Improvements in Smoking-pipes.
A communication from abroad by LARSENS PIBEFORRETNING, of Lillehammer,
in the Kingdom of Norway.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both
in the County of Lancaster, and 323, High Holborn, in the County of Middlesex,
Civil 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 :-
This invention relates to an arrangement of smoking pipes, whereby oil and other.
substances collecting in the channel may be removed very easily.
According to this invention the channel of the pipe-stem is prolonged underneath
the tobacco bowl beyond the point where this latter communicates with the
channel and in this extension of the channel is placed a piece of leather, rubber or
other suitable material, which is fixed on the end of a rod passing along through
the channel such a distance that, when the mouthpiece or other upper part of the
pipe is taken off, it may be grasped by the fingers and drawn out, thereby cleaning
the channel, the said piece of soft or flexible material acting as a piston.
In the accompanying drawing is shown one way in which the said invention may
be practically employed for a short pipe. In this e is the tobacco bowl communi-
cating with the channel g of the stem, through the holes f. The channel g is
prolonged beyond the holes whereby a pocket is formed, in which a disc c of
leather, rubber, felt or similar material fits, the disc being fixed on the end of the
rod d passing up through the channel and projecting into the bore of the mouth-
piece. Oil and other substances gathering in the channel.g are easily removed by
drawing the rod d with the disc c out of the channel, the mouthpiece having first
been removed. When the disc c and stem d have been washed and cleansed, they
are again inserted, and the pipe is again ready for use.
The same arrangement may, with, suitable modifications, be employed for any
kind of pipes.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed as communicated to me
by my foreign correspondent, I declare that what I claim is :-
1. In a smoking pipe the extension of the channel in the pipe stem underneath
the tobacco bowl and beyond the point where the latter communicates with the
channel, in combination with a disc of soft material, placed near the end of said
extension, and fixed to the end of a rod, by means of which it may be drawn out of
the channel, thereby removing oil and other substances from the same.
2. A smoking pipe having a channel g through its stem, prolonged beyond the
holes fleading to the tobacco bowl and having inserted in the pocket, thus formed,
a disc c of leather, rubber, felt or similar material fixed on the end of a stem d
passing up through the channel of the pipe, substantially as described.
