A rapid feed paintball loader for use upon a conventional paintball gun. The rapid feed paintball loader includes a container for holding a plurality of paintballs. At a bottom portion of the container is a rotatable drive cone having a plurality of vertical fins. Each fin spirals outwardly from a center axis of the drive cone. In addition, each fin forms a gap with an adjacent fin large enough to accommodate a paintball. At the bottom of the container is an exit tube which exits from the bottom portion of the container and leads to an inlet tube of the paintball gun. A portion of the exit tube is sloped at an angle equivalent to the slope of a top surface of the drive cone. A catch arm is mounted on an interior surface of the container adjacent to the sloped exit portion of the exit tube. The catch arm is mounted at a height which is above the top surface of the fins, and which is approximately equal to the radius of a paintball. During the operation of the paintball loader, a plurality of paintballs are placed in the interior space of the container. The paintballs fall into the gaps of the drive cone. The rotating drive cone pushes the paintballs toward the first opening. The catch arm then forces the paintball located in the gap into the exit tube for delivery to the paintball gun.

A crossbow includes an elongated frame coupled to a riser at a first end thereof and attached to an upper housing at its second end generally above the trigger region. The riser supports a pair of flexible limbs, and a bowstring extends between such limbs. A bowstring retractor is provided within the upper housing and includes a rope spool used to wind a retractor rope for retracting the bowstring. First and second spool gears surround the rope spool for rotation therewith. A spur gear mounted on a drive axle engages one of the spool gears, and a crank can be engaged with the drive axle. A pawl engages the other spool gear to prevent unintentional unwinding of the retractor rope from the rope spool. A pawl release member disengages the pawl from its associated spool gear. Drawing the bowstring beyond its full draw position also disengages the pawl.

A method and apparatus for expelling a projection from an air gun by striking a primer cap filled with a shock-sensitive explosive compound, causing the cap to explode, which in turn rapidly compresses a volume of air located between the projectile and the cap, causing the projectile to exit from the barrel of the air gun at a high rate of speed.

The present invention is directed to a ball feed mechanism for use in a paintball loader. The ball feed mechanism includes a feeder which conveys or impels balls toward a feed neck, and a drive member which is concentric with the impeller. The feeder is coupled to the drive member through a spring. The spring is configured to store potential energy which is used to rotate the feeder and, thus, drive the balls toward the feed neck. An electric motor is used to rotate the drive member to wind the spring. The feed mechanism includes sensors which detect the motion of the feeder and the drive member. A controller determines the spring tension based on the relative motion of the feeder and drive member, and actuates a motor when necessary.

The invention and disclosure is directed to improvements for a pressure gun utilized to propel paint containing balls which will, when they strike, break and apply paint to a target or, as utilized in the sport of Paint or Splat Ball, an opposing player, to identify such person as having been hit and therefore out of the game. The improvements include both a retro-fit and a custom adapted monitor with visual readout for counting the number of balls which have been shot by sensing pressure drop, or through Hall effect sensing, or mechanical switch actuation; the latter two sensing propelling bolt movement. The monitor also includes a visual readout for reverse timing to show the player game time remaining and a tank pressure supply readout which will show the player remaining tank pressure. Through microprocessing of the information of shot count and time remaining or elapsed, a shooting rate is determinable. Both the retro-fit unit and the custom unit supply the same basic information to the microprocessor which then will calculate shot rate.

An adaptive, force-fed paintball loading device capable of delivering paintballs to a paintball marker against the force of gravity is disclosed. The paintball loading device preferably includes a refillable compartment that is generally an oblong elliptical container holding a plurality of paintballs. Paintballs are able to flow through an opening in the lower portion of the compartment and in between two synchronously geared counter-rotating helical augers. The geometry of flutes on the counter-rotating augers causes the paintballs in the lower portion of the container to be engaged between the augers and then pushed along a channel between the augers and out through a feed tube, which is attached to a paintball marker. A DC electric motor is used to drive the augers. A speed reduction unit is employed to reduce the motor shaft speed to a level practicably used by the synchronously geared augers. A feedback control loop and dynamic coupling element are also employed to enhance the response of the loading system to changing rates of fire of the attached paintball marker. Input signals from sensors on the paintball marker and the paintball loading device may also be employed to enhance the responsiveness of the paintball loading device to the demands of the paintball marker.

A paintball gun loader. The loader is used in a closed-bolt paintball gun. The loader provides a paintball contact surface that moves in oscillating fashion in response to movement of the bolt to load individual paintballs into the gun while the gun loading port is open, which occurs as the gun cycles when fired. The loader includes a spring element that limits the force exerted on the paintball being loaded, even in case of a jam when the paintball contact surface is urged toward the paintball. In one embodiment, a pivotally mounted flexible lever arm having a paintball contact surface oscillates through an angular range of motion in response to a cam surface of the bolt engaging a cam follower on the the loader. In such embodiment, the cam follower is urged toward the cam surface of the bolt, which in turn biases the paintball contact surface toward an open, paintball receiving position.

A compressed gas gun which includes a bolt assembly which is easily removed without the necessity of disassembling the gun or special tooling. The bolt is located at the back of the gun barrel and operatively connected to the hammer assembly by a retracting pin member positioned within an aperture formed in the hammer assembly. By depressing a spring tensioned component at the rear of the bolt, the restraining pin member is caused to move along a groove, or channel, formed in a channel member, raising the pin member from the aperture in the hammer assembly from the gun and allowing the bolt assembly to be removed from the gun. The bolt assembly is reinstalled by reversing the above process.
