Description

La présente invention concerne les dispositifs ou systèmes d'alimentation considérés, au sens général, pour assurer le fonctionnement d'appareils de tir à gaz comprimé en mode semi-automatique de projectiles divers.The present invention relates to the supply devices or systems considered, in the general sense, to ensure the operation of compressed gas shooting devices in semi-automatic mode of various projectiles.

La présente invention concerne, indifféremment, les appareils de tir de clous ou analogues, tels que les pistolets cloueurs ou agrafeurs ou, encore, les armes, telles que celles tirant des projectiles à base de matières malléables comme le plomb, pour l'entraînement au tir ou la pratique de sports.The present invention relates, indifferently, to devices for firing nails or the like, such as nail guns or staplers or, again, weapons, such as those firing projectiles based on malleable materials such as lead, for training in shooting or playing sports.

Dans le domaine technique ci-dessus, il existe des systèmes d'alimentation généralement conçus en fonction du caractère spécifique du projectile. Ces dispositifs font intervenir, plus spécialement, soit une alimentation par gravité, soit une alimentation à partir d'une bande ou d'une collection de projectiles reliés entre eux, afin de posséder une cohérence ou une tenue mécanique nécessaire pour leur déplacement dans un couloir de guidage.In the above technical field, there are supply systems generally designed according to the specific nature of the projectile. These devices involve, more specifically, either a gravity feed, or a feed from a strip or a collection of projectiles linked together, in order to have the consistency or mechanical strength necessary for their movement in a corridor. guide.

Ces deux systèmes ne donnent pas satisfaction car le premier est essentiellement réservé aux projectiles de type sphérique, alors que le second implique, obligatoirement, un précondi- tionnement des projectiles devant être tirés.These two systems are not satisfactory since the first is essentially reserved for spherical type projectiles, while the second necessarily involves preconditioning the projectiles to be fired.

Il existe, également, des systèmes d'alimentation qui sont plus spécifiquement réservés à des appareils particuliers en constituant pour ces derniers des réserves en forme de barillets.There are also supply systems which are more specifically reserved for particular apparatuses by constituting barrel-shaped reserves for the latter.

De tels systèmes ne sont pas entièrement satisfaisants non plus, car l'inconvénient principal d'une réserve à barillet réside dans l'encombrement important qu'elle présente et dans la capacité limitée de stockage de projectiles.Such systems are not entirely satisfactory either, since the main drawback of a barrel reserve lies in the large size which it presents and in the limited capacity for storing projectiles.

Par ailleurs, il est nécessaire de prévoir dans le barillet des moyens d'immobilisation spécifiques aux projectiles qui, dans certains cas, peuvent présenter des formes extérieures variables, tout en répondant à un critère global de même calibre.Furthermore, it is necessary to provide in the barrel specific means of immobilization for projectiles. which, in certain cases, can present variable external forms, while meeting a global criterion of the same caliber.

La présente invention vise à remédier à l'inconvénient ci-dessus en proposant un nouveau dispositif d'alimentation pour le tir en semi-automatique par gaz comprimé de projectiles de formes diverses.The present invention aims to remedy the above drawback by proposing a new supply device for the semi-automatic firing by compressed gas of projectiles of various shapes.

L'objet de l'invention est de proposer un nouveau système d'alimentation permettant de conduire à la mise à poste d'un projectile à tirer par une simple intervention sur la détente de commande ordinaire et sans qu'il y ait un risque d'une amorce de double introduction de tels projectiles dans la chambre de lancement.The object of the invention is to provide a new supply system making it possible to set up a projectile to be fired by a simple intervention on the ordinary control trigger and without there being a risk of 'a primer of double introduction of such projectiles into the launching chamber.

Un objet supplémentaire de l'invention est de proposer un dispositif d'alimentation permettant d'obtenir, au cours d'une seule manoeuvre, l'introduction ou la mise à poste d'un projectile puis, ensuite, son tir sans risque de fausse manoeuvre.An additional object of the invention is to propose a feeding device making it possible to obtain, during a single maneuver, the introduction or the setting in position of a projectile then, then, its shooting without risk of false maneuver.

Un autre objet encore de l'invention réside dans le fait qu'il est possible d'assumer les différentes fonctions ci-dessus avec des projectiles pouvant être considérés comme de même calibre général mais présentant, néanmoins, des variations de configuration extérieuresYet another object of the invention resides in the fact that it is possible to assume the various functions above with projectiles which can be considered to be of the same general caliber but which nevertheless exhibit variations in external configuration.

