Complete Specification Left, 9th May, 1894-Accepted, 9th June, 1894
PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Golf Balls.
We, FRANCIS EDWARD MATTHEWS Demonstrator in Chemistry, of The Pines,
Englefield Green, and FRANK WILLIAM HARBORD, Analytical Chemist, of
Station Road, Egham, both in the County of Surrey, do hereby declare the nature
of this invention to be as follows:-
In a previous Application No. 98363 we have described a method of covering or
coating golf balls so as to produce a metallic surface thereon. Since the date of
our said prior Application we have discovered that an advantageous manner of
obtaining such a coating is as follows:-
We prefer to take gutta percha and dissolve same in toluol naphtha or other
suitable solvent and employ same as a vehicle for carrying the finely divided metal
with which we then coat the ball one or several times, by which means the metal is
firmly attached to ball by a thin film of gutta percha, the volatile liquid rapidly
evaporating. In some cases we use rosin mastic or other like material dissolved in
suitable solvent instead of gutta percha. Previously to coating as above described
we prefer to have some metallic powder pressed into the surface of the balls during
the moulding. The metals we find most suitable are finely divided silver, aluminium.
or tin or alloys or mixtures of these with copper or copper alloys, but we do not limit
ourselves to any particular metals.
We find it advantageous sometimes to coat the balls by softening the surface by
moistening with some suitable solvent such as toluol or the like and then rubbing
or pressing metallic powder into ball which may then be further coated as above
described if thought necessary.

Improvements in the Manufacture of Golf Balls.
We, FRANCIS EDWARD MATTHEWS, Demonstrator in Chemistry, of The Pines,
Englefield Green, and FRANK WILLIAM HARBORD, Analytical Chemist, of
Station Road, Egham, both in the County of Surrey, 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 :--
In a previous Application No. 98363 we have described a method of covering or
coating golf balls so as to produce a metallic surface thereon. Since the date of
our said prior Application we have discovered that an advantageous manner of
obtaining such a coating is as follows:-
We take gutta percha and dissolve same in toluol naphtha or other suitable
solvent and employ same as a vehicle for carrying the finely divided-metal with
which we then coat the hall one or several times, by which means the metal is firmly
attached to the ball by a thin film of gutta percha, the volatile liquid rapidly
evaporating. In some cases we use rosin, mastic or other like material dissolved in
suitable solvent instead of gutta percha. Previously to coating as above described

page_text: we prefer to have some metallic powder pressed into the surface of the balls during
the moulding. The metals we find most suitable are finely divided silver, aluminium,
or tin, or alloys or mixtures of these with copper or copper alloys, but we do not
limit ourselves to any particular metals.
We may also coat the balls by softening the surface by moistening with some
suitable solvent such as toluol or the like and then rubbing or pressing metallic
powder or foil into the ball which may then be further coated as above described if
thought necessary.
We find by experiment that the metallic powder may advantageously be pressed
into the ball during moulding, and that if the mould be etched on alternate squares
to give alternate bright and dull or broken surfaces on the balls a surface will be
produced somewhat similar to the tinfoil in which tobacco is often wrapped, and
the reflection of the light from the ball will be effective and render the ball readily
visible.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The improvements in the manufacture of golf balls which consist in coating
them with the metallic powder carried by a film which will adhere and harden
on the ball, substantially as described.
2. the improvements in the manufacture of golf balls which consist in rubbing
or pressing a metallic powder upon the ball, substantially as herein before described.
3. The improved golf ball coated with metal in substantially the manner
hereinbefore set forth.
