Improved Means for Preventing the Accumulation of Soot in Flues
and Shafts.
We, THOMAS BRIGGS, of Stapleford, in the County of Cambridge, Gentleman,
and JOHN CRAMPTON, Chemist, and FRANK EDWARDS, Surgeon, both of Sawston, in
the said County of Cambridge, do hereby declare the nature of this invention to be
as follows:-
Our invention consists of a powder composed of flour of sulphur, chloride of
sodium, potassium nitrate, cupreous sulphate, muriate of ammonia, and red ochre,
or any other suitable colouring matter, mingled in about the following proportions,
(that is to say)
Flour of sulphar
Chloride of sodium
Potassium nitrate
Cupreous sulphate

Muriate of ammonia
Red ochre or its equivalent, in any suitable proportions to produce the desired
tint. Such of these ingredients as are not already in the form of a powder are
pulverized or finely ground previous to mixing, to facilitate their blending with the
other constituents and so producing a mechanical mixture. A little of this mixture
placed on a fire clears the latter, while the gases evolved by combustion act upon
the soot and destroy the same.
By our invention we dispense with brushes and other mechanical appliances for
the removal of soot, and thereby not only effect a considerable economy in time and
labour but likewise avoid the inconvenience caused by removing soot in the ordinary
manner.

By our invention we dispense with brushes and other mechanical appliances for

labour, but likewise avoid the inconvenience caused by removing soot in the ordinary
manner.
We would here observe that the quantities of the various ingredients herein-
before specified may be varied, provided that the quantities used bear a similar
ratio to each other as those herein before mentioned, as for instance, flour of
sulphur 1 lb, chloride of sodium 7 lbs, potassium nitrate 4 lbs,-cupreous
sulphate 7lbs, muriate of ammonia 8 lbs.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
As a new and useful article of manufacture for use for the prevention of the
accumulation of soot in flues and shafts a composite powder consisting of flower of
sulphur, chloride of sodium,-potassium nitrate,-cupreous sulphate,-muriate of
ammonia, and red ochre, or its equivalent, combined substantially in the proportions
and manner herein before specified.
