Abstract
An improved toy air gun is disclosed comprising a generally parabolic barrel having a muzzle opening at the truncated apex of the parabola. A handle and trigger mechanism are attached to the barrel exterior opposite the muzzle. A resilient diaphragm is mounted transversely of the barrel interior. Cocking means for grasping, stretching and locking the diaphragm rearwardly is provided on the gun. The trigger mechanism releases the diaphragm from the locked rearward stretched position to cause a puff of air to issue from the muzzle opening. A screen is mounted within the barrel between the muzzle opening and the diaphragm. An auxiliary cone is circumferentially attached by mounting ribs about the muzzle opening. The anterior end of the auxiliary cone has an opening of a diameter about equal to the muzzle opening. The auxiliary cone provides a circumferential opening around the muzzle having an area about equal to the area of the muzzle opening.
