COMPLETE SPECIFICATION.
An Improvement in Pipes for Smoking.
I, CHARLES CAYRON of St. Claude, Jura, France, Pipe Manufacturer, 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:-
My invention has for its object to provide a pipe for smoking which will present
the appearance of an ordinary wood pipe and yet possess the absorptive and other
qualities of a clay pipe which are of so much importance from a hygienic point of
view.
The invention consists of a pipe having an outer bowl of wood furnished with a liner
made of enamelled clay of which the basis is silicate of magnesia thus being identical
with the composition of meerschaum and possessing the same absorbent qualities.
This liner is screwed into the outer bowl so as to be readily removable in order that
and
it may be replaced by another, should it be damaged or become too foul for use,
it is provided with a flange at top which abuts against the edge of the wooden bowl.
The lower part of the liner is rather smaller than the bowl so as to leave a space
hetween the two, and it has a hole at or near its lower part which is in communication
with the hore of the stem of the pipe.
It is obvious that the wood bowl of the pipe will be protected from burning, as the
tchacco is wholly contained in the enamelled clay liner while the space between the
bowl and liner will prevent the transmission of heat.
In the accompanying drawings, the liner is shewn separately in Figure 1, Figure 2
being a longitudinal section of the pipe shewing the liner in place in the wood bowl.
a is the clay liner which is approximately of the same shape as the wood bowl b. It
is formed with a flange or rim a at top, the under surface of which flange, when the
liner is in place, abuts against the edge of the wood bowl. In the drawings, the
flange or rim is shewn as bevelled but this is immaterial so long as its contour
harmonizes with the wood bowl sufficiently to render it undistinguishable therefrom.
To this end, the flange would preferably be browned or colored by a suitable glaze or
enamel to give it the appearance of wood. The flange effectually protects the edge of
the wood bowl from being burnt. The liner a is somewhat smaller than the wood
bowl 6 (except at its screwed part) so that it does not entirely fill the latter, thus leaving
a space which prevents the transmission of heat to the bowl.
The pipe illustrated has a detachable mouthpiece c which is provided with a headed
extension c¹ adapted to pass through the bore of the stem, the head on such extension
serving to remove the nicotine which is deposited in the stem, but I do not limit
myself to a pipe of this character.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is ;-
A pipe for smoking, having an outer bowl of wood and a liner of enamelled clay
which is secured in the bowl by a screw-connection, said liner being provided with a
rim or flange which abuts against and protects the edge of the bowl of which it forms
an apparent continuation, substantially as described and shewn in the drawings.
