Improvements in Tobacco Pipes.
I, WILLIAM YOUNG YATES, of Railway House, Irlums o' th' Heights, in the
County of Lancaster, Engineer, do hereby declare the nature of this invention to
be as follows:
This invention has for object to so construct a pipe that when desired nicotine
and the like may be readily discharged from the bore thereof and a jet of smoke
be obtained for the purpose of fumigating plants to destroy insects thereon and for
disinfecting purposes. For this purpose I extend the bore of the pipe beyond its
junction with the aperture in the bottom of the bowl, carrying it to the exterior of
the body thereof so that upon blowing through the bore air or smoke, according
to whether the pipe be lighted or not, will be drawn from the bowl into the bore
and discharged together with any nicotine or juices therein through the open end
thereof.
According to one construction the bore of the pipe with the bowl from about the
point where it communicates is of gradually increasing diameter towards the mouth
piece and of gradually decreasing diameter towards its other open end which is
if
provided with a plug or other closure. The tapering portions of the bore
may
preferred be separated by a cylindrical portion of considerable diameter into which
the passage from the bowl leads.
Instead of the bore being formed as described it may be cylindrical throughout
and the mouth piece be provided with a nozzle adapted to fit the bore and to
extend to the passage from the bowl or thereabouts, a short tube which may be of
conoidal internal section, and is provided with a plug or cap, being fitted into the
end of the bore furthest from the mouth piece.
Tobacco pipes constructed as above described can be rendered sweet and clean
after smoking by blowing through the mouth piece whilst a small quantity of
lighted tobacco is still left in the bowl, the heat from which softens the nicotine or
the like which is then easily ejected.
On lighting the tobacco in such a pipe air may be blown through the stem instead
of being drawn in the reverse direction through the bowl as is generally done, thus
avoiding obnoxious fumes being drawn into the smoker's mouth.

Improvements in Tobacco Pipes.
I, WILLIAM YOUNG YATES, of Railway House, Irlams o' th' Heights, in the
County of Lancaster, Engineer, 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 has for object to so construct a pipe that when desired nicotine

page_text: -
and the like may be readily discharged from the bore thereof and a jet of smoke
be obtained for the purpose of fumigating plants to destroy insects thereon and for
disinfecting purposes. For this purpose the bore of the pipe instead of terminating
at its junction with the aperture in the bottom of the bowl is extended to the
exterior of the body thereof so that upon blowing through the bore from the
mouthpiece end, smoke or air according to whether the pipe is lighted or not, will
be drawn from the bowl into the bore and discharged together with any nicotine
or juices therein through the open end thereof.
In the accompanying drawings,
Fig. 1 is a longitudinal section, partly in elevation, showing one construction of
pipe according to my invention, and Fig. 2 is a horizontal section of the detachable
mouth piece with which such pipe is provided.
As will be seen the bore a extending through the pipe stem a' does not terminate,
as is usual, at the aperture 6 by which it communicates with the pipe bowl c but is
extended onward as shown at a² to the exterior of the base of the pipe bowl, the
bore a being of gradually increasing diameter outwardly from its end adjacent to
the said aperture 6 to its outer end whilst the extended bore a which in the
example shown is formed by a metal lining a³ is of gradually decreasing diameter
from the said aperture to its outer end where it is normally closed by a cap a' or it
may be by any other suitable closure, such as a plug. As will be seen the
arrangement of the bores a a² is such as to form two nozzles of gradually
decreasing cross section from right to left the one being arranged to deliver into
the other so that upon air being blown through the one forming the bore a the
cap a being previously removed, it will issue therefrom in the form of a jet which
will be projected under considerable pressure into the central portion of the other
nozzle forming the bore extension a whereby an effective inducing action will be
set up through the aperture with the result that smoke or air, according as the
pipe is alight or not, will be drawn through the aperture 6 into the space around
the issuing air jet and be discharged with such air jet through the outer and
smaller end of the bore a², In this way the pipe can be rendered sweet and clean,
the more so if lighted tobacco be in the pipe bowl at this time, as the heat carried
away therefrom by the smoke will serve to soften nicotine or other like matter
that may have collected in the bottom of the "pipe. In the latter case also a jet of
smoke can be readily produced for fumigating plants or other articles. A further
advantage is obtained by making the bores a and a' of the form described and
shown, viz., that a receptacle is formed below the aperture into which nicotine or
other noxious matter will pass and be retained without liability of its pas.ing
through the bore a to the mouth piece when the pipe is being smoked.
b
In the example shown in Figs. 1 and 2, the outer end of the bore a is made
sufficiently large to receive the mouth piece d, the bore in which is preferably also
of increasing cross sectional area in an outwardly direction as shown in Fig. 2, but
it may be of unitorm diameter throughout if desired.
If the bowl is of wood, a bush e of metal or other suitable substance is preferably
employed to prevent the aperture & becoming enlarged by the burning away of
its wall.
Fig. 3 illustrates a modification in which the bore a through the pipe stem is of
cylindrical form throughout its length, and the mouth piece d is provided with a
Dozzle a which extends to the aperture 6 or thereabout and is arranged centrally
with reference to the conical bore extension at which is formed by a lining a, as
in the previous case, closed at the outer end by a removable plug a'. In this
arrangement the bore of the nozzle a is of uniformn cross section throughout its
length, but the outside of the nozzle is of diminishing cross sectional area towards
the aperture so that a space is left into which nicotine and the like will fall and
so be prevented from being drawn into the smoker's mouth, while at the same time
the arrangement is such that on removing the plug at and blowing through the
stem, such deleterious matters can be readily ejected.
Fig. 4 represents an arrangement resembling that illustrated in Fig. 3 but in

