Complete Specification Left, 13th Apr., 1889
Complete Specification Accepted, 25th May, 1889
I, EDWARD OATES, of 44, Rue d'Enghien, Paris, in the French Republic, do hereby
declare the nature of this invention to be as follows:-
1
This Invention relates to an improved composition of matter, by means of which
oil and certain other paints may be rapidly and efficiently removed from wood, metal
and other surfaces.
In the execution of my Invention, I proceed by preference as follows:
Into a closed boiler of suitable material and capacity, 1 introduce 50 pounds of
caustic soda lye at 40° Baumé (= Sp. Gr. 1.3570) and 8 pounds of Iceland moss-
and after thorough stirring, the liquid is gently heated up to ebullition, at which
point it is maintained for about an hour, when it is left to cool.
When completely cold, I add thereto 100 pounds weight of caustic potash at about
83 per cent., then boil again, and after solution of the potash allow it to cool down as
before, when I incorporate a quantity of potatoe starch in the proportion of from
6 to 8 per cent. of the mass, which then constitutes the improved paint remover.

page_text: I, EDWARD OATES, of 44, Rue d'Enghien, Paris, in the French Republic, 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 relates to an improved composition of matter, by means of which
oil and certain other paints may be rapidly and efficiently removed from wood, metal
and other surfaces.
In the execution of my Invention, I proceed by preference as follows:
Into a closed boiler of suitable material and capacity, I introduce 50 pounds of
caustic soda lye at 40° Baumé (= Sp. Gr. 1,3570) and 8 pounds of Iceland moss-
and after thorough stirring, the liquid is gently heated up to ebullition, at which

When completely cold, I add thereto 100 pounds weight of caustic potash at about
per cent. then boil again, and after solution of the potash allow it to cool down
as before, when I incorporate a quantity of potato starch in the proportion of from
6 to 8 per cent. of the mass, which then constitutes the improved paint remover.
The compound prepared as above is applied by brush or otherwise to the paint
which it dissolves off with perfect regularity, whatever may be the number or age of
the coats, without attacking the wood or metal surfaces beneath, and without the
tendency to running inherent to all paint removers at present known.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what I
claim is:
An improved Composition of matter for removal of oil and certain other paints
from wood and other surfaces, obtained by boiling Iceland inoss in a Solution of
Caustic Soda, adding Caustic potash to the cooled product of this operation,-reboiling
the whole, and after final cooling, incorporating potato Starch therewith, substantially
as and for the purpose herein set forth.
