Year: 1867

page_text: LETTERS PATENT to Leopold Beral Bertram, of Duncan Villa, Redland,
in the County of Gloucester, for the Invention of "AN IMPROVED TOBACCO
PIPE."
Sealed the 12th May 1868, and dated the 15th November 1867.
PROVISIONAL SPECIFICATION left by the said Leopold Beral Bertram
at the Office of the Commissioners of Patents, with his Petition, on
the 15th November 1867.
I, LEOPOLD BEBAL BERTRAM, of Duncan Villa, Redland, in the County of
Gloucester, do hereby declare the nature of the said Invention for "An
IMPROVED TOBACCO PIPE," to be as follows:-
The object of my Invention is the construction of a pipe, wherein the smoke
is separated from the tobacco oil and nicotine before it passes from the bowl to
the stem of the said pipe in order to prevent the injurious effects so frequently
experienced by smokers in using pipes of ordinary construction.
The said Invention consists chiefly in providing the bowl of the pipe with
an interior cup which is perforated at the bottom to communicate with a
space in the lower part of the bowl, and is provided with a flange or number
of flanges to intercept the oil and nicotine and retain them in the said space,
while the smoke is drawn into the stem through small apertures or per-
forations in the said flanges and through an annular space surrounding
the cup, which space is closed by a flange or collar at the top of the bowl.
If desired a flange may also be formed around the inside of the bowl.

page_text: The bowl of my improved pipe may be made of clay, meerschaum, wood, or
other well-known materials, and of any desired form or configuration. The
interior cup is preferably formed of ordinary pipe clay, and is of such a size
that when placed within the bowl the required annular space is left between
its upper part and the interior of the said bowl, and also between the bottom
of the said cup and the part of the bowl below the intercepting flange. One
or any desired number of holes may be formed through the bottom of the said
cup into this lower space. In practice I prefer to provide the cup with only
one of the intercepting flanges which is formed near the bottom of the said
cup, and is made to fit closely all around the interior of the bowl, so that no
oil or other liquid can rise by capillary attraction or can be drawn between
the said bowl and flange; the upper surface of this flange may be countersunk
to retain any liquid that may be formed above the saine by condensed vapour
or otherwise. The flange is preferably perforated with four small holes, but
may have a greater or less number if desired, or may be formed with notches
instead of holes. I also prefer to form the top of the interior cup with a
flange or rim of the same diameter as the exterior of the bowl, and to fit the
two together in such a manner that they present a neat and uniform appear-
ance. The cup may also be formed with a ring or collar near the top to fit
the interior of the bowl and hold the cup securely therein, or the said cup
may be made taper from the intercepting flange upward, the top being of the
same diameter as the interior of the bowl. The latter is provided with a small
socket or aperture to receive the stem which may be attached to the bowl
anywhere between the top of the cup and the intercepting flange. The stem
may also be formed solidly or in one piece with the bowl.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Leopold Beral Bertram in the Great Seal Patent Office on
the 15th May 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LEOPOLD
BERAL BERTRAM, of Duncan Villa, Redland, in the County of Gloucester,
:send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of November, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirty-first year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said Leopold Beral Bertram, Her special licence that I, the said Leopold Beral

page_text: Bertram, my executors, administrators, and assigns, or such others as I, the
said Leopold Beral Bertram, my executors, administrators, and assigns, should.
at any time agree with, and no others, from time to time and 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 TOBACCO PIPE," upon the condition (amongst others) that I, the said
Leopold Beral Bertram, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should particu-
larly 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Leopold Beral Bertram, 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, reference being had to the accompanying Sheet of Drawings,
forming a part of this Specification
:-
The object of my Invention is the construction of a pipe, wherein the
smoke is separated from the tobacco oil and nicotine before it passes from the
bowl to the stem of the said pipe in order to prevent the injurious effects upon
the health so frequently experienced by smokers in using pipes of ordinary
construction.
The said Invention consists chiefly in providing the bowl of the pipe with.
an interior cup, which is perforated at the bottom to communicate with a
space in the lower part of the bowl, and is provided with a flange or number.
of flanges to intercept the oil and nicotine and retain them in the said space,
while the smoke is drawn into the stem through small apertures or perfora-.
tions in the said flanges, and through an annular space surrounding the eup,
If desired
which space
is closed by a flange or collar at the top of the bowl.
the perforated flange may be formed around the inside of the bowl instead of
upon the cup, or may be made separately or detached, and inserted between-
the cup and bowl.

