Abstract
Abstract A magnetically operated rotative amusement device or unit of a substantially self-starting nature has a see-through or transparent container or bowl-like support base provided with a lower, centrally disposed, pivot-receiving socket. A spinner has a pivot pin adapted to rest in the socket and to extend upwardly towards an open mouth portion of the support base. The support base has either an inner collar or a relatively narrow bowl to support the spinner in an upright, slightly tilted position in a ready-to-operate relation therein. A dome-shaped lid is used to close-off an open mouth portion of the support base and has a centrally, downwardly extending, permanent magnet supported in a vertically adjustable relation in which it is slightly spaced from and aligned with a second and opposing magnet carried by an upper end of the spinner. The spinner may be caused to rotate or spin by moving the lid in an angular relation to a closing-off position from a side of the bowl that is opposite to a tilted positioning of the spinner within the bowl. If the lid is in place or in a permanently mounted position with respect to the bowl, then spinning movement may be effected by slightly tilting the support base. Rotation of the spinner thus accomplished will continue for an effective period of approximately two or three minutes using a pivot pin on the spinner part and the socket therefor of a relatively hard and smooth material of minimized frictional resistance, for example, a tapered-end steel pivot pin and a socket of glass.

Independent Claim
171 words
A magnetically controlled rotating spinner device which comprises, a hollow container having a vertically extending side wall and bearing socket therein at its lower end portion, a spinner part having upper and lower end portions, said spinner part having pivot means at its lower end portion to rotatably seat within said socket, said spinner part being adapted to extend substantially vertically upwardly within said container side wall and to be substantially uprightly supported when not operating within said container, a cross-extending overhead support means positioned to extend across said container and rest on said side wall, a first magnet carried in a suspended relation on said support means, a second magnet carried by the upper end portion of said spinner and having one pole facing a pole of opposite polarity of said first magnet and in a critically spaced relation with respect thereto, such that manually induced rotative movement of said spinner will be furthered by a substantially balanced spaced-apart magnetic force interaction of opposite magnetic polarities exerted by said magnets.
Claim 2
Dependent Claim
171 words
A magnetically controlled rotating spinner device which comprises, a hollow container having a vertically extending side wall and bearing socket therein at its lower end portion, a spinner part having upper and lower end portions, said spinner part having pivot means at its lower end portion to rotatably seat within said socket, said spinner part being adapted to extend substantially vertically upwardly within said container side wall and to be substantially uprightly supported when not operating within said container, a cross-extending overhead support means positioned to extend across said container and rest on said side wall, a first magnet carried in a suspended relation on said support means, a second magnet carried by the upper end portion of said spinner and having one pole facing a pole of opposite polarity of said first magnet and in a critically spaced relation with respect thereto, such that manually induced rotative movement of said spinner will be furthered by a substantially balanced spaced-apart magnetic force interaction of opposite magnetic polarities exerted by said magnets.
Claim 3
Dependent Claim
29 words
A spinner device as defined in claim 1 wherein said first and second magnets exert substantially the same magnetic force in a balanced relation with respect to each other.
Claim 4
Dependent Claim
33 words
A spinner device as defined in claim 1 wherein said socket is of a hard material having a relatively low frictional characteristic, and said pivot means also, has a relatively low frictional characteristic.
Claim 5
Dependent Claim
72 words
A spinner device as defined in claim 1 wherein means adjustably mounts said first magnet on said support means to adjust its spaced relation with respect to said second magnet to provide a spaced magnetic force relation therebetween such that said first magnet will not draw said second magnet into abutment therewith and that magnetic forces exerted by said magnets will further rotation of said second magnet and thus of said spinner.
Claim 6
Dependent Claim
56 words
A spinner device as defined in claim 1 wherein, said container side wall is of upwardly open-end bowl shape, said support means is a lid mounted over the open end of said bowl-shaped side wall, and a threaded adjustable pin extends substantially centrally downwardly through said lid and carries said first magnet on its downward end.
Claim 7
Dependent Claim
83 words
A spinner device as defined in claim 1 wherein, said side wall has means adapted to support said spinner in a slightly off-vertical tilted relation when said spinner has ceased to rotate, said spinner is adapted to move into a fully vertically aligned and spaced-apart relation with said first magnet when an initial manual actuation is effected on said spinner, and said spinner is thereafter adapted to continue to rotate in such an aligned relation during spaced-apart magnetic force interaction between said magnets.
Claim 8
Dependent Claim
172 words
A magnetically operated rotating spinner device which comprises, a bowl-shaped supporting base having a substantially centrally disposed bearing socket therein and a rim defining an upper open mouth portion thereabout, a spinner part having a pivot means at its lower end adapted to be rotatively positioned within said bearing socket, a lid adapted to be removably mounted in a seated position on said rim over the open mouth portion of said supporting base, a first magnet carried in a downwardly suspended relation by said lid, a second magnet carried by an upper end of said spinner part, said first and second magnets having opposed poles facing each other in a spaced-apart substantially aligned relation when said lid is moved into its seated position on said rim, and said magnets having opposed poles in their spaced-apart relation adapted to enhance upright rotative movement of said spinner and its said pivot means within said socket when said lid is moved to a seated position with respect to the open mouth portion of said bowl.
Claim 9
Dependent Claim
172 words
A magnetically operated rotating spinner device which comprises, a bowl-shaped supporting base having a substantially centrally disposed bearing socket therein and a rim defining an upper open mouth portion thereabout, a spinner part having a pivot means at its lower end adapted to be rotatively positioned within said bearing socket, a lid adapted to be removably mounted in a seated position on said rim over the open mouth portion of said supporting base, a first magnet carried in a downwardly suspended relation by said lid, a second magnet carried by an upper end of said spinner part, said first and second magnets having opposed poles facing each other in a spaced-apart substantially aligned relation when said lid is moved into its seated position on said rim, and said magnets having opposed poles in their spaced-apart relation adapted to enhance upright rotative movement of said spinner and its said pivot means within said socket when said lid is moved to a seated position with respect to the open mouth portion of said bowl.
