Improvements in Tobacco Pipes.
I, WILLIAM JOHN BROWN, Senior, of No. 1 Bohn Street, Stepney, Tobacco
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 :-
This invention more particularly relates to tobacco pipes which are made of
clay, and has for its object to so construct such pipes as to prevent the nicotine
and other deleterious products of combustion entering the mouth of the smoker.
This I effect by the means illustrated in the accompanying drawings, which
shew views in longitudinal section of a clay pipe made according to my invention.
Similar letters indicate corresponding parts in both figures.
To carry out my invention I fit a pipe with a filtering tube a, preferably made of
glass, wherein is an asbestos packing 6; or any other suitable absorbent material,
such as cotton fibre, may be employed. Through this packing the smoke is
filtered and purified before it is inspired, the nicotine and other deleterious
products of combustion being absorbed and intercepted thereby, and thus prevented
from entering the mouth. To allow of the filtering tube being cleansed, and also
of the packing being cleaned or renewed, a plug c is fitted in the filtering tube.
Such plug may either be hollow, so as to form a washer, as shewn in Figure 1, or
it may be solid and inserted in a perforated shoulder d formed on the outer
extremity of the pipe stem, as shewn in Figure 2 (which shews a modified arrange-
ment of my invention,) so as to close the aperture in such shoulder which forms
a socket to receive the lower end of the filtering tube a, while its upper end is fitted
in a corresponding shoulder formed on the bowl of the pipe. e is a smoke
channel formed in the bowl of the pipe through which the smoke ascends and then
passes down through the filtering tube a and thence into the smoke channel in the
pipe stem. The advantage of this modified arrangement is that the smoke passes
through a more circuitous channel. Or the filtering tube may be fitted in a
suitable recess formed on or in the pipe.
I would here observe that I do not confine myself to the precise details of
construction and arrangement herein before described and shewn as the same admit
of variation without departing from the essential feature of my invention which is
providing a clay pipe with a filtering tube containing asbestos or other suitable
absorbent packing that intercepts the nicotine and other deleterious matters, and
prevents the same entering the mouth.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to he performed I declare that what I
claim is;
1. As a new article of manufacture a clay tobacco pipe having a filtering tube a
containing asbestos or other suitable absorbent packing b, all substantially as
hereinbefore described and shewn.
2. In combination with such filtering tube a, a plug e which may either be hollow
or solid all substantially as hereinbefore described and shewn.

tobacco pipe, for the reception of a filtering tube all as herein before specified.
