Abstract
Abstract A device for inverting a generally planar object which comprises a means for holding said object on its upper plane and its lower plane, means for tilting said object about a fixed axis so that said planes are generally vertical, said object and said holding means being rotatable about the vertical axis of said object 180* and means for re-tilting said object so that said object returns inverted to its original position.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
131 words
A device for inverting a generally planar object which comprises a means for holding said object on its upper plane and its lower plane, a gear motor with a reversible phase for tilting and re-tilting said object about a fixed axis so that said planes are generally vertical when said object is tilted, said motor having an external shaft on which is affixed a sprocketed wheel, a chain affixed at one end to an upper portion of a turntable over which said means for holding said object rotates, said chain affixed at its opposite end to a lower portion of said turntable, said chain being engaged on the sprocket teeth of said sprocketed wheel, said object and said holding means being rotatable about the vertical axis of said object 180*. .
Claim 2
Independent Claim
131 words
A device for inverting a generally planar object which comprises a means for holding said object on its upper plane and its lower plane, a gear motor with a reversible phase for tilting and re-tilting said object about a fixed axis so that said planes are generally vertical when said object is tilted, said motor having an external shaft on which is affixed a sprocketed wheel, a chain affixed at one end to an upper portion of a turntable over which said means for holding said object rotates, said chain affixed at its opposite end to a lower portion of said turntable, said chain being engaged on the sprocket teeth of said sprocketed wheel, said object and said holding means being rotatable about the vertical axis of said object 180*. .
Claim 3
Dependent Claim
48 words
A device according to claim 1 wherein said holding means is affixed to a turntable which is rigidly but horizontally rotatable mounted to a pair of vertically rotatable semi-circular turntable supporting members maintained generally about the same horizontal axis about which said object and said holding means rotate.
Claim 4
Dependent Claim
31 words
A device according to claim 2 comprising a disengaging means maintaining said turntable rigidly to said semi-circular turntable supporting members when engaged but permitting horizontal rotation with respect thereto when disengaged.
Claim 5
Dependent Claim
24 words
A device according to claim 3 wherein said disengaging means comprise at least one pin insertable within a hole on a vertically rotatable member.
Claim 6
Dependent Claim
69 words
A device according to claim 4 wherein at least one of said semi-circular turntable supporting members is provided with an externally disposed stop member adaptable to engage a brace when said turntable is horizontal and at least one of said semi-circular turntable supporting members has a recess therein which engages a limit switch when said turntable is horizontal whereby the tilting operation is stopped by de-energizing said gear motor.
Claim 7
Dependent Claim
20 words
A device according to claim 4 wherein said turntable is rotatable about a pivot pin functioning as the vertical axis.
Claim 8
Dependent Claim
134 words
A device according to claim 4 embodying a device for engaging the lower and upper plane of the object to be inverted said device comprising a pair of vertical columns each having a pair of forked arms facing one another, one at the top of said column and the other at the bottom of said column, said forked arms rideable on said column, each forked arm on a single column attached to an endless belt mountEd about a pair of opposed rollers, one of said arms connected to one side of said belt and the other connected to the other side of said belt, at least one set of similarly positioned rollers for each column being joined by a common axis movable by a third belt affixed to and movable by a crank arm.
Claim 9
Dependent Claim
26 words
A device according to claim 7 wherein said rollers are sprocketed wheels and said belts are chains which are engaged by the teeth of said wheels.
Claim 10
Dependent Claim
138 words
In a device for inverting a generally rectangular object having an upper plane and a lower plane, a device for engaging the lower and upper planes of the object to be inverted, means for inverting said object, said device comprising a pair of vertical columns each having a pair of forked arms facing one another, one at the top of said column and the other at the bottom of said column, said forked arms rideable on said column, each forked arm on a single column attached to an endless belt mounted about a pair of opposed rollers, one of said arms connected to one side of said belt, at least one set of similarly positioned rollers for each column being joined by a common axis movable by a third belt affixed to and movable by a crank arm.
Claim 11
Dependent Claim
138 words
In a device for inverting a generally rectangular object having an upper plane and a lower plane, a device for engaging the lower and upper planes of the object to be inverted, means for inverting said object, said device comprising a pair of vertical columns each having a pair of forked arms facing one another, one at the top of said column and the other at the bottom of said column, said forked arms rideable on said column, each forked arm on a single column attached to an endless belt mounted about a pair of opposed rollers, one of said arms connected to one side of said belt, at least one set of similarly positioned rollers for each column being joined by a common axis movable by a third belt affixed to and movable by a crank arm.
Claim 12
Dependent Claim
26 words
A device according to claim 9 wherein said rollers are sprocketed wheels and said belts are chains which are engaged by the teeth of said wheels.
Claim 13
Independent Claim
104 words
A device for inverting a generally planar object which comprises a means for holding said object on its upper plane and its lower plane, means for tilting said object about a fixed axis so that said planes are generally vertical, said object and said holding means being rotatable about the vertical axis of said object 180*, said vertical axis and said fixed axis being in the same plane, means for re-tilting said object so that said object returns inverted to its original position and support means generally parallel to the vertical axis of rotation to provide support during rotation of said holding means 180*.
Claim 14
Independent Claim
104 words
A device for inverting a generally planar object which comprises a means for holding said object on its upper plane and its lower plane, means for tilting said object about a fixed axis so that said planes are generally vertical, said object and said holding means being rotatable about the vertical axis of said object 180*, said vertical axis and said fixed axis being in the same plane, means for re-tilting said object so that said object returns inverted to its original position and support means generally parallel to the vertical axis of rotation to provide support during rotation of said holding means 180*.
