A. COMBINED DISINFECTING AND FUMIGATING COMPOUND
Year: 1885

page_text: We THOMAS STONER of 22 Neal Street Bradford in the County of York, Slate
Merchant; and JOHN TURTON of 44 Thomas Fold Shipley in the aforesaid County
Manufacturing Chemist do hereby declare the nature of our said invention for
A. COMBINED DISINFECTING AND FUMIGATING COMPOUND to be as follows:-
This invention relates to a new disinfecting and fumigating compound, which is
perfectly soluble in water and may be advantageously used for all disinfecting
purposes, and is also equally effective when used for fumigating.
To carry out our invention, we mix the following ingredients the proportions of
which may be somewhat varied; twelve parts common salt crushed to a fine
powder, two parts light tar oil of seven percent specific gravity, one part crude
carbolic acid of ten percent specific gravity, to which is added a fraction of a part
of oil of cucalyptus, the ingredients are thoroughly mixed together until they
become a light yellow colour. A gradual chemical action then takes place,
materially increasing the percentage of carbolic acid.
For some purposes we may add to the above compound a small percentage of
powdered wormwood.

for A COMBINED DISINFECTING AND FUMIGATING COMPOUND and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
This invention relates to a new disinfecting and fumigating compound, which is
soluble in water and may be advantageously used for all disinfecting purposes, it is
also equally effective when used for fumigating.
To carry out our invention we mix the following ingredients, Twelve parts
common salt crushed to a fine powder. Two parts light tar oil of seven per cent
specific gravity. One part crude carbolic acid of ten per cent specific gravity to
which is added one fourth of a part of oil of eucalyptus. These ingredients are
thoroughly mixed together until they become a light yellow colour. A gradual
chemical action then takes place in the compound, materially increasing the
percentage of carbolic acid, the maximum percentage being reached when the
compound as attained a dark grey colour. When it is not essential that the
compound should be entirely soluble in water we add to the above mentioned
ingredients one fourth of a part of powdered wormwood.
We would have it understood that the proportions.indicated in the above receipt,
are not absolute but they may be slightly altered without departing from the
nature of the invention and they are only mentioned as those we consider to be
the best.
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
The combination of the hereinbefore mentioned ingredients forming the combined
disinfecting and fumigating compound substantially as described.
