COMPLETE SPECIFICATION.
Improvements in and connected with Tobacco Pipes.
I, CHARLES W. FOSTER, of 372 Pacific Street, in the City of Brooklyn,
County of Kings, and State of New York, United States of America, Inventor, 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
Specification:-
This invention relates to pipes, and the object thereof is to provide an improve-
ment in this class of devices, which consists in providing a removable cup or
bottom for the bowl and a removable central tube for the stem, which is connected
with and detachable from the removable cup at one end and at the other with the
mouth piece.
The invention is fully disclosed in the following Specification, of which the
accompanying drawing forms a part, in which :-
Fig. 1, is a central longitudinal section of my improved pipe and the stein
thereof.
Fig. 2, a view of the central tube; and
Fig. 3, a transverse section on the line 3-3 of Fig. 1, said section being on an
enlarged scale.
In the practice of my invention, I provide a pipe comprising the usual bowl A,
and the stem B, which is slightly larger in cross section than in ordinary pipes.
The bowl A, is provided with a removable cup shaped botton piece C, on the
bottom of which is formed an extension D, which projects downwardly at the end
of the longitudinal bore of the stem and connected therewith is a tube E, which
extends through the central bore of the stem, and with the outer end of which the
mouth piece F, is connected.
The tube E, is connected with the cup C, or the extension D, thereof, by means
of screw threads and the mouth picce F, may also be connected with the outer end
of said tube in the same manner.
The tube E is formed of two equal pieces, which when united form a tube and
between the screw threaded ends thereof one of said pieces is provided with
longitudinal flanges G, and the other with longitudinal flanges at each side which
are yoke or U-shaped in cross section and which are adapted to receive the
flanges X G, of the other piece, as will be readily understood; and it will be seen
that by reason of the construction, the annular chamber which surrounds the
tube E, in the stem B, is divided longitudinally.
The operation will be readily understood from the foregoing description when
taken in connection with the accompanying drawing.
By reason of said construction, the mouth piece F may be readily detached from
the tube E, and the tube E, from the cup C, and said parts may be removed from
the stem B, and the bowl respectively, and thoroughly cleaned and again placed in
position whenever desired.
It will also be seen that by reason of this construction the stem B, remains clean
at all times and by reason of the annular chamber between said stem and the
tube E, the stem will not become heated, and by reason of the fact that the tube E
is composed of two parts, said tube may be easily and thoroughly cleaned by simply
separating the parts thereof.

page_text: 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. In a pipe, the combination with the bowl, and stem, of a removable cup in
the bottom of the bowl provided with a downwardly directed extension, a tube
which extends through the stem, and communicates with said extension, and
a mouth piece connected with said tube and stem, substantially as shown and
described.
2. In a pipe, the combination with the bowl and stem, of a removable cup in the
bottom of the bowl provided with a downwardly directed extension, a tube which
extends through the stem and communicates with said extension, and a mouth
piece connected with said tube and stem, said tube being surrounded by an annular
chamber, substantially as shown and described.
3. In a pipe, the combination with the bowl and stem, of a removable cup in the
bottom of the bowl provided with a downwardly directed extension, a tube which
extends through the stem and communicates with said extension, and a mouth piece
connected with said tube and stem, said tube being surrounded by an annular
chamber, and said tube being divided longitudinally, or composed of two separate
parts, substantially as shown and described.
Dated this 17th day of November 1895.
