Improvements in Tobacco Pipes.
I, CHARLES ARTHUR ALLISON, of 52 Chancery Lane, London, in the County
of Middlesex, Patent Agent, do hereby declare the nature of this invention (which
has been communicated to me from abroad by Samuel Dimmick Mott, of Passaic,
New Jersey, United States of America, Electrical Engineer) to be as follows:-
:-
The said invention relates especially to tobacco pipes the bowls of which are
made separate from the stem, and the construction of the parts is such that a pipe
is easily cleaned, its durability is greatly increased, its parts are readily renewed,
the bowl is reversible, the danger of spilling lighted tobacco is avoided, the
connection between the stem and mouthpiece is strengthened, and a convenient
surface for lighting matches is provided.
In the drawing

bowl. This figure also shows a preferable shape to give the article, and a place on
its surface that may be made rough for lighting matches.
Figure 2 is a sectional view through the bowl and stem of a pipe.

Like numerals indicate corresponding parts in all the figures.
1 is the stem of the pipe and 2 the mouthpiece. At 3 the stem is broadened,
made flat and arranged to receive the bowl 4. 5 is the smoke passage through the
stem and mouthpiece. Though the bowl may be formed in other shapes, it is here
shown as cylindrical, open at both ends, and is provided with annular off-sets.
These off-sets are made to fit snugly into the enlargement 3, thus holding the bowl
securely in connection with the stem. In Figs. 1, 2, and 4 the bowl is shown as
having lugs 8 arranged to enter grooves in the part 3 of the pipe as indicated by
dotted lines in Figures 3 and 4, when by turning said bowl to the right, it will be
locked upon the stem. In the modification shown in Figure 5 the bowl screws into
the stem portion of the pipe. In Figures 2 and 5 a small bead is shown encompassing
the bowl. This is to relieve the plainness of the bowl and to make any slight
shrinkage of the bowl when first used unnoticeable.
9 Figure 2 shows the method of strengthening the weakest part of the stem, and
consists in forming the stem conical in shape and fashioning the mouthpiece to
receive the same. The apex of the cone is projected cylindrically and may be
screw-threaded or smooth; in the one case the mouthpiece is turned to its proper
position, and in the other it is simply inserted, being held in place by frictional
adherence. It is evident that the construction may be reserved and the mouthpiece
be inserted into the stem, but the way shown is preferable, because the mouthpiece
when separated can be conveniently used as a cigar holder. 10 Fig. 1 shows a
countersunk portion of the stem which may be roughened by any suitable means
for the purpose of lighting matches.
When constructed and arranged in accordance with the foregoing description,
this improved pipe will be found to possess many desirable features and advantages;
when the tobacco is lighted and partially smoked in the usual manner the bowl may

page_text: be reversed in position upon the stem, thus causing the tobacco to burn upward
instead of downward. This will prevent the accumulation of the disagreeable
residue in the bowl, preserving the freshness of the tobacco until it is all consumed,
when the ashes may be emptied in the usual manner. The pipe may be used as an
ordinary pipe but reversing the bowl practically doubles the time it will last and
makes it self-cleaning. The bowl and stem not being integral the two parts may
be largely made of scrap material, thus making a considerable saving to the
manufacturer, and any worn out portion of the pipe may be renewed. The flat
bottom supporting the bowl prevents the tobacco from packing, and when the bowl
and stem are separated the stem may be easily cleaned as a straight passage is
opened through it and any substance lodged therein may be readily removed.

