IMPROVEMENTS IN THE MANUFACTURE OF TOBACCO PIPES
Year: 1860

page_text: LETTERS PATENT to James Langstein, of Charing Cross, in the County
of Middlesex, Tobacconist, for the Invention of "IMPROVEMENTS IN THE
MANUFACTURE OF TOBACCO PIPES
"
Sealed the 27th September 1860, and dated the 27th March 1860.
PROVISIONAL SPECIFICATION left by the said James Langstein at the
Office of the Commissioners of Patents, with his Petition, on the 27th
March 1860.
I, JAMES LANGSTEIN, of Charing Cross, in the County of Middlesex,
Tobacconist, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN THE MANUFACTURE OF TOBACCO PIPES," to be as follows:-
I take carbonate of magnesia & pipeclay in about equal quantities, and
having first thoroughly dried the pipeclay, I pulverize and reduce them both
to powder; I then sift and mix them intimately together. Having thoroughily
mixed and combined the magnesia and pipeclay, I mix them with a sufficient
quantity of water to form a plastic mass of a consistency suitable for moulding;
I then mould and form this mixture into pipes in the ordinary manner of
making clay pipes, after which they are dried & baked, or fired in like manner
to ordinary clay pipes. When the pipes are so far finished, I dip them in a
weak solution of silicate of soda. Pipes so manufactured are very light, and
possess very absorbent qualities.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
LANGSTEIN, of Charing Cross, in the County of Middlesex, Tobacconist, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh 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
James Langstein, Her special licence that I, the said James Langstein, my
executors, administrators, and assigns, or such others as I, the said James
Langstein, 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 "IMPROVEMENTS IN THE
MANUFACTURE OF TOBACCO PIPES," upon the condition (amongst others) that
I, the said James Langstein, my executors or administrators, by an instru-
ment 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 im-
mediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said James Langstein, 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
(that is to say):-
My Invention of improvements in the manufacture of tobacco pipes relates
to the combination of materials of which I form those articles, the object
being to produce, a pipe possessing great advantages for smoking purposes.
Pipes made as hereinafter described are highly absorbent of the essential oils
of tobacco, and indeed pervious thereto, as the oils absorbed in smoking
tobacco pass through and exude from the exterior of the pipe.
To carry out this manufacture, I take carbonate of magnesia and pipeclay
in about equal quantities, & having first thoroughly dried the pipeclay, I
pulverize and reduce them both to powder; I then sift and mix these
materials intimately together. Having thoroughly mixed and combined the

page_text: magnesia and pipeclay, I mix them with a sufficient quantity of water to form
a plastic mass of a consistency suitable for moulding; I then mould and form
this mixture into pipes in the ordinary manner of moulding and making clay
pipes. Pipes so formed are subsequently dried and baked or fired in the
same manner as ordinary clay pipes. When the pipes are so far finished, I
dip them in a weak solution of silicate of soda, using silicate of soda of com-
merce diluted with about three times its volume of water. This solution imparts
the necessary strength to the pipe. Pipes so manufactured are very light,
and possess at same time strength and the absorbent qualities desired.
Having described the nature of my Invention, and the manner of per-
forming the same, I declare that what I claim, as my Invention to be pro-
tected by the herein-before in part recited Letters Patent, is the manufacture
of tobacco pipes of carbonate of magnesia and pipeclay, and immersing such
manufacture in a weak solution of silicate of soda, as herein-before described.
In witness whereof, I, the said James Langstein, have hereunto set my
hand and seal, this Twenty-sixth day of September, in the year of our
Lord One thousand eight hundred and sixty.
J. LANGSTEIN. (L.S.)
