page_text: PROVISIONAL SPECIFICATION.
A Washing and Bleaching Compound for Vegetable Fibre or
Textiles.
FRIEDRICH LUDWIG BARTELT, Chemical Manufacturer and Soap Maker,
Keynsham, County of Somerset, do hereby declare the nature of this invention
to be as follows:-
I take a caustic lye preferably caustic soda lye of 24 twaddle strength. To
this I add zinc but preferably zine dust and after the zinc or zinc dust has been
dissolved I allow the whole to settle so that any impurities may be precipitated,
after which I draw off the clear caustic lye with the zine in solution. I do not
bind myself to use only pure zine but I may also use zinc salts such as hydroxide
of zinc and the like. I then add to the drawn off liquor carbonate of soda pre-
ferably about an equal quantity in weight to the liquor stirring it well until it
forms into one even mass. I then allow it to set hard after which I break it
into small nuts and either use it in that form or get it milled and ground. If
it is desired to have a saponifying compound I add with the carbonate of soda a
solution of soap preferably ten per cent. and stir and treat the whole as before
inentioned.
A compound as above described has very high cleansing antiseptic and
bleaching qualities.

A Washing and Bleaching Compound for Vegetable Fibre or
Textiles.
FRIEDRICH LUDWIG BARTELT, Keynsham, Somerset, Chemical Manufacturer
and Soap Maker, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:―
I take a caustic lye preferably caustic soda lye of 24 twaddle strength. I
may however also take a caustic potash lye, or any analogous caustic alkali. To
this add zinc, about 20 per cent. I then dissolve the zinc and allow the whole
to settle so that any impurities may be precipitated, after which I draw off the
clear caustic lye with the zine in solution. I do not bind myself to use only
pure zine but I may also use zinc salts such as hydroxide of zinc and the like.

page_text: I then add to the drawn off liquor about an equal quantity in weight either
carbonate of soda in preference or as the case may be any other detergent alkali or
potash, stirring it well until it forms into one even mass. I then allow it to
set hard after which I break it into small nuts and either use it in that form or
get it milled and ground. If it is desired to have a saponifying compound.
I add soap in solution or any saponifyable oil or fat preferably 10 per cent. and
stir it well so as to form one even mass, when it is ready for use. I do not
confine myself to the exact proportions as before mentioned as the various
qualities of the fibres or textiles to be washed and treated will have to be taken
into consideration in proportionating the ingredients.
A compound as above described has very high antiseptic cleansing and
bleaching qualities.

Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
-
1st. A cleansing bleaching and antiseptic compound, composed of zinc salts
added to carbonate of soda or any other alkaline detergent or saponifying oils,
soap or fat, substantially as described.
2nd. A zinc salt obtained by the employment of a caustic lye preferably
caustic soda lye.
