PROVISIONAL SPECIFICATION.
Improved Compounds for Preventing, Subduing, or Extinguishing
Fire.
I, SAMUEL WAYMOUTH, of 117, Seven Sisters Road, County of London,
School Master, do hereby declare the nature of this invention to be as follows:
This invention has for object, the compounding or preparation of ingrédients or
substances for admixture with water 'to be employed for subduing, or extinguishing
fire, the compound being also applicable as a coating to an inflammable body
material to prevent fire.
:
For the purpose of my invention, I take ordinary clay and whiting in about
equal proportions and by agitation dissolve them in water: "I add glue, size, .or
other adhesive to make a sticky substance. I then evaporate the water from the
compound and grind, or otherwise reduce it to small particles, or to fine powder to
beafterwards mixed with water for use as a fire extinguisher.
The powder can be mixed with oil paints and employed in combination as 'a
coating for all kinds of surfaces, such as wood, canvas, and the like to prevent
fire.
I have referred to clay and whiting but other earthy substances may be used
therewith, or in substitution for them and having the properties which ordinary clay
and whiting possess for the purpose...
L
The action of the compound upon à fire is to form a crust as the water is
destroyed by heat and so prevent the entrance of oxygen thereto.

Improved Compounds for Preventing, Subduing, or Extinguishing
Fire.
I, SAMUEL WAYMOUTH, of 117, Seven Sisters Road, County of London,
School Master, do hereby declare the nature of this invention, and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
This invention has for object, the compounding or preparation of ingredients or
substances for admixture with water to be employed for subduing or extinguishing
fire, the compound being also applicable as a coating to an inflammable body or
material to prevent fire.
For the purpose of my invention, I take ordinary clay and whiting or chalk in
about equal proportions and by agitation dissolve them in water. 1 add glue, size,
or other adhesive to make a sticky substance. I then evaporate the water from
the compound and grind, or otherwise reduce it to small particles, or to fine powder
to be afterwards mixed with water for use as a fire extinguisher.
The powder can be mixed with oil paints and employed in combination as
a coating for all kind of surfaces, such as wood, canvas, and the like to prevent
fire.
I have referred to clay and whiting but other earthy substances may be used
therewith, or in substitution for them and having the properties which ordinary clay
and whiting possess for the purpose.
The action of the compound upon a fire is to form a crust as the water is

page_text: destroyed or becomes evaporated by heat and so prevent the entrance of air
thereto.
In buildings, the timbers for joists, the laths, panelling, and other parts used as
permanent portions of the structure are preferably first smeared with or dipped
into the fire subduing liquid, so that the pores are more or less impregnated and the
surface coated previous to being placed or nailed in position.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what 1
claim is :-
1. The preparation and use of a compound for coating, surfacing, and in some
cases impregnating, inflammable material, to check or prevent combustion in cases
of fire said compound being composed of earthy substances and an adhesive
admixed with water for ready application by hand from buckets, or by power from
pumps, as set forth.
2. The application of semi-liquid compound (earthy matters and water) by
splashing, spraying, or spreading it upon burning property to reduce, or to prevent
extension of fire, as described.
:.. 3. Impregnating, saturating, coating, or surfacing inflammable material with a
compound in semi-liquid state (earth, water, size) as a preventative of fire as set
forth.
