THE MANUFACTURE OF AN ACID FOR IMPROVING ORDINARY VINEGARS, OR TO BE USED AS A SUBSTITUTE FOR VINEGARS, AND FOR OTHER PURPOSES."
Year: 1881

page_text: LETTERS PATENT to William John Cooper, of Westminster Chambers, in the
City of Westminster, for an Invention of "THE MANUFACTURE OF AN ACID
FOR IMPROVING ORDINARY VINEGARS, OR TO BE USED AS A SUBSTITUTE FOR
VINEGARS, AND FOR OTHER PURPOSES."
PROVISIONAL SPECIFICATION left by the said William John Cooper at
the Office of the Commissioners of Patents on the 27th January 1881.
WILLIAM JOHN COOPER, of Westminster Chambers, in the City of Westminster.
"THE MANUFACTURE OF AN ACID FOR IMPROVING ORDINARY VINEGARS, OR TO
BE USED AS A SUBSTITUTE FOR VINEGARS AND FOR OTHER PURPOSES."
This Invention consists in improvements in the manufacture of phosphoric acid,
the process employed being sufficiently economical to permit of its use for
improving ordinary vinegars or as a substitute for the same and for other purposes.
The said acid whilst possessing most of the useful and essential properties of
ordinary vinegars, such as wine vinegar, malt vinegar, and white vinegar, also.
possesses additional advantages, inasmuch as it does not coagulate albumen, it
prevents the generation of vinegar eels, and destroys the latter when they exist in
ordinary vinegar; the corrosive action of the same on iron and silver is less than
that of the acids contained in ordinary vinegars, and at the same time the said acid.
is extremely wholesome, and is therefore especially valuable for alimentary and
medicinal purposes.
In order to manufacture phosphoric acid in accordance with this Invention I
take phosphate of lime and sulphuric acid in about equal proportions and mix
them together, adding thereto a convenient quantity of water as will be well
understood. By these means I obtain sulphate of lime as a powder and a dilute
solution of phosphoric acid. I then filter to separate the sulphate of lime and the
filtrate will be a solution of dilute phosphoric acid, the strength of which, as will
be readily understood, depending upon the relative quantity of water added as
hereinbefore mentioned. The solution of dilute phosphoric acid is the substitute
for ordinary vinegars above referred to.
Ordinary vinegars will be greatly improved by the addition of a quantity of the
said phosphoric acid.
I have also found that a very pleasant and beneficial beverage can be prepared
from the said acid by adding thereto carbonic acid gas by any ordinary means,
as will be well understood, with the addition when desired of any suitable flavoring
or coloring material.

· Ordinary vinegars will be greatly improved by the addition of a quantity of the
said phosphoric acid.
I have also found that a very pleasant and beneficial beverage can be prepared
from the said acid by adding thereto carbonic acid gas by any ordinary means, as
will be well understood, with the addition when desired of any suitable flavoring
or coloring material.
Having thus described and ascertained the nature of my said Invention, and
the manner in which it is to be performed, I would observe in conclusion that
what I consider novel and original, and therefore claim as. constituting the
Invention secured to me by the said herein before in part recited Letters Patent
is,―
The manufacture of phosphoric acid, substantially as and for the purposes herein-
before described and set forth.
In witness whereof, I, the said William John Cooper, have hereunto set my
hand and seal, this Twenty seventh day of July, in the year of our Lord
One thousand eight hundred and eighty one.
