Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both
in the County of Lancaster, 118, New Street, Birmingham, in the County of
Warwick, and 322, High Holborn, in the County of Middlesex, Civil Engineer,
do hereby declare the nature of this invention to be as follows:-
This invention has for its object the manufacture of a water-resisting and
impermeable paste-gum or coating which is obtained by means of celluloid
dissolved or simply softened by one or more suitable solvents such as acetone.
acetic acid, ether, alcohol. or the like pure or mixed, and in this case with the
addition of other suitable substances dissolved or otherwise such as resins, oils,
gums, waxes or the like, vegetable refuse or even tale, chloride of magnesium,
mineral or organic salts, vegetable, mineral or animal powders, etcetera.
This paste is intended either for sticking articles together, such as wood,
cardboard, cord, fabrics, cork, leather or the like, or for covering them over the
whole or part of their surface with an impermeable layer which protects them
entirely from contact with and from the action of water whether fresh water,
salt water, household water or the like.
Dissolved or softened celluloid which is a plastic material obtained by means
of gun cotton and camphor, whatever may be its name, its preparation, its mode
of fabrication, its condition, or its composition, forms the basis and constitutes
the integral and essential element. It is previously dissolved or sufficiently
softened as herein before stated in order that one or more of the substances herein-
before mentioned may be added. The addition of these is intended to impart to
the mixture the qualities of adherence, solidity, inflammability, flexibility
or other qualities according to the use to which it is to be put.
This mixture is usually made whilst cold by simple agitation.
This improved paste-gum or coating to which the inventors have given the
name of Calfatine" is usually of a brown colour, but it may be made white or
of other suitable colours as desired such as blond or wood colour etcetera. It
may even be transparent and colourless.
Calfatine" may be employed not only for use on objects at the moment of
their manufacture but also for repairing articles broken, or deteriorated by water,
such as old furniture, vehicles, wagon covers and the like.
It may be treated with essences or perfumes, rendered antiseptic and also anti-
septicized by means of antiseptic substances, such as phenic acid, thymol sublimate.
or any other suitable antiseptic substance.
It is applied whilst cold by means of a knife, spatula, the hand or in any other
manner.

I, WILLIAM l'HILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both
in the County of Lancaster, 118, New Street, Birmingham, in the County of
Warwick, and 322, High Holboru, in the County of Middlesex, Civil Engineer,
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 its object the manufacture of a water-resisting and
impermeable paste-gum or coating which is obtained by means of celluloid
dissolved or simply softened by one or more suitable solvents such as acetone,
acetic acid, ether, alcohol or the like pure or mixed, and in this case with the
addition of other suitable substances dissolved or otherwise such as resins, oils,
gums, waxes or the like, vegetable refuse or even talc, chloride of magnesium,
mineral or organic salts, vegetable, mineral or animal powders, etcetera.
This paste is intended either for sticking articles together, such as wood,
cardboard, cord, fabrics, cork, leather or the like, or for covering them over the
whole or part of their surface with an impermeable layer which protects them
entirely from contact with and from the action of water whether fresh water,
salt water, household water or the like.
Dissolved or softened celluloid which is a plastic material obtained by means
of gun cotton and camphor, whatever may be its name, its preparation, its mode
of fabrication, its condition, or its composition, forms the basis and constitutes
the integral and essential element. It is previously dissolved or sufficiently
softened as herein before stated in order that one or more of the substances herein-
before mentioned may be added. The addition of these is intended to impart to
the mixture the qualities of adherence, solidity, non-inflammability, flexibility
or other qualities according to the use to which it is to be put.
This mixture is usually made whilst cold by simple agitation.
This improved paste-gum or coating to which the inventors have given the
name of Calfatine" is usually of a brown colour, but it may be made white or

Calfatine" may be employed not only for use on objects at the moment of
their manufacture but also for repairing articles broken, or deteriorated by water.
such as old furniture, vehicles, wagon covers and the like.
It may be treated with essences or perfumes, rendered antiseptic and also anti-
septicised by means of antiseptic substances, such as phenic acid, thymol sublimate
or any other suitable antiseptic substance.

The proportions of the products entering into the composition of "Calfatine"
will vary according to the special applications to which it is to be put; the fol-
lowing proportions have however been found to give good results, and are here
given as an example:-

Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondents, I declare that what I claim is:-
An impermeable, water resisting, non-inflammable paste-gum or coating
obtained by dissolving celluloid in acetone, acetic acid, ether, alcohol or the like
substantially as hereinbefore described.
