Method of Colouring Golf Balls.
I JOHN ARCHIBALD Woodhouse Eaves Loughborough Leicestershire Doctor of
Medicine do hereby declare the nature of this invention to be as follows :—

COMPLETE SPECIFICATION.
Method of Colouring Golf Balls.
I, JOHN ARCHIBALD of Woodhouse Eaves near Loughborough in the County of
Leicestershire Doctor of Medicine 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 :-
Incorporating a colouring matter or colouring matters with the material or
materials used in the manufacture of golf balls, so as to do away with the necessity
of painting or repainting their surfaces.
It should be understood that by the terms colour or colouring I include, white or
whitening respectively in addition to all the primary, secondary and tertiary
colours.
It is obvious that there are many materials that may be used, when treated by my
invention, for the manufacture of golf balls; as for instance gutta percha, india
rubber, celluloid, vulcanized fibre and woodite, besides many others too numerous
and not necessary to mention. It is unnecessary for the setting forth of my
invention to describe the processes I should use in the manufacture of golf balls
from all the available materials, so for example I shall confine my description to
some of the processes I employ in the use of gutta percha :
First I simply knead up the ordinary commercial gutta percha, in its ordinary
state or after being cleansed from its impurities, or bleached, or partially bleached,
when in a soft state, with any suitable colouring matter or matters, preferably those
of about a similar specific gravity and then mould the ball in the ordinary
manner.
Second I dissolve the ordinary commercial gutta percha in bisulphide of carbon
or any other suitable solvent or combination of solvents, filter or strain, "fine"
with plaster of Paris or other suitable media, when I incorporate with it in any
desired proportion, any suitable chemicals, colouring matter or colouring matters,
preferably a gum resin, such as gamboge, but I sometimes use white lead whiting,
starch, flour sulphur flowers, or any of the ordinary pigments &c., after which the
ball is moulded in the ordinary manner.
In the same process, sometimes I add a certain percentage of bichloride of sulphur
to the bisulphide of carbon or other solvents & then evaporate the solvents and
proceed as before.
Third I submit the commercial gutta percha or that treated or partially treated
as above described, to the well known process of vulcanizing, namely incorporating
sulphur or other agents, with the material or materials and subjecting the same to
the action of heat.

page_text: Fourth In the manufacture of golf balls by any of the above described processes,
in any material, not necessarily gutta percha I sometimes use a core of different
material or materials not necessarily of the same colour or specific gravity. The
object of this core is to enable me to make the complete ball of the required specific
gravity irrespective of the weight of the exterior material or combination of
materials used, and also to cheapen the manufacture, as the core may be made of a
much cheaper material.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :
1. Incorporating a colouring matter or colouring matters with the material or
materials used in the manufacture of golf balls, by mechanical means, substantially
and for the purpose as hereinbefore described.
2. Incorporating a colouring matter or colouring matters with the material or
materials used in the manufacture of golf balls, by chemical means, substantially
and for the purpose as hereinbefore described.
3. Incorporating a colouring matter or colouring matters with the material or
materials used in the manufacture of golf balls, by a combination of both mechanical
& chemical means, substantially and for the purpose as hereinbefore described.
