PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Golf Balls and Balls for
like uses.
I, CHARLES JAMES GRIST, of 20, Gracechurch Street, in the City of London,
Electrical Engineer, do hereby declare the nature of this invention to be as
follows:-
I take linseed or other drying oil and heat it up to at least 400° F. adding
litharge or other suitable drying agent taking care that it does not boil con-
tinuously for more than six hours at any one time the whole of which time the
oil is kept continuously in motion by suitable apparatus arranged either attached
or conveniently adjacent to the vessel containing it.
I then take a fibrous substance such as hemp, jute, cotton or suitable animal
fibre or other fibrous substance in which the fibres are or can be made to be
distinct and similar.
I then subject the fibres to a cleaning process such as carding.
The fibres now are spread and subjected to a drying process such as by means
of heated air propelled or drawn through them in order to remove as much as
possible any trace of aqueous moisture.
The oil having regained its normal temperature I take the fibres which have
been treated as above described, and immerse them in such oil immediately re-
moving them and placing them in a hydro-extractor or other suitable machine
for the purpose of extracting as much as possible all the superfluous oil, which
is then drained away.
The fibres will now be found to have small globules of partially oxidised oil
adhering at intervals on each fibre.
Then the fibres are spread loosely on wire gauze or netting and a current of
heated air is made to pass through them by means of a fan or other suitable
machine and in order that all the globules of oil in the fibres may be brought
into contact with the heated air as much as possible, the fibres must be turned
or redistributed in the netting about every hour. By these means nearly every
globule of oil adhering to the fibres is thoroughly oxidised and dried. When
this is accomplished I take the fibres and redip in the oil and when taken out
of the hydro-extractor it will be found that more globules of oil are adhering
to the fibres in the vacant spaces in between the former and already oxidised
particles. I repeat the drying process. A third and last time dip the fibres
and proceed as before. I find that it is not expedient to dip more than three
times because most of the fibres being covered with globules of oxidised oil,
hould another dip take place the unoxidised oil might coat and spread on the
xidised oil if this happens the drying process cannot be thorough as the heated
ir would not be able to play upon the whole of the unoxidised oil and oxidation
eing imperfectly accomplished the resulting material would be worthless.
The fibres are now placed in masticating or grinding rolls, of different

condition.
Then the material is placed in crushing rolls, which must not be heated, and

I, CHARLES JAMES GRIST, of 20, Gracechurch Street, in the City of London,

manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:—

lead or other suitable paint and when dry are ready for use.
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 manufacture of golf balls and balls for like uses from oxidized oil and
fibre treated and prepared as and for the purpose herein before set forth.
2. As a new article of manufacture a golf ball, or ball for like uses prepared
from oxidized oil and treated fibre according to the process hereinbefore set
forth.
