Improvements in Pipes for Smoking Tobacco.
I, WILLIAM HENRY CARRINGTON, of 55, Thomas Street, in the City of
Manchester, 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 :-
My invention relates to a pipe for smoking tobacco, and has for its object to
provide improved means for preventing nicotine from entering the mouth and
moisture from the mouth from entering the bowl.
In carrying out my invention I make the bowl detachable from the stem and
arrange between the said bowl and stem a chamber containing a piece of absorbent
material and in communication with the interior of the bowl. In the underside
of the bowl is a channel connected by passages with the said chamber and with
the mouth-piece.
To enable my invention to be fully understood I will describe the same with
reference to the accompanying drawing, in which:-
Figure 1 is a side elevation partly in section of a pipe constructed according to
my invention:
Figure 2 is a section on the linear Figure 1:
Figures 3 and 4 are respectively views of the bowl and stem of the pipe detached
from one another:
Figure 5 is an underside view of the bowl; and,
Figure 6 is a plan view of the stem shewn in Figure 4.
a indicates the bowl of the pipe, and 6 the stem, the said bowl being provided
with a screw-threaded extension c adapted to be inserted in the screw-threaded
aperture d of the stem. e is the chamber formed between the bowl and stem,
and is the channel formed around the underside of the bowl, and communicating with
the said chamber by means of passages g, g. h is a channel extending from the
channel to the bore of the pipe-stem, and j, j are openings between the bowl
and the chamber.
The underside of the extension c upon the bowl is hollowed out or recessed,
as shewn at k Figure 3, and in the bottom of the chamber e, immediately
beneath the recess k, is formed a corresponding recess 7, the said recesses k and
serving to hold absorbent material such as wadding or asbestos fibre.
When using the pipe the smoke passes from the bowl through the passages j, į
thence through the absorbent material (whereby the nicotine will be separated
from the smoke) into the chamber e, thence through the passages g, g into the
channel and thence through the passage h to the bore i, whence it passes to the
mouth of the smoker. It will be obvious that owing to the peculiar arrangement
of the channels no moisture from the mouth can enter the bowl.
An important feature of my improved pipe is that it can be easily cleansed, the
piece of absorbent material being readily removed and replaced.
my said
Having now particularly described and ascertained the nature of
invention and in what manner the same is to be performed. I declare that what I
claim is :-
The manufacture and use of the improved pipe for smoking tobacco herein-
before described and illustrated in the several figures of the accompanying drawing.
