PROVISIONAL SPECIFICATION.
Tobacco Pipes.
1, WILLIAM SNOW ROGERS, of 7, Addison Road, Chiswick, in the County of
Middlesex, Engineer do hereby declare the nature of this invention to be as
follows:-
My invention relates to tobacco pipes, and consists in a means for more efficiently
cleansing the internal parts of such pipes from moisture, oil, nicotine and other
matters which may collect therein.
1 form a chamber in that part of the pipe stem which immediately adjoins the
bowl, in which these matters may condense and become deposited. Near to, and
preferably opposite to the point where the perforation from the bottom of the pipe
bowl enters the chamber in the stem, I provide another perforation (which may
conveniently constitute a continuation of the first-named perforation) communicating
with the outside of the pipe.
In connection with these two perforations, and with the chamber in the pipe
stem which for convenience of description I will call the condensing chamber-I
employ a device which performs the function of a "two-way cock," the purpose of
which is to enable the smoker to establish or to cut off, at will, communication
between the pipe bowl and the condensing chamber, and at the same time corre-
spondingly to close or open communication between the condensing chamber and
the outside of the pipe.
When the "two-way cock" is set so as to connect the pipe bowl with the
condensing chamber, the pipe is in condition for smoking, whilst, if it is set so as to
connect the condensing chamber with the outside of the pipe, the liquid and other
matters, which may have collected in the chamber, may be ejected by blowing
forcibly down the pipe stem.
It is obvious that my invention may be operated during smoking, and without
disturbing the tobacco in the bowl of the pipe, thus rendering it unnecessary to
put out" the pipe when it is desired to cleanse the interior.

Instead of using a "two way cock" or similar device which requires to be
operated by hand, I sometimes employ a valve or valves, arranged so as to allow of
free communication from the pipe bowl to the condensing chamber, and from the
condensing chamber to the outside of the pipe, accordingly as the pipe
through or blown through.

COMPLETE SPECIFICATION.
Tobacco Pipes.
I WILLIAM SNOW ROGERS of 7 Addison Road Chiswick in the County of
Middlesex Engineer 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:—
My invention relates to tobacco pipes and consists in a means for more efficiently
cleansing the internal parts of such pipes from moisture oil nicotine and other
matters which may collect therein.
I form a chamber in that part of the pipe stem which immediately adjoins the
bowl in which these matters may condense and become deposited. Near to and
preferably opposite to the point where the perforation from the bottom of the pipe
Pin1

page_text: bowl enters the chamber I provide another perforation (which may conveniently
constitute a continuation of the first named perforation) communicating with the
outside of the pipe.
In connection with these two perforations and with the chamber in the pipe stem
which for convenience of description I will call the condensing chamber I employ a
device which performs the function of a "two-way cock" the purpose of which is
to enable the smoker to establish or to cut off at will communication between the
pipe bowl and the condensing chamber and at the same time correspondingly to
close or open communication between the condensing chamber and the outside of
the pipe.
"
When the "two-way cock is set so as to connect the pipe bowl with the
condensing chamber the pipe in condition for smoking whilst if it is set so as to
connect the condensing chamber with the outside of the pipe the liquid and other
matters which may have collected in the chamber can be ejected by blowing
forcibly down the pipe stem.
An important feature of this invention is that it may be operated during smoking
without disturbing the tobacco in the bowl of the pipe thus rendering it unnecessary
to put out the pipe when it is desired to cleanse the interior.
The nature of this invention will be more clearly understood by reference to the
accompanying sheet of drawings in which
Figure 1 shews of a tobacco pipe in which the "two-way cock" takes the form
of a conical plug A closing the end of the condensing chamber B the smaller end of
this plug is cut at an angle to its axis or otherwise shaped in such a manner that
when the plug is turned round the perforations C and D are alternately put into
communication with the chamber B. In this figure the pipe is shewn in condition
for smoking.
Fig. 2 shews in part a similar pipe with the plug A turned so as to admit of the
condensed matters being ejected from the chamber B by blowing down the stem of
the pipe.
Figure 3 shews another method of carrying out my invention by the use of a
plug or cock E inserted at the base of the bowl and operated from the side like an
ordinary gas tap.
To prevent the condensed matters from running along the outside of the pipe I
provide the perforation D with a bush or tube of any suitable material projecting
slightly below the bottom of the pipe as indicated in the drawings.
I do not confine my invention to any particular shape or form of pipe it being
applicable to nearly every ordinary pattern of pipes for smoking and to pipes of
various materials also I do not confine myself to any particular form of two-way
cock, but I employ such a device as may be most suitable for the particular form or
class of pipe to which this invention is being adapted.
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. In a tobacco pipe the combination of a rotating plug with a condensing
chamber and cross passages substantially as and for the purpose specified.
2. The improved tobacco pipe substantially as described and illustrated at
Figures 1 and 2 of the accompanying drawing.
3. The improved tobacco pipe substantially as described and shewn at Figure 3
of the accompanying drawing.