COMPLETE SPECIFICATION.
Improvements in Tobacco Pipes.
I, CHARLES ARTHUR ALLISON, of No. 52 Chancery Lane, London, in the
County of Middlesex, Patent Agent, do hereby declare the nature of this invention
(which has been communicated to me from abroad by Samuel Dimmick Mott, of
Passaic, New Jersey, United States of America, Electrical Engineer), and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The said invention relates especially to tobacco pipes the bowls of which are
made separate from the stem, and the construction of the parts is such that a
pipe is easily cleaned, its durability is greatly increased, its parts are readily
renewed, the bowl is reversible, the danger of spilling lighted tobacco is avoided,
the connection between the stem and mouthpiece is strengthened, and a convenient
surface for lighting matches is provided.
Referring to the drawing accompanying the Provisional Specification,
Figure 1 is a side elevation of the pipe contained in a case showing an extra
bowl. This figure also shows a preferable shape to give the article, and a place on
its surface that may be made rough for lighting matches.
Figure 2 is a sectional view through the bowl and stem of a pipe.
Figure 3 is a plan view of the stem with the bowl removed, and Figure 4 is a
plan view of one end of the bowl. Figures 3 and 4 show the preferable method of
fastening the bowl and stem together, by the bayonet joint arrangement.
Figure 5 is a side view of a bowl, showing a modified method of fastening by a
screw thread which engages with the stem portion of the pipe.
Figure 6 is an end view of the stem showing its shape and position when placed
upon a level surface, which position prevents the spilling of its contents.
Like numerals indicate corresponding parts in all the figures.
1 is the stem of the pipe and 2 the mouthpiece. At 3 the stem is broadened,
made flat and arranged to receive the bowl 4. 5 is the smoke passage through the
stem and mouthpiece. Though the bowl may be formed in other shapes, it is here
shown as cylindrical, open at both ends, and is provided with annular off-sets.
These off-sets are made to fit snugly into the enlargement 3, thus holding the bowl
securely in connection with the stem. In Figs. 1, 2 and 4, the bowl is shown as
having lugs & arranged to enter grooves in the part 3 of the pipe as indicated by
dotted lines in Figures 3 and 4, when by turning said bowl to the right, it will be
locked upon the stem. In the modification shown in Figure 5 the bowl screws into
the stem portion of the pipe. In Figures 2 and 5 a small bead is shown
encompassing the bowl. This is to relieve the plainness of the bowl and to make
any slight shrinkage of the bowl when first used unnoticeable.

page_text: 9, Figure 2, shows the method of strengthening the weakest part of the stem,
and consists in forming the stem conical in shape and fashioning the mouthpiece
to receive the same. The apex of the cone is projected cylindrically and may
be screw-threaded or smooth; in the one case the mouthpiece is turned to its
proper position, and in the other it is simply inserted, being held in place by
frictional adherence. It is evident that the construction may be reversed and
the mouthpiece be inserted into the stem, but the way shown is preferable, because
the mouthpiece when separated can be conveniently used as a cigar holder.
10, Fig. 1, shows a countersunk portion of the stem which may be roughened by
any suitable means for the purpose of lighting matches.
When constructed and arranged in accordance with the foregoing description,
this improved pipe will be found to possess many desirable features and advan-
tages; when the tobacco is lighted and partially smoked in the usual manner
the bowl may be reversed in position upon the stem, thus causing the tobacco to
burn upward instead of downward. This will prevent the accumulation of the
disagreeable residue in the bowl, preserving the freshness of the tobacco until
it is all consumed, when the ashes may be emptied in the usual manner. The
pipe may be used as an ordinary pipe, but reversing the bowl practically doubles
the time it will last and makes it self-cleaning. The bowl and stem not being
integral the two parts may be largely made of scrap material, thus making a
considerable saving to the manufacturer, and any worn out portion of the pipe
may be renewed.
The flat bottom supporting the bowl prevents the tobacco
from packing, and when the bowl and stem are separated, the stem may be easily
cleaned, as a straight passage is opened through it, and any substance lodged
therein may be readily removed.
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 :-
1. In a tobacco pipe a reversible bowl formned substantially as herein shown and
described.
2. In tobacco pipes a seat formed on the end of the stem constructed to receive
and hold the bowl in place, substantially as herein shown and described.
3. In a tobacco pipe, the combination of a reversible bowl and a stem enlarged
at one end, for the purpose and substantially as herein shown and described.
4. In a tobacco pipe, provided with a reversible bowl, a straight passage through
the stem of the pipe and seat of the bowl, which when the bowl is removed
becomes an unobstructed passage, for the purpose and substantially as herein
shown and described.
5. A tobacco pipe with a reversible bowl provided with a flat bottom for the
purpose and substantially as herein shown and described.
6. A tobacco pipe provided with a mouthpiece, and stem, the two parts being
formed and joined together substantially as herein shown and described.
7. A. tobacco pipe provided with a roughened surface on an exposed part for the
purpose and substantially as herein shown and described.
8. The combination in a tobacco pipe of a reversible bowl, a stem provided with
a bowl seat, and a mouth-piece, the parts being constructed and united together
substantially as herein shown and described.
