PROVISIONAL SPECIFICATION.
Improvements in Tobacco Pipes and Oigar or Cigarette Tubes.
I, RICHARD BRADSHAW, of Bridge Road, Edge Hill, Liverpool, in the County
of Lancaster, Mechanical Engineer, do hereby declare the nature of this invention
to be as follows:-
The object of this invention is to construct a tobacco pipe or holder for cigars
or cigarettes through which the smoke will be cooled in its passage to the mouth
of the smoker.
.
It consists essentially in providing ventilating apertures in the stem or tube
whereby air may be admitted to mingle with the smoke as it passes through and
if desired a protective cover or valve to regulate the admission of air.
In carrying out the invention I perforate the stem or tube with one or more
apertures or perforations in any convenient position preferably near the
mouthpiece.
For pipes or cigar holders the aperture or apertures may be placed in a small
tube branching out therefrom or may be in the ferrule by which the mouthpiece is
joined to the stem. In this latter case a second ferrule or other sliding appliance
may be fitted over the perforations to open or close them as desired or any other
suitable form of valve may be employed such as a bellows valve or the like which
will admit a small amount of air and prevent escape of smoke.
For cigarette holders of paper or other light material such as are supplied with
packets of cigarettes a number of sunall perforations in annular or other form may
be employed. For other cigarette tubes such as wood or meerschaum the holes
may be covered or protected as above described for cigar holders.

I, RICHARD BRADSHAW, of Bridge Road, Edge Hill, Liverpool, in the County
of Lancaster, Mechanical Engineer, 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 :-
The object of this invention is to construct a tobacco pipe or holder for cigars or
cigarettes through which the smoke will be cooled in its passage to the mouth of
the smoker.
I find that by admitting a small quantity of. cool air into the stem of the pipe it
greatly cools the smoke condensing therefrom a portion of the moisture and allows
the smoke to expand.
It consists essentially in providing ventilating apertures in the stem or tube
whereby air may be admitted to mingle with the smoke as it passes through and
a protective cover or valve to regulate the admission of air.

page_text: The invention will be fully described with reference to the accompanying
drawings.

Fig. 2. Longitudinal section of same.
Fig. 3. Transverse section on line -y Fig. 2 (enlarged scale).
Fig. 4. Extended plan of the band or ring E.
Fig. 5. Longitudinal section of cigar tube.
Fig. 6. Longitudinal section of cigarette tube.
Fig. 7. Longitudinal section of modified arrangement of cigar tube.
Fig. 8. Longitudinal section of similar arrangement of cigarette tube.
In carrying out the invention I perforate the stem or tube with one or more
apertures or perforations in any convenient position preferably near the mouthpiece
and I provide a band or ring capable of being moved over the aperture so that the
size or area of the aperture may be regulated or it may be entirely closed.
I prefer to construct the pipe or tube as illustrated in Figs. 1 to 6 in which the
stem or tube A and the mouthpiece B are connected together with a ferrule C
forming a chamber D between the two. The ferrule C is perforated with an
aperture c through which air can be admitted into the chamber D to mingle with
the smoke. Round the ferrule C is placed a band or shutter E with a series of
apertures or perforations e of different sizes any one of which can be placed over
the aperture c in the ferrule C to admit more or less air as desired or the band or
shutter E can be turned to cover over and close the aperture c.
In Figs. 7 and 8 the aperture is made in the tube A and the ring or band E
placed thereon to cover the aperture.
It is to be understood however that the aperture c may be placed in any other
convenient position to admit air to meet the smoke and mingle with it as it passes
from the tobacco. And any other suitable form of valve or shutter may be
employed such as a bellows valve or the like which will admit a small quantity of
air and prevent escape of smoke or which may be opened and closed as desired.
For cigarette holders of paper or other light material such as are supplied with
packets of cigarettes a number of small perforations in annular or other form may
be employed.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A tobacco pipe, cigar tube or cigarette tube constructed with a small
aperture in the stem to admit a small quantity of air to mingle with the smoke
substantially as and for the purpose described.
2. A tobacco pipe, cigar tube or cigarette tube provided with an aperture or
perforated ferrule through which air is admitted to mingle with the smoke in
combination with a perforated shutter to regulate or close the aperture
substantially as described.
3. A. tobacco pipe, cigar tube or cigarette tube constructed substantially as
described and shown.
