Title: Microballistic printer

Abstract: My invention comprises a ballistic impact printer which includes a gun for successively propelling balls along predetermined paths to trace a desired character on a medium supported on a platen spaced from the gun. Means are provided for orienting the gun after each ball leaves the muzzle of the gun so that the desired pattern is formed. Gas under pressure propels a ball along the bore of the gun, which is slightly larger than the diameter of the ball. This enables me to make the gun out of resilient material, since a gas bearing is formed which prevents a ball from touching the sides of the bore while it is traveling down the bore. The breech of the gun is slightly smaller than the diameter of a ball, so that a ball acts as a seal for a chamber in which gas pressure is being built up. When a ball in the breech is dislodged by a succeeding ball, gas from the chamber performs its propelling action between the time the ball is dislodged from the breech and the succeeding ball is seated in the breech. Balls rebounding from the platen are continuously recycled.
