MAGNETIC KINETIC SCULPTURE
Abstract
A magnetic kinetic amusement device and sculpture in which a
pair of permanent magnets are separately supported by spring wires
above a supporting base in spaced, substantially opposed relation
with their corresponding poles adjacent each other, the supporting
wires being shaped to enable universal random movement of the
magnets relative to each other, and to support the magnets with
their fields of force interlapping to effect prolonged random
movement of the magnets due to repulsion of their corresponding
poles when one magnet is forcibly moved relative to the other, and
released.

Description
SUMMARY
Mobiles are known as kinetic sculpture, comprising delicately
balanced units suspended by wire or string, so that the units will
move relative to each other when stirred by a breeze.
One of the objects of the present invention is the provision of
magnetic kinetic sculpture comprising units that include permanent
magnets, and which units are supported on spring wires that are
constantly yieldably urging the units toward a static, directly
opposed, spaced relation, in which their corresponding poles face
each other, but which units are precluded from reaching said static
position by the repulsion of corresponding poles, thus resulting in
a prolonged, random movement of the magnetic units relative to each
other.
Another object of the invention is the provision of a magnetic
kinetic sculpture in which the moving force is the combination of
the tension force of springs tending to move a pair of permanent
magnets having their corresponding poles facing each other, to a
directly opposed, spaced, relation, and the repulsive force of said
corresponding poles operating to keep the magnets out of said
opposed relation, resulting in a prolonged random universal
movement of the magnets toward and away from each other at each of
the opposite sides of the space between the magnets.
A still further object of the invention is the provision of a
magnetic kinetic sculpture that includes the foregoing objects
including provision physically preventing sufficient proximity of
the opposite attracting poles of the magnets to draw the opposite
poles together during movement of the magnets relative to each
other.
Other objects and advantages will appear in the description and
drawings.

DETAILED DESCRIPTION
Referring to FIG. 1, a base 1 of any suitable material, size, and
configuration is provided. The weight, size, and material of the
base should be such as to support the device, as a whole,
stationary on a supporting surface against tipping over when the
elements carried thereby are static or when in movement or when
initially actuated to start movement.
A pair of upstanding spring wires 2, 3 are stationarily secured at
their lower ends to said base, it being understood that the word
"base" is intended to include any element rigid with said base,
whether integral with the latter or added. In FIG. 1 the wires 2, 3
extend vertically into spaced openings formed in the main body of a
base along a horizontal line in a vertical plane bisecting the
base. Said wires are preferably of the same gauge of tempered music
or piano wire, hence of spring steel adapted to retain any bends or
conformation given the wire.
Wire 2 is bent at a point 5 adjacent its lower end to provide a
horizontally extending portion 6 that terminates in a return bend
7.
The lower end portion 4 of wire 2 extends vertically upwardly from
base 1 for a relatively short distance, and is formed with a lower
bend at point 5 therealong to provide a horizontally extending
lower section 6 that extends in a direction away from wire 3.
Section 6 terminates in an acute return bend 7 providing an upper
section 8 that extends back to an upper bend 9 that is at a point
above the bend 5, and from bend 9 the major length 10 of the wire 2
extends vertically upwardly to a magnet 13.
Magnet 13 may be a circular or cylindrical disclike section of a
bar magnet having a central axis perpendicular to the plane of the
disc with north and south poles on said axis at opposite sides of
the disc, and the upper end of length 10 of the wire 2 is rigidly
connected with magnet 13 centrally of the lower side.
Magnet 13 is preferably encased in nonmagnetic material, such as a
suitable plastic, to provide an outer disc-shaped covering 14
coaxial with the magnet 13.
The magnet 13, as shown in FIG. 1, is horizontally disposed, and
the terminal upper end of length 10 of wire 2 may extend into, and
be bonded to the plastic 14 or nonmagnetic material extending over
the underside of the magnet, although it may be secured directly to
the magnet.
The nonmagnetic cover 14 may be relatively thin where it extends
over the upper side of the magnet, but a rim 15 of said material
extends radially outwardly of the magnet a substantially greater
distance.
The upper and lower surfaces of cover 14 may be convexly rounded,
and rim 15 may be formed with an annular radially outwardly opening
recess 16.
Wire 3 extends vertically upwardly, as at 17, from base 1, and
adjacent its upper end it is formed with a lower bend 18 that is
similar to bend 9, thereby providing a laterally extending lower
section 19 of said wire, similar in inclination to section 8 of
wire 2.
