COMPLETE SPECIFICATION.
Improvements in Tobacco Pipes.
We, WILLIAM TWEEDALE, of Ashton Road, East, Failsworth, Moulder, ABNER HILL,
of Huddersfield Road, Waterhead, Boot Manufacturer, and JOHN WILLIAM LAPISH,
of Walshaw Place, Mumps, Core Maker, all in the County of Lancaster, 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 improvements which are the subject of this invention, relate to tobacco pipes,
and the object of this invention is to provide a convenient and ready means for
cleansing the stem of the pipe either from the nicotine of the tobacco, or from the
saliva or moisture from the mouth which may collect therein: In order more clearly
to describe this our invention, we have annexed hereunto a sheet of drawings: In the
several views therein shown, similar letters refer to similar parts: Fig. 1 represents
a side view, and Fig. 2 a section of a pipe with a straight stem: Fig. 3 is side view,
and Fig. 4 a section of a pipe with a curved stem.
To either of these or similar forms of stems of pipes this invention may be applied :
In this invention we form a pipe in which the lower part a¹ of the bore a in the stem b,
is of smaller diameter than the middle and upper part: We form this lower and
smaller part a' which communicates with bottom of bowl d, of any convenient length:
We insert within the bore a¹ a tube e, of small diameter, which projects into the
stem 6 any preferred length this tube is placed so as to be free from contact with
inner part of said stem: a space is thus formed between the inner part of stem b
and outer part of tube e: We form the stem 6 with any preferred shape of mouth-
piece 9, and this mouthpiece may either be screwed into stem 6 as shown, or held by
being pressed tightly on to end of stem: By these means the space f forms a receptacle
for the saliva from the mouth, and the nicotine or other impurities from the tobacco,
and in order to clear out or empty said space, it is only necessary to draw off or
unscrew the mouthpiece g, and either eject or wipe out the contents of space f.
The projection h which is formed by end of mouthpiece effectually prevents any
impurities entering the mouth, and the noncontact of the end e¹ of tube e with stem ₺,
prevents moisture from the mouth entering the bowl of the pipe: Fig. 5 is side view
and Fig. 6 section showing means for applying this our invention to ordinary forms
of pipes: In these views the tube c is inserted in a plug j formed of any suitable
material which is fitted into the lower part of stem as shown in Fig. 7.
Having now particularly described and ascertained the nature of this our said
invention and in what manner the same is to be performed we declare that what
we claim is.
1st. In a tobacco pipe which is formed in the ordinary manner with either a straight
or a curved stem, the use of a tube which is inserted into the lower part of stem, and
forming a communication with bottom part of bowl of pipe, in order to form a space
between the outside of said tube and the inner part of stem for the collection of
moisture and impurities in the manner substantially as herein before described.
2nd. In a tobacco pipe the use of a tube fitted in a plug of wood or other material,
in order that the same may be inserted in existing forms of pipes as shown in Fig. 7
on drawings for the purpose and in the manner substantially as herein before
described.
