Year: 1849

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I,. EWALD
RIEPE, of Finsbury Square, in the County of Middlesex, Merchant, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Thirtieth day of
January, One thousand eight hundred and forty-nine, in the twelfth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Ewald Riepe, my exors, adiñors, and assigns, Her especial.
licence, full power, sole privilege and authority, that I, the said Ewald
Riepe, my exors, admñňors, and assigns, or such others as I, the said Ewald
Riepe, my exors, adiñors, or assigns, should at any time agree with, and
no others, from time to time and at all times during the term of years.
therein expressed, should and lawfully might make, use, exercise, and vend,
within England, Wales, and the Town of Berwick-upon-Tweed, the Invention
of "IMPROVEMENTS IN THE MANUFACTURE OF SOAP," partly communicated by
Anton Lohage, a foreigner residing abroad, and partly invented by. myself;
in which said Letters Patent is contained a proviso that I, the said Ewald
Riepe, shall cause a particular description of the nature of the said

page_text: Invention, and in what manner the same is to be performed, by an in-
strument in writing under my hand and seal, to be inrolled in Her said
Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said in part recited Letters Patent, as in
and by the same, reference being thereunto had, will more fully and at
large appear.
NOW KNOW YE, that, in compliance with the said proviso, I, the
said Ewald Riepe, do hereby declare that the nature of the said Inven-
tion, and the manner in which the same is to be performed, are fully
described and ascertained in and by the following statement thereof (that is
to say):
The Invention consists of a mode of applying carbonated alkali in the
manufacture of soap. And in order that the Invention may be most fully
understood and readily carried into effect, I will proceed to describe the means
pursued by me.
I proceed to make a saponaceous glue in the ordinary manner by means
of caustic alkaline lye, using such lye as pure as conveniently can be
obtained, and then I complete the saponification by using a stronger
lye, and to this saponaceous compound I add of a pure or nearly pure
carbonated alkali such a quantity that the real alkali therein shall be
about one half of the real alkali in the said saponaceous compound; but
this proportion between the caustic and carbonated alkali may be varied,
and I prefer to employ the carbonated alkali in the dry or calcined
state; and I introduce it into the saponaceous compound when that
compound is in such a state of concentration that a sample of it taken
up on a trowel or pallet knife shall flow off therefrom in clotted lumps.
The carbonated alkali will be quickly dissolved in the saponaceous com-
pound as it boils up, and when it is dissolved, the process is complete,
and the soap is then to be cleansed or completed in the ordinary manner.
Having thus described the nature of the Invention, and the manner in
which the same is to be performed, I would state that I do not confine
myself to the details as herein described; but what I claim is, the
combination of carbonated alkali, as above set forth, in the manufacture
of soap.
In witness whereof, I, the said Ewald Riepe, have hereunto set my hand
and scal, this Twenty-eighth day of July, in the year of our Lord One
thousand eight hundred and forty-nine.
EWALD (L.S.) RIEPE.
