- a barrel, said barrel disposed at a distal end of said chamber;
- said compressed gas source comprising a spring-activated compressed gas chamber comprising:
- a cylinder, said cylinder having a front end and a rear end and being fluidly connected to said chamber at said front end;
- a piston, said piston fitting sealably in said cylinder and being disposed therein;
- a compression spring, said compression spring urging said piston toward said front end;
- a spring compression mechanism, said compression mechanism urging said piston towards said rear end and compressing said compression spring;
- a latching mechanism, said latching mechanism releasably retaining said piston adjacent said rear end and retaining said compression spring in a compressed state;
- and
- wherein when a user operates a cocking mechanism, said spring compression mechanism is operated, said piston is urged toward said rear end of said cylinder, said spring is compressed and said spring and said piston are retained by said latching mechanism until released allowing said piston to move rapidly toward said front end of said cylinder, providing a burst of compressed gas in said cylinder and to said connected chamber;
- said spring compression mechanism comprising:
- a primary gear rack, said gear rack being slidably disposed in a channel in a stock, having gear teeth disposed upon an upper surface and having mounting fixtures adjacent a forward end for attachment of a slide handle;
- a reduction gear drive, said gear drive mounted to an outer cover of said cylinder;
- a secondary gear rack, said secondary rack attached indirectly to said piston and being disposed slidably in a slot in said outer cover above said reduction gear drive;
- said primary gear rack engaging said reduction gear drive and said reduction gear drive engaging said secondary gear rack;
- wherein rearward movement of said slide handle moves said primary gear rack rearward, rotates said reduction gear drive, moves said secondary gear rack rearward and moves said piston rearward, compressing said compression spring;
- a compressed gas release mechanism, said release mechanism connected to said compressed gas source;
- a projectile storage magazine, said magazine storing particulate projectiles and being disposed adjacent said chamber;
- said projectile storage magazine comprising a conical container, said container having a circular opening at a lower end;
- said lower end fitted sealably to an upper end of a vertical circular opening through said chamber;
- said container having a sealing lid removably or hingedly attached at an upper end;
- a projectile loading mechanism, said loading mechanism moving said particulate projectiles into said chamber from said magazine;
- said projectile loading mechanism comprising a metering rod, said metering rod being sized and shaped to fit sealably through said vertical circular opening through said chamber and having an orthogonal activation bar extending from a lower end thereof and a through hole disposed above said activation bar, said through hole being orthogonal to said bar and said metering rod and sized and disposed to align with said chamber when said bar is positioned against a stopping surface;
- said activation bar being urged upwardly by a return compression spring to rest against said lower end of said vertical circular opening in said chamber;
- said through hole filling with said particulate projectiles when disposed above said chamber in said conical container during operation of said cocking mechanism;
- said activation bar being urged downwardly by a pivotally mounted subordination pole to rest against said stopping surface just after activation of said compressed gas release mechanism, permitting said 36 compressed gas to eject said particulate projectiles from said chamber and through said barrel;
- said projectile loading mechanism further comprises:
- a mid-chamber pipe, said pipe extending downwardly from a lower end of said magazine;
- a lower portion of said pipe providing a stop for one end of a return compression spring;
- a trajectory guide, said guide disposed below said magazine, having a hollow bore sized to fit slidably about said pipe and having a vertical slot extending downwardly from said lower end for a first predetermined distance and terminating in a stopping surface;
- said trajectory guide being disposed about said pipe and providing a support platform for attachment of said projectile storage magazine;
- a metering rod, said rod being cylindrical in shape and being sized to fit slidably within said pipe and having an orthogonal activation bar extending from a lower end thereof and a through hole disposed above said activation bar, said through hole being orthogonal to said bar and said metering rod and sized and disposed to align with said chamber when said bar is positioned against said stopping surface;
- said return compression spring urging said metering rod upwardly to rest against said lower end of said vertical circular opening in said chamber;
- and
- said subordination pole having a first end and a second end, being pivotally mounted to said cover for said compressed gas source, said first end comprising a metering slot, said metering slot surrounding said activation bar, said second end being urged upwardly by a cam upon activation of said gas release mechanism;
- wherein upward movement of said second end of said subordination pole moves said activation bar downwardly, compressing said return compression spring and aligning said through hole of said metering rod with said projectile chamber, permitting said compressed gas to drive said particulate projectiles out of said chamber and through said barrel;
- wherein downward movement of said second end of said subordination pole causes said activation bar to move upwardly as urged by said return compression spring, said particulate projectiles filling said through hole of said metering rod as said metering rod moves in said projectile storage magazine surrounded by said particulate projectiles;
- a downward pointing cam lobe on said first end for subordination pole, said cam lobe disposed beneath and orthogonal to said metering slot;
- a cam activating tab, said tab disposed on a side and adjacent front end of an upper surface of said primary gear rack, said activating tab having a contoured inner surface;
- said contoured inner surface being sized, shaped and disposed to engage a front edge of said cam lobe as said primary gear rack is moved rearwardly and forwardly during operation of said cocking mechanism;
- engagement of said cam lobe causing upward movement of said metering rod followed by downward movement of said metering rod during operation of said cocking mechanism, such movement serving to dislodge any particulate projectiles adhering to said metering rod;
- said cocking mechanism mechanically connecting said compressed gas source, said compressed gas release mechanism, and said projectile loading mechanism;
- a primary automatic safety mechanism, said primary safety mechanism moving to an activated position upon utilization of said cocking mechanism and moving to a deactivated position when manually deactivated by a user, status of said primary safety mechanism being displayed by movement of a primary external safety lever from a first, safe position to a second, firing position;
- said stock housing and supporting said compressed gas source, said compressed gas release mechanism, said barrel, said chamber, said projectile storage magazine, said cocking mechanism and said projectile loading mechanism;
- wherein, when said gun is cocked by said cocking mechanism, said projectile loading mechanism gathers a predetermined quantity of said particulate projectiles and positions said projectiles in said chamber;
- and when said compressed gas release mechanism is activated said projectiles are ejected from said chamber into said barrel and expelled from said gun.
