AN IMPROVED PIPE FOR SMOKING
Year: 1860

page_text: LETTERS PATENT to Franz Jaburek, of Vienna, in the Austrian Empire,
Manufacturer, for the Invention of "AN IMPROVED PIPE FOR SMOKING."
Sealed the 29th May 1860, and dated the 31st March 1860.
PROVISIONAL SPECIFICATION left by the said Franz Jaburek at the
Office of the Commissioners of Patents, with his Petition, on the 31st
March 1860.
I, FRANZ JABUREK, of Vienna, in the Austrian Empire, Manufacturer, do
hereby declare the nature of the said Invention for "AN IMPROVED PIPE FOR
SMOKING," to be as follows:-
My Invention has chiefly for object to prevent the noxious oils and juices of
tobacco from passing into the mouth of the smoker, and also in respect of
meerschaum pipes to accelerate the "coloring" thereof. I propose to fit or
form a perforated disc or false bottom with orifices through it, within the pipe
bowl above the regular bottom thereof, placing such disc or false bottom so
as to leave a suitable space between it and the real bottom of the bowl; the
juices and oils of the tobacco drop or percolate through the perforations or
orifices in the disc or false bottom and can be readily removed on pulling out
the mouthpiece. For further preventing the juices from being drawn into
the lips, a plug or piece of cork or other suitable material may be fitted to
the mouthpiece and inserted into the pipe stem, extending therein to a
desirable length; this plug or inner piece has through it from end to end a
central longitudinal channel for the passage of the smoke, of much smaller
diameter or bore than that of the stem, but in other respects the said plug
completely fills up that part of the stem through which it passes.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FRANZ
JABUREK, of Vienna, in the Austrian Empire, Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirty-first day of March, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Franz Jaburek, Her special licence that I, the said Franz Jaburek,
my executors, administrators, and assigns, or such others as I, the said Franz
Jaburek, my executors, administrators, and assigns, should at any time.
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "AN IM-
PROVED PIPE FOR SMOKING," upon the condition (amongst others) that I, the
said Franz Jaburek, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said Franz Jaburek, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, reference being had to the accompanying Drawings, and to
the letters and figures marked thereon, that is to say:-
The chief object of my Invention is to prevent the noxious oils and juices of
tobacco, while being smoked, from passing into the mouth of the smoker; also
in respect of meerschaum pipes, to accelerate the "coloring" thereof. For
these purposes, according to my Invention, a perforated disc or false bottom,
having orifices through it, is fixed or formed within the pipe bowl above the
regular bottom thereof, such disc or false bottom being so placed as to leave a
space between itself and the real or regular bottom of the bowl; the juices
and oils of the tobacco drop or percolate through the perforations or orifices in
the disc or false bottom into the space beneath, and may be readily removed
on pulling out the mouthpiece. For farther preventing the juices from being

page_text: drawn into the lips of the smoker, a plug, preferably of cork, may be fitted to
the mouthpiece, and inserted into the pipe stem, extending therein to any
desired length; this plug or inner piece has through it, from end to end, a
central longitudinal channel for the passage of the smoke, of much smaller
diameter or bore than that of the stem, but in other respects the said plug
completely fills up that part of the stem through which it passes.
The accompanying Drawings more particularly exemplify my Invention
and represent the mode in which it may be carried into effect.
Figure 1 is a sectional view of a pipe to which my Invention is applied. A is
the pipe bowl; B, the stem: C, the mouthpiece; D, shewn in plan, Figure 2,
is a disc, which I prefer to construct of the same material as that of the bowl,
and cement into the bowl a little above the bottom thereof, so that this disc
forms a false bottom, and leaves between itself and the regular bottom of the
bowl a small space or chamber 6; the piece D is perforated with orifices d, d,
passing quite through it. I do not confine myself to any particular number of
perforations d, but five, as shewn, are sufficient.
process
of
The tobacco, while being smoked, rests on the false bottom D; the oils and
juices given off by it percolate through the orifices d, d, into the space b, where
they collect, and the bottom of this space being at a lower level than the bore
of the stem, they are thus prevented from being drawn up through the stem
into the smoker's mouth; moreover, moisture being by these means separated
from the burning tobacco, the dry heat of the latter accelerates the
what is called "coloring" the bowl, especially when the latter is of meer-
schaum. Figure 3 is a side elevation, and Figure 4 an end view, of the mouth-
piece C and plug E detached; E is a plug or cylindrical piece of cork screwed
into the inner end of the mouthpiece C, and extending some way within and
along the stem, as shewn; this plug is of such shape and size as to fill up
that part of the stem along which it extends, except that there is formed
through it, from end to end, a central channel e, of much smaller diameter
than the bore of the stem. If any of the juices should escape up the stem and
gather on its inner surfaces, they would be prevented from reaching the
smoker's lips by means of this plug, while the channel e affords the required
passage for the smoke. On withdrawing the mouthpiece the oils and juices
collected in the space b and in the stem may be readily removed. I consider
cork the material most suitable for the manufacture of the plug E from its
resilience and softness; it forms a tight joint and does not bear with such
pressure against the "meerschaum" as to be liable to split it; but if a more
rigid material were employed for the purpose, a screw or other fastening
should be used to keep the junction between stem and mouthpiece air-tight.

page_text: In pipes furnished with what is called a "mounting," the plug should preferably
extend within that portion of the stem surrounded by this "mounting," that
part being strengthened by the mounting, and less liable to split.
And having now described the nature of my said Invention, and in what
manner the same may be performed, I declare that it relates to an improved
pipe for smoking, and what I claim as new therein is,―
First, the application in the construction thereof of a perforated disc or false
bottom D fixed or formed within the bowl above the real or regular bottom
thereof, and leaving a space between itself and the regular bottom, for the
purposes herein described.
Second, the employment, in combination with the use of the aforesaid false
bottom or disc of a plug E, arranged in the manner and for the purpose
herein-before described.
In witness whereof, I, the said Franz Jaburek, have hereunto set my
hand and seal, this Eighth day of August, in the year of our Lord 1
One thousand eight hundred and sixty.
Witness,
WILLIAM LEVERTON.
