Abstract
Abstract Apparatus for imparting to one or more workpieces a compound rotary motion about two intersecting axes simultaneously which comprises a stationary disc, an opposed rotatable disc, workholding assemblies between said discs, each work-holding assembly comprising a wheel rotatable by said rotatable disc about an axis intersecting the axis of rotation of said rotatable disc and means for holding a workpiece including a permanent magnet; and means for causing rotation of said wheels and workpieces by rotating said rotatable disc in contact with said wheels while said wheels are in contact with said stationary disc.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
162 words
Apparatus for imparting a compound motion to at least one workpiece comprising: a frame; a horizontally extending, nonrotatable shaft comprising a portion of said frame; a plurality of work-holding assemblies extending radially outwardly from said shaft; means rotatably mounting said work-holding assemblies on said shaft; means carried by each of said work-holding assemblies for receiving workpieces; a pair of opposed, axially spaced annular members carried by said frame and movable axially with respect to each other, one of said annular members being rotatably mounted relative to the other of said annular members about a first axis coincident with said shaft; each of said workholding assemblies having means interposed between said annular members and engagable therewith for bodily revolving said workholding assemblies about second axes, respectively, extending in directions perpendicular to said first axis, upon rotation of said rotatable annular member; means for moving said annular members axially with respect to each other; and drive means for rotating said rotatably mounted annular member.
Claim 2
Dependent Claim
162 words
Apparatus for imparting a compound motion to at least one workpiece comprising: a frame; a horizontally extending, nonrotatable shaft comprising a portion of said frame; a plurality of work-holding assemblies extending radially outwardly from said shaft; means rotatably mounting said work-holding assemblies on said shaft; means carried by each of said work-holding assemblies for receiving workpieces; a pair of opposed, axially spaced annular members carried by said frame and movable axially with respect to each other, one of said annular members being rotatably mounted relative to the other of said annular members about a first axis coincident with said shaft; each of said workholding assemblies having means interposed between said annular members and engagable therewith for bodily revolving said workholding assemblies about second axes, respectively, extending in directions perpendicular to said first axis, upon rotation of said rotatable annular member; means for moving said annular members axially with respect to each other; and drive means for rotating said rotatably mounted annular member.
Claim 3
Dependent Claim
53 words
Apparatus according to claim 1 wherein said interposed means comprises a wheel, frictionally driven by said rotatably mounted annular member, said wheel being rotatably mounted on a shaft connected at its inner end to said rotatable mounting means and extending radially therefrom, said radial shaft being coincident with one of said second axes.
Claim 4
Dependent Claim
40 words
Apparatus according to claim 1 wherein said means for moving said annular members axially comprises means engaging said non-rotatable shaft and another portion of said frame and adapted to move said shaft axially with respect to said other frame portion.
Claim 5
Dependent Claim
66 words
Apparatus according to claim 1 wherein said drive means includes: a motor, a pair of sprockets and chain means; one of said sprockets being operatively connected to said motor for rotation thereby, said other sprocket being mounted on a rotatable tube carried by said frame concentrically about said non-rotatable shaft and rigidly secured to said rotatably mounted annular member, and said chain means engaging said sprockets.
Claim 6
Dependent Claim
24 words
Apparatus according to claim 1 wherein at least one of said annular members comprises an annular cup-like element having an annular disc secured therein.
Claim 7
Dependent Claim
22 words
Apparatus according to claim 1 wherein each of said work-holding assemblies includes at least one permanent magnet for holding a workpiece thereto.
Claim 8
Dependent Claim
53 words
Apparatus according to claim 3 wherein said interposed means comprises a wheel frictionally driven by said rotatably mounted annular member, said wheel being rotatably mounted on a shaft connected at its inner end to said rotatable mounting means and extending radially therefrom, said radial shaft being coincident with one of said second axes.
Claim 9
Dependent Claim
65 words
Apparatus according to claim 3 wherein said drive means includes: a motor, a pair of sprockets and chain means; one of said sprockets being operatively connected to said motor for rOtation thereby, said other sprocket being mounted on a rotatable tube carried by said frame concentrically about said non-rotatable shaft and rigidly secured to said rotatably mounted annular member, and said chain meansengaging said sprockets.
Claim 10
Dependent Claim
66 words
Apparatus according to claim 7 wherein said drive means includes: a motor, a pair of sprockets and chain means; one of said sprockets being operatively connected to said motor for rotation thereby, said other sprocket being mounted on a rotatable tube carried by said frame concentrically about said non-rotatable shaft and rigidly secured to said rotatably mounted annular member, and said chain means engaging said sprockets.
Claim 11
Dependent Claim
24 words
Apparatus according to claim 9 wherein at least one of said annular members comprises an annular cup-like element having an annular disc secured therein.
