Abstract

A ball transfer device is disclosed herein. An embodiment of the ball transfer device includes a chamber, wherein a first opening and a second opening extend into the chamber. A ball is located between the first opening and the second opening and is movable within the chamber. The movement extends between a first position and as second position, wherein a portion of the ball is movable into the first opening when the ball is in the first position.

Claims (40)

1. A ball transfer device comprising:

a chamber;

a first opening extending into said chamber;

a second opening extending into said chamber;

a ball, wherein said ball is movable within said chamber between a first position and a second position, wherein a portion of said ball is movable into said first opening when said ball is in said first position; and

a first bearing located proximate said first opening, wherein said ball is contactable with said first bearing, wherein said first bearing comprises a hole located adjacent said second opening and wherein said ball is receivable in said hole;

wherein said ball is located between said first opening and said second opening.

2. The ball transfer device of claim 1 , wherein said second opening is connectable to a fluid supply.

3. The ball transfer device of claim 2 , wherein said fluid is air.

4. The ball transfer device of claim 1 , wherein a positive fluid pressure is maintainable between said ball and said second opening.

5. The ball transfer device of claim 1 , wherein said ball is movable into said first opening and wherein a greater portion of said ball is located in said first opening when said ball is in said first position than when said ball is in said second position.

6. The ball transfer device of claim 1 , wherein said first bearing comprises wood.

7. The ball transfer device of claim 1 , wherein said first bearing comprises oil impregnated wood.

8. The ball transfer device of claim 1 , wherein said first bearing has a recessed portion connected to said hole, and wherein said recessed portion is configured to receive said ball.

9. The ball transfer device of claim 1 , and further comprising a second bearing located within said chamber, wherein said ball is located between said first bearing and said second bearing.

10. The ball transfer device of claim 9 , wherein said second bearing comprises wood.

11. The ball transfer device of claim 10 , wherein said second bearing comprises oil impregnated wood.

12. The ball transfer device of claim 9 , wherein said second bearing has a hole located therein and wherein said ball is receivable in said hole when said ball is in said second position.

13. The ball transfer device of claim 1 , and further comprising material located proximate said first opening, wherein said material contacts said ball when said ball is in said first position and said second position.

14. The ball transfer device of claim 13 , wherein said material has a hole located therein, said hole being adjacent said first opening and wherein said ball is located within said hole.

15. A ball transfer device comprising:

a chamber;

a first opening into said chamber;

a second opening into said chamber;

a ball located in said chamber and positionable between a first position and a second position, wherein a portion of said ball extends through said first opening when said ball is located in said first position;

a first annular bearing located proximate said first opening, wherein said first annular bearing has a hole extending therethrough and wherein said ball is receivable within said hole;

a second annular bearing having a hole located therein, wherein said ball is moveable between said first annular bearing and said second annular bearing and wherein said ball is receivable within said hole.

16. A conveyor comprising:

a platform comprising at least one hole located therein;

a ball transfer device located in each of said at least one hole, said ball transfer device comprising:

a chamber;

a first opening extending into said chamber;

a second opening extending into said chamber;

a ball, wherein said ball is movable within said chamber between a first position and a second position, wherein a portion of said ball is extendable through said second opening when said ball is in said first position, wherein said ball is located between said first opening and said second opening; and

a second bearing located within said chamber, wherein said ball is located between said first bearing and said second bearing.

17. The conveyor of claim 16 , and further comprising a first bearing located proximate said first opening, wherein said ball is contactable with said first bearing.

18. The conveyor of claim 17 , wherein said first bearing comprises wood.

19. The conveyor of claim 16 , wherein said second bearing comprises wood.

20. The conveyor of claim 16 , and further comprising a wall extending substantially perpendicular to said platform, wherein at least one pulley is located in said wall.

21. The conveyor of claim 20 , wherein said at least one pulley is motorized.