The bowl a of my improved pipe may be made of clay, meerschaum, wood,
or other well-known materials, and may be of any desired form or configu-
ration. The interior cup 6 is preferably formed of ordinary pipe clay, and is
of such a size that when placed within the bowl a the required annular space c
is left between its upper part and the interior of the said bowl. The space c
must also be left between the bottom of the said cup and the part of the bowl
below the intercepting flange d. A hole or any desired number of such
boles may be made through the bottom of the cup 6 to form a communication
between the interior of the said cup and this lower space. In practice I
prefer to provide the cup 6 with only one of the intercepting flanges & which
is formed near the bottom of the said cup, and is made to fit closely all around
the interior of the bowl a, so that no oil or other liquid can rise by capillary
attraction, or can be drawn between the said bowl and the flange d; the
upper surface of this flange may be countersunk to retain any liquid that may
be formed above the same by condensed vapour or otherwise. The flange dis
preferably perforated with four of the small holes f, but may have a greater
or less number if desired, or may be formed with notches on its perimeter
instead of such holes. I also prefer to form the top of the cup b with a flange
or rim g of the same diameter as the exterior of the bowl a, and to fit the
two together in such a manner that the exterior of the flange g forms a con-
tinuation of the bowl, thus imparting to the latter a neat and uniform
appearance, as shewn in Figure 2. A screw thread H is preferably formed
just below the flange 9, and a corresponding screw thread is formed at the top
of the bowl a. This mode of securing the cup in the bowl effectually and
closely unites the two parts, preventing any leakage between the top of the
said bowl and the flauge g, while it allows the cup to be readily removed
from the bowl when the latter requires emptying or cleaning. The cup 6 may
also be formed with a plain ring or collar near the top to fit the interior of
the top of the bowl a and hold the cup securely therein, or the said cup may
be made taper from the intercepting flange upward, the top of the cup being
of the same diameter as the interior of the bowl; the said bowl may be formed
solidly or in one piece with the stem i, as shewn, or may be provided with a
small socket or aperture to receive the stem, the latter may be formed on or
attached to the bowl anywhere between the bottom of the screw thread h and
the top of the intercepting flange d. As the tobacco in the cup 6 is consumed
the smoke and other products of combustion are drawn through the hole e, the
oil and nicotine which are so deleterious to the health being caught and
retained in the space c below the flange d while the smoke passes through the
perforations into the space c above the flange d and through the stem i
b

page_text: reaching the mouth of the smoker thoroughly purified of all its injurious
properties,
Having thus fully described my Invention, and shown how the same may
be conveniently and advantageously carried into practice, I wish it understood
that I do not claim or limit the application thereof to pipes with any par-
ticular shape or construction of the bowl, nor shape or length of stem, or
mode of securing the same to the bowl, as the said Invention may be applied
to pipes of any ordinary shape and construction, and also to cigar holders,
neither do I claim the use of a cup placed within the bowl and communi-
cating therewith by means of a hole or perforation in the bottom of the cup;
but I claim separating the lower portion of the space enclosed between the
bowl and cup from the upper portion of such space by means of a perforated
or notched flange or collar, or number of such flanges, and arranging the stem
to communicate with the enclosed space above the said flange or flanges, for
the purposes set forth.
In witness whereof I, the said Leopold Beral Bertram, have hereunto
set my hand and seal, this Twelfth day of May, in the year of our
Lord One thousand eight hundred and sixty-eight.
LEOPOLD BERAL BERTRAM. (L.B.)
