Year: 1881

page_text: LETTERS PATENT to George Mander Allender, Managing Director of the
Aylesbury Dairy Company, Limited, of St. Petersburgh Place, Bayswater, in
the County of Middlesex, for an Invention of "AN IMPROVEMENT IN THE
PRESERVATION OF BUTTER”
PROVISIONAL SPECIFICATION left by the said George Mander Allender
at the Office of the Commissioners of Patents on the 26th May 1881.
GEORGE MANDER ALLENDER, Managing Director of the Aylesbury Dairy
Company, Limited, of St. Petersburgh Place, Bayswater, in the County of
Middlesex. 'AN IMPROVEMENT IN THE PRESERVATION OF BUTTER,"
"
This Invention relates to an improvement in the preservation of butter, founded
on that set forth in the Specification to Letters Patent, No. 2512, of 23rd June
1879, granted to Thomas Foster Wilkins, and consists in directly incorporating
orthophosphoric acid with the butter in a manner similar or generally similar to
that described in the said Specification for the admixture therewith of glacial
metaphosphoric acid.
Glacial metaphosphoric acid when in solution gradually becomes transformed
into orthophosphoric acid; further, it is admitted by all chemists that ortho-
phosphoric acid is absolutely inoccuous. I therefore propose to at once incorporate
orthophosphoric acid with the butter, intimately mixing, blending, and incorporating
it therewith by means of a butter-worker, or in any suitable manner.
The solution of orthophosphoric acid which I have found to answer well is, for
every one pound of butter twenty four grains of acid, dissolved in from one half to
one dram of water, which water I prefer should be distilled, but I do not propose
to limit myself to such proportions.

Company, Limited, of St. Petersburgh Place, Bayswater, in the County of
Middlesex. "AN IMPROVEMENT IN THE PRESERVATION OF BUTTER."
This Invention relates to an improvement in the preservation of butter, founded
on that set forth in the Specification to Letters Patent, No. 2512, of Twenty third
June 1879, granted to Thomas Foster Wilkins, and consists in directly incorporating
orthophosphoric acid with the butter in a manner similar or generally similar to
that described in the said Specification for the admixture there with of glacial
metaphosphoric acid.
Glacial metaphosphoric acid when in solution gradually becomes transformed into
orthophosphoric acid; further, it is admitted by all chemists that orthophosphoric
acid is absolutely inoccuous. I therefore at once incorporate orthophosphoric acid
with the butter, intimately mixing, blending, and incorporating it therewith by
means of a butter-worker, or in any suitable manner.
The solution of orthophosphoric acid which I have found to answer well is, for
every one pound of butter twenty four grains of acid, dissolved in from one half to
one drain of water, which water I prefer should be distilled, but I do not propose
to limit myself to such proportions.
Having now described and ascertained the nature of my said Invention, and in
what manner the same is or may be performed,
I claim as secured to me by the hereinbefore in part recited Letters Patent,-
The preservation of butter by mixing, blending, and incorporating ortho-
phosphoric acid therewith, as hereinbefore specified.
In witness whereof, I, the said George Mander Allender, have hereunto set
my hand and seal, this Fifteenth day of November, in the year of our Lord
One thousand eight hundred and eighty one.
