the Invention of 1 Two
IN TUR MANURACTURE OR SIZE "
Sealed the 8th February 1870, and dated the 11th August 1869.
PROVISIONAL SPECIFICATION left by the said Christopher Crossley,
Robert Whipp, and Thomas Crossley at the Office of the Com-
missioners of Patents, with their Petition, on the 11th August 1869.
We, CHRISTOPHER CROSSLEY and ROBERT WHIPP, both of Manchester,
in the County of Lancaster, Drysalters, and THOMAS CROSSLEY, of
Rochdale, in the same County, Manufacturing Chemist, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE
MANUFACTURE OF SIZE," to be as follows:-
Our Invention consists in the application of a new composition in
the manufacture of size, by which the yarns or warps are dressed

page_text: or prepared for weaving, and the fabric produced is improved in
appearance and quality and rendered impervious to mildew.
In performing our Invention we dissolve spelter in muriatic acid, the
muriate of zine so prepared is then boiled with sulphate of aluminum.
The acid left in this composition may be neutralised by soda or other
alkali. We wish to observe that the above ingredients have been found
by experiments to give good results, but other ingredients possessing
similar properties may be used.
The improved composition above described is added to and boiled
with any farinaceous or other size, such as is now employed for sizing
cotton, woollen, and other yarns and fabrics.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Christopher Crossley, Robert Whipp, and Thomas
Crossley in the Great Seal Patent Office on the 9th February
1870.
TO ALL. TO WHOM THESE PRESENTS SHALL COME, we, СHRIS-
TOPHER CROSSLEY and ROBERT WHIPP, both of Manchester, in the
County of Lancaster, Drysalters, and THOMAS CROSSLEY, of Rochdale, in
the same County, Manufacturing Chemist, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of August, in the of
year
our Lord One thousand eight hundred and sixty-nine, in the thirty-third
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said Christopher Crossley, Robert Whipp, and Thomas
Crossley, Her special licence that we, the said Christopher Crossley,
Robert Whipp, and Thomas Crossley, our executors, administrators; and
assigns, or such others as we, the said Christopher Crossley, Robert
Whipp, and Thomas Crossley, 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 SIZE,"

page_text: upon the condition (amongst others) that we, the said Christopher
Crossley, Robert Whipp, and Thomas Crossley, our executors or adminis-
trators, by an instrument 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 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 we, the said Christopher Crossley, Robert
Whipp, and Thomas Crossley, 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) -
:-
Our Invention consists in applying a preparation of zine for the
production of a new composition to be used in the manufacture of size
for sizing and dressing yarns or warps in order to improve the appearance
and quality of the fabrics woven with the yarn or warp prepared with
our improved size, and to render them impervious to mildew.
In performing our Invention we dissolve spelter in muriatic acid
to obtain muriate of zinc, and in order to obtain this muriate of the
desired strength we charge the muriatic acid with spelter until it has
absorbed as much as it will hold in solution. The muriate of zinc may
then be boiled with sulphate of alumina, and if it should be found
desirable the acid left in the composition may be neutralized by soda
or other alkali. The muriate of zinc so prepared is added to and boiled
with any farinaceous or other size such as is now employed for sizing
cotton, woollen, and other yarns and fabrics, in the proportion of from
twenty-five to thirty pounds of the muriate of zinc to from two hundred
and forty to two hundred and eighty pounds of flour or other size.
Having thus stated the nature of our Invention, and described the
mode of performing the same, we wish to observe that we do not intend
to limit ourselves to the proportions given, as they may be varied
according to the strength of the muriate of zinc and to the nature
or quality of the farinaceous or other size with which it is to be
combined, and to the quality of the yarn or other material to be sized;
but what we claim as our Invention is, the application of muriate

page_text: of zinc either alone or in combination with other substances in the
manufacture of size.
In witness whereof, we, the said Christopher Crossley, Robert
Whipp, and Thomas Crossley, have hereto set our hands and
seals, this. Eighth day of February, One thousand eight hundred
and seventy.
