Abstract

The humane killer comprises a cylindrical body (1) containing a piston (5) attached to a rod (6). When the trigger (16) is pulled, compressed air is admitted behind (10) the piston but no movement occurs as it is held by pawls (17). The gun is placed against the animal's head and pushed down. A collar (35) moves rearwards and an external rod (40) actuates a microvalve (27). This admits air to a second piston (23), immediately behind the first. This second piston moves forward, its walls (28) releasing the pawls and the main piston rapidly advances to meet the bolt (29) and drive it home.
