RANDOM SELECTION BALL FORMED OF CONCENTRIC SPHERES
Abstract
An amusement ball having a hollow outer shell totally or
partially formed of transparent material. The shell is provided
with a plurality of indicia which may be randomly disposed. The
ball also includes an inner sphere substantially concentrically
disposed, being rotatably maintainable within the outer shell. The
inner sphere is provided with a marker index at one point and a
diametrically opposed counterweight, so that the inner sphere when
disturbed will come to rest with its index mark uppermost, being
disposed adjacent to one of the indicia of the outer shell.

Description
BACKGROUND OF THE INVENTION
Many games and amusement devices require the selection of an
element from among a plurality of elements. The ball of the present
invention provides for the selection of one out of a large number
of elements. The ball provides for this selection in a simple and
relatively effortless and automatic manner. It provides for a
random selection and is adaptable to a variety of different
elements such as numbers, letters, words or the like and is
adaptable to a large variety of games.
The element selected by means of the ball may be used directly for
indicating scoring points, the formation of sequences of numbers,
words or the like. Although the elements on the ball may themselves
be words or the like, simple elements may be used to furnish
indicators for the determination of answers, fortunes or the like.
The ball, therefore, is useable to furnish enjoyment in a large
variety of ways and the user may add to his enjoyment by devising
various methods of employment.
SUMMARY OF THE INVENTION
The amusement ball of the present invention includes a hollow outer
shell having a plurality of marks which may be randomly disposed,
and is at least partially transparent. The marks may be numbers,
letters, words, figures, objects, or the like. Substantially freely
rotatable within the hollow shell is a sphere, the sphere being
provided with an index mark and a counterweight located
diametrically opposite to the index mark so that when disturbed the
sphere will come to rest with the index mark substantially
uppermost. In the rest position, the index mark is disposed
adjacent to one of the marks of the outer shell.
Accordingly, an object of the present invention is to provide an
amusement ball which overcomes the disadvantages of the prior
art.
Another object of this invention is to provide a ball which may be
used for education, entertainment, or amusement purposes.
A further object of this invention is to provide a ball which in
addition to being suitable for the usual types of play such as
throwing, catching, bouncing and the like, includes within its
hollow interior an indicator which is movable relative to the
shell, being visable from outside of the ball.
A still further object of this invention is to provide a ball of
the above type in which the indicator when observed by the player
or players forms the basis of a game, the indicator being
associated with markings on the shell.
Other objects and advantages of this invention will appear
hereinafter.
DESCRIPTION OF THE DRAWINGS
For a fuller understanding of the nature and the objects of the
present invention reference should be made to the following
detailed description in connection with the accompanying drawings,
in which:

FIG. 2 is a sectional view of the ball of the present invention
taken along line 2--2 of FIG. 1;
FIG. 3 is a sectional view of the ball of the present invention
taken along line 3--3 of FIG. 2; and
FIG. 4 is a sectional view similar to the view of FIG. 2, showing
another embodiment of the present invention.
DESCRIPTION OF THE INVENTION
The ball 10 of the present invention has an outer shell 12 made of
rubber, plastic or similar polymeric material. The shell 12 is in
part or totally transparent, and is provided with a plurality of
marks 16, shown in FIG. 1, as a random arrangement of letters and
numbers. It is readily seen that these marks may be of various
types and variously placed and may also include various
combinations of types.
Rotatably mounted within shell 12, pivoted at diametrically
opposite points or members 24 and 26, a suspension ring 22 is
provided. The pivot members 24, 26 preferably are conventionally
secured to the shell 12 and have projecting portions 25, 27
extending through apertures formed in the ring 22. These apertures
are spaced 180.degree. apart.
Rotatably mounted upon suspension ring 22 and pivoted at two
diametrically opposite points or members 28 and 30, inner sphere 14
is provided. The sphere pivoting points or members 28, 30 are
located as hereinbefore stated at diametrically opposite points on
ring 22, said diameter being perpendicular to the diameter defined
by the mounting ring pivoting points or members 24, 26. The pivot
members 28, 30, are similar to members 24, 26. The members 28, 30
preferably are conventionally secured to the inner sphere 14 and
have projecting portions 29, 31 extending through apertures formed
in the ring 22. These apertures are also spaced 180.degree. apart,
so that the ring 22 has an aperture every 90.degree., these
apertures being equally spaced as set forth above.
Thus, while suspension ring 22 is free to rotate in one plane only
with respect to outer shell 12, the inner sphere 12 is free to
rotate in any plane whatsoever with respect to outer shell 12
because of its gimbal arrangement.
A point of inner sphere 14 is provided with an index mark 18.
Diametrically opposite to index mark 18, counterweight 20 is
provided. If the ball 10 is disturbed, as for instance by rolling
along a surface and then allowed to rest, the inner sphere 14 will
because of the inertial forces involved rotate independently of the
ball 10 and come to rest at a position relative to the outer shell
12 which will differ from its position relative to shell 12 at the
start of the disturbance. Sphere 14 will, because of the action of
the counterweight 20, come to rest with the index mark 18
uppermost.
As is readily understood, the index mark 18 will now locate a point
on the outer shell 12 which is different from the point located
prior to the disturbance. If the outer shell 12 is constructed of a
transparent material or if a transparent portion of the shell 12 is
now uppermost, the ball 10 has now operated to select one of the
plurality of marks 16. As indicated above, the index mark 18 can
locate or select any mark 16 of the outer shell 12 because of the
free rotation provided by the gimbal arrangement. FIG. 4 discloses
a ball 10A forming another embodiment of the present invention
which illustrates another method for suspending a sphere 14A inside
a shell 12A permitting the sphere 14A to rotate and come to rest in
a position independent of the position of the shell 12A.
The diameter of the inner sphere 14A is less than the inner
diameter of the shell 12A. This difference provides flotation space
32. A flotation liquid 34, chemically inert with reference to the
material of which the ball 10A is constructed, is introduced into
the flotation space 32 and partially fills the space 32. The liquid
34 selected has a density which will enable the sphere 14A to float
at a predetermined height within the flotation space 32, preferably
one where the inner sphere 14A and the outer shell 12A will be
concentric. The methods and nature for determining this as well as
the laws of flotation of bodies in liquids are of course widely
understood and generally available.
If ball 10A is now rolled, because of the action of the
counterweight 20A and the inertial, frictional and gravitational
forces involved, the sphere 14A will oscillate for a short period
of time and then will come to rest with its index mark 18A
uppermost to indicate or select one of the marks on the shell as
hereinbefore explained, wherein the index mark 18A is diametrically
opposite to the counterweight 20A.
Numerous alterations of the structure herein disclosed will suggest
themselves to those skilled in the art. However, it is to be
understood that the present disclosure relates to preferred
embodiments of the invention which is for purposes of illustration
only, and not to be construed as a limitation of the invention.