page_text: which the mouth piece is provided with a nozzle a* that fits the hollow cylindrical
stem of the pipe for the greater portion of its length and is provided at its inner
end with a short centrally arranged portion of smaller diameter than the remaining
portion, and which terminates in proximity to the aperture b. aº is a cylindrical
portion of the bore arranged between the nozzle a* and the conical bore extension
so as to serve as a receptacle for retaining nicotine or the like, as in the other
examples.
The lining a³ does not in this case extend past the aperture 6, although it may
do so if desired, in which case it must, as in the preceding arrangements, be formed
with a hole corresponding to the aperture b. As will be obvious the linings in
Figs. 1 and 2 may be shorter than shown, so as not to extend to the aperture b.
Fig. 5 shows partly in longitudinal vertical section and partly in elevation, and
Fig. 6 in horizontal section a pipe similar to that shown in Fig. 1, except that
the pipe bowl, stem and mouth-piece are formed of one piece of material such as
asbestos or clay, and the metal protective bush e and lining a³ used in the pipe
shown in the said Fig. 1 are dispensed with.
On lighting the tobacco in a pipe constructed as described, air may be blown
through the stem and bore extension a¹ instead of being drawn in the reverse
direction through the stem as is generally done, thus avoiding obnoxious fumes
being drawn into the smoker's mouth.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is :-
i. A tobacco pipe in which the bore through the pipe stem is extended beyond
the aperture communicating with the interior of the pipe bowl, to the exterior of
the base or body of the bowl where it is normally closed by a plug or other
closer, the portion of the bore through the pipe stem being formed as a nozzle that
terminates in proximity to the said aperture and is so arranged with reference to
the bore extension as to form a receptacle for nicotine or like matter substantially
as herein described.
2. A tobacco pipe having a bore extending through the stem and base or body
of the bowl to the exterior thereof the portion of the said bore extending through
the pipe stem from about the point where it communicates with the pipe bowl
being of gradually increasing diameter, whilst the other portion of the bore is of
gradually decreasing diameter towards its outer end which is normally closed by a
plug or other closure, substantially as herein described for the purposes specified.
3. Tobacco pipes constructed and operating substantially as described and
shown in the drawings.
