Improvements in Tobacco Pipes.
I, HENRY DAMER CAPE, of 38, Corbyn Street, Hornsey Road, Hornsey,
London, N., Coal Agent, do hereby declare the nature of this invention to be as
follows:-
The improvements in tobacco pipes, constituting my invention, has for its objects,
the prevention of nicotine generated during smoking from entering the mouth of
the smoker, and the saliva from the mouth of the smoker from coming in contact
with the tobacco in the bowl of the pipe, thereby preventing the waste of tobacco
that usually accumulates in the bottom of the bowl, and which becomes in an
unsmokeable condition solely from this cause, more or less, in all types or forms of
pipes hitherto made and used.
To attain these ends I construct a pipe of any material suited for the purpose,
the bowl of which may be of any desired shape, bored or otherwise hollowed for
the reception of the tobacco but preferably with a larger substance of material
between the bottom of said bore and the outer surface of the bottom of the bowl,
than obtains with tobacco pipes generally the object of this being that, I prefer to
make the smoke passage from the bowl to the stem in a more or less downward
direction, so that any moisture that may get into the stem would have to ascend a
steep incline before reaching the tobacco. The stem may be at any angle
relatively to the bowl, but preferably at right angles, and of any desired length,
and bored or otherwise formed internally to receive the mouthpiece, the particular
construction of which in conjunction with the aforesaid smoke passage in the bowl
attains the object of my invention. The said mouthpiece may be of any material,
and of any shape, and preferably with the exposed part thereof slightly longer
than that of the pipes in general use, and as thin as possible at the mouth end.
The opposite end is made to fit into the stem and may either slide or screw
thereinto as desired, and extends into the stem until it meets or nearly meets
the aforesaid bore in the bowl. One half the length or thereabouts of the mouth-
piece within the stem is circular, while the other portion is semicircular, and lies
at the bottom of the stem, thereby leaving a chamber within the stem at the bowl
end, the said semicircular part is scooped out or hollowed so as to form a channel
and a bore or passage extends therefrom towards the mouth nearly or quite to the
point of junction of the outer end of the stem and the widest part of the mouth-
piece, and then extends in an upward direction through the circular part of the
mouthpiece within the stem, and may or may not cut through the bore of the
mouthpiece, which extends from the circular part within the stem to the end that
enters the mouth, and as far as possible above the aforesaid semicircular channel.
A hole is bored or otherwise formed in the bottom of the said semicircular
channel, and a like hole in the lower surface of the stem, which coincide with each
other when the mouthpiece is in place within the stem, and to the latter hole is
attached outside the stem a suitable cup for the reception of the saliva or moisture
in the stem.
The smoke passage being at the upper part of the stem the nicotine cannot with
ordinary cleanliness accumulate sufficiently to enter the mouth, and any saliva
from the mouth entering the stem would fall into the semicircular channel, and
into the cup, and be easily removed, and the pipe generally easily and quickly

page_text: cleaned. Any suitable mount or ornament may be used at the junction of the
mouthpiece and the stem if desired.

