Abstract

An airgun for use with a projectile supply is described. A cam surface of the airgun and a bolt positioner of the airgun are configured so that rotation from a firing position to a reloading position causes a cam surface of the airgun to drive the bolt positioner through a passageway of the projectile supply to drive a projectile in the passageway to a position where pressurized gas in the firing location will thrust the projectile through the bore.

First claim

What is claimed is:

1. An airgun for use with a projectile supply having a housing and a passageway extending along a supply axis into which the projectile supply positions a projectile when the passageway is open, the airgun comprising:
a compression tube having a transfer port from which the compressed air passes during firing of a compression piston;
a bolt with a leader portion sized to pass into the projectile supply passageway;
a bolt positioner that moves with the bolt;
a breech having a projectile supply holder adapted to hold the projectile supply with the projectile supply passageway substantially in line with a bore of a barrel and providing a bolt guide positioning the bolt between the compression tube and the projectile supply holder for movement along a path that is generally co-axial with the passageway and the bore;
a bolt positioner guide positioned to interact with the bolt positioner to advance the bolt between a first position extending through the passageway and a second position retracted from the passageway;
a pivot joining the breech to the compression tube for movement between a firing position where the transfer port, the passageway and the bore are substantially aligned and a reloading position;
a cam surface that moves with the compression tube when the compression tube is rotated relative to the breech;
a gas flow path between the transfer port and a firing location in the bore;
wherein the cam surface and the bolt positioner are configured so that rotation from the firing position to the reloading position causes the cam surface to drive the bolt positioner against a bias from the first position to the second position to open the passageway; and
wherein the cam surface and the bolt positioner are configured so that rotation from the firing position to the reloading position causes the cam surface to drive the bolt positioner through the passageway to drive a projectile in the passageway to a position where pressurized gas in the firing location will thrust the projectile through the bore.

2. An airgun for use with a projectile magazine having a plurality of projectile holders, the airgun comprising:
a compression tube with separated forks, a pivot extending across the forks and a tube fork cam surface;
a magazine positioner adapted to hold the a magazine such that a magazine projectile holder is positioned in a loading area between a tube fork side of the magazine positioner and a bore side of the magazine positioner;
a breech pivotally mounted to the forks for movement at least between a closed orientation with the compression tube proximate the breech and an open orientation, with the breech having a barrel holder positioning a barrel opening on a barrel side of the magazine positioner and having a bolt guide on a bolt guide side of the magazine holder;
a bolt shaped to interact with the bolt guide so that a contact surface of the bolt can be urged between a loading position on the bolt side of the magazine holder and a firing position on the barrel side of the magazine holder and with the bolt having a bolt positioner, a position of which determines a position of the contact surface;
a biasing member urging a drive surface against the tube fork cam surface;
wherein the tube fork cam surface is shaped to interact with a drive bolt positioner to move the bolt so that when the compression tube and the breech are rotated from a closed position to an open position, the contact surface is moved from the firing position through the magazine holder to the loading position, and wherein the tube fork cam surface is further shaped to interact with the bolt positioner to move the bolt so that when the compression tube and the breech are rotated from the open position to the closed position, the contact surface is moved from the loading position through a projectile holder of a magazine in the magazine holder to drive a projectile in the projectile holder to a position where compressed gas from a transfer tube can travel through a gas management system to thrust the projectile through the bore.
