PROVISIONAL SPECIFICATION.
An Improved Method for Cleaning Chimneys and for Extinguishing
*Fires in the same.

...
I, WILLIAM SAMUEL FROST, trading as Henry Gould & Co., 303, Strand, London,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention consists of a compound composed of sulphur, saltpetre, charcoal
and common salt mixed in suitable proportions, and held in a suitable box
attached to a rivetted holder constructed of metal, ignited and held up a chimney;
or flue, so that the fumes ascend, will clear the chimney or flue of all soot.
Also when held and fired in the same way will immediately extinguish any
chimney on fire.
I claim that by the use of this compound a sweep is never needed as this com-"
pound consumes or destroys the soot adhering to and choking up the flues or
draught passages of a chimney.
