Multiple soft projectile blow gun

A blow gun assembly for rapid continuous-firing multiple soft cylindrical projectiles using a single breath, said assembly comprising:

• a plurality of substantilly cylindrical soft projectiles, each said projectile having a diameter (Dp) and a height (H) and corner radii (R), each said projectile having a central axis centered along said projectile diameter (Dp),
• a mouthpiece configured to transmit a charge of air in a longitudinally forward direction, said mouthpiece including, a proximal end and a distal end, said proximal end including an enlarged tip,
• a breech, said breech defining a cylindrical internal breech chamber having a circular inner diameter (Db) and a proximal end and a distal end, the distance between said proximal end of said breech chamber and said distal end of said breech chamber being greater than said projectile diameter (Dp) but less than three times said projectile diameter (Dp), said proximal end of said breech adjoining said distal end of said mouthpiece in open fluid communication, said breech chamber having a central axis centered along said breech chamber inner diameter (Db), said breech including a projectile entrance port adjacent to said proximal end, said projectile entrance port having a diameter substantially equal to said breech chamber inner diameter (Db),
• an air inlet port between said mouthpiece and said proximal end of said breech chamber, said air inlet port having an upstream side and a downstream side, said air inlet port having a diameter which is less than said projectile diameter (Dp), said upstream side of said air inlet port including at least one of a chamfer and an edge break and a rounded edge,
• an elongated band extending longitudinally from said distal end of said breech, said barrel having a bore opening in direct communication with said distal end of said breech chamber, said bore opening being circular and having a diameter (Do) which is less than said inner diameter (Db) of said breech chamber and less than or equal to said projectile diameter (Dp), said bore opening including a frusto-conical transition from said inner diameter (Db) of said breech chamber to said bore opening diameter (Do),
• a tubular magazine for storing said projectiles, said magazine having an internal diameter (Dm), said magazine having a discharge end in communication with said projectile entrance port of said breech chamber, said magazine configured to sequentially feed said projectiles into said breech chamber with said central axis of said projectiles oriented substantially perpendicular to said central axis of said breech chamber, said magazine including a loading end opposite said discharge end, said magazine including a removable cap covering said loading end,
• a handle extending laterally from said barrel, said handle being generally parallel to said magazine, said handle being located on an opposite side of said assembly from said magazine, said barrel comprising a connector tube and a barrel extension, said handle including a coupling, said handle coupling supporting said connector tube and said barrel extension in axially aligned end-to-end fashion, said connector tube and said barrel extension being in close proximity to one another, and
• said diameter (DM) of said magazine being greater than said projectile diameter (Dp) and less than √{square root over ((Dp2+H2))}−2R(√{square root over (2)}−1), and said diameter (Db) of said breech chamber being approximately equal to said magazine internal diameter (Dm).