  • - et une gâchette à rappel élastique actionnée par la biellette d'armement et assumant une fonction de verrouillage ou de libération de l'équipage mobile.
To achieve the above goals, the supply device according to the invention is characterized in that it comprises:
  • - a supply store comprising:
    • . a projectile storage column,
    • . a transfer drawer between the column and a telescope placed in coincidence with the open section of the chamber,

La fig. 1 montre la carcasse 1 d'un appareil de tir semi-automatique à gaz comprimé tirant des projectiles non explosifs, par exemple du type de ceux en métal malléable. Un tel appareil peut être du type des pistolets cloueurs ou, encore, de celui des armes d'entraînement ou de sport. Dans ce dernier cas il peut s'agir de carabines ou de pistolets au sens de la définition des armes.Fig. 1 shows the carcass 1 of a semi-automatic compressed gas firing device firing non-explosive projectiles, for example of the type of those made of malleable metal. Such an apparatus can be of the type of nail guns or, again, that of training or sporting weapons. In the latter case it may be rifles or pistols as defined in the definition of weapons.

La carcasse 1 supporte un boîtier 2 contenant l'ensemble du mécanisme ainsi qu'un canon de lancement 3 offrant, à l'intérieur du boîtier, une chambre 4. Le boîtier 2 comporte, par exemple à sa partie supérieure, un raccord 5 pour le montage d'une réserve de gaz comprimé 6 pouvant être constituée par une cartouche de tout type convenable. Le raccord 5 débouche dans une capacité de transfert 7 qui communique par un conduit 8 avec la chambre 4. Le conduit 8 est contrôlé par un obturateur 9 du type à clapet ou à piston sollicité en permanence en fermeture par un organe élastique 10. L'obturateur 9 est prolongé par une aiguille de commande Il débouchant dans un alésage 12 ménagé par le boîtier 2. L'alésage 12 est réservé au passage d'un percuteur 13, du type lancé, qui est porté par un équipage mobile 14 disposé dans l'axe du canon 3 à distance de la partie arrière de ce dernier, c'est-à-dire celle offrant la chambre 4. L'équipage 14 comprend un chariot 15 guidé en coulissement axial dans une glissière 16 que présente le boîtier 2. Le chariot 15 supporte une tige 17 cylindrique dont l'extrémité postérieure est munie d'une butée 18. Un ressort 19 est monté concentriquement sur la tige 17 entre la butée 18 et la partie antérieure 20 du chariot 15, de manière à solliciter toujours la tige 17 en déplacement dans le sens de la flèche fI. Le ressort 19 est de force inférieure à celle du ressort 10. La tige 17 représente la queue d'un piston d'introduction 21 qui est orienté en direction de la chambre 4 du canon 3. Le piston 21 est associé, à sa base, à une barrette de transfert 22 comprenant une âme 23 qui est libre de coulisser axialement sur la queue 17 en étant disposée entre la base du piston 21 et la face antérieure du chariot 15. La barrette de transfert comprend une branche 24 s'étendant en direction du canon 3 parallèlement à l'axe de ce dernier, en étant décalée latéralement. La branche 24 forme une rampe d'introduction 25 dont la fonction apparaîtra dans ce qui suit.The carcass 1 supports a housing 2 containing the entire mechanism as well as a launching barrel 3 offering, inside the housing, a chamber 4. The housing 2 comprises, for example at its upper part, a connector 5 for mounting a reserve of compressed gas 6 which may consist of a cartridge of any suitable type. The connector 5 opens into a transfer capacity 7 which communicates via a conduit 8 with the chamber 4. The conduit 8 is controlled by a shutter 9 of the valve or piston type permanently urged to close by an elastic member 10. The shutter 9 is extended by a control needle It opens into a bore 12 formed by the housing 2. The bore 12 is reserved for the passage of a striker 13, of the launched type, which is carried by a mobile assembly 14 arranged in the 'axis of the barrel 3 at a distance from the rear part of the latter, that is to say that offering the chamber 4. The crew 14 comprises a carriage 15 guided in axial sliding in a slide 16 presented by the housing 2. The carriage 15 supports a cylindrical rod 17 the rear end of which is provided with a stop 18. A spring 19 is mounted concentrically on the rod 17 between the stop 18 and the front part 20 of the carriage 15, so as to always stress the rod 17 moving in the direction of f licks f I. The spring 19 has a force less than that of the spring 10. The rod 17 represents the tail of an introduction piston 21 which is oriented towards the chamber 4 of the barrel 3. The piston 21 is associated, at its base, to a transfer bar 22 comprising a core 23 which is free to slide axially on the shank 17 while being disposed between the base of the piston 21 and the front face of the carriage 15. The transfer bar comprises a branch 24 extending in the direction of the barrel 3 parallel to the axis of the latter, being offset laterally. The branch 24 forms an introduction ramp 25 whose function will appear in the following.

