Improvements in the Manufacture of Golf Balls.
I, JEANNIE MACNEIL, of 105, Houston Street, Kinning Park, Glasgow, Golf Ball
Maker, do hereby declare the nature of this invention to be as follows:-
This invention relates to golf balls and it consists in manufacturing them from a
composition composed of glue or gelatine, cork or (and) leather and bi-chromate
of potash. When manufacturing the balls a certain amount of water or an acid;
preferably acetic acid is added to the composition.
The cork is preferably pulverized or ground. Pieces of cork may however be
used.
The leather is preferably pulverized or ground. Pieces of leather may however.
be used.
The composition is pressed in a mould to the desired shape and then allowed
to season.
Dated this 16th day of September 1897.

Improvements in the Manufacture of Golf 'Balls.
I, JEANNIE MACNEIL, formerly of 105, Houston Street, Kinning Park, now
405, Eglinton Street, Glasgow, Golf Ball Maker, 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 :-
This invention relates to golf balls and it consists in manufacturing them from a
leather, and bi-chromate of
and
or
composition composed of glue gelatine, cork
and
or
potash. When manufacturing the balls a certain amount of water or an acid,
preferably acetic acid, is added to the composition.
The cork is pulverized or shredded, or it may be in shavings, and is prepared
before mixing with the other ingredients.
The leather is cut in pieces about the size of coffee beans and is roasted in a
cylinder, such as is used for roasting coffee beans, so that it becomes crisp and hard
and can be readily ground into powder in a coffee or like mill.
and
and
The glue gelatine is soaked in acetic acid water until soft when it can be
or
ог
easily melted by heat. Whilst it is warm the other ingredients are mixed with it by
hand or in any convenient known mixing machine.
PQ/1

page_text: The bi-chromate of potash is dissolved in hot water and some of the solution is
added to the mixture while mixing.
In 100 parts of the mixture, by weight, there may be from 25 to 35 parts of glue
gelatine and 1 to 3 parts of bi-chromate of potash, the remainder being cork.
and
or
If so desired leather may be substituted for cork or only a percentage of leather
may be added.
I have given the above proportions by way of example and as an indication of what
I have found to answer well in practice but the proportions can be altered to suit
different requirements as regards hardness or softness, density, or weight.
"
I employ metal golf ball moulds to form the balls, the interior surfaces of the
moulds being well oiled with raw oil or grease. A sufficient quantity of the mixture
to make a ball is placed in the female half of each mould and then the male half is
inserted in place and the mould "subjected' to 'hydraulic pressure in an hydraulic
press. After the balls have been subjected to pressure for not less than a minute
they are removed. By pressing them in this manner I can press two or more moulds
at a time, according to the size of the press, thereby manufacturing the balls quickly.
If so desired instead of placing some of the bi-chromate of potash solution in the
mixture the balls can be steeped in the solution after they are moulded; or if so
-desired some of the solution can be added to the mixture and the balls also subse-
quently steeped in the solution.

'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
consider novel and desire' to claim is:
...J.
Golf balls made of the materials and in the manner substantially as hereinbefore
escribed.
