mohair and alpaca, or mohair and silk.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
FREDERICK HENSON, of New Cavendish Street, Portland Place, in the County
of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of November, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Frederick Henson, Her special licence that I, the said William
Frederick Henson, my executors, administrators, and assigns, or such others as
I, the said William Frederick Henson, 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 " CERTAIN
IMPROVED FABRICS MADE ENTIRELY OR PARTIALLY OF ALPACA OR MOHAIR," upon
the condition (amongst others) that I, the said William Frederick Henson,
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 inmediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said William Frederick Henson, do hereby
declare the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the follow-
ing statement thereof, that is to say :-
I manufacture a new fabric the back of which is formed of alpaca or mohair,
while the face is of silk. The two materials are united by any of the known
means for weaving or making compound fabrics. The silk facing may be
plain, or ribbed, or otherwise, or it may be woven into pile, terry, or velvet,
with or without the aid of wires.
I also manufacture velvet and terry and piled fabrics entirely of alpaca or
mobair, or of a mixture of alpaca and silk, or mohair, alpaca, and silk. The
process of manufacturing velvet or compound fabrics is so well known that it
is unnecessary to describe the same.

page_text: Having described the nature of my Invention, and in what manner the
same may be performed, I wish it to be understood that what I claim is,―
Firstly, the manufacture of fabrics the back of which is of alpaca or mohair,
or a mixture of alpaca and mohair with silk and other materials, and the face
of which is silk or satin faced, which may be either figured or plain.
Secondly, the manufacture of velvet the back of which is of alpaca or
mohair, or a mixture of either silk, alpaca, or mohair, and other materials,
while the pile is of silk.
Thirdly, the manufacture of velvets entirely of alpaca or mohair, or in
combination or mixed with silk or other materials.
In witness whereof, I, the said William Frederick Henson, have here-
unto set my hand and seal, this Eighth day of May, in the year of our
Lord One thousand eight hundred and sixty-one.
WILLIAM FREDERICK HENSON. (L.S.)