Le dispositif d'alimentation compren1, par ailleurs, une détente 26 montée articulée par un axe 27 sur le boîtier 2. La détente 26 est prolongée à l'intérieur du boîtier par un levier 28 articulé par un axe 29 à une biellette d'armement 30 apparaissant en traits mixtes à la fig. 1 et, plus précisément illustrée aux fig. 2 et 3. La biellette d'armement 30 est, par ailleurs, montée sur un tourillon 31 formé par l'âme 23 de la barrette de transfert 22. Au-delà du tourillon 31, la biellette d'armement forme une branche 30a s'étendant vers l'arrière dans l'alignement d'un têton 32 formé par une gâchette 33 montée libre de pivoter sur un axe 34 porté par le boîtier 2. La gâchette 33 est disposée en dessous du piston 21 et comporte un ergot 35 destiné à venir coopérer, en tant que butée de retenue, avec la partie antérieure du chariot 15. La gâchette 33 est associée à un organe élastique 36 la sollicitant en permanence en pivotement dans le sens pour lequel l'ergot 35 est placé sur la trajectoire du chariot 15. Les fig. 2 et 3 montrent que la biellette d'armement s'étend latéralement à la branche 24 de la barrette 22 qu'elle chevauche en partie, afin de constituer un élément de guidage et de butée s'opposant à la rotation de l'âme 23 sur la queue 17 du piston 21.The supply device comprises, moreover, a detent 26 mounted articulated by an axis 27 on the housing 2. The detent 26 is extended inside the housing by a lever 28 articulated by an axis 29 to a cocking rod 30 appearing in dashed lines in FIG. 1 and, more precisely illustrated in FIGS. 2 and 3. The cocking rod 30 is, moreover, mounted on a pin 31 formed by the core 23 of the transfer bar 22. Beyond the pin 31, the cocking rod forms a branch 30a s extending backwards in line with a pin 32 formed by a trigger 33 mounted free to pivot on an axis 34 carried by the housing 2. The trigger 33 is arranged below the piston 21 and comprises a lug 35 intended to come to cooperate, as a retaining stop, with the front part of the carriage 15. The trigger 33 is associated with an elastic member 36 which urges it permanently in pivoting in the direction for which the lug 35 is placed on the path of the carriage 15. FIGS. 2 and 3 show that the cocking rod extends laterally to the branch 24 of the bar 22 which it partially overlaps, so as to constitute a guide and stop element opposing the rotation of the core 23 on the tail 17 of the piston 21.

Le dispositif comprend, par ailleurs, un magasin de stockage 37 destiné à être monté et maintenu, par exemple par un levier 38, dans un logement 39 présenté par la carcasse 1 et/ou le boîtier 2. Le magasin 37, tel qu'illustré schématiquement par la fig. 4, est conformé pour délimiter intérieurement une colonne de stockage 40 destinée à contenir des projectiles 41 pouvant être introduits dans la colonne 40 par une fenêtre de garnissage 42. La fig. 1 montre que cette fenêtre peut être exécutée pour assumer une fonction de détrompage dans le cas où les projectiles utilisés n'ont pas de caractère symétrique par rapport à un plan transversal médian.The device further comprises a storage magazine 37 intended to be mounted and maintained, for example by a lever 38, in a housing 39 presented by the carcass 1 and / or the housing 2. The magazine 37, as illustrated schematically by fig. 4, is shaped to internally delimit a storage column 40 intended to contain projectiles 41 which can be introduced into the column 40 by a packing window 42. FIG. 1 shows that this window can be executed to assume a keying function in the case where the projectiles used are not symmetrical in relation to a median transverse plane.

