An Improvement applicable to Tobacco Pipes.
I WILLIAM NOCK of Newfield House Sandbach in the County of Chester
Schoolmaster, do hereby declare the nature of this invention to be as follows:-
This invention relates to pipes used for smoking tobacco and the objects of the
invention are to prevent the drawing of the nicotine or ashes into the mouth of the
smoker and to make the pipe smoke cool and sweet.
The invention consists principally of a metal thimble or cup the sides of which
are grooved or fluted vertically so as to leave a series of passages all round
between it and the interior of the bowl, into which it is fitted closely, these passages
all leading into the space at the bottom of the bowl below the cup.
Inside the fluted metal cup is fitted a metal thimble or conical tube or lining open
at each end, this tube being shorter than the inside of the cup and having a rim or
flange outside at the top fitting closely inside the bowl of the pipe, the flutes of the
cup forming also another series of passages between the cup and the lining.
The cup and lining may be made of any other suitable material than metal.
The tobacco is placed inside the lining and the smoke first ascends the passages
between the lining and the fluted cup, over the top of the latter and then down the
other series of passages between the fluted cup and the bowl to the space at the
bottom and so to the stem and mouth piece.
The nicotine remains in the bottom of the cup, and can be readily cleaned out by
removing the inner tube or lining.

1, WILLIAM NOCK, of Newfield House, Sandbach Cheshire, Certificated Master
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 invention consists first, of a cup or bowl (1) the top & sides of which are
grooved or fluted so as to leave a series of continuous passages between itself & the
interior of the bowl of the tobacco pipe, & also between itself & the second bowl or
lining (2) to be described hereafter.
These passages all lead to the bottom of the bowl of the tobacco pipe, & thus
have a direct communication with the bore of the stem & mouthpiece.
Secondly, of another bowl or lining (2) open at the top, & open or perforated at
the bottom.
This bowl or lining is fitted inside the first one, & also fits closely & firmly to
the bowl of the tobacco pipe above the first cup or bowl by means of a worm,
(corresponding to one on the bowl of the tobacco pipe), or wedge shaped rim or
flange which is fitted either upon the inside or outside of the bowl of the tobacco
pipe (3).
The fluted cup or bowl & bowl or lining are made in each case of any & all
materials suitable for the purpose.
The tobacco is placed inside the bowl or lining (2) & when ignited, the smoke

bowl (1) then it passes over the top of the fluted cup or bowl & down the other
series of passages between the fluted cup or bowl (1) & the inner side of the bowl
of the tobacco pipe (3) to the bottom of the tobacco pipe & so on to the stem &
mouthpiece.
Having now particularly described & ascertained the nature of my said inven-
tion, & in what manner the same is to be performed, I declare that what I
claim is
That the fluted cup or bowl (1) creating three passages two downwards & one
upwards is new.
