PROVISIONAL SPECIFICATION.
Improvements in Compositions or Powders for Cleaning, Polishing,
Purifying, and Disinfecting Knives, Plate, and other Culinary or
Table Utensils.
JOHN JOHNSON of St. Annes Works Liverpool in the County of Lancaster Black
Lead Manufacturer, do hereby declare the nature of this invention to be as follows:-
It is believed that a considerable amount of preventible disease and blood poisoning
has been caused at one time or another by the use of infected knives and forks,
spoons, plate etcetera at restaurants and other places. It is for the purpose of
preventing chances of such infection that this invention is designed.
In place of using ordinary polishing or cleaning powders I use a mixture of any
desired polishing or cleaning powder or paste with a disinfectant.
For instance,
rouge and sanitas powder mixed up together, or I may add to the polishing powders
at present used an oxidizing agent such as permanganate of potash. The disinfectant
and the cleaning or polishing paste are well ground up or mixed together and sold
in the nixed form.
