Year: 1872

page_text: LETTERS PATENT to Vincenz Van Baerle, of Worms, in the Empire
of Germany, now residing at Seyd's Hotel, No. 39, Finsbury
Square, in the City of London, for the Invention of "IMPROVEMENTS
PROVISIONAL SPECIFICATION left by the said Vincenz Van Baerle
at the Office of the Commissioners of Patents, with his Petition,
on the 19th June 1872.
I, VINCENZ VAN BAERLE, of Worms, in the Empire of Germany, now
residing at Seyd's Hotel, No. 39, Finsbury Square, in the City of
London, do hereby declare the nature of the said Invention for "Iм-
PROVEMENTS IN THE MANUFACTURE OF SOAP OR COMPOSITIONS FOR WASHING
PURPOSES," to be as follows:-
In the manufacture of soap or composition for washing purposes,
according to this Invention, concentrated silicate of soda or potash when
heated is neutralized with fat or oil, and to this is added a quantity of

page_text: glycerine, say from 5 to 20% or more, and the composition is kept
agitated until it is nearly cold. The object of putting glycerine into the
composition is to maintain it in a moist state and to prevent its acting
injuriously upon delicate colors or textures, but especially for linen and
white fabrics the addition of glycerine is not essential and only serves
to keep the composition in a state to be more quickly and readily used.
The silicate composition may however be prepared either with or
without the glycerine.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Vincenz Van Baerle in the Great Seal Patent Office
on the 18th December 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, VINCENZ
VAN BAERLE, of Worms, in the Empire of Germany, now residing at
Seyd's Hotel, No. 39, Finsbury Square, in the City of London, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of June, in the year of 2
our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Vincenz Van Baerle, Her special license
that I, the said Vincenz Van Baerle, my executors, administrators, and
assigns, or such others as I, the said Vincenz Van Baerle, my executors,
administrators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN THE
MANUFACTURE OF SOAP OR COMPOSITIONS FOR WASHING PURPOSES," upon the
condition (amongst others) that I, the said Vincenz Van Baerle, my
executors or administrators, by an instrument in writing under my, or
their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same

page_text: was to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said Vincenz Van Baerle, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say:—
In the manufacture of soap or composition for washing purposes,
according to this Invention, concentrated silicate of soda or potash when
heated is added to grease or oil which has been saponified to a slight
degree, and to this is added a quantity of glycerine say about 5 per cent.,
and the composition is kept agitated until it is nearly cold. The object
of putting glycerine into the composition is to maintain it in a moist
state and to prevent its acting injuriously upon delicate colors or
textures, but especially for linen and white fabrics the addition of
glycerine is not essential and only serves to keep the composition in a
state to be more quickly and readily used. The silicate composition may
however be prepared either with or without the glycerine.
A soap or composition made as above described may either be used by
itself for washing purposes or it may be added to soap made in the
ordinary manner.
In practically carrying out my Invention I first saponify grease or
oil to a slight degree in the ordinary manner of soap making, and after
the soap has been boiled for some hours I add to it about 10 to 15 times
its weight of concentrated and slightly alkaline silicate of soda or potash
which has been previously heated, the proportion of silicate of soda or
potash used may however be considerably varied. The silicate of soda or
potash is added little by.little to the saponified grease or oil which is
kept agitated until the whole of the silicate of soda or potash has been
added and until the mixture is nearly cold. A small per-centage of
glycerine, say about 3 or 5 per cent., is also added The proportion of
glycerine used is varied according to the temperature, more will be
required in summer and less in winter.
A washing composition made as herein-before described is not only
applicable generally for washing purposes, but may also be used very
advantageously in place of soda ash for boiling with yarns and fibres

page_text: previous to their being passed through the ordinary bleaching process,
and similarly for preparing cloth for bleaching. By thus boiling the
cloth or yarns with the washing composition in place of as heretofore
with a solution from soda ash to prepare them for the bleaching process,
the chlorine bath to which they are afterwards subjected need only be of
about one half the strength now ordinarily used. The washing com-
position may also be used for boiling with rags, esparto, and other
vegetable fibres for paper making in place of boiling them with a
solution obtained from soda ash as now usual, and also for boiling with
fibrous substances previous to their being submitted to dyeing operations.
Having thus described my Invention, and the manner in which I
carry it into effect, I would have it understood that I claim the manu-
facture of a washing composition substantially as herein described.
In witness whereof, I, the said Vincenz Van Baerle, have hereunto
set my hand and seal, this Fifteenth day of December, in the
year of our Lord One thousand eight hundred and seventy-
two.
