Abstract: A toy air gun and in particular an improved air gun for generating vortex rings are described. The gun is designed so that the path along the axis of air motion from the rear of the gun to the air exit hole is optically transparent, and contains patterns normal to this axis that assist in accurate sighting. This allows targets to be directly sighted along the axis of air or vortex ring travel. Together with improvements to ensure purely axial air motion, this dramatically increases the aiming accuracy of this class of gun and makes it suitable for target-type activities. A screen with a cylindrically symmetric pattern of openings and aiming marks prevents solid objects placed inside the gun's barrel from being projected outwards, and assists in aiming the gun. An vented safety guard at the exit end of the gun prevents large pressures from developing in the event that the gun exit is blocked while preserving the vortex ring component to the airflow.

Abstract: A pneumatic device for firing projectiles with a charge of compressed air that accelerates a projectile carrier and the projectile through a barrel. The charge of compressed air is released into the barrel behind the projectile carrier and acts on the projectile carrier to initially accelerate it and a ball or other projectile down the barrel. The diameter of the projectile carrier is slightly less than that of the barrel and it includes a concave recess that receives balls of differing diameters, centering as they are accelerated through the barrel. The barrel is sufficiently long so that the projectile carrier comes to a halt before being ejected from the barrel. An intake for a compressor that develops the charge of compressed air is coupled in fluid communication with the barrel, behind the projectile carrier. Operation of the compressor produces a partial vacuum so that ambient air pressure forces the projectile carrier back to its firing position.

Abstract: A compact pneumatically powered apparatus for automatically propelling game balls, especially tennis balls and the like intended to be stroked by a hand held racket or other implement, for training players in the proper return of the simulated ball action. Each ball is ejected from the apparatus with a combination of forward or straight-line acceleration together with a predetermined amount of ball spin to closely approximate the intentional spin placed on tennis balls when stroked obliquely by a tennis racket. This is achieved in the apparatus by a mechanism for flexing an elongate pliable member, such as a flexible belt, between an initial slackened looped condition and a straightened tensioned condition. The tennis balls are successively fed into a launching position contacting a surface portion of the slackened, looped belt that faces generally forwardly toward the direction of ball propulsion and is initially rearwardly of the final orientation of the tensioned belt.
