Year: 1867

page_text: LETTERS PATENT to Frederic Pelham Warren, of East Court, Cosham,
in the County of Hants, Commander in the Royal Navy, for the Invention
of "IMPROVEMENTS IN TOBACCO PIPES."
Sealed the 12th November 1867, and dated the 17th May 1867..
PROVISIONAL SPECIFICATION left by the said Frederic Pelham Warren
at the Office of the Commissioners of Patents, with his Petition, on the
17th May 1867.
I, FREDERIC PELHAM WARREN, of East Court, Cosham, in the County of
Hants, Commander in the Royal Navy, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN TOBACCO PIPES," to be as follows:-
This Invention has for its object improvements in tobacco pipes, and consists
in so arranging such pipes as that the smoke after passing down through the
interior of the bowl or chamber containing the tobacco is caused to come in
contact with the outer surface of such bowl or chamber, or to pass through or
along a suitable passage or channel, or passages or channels, in such manner
as to be acted upon and dried or deprived of its essential oil and other moisture
by the heat emanating from the bowl or chamber in which the tobacco is
being burnt.
According to my Invention I form or connect the stem of the pipe with the'
bowl thereof near the upper part or rim of the latter, and I form the bowl
with a second bowl or internal chamber, so arranged as to leave an annular or
other space or chamber between itself and the outer bowl or chamber. A
suitable opening or passage, or openings or passages is or are provided in the
lower part of the inner bowl, thus affording a communication or communica-

page_text: tions between it and the annular or other space or chamber before. referred to.
It will hence be understood that the smoke from the burning tobacco is drawn
down through the opening or passage, or openings or passages, of the inner bowl
into the annular or other space or chamber, in which latter it ascends into
and along the stem of the pipe, and that while so ascending in the annular or
other space the smoke is dried or deprived of its moisture by contact with the
heated outer surface of the inner bowl. So much of the moisture emanating
from the tobacco and smoke as is not evaporated by the contact of the latter
with the heated surface or surfaces before referred to collects in the lower
part of the annular or other space or chamber, by preference between the
lower parts of the inner and outer bowls,
In other cases I dispense with the inner bowl or chamber, and form or
construct the outer bowl with a passage or passages leading from the lower
part of the interior of the bowl up to the top of the rim, where I employ a
plug or plugs which may be readily withdrawn when it is desired to clean the
passage or passages. The stem of the pipe communicates with the passage
or passages referred to at a point far removed from the bottom or base of the
bowl, so that the smoke is drawn up the passage or passages in the side of
the bowl, and in its passage through it or them to the stem is acted upon
and dried by the heat emanating from the burning tobacco within the
bowl:
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Frederic Pelham Warren in the Great Seal Patent Office
on the 15th November 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERIC
PELHAM WARREN, of East Court, Cosham, in the County of Hants, Commander
in the Royal Navy, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of May, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Frederic Pelham Warren, Her, special license, that I, the said Frederic
Pelham Warren, my executors, administrators, and assigns, or such others as
I, the said Frederic Pelham Warren, 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

page_text: 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
"IMPROVEMENTS IN TOBACCO PIPES," upon the condition (amongst others) that
I, the said Frederic Pelham Warren, 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 Frederic Pelham Warren, do hereby
declare the nature of my said 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 has for its object improvements in tobacco pipes, and consists:
in so arranging such pipes as that the smoke after passing down through the
interior of the bowl or chamber containing the tobacco is caused to come
in contact with the outer surface of such bowl or chamber, or to pass through
or along a suitable passage or channel, or passages or channels in such manner
as to be acted upon and dried or deprived of its essential oil and other moisture
by the heat emanating from the bowl or chamber in which the tobacco is
being burnt.
According to my Invention I form or connect the stem of the pipe with the
bowl thereof near the upper part or rim of the latter, and I form the bowl
with a second bowl or internal chamber, so arranged as to leave an annular
or other space or chamber between itself and the outer bowl or chamber. A
suitable opening or passage, or openings or passages, is or are provided in the
lower part of the inner bowl, thus affording a communication or communica-
tions between it and the annular or other space or chamber before referred to.
It will hence be understood that the smoke from the burning tobacco is drawn
down through the opening or passage, or openings or passages, of the inner
bowl into the annular or other space or chamber, in which latter it ascends
into and along the sten of the pipe, and that while so ascending in the
annular or other space the smoke is dried or deprived of its moisture by
contact with the heated outer surface of the inner bowl. So much of the
moisture emanating from the tobacco and smoke as is not evaporated by the
contact of the latter with the heated surface or surfaces before referred; to
collects in the lower part of the annular or other space or chamber, bý
preference between the lower parts of the inner and outer bowls.
-
In other cases I dispense with the inner bowl or chamber, and form or
*

