Improvements in Tobacco Pipes.
I, PIERE JEAN DÉSIRÉ TOSSENS, of Moulan, near Liége, in the Kingdom of
Belgium, Miller, do hereby declare the nature of this invention to be as fol-
lows:
In ordinary tobacco pipes, the cleansing of the bore of the stem is always a
difficulty and frequently cannot be accomplished without the aid of a brush,
feather or the like.
The object of this invention is to remedy this inconvenience, by employing
inside the bore or stem of the pipe, a tube longitudinally divided into two parts.
The invention is represented in the accompanying drawing in its application
to two kinds of pipe.
Figure 31
Figures 1 and 2 are longitudinal sections of the pipes, whilst Figures 3 to 5
are transverse sections of the internal tube upon an enlarged scale.
shows the halves with plan and Figures 4 and 5 with grooved faces.
The internal tube a may be made of wood, earthenware, ebonite, glass, metal
or the like, and may be made of the same diameter throughout its length but is
preferably reduced at the two extremities in order that the coned ends may be
easily adjusted into the conical parts c, c¹, of the bore of the pipe stem, .but the
front end may be of such a diameter as not to extend into the perforation in
the mouthpiece.
The tube a, is made of two superimposed pieces, having between them the
passage for the smoke. These two parts may be kept together either by their
ends fitting into coned parts in the bore of the pipe stem, as previously described,
or by a band of metal or the like, as in Figure 1, or by a ferrule or stopper d,
as in Figure 2, or further, or the internal pipe may be enveloped in a sheath
of rubber or other flexible material. In Figure 2, the stopper or ring d may
serve to maintain the internal pipe a, within the bore of the pipe stem b, and
prevent the displacement of the former within the latter. The internal tube
may also be applied to pipes having curved stems.
By means of this internal pipe, the smoke does not pass at all into the bore
of the stem, and consequently, the latter does not become foul, or only slightly
50. To cleanse the tube a it is withdrawn from the pipe stem and after remov-
ing the ring d, or the covering sheath of rubber (when one is employed), the
two parts of the pipe may be separated, and the smoke passage cut longitudinally
up the said parts is thus exposed and may be cleansed with great facility.

in and by the following statement:-
In ordinary tobacco pipes, the cleansing of the bore of the stem is always a
difficulty and frequently cannot be accomplished without the aid of a brush,
feather or the like.
The object of this invention is to remedy this inconvenience, by employing
inside the bore or stem of the pipe a tube longitudinally divided into two parts.
The invention is represented in the drawing filed with the Provisional Specifica-
tion in its application to two kinds of pipe.

shows the halves with plain, and Figures 4 and 5 with grooved faces.
The internal tube a may be made of wood, earthenware, ebonite, glass, metal
or the like, and may be made of the same diameter throughout its length but is
preferably reduced at the two extremities in order that the coned ends may be
easily adjusted into the conical parts c, c', of the bore of the pipe stem, but the
front end may be of such a diameter as not to extend into the perforation in
the mouthpiece.
The tube a, is made of two superimposed pieces, having between them the
passage for the smoke. These two parts may be kept together either by their
ends fitting into coned parts in the bore of the pipe stem, as previously described,
or by a band of metal or the like d, as in Figure 1, or by a ferrule or stopper d,
as in Figure 2, or the internal pipe may be enveloped in a sheath
of rubber or other flexible material. In Figure 2, the stopper or ring d, may
serve to maintain the internal pipe a, within the bore of the pipe stem b, and
prevent the displacement of the former within the latter. The internal tube
may also be applied to pipes having curved stems.
By means of this internal pipe the smoke is prevented from passing at all into the
bore of the stem, and consequently, the latter does not become foul, or only slightly
80. To cleanse the tube a it is withdrawn from the pipe stem and after remov-
ing the ring d, or the covering sheath of rubber (when one is employed), the
two parts of the pipe may be separated, and the smoke passage cut longitudinally
up the said parts is thus exposed and may be cleansed with great facility.
The internally located and removable pipe or tube may be made from any
suitable material, such as wood, earthenware, glass, ebonite or metal, and if
necessary may be made in three or more separable longitudinal segments secured
together when in use by means such as herein before referred to.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
In tobacco pipes, the employment within the stem, of a removable tube or
pipe, through the passage of which the smoke is drawn, and made up of two or
more assembled longitudinal sections, which, when removed from the pipe and
separated, lays bare the smoke passage for cleansing, substantially as herein
described and also as set forth in the accompanying drawings.