Section 19 terminates at its outer end in a return bend 20 that is
similar to return bend 7 of wire 2, providing an upper return
section 21 that is at an acute angle relative to lower section 19,
and which upper section 21 has a short terminal end portion 22 that
extends vertically downwardly. This terminal end section 22 is
secured at its outer end to a magnet generally designated 23, which
magnet may be the same as magnet 13, except that is is inverted.
The section 21 extends into the outer nonmagnetic cover of the
magnet, centrally thereof, and may be bonded thereto, or to the
central portion of the magnet itself. The structure of the magnet,
including its cover, has the same numerals as used for magnet 13.
The corresponding poles of magnets 13, 23 face each other.
The wires 2, 3 shown in FIGS. 1, 2, including the bends therein,
are the same vertical plane, or approximately the same plane (FIG.
2).
Assuming the magnets are not on the ends of the springs or wires 2,
3, the preferred positions of the wires on base 1 are such that the
sections 10, 22 of the wires 2, 3 would be in alignment, and spaced
apart a sufficient distance that the magnets 13, 23, including
their coverings, when secured on the free ends of sections 10, 22
would also be spaced apart, but sufficiently close to each other so
their corresponding poles will repel each other to prevent their
coaxial alignment when at rest. The rims 15 of nonmagnetic material
function to space the magnets a sufficient distance apart to
prevent them from being held together by the attraction of their
unlike poles in the event axial movement of the magnets should
accidentally position the magnets in side-by-side relation.
The center of gravity of the magnets 13, 23 is preferably
substantially over the center of the base 1 to insure stability of
the device when the magnets are static, and when in motion, and the
base may be provided with conventional, adjustable levelling feet
24 to compensate for their imbalance due to the force of
gravity.
In FIGS. 4, 5, a base 27 is similar to base 1, and is adapted to be
positioned on a table or other support.
Spring wires 28 are secured at their lower ends to base 27. These
springs or wires have the same characteristics as wires 2, 3 and
may be in the same relative positions as wires 2, 3 at their lower
ends.
Said wires extend upwardly from the base and wire 28 may have one
or more artistic bends or curves 30 intermediate the base 1 and its
terminal upper end.
Wire 29 may also have one or more bends or different curves 31
intermediate base 27 and its terminal upper ends.
The terminal upper ends of wires 28, 29, respectively, have magnets
33, 34 secured thereto, which magnets may correspond to magnets 13,
23 in structure. Said wires 28, 29 support magnets 33, 34 in spaced
relation with their corresponding poles facing each other, and were
it not for the repellent force of the corresponding poles, said
magnets would be in substantially axial alignment. The spacing
between the magnets is such that the repellent force of the poles
prevents their movement to coaxial alignment. As in the example of
FIGS. 1, 2, the magnets may have universal random movement, i.e.,
they may move toward and away from each other in any direction, but
always against the resistance of the springs supporting them and
tending to move them back toward coaxial alignment. Either or both
magnets may move in circular and arcuate directions as well as
straight paths.
The wires or springs supporting the magnets may assume many
different artistic contours providing for creative sculptures
appealing to the aesthetic senses of the observer.
In operation, upon forcibly springing one or both wires 2, 3 or 33,
34 to one or opposite sides and releasing them, the magnets will
have a random movement which is completely unpredictable, the
resiliency of the spring wires tending to return the magnets to
coaxial alignment and the similar poles on the magnets repelling
such return. Upon the forces of the springs and the magnetic fields
of the magnets reaching a balance, the magnets will come to rest,
with their axes offset, although tremors transmitted to the magnets
through the base will cause relative movement of the magnets
distinguishable from movement of mere spring-supported, nonmagnetic
elements.
While the structure of FIGS. 1, 2 is preferable due to the fact
that the force of the spring supports is not expended in moving the
magnets upwardly against the force of gravity as in FIGS. 3, 4,
upon downward movement of the magnets, and an adjustment of the
magnets relative to each other is readily effected, nevertheless
the action is quite similar. The forming of the wires to provide
universal movement is quite important. The gauge of the wires,
their resiliency, and the strength of the magnets are features that
may vary according to the desired effects.
The wires themselves may be of any suitable material having the
resilient characteristic of steel piano or music wire and the
magnets are preferably of the type having at least the character of
those known in the trade as ALNICO magnets, each having oppositely
outwardly facing sides of opposite polarity.
The magnets, or the nonmagnetic material, or both, may assume
different external contours to represent abstract or realistic
objects, provided a sufficient field of magnetic force is
present.