La colonne 40 est associée à un élévateur à ressort 43 manoeuvrable manuellement lors de l'opération de garnissage. L'élévateur 43 est chargé de pousser l'empilement de projectiles 41 occupant la colonne 40 vers un tiroir 44 de transfert et de présentation occupant la partie supérieure ou tête du magasin 37. Le tiroir 44 est susceptible d'occuper, contre l'action d'un organe élastique 45 du type épingle, deux positions stables dans lesquelles il présente un logement 46, soit dans l'axe et au-dessus de la section ouverte de la colonne 40, soit en coincidence avec une lunette 47 ménagée dans la tête du magasin 37, selon un axe perpendiculaire à celui de la colonne 40 et décalé latéralement par rapport à cette dernière.Column 40 is associated with a spring elevator 43 which can be operated manually during the packing operation. The elevator 43 is responsible for pushing the stack of projectiles 41 occupying the column 40 towards a drawer 44 for transfer and presentation occupying the upper part or head of the magazine 37. The drawer 44 is capable of occupying, against the action an elastic member 45 of the pin type, two stable positions in which it has a housing 46, either in the axis and above the open section of the column 40, or in coincidence with a telescope 47 formed in the head of the magazine 37, along an axis perpendicular to that of the column 40 and offset laterally relative to the latter.

Le logement 39 est prévu pour que la lunette 47 soit placée en permanence en coïncidence de la section ouverte de la chambre 4 et pour que le tiroir 44 occupe un plan correspondant sensiblement à celui de la branche 24 de la barrette de transfert 22. En outre, ce logement 39 est ménagé de manière que la tête du magasin soit placée entre la section ouverte de la chambre 4 et le piston 21.The housing 39 is provided so that the telescope 47 is permanently placed coincident with the open section of the chamber 4 and so that the drawer 44 occupies a plane corresponding substantially to that of the branch 24 of the transfer bar 22. In addition, this housing 39 is arranged so that the head of the magazine is placed between the open section of the chamber 4 and the piston 21.

Le dispositif d'alimentation décrit ci-dessus fonctionne de la façon suivante.The feeding device described above operates as follows.

En considération de la fig. 1, le ressort 36 maintient la gâchette 33 dans sa position basculée vers le haut dans laquelle l'ergot 35 prend appui sur l'âme 23 et représente une butée pour le chariot 15. L'équipage mobile 14 est maintenu en position de recul arrière dans laquelle le piston d'introduction 21 est situé en retrait du magasin 37.In consideration of fig. 1, the spring 36 maintains the trigger 33 in its upwardly tilted position in which the lug 35 bears on the core 23 and represents a stop for the carriage 15. The movable assembly 14 is held in the rear recoil position in which the introduction piston 21 is set back from the magazine 37.

Le magasin 37, convenablement garni en projectiles 41, est immobilisé en position stable par le levier 38. Dans cet état, le tiroir de transfert occupe la position selon la fig. 4 en offrant le logement 46 dans l'axe de la colonne 40. Sous l'action de l'élévateur 43, le premier projectile 41 est introduit dans le logement 46.The magazine 37, suitably packed with projectiles 41, is immobilized in a stable position by the lever 38. In this state, the transfer drawer occupies the position according to FIG. 4 by offering the housing 46 in the axis of the column 40. Under the action of the elevator 43, the first projectile 41 is introduced into the housing 46.

Si le tireur exerce une action dans le sens de la flèche f23 sur la détente 26, la branche 28 sollicite la biellette d'armement dans le sens de la flèche f3. Par l'intermédiaire du tourillon 31, la biellette d'armement déplace le piston 21 et la queue 17 par rapport au chariot 15 immobilisé dans la position d'attente par l'ergot 35 de la gâchette 33. Le coulissement du piston 21 et de la tige 17 s'effectue dans le sens inverse à celui de la flèche fl,, en provoquant la mise sous compression de l'organe élastique 19.If the shooter exerts an action in the direction of the arrow f 23 on the trigger 26, the branch 28 urges the cocking rod in the direction of the arrow f 3 . Through the pin 31, the cocking rod moves the piston 21 and the tail 17 relative to the carriage 15 immobilized in the waiting position by the lug 35 of the trigger 33. The sliding of the piston 21 and the rod 17 is performed in the opposite direction to that of the arrow f l ,, by causing the elastic member 19 to be placed under compression.

