Improvements in Tobacco Pipes.
We ULYSSE VINCENT, CHARLES BONDIER & JABEZ CHARLES of St. Claude,
Jura, France, and 268 High Street Stratford, England, Briar Pipe Manufacturers,
do hereby declare the nature of this invention to be as follows:-
This invention has for its object to keep the tobacco dry until consumed by pro-
tecting it from the moisture of the mouth. To effect this we fit the stem of the
pipe with a perforated chimney screwed or otherwise attached to such stem and
which communicates through a small duct with the channel in the mouth piece of the
pipe. Such chimney is fitted internally with a small ball which serves to close,
the communication with such mouth piece as presently described. We likewise fit
the stem of the pipe internally with a small tubular chamber perforated at both
ends and containing a second small ball which on drawing the smoke through the
pipe is shifted by the force of the aspiration sufficiently to allow a free passage to
the smoke while the ball contained in the chimney is by such aspiration caused to
hermetically close the latter. On blowing through the pipe such action is reversed
the ball contained in the tubular chamber closing the front aperture of such
chamber while the ball in the chimney is released from the mouth of the duct com-
municating with the channel in the mouth piece as already described thus allowing
the moisture from the mouth to escape through such chimney. By this double.
action the object of our invention is easily and perfectly attained as the tobacco is
protected from the moisture of the mouth and so kept dry until consumed.

Improvements in Tobacco Pipes.
We, ULYSSE VINCENT, CHARLES BONDIER, and JABEZ CHARLES, of Saint
Claude, Department of Jura, in the Republic of France, Smoking-pipe Manu-
facturers, 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 :-
This invention relates to improvements in smoking pipes and has for its object
to provide means whereby the tobacco is retained absolutely dry during smoking
by preventing the smoke, which has been drawn from the bowl and which is
rendered moist in the mouth of the smoker, to return into the bowl.
To remedy this defect we have isolated the bowl by means of a ball valve so as
to stop the return of smoke or moisture from the mouth of the smoker through
the passage which leads to the bowl.
And in order that our invention may be more fully understood, we have caused
to be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a longitudinal section of the stem of the pipe, showing its action when
drawing smoke.
Fig. 2 a longitudinal section of the pipe complete showing the smoke and
moisture prevented from returning into the bowl.
.
Fig. 3 is an elevation of a portion of the stem of the pipe and
Fig. 4 is a modification of the invention shown in the previous figures.

page_text: Our invention consists principally in a ball valve which serves as an automatic
obstruction and which closes or opens alternately the passage in the stem
according to the direction which the smoke takes.
On the smoker drawing a mouthful, the ball A, Fig. 1, moves..
..back from
the orifice B communicating with the pipe bowl owing to the suction created and
frees the orifice B. The ball F which communicates with the atmosphere through
holes b. b. closes the respective exhaust passage owing to the rarefaction of the air
which takes place in the interior of the pipe.
When the smoke returns by the smoker breathing, it produces moisture, the
ball A, Fig. 2, then completely obstructs the orifice B and the ball F, under
the influence of the interior pressure, drops and uncovers the holes b. b. whereby
the returned smoke is permitted to escape and the tobacco in the bowl thus kept
completely free of moisture.
As will be seen from Fig. 3, the extremity of the tube containing the ball A is
serrated, so that in case of a strong draught the ball A may place itself behind the
orifice of this tube and let the smoke pass through the serrations, thus not
impeaching its passage to the mouth.
Our system of ball valve obstruction may be employed in any form of pipe and
carried out in different ways, for instance also as shown in Fig. 4, without departing
from the principal of our invention, i.e. in drawing the smoke, the ball A displaces
itself in the passage of the stem, to free it whilst the ball F in the exhaust passage
closes it owing to atmospheric pressure externally the contrary taking place on the.
sinoke returning.
.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed, we declare that what we
claim, is-
1st. The general construction and combination of parts constituting our improve-.
ments operating substantially as and for the purpose set forth.
2nd. A ball A closing or opening the passage B leading to the pipe bowl,
as well as a ball F. opening or closing the holes b. b. of the exhaust passage,
the said ball valves having an automatic and. absolutely contrary functions
on the smoke leaving or returning, whereby the tobacco in the bowl is retained
always dry and cut off from moisture, substantially as set forth.