page_text: construct the outer bowl with a passage or passages leading from the lower
part.of the interior of the bowl up to the top of the rim, where I employ a
plug or plugs which may be readily withdrawn when it is desired to clean the
passage or passages. The stem of the pipe communicates with the passage
or passages referred to at a point: far removed from the bottom or base of
the bowl, so that the smoke is drawn up the passage or passages in the
side of the bowl, and in its passage through it or them to the stem is acted
upon and dried by the heat emanating from the burning tobacco within
the bowl.
.
The manner in which 'my said Invention may be conveniently carried into
effect will be fully understood from the following description, aided by
reference to-the-Sheet of Drawings accompanying this Specification, in which
Fig. 1 represents a vertical section of a pipe constructed with an inner bowl a
and an external bowl.b, according to my Invention, and having the junction
of the stem c with-the external bowl b at a point as near the top edge of the
latter as practicable, so that the smoke from the burning tobacco in the inner
bowl-a after being drawn down through the hole d into the annular space e
between the two bowls ascends in such annular space, and in its passage. to
the stem cis dried or deprived of its moisture by contact with the heated
outer surface of the inner bowl a, the lower part of the outer bowl b affording
space for the collection of such moisture as is not evaporated by contact with
the said heated surface.

It will be seen that in the present modification the stem of the pipe is
formed in one piece with the outer bowl, and that a ring of suitable material f
(preferring layers of cork and felt combined) is secured around the upper part
of the exterior of the inner bowl a to make it fit accurately and readily into
the upper part of the bowl b, and yet render it capable of instant removal,
either for the purpose of removing moisture from the bottom of the bowl bor
for other purposes.

Fig. 2 represents a pipe similar in. construction to that shewn in Fig. 1,
with the exception that in the present instance the. pipe, is arranged to be
used in combination with a separate or loose stem..
Fig. 3 represents a pipe, in which, the inner bowl a has several holes d
through its lower part, and is permanently secured to the external bowl b
instead of being capable of removal, as in the modifications previously described:
In the present instance an.opening is formed through the lower part of the
external bowl for the purpose of emptying any moisture that may collect there,
and this opening is closed by an ornamental plug g having a ring composed
of cork and felt, as aforesaid, or other suitable material, round it, as shewn in

page_text: black to make it fit tightly without being troublesome to remove.
This pipe
is arranged for a loose or separate stem, such as a goose bone, having an
ordinary cork or other suitable packing at its end as shewn.
Fig. 4 is a vertical section, and Fig. 5 a horizontal section (through the
line A, B, of Fig. 4) of a modification of double bowl pipe, preserving the
external appearance of the ordinary pipe, but so arranged, nevertheless, as to
comply with the main object of my Invention; the smoke in this case passing
up around the outer surface of the inner bowl a, and on reaching the upper
part of the annular space entering and going down a passage h formed in the
side of the outer bowl and leading to the stem of the pipe as shewn.
Fig. 6 is a sectional view of a pipe, in which the inner bowl or chamber a
is dispensed with, a passage i leading from the lower part of the interior of the
bowl up to the upper part of the same, at or near which point the passage in
question communicates with the pipe stem. The passage i is closed at top by
a small plug k, and the stem is made in one piece with the bowl.
Having thus described the nature of my said Invention, and in what manner
the same may be conveniently carried into effect, I would have it understood
that I do not confine or limit myself to the precise forms or details represented,
as the same are susceptible of various modifications without departing from
the distinguishing features of my Invention, with reference to which I claim,
the construction and arrangement of tobacco pipes in such manner as that the
smoke after passing down through the interior of the bowl or chamber con-
taining the tobacco is caused to come in contact with the outer surface of
such bowl or chamber, or to pass through or along a suitable passage or
channel, or passages or channels (continued to the top of the bowl and closed
by a plug or plugs) in such manner as to be acted upon and dried or deprived
of its essential oil and other moisture by the heat emanating from the bowl
or chamber in which the tobacco is being burnt, substantially as herein-before
described and shewn in the accompanying Sheet of Drawings.
I also claim the rings composed of cork and felt as described.
In witness whereof, I, the said Frederic Pelham Warren, have here-
unto set my hand' and seal, this Fifteenth day of November, in the
year of our Lord One thousand eight hundred and sixty-seven
FREDERIC PELHAM WARREN. (L.S.)
