Improvements in Pipes and Tubes for Smoking Tobacco.
I, THOMAS CRADDock of 90 High Street, Marylebone in the County of Middlesex,
Butcher, do hereby declare the nature of this invention to be as follows:-
The present invention relates to improvements in pipes whereby the ejection of the
nicotine from the stem thereof is provided for, without necessitating the removal of
the pipe from the lips or the charge of tobacco from the bowl.
In carrying out my invention, I construct a pipe with a ball valve at the end of the
stem near the bowl, so arranged that the normal position of the ball will be on its
seat, and the valve therefore closed, when the pipe is in the smoker's mouth.-Should
the smoker wish to clear the stem of the pipe, he will only have to blow, covering at
the same time the bowl with his hand, and the opening of the ball valve will allow the
obnoxious juice to the forced out by the smoker's breath. Shoulders or projections
are provided for retaining the ball of the valve when off its seat. The ball, however,
again takes its normal position, and the valve is closed, when the smoker leaves off
blowing and recommences to draw in.
It is obvious that this invention, besides being applicable to pipes, is also applicable
to some forms of cigar and cigarette tubes, for instance, those of a curved pattern.

page_text: I THOMAS CRADDOCK of 90 High Street, Marylebone in the County of Middlesex
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 present invention relates to the improvement of Tobacco pipes with the object
of preventing the fouling thereof.
To this end the ejection of the nicotine from the stem of the pipe is provided for in
such a manner that the smoker may cleanse his pipe without having the trouble of
removing the pipe from his lips or the charge of tobacco from the pipe bowl.
In carrying out my invention I construct a pipe with a ball valve at the end of the
stem near the bowl so arranged that the normal position of the ball closing the valve
will be on its seat when the pipe is in the smokers mouth.
Should the smoker wish to clear the stem of the pipe he will only have to blow,
covering at the same time the bowl with his hand. The pressure of the smokers
breath will remove the ball from its seat and open the valve thus allowing free escape
for the noxious juice as it is being forced out.
A projection is provided for retaining the ball within the recess wherein the valve
is placed when off its seat. The ball takes again its normal position and closes the
valve as soon as the smoker leaves off blowing and recommences to draw in.
In the accompanying drawing I have shewn in sectional elevation a Tobacco Pipe
with my invention applied thereto.
A is the pipe in the bowl of which is drilled a tapered inclined recess B forming a
continuation of the bore of the stem. Within the recess B is a ball of some heavy
non-porous substance such for example as lead and of such size as to bed upon the
lower or smaller end of the recess B between which and the pipe stem it forms a
valve.
When the pipe is in use the ball b by reason of the recess B being inclined will lie
upon its seat and close the passage between such recess and the stem of the pipe, but
as soon as the smoker begins to blow, placing his hand over the top of the bowl at the
same time, the ball will be forced from its seat to the upper or larger end of the
recess B and a free passage will be opened through which the necotine can be blown.
The ball is prevented from escaping from the recess B by the pin or projection 71

page_text: and is therefore ready to resume its seat and close the valve as soon as the smoker
leaves off blowing and recommences to draw in.-The recess B is preferably lined
with metal but this is not necessary for the efficient operation of the valve.
From the above description it will be understood that inasmuch as the clearing of
the pipe stem is a very simple matter which can be constantly effected the fouling
of the pipe can readily be prevented.
It is obvious that this invention besides being applicable to pipes is also applicable
to some forms of cigar and cigarette tubes for instance those of a curved pattern.
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 :-
Providing for the cleansing of Pipes and Tubes for smoking tobacco substantially
in the manner shewn and described.
