Abstract: The body 12 of an air gun accommodates a removable magazine 16 immediately behind the breech 14, for pellets to be loaded one at a time from the magazine into the breech. The magazine comprises a drum 33 which is rotatably mounted within a housing 31 and comprises ten pellet-holding slots 38 around its axis. A torsion spring 42 urges rotation of the drum in indexing steps as controlled by an escapement mechanism comprising a rocking pawl 50. The pawl is displaced against the action of a return spring 58 by a plunger 60 which projects from a cocking arm 22 of a conventional cocking mechanism of the gun; the plunger is arranged to actuate the escapement only towards the end of a cocking stroke of the arm 22. A loading ram/air transfer tube 28 is reciprocated, in effecting the cocking action, to withdraw from one slot 38 in the drum and enter a next slot to load a fresh pellet into the breech.

Abstract: An air gun having a fixed barrel mounted on a body and a source of compressed air or gas housed in the body has a device for enabling a pellet to be inserted directly into the barrel. A breech block is angularly movable between a loading position in which the breech is exposed and a firing position in which the breech is closed, the breech block having passage for completing the connection between the breech and the source of compressed air. In the embodiment shown the breech block is cylindrical and is rotatably mounted in a continuation of a cylinder in which a spring urged piston works, and has a guide chute in its cylindrical surface to assist the introduction of the pellet. Seals may be provided at either end of the breech block.
