page_text: I, CHARLES HENRY COIFFIER, of 52 Gracechurch Street, in the City of London,
Ivory Turner, do hereby declare the nature of this Invention to be as follows:-
My Invention relates to a new Composition, more especially intended for making
Billiard Balls, but which may also be employed, with equal advantage, for the
manufacture of other articles suitable for being moulded, turned, or carved, such
as those usually made by Ivory Turners. Billiard Balls made of this new composi-
tion possess all the qualities of Ivory balls; vizt elasticity, polish, hardness, and
resistance to wear.
My Invention consists, essentially in mixing horn-dust, with a coloring-matter,
and a suitable agglomerant. For white products, it is preferred to employ zinc
white, as the coloring matter; for red products, French, or English vermilion; for
blue products, cobalt, ultramarine blue, etc.
The horn-dust is mixed with the coloring matter, either dry, or in a moist condi-
tion, with the addition, if necessary, of some agglomerating substance. I prefer
to employ albumen (white of egg) as the agglomerant, in all cases where judged
suitable, in order to give body to the coloring matter, and thus become intimately
mixed with the composition. When the composition is brought to the desired
consistency, it is moulded; after which it may be turned. The moulding may be
effected while the composition is in a heated condition, either by hand, or by
mechanical means. It should be understood, that I do not limit myself to any
particular mode of manipulating, or using this composition, which will vary,
according to the purpose to which the same is to be applied; besides that of
making billiard-balls.
By means of my Invention, I am thus enabled to produce billiard-balls, possessing
all the qualities of Ivory balls, from a material which is both more economical, and
more easily procurable.

I CHARLES HENRY COIFFIER of 52 Gracechurch Street, in the City of London
Ivory Turner do hereby declare the nature of my invention for ".A COMPOSITION
FOR THE MANUFACTURE OF BILLIARD BALLS, AND OTHER ARTICLES and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
My invention relates to a new composition more especially intended for making
billiard balls, but which may also be employed with equal advantage for the
manufacture of other articles suitable for being moulded, turned, or carved, such
as those usually made by Ivory-Turners. Billiard balls made of this new composi-
tion possess all the qualities of Ivory balls, viz:—elasticity, polish, hardness, and
resistance to wear.
My invention consists essentially in mixing horn-dust with a coloring matter
and a suitable agglomerant. For white products it is preferred to employ zinc
white as the coloring matter, for red products, French or English vermillion; for
blue products, cobalt, ultramarine blue etc. The horn-dust is mixed with the
coloring matter either dry or in a moist condition, with the addition if necessary
of some agglomerating substance.
I prefer to employ albumen (white of egg) as the agglomerant in all cases where
judged suitable, in order to give body to the coloring matter, and thus become
intimately mixed with the composition. When the composition is brought to the
desired consistency it is moulded, after which it may be turned. The moulding
may be effected while the composition is in a heated condition, either by hand or
by mechanical means. It should be understood that I do not limit myself to any
particular mode of manipulating or using this composition, which will vary
according to the purpose to which the same is to be applied besides that of
making billiard balls.
By means of my invention I am thus enabled to produce billiard balls possessing
all the qualities of Ivory balls from a material which is both more economical and
more easily procurable.
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 :-
The herein described composition for the manufacture of billiard balls and other
articles in imitation of ivory, consisting of a mixture of horn-dust and a coloring
matter with or without a suitable agglomerating substance preferably egg albumen,
substantially as specified.
