Cycle Chain of Events
1. Firing of the unit is accomplished by pulling the trigger. However, this assumes that the Selector is in one of the two firing modes (Semi-Automatic or Fully Automatic). Note: Selective functions and positions will be covered in a later section.
2. When the Trigger is pulled, the Pawl is forced upward against the bottom of the Sear. This causes the Sear to rotate, causing a disengagement of the Hammer Assembly from the Bolt.
3. Upon disengagement, the Hammer Assembly is fired rearward where it first comes into contact with the Valve Tube.
4. This releases a rapid pulse of high-pressure gas, thereby ejecting the paintball housed within the Breech Sleeve through the Barrel. Note: After the paintball has left the Barrel, the Striker continues rapidly traveling rearward. The Striker then comes into contact with a protruding cam portion of the Rocker, which urges the Rocker into a rotational motion.
5. This rotational motion is resisted by the Follower. The Follower is an over-center cam acting against a protruding cam on the Rocker by means of a coil Compression Spring.
6. Once the protruding cam on the Rocker rotates past the center peak of the Follower, the Follower forces the Rocker to continue rotating as far as it will go (to a stop point within the Follower cavity).
7. At this point, a cam protrusion on the Rocker will urge forward a flange on the Cycle Spool. When this happens, the Cycle Spool is urged to a new position where it is stopped from further forward motion by the Retainer.
8. The reduced pressure gas that is coming from the low-pressure side of the Regulator Assembly that is contained in the Central Spool Area is redirected to Ports.
9. When gas is redirected into Ports, it is directed into the Annular Port and then through an orifice into Area Cylinder Front. This causes the Piston Assembly to be urged rearward in the Cylinder.
10. The Piston Assembly is attached to the Bolt and is also urged rearward toward the Hammer Assembly, which is at rest upon the Valve Tube. Note: A coil compression spring lies between the Bolt and Hammer Assembly.
11. As the Sear latches over the rear lip of the Bolt, the rearward motion of this entire assembly is suddenly and automatically reversed to forward motion by way of the Timing Collar coming into contact with a cam protrusion on the Rocker.
12. As the Rocker reverses direction and overcomes the center point of the Follower, the Rocker is forced to continue rotation. This causes protruding cams on the Rocker to strike rearward flange on the Cycle Spool causing the Cycle Spool to urge rearward to a stop position within the Rear Housing.
13. At this time, low-pressure gas from the Area is redirected into Ports. This directs low-pressure gas from the Area into the Annular Port Area and through an orifice into the rear portion of the Cylinder Chamber causing the Piston Assembly to be urged and held forward.
Simultaneous Loading
1. As the Piston Assembly was in rearward motion, a simultaneous automatic loading operation was taking place at the forward end of the Piston Assembly. At the forward end of the Piston Assembly is the Coupling.
2. The Coupling is attached by a depressible Coupling Pin to the Cog Assembly. When the Piston Assembly is traveling rearward, the Cog Pull is also pulled rearward along a Guide Way
.
3. At this time, please note the Side Cover Assembly. Also reference the Guide Leaf and Cog Pin. Please note that the Guide Leaf is permanently installed into the Side Cover so that the Side Cover Assembly is made up of parts. Also note the position of the Cog Pin for future reference. Note: the Cog Pin is permanently installed into the Cog.
4. As the Cog Pull is traveling rearward, the protruding pins of the Cog Pull cause the Cog to travel in a downward motion. The Cog is prevented from traveling rearward because of the fact that the permanently attached Cog Pin is resting against the forward face of the Guide Leaf. The downward motion is accomplished by the protruding pins of the Cog Pull interacting with the cam slots of the Cog causing a downward motion of the Cog until it reaches the point at which both the Cog Pin is not restricted by the Guide Leaf and the protruding pins of the Cog Pull reach the end of the cam stroke of the cam slots of the Cog.
5. At this point, the teeth of the Cog engage with links of the Conveyor Chain.
6. The Piston Assembly, Cog Pull and Cog all continue their rearward motion and simultaneously at this time begin transport motion of the Chain.
7. Cantilevered lugs are then mounted onto the Chain at six link intervals. On these cantilevered lugs are permanently mounted soft molded cushions. In between these cushions are paintballs that are contained within an L-shaped track.
8. The upward traveling side of the Chain is on the left.
9. As the Piston Assembly travels further rearward and the Chain is engaged into the Cog, a paintball will travel vertically into the Breech Staging area above the Cassette and behind the Barrel.
