AN IMPROVED COMPOSITION OR PRE- PARATION FOR SIZING COTTON, LINEN, OR WOOLLEN YARNS, AND OTHER SIMILAR
Year: 1866

page_text: LETTERS PATENT to George Haworth, Manager, Thomas Parrington,
Tape Sizer, and William Hudson, Joiner, all of Preston, in the County
of Lancaster, for the Invention of "AN IMPROVED COMPOSITION OR PRE-
PARATION FOR SIZING COTTON, LINEN, OR WOOLLEN YARNS, AND OTHER SIMILAR
Sealed the 19th June 1866, and dated the 6th March 1866.
PROVISIONAL SPECIFICATION left by the said George Haworth, Thomas
Parrington, and William Hudson at the Office of the Commissioners
of Patents, with their Petition, on the 6th March 1866.
We, GEORGE HAWORTH, Manager, THOMAS PARRINGTON, Tape Sizer, and
WILLIAM HUDSON, Joiner, all of Preston, in the County of Lancaster, do
hereby declare the nature of the said Invention for "AN IMPROVED COMPOSITION
OR PREPARATION FOR SIZING COTTON, LINEN, OR WOOLLEN YARNS, AND OTHER SIMILAR
SUBSTANCES," to be as follows:-
This Invention consists of a composition or preparation for the sizing of
cotton, linen, or woollen yarns, and similar substences. In the sizing of
cotton, linen, or woollen yarns, the composition or preparation generally used
or employed is a mixture of flour, water, tallow, and soft soap. Now our

page_text: Invention consists in adding to the ordinary size preparation or composition
a portion of caustic soda or ash in the following proportions :-To every two
hundred and fifty-five pounds of ordinary preparation or composition we add
one and a half pounds of caustic soda. The advantages obtained by this
Invention are, the cloth will always weave softer and better than with any
other preparation now in-use, it will never mildew, it may be used much
thinner and still have the same weight, and the cloth will not be subject to
those brown stiff places which are frequently caused through the frequent
stopping of the sizing machine. We do not confine ourselves to the quantities
herein-before given as they may be varied as circumstances may require.
Another advantage we obtain by using the above caustic soda or ash is that
we can produce the above results with one half the amount of tallow and
Soap.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Haworth, Thomas Parrington, and William Hudson
in the Great Seal Patent Office on the 4th September 1866.
TO ALL TO WHOM THESE. PRESENTS SHALL COME, we, GEORGE
HAWORTH, Manager, THOMAS PARRINGTON, Tape Sizer, and WILLIAM HUDSON,
Joiner, all of Preston, in the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of March, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said George Haworth, Thomas Parrington, and William Hudson, Her
special licence that we, the said George Haworth, Thomas Parrington, and
William Hudson, our executors, administrators, and assigns, or such others
as we, the said George Haworth, Thomas Parrington, and William Hudson,
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 "AN IMPROVED COM-
POSITION OR PREPARATION FOR SIZING COTTON, LINEN, OR WOOLEN YARNS, AND
OTHER SIMILAR SUBSTANCES," upon the condition (amongst others) that we, the said
George Haworth, Thomas Parrington, and William Hudson, cur executors or
administrators, by an instrument in writing under our, or their, or one of

page_text: 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 George Haworth, Thomas Parrington,
and, William Hudson, 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:-
The ordinary composition or preparation for sizing purposes consists of a
mixture of flour, water, tallow, and soft soap, after it has been fermented.
Our Invention consists in the addition to these ingredients, but used in
somewhat different proportions, of a portion of caustic soda or caustic potash,
but the same is not to be applied unless and until the flour has gone through
the process of fermentation. Our improved composition is and should be
prepared in the following manner:-Take two hundred and forty pounds of
flour, mix and ferment the same with water in the usual manner, then take
ten pounds of tallow, five pounds of soft soap, one gallon of water, and half
a gallon of the liquid formed by dissolving caustic soda or potash in soft
water in the proportions of two pounds of soda or ash to half a gallon of
water, and mix and boil together such last-named ingredients by steam or
fire, and when they are quite dissolved, pour the mixture into the above-
mentioned mixture of flour, and the two when stirred well together are ready
for use, and form our improved composition.
The advantages of our Invention are as follows:-
First, the great saving of tallow, soft soap, and other such like softening
ingredients required in the making of size.
Second, the sizing frame does not require stoping so often, thereby pre-
venting the hard stiff brown places on the yarn.
Third, a great saving is effected in healds, and the yarn when thus sized
weaves much softer, produces cloth of a superior quality, and not subject to
milldew.
We do not confine ourselves to the proportions herein specified, as these
may and will have to be varied according to the nature of the goods intended
to be sized, as practical sizers will at all times fully understand. We believe
that caustic soda or caustic potash has never been used in the preparation of
size after the flour has gone through the fermentation process; we therefore
claim the sole right to make, use, and vend this improved composition or
preparation as herein-before specified.

page_text: We likewise claim the sole right of using and selling for use in making
size these ingredients if added after fermentation.
In witness whereof, we, the said George Haworth, Thomas Parrington,
and William Hudson, have hereunto set our hands and seals, this
day of June, One thousand eight hundred and sixty-six.
