Abstract

The invention relates to a machine allowing the repetitive firing of firework bombs by exploding a mixture of gases. A fast loading system places a bomb in a gun from which, after closing the breech, it is ejected and ignited by exploding a mixture of explosive gases, the breech reopens and the cycle can be repeated rapidly. The machine according to the invention is intended for firing fireworks.

Description

La presente invention concerne une machine permettant de tirer à répétition, par l'explosion d'un mélange de gaz, des bombes d'artifice. The present invention relates to a machine for repeatedly firing, by the explosion of a mixture of gases, fireworks bombs.

Dans les feux d'artifice ou autres spectacles pyrotechniques, le tir des bombes d'artifice ou marrons d'air est traditionnellement effectué dans des tubes de diverses matières appelés mortiers.In fireworks or other pyrotechnic shows, the firing of fireworks or air chestnuts is traditionally carried out in tubes of various materials called mortars.

Ces mortiers sont chargés chacun d'une bombe et d'une petite charge de poudre servant de propulseur. Celle-ci est mise à feu par une mèche qui peut elle même être allumée par un dispositif électrique. La flamme de cette première explosion propulsive enflamme la mèche de la bombe, qui eclatera en l'air. On en est,en quelque sorte,à l'âge du canon Gribeauval.These mortars are each loaded with a bomb and a small charge of powder used as a propellant. This is ignited by a wick which can itself be lit by an electrical device. The flame of this first propellant explosion ignites the wick of the bomb, which will explode in the air. We are, in a way, at the age of the Gribeauval canon.

La machine selon l'invention permet à un seul tube de tirer à répétition, selon un rythme programmable,un un grand nombre de bombes avec une grande précision en portée et direction, ce qui crée l'effet d'une cascade de feu.The machine according to the invention allows a single tube to fire repeatedly, according to a programmable rhythm, a large number of bombs with great precision in range and direction, which creates the effect of a cascade of fire.

Elle est constituée d'une chambre munie d'arrivées de gaz, contrôlées par des électrovannes, et d'un dispositif d'allumage du mange de gaz qui peut être constitué de bougies haute tension, similaires à celles qui servent à allumer les chaudières.It consists of a chamber fitted with gas inlets, controlled by solenoid valves, and a device for igniting the gas eater, which may consist of high-voltage spark plugs, similar to those used to light boilers.

Cette chambre est prolongée d'un canon d'un calibre, augmenté d'un vent considérable, correspondant a celui des bombes qu'on se propose de tirer.This chamber is extended by a caliber cannon, augmented by a considerable wind, corresponding to that of the bombs which it is proposed to shoot.

I1 est muni d'une ouverture permettant le chargement de celles-ci lorsqu'une culasse tubulaire,que des vérins pneumatiques font coulisser sur le canon, ne vient pas l'obturer.  I1 is provided with an opening allowing the loading of these when a tubular breech, that pneumatic cylinders make slide on the barrel, does not come to close it.

les bombes d'artifice,sans leur propulseur, sont placées dans un chargeur qui peut être une gouttière en forme de U dans laquelle les bombes sont poussées une par une dans l'ouverture du canon par un doigt animé par des petits vérins pneumatiques.En position de repos, la culasse est ouverte et une bombe C poussée a l'intérieur de la chambre.the fireworks bombs, without their propellant, are placed in a charger which can be a U-shaped gutter in which the bombs are pushed one by one into the opening of the barrel by a finger animated by small pneumatic cylinders. rest position, the breech is open and a C-bomb pushed inside the chamber.

Au déclenchement du cycle, la culasse, actionnée par ses vérins, se ferme et des électrovannes libèrent dans le tonnerre un mélange explosif composé d'oxygène et d'un combustible, qui peut être de l'acétylène par exemple.At the start of the cycle, the cylinder head, actuated by its cylinders, closes and solenoid valves release in the thunder an explosive mixture composed of oxygen and a fuel, which can be acetylene for example.

Ce mélange aéton gr ^Ful'étincelle d'une bougie.This aeton mixture gr ^ Ful the spark of a candle.

La bombe est chassée par l'explosion, la culasse se rouvre, une nouvelle bombe est introduite dans la chambre, et le cycle est pret à recannencer
Le fonctionnement cyclique peut être contrlé par un ensemble de relais temporisés permettant de programmer les pcsitions de la culasse, du doigt de chargement, le temps d'injection du mélange explosif, du retard à l'allumage et du temps de rechargement, ou par un ordinateur permettant d'intégrer ces tirs dans la régie générale d'un spectacle.The bomb is driven off by the explosion, the breech reopens, a new bomb is introduced into the chamber, and the cycle is ready to start again
The cyclic operation can be controlled by a set of time relays allowing programming of the parts of the cylinder head, of the loading finger, the time of injection of the explosive mixture, the ignition delay and the recharging time, or by a computer allowing these shots to be integrated into the general management of a show.

La machine selon l'invention est destinée au tir de feux d'artifice. The machine according to the invention is intended for firing fireworks.
