An Improved Tobacco-pipe.
I, ALBERT MOWLAND of 45 Thrush Street, Newington, London S.E
Carpenter and Joiner do hereby declare the nature of this invention to be as
follows:
-―
My invention relates to improvements in the construction of tobacco pipes
which I purpose calling "The Emancipator" and has for its object the pre-
vention of nicotine entering the mouth of the smoker, or saliva therefrom coming
in contact with the tobacco, and also providing a means for easily cleaning the
pipe.
I attain this by constructing a bowl of any suitable material, and of any desired
shape or configuration externally within the substance of which, and near to the
stem thereof, I bore or otherwise form two vertical channels, preferably parallel
with and near to each other, the lower end of one of which enters the bowl near
the bottom, the other into a chamber formed in the stem. A like size horizontal
channel is formed in the upper surface of the bowl which affords communication
between the said channels at their upper ends. An inner casing or lining of any
suitable material is screwed or otherwise fixed within the bowl, and is so formed
that its depth is somewhat less than that of the bowl, so that a space exists
between the bottom of the casing and the interior of the bottom of the bowl, and
within this space terminates the lower end of the first named vertical channel.
The bottom of said casing may be domed, flat or conical and pierced with one or
more small holes. The upper end of said casing is formed with an external
projecting rim, the outer circumference of which coincides with that of the bowl,
and is so arranged as to cover the upper ends of the vertical channels before
mentioned, leaving the horizontal communicating channel perfectly clear, so that
an up and down air tight passage exists between the bowl and the longitudinal
chamber formed within the stem. Into said chamber is screwed or otherwise fixed
a circular plug, provided with one or more (preferably two) longitudinal channels
plugged or otherwise formed solid at their inner ends. A smaller bore is also
formed in said plug extending therethrough which forms with the vertical channels
a passage for the smoke coming from the bowl. The stem may be at any angle
relatively to the bowl, from out the end of which the said plug protrudes and upon
this is screwed or otherwise fixed the mouthpiece, which may be of vulcanite,
amber or any other suitable material and within this a cavity is formed somewhat
longer than the protruding plug, so that when said mouthpiece is close up to the
end of the bowl stem a space exists between the end of the plug and the internal
end of said cavity. A small bore or passage is formed through the mouthpiece,
similar to, and in such a position as to coincide with, and form a continuation
of the smoke passage within the plug. I may form said plug integrally
with the mouthpiece when the material employed will permit, or otherwise as
desired.
The tobacco is placed in the casing within the bowl and lighted in the usual
way. The smoke passes through the hole or holes in the bottom of the casing up
the vertical passage leading from the bowl, along the horizontal channel under the
rim of the casing, down the other vertical passage into the stem chamber,
through the small bores in the plug and the mouthpiece to the mouth of the
smoker.
By reason of the space between the bottom of the casing and the bowl, the
whole of the tobacco may be consumed without any residue, or the gathering of
nicotine, but if, through the non-periodical cleaning of the pipe, which is easily

page_text: performed, nicotine should accumulate, the up and down passage of the smoke,
entirely prevents the possibility of this reaching the mouth of the smoker, and the
space between the outer end of the plug and the interior of the mouthpiece receives
any saliva that may come from the mouth and passes the same into the larger bore
or bores in the plug and prevents the possibility of any portion thereof coming in 5
contact with the tobacco.

COMPLETE SPECIFICATION.
An Improved Tobacco-pipe.
I, ALBERT MOWLAND of 86 Penton Place, Kennington Park Road late of
45 Thrush Street, both in Newington London, S.E. Carpenter and Joiner, 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 :-
My invention relates to improvements in the construction of tobacco pipes,
which I purpose calling "The Emancipator," the objects of my said invention
being that the little nicotine generated during the process of smoking is prevented
from entering the mouth of the smoker, and the saliva from the mouth of the
smoker prevented from coming in contact with the tobacco in the bowl, thus
obviating the usual waste of part of the tobacco placed in the bottom of the bowl,
as is the case with the pipes hitherto made and used. And further, by the
particular construction of the said pipe according to my invention every part
thereof may be quickly and easily cleaned when necessary, which seldom occurs,
from the fact that the whole of the tobacco placed in bowl is consumed without
leaving any unsmokeable quantity in the bottom thereof.
In order that my invention and the manner of its construction may be clearly
and perfectly understood I have appended a sheet of drawings, in which I have
chosen to illustrate my invention in connection with that type of pipe generally
known as the "bull-dog" pattern, although the same is adaptable for, and may
be employed in the manufacture of, any, and every form of pipe at present known
and used.
Fig. 1 is a longitudinal vertical section of a complete pipe, taken upon the
line A B of Fig. 2, which is a plan view of the bowl of Fig. 1 with the internal
casing thereof removed.
Fig. 3 is a longitudinal vertical section of the bowl and stem of same, taken upon
the line C. D of Fig. 2.
Fig. 4 is a longitudinal section of part of the mouthpiece of Fig. 1.
Fig. 5 is an end view of the internal stem plug as it would appear when viewed
from right to left of its position in Fig. 1.
Fig. 6 is a longitudinal section of said plug taken upon the line E. F Fig. 5.
Fig. 7 is a like section of same taken upon the line G. H Fig. 5.
Fig. 8 is an external view of said pipe when the several parts are placed together
ready for use.
In carrying my invention into effect I construct of any suitable material and of
any desired shape or configuration externally a bowl A, the stem of which A¹ may
extend therefrom at any angle and may or may not be formed integrally with A.
Within the substance of A and at the side nearest to A¹, I bore or otherwise form
two vertical channels or tubes or passages a, and b, preferably parallel with and
near to each other, the former of which a would be in such a position within A,
that its lower end would terminate within a chamber B, formed in A', the latter b,
terminates within the bowl A, and at the lower part thereof, and when the material
=

