PROVISIONAL SPECIFICATION.
Improvements in Tobacco Pipes.
SAMUEL KENYON, 61 Nether Hall Road Doncaster, Yorkshire, Engineer, do hereby
declare the nature of this invention to be as follows:-
The pipe is so constructed that no nicotine or tobacco juice is formed in the stem
or bowl-A valve is fixed or attached on the stem, and when the smoke is drawn by
the smoker into his mouth, the valve is closed by suction, but when the smoke is
blown from the mouth, the draught of the air in the stem is changod and the valve
opens, and at the same time all the nicotine in the stem of the pipe is discharged
through the open valve, before it has had time to become condensed and formed into
juice that is to say, each puff of smoke from the smoker's mouth also causes all
the nicotine then present to be discharged & got rid of, and there is consequently
never any collection of juice in the stem, it having escaped in the form of steam.
Dated this 29th day of January 1890.

COMPLETE SPECIFICATION.
Improvements in Tobacco Pipes.
SAMUEL KENYON 61 Nether Hall Road Doncaster, Yorkshire, Engineer, do
hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascerta ed in and by the following
statement:-
The immediate object of this invention is, to prevent the formation of moisture or
tobacco juice in the bowl or stem of a tobacco pipe, by preventing the accumulation
of saliva and also the condensation of the moist breath of the smoker which, with
the products of the tobacco and tobacco smoke, collects in a liquid form in the stem
of a tobacco pipe. The invention will be readily understood by reference to the
accompanying sheet of drawing, by which it will be seen that a valve (see Fig. 1. A)
is so arranged and employed by being fixed or attached on the stem of the pipe, in
such a position, as shewn in the drawing, that when the smoke is drawn into the
mouth of the smoker, the valve is closed by suction, but when the smoke is blown
from the mouth there is a backward draught or current of breath or air along the
stem of the pipe which causes the valve to open. That there is such a backward
draught will be seen by the slight puff of smoke which comes from the bowl of a
pipe at the same time a puff of smoke passes out of the smoker's mouth. The collec-
tion of liquid or tobacco juice in a pipe stem, arises to a great extent (i) from the
moisture in the tobacco itself which when heated forms tobacco steam, and (ii) by
the current of breath which as moist vapour is discharged into the pipe stem from
the smoker's mouth; thus there is soon an accumulation of tobacco steam and breath
but which cannot escape, which quickly becomes condensed and forms an unpleasant
liquid in the pipe stem. By the use of a valve this accumulation and condensation
is to a very great extent avoided and practically prevented, because the instant the
backward current of breath takes place the valve opens and allows the steam or moist
vapour to escape, before it has time to become condensed, and this is the object of
my invention. I do not limit myself to any material or any particular shape or form
of valve, and it is to be understood that a valve can be fitted in the saine way to a
cigar holder or to a cigarette holder.

page_text: 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
1. The employment of a valve attached or fixed to the stem, bowl, or any part of
a tobacco pipe, cigar holder, or cigarette holder, substantially as herein described
and illustrated by the annexed drawing, and for the purpose herein explained and set
forth.
