with a Durable Coating Capable of being Polished.
I, EDWARD ROESE; Manufacturer, of Düsseldorf, Germany, do hereby declare the
nature of my invention for PROCESS AND COMPOUND FOR PROVIDING BILLIARD BALLS
AND OTHER OBJECTS WITH A DURABLE COATING CAPABLE OF BEING POLISHED to be as
follows:-
To provide billiard balls and other articles of ivory, wood, metal or other material
with a durable coating capable of being polished, prepare a compound from an
alcoholic solution of copal varnish and a solution of celluloid, with or without the
addition of colouring matter, and apply this compound to the ball, after having coated.
the latter with an alcoholic solution of copal varnish. The details of the process may
be as follows:
Copal varnish is dissolved in alcohol, and celluloid in sulphuric ether and alcohol;
one part of each solution is added to one part of (6 per cent) collodian, and the desired
quantity of colouring matter, after which the ingredients are thoroughly mixed.
In order to increase the adhesion between this mass and the surface of the billiard
ball, or other article, the latter is coated with a solution of copal-varnish in alcohol,
which forms a connecting link between the surface of the ball (whether made from
ivory or from paper mass) and the compound described above. This compound may
be pressed on to the ball (or other article) by means of moulds, or it may be repeatedly
applied with a brush, until the coating has the desired thickness. Finally the ball
(or other article) may be polished with polishing powder and oil, or in any other suitable
manner.

with a Durable Coating Capable of being Polished.
1, EDWARD ROESE, Manufacturer, of Düsseldorf, Germany, 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 :-
For providing billiard balls with a very durable coating capable of being ground
and polished, prepare a compound from an alcoholic solution of copal varnish, a
solution of celluloid, collodion, and colouring matter, and apply this compound to the
ball, after having coated the latter with an alcoholic solution of copal varnish.
The method of procedure is preferably as follows:
The material for coating surfaces of wood, metal.&c. is obtained by dissolving copal
varnish in alcohol, and celluloid in sulphuric ether and alcohol, adding one part of each
liquid thus prepared to one part of collodion having a strength of 6 per cent, adding
the desired colouring substance and mixing these ingredients thoroughly.
In order to increase the adhesion of this mass to the surface of the billiard ball or
other article, the latter is coated with a solution of copal varnish in alcohol. This
substance combines very intimately with the surface of the ball, as well as with the
coating described above; thus serving as a link between the two.
The coating material may be pressed on to the ball or other article by means of
moulds, or it may be repeatedly applied with a brush until the coat has sufficient
thickness. Finally the article may be polished with polishing powder and oil.
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 :
1. The process for forming on billiard balls and other objects a durable coating.
which consists in covering the said object with an alcoholic solution of copal varnish
and then coating it with a mass composed substantially as described.
2. A compound consisting of an alcoholic solution of copal varnish, a solution of
celluloid in ether and alcohol, and collodion, with or without the addition of colouring
matter, substantially as described and for the purpose specified.
