PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Material applicable for Golf
Balls and other Articles.
We, ALEXANDRE DE PONT and SILVIUS DE PONT, of The Synthetic Ivory
Company, Lune Mills, Lancaster, in the County of. Lancaster, Manufacturers, do
hereby declare the nature of this invention to be as follows:-
The invention relates to a new compound specially suitable for the manufacture
of golf balls.
At the present time golf balls are almost exclusively made of rubber or gutta
percha the principal object of our invention is to produce a ball much cheaper while
possessing all the necessary qualities of the substances now in use.
It consists essentially of a new compound or material composed of cellulose wood
pulp cork dust or fibre with suitable agglutinants such as gums albumen or the like
and a small percentage of rubber or gutta percha intimately mixed together and
compressed together under heat at a very high pressure.
In carrying out the invention we take cellulose wood pulp cotton waste vegetable
fibre or cork dust which we combine with gums albumen or other suitable
agglutinants in due proportion either in a dry state or treated with solvents such as
methyl benzine turpentine bisulphide of carbon or other well known solvents to
which we add a small percentage of rubber or gutta percha when we want to
increase the elasticity of the article to be made out of such compound. The whole
admixture is well blended in a levigating and mixing machine and is afterwards
left for some time to dry and harden when it is ground fine and subjected to heat
and compressed together under a very great pressure.
In addition to golf and other balls the material may be used for a variety of
purposes such as panels ceiling rosettes finger plates etcetera.

Improvements in the Manufacture of Material applicable for Golf
Balls and other Articles.
We, ALEXANDRE DE PONT, and SILVIUS DE PONT, of The Synthetic Ivory
Company, Lune Mills, Lancaster, in the County of Lancaster, Manufacturers, 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 :-
The invention relates to a new compound specially suitable for the manufacture

page_text: It consists essentially of a new compound or material composed of cellulose wood
pulp cork dust or fibre albumen and certain gums such as copal or mastic or other
agglutinants (with or without a small percentage of rubber or gutta percha)
intimately mixed together and compressed under heat at a very high pressure.
In carrying out the invention we at present prefer to employ cellulose or wood
pulp as the basis of the composition and this material in a thoroughly dry state we
mix with albumen in sufficient proportion so that the pulp will be thoroughly
impregnated therewith. Egg albumen we find to be the best for the purpose.
To this mixture we then add in a liquid state copal, mastic or other gum or
agglutinant.
To the solution of copal or mastic gum may be added a small quantity of gutta
percha or rubber in solution when it is desired to increase the elasticity of the
resulting article or gutta percha or rubber in solution may be added separately or
instead of a portion of the gum solution.
Although we prefer to employ material in the form of pulp we may use cotton
waste or other vegetable fibre or cork dust as a base and treat these in a similar
way with albumen and agglutinating gums.
We find that we get very good results from the materials named when mixed in
about the following proportions which we give as an example though it is to be
understood that these proportions may be varied according to the density or
elasticity required in the product.
Cellulose or wood pulp
Albumen
Solution copal mastic or other gums
Solution gutta percha or rubber
60 per cent.
15 per cent.
15 per cent.

10 per cent.
The whole admixture is well blended in a levigating and mixing machine and
is afterwards left for some time to dry and harden when it is ground fine and
subjected to heat and compressed together under a very great pressure.

In addition to golf and other balls the material may be used for a variety of
purposes such as panels ceiling rosettes finger plates etcetera.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1
1. A compound material composed of cellulose, wood pulp, cork dust, cotton
waste or other vegetable fibre albumen and suitable agglutinating gums (with
or without rubber or gutta percha) intimately mixed together and compressed
under a very great pressure substantially as described.
2. A golf or other ball composed of cellulose, wood pulp, cotton waste or other
vegetable fibre or cork dust mixed with albumen and gum mastic copal or other
suitable agglutinant with or without gutta percha or rubber and compressed whilst
subjected to heat under. a very great pressure to the required density substantially
as described.
