Abstract

A drive system for a regulating the rotation of a drive system or agitator in a paintball loader is disclosed. It is designed to regulate the rotation of a feeder, especially during a jam or when projectiles in a hopper become misaligned. This allows a user to quickly and effectively clear a jam and resume or continue rapid fire without damaging projectiles, the loader or the paintball marker.

Claims (21)

1. A drive mechanism for a projectile loader comprising:
a drive shaft, rotatable about a central axis, having first and second ends and having at least one magnetic portion adjacent the second end;
a feed mechanism rotatable about the central axis and including at least one magnetic or magnetically attractable portion positioned to come into proximity with the at least one magnetic portion so that the feed mechanism is releasably magnetically coupled for movement with the drive shaft.
2. The drive mechanism of claim 1, further comprising a motor coupled to the first end of the drive shaft.
3. The drive mechanism of claim 2, further comprising a controller in operative communication with the motor.
4. The drive mechanism of claim 3, further comprising a sensor in operative communication with the controller.
5. The drive mechanism of claim 3, wherein the rotation of the drive shaft is reversible.
6. The drive mechanism of claim 1, wherein the drive shaft remains rotatable if the feed mechanism is prevented from rotating.
7. The drive mechanism of claim 1, wherein the feed mechanism comprises a base portion which includes the at least one magnetic or magnetically attractable portion.
8. The drive mechanism of claim 1, wherein the feed mechanism further comprises:
an impeller portion and a drive spring having a first end and a second end, the first end of the drive spring coupled to the impeller portion;

and a base portion having a magnetic or magnetically attractable portion and is coupled to the second end of the drive spring, the base portion being operable to wind the drive spring.
9. The drive mechanism of claim 1, wherein magnetic attractive forces between the at least one magnetic portion of the drive shaft and the at least one magnetic or magnetically attractable portion of the feed mechanism is less than a rupture force of a paintball adapted to be loaded by the feed mechanism.
10. A drive mechanism for a projectile loader comprising:
a drive shaft rotatable about a central axis having a keyed portion;
a clutch plate, having a mating keyed opening mounted on the drive shaft, the clutch plate including at least one first magnetic element, the keyed opening matingly engaged with the keyed portion of the drive shaft; and, a feed mechanism rotatable about the central axis adjacent to the clutch plate, the feed mechanism including at least one second magnetic element magnetically attractable to the first binding element.
11. The drive mechanism of claim 10, further comprising a motor coupled to the drive shaft.
12. The drive mechanism of claim 10, wherein the drive shaft remains rotatable if the feed mechanism is prevented from rotating.
13. The drive mechanism of claim 11, further comprising a controller in operative communication with the motor.
14. The drive mechanism of claim 13, further comprising a sensor in operative communication with the controller.
15. The drive mechanism of claim 14, wherein the rotation of the drive shaft is reversible.
16. The drive mechanism of claim 10, wherein the feed mechanism comprises a base portion which includes the at least one second magnetic element.
17. The drive mechanism of claim 10, wherein the feed mechanism further comprises:
an impeller portion and a drive spring having a first end and a second end, the first end of the drive spring coupled to the impeller portion;

and a base portion which includes the at least one second magnetic element and is coupled to the second end of the drive spring, the base portion being operable to wind the drive spring.
18. A method for driving projectiles in a projectile loader comprising the steps of:
a) providing a drive mechanism including:
i) a drive shaft rotatable about a central axis having at least one first magnetic element;
ii) a feed mechanism mounted for rotation about central axis and having at least one second magnetic element magnetically attractable to the first binding element; and b) rotating the drive shaft;

c) rotating the feed mechanism via magnetic force between the at least one first magnetic element and at least one second magnetic element.
19. The method of claim 18, wherein, the at least one first magnetic element and the at least one second magnetic element form a magnetic coupling between the drive shaft and the feed mechanism.
20. The method of claim 18, wherein the magnetic coupling causes the feed mechanism to rotate in unison with the drive shaft.
21. The method of claim 18, wherein the magnetic coupling disengages if the feed mechanism is unable to rotate.
