Jeweller, 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 is designed with the object of providing means inside the stem
or bore of the pipe or holder which will prevent any condensed moisture or
nicotine collecting therein from entering or passing up the mouth-piece, will
preserve a perfectly free passage for the smoke not liable to get choked up and
will also render the cleaning of the pipe stem easy, simple and effective.
The essential feature of my improvements is a tube of closely coiled spiral or
twisted wire extending from the mouth-piece into the bore of the pipe stem which
is made large enough to receive it the end of such wire tube being preferably
flattened and extending to the bottom of the bowl.
It will be fully described with reference to the accompanying drawing in which
the pipe is shown in longitudinal section.
The mouth-piece A is made in the ordinary way with a coupling or connecting
piece of bone or other material by which it is connected to the stem C of the
pipe and the stem C is made with an enlarged bore c. The coupling piece B may
be screwed externally or otherwise prepared to fit it to the stem C and is also
screwed internally.
To the coupling piece 13 I affix a small tube 1 formed of spiral wire or wire
closely coiled into the form of a spring which presents a screweil or corrugated or
grooved surface hoth externally and internally.
The tube D is made of steel wire closely wound in spiral form and preferably
screwed into the interior of the mouth-piece the interior of the coupling piece
being threaded to receive the end of the spiral wire tube.
The spiral tube may be attached by other means to the mouth-piece such as
being screwed over an end projecting from it.
The end of the wire tube D is preferably flattened or elongated at d to form a
scraper to clean the interior of the bore and also to prevent particles of tobacco or
ash from entering the tube. A similar wire may be attached to other tubes for
the same purpose.
The stem of the pipe is made with a bore of larger internal diameter than the
exterior of the tubular screw and this large bore extends to the bowl so that the
wire tube can also enter the bottom of the bowl.
My improvements may be applied to pipes of any size shape or material, also' to
cigar and cigarette holders.

The screwed or grooved surface of the closely coiled spiral wire tube D arrests
and prevents the nicotine or other condensed matters from passing up the mouth-
piece A consequently nothing but pure smoke can reach the mouth. The flattened

page_text: end d protects the tube ]) from particles of tobacco or ash entering therein thereby
rendering the smoke passage free.
The nicotine or other condensed matter which collects upon the closely coiled
wire tube D can be easily removed when it is withdrawn from the stem C by
burning or otherwise. The tube D can be easily removed and replaced by a fresh
one.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is:
1. A tobacco pipe (a cigar or cigarette holder) constructed with a closely coiled
spiral wire tube extending from the mouth-piece into the stem almost to the bowl
to maintain a free pass therethrough substantially as described.
2. An improved tobacco pipe cigar or cigarette holder constructed substantially
as described and shown.
