Automatic feed marking pellet gun

A compressed gas powered gun for discharging projectiles and, upon the discharge of one projectile, to automatically position another projectile in a location within the gun to be subsequently discharged therefrom comprising:

• a compressed gas source;
• a projectile supply magazine containing a plurality of projectiles, each projectile having a generally circular cross-sectional configuration;
• a barrel through which projectiles may be sequentially discharged;
• means including a user actuable trigger, a spring loaded slide which is released to move under spring urging upon user actuation of the trigger, and a valve assembly actuable by slide impact to release compressed gas thereby selectively supplying compressed gas from the source to expel a projectile through the barrel, the slide and valve assembly being axially aligned with the barrel, the valve assembly being movable along the common axis and including one valve near each end thereof, one of said valves opening when impacted by the slide to provide blow-back gas pressure for returning the slide against spring bias to a retracted position preparatory to discharging a subsequent projectile;
• and
• means for sequentially aligning projectiles from the supply magazine with the barrel.

A compressed gas powered marking gun for firing marking pellets each of which is generally spherical and sufficiently fragile so as to break upon impact with a target comprising:

• a compressed gas source;
• a projectile supply magazine containing a plurality of projectiles, the magazine receiving, in a generally spiral pattern, a plurality of projectile containing clips with their respective cylindrical axes parallel, the magazine containing a generally constant force spring for urging projectile containing clips from the magazine;
• a barrel through which projectiles may be sequentially discharged;
• means including a user actuable trigger for selectively supplying compressed gas from the source to expel a projectile through the barrel, and a selector mechanism movable between a first position where the trigger actuated supplying of gas is disabled, a second position where one actuation of the trigger supplies gas to expel a single projectile, and a third position where compressed gas is repeatedly periodically supplied;
• and
• means for sequentially aligning projectiles from the supply magazine with the barrel including at least one projectile containing clip received within the magazine and formed as a rigid open-ended hollow cylinder having an inside diameter substantially the same as the circular cross-section diameter of the projectile, and means actuated by compressed gas as it expels a projectile through the barrel for initiating clip movement to align another projectile with the barrel.

• a clip latch for holding a clip in alignment with the barrel against the urging of the constant force spring, the clip latch releasing in response to gas pressure as a projectile is propelled from its clip and along the barrel to allow the constant force spring to eject the clip and position a next projectile containing clip from the magazine into position in alignment with the barrel, the clip latch comprising a pivotable arm one end of which, when in a first position, engages a clip to hold that clip in alignment with the barrel, the arm pivoting to a second position releasing the clip in response to said gas pressure, the arm having another end which, when the arm is in the second position, lies in the path of ejected clips, so that, when a clip is ejected, the clip strikes the arm returning the arm to the first position.
