IMPROVEMENTS IN THE MANUFACTURE OF SOAP
Year: 1879

page_text: LETTERS PATENT to Walter Jeyes, of Catherine Street, Aston Cross, Bir-
mingham, Chemist, for the Invention of "IMPROVEMENTS IN THE MANUFACTURE
OF SOAP"
Sealed the 13th April 1880, and dated the 21st November 1879.
PROVISIONAL SPECIFICATION left by the said Walter Jeyes at the Office
of the Commissioners of Patents on the 21st November 1879.
WALTER JEYES, of Catherine Street, Aston Cross, Birmingham, Chemist.'
'IMPROVEMENTS IN THE MANUFACTURE OF SOAP,"
My Invention is designed as an addition to, and an improvement upon, that part
of my Specification filed in fulfilment of the conditions of Her Majesty's Letters
Patent, dated 23 Dec. 1878, No. 5249 (granted to me for my Invention of "An
Improved Compound for Sanitary and Preservative Purposes"), which refers to the
manufacture of soap.
My improvement consists in the employment of anthracine salt, napthaline, or
any similar crystallizable hydro-carbon, whether produced by distillation from coal-
tar, shale, or other mineral, or in any other manner, in combination with the
ordinary ingredients of soap.
One of the said salts is added to and mixed with the ordinary ingredients of
soap at any convenient period during its manufacture before solidification, and in
varying proportion according to the use to which it may be intended to apply the
soap.
By this mode I effect considerable economy over that described in my said
Specification 23 Dec. 1878, No. 5249 while at the same time I give to the soap
an equal degree of sanitary properties as though it had been prepared in the
manner described in my said former Specification.

"IMPROVEMENTS IN THE MANUFACTURE OF SOAP."
My Invention is designed as an addition to, and an improvement upon, that part
of my Specification filed in fulfilment of the conditions of Her Majesty's Letters
Patent dated Twenty third December, One thousand eight hundred and seventy
eight, No. 5249 (granted to me for my Invention of "An Improved Compound for
Sanitary and Preservative Purposes "), which refers to the manufacture of soap.
My improvement consists in the employment of anthracine salt, or napthaline,
whether produced by distillation from coal tar, shale, or other mineral, or in any
other manner, in combination with the ordinary ingredients of soap.
One or more of the said salts is added to and mixed with the ordinary ingredients
of soap at any convenient period during its manufacture before solidification, and
in varying proportion according to the use to which it may be intended to apply
the soap. I find, however, that it is preferable to delay the addition of the salt
until as late a point as may be before solidification, in order to avoid as much as
possible the loss of any of the volatile properties.
By this mode I effect considerable economy over that described in my said
Specification Twenty third December, One thousand eight hundred and seventy
eight, No. 5249, while at the same time I give to the soap an equal degree of
general sanitary detergent and preservative properties as though it had been
prepared in the manner described in my said former Specification.
Having now declared the nature of my Invention and the manner in which it is
to be performed, be it known that the improvements which I consider novel and
desire to protect by Letters Patent are,--
The combination of anthracine salt or napthaline with the ordinary ingredients
of soap, as and for the purposes herein before substantially described.
In witness whereof, I, the said Walter Jeyes, have hereunto set my hand and
seal, this Nineteenth day of May, in the year of our Lord One thousand
eight hundred and eighty.
