page_text: substances or materials for the purpose of stiffening them. From
the experiments hitherto made I find that about four ounces of tho
mustard or other vegetable antiseptic oil to ono gallon of size is
sufficient, but tho proportions must be varied according to the strength
of the size and the quality of the fabrics.
SPECIFICATION in pursuance of the conditions of the Letters Patent,

Her special licence that I, the said Robert Kay Whitehead, my

should at any time agree with, and no others, from time to time 2
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 Islo
of Man, an Invention for “IMPROVEMENTS IN THE MANUFACTURE OF SIZE,"
upon the condition (amongst others) that I, the said Robert Kay 2
Whitehead, 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 tho
samo to be filed in the Great Scal Patent Office within six calendar 3
months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Robert Kay Whitehead, do hereby
declare the nature of my said Invention, and in what manner the

page_text: samo is to be performed, to be particularly described and ascertained
in and by the following statement (that is to say) :-
The nature of my Invention consists in combining mustard oil or
other vegetablo oil possessing similar autiseptic properties with farin-
accous or other sizo in order to prevent mildew in the yarns, woven
fabrics, and other fibrous substances or materials that have been
operated upon with the improved size.
•
In performing my Invention I find that about four ounces of tho
mustard or other vegetable antiseptic oil mixed and boiled with one
gallon of the ordinary farinaceous or other size produce a good result,
but the proportions must be varied according to the strength of the
size, tho quality and nature of the fabrics, and the nature of the sizing,
stiffening, and filling to bo imparted to the yarn, woven fabric, or other
fibrous substance or material under operation.
"
Having thus stated the nature of my Invention, and described the
manner of performing, I declare that I claim as my improvements
in the manufacturo of size the combination of mustard oil or other
vegetable oil possessing similar antiseptic properties with farinaceous
or other sizo, for preventing mildew.
In witness whereof, I, tho said Robert Kay Whitehead, havo
hereto set my hand and scal, this Nineteenth day of August
One thousand eight hundred and soventy-three.
