PROVISIONAL SPECIFICATION.
Improvements in Tobacco-pipes and Cigar-holders.
I, OSMOND YEADON RHODES, of 21 Leopold Street, New Leeds, Leeds, in
the County of York, Electrician, do hereby declare the nature of this invention to
be as follows:-
My invention has reference to tobacco-pipes and cigar-holders, the object of my
invention being to introduce a back pressure valve in a convenient place between
the bowl and the mouthpiece, which valve permits an up-draught for the passage of
smoke to the mouth, but prevents a draught in the opposite direction, so that
neither saliva and nicotine nor air can get past the said valve towards the bowl, by
which means the tobacco in the bottom of the bowl is kept dry and can therefore
be entirely consumed.
The tube or smoke-way between the valve and that end of the mouthpiece nearest
the bowl is made at an angle, the orifice of this tube nearest the bowl being
preferably on the upper side."
Any nicotine or moisture coming from the tobacco is arrested before it gets to
the valve and collected in a chamber provided for that purpose below the orifice of
the smoke-way in the mouthpiece.
Dated this 21st day of October 1890.

COMPLETE SPECIFICATION.
Improvements in Tobacco-pipes and Cigar-holders.
I, OSMOND YEADON RHODES, of 21 Leopold Street, New Leeds, Leeds, in
the County of York, Electrician, 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 has reference to tobacco-pipes, mouthpieces, and cigar holders, the
object of my invention being to introduce a back-pressure valve in a convenient
place between the tobacco bowl and the mouthpiece, which valve permits an up-
draught for the passage of smoke to the mouth, but prevents a draught in the
opposite direction, so that neither saliva, nicotine, nor air, can get past the said
valve towards the bowl, by which means the tobacco in the bottom of the bowl is
kept dry and can therefore be entirely consumed.
The tube or smoke-way between the valve and that end of the mouthpiece
nearest the bowl is preferably made at an angle, the orifice of this tube nearest the
bowl being preferably on the upper side.
The application of my invention to pipes is illustrated in the accompanying
drawings, wherein
Fig. 1 is a longitudinal section of a tobacco pipe having my improvements
applied thereto, and Fig. 2 is cross section taken through the line 1-2 of Fig. 1.
A represents the bowl of the pipe having a stem B of ordinary construction. In
the end of the stem BI insert a section C, the smokeway a being preferably at an
angle as shewn in the drawings, so that if any moisture is lodging in the bottom of
the stem B, it cannot get to the mouth through the inclined passage a, which
permits only dry smoke to pass therethrough. In the end of the section C is
screwed the mouthpiece D; the screwed end of the mouthpiece, however, does not
abut against the internal part of section C, but a cavity is left, into which is placed

page_text: a washer b, which forms a valve, so that when an updraught is made by the smoker,
the washer bis drawn against the end c of the mouthpiece, but as the said end c is
made with cross grooves as shewn at Fig. 3, the smoke will pass such grooves and
enter into the thbe of the mouthpiece, permitting a free passage for the up-draught
of smoke; but if the smoker blows down the pipe, the washer b will be forced
against the opening a and prevent the passage of wind or saliva, consequently the
tobacco in the bottom of the bowl does not become moistened and rendered unfit to
smoke, as is the case with pipes at present constructed.
"
Instead of the washer or valve 6 being placed in the position shewn in Fig. 1, it
may be placed in the opposite end of the mouthpiece D, a small washer d being
screwed in for the valve to act upon as described with regard to Fig. 1.
Although I have shewn and described the application of the valve to a tobacco-
pipe, it can with equal advantage be applied to cigar holders, hookahs, hubble-
bubbles, etc.
Having now particularly described and ascertained the nature of my said inven-
tion, and shewn in what manner the same may be applied, I would have it
understood that I do not limit myself to the form or construction of valve shewn
and described, as other adaptations of the back pressure valve than that shewn may
be employed; but what I do claim is :-
In tobacco-pipes, mouthpieces, and cigar holders, the combination therewith of a
back pressure valve applied in the manner and employed for the purposes sub-
stantially as described.
