I, WALTER CUSTER CUNNINGHAM, of No. 495, Portland Avenue, St. Paul, in the
County of Ramsey and State of Minnesota, U.S.A., Gentleman, 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 it consists in so constructing the
bowl and stem that they may be divided into two parts for the purpose of clean-
ing, as hereinafter shown and described, and specifically pointed out in the
claims.
This invention relates to tobacco-pipes; and it consists in the construction,
combination, and arrangement of parts, as hereinafter shown and described, and
specifically pointed out in the claims.
In the drawings, Figure 1 is a perspective view of the pipe member having
the screw-threaded cavity, and Fig. 2 is a similar view of the other pipe member
or the one having the screw-threaded projection. Fig. 3 is a side elevation of
one of the pipe members. Fig. 4 is a plan view in section on the line x x of
Fig. 1. Fig. 5 is a bottom plan view of the member shown in Figs. 2 and 3.
The bowl of the pipe is divided into two parts A¹ A2, and the integral stem
thereof is likewise divided into two parts, the division being made vertically
and longitudinally, as shown, so that when separated the tobacco-cavity 61 and
the smoke channel 62 will be exposed throughout their entire lengths, so that
all the parts with which the tobacco and the products of the combustion come
in contact can be readily cleansed and kept free from the accummulation of nico-
tine and other deleterious substances.
A circular offset e¹ is formed upon the part A', partially encompassing the
half of the tobacco-cavity 61 in the part A¹ and provided with an external screw-
thread and adapted to engage an internal screw-thread in a recess in the part A³,
the recess being indicated at e2 in Figs. 1 and 4, the recess partially encompassing
the half of the tobacco-cavity b₁ in the part A2. By this simple arrangement,
as before stated, every part of the tobacco-cavity b¹ and the whole length of the
smoke channel 6ª is exposed when the two parts A' A² are separated, so that all
the parts with which the tobacco or the products of the combustion come in
contact can be thoroughly cleansed and kept free from the accumulation of
nicotine or other deleterious matter. Then by the means of the coaction of the
screw-threaded recess in the part A2 and the screw threaded lug on the part A¹
the two parts are firmly united and held rigidly in contact, while the ferrule
clamps the stem-sections together and prevents displacement when not in use.
By thus securing the two parts together no separation along the line of the
union between the two parts can take place, but the joint will be maintained
at all times in a smoke and nicotine tight condition. This forms a very simple
and effective means for fastening the two parts A¹ A together, the juncture
being completed and rendered more effective by the tapered ferrule D₁ of the
mouthpiece, as shown, which when in place firmly binds the two parts of the
stem together.
