Abstract:     A launcher for holding and successively launching a plurality of projectiles, such as fireworks projectiles, which explode into an aerial pyrotechnic display. The launcher includes a pressure tank containing a compressed gas and a plurality of launching tubes for holding the projectiles. The launching tubes are constructed to form a magazine to enable successive launching of fireworks projectiles by appropriate indexing of the magazine and thus the launching tubes. A control apparatus opens and closes a valve to introduce compressed gas into one of the launching tubes to launch a projectile into the air. Indexing of the launching tubes when the pressure tank is pressurized prior to launch is prevented by a stop mechanism. The stop mechanism also prevents inadvertent or accidental detonation of the projectile in the launching tube. The launcher further includes an aiming apparatus comprising actuators that support the launcher and which are adjustable to change the launching angle of the launcher with respect to the ground each time a new launching tube is indexed to a launching position. The adjustment of these actuators is controlled by pneumatic switches that are operated during indexing of the launching tubes.

First Claim:

We claim:     1. A launcher for holding and successively launching a plurality of projectiles for exploding into an aerial pyrotechnic display, comprising:
  • (a) a pressure tank containing a compressed gas;
  • (b) a plurality of launching tubes for holding the projectiles;
  • (c) a valve connected to the pressure tank and having an output port registered with a selected one of the tubes;
  • (d) a control apparatus for opening and closing the valve to accurately control the introduction of compressed gas from the pressure tank into the selected one of the tubes to launch a projectile into the air;
  • (e) a stop mechanism for preventing indexing of the tubes when the pressure tank is pressurized and for allowing indexing of the tubes when the pressure tank is depressurized; and
  • (f) an indexing mechanism for selectively indexing another of the tubes into registration with the output port of the valve when the pressure tank is depressurized.
