I, CHARLES LEE, of Saint Leonard's Vicarage, Bilston in the County of Stafford,
Master of Arts, Clerk in Holy Orders, do hereby declare the nature of this invention
to be as follows:-
This invention has the two-fold object of preventing small particles of tobacco
from being drawn into the month and of enabling the pipe to be readily cleaned
when foul.
These objects are attained, according to this invention, by inserting within the stem
of the pipe, and partly or wholly also, if desired, within the mouthpiece thereof, a
finely perforated tube of metal or other suitable substance having the inner end
entering within the bowl. The tube is conveniently formed of wire gauze, and is
made to fit quite easily down the stem of the pipe and, preferably, so as to leave some
slight clearance between itself and the interior of the stem.
The smoke from the tobacco passes through the perforations into the interior of the
tube and thence through the mouthpiece, and thus fine particles of tobacco are
prevented from passing with the smoke into the tube. When the tube becomes foul,
it may be removed from the pipe, and cleansed by being placed within the fire or
within the flame of a lamp, candle or match; and if it should be desired to clean
also the interior of the stem, this may be readily done by passing the tube when in a
heated condition down the stem of the pipe and thus burning or drying up the foul
residuum collected therein.
The outer end of the tube may be fixed to the mouthpiece, or it may, if preferred,
be carried loosely therein.

page_text: I, CHARLES LEE, of Saint Leonard's Vicarage, Bilston in the County of Stafford,
Master of Arts, Clerk in Holy Orders 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 the letters of reference marked thereon (that is to say):-
This invention has the two-fold object of preventing small particles of tobacco from
being drawn into the mouth and of enabling the pipe to be readily cleaned when
foul.
These objects are attained, according to this invention, by inserting within the stem
of the pipe, and, preferably, partly or wholly also within the mouthpiece thereof, a
tube of wire ganze or an otherwise perforated tube of metal or other suitable
substance. This tube is made to fit quite easily within the pipe and, preferably, so
as to leave some slight clearance between itself and the interior of the stem and
mouthpiece.
This invention will be clearly understood on reference to the accompanying
drawings, of which figure 1 illustrates, in longitudinal section, a tobacco pipe with
my invention applied thereto. The mouthpiece A. is screwed or otherwise fixed to the
stem B, in any ordinary or convenient manner, so as to be readily detachable there-
from and refixable thereto. A tube C, which I prefer to form of wire gauze bent
into shape, or which may be otherwise perforated is inserted within the stem and
enters, preferably, somewhat within the bowl 1 at one end, and extends, when the
mouthpiece is fixed in place as shewn, to within a short distance of the outer end of
the mouthpiece at its other end, and fits easily within the bore of the pipe and mouth-
piece, and, preferably, sufficiently so as to allow some space for the passage of smoke
around its exterior.
The smoke from the tobacco passes in contact with the exterior and interior of the
tube, and any accumulations within the pipe tend to cause the smoke to pass and
repass through the meshes or perforations of the tube as the smoke passes from the
bowl to the mouthpiece. Fine particles of tobacco are thus caught and retained
within the meshes or perforations of the tube, and a considerable proportion of the
nicotine or foul residuum is also deposited upon the surfaces of the tube. When the
tube becomes foul or choked it may be removed from the pipe and cleansed to some
extent on the exterior by being wiped with paper or rag; or it may be thoroughly
cleansed throughout by being placed within the fire, or held within the flame of a gas
jet or burner, lamp, candle, or match; and if it should be desired to clean also the
interior of the stein and mouthpiece this may be readily done by passing the tube,
whilst in a heated condition, down such stem and mouthpiece, and thus burning or
drying up the foul residuum collected therein.
The tube may be closed up sufficiently at one or both ends, if desired, to insure that
no solid particles shall pass therethrough, but this is not found essential in practice as
any solid particles are caught and retained by the perforations during the passage of
the smoke.
This invention may be employed, of course, either for the two-fold purpose above
stated, or simply for the purpose of enabling the pipe to be readily and efficiently
cleaned and when such latter purpose only is desired, the perforations, or the mesh,
may be coarser than when employed for the two-fold purpose; but in any case fine

page_text: perforations, or a fine mesh, is preferred. I find a mesh of about 26 to the inch
answers the twofold purpose admirably.
It is preferred to carry the tube loosely within the stem and mouthpiece, but its
outer end may be fixed within the mouthpiece, if desired.
Instead of forming the tube cylindrical, it may be rolled up from a perforated or
gauze sheet, with the coils of the roll, of course, sufficiently open to allow of the
passage of the smoke therethrough.
A modification of this invention, specially suitable in the case of a pipe formed with
the stem and mouthpiece in one piece, or with the mouthpiece permanently fixed to
the stem, is shewn by figure 2, which is a corresponding view to figure 1. According
to this modification, the perforated or gauze tube (or core) is fixed to a plug E
inserted in the front end of the pipe, so that the plug and tube may be readily
drawn out and replaced through the front end of the pipe. The part a of the plug is
of such a diameter that the tube will readily pass through the hole formed therefor in
the front end of the pipe.
A further modification of this invention, specially applicable also in the case
referred to in the last preceding paragraph, is shown by figures 3 and 4, which are,
respectively, a sectional plan of the mouthpiece end of the pipe, and an end view
thereof. In this modification two wings are fixed to the tube (or core) and enter
corresponding slits within the outer end of the mouthpiece, but so as to very slightly
project sideways from the contour of such end. This projection is shewn in the plan
by a comparison of the broken lines of such contour with the full lines of the wings.
The wings permit of the ready withdrawal of the tube (or core). For convenience of
connecting the tube and wings both the tube and wings may be fixed to a ferrule c
fitting within the mouthpiece.
I am aware that it has been proposed to prepare a tube, perforated around its
circumference, with a surrounding tube or coating of meerschaum, for insertion
within a pipe for smoking, and to renew the meerschaum when it becomes foul; but
I am not aware that such proposal has been carried into effect, and, whether this has
been so or not, it is obvious that the arrangement would not prevent the passage of
fine particles of tobacco, and would not conveniently and efficiently allow of the pipe
being cleaned in the manner in which this is done by my present invention; and,
morcover, such an arrangement would be complex and costly. I make no claim for
a perforated tube within a pipe, otherwise than when used without a coating material
therearound.
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. A perforated tube (or rolled core) within a pipe for smoking, substantially as
herein described, for the two-fold purpose above stated, or simply for the purpose of
enabling the pipe to be readily and efficiently cleaned, as desired.
2. A tube (or rolled core) of wire gauze within a pipe for smoking, substantially as
herein described, for the two-fold purpose above stated, or simply for the purpose of
enabling the pipe to be readily and efficiently cleaned, as desired.
3. The improvements in pipes for smoking, substantially as described with reference
to figure 1 of the drawings herewith.
4. The improvements in pipes for smoking substantially as described with reference
to figure 2 of the drawings herewith.
5. The improvements in pipes for smoking substantially as described with reference
to figures 3 and 4 of the drawings herewith."