COMPLETE SPECIFICATION.
Improvements in Tobacco Pipes.
I, HENRY DAMER CAPE, of 38, Corbyn Street, Hornsey Road, Hornsey,
London, N., Coal Agent, 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:-
The improvements in tobacco pipes constituting my invention has for its objects,
the prevention of nicotine generated during smoking from entering the mouth of
the smoker, and the saliva from the mouth of the smoker from coming in contact
with the tobacco in the bowl of the pipe, thereby preventing the waste of tobacco
that usually accumulates in the bottom of the bowl, and which becomes in an
unsmokeable condition solely from this cause, more or less, in all types or forms
of pipes hitherto made and used.
In order to render the following explanation of my invention perfectly clear I
have appended hereunto a sheet of drawings in which:-
Fig. 1 is a longitudinal vertical section of one form in which I
propose con-
structing a pipe according to my invention, in which the mouth piece and its
accessories is detached from the bowl stem.
Fig. 2 is a plan view of the said mouth piece and its accessories, while Fig. 3, is a
section of same upon the line A. B.
Fig. 4 is a view shewing the complete pipe, by the junction of the two parts of
Fig. 1.
Fig. 5 is a like view to Fig. 4 but embodying a slight modification of con-
struction.
Fig. 6 is a like view to Fig. 2 but pertaining to Fig. 5.
Fig. 7, is a section of Fig. 6, upon the line C. D.
In carrying my invention into effect I construct of any suitable material in
general use, and of any desired pattern, a bowl A, bored or otherwise hollowed for
the reception of the tobacco, but preferably, with a larger substance of material
between the bottom of said bore, and the outer surface of the bottom of the bowl,
than obtains with tobacco pipes generally, the object of this being that the smoke
passage a, from the bowl A to the stem B, may be in a downward direction, so that
any moisture that may get into B, would have to ascend a steep incline before
reaching the tobacco, which provides that the tobacco may be burned to the last,
without the accumulation of a wet and unburnable mass.
The stem B may be at any angle relatively to the bowl, and of any desired
length, according to the pattern of the pipe, but I have chosen to show, and prefer
to make, the stem at right angles to the bowl, as being better adapted for carrying
out the principles of my invention. The stem B is bored internally to receive and
hold the extension piece C of the mouthpiece D, which may either slide or screw
thereinto as desired. The mouthpiece D may be of amber, bone, vulcanite, or any
of the materials generally used for that purpose, and preferably, slightly longer than
usual in such pipes, and as thin as possible at the mouth end. The extension C may
be of the same material as D or otherwise, and may be screwed or fixed therein in
any suitable manner, or if desired formed integrally therewith, and extends into the
bore in B until it meets, and passes partly under, the bore a. One half the length
of C or thereabouts, is circular and smooth at b, when used as at Figs. 1 or 5, or an
external screw-thread would be formed thereon when this is to be screwed into B

page_text: as at Fig. 4, a like internal thread being of course formed in B. The remainder
of C is semicircular or thereabouts, as at c, and scooped out or channelled, so that
when in position, a cooling chamber is thereby formed inside B. A longitudinal
bore or passage d, extends from c towards, and nearly up to, D, at which point it
may turn in an upward direction through the smoke passage e in C, as at Figs. 1
and 2, or upwards and downwards as at Fig. 4, this cross bore being to facilitate
cleaning. A like smoke passage f is formed in D which coincides with and forms
one continuous passage.
e,
A hole G is bored or otherwise formed in the bottom of c and a like hole in the
lower surface of B, which coincide with each other when the mouthpiece and the
stem are connected, and to the latter hole is screwed or otherwise attached,
outside B, a suitable cup E, for the reception of the nicotine generated during
smoking, or for the saliva or other moisture that may gather in the stem, which
may be easily removed and emptied from time to time as the pipe needs
cleaning.
Or I may adopt the modification shewn by Figs. 5, 6, and 7, in which the length
of b is less than in the previous views which provides the employment of a longer,
and may be deeper channel c, and in this method I dispense with the bore and cross
bore d, and arrange the smoke passage e to take a downward course from before
joining, so that the saliva from the mouth would have to surmount this incline
before falling into c.
C,
and
The smoke from A, passing through a, is partly cooled by the chamber in B
above c, and as the smoke passage e is arranged as high as possible in b, the
nicotine generated would accumulate in c, to the height of e, before any could enter
the mouth of the smoker, which with ordinary cleanliness would not be likely to
and any saliva from the mouth entering into the stem would fall into
from into E, from which it could be easily removed and the pipe generally quickly
and conveniently cleaned, as by the simple removal of the mouthpiece, all the
impurities generated other than that in E, would accumulate in c and be removed
with the mouthpiece, when this was disconnected from the bowl and stem.
occur,
Any suitable mount may be used at F, of precious metal or otherwise as
desired.
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 :-
In an improved tobacco pipe the combination of a bowl A, the bore in the
stem B of which, extends slightly under the bore in A, and connected therewith by
a nearly vertical smoke passage a; a mouth piece D, with extension C, connected
thereto, or formed therewith, and arranged to slide or screw into B, and in which
is formed a semicircular or thereabouts channel c, with or without the bore and
cross bored, and having a hole g through which may pass the impurities generated
during smoking, into and collected by a cup E, screwed or otherwise attached to
the under outer surface of B, the smoke passage e f arranged as at Fig. 4 or as at
Fig. 5, the whole connected and operating substantially as and for the purposes
herein stated, and as described and shewn by the accompanying drawings.
