I, WALTER GEORGE PARKIN of Fargate, Sheffield in the County of York Glass
and China Merchant, do hereby declare the nature of my said invention for IMPROVE-
MENTS IN SMOKING PIPES to be as follows:-
My invention of improvements in smoking pipes has for its object to improve the
"draw," and to cause the tobacco to be more effectively consumed, and generally to
render the pipe more agreable to the smoker.
It consists in forming grooves or air passages in the face of the inner surface of the
bowl, such grooves, channels, or air passages, being formed either by pressure in
moulds, or by cutting tools, or by other suitable means.
The grooves or air channels may be of any desired number, size, or configuration,
as for example, eight equidistant vertical grooves from the top to the bottom of the
bowl will serve to illustrate my invention."
The tobacco may be pressed very firmly into the bowl of the pipe without interfering
with the "draw" of the pipe, and oweing to the admission of air to the outside of the
tobacco down the air channels, the consumption of the tobacco is more regular and
perfect, and as a consequence the pipe is cleaner.
Although I have given as an example, a bowl having eight vertical grooves,
may
as before mentioned use any number of such grooves or channels, and they may be
made to pass down the bowl in a spiral form if desired, and be of any cross sectional
shape.

page_text: I, WALTER GEORGE PARKIN of Fargate, Sheffield in the County of York Glass
and China Merchant do hereby declare the nature of this invention and in what
manner the same is to be performed, to he particularly described and ascertained in
and by the following statement :-
My invention of improvements in smoking pipes has for its object to improve the
"draw," and to cause the tobacco to be more effectively consumed, and generally to
render the pipe more agreable to the smoker.
And in order that my invention may be fully and clearly understood, I have annexed
a sheet of drawings Illustrating same in which similar letters of reference indicate
similar parts in both figures.
Fig. 1. Is a side view of a Pipe showing the bowl in section.
Fig. 2. Is a top view or plan of same.
In carrying out my invention I form grooves channels or air passages A, in the
face of the inner surface of the bowl B, and leading to the air passage C, in the tube D,
as shown in Fig. 1, such grooves, channels, or air passages being formed either by
pressure in moulds, or (in the case of wood pipes) by cutting tools, or by any other
suitable means.
The grooves, channels, or air passages A may be of any desired number, size, or
configuration, as for example eight equidistant vertical grooves made from the top to
the bottom of the bowl, such as shown in the drawing, will serve to illustrate my
invention and answer well in practice.
The tobacco may be pressed very firmly into the bowl of the pipe without interfering
with the "draw" of the pipe, and oweing to the admission of air to the outside of
the tobacco down the air channels A, the consumption of the tobacco is found in
practice to be more regular and perfect, and consequently the pipe is kept clean.
Although I have given, as an example, a bowl having eight vertical grooves, I may
as before mentioned use any number of such grooves, or channels, and they may be
made to pass down the bowl in a spiral form if desired, and be of any cross sectional
shape.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is :-
A Smoking Pipe having in the interior face of the bowl, a number of air passages,
channels or grooves, for the purpose specified, and substantially as hereinbefore
described and illustrated.
