I WILLIAM ROBERT YATES of 106 Pentonville Road, London, Pianoforte
Manufacturer, do hereby declare the nature of this invention to be as follows :―
This invention relates to an improved construction of tobacco pipe, and is
intended to provide a simple and inexpensive means by which nicotine may be
prevented from reaching the smoker's mouth, or saliva from passing to the
tobacco.
In carrying out my invention the stem of the pipe is formed with a large bore
opening to the bowl through a short passage of small diameter. The mouth piece
is also formed with a cavity of similar size for part of its length, terminating in an
ordinary bore. The stem and mouth piece are formed with an internal screw
thread at their ends, by means of which they are fitted to a central box or chamber
which connects the parts together. This box is screw threaded at the centre, to
permit of it being secured to the stem and mouth piece, and is provided with n
small aperture at each end. The smoke is drawn through the large bore of the
stem into the chamber through the small perforation, and passes out through the
perforation at the other end into the large passage in the mouth piece, and thence
to the mouth. The nicotine is deposited in the stem and chamber, and the saliva
retained in the cavity of the mouth piece, being thereby prevented from passing
along the pipe.
The chamber may be of conical form at one or both ends, the perforations being
at the points, or it may be cylindrical having flat ends, retaining any saliva or
nicotine which may penetrate into it. With this arrangement the smoke is
drawn directly through the bore of the pipe, depositing on its way any nicotine
it may have carried from the tobacco, and the pipe can be easily cleaned when
required.
Dated this 13th day of December 1894.

I, WILLIAM ROBERT YATES of 106, Pentonville Road, London, Pianoforte
Manufacturer, do hereby declare the nature of this invention, and in what manner
the same is to be performed to be particularly described in and by the following
statement :-

This invention relates to an improved construction of tobacco pipe, and is
intended to provide a simple and inexpensive means by which nicotine may be
prevented from reaching the. smoker's mouth,. or saliva from passing to the
tobacco.
In carrying out my invention, the stem of the pipe is formed with a large bore,
opening to the bowl through a short passage of small diameter. The mouthpiece

page_text: is also formed with a cavity of similar size for part of its length, terminating in an
ordinary bore. The stem and mouthpiece are formed with an internal screw
thread at their ends, by means of which they are fitted to a central chamber or
hollow connecting piece. This box is screw threaded at the centre, to permit of it
being secured to the stem and mouthpiece, and is provided with a small aperture at
each end. The smoke is drawn through the large bore of the stem into the
chamber, through the small perforation, and passes out through the perforation at
the other end into the large passage in the mouthpiece, and thence to the
mouth. The nicotine is deposited in the stem and chamber, and the saliva
retained in the cavity of the mouthpiece, being thereby prevented from passing
along the pipe.
In order that the invention may be more clearly understood, reference is had to
the accompanying sheet of drawings, in which
Fig. 1 is a longitudinal section of a pipe, Figs. 2, 3 & 4 are similar views of part
of the pipe, showing three forms of connecting piece and
Fig. 5 is a cross section of the stem of the pipe.
A, is the stem of the pipe, having the enlarged bore or recess a, forming a
chamber, screw threaded at the extremity a'. The mouthpiece B is provided with
a similar recess, the ordinary bore leading into this cavity. The mouthpiece is
also screw threaded at the extremity b. The connecting piece C shown in Fig. 1
is formed with double conical ends, the central cylindrical part e being screwed
externally to correspond to the stem and mouthpiece. These are screwed on from
each end, and meet, giving the pipe an ordinary appearance.
A silver or other band may be used as a mount if desired, but this is not
necessary.
This connecting piece, as shown in Fig. 2, is formed with the central perforation c¹,
through which the smoke is drawn.
In Fig. 3 this connecting piece is in the form of a hollow case c', of metal or any
other suitable material, and in Fig. 4 a different shape is employed, the extremities,
instead of tapering from the centre to the ends, taper in the opposite direction,'
making shoulders at the central part, which is in the form of a screwed boss.
The extension may be cylindrical if found preferable, and other forms of
connecting piece may also be employed if desired, which serve the same
purpose.
In all the arrangements shown chambers are formed on each side of the
connecting piece, in which the nicotine or moisture is deposited, without danger of
it passing through the passage. The smoke is drawn directly through the bore
and deposits any nicotine it may have carried in the chamber formed at the end of
the connecting piece. On unscrewing the mouthpiece and stem the chambers are
completely open and the pipe can be immediately and thoroughly cleaned, there
being no corners which are liable to get fouled.
Having now particularly described & ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.-
(1) In a tobacco pipe, the combination with a cavity in the stem and mouth-
piece, of a detachable connecting piece, through which the smoke passes, forming,
with the stem and mouthpiece, chambers for retaining moisture, substantially as
and for the purposes specified.
(2) In a tobacco pipe, the combination with a stem and mouthpiece formed with
cavities or recesses, of a detachable connecting piece, through which the smoke
passes, having reduced ends, forming, with the recesses above mentioned, closed
chambers to retain moisture, substantially as described and for the purposes
specified.
(3) In a tobacco pipe, the combination with a stem and mouthpiece having
cavities or recesses screwed at the extremities, of a perforated detachable
connecting piece, screwed at the centre to receive the stem and mouthpiece, and

page_text: formed with tapering ends, substantially as described and shown in Fig. 1 of the
drawings and for the purposes specified.
(4) In a tobacco pipe of the kind described, the combination with a stem and
mouthpiece having recesses, of a connecting chamber constructed substantially as
described and shown in Fig. 3 of the drawings annexed and for the purposes
specified.
