- 2. A machine as set forth in claim 1, wherein said rotating means includes reversible means for rotating said first support around its axis, said rotating means rotating said first support in a first direction around its axis in repositioning said second support from facing in an upward direction to said position in which said second support faces in a downward direction and, thereafter, rotating said first support in a second, opposite direction around its axis to a position in which said second support faces in an upward direction.
- 3. A machine as set forth in claim 1, wherein said rotating means sequentially (a) rotates said second support and then stops the rotation thereof, (b) rotates said first support until said second support faces in said downward direction, (c) again rotates said second support and then stops the rotation thereof, (d) rotates said first support until said second support faces in an upward direction, and (e) again rotates said second support and then stops the rotation thereof.
- 4. A machine as set forth in claim 1, wherein said rotating means comprises motor means driving said timing means, said timing means comprising rotatable cam means, second motor means mounted on said first support and connected to said second support for rotating the latter on its axis, and means including switch means between said timing cam means and said second motor means for actuating and deactuating the latter responsive to rotation of said cam means.
- 5. A machine as set forth in claim 1, wherein said rotating means comprises motor means including means connecting said motor means to said first support for imparting selected intermittent rotation to the latter on its said axis, and second motor means mounted on said first support and connected to said second support for rotating the latter on its said axis, and said timing means comprises rotatable cam means and means including switch means actuated upon rotation of said cam means and connected to said second motor means for imparting selected intermittent rotation to said second support.
- 6. A machine for tilting and rotating a container comprising a first support mounted for rotation around a predetermined, horizontal axis, a second support normally in a position in which it faces in an upward direction for receiving said container in the upright position thereof and rotatably mounted on said first support with its axis of rotation extending transversely to said first-mentioned axis, clamping means mounted on said first support in spaced relation to said second support for rotatably securing said container between said clamping means and said second support, motor means including means connecting said motor means to said first and second supports for independently rotating each of them about their respective axes, and timing means connected to said motor means for sequentially (a) causing said motor means to rotate said second support, (b) causing said motor to rotate said first support until said second support faces in a downward direction, (c) causing said motor means to rotate said second support while said second support faces in the downward direction, (d) causing said motor means to rotate said first support to reposition said second support until it faces in an upward direction and (e) causing said motor means to rotate said second support.
- 7. A machine as set forth in claim 6, wherein said timing means first causes said motor means to rotate said first support and thereby move said second support to a predetermined position at an angle less than 90.degree. from said position in which it faces in an upward direction and then causes said motor means to rotate said second support intermittently and a plurality of times while said second support is in said predetermined position.
- 8. A machine as set forth in claim 7, wherein said motor means comprises a first motor connected by said connecting means to said first support for rotating the latter, a second motor mounted on said first support and connected by said connecting means to said second support for rotating the latter and said timing means comprises a third motor, cams driven by said third motor and switches operable by said cams, said switches being connected to said first and second motors and thereby respectively causing rotation of said first and second supports.
- 9. A machine as set forth in claim 8, wherein said first motor comprises a rotatable output shaft, and said connecting means connecting said first motor to said first support comprises a gear rotatable with said first support, a linear rack engaging said gear and means on said shaft spaced from the axis thereof and pivotally connected to said rack for oscillating said rack and causing at least longitudinal movement thereof.
- 10. A machine for tilting, rotating and inverting a container comprising a first support mounted for rotation on a predetermined axis, first motor means connected to said first support for rotating the latter on its said axis, a second support for receiving said container rotatably mounted on said first support with its axis of rotation extending transversely to said first-mentioned axis, second motor means mounted on said first support and connected to said second support for rotating the latter on its said axis, clamping means mounted on said first support in spaced relation to said second support for rotatably securing said container between said clamping means and said second support, and timing means connected to said first and second motor means for sequentially (a) operating said first motor means for the time required to rotate said first support through an angle less than 90.degree., (b) intermittently operating said second motor means a plurality of times to spin said second support a plurality of times, (c) operating said first motor means for the time required to rotate said first support through an angle substantially equal to 180.degree. minus said first-mentioned angle, (d) operating said second motor means for a predetermined time to spin said second support, (c) operating said first motor means for the time required to rotate said first support through an angle substantially equal to 180.degree. and (f) operating said second motor means for a predetermined time to spin said second support.
- 11. A machine as set forth in claim 10, wherein said first motor has a rotatable output shaft and said first motor is connected to said first support by rack and gear means comprising a gear on said first support rotatable therewith, a rack engaging said gear, driving means on said shaft rotatable therewith and means spaced from the axis of said shaft pivotally connecting said driving means to said rack for oscillating said rack and causing at least longitudinal movement thereof.
- 12. A machine as set forth in claim 11, wherein said timing means comprise a third motor, a plurality of cams driven by said third motor and a plurality of switches having actuating means operable by said cams, and further comprising a pair of switches having actuating means, means connecting said pair of switches electrically in series with said first motor and means mounting said pair of switches with the actuating means thereof in the path of movement of said rack and gear means for operating one of said pair of switches in a first predetermined position of said rack and gear means and the other of said pair of switches in a second predetermined position of said rack and gear means.
- 13. A machine as set forth in claim 10, wherein said timing means comprises a third motor, a plurality of cam driven by said third motor and a plurality of switches having actuating operable by said cams, means connecting at least one of said switches electrically in series with said first motor and means connecting at least one of said switches electrically in series with said second motor.
