Abstract
Abstract An air motion apparatus particularly adapted to move in response to air currents in a fascinating and eye-appealing manner, having a body means formed from a generally frusto-conical container mounted on a spindle means for rotation about the central axis thereof. The body means has formed in or attached to its peripheral side surface a series of elongated vane means which may be slightly curved in transverse cross section and which serve to catch air currents due to wind motion or heat and thereby impart a rotation to the body means about the central axis of the spindle. A plurality of body means mounted on a spindle means, the vane means of each adjacent body means being pitched in opposite directions so that adjacent body means will rotate in opposite directions about the spindle.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
407 words
A decorative air motion apparatus particularly adapted to move in response to air currents in a fascinating and eyeappealing manner, including a stationary, generally vertical spindle, at least two hollow, frusto-conical containers mounted on said spindle, each of said containers being rotatable about a central axis of said spindle, each of said containers being similar in size and shape and having a first surface and a second surface formed by generally horizontal, vertically spaced, generally parallel planes, said first surface having a lesser diametral dimension than said second surface, said first surface and said second surface of each of said containers being joined by a continuous side surface disposed about and connecting a peripheral boundary of each of said first and second surfaces, each of said containers having openings formed in said first and second surfaces near a center portion of each surface to allow said spindle to be inserted into said openings and through each of said containers, each of said containers having an upper sleeve bearing and a lower roller bearing mounted in the opposite openings formed in said surfaces disposed to surround and engage the spindle to reduce friction and allow each of said containers to rotate freely about said spindle, said containers being mounted on said spindle in opposed, mirror-image positions such that their first surfaces face one another while being maintained in a desired spaced relationship on said spindle relative to one another by clamp means mounted on said spindle in stationary positions relative to said spindle and beneath each of said containers, each of said clamp means engaging and supporting said lower roller bearing mounted on each of said containers, each of said containers having a plurality of successively and uniformly spaced flaps disposed around said side surface thereof, each of said flaps being elongated in a generally vertical direction and projecting outwardly relative to said central axis a slight distance from said side surface, each of said flaps being pitched at an angle relative to said side surface of each of said containers such that said flaps on one of said adjacent containers is oriented in an oppositely opening direction relative to said flaps on the other of said containers by reason of the opposed, mirror-image mounting of said containers on said spindle to allow the adjacent containers to rotate about said central axis of said spindle in opposite directions under the influence of air currents impinging upon said flaps.

A decorative air motion apparatus particularly adapted to move in response to air currents in a fascinating and eyeappealing manner, including a stationary, generally vertical spindle, at least two hollow, frusto-conical containers mounted on said spindle, each of said containers being rotatable about a central axis of said spindle, each of said containers being similar in size and shape and having a first surface and a second surface formed by generally horizontal, vertically spaced, generally parallel planes, said first surface having a lesser diametral dimension than said second surface, said first surface and said second surface of each of said containers being joined by a continuous side surface disposed about and connecting a peripheral boundary of each of said first and second surfaces, each of said containers having openings formed in said first and second surfaces near a center portion of each surface to allow said spindle to be inserted into said openings and through each of said containers, each of said containers having an upper sleeve bearing and a lower roller bearing mounted in the opposite openings formed in said surfaces disposed to surround and engage the spindle to reduce friction and allow each of said containers to rotate freely about said spindle, said containers being mounted on said spindle in opposed, mirror-image positions such that their first surfaces face one another while being maintained in a desired spaced relationship on said spindle relative to one another by clamp means mounted on said spindle in stationary positions relative to said spindle and beneath each of said containers, each of said clamp means engaging and supporting said lower roller bearing mounted on each of said containers, each of said containers having a plurality of successively and uniformly spaced flaps disposed around said side surface thereof, each of said flaps being elongated in a generally vertical direction and projecting outwardly relative to said central axis a slight distance from said side surface, each of said flaps being pitched at an angle relative to said side surface of each of said containers such that said flaps on one of said adjacent containers is oriented in an oppositely opening direction relative to said flaps on the other of said containers by reason of the opposed, mirror-image mounting of said containers on said spindle to allow the adjacent containers to rotate about said central axis of said spindle in opposite directions under the influence of air currents impinging upon said flaps.
Claim 3
Dependent Claim
204 words
The air motion apparatus of claim 1 wherein a third hollow, frusto-conical container of similar size and shape to each of said oppositely mounted containers is mounted on said spindle for rotation around said central axis thereof, said third frusto-conical container having a first surface, a second surface of larger diametral dimension than said first surface, and a continuous side surface connecting said first and second surfaces about their peripheries, said third frusto-conical container being maintained in spaced relationship to an adjacent one of said oppositely mounted containers by a third clamp means mounted in a stationary position on said spindle beneath said third frusto-conical container and engaging a lower roller bearing mounted on a surface of said third frusto-conical container, said third frusto-conical container having a plurality of successively and uniformly spaced flaps disposed around its side surface, each of said flaps being elongated in a generally vertical direction and projecting outwardly a slight distance from said side surface, said third frusto-conical container being oriented relative to the immediately adjacent frusto-conical container such that the disposition of said flaps on said side surface of said third frusto-conical container will cause it to rotate in the direction opposite that of said immediately adjacent container.
