LYE COMPOSITION
OTHER
This invention relates to the manufacture of solid lyes of the kind described in
the Specification of a Patent granted to Arthur Charles Henderson bearing date
the 11th day of May AD. 1878. and numbered 1899 and consists partly in
modifications of the materials employed and in the proportions thereof, and partly
in an improved process or mode of converting the said materials into the manu-
factured solid lye. For the purposes of the present invention the following
ingredients and process are employed.
Into a boiler or copper is placed say 800 litres of water, 7 kilogrammes of
facus crispus (lichen) and 10 kilogrammes of liquid caustic soda at 40° Beaumé.
This mixture is boiled until a perfect emulsion is obtained which is passed while
hot through a strainer or sieve.
Into a receiver of a capacity of about 1200 to 1500 litres, furnished with a tap
are placed
500 litres of the preceding preparation in either a hot or cold state.
500 kilogrammes of silicate of soda or silicate of potass.
500 kilogrammes of liquid soda called caustic soda.

page_text: Into a large shect iron back is placed from 30 to 50 kilogrammes of oleic acid
(oleine) or of palm oil, cocoa oil, or other fatty body, suitable for saponification
which is triturated with about 40 kilogrammes of carbonate of soda.
After this preparation the liquid is drawn off from the receiver and is poured
into the back. 1000 kilogrammes of carbonate of soda is incorporated little by
little with the contents of the back by mixing with shovels or otherwise, until
complete homegeniety is attained.
In this state the product is removed from the back by means of shovels or other
convenient means and thrown into moulds of, for example, trapezoidal section with
inclined ends, where it is moulded and quickly hardens.
When removed from the moulds the solid lye may be delivered direct for use or
it may be cut or broken into regular or irregular pieces by a mechanical or manual
process.
The employment of this solid lye assures by the detersive quality of the same
a considerable economy of soap as compared with the consumption usually required
for bleaching linen; it completely obviates the necessity for Javel water so
injurious to fine and other linen, and thus effects not only a commercial but also,
and especially, a domestic economy as it does not stain or burn the linen like the
caustic salts of soda or potash usually employed.
This product is emminently suited for washing linen, bleaching stuffs or tissues
and for other purposes, it is not a soap as it serves exclusively for making a lye,
consequently it must not be confounded with the various compositions of soap
heretofore known or used.
The proportions of the materials above indicated are suitable for washing clothes
and household linen, they may be varied somewhat when the lye is intended
to be used for washing new fabrics, wollen materials, rags, printing type and so
forth.

page_text: The proportions of the materials above indicated are suitable for washing clothes
nd household linen, they may be varied somewhat when the lye is intended to be
sed for washing new fabrics, woollen materials, rags, printing type and so forth,
ccording to circumstances.
It may be here mentioned that one litre is equal to about 22 of a gallon, and
at one Kilogramme is equal to about 2.2 lbs avoirdupois.
It is obvious that the actual quantities used in the operation of manufacture
ay be varied so long as the relative proportions are substantially maintained the
antities named being merely given as an example.
Having now described the nature of the said invention and the manner in
hich the same is to be carried into effect I would have it understood that
hat I claim as the invention to be secured by the within in part recited letters
atent is
irst The manufacture of solid lye composition for washing and bleaching linen
and for other purposes by combining together carbonate of soda, silicate
of soda, or silicate of potass, colophony or resin, liquid fucus with a soda
base, and oleic acid or oleine, substantially in the proportions herein-
before specified.
econd The process of manufacturing the solid lye as herein before described such
process consisting substantially as follows:-
Firstly, in mixing together as described 800 litres of water, 7 Kilo-
grammes of Fucus crispus, 10 Kilogrammes of colophony or resin, and
12 Kilogrammes of caustic soda at 40° Beaumé, producing what may be
called mixture No. 1.
Secondly, in mixing together 500 Kilogrammes of the mixture No. 1,
500 Kilogrammes of silicate of soda or silicate of potass, and 500
Kilogrammes of caustic soda, producing what may be called mixturo
No. 2.
Thirdly, in adding to the mixture No. 2, 30 to 35 Kilogrammes of
oleic acid or oleine triturated with about 40 Kilogrammes of carbonate of
soda, producing what may be called mixture No. 3 and
Fourthly, in adding gradually to the mixture No. 3 1000 Kilogrammes
of carbonate of soda.
In witness whereof I the said William Henry Beck have hereunto set my
and and seal this Eighteenth day of August in the year of our Lord One
housand eight hundred and eighty two.
