Im- PROVEMENTS IN THE MANUFACTURE OF SILK CRAPE
Year: 1874

page_text: LETTERS PATENT to Robert Henry Kay and Alfred Thomas Richardson,
of the Firm of Kay and Richardson, of 39, Gutter Lane, in the
City of London, Crape Manufacturers, for the Invention of "Im-
PROVEMENTS IN THE MANUFACTURE OF SILK CRAPE."
Sealed the 2nd April 1874, and dated the 30th January 1874.
PROVISIONAL SPECIFICATION left by the said Robert Henry Kay
and Alfred Thomas Richardson at the Office of the Commissioners
of Patents, with their Petition, on the 30th January 1874.
We, ROBERT HENRY KAY and ALFRED THOMAS RICHARDSON, of the
Firm of Kay and Richardson, of 39, Gutter Lane, in the City of London,
Crape Manufacturers, do hereby declare the nature of the said In-
vention for "IMPROVEMENTS IN THE MANUFACTURE OF SILK CRAPE," to be as
follows:-
In manufacturing silk crape it has hitherto been customary to use a
fabric made of raw silk thrown with a certain amount of twist. Now
our Invention consists in making a fabric of the silk commonly called.
"spun silk," including the different varietics known as Galletta,.

page_text: Schappe, and other descriptions of spun silk, either discharged or
undischarged. These varieties of spun silk are first spun in the ordinary
manner, both in single and twofold, and then we impart an extra
amount of twist in a throstle spinning frame to the yarns, either in
water or not. The yarns so prepared are woven in an ordinary loom,
either alone or in combination with other silks or cotton or other fibrous
materials. The fabric when woven is then subjected to the usual
operations of crimping and finishing.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Robert Henry Kay and Alfred Thomas Richardson
in the Great Seal Patent Office on the 25th July 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ROBERT
HENRY KAY and ALFRED THOMAS RICHARDSON, of the Firm of Kay
and Richardson, of 39, Gutter Lanc, in the City of London, Crape
Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of January, in the year
of our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Robert Henry Kay and Alfred Thomas
Richardson, Her special licence that we, the said Robert Henry
Kay and Alfred Thomas Richardson, our executors, administrators, and
assigns, or such others as wc, the said Robert Henry Kay and Alfred
Thomas Richardson, our 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 SILK CRAPE," upon the
condition (amongst others) that we, the said Robert Henry Kay and
Alfred Thomas Richardson, our executors or administrators, by an instru-
ment in writing under our, or their, or one of our or their hands and seals,
should particularly describe and ascertain the nature of the said In-
vention, 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

page_text: calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that we, the said Robert Henry Kay and Alfred
Thomas Richardson, do hereby declare the nature of our 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) :-
66
In manufacturing silk crape it has hitherto been customary to use a
fabric made of raw silk thrown with a certain amount of twist. Now
our Invention consists in making a fabric of the silk commonly called
spun silk," including the different varieties known as Galletta,
Schappe, and other descriptions of spun silk, either discharged or
undischarged. These varieties of spun silk aro first spun in the ordinary
manner, both in single and twofold, and then we impart an extra
amount of twist in a throstle spinning frame to the yarns, either in
water or not. The yarns so prepared are woven in an ordinary loom,
either alone or in combination with other silks or cotton or other fibrous
materials. The fabric when woven is then subjected to the usual
operations of crimping and finishing.
Having thus stated the nature and particulars of our Invention we
wish it to be understood that we make no claim to any of the machinery
employed in the various operations of spinning, weaving, crimping, and
finishing crape, but what we do claim is the use of "spun silk" in the
manufacture of silk crape, in the manner described.
In witness whereof, we, the said Robert Henry Kay and Alfred
Thomas Richardson, have hereto set our hands and seals, this
twenty-fourth day of July, One thousand eight hundred and
seventy-four.
