We, RICHARD JOSEPH STEPHENS of 34 Belvoir Street, Leicester, Architect
and Surveyor and JOHN HEWES of East Street, London Road, Leicester,
Builders' Agent, do hereby declare the nature of this invention to be as follows:-
This invention is designed mainly with the object of providing a disinfectant or
deodorant which is specially applicable for use in public urinals and conveniences
for cleansing and purifying same, although it can be used for other disinfecting and
deodorising purposes.
The disinfectant or deodorant constituting the present invention is particularly
useful for preventing (and for removing when formed) the "incrustation" or
slimy-coating which forms or collects on the sides of public urinals and which
gives rise to a noxious smell.

According to this invention the disinfectant or deodorant consists of a combina-
tion of ground or powdered "Crich" lime and powdered charcoal in suitable
proportions.
These ingredients may also have combined with them camphor and alum either
separately or together in any suitable quantities or proportions.
The said invention therefore consists of either the first two named ingredients
or of a combination therewith of one or both of the latter named materials.
