IMPROVEMENTS IN THE MANUFACTURE OF WHITING
Year: 1881

page_text: LETTERS PATENT to William Brothers, of Livesey Chemical Works, near
Blackburn, in the County of Lancaster, for an Invention of "IMPROVEMENTS
IN THE MANUFACTURE OF WHITING."
PROVISIONAL SPECIFICATION left by the said William Brothers at the
Office of the Commissioners of Patents on the 2nd November 1881.
"
WILLIAM BROTHERS, of Livesey Chemical Works, near Blackburn, in the
County of Lancaster. IMPROVEMENTS IN THE MANUFACTURE OF WHITING."
This Invention has for its object the manufacture of whiting of a superior
character and free from grit.
The Invention consists in mixing in suitable vessels caustic lime and water.
The vessels are furnished with arms, dashers, or other appliances, which when set
in motion thoroughly incorporate the atoms of lime with the water, and so
completely slake them. Ordinary furnace gases arising from the combustion of
coke, coal, or other substances yielding carbonic acid, or gases derived from other
sources containing a sufficient quantity of carbonic acid, are then pumped or forced
into the mixture through a hole or holes in or near the bottom of each of the
vessels. On the agitation of, the mixture and the introduction of the gases being
continued for two or three hours or other suitable time the lime becomes converted
into a carbonate of lime, and on the mixture being run off and dried a very
superior whiting is left as the residue. This carbonate of lime or whiting is
chemically fine, contains no grit, and is admirably adapted for all the purposes to
which whiting is applied.

_superior_whiting-is-left-as-the-residue. This carbonate of lime or whiting is
chemically fine, contains no grit, and is admirably adapted for all the purposes to
which whiting is applied.
Having now described and particularly set forth the nature of this Invention,
and the manner in which the same is or may be used or carried into effect, I would
observe in conclusion that I do not confine or restrict myself to the precise details
that I have, described or referred to, or to the adoption of any particular form of
apparatus for carrying out the foregoing process, as variations may be made therein
without deviating from the principles or main features of this Invention, but what
I consider to be novel and original and therefore claim as the Invention secured
to me by the herein before in part recited Letters Patent is, the manufacture of
whiting by the process herein before described.
In witness whereof, I, the said William Brothers, have hereunto set my hand
and seal, this Twenty-eight day of April, in the year of our Lord One
thousand eight hundred and eighty two.
WILLIAM BROTHERS. (L.S.)
