  • Patent number: 9513081
    Abstract: A paintball ejecting apparatus includes a current control mechanism to control current flow to a motor, the current control mechanism including a switch activator having at least a first state and a second state. The switch activator in the first state is physically forced by a paintball to occupy a first position to cause the switch to not permit a current to flow to the motor when the switch activator is in the first state. The switch activator in the second state is not physically forced by any paintball, thereby occupying a second position that results in the switch permitting current to flow to the motor when the switch activator is in the second state.
    Type: Grant

  • Patent number: 8381710
    Abstract: Paintball ejecting apparatus having a body, a breech, and a barrel for ejecting paintballs through and out of the barrel is disclosed. There are included a paintball reservoir disposed in an other-than-top-of-body position and a paintball conduit coupling the paintball reservoir to the breech for facilitating transport of paintballs from the paintball reservoir to the breech. There is also included a paintball transport arrangement having an actuator to move paintballs toward the breech, the paintball transport arrangement automatically moves at least a first paintball from the paintball conduit into the breech if the breech is empty and open for receiving the at least first paintball, the paintball transport arrangement automatically ceasing moving another paintball into the breech after the at least first paintball is disposed in the breech.
