Improvements in Tobacco Pipes and the Means for Cleaning them.
JOHN THRUSH, 24, Crompton Street, Derby, Gentleman, LANCELOT WALTER DE
GRAVE, 11, Charnwood Street, Derby, Engineer, do hereby declare the nature of
this invention to be as follows:-
An improved arrangement for collecting and removing the fouling from the
bowl & stem of pipes or other apparatus (hereafter called the pipe) employed in
the consumption of tobacco or the like by the inhalation & exhalation of the
products of combustion or smoke.
The manner in which this is carried into effect will be ascertained from the
following description.
In the stem of a pipe is placed a tube of metal or other suitable material (here-
after called the tube) preferably cut in the direction of its length either straight
or spirally thus making a C section and forming a removable bore to the pipe.
The tube is made a good fit in the bore of the pipe (varyations in bore being
met by opening or closing the (C section) tube on itself) and preferably passes
right into the bowl of the pipe from the mouthpiece at which end it can be
provided with a knob or head for ease of withdrawing or left flush with or short of
the end and brought into reach for withdrawing by being pushed from the bowl
of the pipe.
When withdrawn the tube can be cleaned in any convenient manner for instance
by inserting a piece of paper in the cut and drawing it the length of the tube
which is then ready for replacing in the pipe.

or spirally thus making a C section & forming a removable bore to the pipe."
This tube is made a good fit in the bore of the pipe (variations in the bore of
pipes being met by the opening or closing of the split tube on itself) & pre-
ferably passes right into the bowl of the pipe from the mouthpiece, at which end
it can be provided with a knob or head, for ease of withdrawing, or left flush
with or short of the end & brought into reach for withdrawing by being pushed
from the bowl of the pipe.
When withdrawn the tube can be cleaned in any convenient manner for instance
by inserting a piece of paper in the cut & drawing it the length of the tube which
is then ready for replacing in the pipe.
Having now particularly described & ascertained the nature of our said invention
& in what manner the same is to be performed, we declare that what we claim
is:―
(1) In connection with tobacco pipes & the like a tube, forming a false bore to
the pipe stem, which can be removed for cleaning.
(In connection with tobacco pipes & the like a tube, which can be removed
from the stem of the pipe for cleaning, split or cut in the direction of its length
either straight or spirally.
(3) In connection with tobacco pipes & the like a tube, which can be removed
from the stem of the pipe, having a head or knob to facilitate removal.
