PROVISIONAL SPECIFICATION.
Improvements in and relating to Tobacco Pipes.
I WALLACE RITCHIE 6 Wood Street Liverpool Merchant, do hereby declare-
the nature of this invention to be as follows:
The invention consists of an outer pipe made of briar-wood, meerschaum or other.
material, and an inner pipe made of clay, wood, or other material. The inner pipe
is formed of two pieces, namely a bowl and a stem. When in use the bowl of the
inner pipe is placed inside the bowl of the outer pipe, and the stem of the inner
pipe is placed inside the stem of the outer pipe. A mouthpiece made of vulcanite,
amber or other material is added to make the pipe complete. My object is to
supply a complete inner pipe which can be renewed when foul & replaced at slight
cost by a fresh one. A washer or band of cork or other material is used to connect
the bowl & stem of the inner pipe to prevent leakage, and a washer or band
formed of rubber or other material is used to connect the stem of the inner pipe.
with the mouthpiece or stem of the outer pipe to prevent leakage. The great
advantage of this over other pipes where an inner pipe is used is that the outer-
pipe is not required to be split or divided.
Dated this First day of April 1895.

Improvements in and relating to Tobacco Pipes.
I WALLACE RITCHIE 6 Wood Street Liverpool Merchant 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 invention consists of an outer pipe made of briar-wood meerschaum or other-
material and an inner pipe made of clay, wood or other material. The inner pipe.
is formed of two pieces, namely a bowl and a stem. When in use the bowl of the
inner pipe is placed inside the bowl of the outer pipe, and the stem of the inner pipe
is placed inside the stem of the outer pipe. A mouthpiece made of vulcanite, amber
or other material is added to make the pipe complete. My object is to supply a
complete inner pipe which can be removed when foul and replaced at slight cost by
a clean one. A washer or band made of cork, india rubber or other material is used
to connect the bowl and stem of the inner pipe to prevent leakage, and a further
band of india rubber or other material is used to connect the stem of the inner pipe
with the mouthpiece or stem of the outer pipe to prevent leakage. The great.
advantage of this over other pipes where an inner pipe is used is that the outer-
pipe is not required to be split or divided, but can be made in one piece.

pipe, F the band used to connect the stem of the inner pipe with the mouthpiece,
and B B the mouthpiece.
I have only given drawings of one shape of pipe to which these improvements
can be applied, but it is obvious that the same principle can also be applied to pipes
of other shapes.
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 :
1. A double or duplex pipe, the inner portion of which consists of a bowl and
stem complete and formed in two pieces, the outer portion of the pipe being in one
piece, exclusive of the mouthpiece and metal band.
Dated this Thirty-first day of December 1895.
