PROVISIONAL SPECIFICATION.
Improved Manufacture of Disinfecting Powder.
I, THOMAS HOWELL WILLIAMS Ockbrook near Derby, Secretary of a Public
Company do hereby declare the nature of this invention to be as follows:-
I take barley after being used for brewing purposes called grains, dried by
exposure to the atmosphere or by artificial means.
The dried barley or grains may be ground in a edge runner mill or other suitable
grinding apparatus and sifted. The powder produced is mixed by the aid of the
same edge runner mill or suitable mixing apparatus with 10, 15 or 20 per cent. of
carbolic acid, thus producing carbolised grains or disinfecting powder which may
be used for all purposes that an ordinary disinfecting powder is used for.
Other antiseptic substances can be used instead of carbolic acid such as, creosote,
sanitas.
If the color of the ground grains is objectionable, red ochre or other suitable
pigment may be ground with it in suitable quantities to give it desired shade
or tint.

COMPLETE SPECIFICATION.
Improved Manufacture of Disinfecting Powder.
I THOMAS HOWELL WILLIAMS of Ockbrook near Derby Secretary of a Public
Company 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 barley which has been used for brewing purposes sometimes called
"grains" dried by exposure to the atmosphere or by artificial means. The dried
grains may be ground in an edge runner mill or other suitable grinding apparatus
and sifted to secure an even size.
The grinding is done in a dry state and continued until the material will pass
through the sieve of the required size say a mesh of 16 to 12 per inch. The dry
powder thus produced is mixed by the aid of the same edge runner mill or other
suitable apparatus with ten fifteen or twenty per cent. or other suitable quantity of
carbolic acid until the carbolic acid is entirely absorbed the product being a
practically dry powder. Thus producing carbolised grains or disinfecting powder
which may be used for all purposes that an ordinary disinfecting powder may be
used for. I do not confine myself to the use of carbolic acid-other disinfecting
and antiseptic substances such as sanitas, creosote, eucalyptus can be used instead
of or together with carbolic acid.
If the colour of the ground grains is objectionable red ochre or other pigment
may be ground or mixed with the powder in suitable quantities to give any desired
shade or colour.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is performed I declare that what I
claim is :-
1. The use of grains as a base or vehicle for disinfecting or antiseptic powders.

page_text: with grains of disinfecting or antiseptic substances such as carbolic acid, sanitas,
creosote, eucalyptus, or the like substantially as specified.
3. The manufacture of disinfecting or antiseptic powder substantially as
specified.
Dated this 2nd day of March 1892.