page_text: of which A is composed necessitates that a and 6 have to be bored, 6 would
preferably be of the shape shewn in Fig. 3, so that its lower end may be bored
from the inside of A. A channel c is formed in the upper surface of A, which
connects or forms a continuation between a and b at their upper ends. An inner
hollow cup casing or lining C, of any suitable material is screwed or otherwise
fixed within A, and is so formed that its depth is somewhat less than that of the
interior of A, so that a space exists between the bottom of C, and A, and within
this space terminates the lower end of the channel or bore b. The bottom of C
may be flat, conical, or domed as in Fig. 1, and pierced with one or any number of
small holes d. The upper end of C may extend upwards any desired distance
above the top of A, and may be finished plain or ornamental and externally of any
conformation desired and is formed with a projecting rim so that when C is
screwed or otherwise fixed in position within A, said rim is seated perfectly close
upon the upper surface of A, its out circumference preferably coinciding therewith.
The seating of C upon A in the manner described and shown by Figs. 1 and 8
forms a cover for the horizontal channel c, connecting a, and b, but still leaving c
perfectly clear, so that an up and down air tight passage exists between the
interior of A and the chamber B, and into the latter I screw or otherwise fix a
cylindrical plug D, provided with one or more (preferably two) longitudinal
channels e plugged or otherwise formed solid at the end nearest to A, the said plug
being so arranged that when the bowl A is in an upright position the channel, or
channels e, is, or are in the lowest position within B. A smaller bore or passage f
is formed in D, extending therethrough, which forms with a and b, a passage for
the smoke coming from A when the pipe is in use. The plug D which may be of
any suitable material is of such a length that when in position, a small space,
(preferably) exists between its inner end and the bowl end of the chamber B, as in
Fig. 1, but I may in certain cases arrange D, to fit close up to the inner end of B
and form that end of D to coincide therewith so that and a may be continuous
without a break. The free end of D extends beyond the end of the stem A', and
upon said extension is screwed or otherwise fixed the mouthpiece E, which may
be of vulcanite, bone, amber or any other suitable material, straight or curved in
any way desired, within which a cavity g is formed somewhat longer than the
protruding plug D, so that when E is fixed in position close up to the end of A¹, a
space exists between the end of D, and the inner end of 9. A small bore or
passage is formed in E, similar to and in such a position as to coincide with, and
form a continuation of the bore or passage f. I may in certain cases_form_the
cavity g somewhat less in diameter than the plug D, so that the channel or
channels e is or are partly covered by the solid substance of E, the object
of this being (where necessary) to prevent the return of the saliva that may
collect in e.
When the pipe is to be used the tobacco is placed in C and lighted in the usual
way. The smoke passes through the hole or holes d in the bottom of C, up
the channel b, along c, under the rim of C, down a into B, through f, and 9, and
through E to the mouth of the smoker.
By reason of the space between the bottom of C, and A, the whole of the
tobacco may be consumed without any residue, or the formation of the pasty
matter known as nicotine, and also forms a cooling chamber for the smoke, but if
dust or dirt or other matter should accumulate between C and A this is easily
removed by simply unscrewing C, but such accumulation of matter could not
possibly reach the mouth of the smoker by reason of the channels a and b, and
further by the space between the end of D and B.
but
The saliva that may pass from the mouth of the smoker into the mouthpiece E,
would fall into the cavity g and from there pass into the channel or channels
could not by any possible means come in contact with the tobacco in C, this is too
evident to need further comment, and it will be easily understood that the accuniu-
lation of saliva in e is easily removed by the unscrewing of E, and the pipe
generally easily and quickly cleaned, which will be seldom necessary by reason of

page_text: the perfect combustion of the tobacco in C, and the method and means employed to
prevent the saliva coming in contact therewith.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is,
1st. In an improved tobacco pipe consisting of the several parts herein described
and shewn, combined connected and operating substantially as and for the purposes
set forth and illustrated by the accompanying drawings.
2nd. In an improved tobacco pipe the construction and use of a bowl A of any
suitable material and of any desired shape externally, arranged to receive and hold
by any suitable means, a porcelain, meerschaum or other cup or casing C, resting
by a rim or flange upon the upper surface of A, and provided with a hole or
holes d in the bottom thereof. The vertical bores or passages a and b formed
within the substance of A, the former terminating at its lower end within a
chamber B, in the stem A', the latter terminating at its lower end within the bowl
between the inner surface of A and the bottom of C and communicating at their
upper ends by a horizontal channel c. The cylindrical plug D, provided with a
chamber or chambers e, plugged or formed solid at one end, and a small through
passage f, and screwed or otherwise fixed in B. The mouthpiece E, with internal
passage and cavity 9, arranged to screw upon or otherwise engage with the
protruding end of D, substantially as described herein and shewn by the appended
drawings.
