Improvements in Tobacco Pipes.
I, THOMAS ANDERSON, residing at 11 Russell Avenue, Watertown, in the
County of Middlesex and State of Massachusetts, United States of America,
Medical Doctor, 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:-
The accompanying drawing represents a vertical section of my improved pipe
and lining.
The object of my invention is to provide a pipe by the use of which the smoker
will obtain the greatest amount of pleasure and benefit with the least liability of
tainting his clothes and breath, and one which will practically separate from the
smoke the poisonous and disagreeable substance known as the oil of tobacco.
A designates the bowl of the pipe which is provided with the perforated
bottom B and a cotton (or other absorbent) receptacle C beneath the perforated
bottom.
The pipe stem D has the usual smoke passage E. The absorbent cotton is
shown in the receptacle in the bottom of the bowl and is designated by the
letter G.
I design to make the lining H and its oval bottom of tin, brass, porcelain, glass,
clay or any other suitable material which will not be destroyed by the burning
tobacco in the pipe. A cap H' may be used and the tobacco in the pipe saved
from being wasted by the pipe continuing to smoke after the user has taken it from
his mouth. I make the bottom B concave on its under side but in practice I find
it advantageous to form a shoulder on the inside of the bowl of the pipe which
serves as a rest for the curved bottom B. It is obvious however that the bottom B
may be fastened to its place in various ways without departing from the spirit of
my invention.
From the foregoing it will be readily understood and appreciated that the smoke
is cooled and purified before it reaches the smoker's mouth. Products of com-
bustion during the process of smoking will not choke up and soil and taint the
bottom of the pipe.
The bottom and inner lining will save the bowl of the pipe from useless burning
and the pipe can be smoked with a much shorter stem as the heat of the smoke is
virtually gone by the time the smoke has been drawn through the absorbent in the
base of the bowl.
In addition to this, the disagreeable and nauseating effect experienced on account
of the inhalation of ashes and moist and tainted tobacco saturated with saliva and
the oil of tobacco, is entirely avoided.
Another feature of prime importance is the fact that this pipe can be cleansed by
removing the lining and the absorbing cotton to such an extent that the disagree-
able odour which generally accompanies a pipe and which permeates the clothing of
the smoker who carries his pipe with him is practically dispensed with.
It will be seen at a glance that an acute-angled imperforate receptacle is formed
at the junction of the outer edge of the bottom and the lower edge of the lining
and as the curved bottom is formed with the concave on the under side so that
the oil of tobacco, condensed vapor, etc., will run down towards and into the
receptacle formed and there remain until the pipe is cleansed and when the lining
and bottom B is removed to facilitate the cleansing of the pipe, all accumulated
oil, moisture and matted tobacco are removed with it and the bowl is left sweet
and clean on the inside.
By the use of a curved bottom provided with a projecting vertical lining H,

page_text: the accumulated oil, moisture, and matted tobacco at the bottom of the column
of tobacco in the pipe, will not adhere to the pipe, thus tainting and smearing
of the inner surface of the pipe at that point will be avoided. At the same
time the lining may be made so light that it will not add materially to the weight
of the pipe.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
In a sanitary pipe of the character described, a hollow pipe bowl formed to
afford an absorbent receptacle in its bottom and provided with a projecting ledge
or shoulder above and around the absorbent receptacle in combination with a
cylindrical lining fitting snugly against the inner walls of the pipe bowl and resting
on the outer upper edge of the shoulder in the bowl and having a bottom concave
on its underside secured to the lining and provided with perforations about its
centre only constituting a lining which has an acute-angled imperforate recess at
its lower outer edges, the apex of the acute angle at the bottom of the lining's
edge excluding all moisture from the edges of the pipe, the said bottom having a
raised central portion above and away from the absorbent in the bottom and the
ledge in the pipe bowl projecting between the concave bottom of the lining and the
acute-angled edge of the lining whereby it separates them and the absorbent in
the bowl, as and for the purpose described.