10. As the Bolt is traveling rearward, the timing is such that a paintball is able to come to rest in front of the Bolt without coming into hard contact at a high velocity with any hard portions of the Bolt. Note: when the Chain is transporting a paintball vertically into the Breech Staging position, a paintball has to overcome the slight force exerted sideways onto the paintball by the Spring Guide.
11. As the paintball travels above the center line relationship between the paintball and the inward protruding radius of the Spring Guide, the Spring Guide is urged inward by means of its own spring tension. This ensures the center line location of the paintball in the Breech Staging area wherein the paintball has no choice but to rest on the top portion of the relaxed Spring Guide.
12. At this time, the Chain has fully accomplished a transport of distance of exactly six links when the Piston Assembly has reached the end of its rearward stroke.
13. Exact chain indexing location is ensured by means of detents that are located 120 degrees apart on the underside of the Indexer. Also note that proper tension is attained by a Tensioner Assembly.
Note: As a paintball is transported and loaded into the Breech Staging area forward of the Bolt while the Bolt is traveling rearward, the paintball's upward motion is rapidly decelerated gently by means of a resilient cushion Sleeve Pad that is mounted into the upper forward portion of the Sleeve.
14. As the Piston Assembly and Bolt travel forward, loading the paintball into the Breech Staging area, guide slots of the Cog are free to disengage from the protruding pins on the Cog Pull. This leaves the teeth portion of the Cog free to ride out of lugs of the Chain and free to travel further forward.
15. As the entire assembly is traveling forward, the Cog Pin is riding on the upward side of the Guide Leaf.
16. As the Cog Pin reaches the looped end portion of the Guide Leaf, the Guide Leaf deflects downward by force of the Cog Pin until the Cog Pin travels forward to a point allowing the forward portion of the Guide Leaf to spring back upward into a resting position, thus completing one cycle in preparation for firing.
Firing Mode Selection
1. Safe Position
With the Safe Position of the Selector where the Select Lever is horizontally facing the rear, the Safety is forced rearward by means of the Selector not allowing the Forward Nose of the Safety to protrude into exposed Safety Slots in the Selector. Note: Vertical detail on the Pawl is always urged rearward by the Pawl Spring. This causes the rear vertical surface of the Pawl to rest on the protruding face of the Safety so that when the Trigger is pulled, the Pawl is guided behind the Sear. This prevents the Hammer Assembly from being disengaged with the Bolt, thereby disabling the firing mechanism.
2. Semi-Automatic Position
a. With the Semi-Automatic position of the Selector where the Select Lever is diagonally facing downward at a 45 degree angle toward the rear, if the Trigger is pulled, the Pawl is in a position so that it will force the Sear to disengage the Hammer Assembly from the Bolt, thereby firing and cycling the unit.
b. While the Trigger remains to be pulled, the unit has rapidly repeated one cycle and as the Hammer Assembly is traveling forward, the diagonal portion of the lower lobe of the Sear comes into contact with the upper rear radius of the Pawl. This causes the vertical portion of the Pawl to rotate into the clearance cavity Area of the Selector. Note: Because of the fact that the Pawl is only slightly urged rearward by means of the Pawl Spring, it does not cause the disengagement of the Sear from the Bolt. It should be noted that at this point, the Hammer Assembly is prevented by other means from traveling any farther forward than the position as shown.
c. As the user releases pressure on the Trigger, the Pawl is free to rotate and rest against the Safety where it is ready, once again, to apply upward force to the Sear, upon subsequent pulls of the Trigger.
3. Fully Automatic Position
a. With the Fully Automatic Position of the Selector where the Select Lever is at an upward diagonal angle of 45 degrees to the rear, and as the Trigger remains to be pulled and the Hammer Assembly and the Bolt are traveling forward, the forward diagonal portion of the lower lobe of the Sear will come into contact with the upper rear radius of the Pawl. This will cause the Pawl to rotate forward, coming into contact with the Face of the Selector.
b. As the Hammer Assembly and Bolt continue traveling forward, the lower lobe of the Sear is forced to rotate and disengage the Hammer from the Bolt. At the time, while the Hammer Assembly and Bolt are still traveling in a forward motion, but nearing the end of the cycle stroke, this causes subsequent automatic disengagement of the Sear from the Bolt, while the Trigger remains to be pulled.
c. Automatic disengagement as described above will cease and reset to a "ready to fire" position the moment the Trigger is released. The Pawl is in the "ready to fire" position and will disengage the Sear from the Bolt when the Trigger is pulled once more, causing a complete cycle.
