Improvements in Tobacco Pipes.
I, CHARLES HENRY MOLYNEUX, residing at 120 Barrington Street, Halifax, in the
Province of Nova Scotia, and Dominion of Canada, Motorman, 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 relates to tobacco pipes, and the object thereof, is to provide an
improved device of this class which is so constructed that nicotine or fluids saturated
with nicotine cannot flow through the mouth piece of the stem, into the mouth, a
further object being to provide a pipe stem which is provided with a longitudinal
tube which is packed with asbestos wool, or similar material so as to break up and
retard the flow of the smoke therethrough, and to cool the same, said packing also
serving to prevent, dust and other substances from passing through the stem, and with
these and other objects in view, the invention consists in the construction,
combination and arrangement of parts hereinafter described and claimed.
The invention is fully disclosed in the following specification, of which the
accompanying drawing forms a part, in which the separate parts of my improvement
are designated by numerals of reference in each of the views, and in which :-
Fig. 1, is a central vertical longitudinal section of my improved pipe; and,
Fig. 2, a cross section of the stem thereof, taken on the line 2, 2 of Fig. 1.
In the practice of my invention, I provide a tobacco pipe; having the usual
bowl 5, provided with a stem 6, which is provided with the usual longitudinal hore 7,
which is enlarged for almost its entire length, so as to receive a tube 8, which is
inserted from the outer end, and which is filled with a packing 9, composed of
mineral or asbestos wool or similar material, and the tube 8, is held in place by a
screw threaded coupling piece 10, which is connected with the outer end of the stein,
and which is provided centrally thereof, with an inwardly directed annular shoulder
or projection 11.
The mouth piece 12, is connected with the coupling piece 10, preferably by means
of a screw threaded extension as shown at 13, and said mouth piece 12, is also
provided with an upwardly directed or curved end extension 14, by means of which
Huids and other substances are prevented from flowing outwardly through said
mouth piece, and the end of the mouth piece is provided on its under side with a
concave portion 15, and on its upper side with a corresponding concave portion 16,
by which it may be better held in the month and from its shape, take up but little
space therein.
Formed in the bottom of the stem 6, and longitudinally thereof, is a groove 17,
which extends the full length of said stem and backwardly to the bottom of the
bowl, and which communicates with a narrow port or passage 18, in the inwardly
directed annular shoulder or projection 11, of the coupling piece 10, and this port or
passage forms a communication between said groove 17, and the mouth piece, and
said groove is closed by a longitudinal slide 19, which is connected with the stem by
a tongue and groove joint as shown at 20, in Fig. 1, and the rear end of said slide
is provided with a depending tubular receptacle 21, and the mouth piece 21, is
connected with the coupling piece 10, by means of an enlarged head 22, which is
cylindrical in cross section, and in practice, the saliva and other fluids collect in this
enlarged head of the mouth piece and flow backwardly through the groove 17, and
into the receptacle 21, and may be removed therefrom, by removing the slide 19.

page_text: It will be apparent that the separate parts of the stem or the mouth piece 12, the
coupling piece 10, and the tube 8, may be disconnected whenever desired, and all of
said parts cleaned and again connected, and it will thus be seen that I accomplisb
the object of my invention, by means of a device which is simple in construction and
operation, and which is well adapted to produce the result for which it is intended.
The slide 19, only extends forwardly to the point indicated at 23, and said slide
may be removed, and cleaned whenever desired without reference to the other parts.
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 :-
-
1. The herein described pipe, which comprises a bowl, a stem provided with a
central bore which communicates therewith, the outer portion of said bowl being
enlarged and provided with a detachable tube, which is filled with mineral wool or
similar material and said stein being provided with a mouth piece which is connected
there with by a collar by which the tube is held in place, substantially as shown and
described.
2. The herein described pipe, which comprises a bowl, a stem provided with a
central bore which communicates therewith, the outer portion of said bowl being
enlarged, and provided with a detachable tube, which is filled with mineral wool or
similar material, and said stem being provided with a mouth piece which is connected
therewith by a collar by which the tube is held in place, said mouth piece being
upwardly curved at its outer end, substantially as shown and described.
3. The herein described pipe, which comprises a bowl, a stem provided with a
central bore which communicates therewith, the outer portion of said bowl being
enlarged, and provided with a detachable tube which is filled with mineral wool or
similar substances, and said stem being provided with a mouth piece which is co-
nected therewith by a collar, by which the tube is held in place, said stem being
upwardly curved at its outer end, and the said mouth piece being also provided with
a longitudinal groove in the bottom thereof, which communicates with the mouth
piece, and which is closed by a longitudinally movable slide at the rear end of
which is a depending receptacle, substantially as shown and described.
4. A mouth piece for the stems of pipes, the outer end of which is curved
upwardly, substantially as shown and described.
Dated this 4th day of March 1897.
