Year: 1864

page_text: LETTERS PATENT to Arthur Heald, of Sabden Whalley, in the County
of Lancaster, Cotton Spinner, for the Invention' of "AN IMPROVED
COMPOSITION FOR SIZING YARNS AND THREADS."
Sealed the 23rd September 1864, and dated the 29th March 1864.
PROVISIONAL SPECIFICATION left by the said Arthur Heald at the
Office of the Commissioners of Patents, with his Petition, on the 29th
March 1864.
I, ARTHUR HEALD, of Sabden Whalley, in the County of Lancaster, Cotton
Spinner, do hereby declare the nature of the said Invention for "AN IMPROVED
COMPOSITION FOR SIZING YARNS AND THREADS," to be as follows:-
In the sizing of yarns and threads the composition generally employed is a
mixture of flour, water, and tallow. Now my improved composition is
composed of a solution of chloride of barium, flour, water, and tallow, and
I prefer to prepare it as follows:-I mix the flour and water in the ordinary
manner, and just before the size is required for use I add as strong a solution
of chloride of barium, preferring this solution, as can be obtained, and boil this
mixture; the tallow is then added while the mixture is still hot. I find the
proportion of the solution of chloride of barium should vary from twenty to
sixty gallons to a sack of flour, according to the coarseness of the yarn or
thread and the weight of sized yarn or thread required.
