Abstract:     A target shooting apparatus having a shooting station and a target station separated by a range area with a projectile launcher at the shooting station adapted to discharge frozen particles in a controlled trajectory at the target station. The projectile launcher is provided with a frozen projectile supply having a refrigeration plant for the freezing of an aqueous medium into a plurality of frozen projectiles and transport facilities are provided for delivering the frozen projectiles to the shooting station. In a typical embodiment, the refrigeration plant is a conventional ice cube maker with a suitable dispenser and pnuematic transport facilities for dispensing and delivering ice cubes to the breech of a simulated artillery piece such as a cannon for launching at a target such as a ship in an aquatic environment. The artillery piece has an outer housing which simulates the barrel of a cannon with an internal, resonator sleeve supported at its discharge end in which the barrel of the frozen projectile launcher is supported. The launcher is powered with a compressed gas and the resonator sleeve acoustically amplifies the release of air pressure from the barrel. The launcher is also provided with a breech body having a central, transverse bore in which is rotatably mounted a plug member. The plug member has a projectile chamber which, when the plug is rotated between loading and firing positions, assumes a generally coaxial extension with radial bores in the breech body.

First Claim:
Show all 10 claims
I claim:     1. A target shooting apparatus comprising:
  • a shooting station;
  • a target station positioned down range therefrom and having target means within the range of projectiles launched from said shooting station;
  • a frozen projectile supply means remote from said shooting station having refrigeration means for the freezing of an aqueous medium into a plurality of solid-form frozen projectiles;
  • frozen projectiles storage means communicating with said frozen projectile supply means for storing frozen projectiles supplied thereby;
  • frozen projectile transport means for delivering frozen projectiles singly to said shooting station;
  • dispensing means to discharge said frozen projectiles, singly, into said transport means from said storage means;
  • cold chest means surrounding said storage means and said dispensing means; and
  • projectile launching means at said shooting station including means communicating with said transport means to receive said frozen projectiles singly from said transport means and to place each of said projectiles into a location in said launching means from which it is to be launched, said projectile launching means further including means to direct said launching means towards said target means and to discharge said projectiles from said launching means in a controlled trajectory at said target means.
