HENRY SELBY LIESCHING, Peradinia, Crown Hill, Norwood, London S.E. (Of the
Trinity House London,) do hereby declare the nature of this invention to be as
follows:-
The pipe has two bowls, (of which one screws into the other), & is so constructed
that there is a clear space between the two bowls, below the inner one, round its
sides. About one fifth of the inner bowl is filled up with a plug of charcoal or other
absorbent. From just above the level of this plug several holes are pierced in an
upward direction through the thickness of the inner bowl, into the space between the
two bowls. All such nicotine as does not by its own weight sink onto, & get absorbed
by the plug, is drawn with the smoke through the holes, & trickling down the outside
of the inner bowl, drops into the outer one. To prevent the oil in the outer bowl
from getting into the mouth, the stem of the pipe is continued inside the bowl so as to
project right over the accumulated nicotine. This portion of the stem may be either
straight or curved. The advantages claimed are, (1.) No nicotine can get into the
mouth. (2.) The pipe is easily cleansed. (3.) It is a cool smoker."

page_text: I, HENRY SELBY LIESCHING of Peradinia, Crown Hill, Norwood, London, Civil
Servant, 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 drawing forming a
part of this specification :-
The object of my invention is the production of a tobacco-pipe so constructed as to
prevent the nicotine or any noxious liquid from the tobacco being drawn into the
mouth of the smoker, and which can be readily cleansed when required.
My improved pipe is provided with two bowls, one bowl screwing or fitting within
the other; and the said bowls are so formed that when the inner bowl is fitted or
screwed within the outer bowl, there is a cavity or chamber below the said inner
bowl and around its sides. In the bottom of the inner howl may be fitted a plug of
charcoal or other absorbent material. Just above the level of the said plug one or
more holes are pierced or formed through the inner bowl, the said hole or holes
extending in an upward direction from the inner to the outer side of the said bowl
and forming a passage or passages through which the smoke is drawn from the
interior of the inner bowl into the space between the sides of the inner and outer
bowls and thence through the stem of the pipe. The stem of the pipe is continued
inside the outer bowl, thus entering the cavity or chamber formed below the inner
bowl. This extension of the stem may be either straight or curved upward towards
the inner bowl. All such noxious liquid as does not become absorbed by the plug in
the inner bowl, is drawn with the smoke through the holes in the said bowl and
trickling down the outside of the inner bowl falls into the cavity below it, on to the
bottom of the outer bowl and as the inner end of the portion of the stem which
extends into the said cavity is above the level of the accumulated nicotine or noxious
liquid the said nicotine or liquid cannot be drawn through the stem into the mouth
of the smoker.
DESCRIPTION OF THE DRAWING.
Figure 1 is a longitudinal section of my improved tobacco-pipe.
Figure 2 is an elevation of the inner bowl, detached, or removed from the pipe.
Like letters indicate like parts in both figures.
a is the outer bowl of the pipe and 6 is the inner bowl, which either screws into the
top of the outer bowl (as shown in the drawing) or may be fitted therein in any
other suitable manner. The portion of the inner bowl b, which extends into the
outer bowl a beyond the junction of the said bowls, is of smaller diameter than the
cavity of the bowl a and extends only partially into the said cavity, so that, when
the bowls a and b are fitted together, a cavity or chamber c is formed under and
around the inner bowl b. In the bottom of the inner bowl b may be fitted a plug d
of charcoal or other suitable absorbent material. In the sides of the inner bowl bare

page_text: pierced or formed one or more holes e. The inner ends of the said holes are just above
the level of the plug d and the said holes incline from thence upward to the outside of
the bowl b. The said holes thus form passages through which the smoke can be
drawn from the inside of the bowl b into the cavity or chamber c. The plug d may
be dispensed with, if desired, but it will be found useful for the purpose of absorbing
such nicotine as falls by its own gravity thereon. The stem of the pipe has an
extension projecting into the chamber c below the inner bowl b but above the level of
the bottom of the said chamber, and the said extension of the stem may be straight,
or curved upward towards the inner bowl, and may extend upward between the bowls
to or above the level of the holes e. In the pipe shown in the drawing this extension
of the stem is accomplished by means of a tube of vulcanite or other suitable material
fitted, screwed or otherwise secured to the mouth-piece g and passing through the
bore of the stem of the pipe. The inner end f¹ of the said tube f projects into and
across the chamber c below the inner bowl b and above the bottom of the said
chamber. This inner end f¹ of the tube may be straight, of curved as shown, or
curved and extended up the side of the inner bowl b so that its end is on a level with
or above the holes e.
In smoking, such of the nicotine or noxious liquid as does not fall on to the plug d
and become absorbed thereby, is drawn with the smoke through the holes e into the
cavity or chamber e and falls down the sides of the bowl to the bottom of the said
chamber and as the inner end of the projecting portion of the stem within the said
chamber is above the level and extends over the bottom of the said chamber the
accumulated liquid cannot be drawn through the stem into the mouth of the smoker.
A well or cavity c¹ may be formed in the bottom of the outer bowl to further extend
the space for the reception of the nicotine or liquid..
My improvements may be applied to pipes of all forms, sizes and materials and I'
do not confine myself to the method herein described and shown of effecting the
extension of the stem into the chamber c as it will be obvious that this may be effected
in a variety of ways without departing from my invention. Thus, instead of the
stem being formed in one piece with the outer bowl a and having a tube f passing
through it, the stem h or a portion thereof may be made detachable and the portion
of the tube or stem which extends into the chamber c be secured to such detachable
stem or portion of the stem. Or the stem and the extension thereof may, in some
cases, be in one piece so formed that the extension having been inserted through the
outer bowl into the chamber c the stem fits into a socket in the said bowl.
с
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is :-
In a tobacco-pipe, the combination of an outer bowl, an innor bowl 6 having holes or
passages e through its sides, a chamber c within the outer bowl extending under and
around the inner bowl b, and a detachable stem or tube having a straight or curved
extension projecting into the chamber e below the inner bowl, substantially as herein
set forth.
