PROVISIONAL SPECIFICATION.
Improvements in Balls for Use in Playing Polo and other like Games:
We, THOMAS BINNIE DRYBROUGH, of 207, Piccadilly, London, W., Gentleman,
and Sir ALBERT ALTMAN, of 64, Aldersgate Street, London, E.C., Knight, do
hereby declare the nature of this invention to be as follows:-
-
This invention relates to balls used in playing the games of polo, hockey and
other like games, and has for its object improvements whereby great durability
is combined with the requisite amount of elasticity, while a suitable size and
weight is maintained.
Our improved ball is built up in the following manner:-Around a suitable
foundation or core of a material possessing the necessary amount of resistance,
cohesion and of a suitable weight, we place an elastic casing made of a resilient
material, the whole being then enclosed in an outer canvas or string, waterproof
cover, which gives the finished ball the requisite amount of cohesion, and renders
it impervious to water-the absorption of which would vary its weight and be
otherwise detrimental.
In carrying out our invention we may use a foundation or core of cork or
other suitable material which may or may not be hollow and may or may not
be weighted; and, the elastic cover may consist of threads or fibres of rubber or
the like wound round the core until a suitable thickness has been reached;
or, the said elastic cover may consist of pieces of the same or a like material
having the form of segments of a hollow ball of the requisite size and thickness.
These parts may be vulcanized, cemented or otherwise joined up, or they may
be held in their respective places by the outer cover.
Or, thirdly, the elastic cover may be applied by immersing the core in a
resilient material while such material is in a more or less fluid condition.
The outer cover may be composed of waterproof canvas or other tenacious
material which is sewn or otherwise attached tightly around the ball; or, instead
of this the outer cover may consist of string which is tightly knitted or otherwise
suitably applied in a manner well-known.
In this latter case, the ball is subsequently waterproofed by vulcanizing or
otherwise applying rubber or other suitable material, or by any other well-known
or suitable means.

page_text: 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 balls adapted for use in playing the games of polo,
hockey and other like games, and has for its object improvements whereby great
durability is combined with the requisite amount of elasticity, while a suitable
size and weight is maintained.
Our improved ball is built up in the following manner:-Around a suitable
foundation or core of a material possessing the necessary amount of resistance,
cohesion and of a suitable weight, we place an elastic casing or envelope made
of a resilient material, the whole being then enclosed in an outer canvas, string
or other suitable cover, which gives the finished ball the requisite amount of
cohesion.
The outer cover may be suitably waterproofed before or after it is applied to
the ball, so as to render it impervious to water-the absorption of which would
vary the weight of the said ball and be otherwise detrimental.
We will now more particularly describe our invention with the aid of the
accompanying drawings, of which Figs. 1 & 2 show two constructions of our
improved ball, and Fig. 3 illustrates a detail hereinafter referred to.
In the construction shown in Fig. 1, a solid core or foundation, a, is employed,
which may be composed of cork, wood or the like, and may be loaded, as indicated
by the dotted lines at b, in order to regulate its weight.
'
This core is next enclosed between walls c, of a resilient material such as
rubber, gutta percha or other like substance, which may be applied to it in a
plastic condition, by vulcanization, in segments, by winding (such as rubber
threads) or any other convenient well-known manner.
The whole is then enclosed in an outer envelope d, composed of a tenacious
and preferably waterproof fabric such as canvas, which is stitched tightly, or
otherwise suitably secured around the ball.
According to the construction shown in Fig. 2, the core a is hollow and made
in halves and may be of a metal, such as aluminium, or other suitable material,
this core a is placed between similar halves c of a resilient material, the whole
being then held together by a canvas or other suitable cover d.
In this construction is shown an outer waterproof surface e such as of rubber.
Instead of using canvas or other close fabric a string cover (see Fig. 3) may
be employed instead of that shown at d in the other figures.
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. A ball, consisting of a core or foundation, surrounded by a stratum of
resilient material and the whole contained in an outer casing, substantially as
described and for the purposes set forth in the specification.
2. The combination and arrangement of parts constituting an improved ball
for use in playing polo and other like games, all substantially as described in
the specification and shown in the drawings.
Dated this 9th day of February 1900.
