AN IMPROVEMENT IN PIPES FOR SMOKING
Year: 1868

page_text: LETTERS PATENT to Adolph Strauss, of Basinghall Street, in the
City of London, Merchant, for the Invention of "AN IMPROVEMENT
IN PIPES FOR SMOKING."
Sealed the 6th November 1868, and dated the 7th May 1868.
PROVISIONAL SPECIFICATION left by the said Adolph Strauss at
the Office of the Commissioners of Patents, with his Petition, on
the 7th May 1868.
I, ADOLPH STRAUSS, of Basinghall Street, in the City of London,
Merchant, do hereby declare the nature of the said Invention for "AN
IMPROVEMENT IN PIPES FOR SMOKING," to be as follows:-
In pipes made of meerschaum or other clay it is usual to insert a
plug which prevents the tobacco getting to the lower part of the bowl
of the pipe. The object of these plugs is to prevent the fire affecting
the lower part, which when so affected does not become colored. Now
my Invention is intended to dispense with these plugs and to form the
bowl itself in such manner that the lower part thereof becomes colored

page_text: notwithstanding that the tobacco is allowed to get to and burn at the
bottom of the bowl.
My improvement consists in forming the lower portion of the bowl
of considerably greater thickness than the upper portion, the increase
in thickness being preferably sudden and not gradual, in order that the 5
coloring may extend to the line of the increase. The increase in
thickness thus forms a circular ledge or shoulder about the middle of
the bowl.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Adolph Strauss in the Great Seal Patent Office
on the 7th November 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ADOLPH
STRAUSS, of Basinghall Street, in the City of London, Merchant, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Seventh day of May, in the year
of our Lord One thousand eight hundred and sixty-eight, in the thirty-
first year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Adolph Strauss, Her special licence
that I, the said Adolph Strauss, my executors, administrators, and
assigns, or such others as I, the said Adolph Strauss, 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 IMPROVEMENT IN
PIPES FOR SMOKING," upon the condition (amongst others) that I, the said
Adolph Strauss, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly 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.

page_text: NOW KNOW YE, that I, the said Adolph Strauss, 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 thereof, reference being had to the Drawing
hereunto annexed, that is to say :-
In pipes made of meerschaum or other clay it is usual to insert a
plug which prevents the tobacco getting to the lower part of the bowl
of the pipe. The object of these plugs is to prevent the fire affecting
the lower part, which when so affected does not become colored. Now
my Invention is intended to dispense with these plugs and to form the
bowl itself in such manner that the lower part thereof becomes colored
notwithstanding that the tobacco is allowed to get to and burn at the
bottom of the bowl.
My improvement consists in forming the lower portion of the bowl
of considerably greater thickness than the upper portion, the incrcaso
in thickness being preferably sudden and not gradual, in order that
the coloring may extend to the line of the increase. The increase in
thickness thus forms a circular ledge or shoulder about the middle of
the bowl.
The accompanying Drawing represents in section a pipe made
according to my Invention. It will be seen that the lower portion a
of the bowl is considerably thicker than the upper portion b. The
tobacco gets to and burns at the bottom or lower part c, but owing
to the greater thickness of the bowl at this part the fire does not affect
it and it becomes colored up to about the line d.
In witness whereof, I, the said Adolph Strauss, have hereunto set
my hand and seal, this Thirtieth day of October,. One thousand
