PROVISIONAL
SPECIFICATION.
Improvements in Tobacco Pipes.
I, FREDERICK NORTH, of No. 16 Albion Square, Dalston, in the County of
Middlesex, do hereby declare the nature of this invention to be as follows:-
The objects of this invention are to produce a tobacco pipe in which the smoke
is automatically freed from nicotine and other noxious residues and which allows
the smoke to be inhaled free of moisture. To protect the tobacco from moisture
so that it may be all consumed, and to collect and retain moisture and residues so
that they are not evaporated and may be drawn off.
These objects are effected by providing as has before been proposed a double
bowl with a space between them. This space however is divided into compartments
so that the smoke is caused to pass in a circuitous course round the inner heated
bowl till it reaches the top of the space where it passes through a passage in a
projection from the top of the outer bowl into the stem. The nioisture and
residues produced fall towards the bottom of the outer bowl and are conducted
through a passage in a projection at the bottom of the outer bowl into a cap so that
they are not evaporated but are retained and may be drawn off.
Dated this 22nd day of January 1894.
COMPLETE SPECIFICATION.
Improvements in Tobacco Pipes.
I, FREDERICK NORTH, of No. 16 Albion Square, Dalston, in the County of
Middlesex, England, Solicitor, 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 objects of this invention are to produce a tobacco pipe in which the smoke
is automatically freed from nicotine and other noxious residues and which allows
the smoke to be inhaled free of moisture; also to protect the tobacco from moisture
so that it may be all consumed, and to collect and retain moisture and residues so
that they are not evaporated and may be drawn off.
These are effected by making a double bowl and dividing the space left between
them into compartments by a band or bands so that the smoke is caused to pass in
a circuitous course round the inner bowl till it reaches the top of the space whence
it passes through a passage in a projection from the top of the outer bowl into the
stem. The moistures and residues produced fall towards the bottom of the outer
bowl and are conducted through a wide passage in a projection at. the bottom of
the outer bowl into a cap where they are retained so that they are not evaporated
and may be drawn off.
Referring to the accompanying drawings:

The inner bowl has a bevelled shoulder "a," and may screwed to the outer bowl
as shown at "b." It is perforated as shown at " C and has a band "d" round it
forming a division. The band fits against the walls of outer bowl, and has a
passage "e" through it at the part opposite the passage

spiral or there may any number of such bands to effect the same purpose viz. the
circulation of the smoke in the space "f" between the bowls. The outer bowl has
a projection "g" at the top, and a projection "h" in the same straight line at the
bottom. The rim is bevelled at "j" corresponding with shoulder of inner bowl.
Projection "g" is hollowed at "k" to receive the stem. The bottom of the
hollow is countersunk as shown; and the passage m is made through the
projection into the hollow, from as near the top of the upper compartment as
possible. The bottom of the outer bowl is widely hollowed out as shown at
as is also projection "" thus forming a wide drain "p" into the cap "q." The
smoke is drawn through "c into the lower compartment of space "f" where it
expands and circulates. Thence it is drawn through "e" into the top compartment
where it again expands and passes round the inner bowl into the passage "m" and
thence into the stem. The residues and moistures produced drain freely into the
cap from whence they may be thrown off.

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 :-
(1.) The band with the passage through it as above described and shown on the
:said drawings.
(2.) The outer bowl having the wide opening through the bottom, with the
projection at the top having the passage through it, and the projection at the bottom
with the wide drain as above described and shown on the said drawings.
(3.) The combination of an inner bowl having the band above described, with
the outer bowl having the projections, wide opening, passage and drain above
.described.
