We JAMES WEST KNIGHTS of 1 Sidney Street Cambridge and WILLIAM DENNISON
GALL of Little Shelford, Cambridgeshire do hereby declare the nature of this
invention to be as follows:-
We take peat, sometimes known as turf dried by exposure to the atmosphere or by
artificial means obtained from bogs or fens and consisting of altered vegetable-tissue
produced by the action of stagnant water or humid atmosphere on plants. The dried
peat may be ground in an edge-runner mill or other suitable grinding apparatus and
sifted. The powder thus produced is mixed by the aid of the same edge-runner mill
or other suitable mixing apparatus with ten fifteen or twenty per cent. or other
suitable quantity of carbolic acid thus producing carbolized peat 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.
If the colour of the ground peat is objectionable red ochre or other pigment may be
ground with it in suitable quantity to give it any desired shade of color.

page_text: We, JAMES WEST KNIGHTS, Chemist of 1 Sydney Street Cambridge and WILLIAM
DENNISON GALL, Tar Distiller of Little Shelford, Cambridgeshire, 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:-
We take peat sometimes known as turf dried by exposure to the atmosphere or by
artificial means, obtained from hogs or fens and consisting of altered vegetable-tissue
produced by the action of stagnant water or humid atmosphere on plants. The dried
peat 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 sievo, of the required size say a mesh of 16 io
12 per inch. The powder thus produced is mixed by the aid of the same edge-runner
mill or other suitable mixing apparatus, with ten fifteen or twenty per cent. or other
suitable quantity of carbolic acid until the carbolic is ontirely absorbed the product
being a practically dry powder thus producing carbolized peat 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 say for example
sanitas or creosote.
If the colour of the ground peat is objectionable rod ochre or other pigment may
he ground with it in suitable quantity to give it any desired shade of colour.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is :-
1. The use of peat as a base or vehicle in disinfecting or antiseptic powders.
2. In the manufacture of disinfecting or antiseptic powders the combination with
peat of an antiseptic such as carbolic acid sanitas creosote or the like substantially as
specified.
8. The manufacture of disinfecting or antiseptic powder substantially as specified.
