PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Hollow Balls in Aluminium
or Aluminium Alloys, or by any of the Metals for Golf, Tennis,
Cricket, or Billiard Playing.
PATRICK BARRY, 4 Dorothy Road Clapham Junction Journalist and Author I do
hereby declare the nature of this invention to be as follows :-
The present improvements consist in the production of the hollow balls in
aluminium or in aluminium alloys etc. without holes, either by closing the spindle
holes of the cast balls by any well known means or by the production of the balls
without holes preferably by melting fixed quantities of the metal over a fire in
revolving cylinders; or by the injection of fixed quantities of metal into hollow
cylinders by compressed air, or by hydraulic means, or by pumping as is well known
in type casting or by other known forms of pressure the hollow cylinders constructed
to turn out the finished balls.
The novelties in these improvements are:-
First, a hollow aluminium ball admitting of lesser weight if desired than the solid
ball in present use.
Second, a hollow aluminium ball with or without openings which does not require
painting.
Third, a hollow aluminium ball which admits of golf playing in semitropical and
tropical countries the high temperatures of those countries rendering the present ball
unsuitable.
Improvements in the Manufacture of Hollow Balls in Aluminium
or Aluminium Alloys, or by any of the Metals for Golf, Tennis,
Cricket, or Billiard Playing.
PATRICK BARRY 4 Dorothy Road Clapham Junction Journalist and Author 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 :----
Aluminium in its so called pure or commercial condition is a dull and relatively
weak metal destructively acted on by caustic soda or hydrochloric acid and therefore
for strength and resiliency alloys are essential whether to retard the destructive action
of hydrochloric acid or caustic soda or to impart the resiliency essential for use in the
aforesaid games.
Preferring casting in sand or chills to any other method with suitable cores for the
thickness of metal desired as is well known in foundry practice I alloy pure or
commercial aluminium with any metal or substance harder than the so-called pure or
commercial aluminium by increasing or diminishing the percentage of the hardening
n

excellent resilient ball may be obtained by use of the following formula but others
may be used-
100 parts pure or commercial aluminium 5 parts of brass which may be hard or
soft as will best serve the required purpose.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare what I claim is :-
1. Casting hollow in sand or in chills any of the foregoing balls.
2. Hollow balls in aluminium or aluminium alloys or by any of the metals for golf,
tennis, cricket or billiard playing.
