CPC F41B 11/648 (2013.01) [F41B 11/55 (2013.01); F41B 11/73 (2013.01)] | 15 Claims |
1. An airgun comprising:
a compression tube including a transfer port;
a bolt including a leader portion sized to pass into a projectile supply passageway of a projectile supply;
a bolt positioner that moves with the bolt;
a breech configured to hold the projectile supply such that the projectile supply passageway is substantially in line with a bore of a barrel, wherein the breech includes a bolt guide that is configured to position the bolt between the compression tube and the breech for movement along a path that is substantially co-axial with the projectile supply passageway and the bore;
a bolt positioner guide positioned to interact with the bolt positioner to advance the bolt between (i) a first position extending through the projectile supply passageway and (ii) a second position retracted from the projectile supply passageway;
a first pivot coupling the breech to the compression tube, the first pivot configured for movement between (i) a firing position and (ii) a reloading position;
a cam surface configured to move with the compression tube when the compression tube is rotated relative to the breech; and
a gas flow path disposed between (i) the transfer port and (ii) a firing location in the bore,
wherein the cam surface and the bolt positioner are configured such that rotation of the breech from the firing position to the reloading position causes the cam surface to drive the bolt positioner, against a biasing member, from the first position to the second position to open the projectile supply passageway, and
wherein the cam surface and the bolt positioner are configured such that rotation of the breech from the firing position to the reloading position causes the cam surface to drive the bolt positioner through the projectile supply passageway to drive a projectile in the projectile supply passageway to a position where a release of pressurized gas in the firing location is configured to thrust the projectile through the bore.
