Improvements in and relating to Tobacco-pipes.
I, WARREN EDWARD TROTT, of No. 1198, Bedford Avenue, in the City of
Brooklyn, United States of America, Mercbant, do hereby declare the nature of
this invention and in what manuer the same is to be performed to be particularly.
described and ascertained in and' by the following statement :-
This invention relates to that class of tobacco-pipes wherein means are provided
for facilitating the cleaning of the smoke-passage in the stem, and the object of the
invention is to provide a simple and convenient device for throwing open the smoke-
passage along substantially the entire length of the stem, that is, from the bowl-of-
the pipe to the mouth-piece. To this end, the leading feature of my invention
consists in forming a slot longitudinally along the stem and' opening into the smoke-
passage, and in fitting in this slot a removable closing strip or tenon. Another
feature is a dam carried by the closing strip, the construction and object of which
will be hereinafter set forth.
In the accompanying drawings, which serve to illustrate the invention, I have
showu several modifications, and these drawings I will now proceed to describe..
Fig. 1 is a perspective view of a tobacco-pipe made according to my invention
wherein a sliding closing strip or tenon is fitted into a longitudinal dovetail slot in
the stem.
Fig. 2 is a similar view showing the sliding closing strip or tenon partly with-
drawn.
Fig. 3 is a corresponding view partly in longitudinal section and partly in side
elevation.
Fig. 4 is a transverse section on the line 4 4 in Fig. 3.
Fig. 5 is a view similar to Fig: 3 but illustrating a modification of my invention
wherein the closing strip or tenon does not slide; that strip.or tenon being held' in
place at one end by an inclined portion fitting under the bowl and at the other end
by a removable mouth-piece.
Fig. 6 is a transverse section on the line 6 6 in Fig. 5.
Fig. 7 represents another modification of the invention.
1 is the bowl of the pipe. 2 is the stem provided with a longitudinali slot 3,
which is rabetted, dovetailed or undercut at the sides to receive lateral ribs 4 on
the closing strip or tenon 5. This closing strip 5 is rivetted at one end to the
mouth-piece 6, but this is not at all essential to the invention, for it may be other-
wise secured, and moreover it is obvious that the strip may be formed separately
from and be entirely independent of the mouth-piece. The strip 5 is provided
with a raised overhanging crown 7, having rounded edges, as clearly shown. The
crown is added merely to insure a tight joint between the strip 5 and the side-walls
of the slot 3 in the stem 2. It also adds somewhat to the appearance of the pipe
It is, however, not essential to the invention.
8 is a dam, which is secured to or formed on the under side of the strip 5, and
projects down into the smoke-passage 9 of the stem 2. The form of the dam 8 is
such that its curved under surface closely fits the base of the smoke-passage 9, and
prevents the flow of moisture or liquid from the bowl of the pipe into the smoker's
mouth, while the upperiportion of tlie dam is contracted so as to provide spaces 10 for
the passage of the smoke. This feature is not essential to the invention, and may
be dispensed with.
In the modification shown in Figs. 5 and 6, the groove has outwardly sloping or
converging side-walls, and the strip 5 is provided with correspondingly sloping
sides. In order to insure a tight joint, the strip 5¹ is furnished with a metallio

page_text: lining or covering 11 on its under side. In order to hold the strip 7' in place in
the slot, one end of the latter (the one near the bowl) is undercut, the outer end' of
the strip being held down by slipping the mouth-piece over it. In this construction,
it is not necessary to slide the closing strip longitudinally, but; after removing
the mouth-piece 6, the strip may be lifted out, as indicated in dotted lines in
Fig. 5.
In the modification shown in Fig. 7, the strip is provided with an expanded
upper portion 12 fitting in a recess formed in the upper face of the stem 2.
It is obvious that considerable variation may be made in the form and arrange-
ment of the closing strip in order to suit different styles and forms of pipe, and for
this reason I do not wish to limit myself to any particular design or arrangement.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I claim :-
-
1. A tobacco-pipe having a stem formed with a slot extending longitudinally
and communicating with the smoke-passage, a closing strip or tenon fitting in the
slot, and means for holding the closing strip or tenon in place, substantially as
herein described.
2. A tobacco-pipe having a straight slot extending the entire length of the stem.
and open to the smoke-passage, the slot corresponding in width with that passage,
and a closing strip or tenon fitting in the slot, the closing strip or tenon having
projecting parts which take under overhanging parts on the pipe, substantially as
herein described.
3. A tobacco-pipe having a straight slot extending the entire length of the stem
and open to the smoke-passage, the slot corresponding in width with that passage,
and a sliding or closing strip or tenon with rabetted edges fitting into the side-walls
of the slot, substantially as herein described.
4. The combination, with a tobacco-pipe having a stem formed with a slot
extending longitudinally and opening into the smoke-passage, of a sliding covering
strip with rabetted edges fitting into and closing the slot, and a removable mouth-
piece secured to the covering strip and provided with a band which fits over the
end of the stem and forms a smoke-tight joint,, substantially as herein described.
5.. A tobacco-pipe having a slot in its stem.open to the smoke-passage, a strip or
tenon to close the slot, and a dam carried by the strip or tenon and fitting into the
smoke-passage, the dam being adapted to hold back the liquids and permit the
passage of smoke, substantially as herein described.
