IMPROVEMENTS IN TOBACCO PIPES.
Year: 1882

page_text: PROVISIONAL SPECIFICATION left by the said John Stanley at the Office
of the Commissioners of Patents on the 19th May 1882.
JOHN STANLEY of Manchester in the County of Lancaster, "IMPROVEMENTS IN
TOBACCO PIPES.
"
My invention relates to the smoke passages in tobacco pipes, my object being to
produce a pipe that will cool the smoke and condense a large amount of nicotine
and that may be very easily cleaned.
I accomplish this in the following manner:-I bore a hole through the stem of
the pipe, large enough to admit of a separate piece being inserted into it, which
may be withdrawn when required for cleaning, Upon this movable piece I form
the smoke passage, in the form of a groove or grooves of helical or other suitable
form, varying the length and amount of surface in the smoke passage, so as to
produce a mild, medium or strong flavoured pipe.
The smoke passage may be all formed on the movable piece or partly on it, and
partly in the hole in the stem, or the whole of it may be formed in the stem in the
latter case the movable piece would be plain; or the passage may be formed on the
outside of the stem and covered with a suitable material.
By applying my invention to a pipe with an ordinary short stem a very long
smoke passage may be obtained.

I bore a hole in the stem of the pipe large enough to admit of a separate piece
being inserted into it which may be withdrawn when required for cleaning; upon
this movable piece I form the smoke passage in the form of a groove or grooves of
helical twist or other suitable form varying the length and amount of surface in
the smoke passage so as to produce a mild, medium or strong flavoured pipe. The
movable piece may be made in one or more pieces, or may be made hollow with a
groove or grooves inside of it in addition to those outside.
The smoke passage may be all formed on the movable piece or partly on it and
partly in the hole in the stem, or the whole of it may be formed in the stem, in the
latter case the movable piece would be plain or the passage may be formed on the
outside of the stem and covered with a suitable material.
By applying my invention to a pipe with an ordinary short stem a very long
smoke passage is obtained.
And in order that my invention may be fully understood and readily carried
into effect I will describe the accompanying sheet of drawings reference being had
to the figures and letters marked thereon.
Fig. 1 shows in section a pipe to which my invention is applied. Fig. 2 shows
part of the same. Fig. 3 shows the movable piece in or on which a helical groove
or thread is formed and provided with an enlarged space c for the nicotine or other
matter to settle in varying the size, form and number of grooves or threads in
producing a mild, medium and strong flavoured pipe.
I use fine or small grooves or threads in making a mild pipe and larger ones for
a medium pipe and two or more grooves or twists in strong flavoured pipes
Fig. 4 shows a two grooved movable piece, the smoke passage being of helical or
twist form and Fig. 5 shows in section another form of pipe to which my invention
is applied.
On the movable piece a is formed a left hand screw on which the mouthpiece b
is secured this is to prevent the mouthpiece from being unscrewed when the
piece A is turned round (as is sometimes necessary) to withdraw it from the stem
of the pipe a hole is made at the end of the piece A. to allow the helical groove
which forms the smoke passage to communicate with the hole in the mouthpiece b.
The pipe may be made of wood or other material and the movable piece may be
made of bone, earthenware, metal or other suitable material.
Having stated the nature of my invention and described the manner of performing
the same. I would have it understood that I do not limit myself to the details
given as they may be varied or modified and
I declare that I claim
The improvement in tobacco pipes whereby I am enabled to obtain a long smoke
passage with a short stem substantially as shown and described.
In witness whereof I the said John Stanley have hereunto set my hand and
seal this twenty-third day of November, One thousand eight hundred and
eighty tive