Le déplacement du piston 21 et de la barrette de transfert 22 a pour effet d'amener la rampe 25 à agir sur le tiroir 44 pour le déplacer dans le sens de la flèche f4 (fig. 4). Ceci a pour effet d'amener le logement 46 garni en coïncidence de la lunette 47, au moment où le piston 21 arrive dans une phase d'introduction. Le projectile 41, garnissant le logement 46, est de la sorte convenablement présenté face à la chambre 4 puis introduit dans cette dernière par le piston 21 le sollicitant en poussée axiale, comme cela apparait à la fig. 5.The displacement of the piston 21 and of the transfer bar 22 has the effect of causing the ramp 25 to act on the slide 44 to move it in the direction of the arrow f 4 (fig. 4). This has the effect of bringing the housing 46 lined up coincident with the telescope 47, when the piston 21 arrives in an introduction phase. The projectile 41, lining the housing 46, is thus suitably presented facing the chamber 4 and then introduced into the latter by the piston 21 urging it in axial thrust, as appears in FIG. 5.

Dès que la mesure de déplacement axial de l'âme 23 de la barrette 22 est suffisant, l'ergot 35 s'engage entre elle et la face antérieure du chariot 15 par rotation de la gâchette 33 sous l'action du ressort 36.As soon as the measurement of axial displacement of the core 23 of the bar 22 is sufficient, the lug 35 engages between it and the front face of the carriage 15 by rotation of the trigger 33 under the action of the spring 36.

A supposer que dans cet état le tireur relâche son action sur la détente 26, le piston 21 est sollicité dans le sens de la flèche fI par la restitution de travail emmagasinée par le ressort 19. Le recul du piston ne peut toutefois intervenir au-delà de la butée que représente l'ergot 35 prenant appui contre le chariot 15. De la sorte, le piston 21 reste engagé, au moins en partie, dans le logement 46 du tiroir 44 maintenu par la rampe 25 dans la position de présentation d'un projectile face à la chambre 4, comme cela ap--parait à la fig. 6.Assuming that in this state the shooter releases its action on the trigger 26, the piston 21 is biased in the direction of the arrow f I by the work restitution stored by the spring 19. The recoil of the piston cannot however intervene beyond the stop represented by the lug 35 bearing against the carriage 15. In this way, the piston 21 remains engaged, at least in part, in the housing 46 of the drawer 44 held by the ramp 25 in the presentation position d 'a projectile facing chamber 4, as it appears in fig. 6.

Ceci représente une sécurité positive s'opposant à tout risque de tentative de présentation et d'introduction de deux projectiles successifs, lorsque le tir du premier n'est pas intervenu par suite d'une action de trop faible amplitude sur la détente 26.This represents positive security opposing any risk of attempt to present and introduce two successive projectiles, when the firing of the first has not occurred as a result of an action of too low amplitude on the trigger 26.

A supposer que le tireur poursuive son action dans le sens de la flèche f2 sur la détente 26, la branche 30a de la biellette d'armement 30 prend contact avec l'ergot 32 et sollicite alors la gâchette 33 en pivotement inverse contre l'action du ressort 36. Ceci a pour effet d'effacer l'ergot 35 par rapport à la face antérieure du chariot 15 qui est ainsi lancé en coulissement par le ressort 19 jusqu'à retrouver l'appui positif en contact avec l'âme 23 de la barrette 22. Le percuteur 13 est ainsi déplacé dans le même sens dans l'alésage 12 et vient percuter l'aiguille 11 de l'obturateur 9. Cette percussion intervient lorsque le projectile 41 est totalement introduit dans la chambre 4. L'ouverture de l'obturateur 9 délivre alors une charge de gaz comprimé amenée par le conduit 8, dans la partie arrière de la chambre 4 fermée par la tête du magasin 37 et par le piston 21. Cette charge de fluide comprimé produit le lancement du projectile astreint à suivre le canon 3.Assuming that the shooter continues his action in the direction of the arrow f 2 on the trigger 26, the branch 30a of the cocking rod 30 makes contact with the lug 32 and then requests the trigger 33 in reverse pivoting against the action of the spring 36. This has the effect of erasing the lug 35 relative to the front face of the carriage 15 which is thus slidably launched by the spring 19 until it finds the positive support in contact with the core 23 of the bar 22. The striker 13 is thus moved in the same direction in the bore 12 and strikes the needle 11 of the shutter 9. This percussion occurs when the projectile 41 is completely introduced into the chamber 4. The opening of the shutter 9 then delivers a charge of compressed gas brought by the conduit 8, in the rear part of the chamber 4 closed by the head of the magazine 37 and by the piston 21. This charge of compressed fluid produces the launching of the projectile compelled to follow canon 3.

La charge de fluide comprimé issue de la réserve 6 est délivrée pendant un bref instant, étant donné que le ressort 10 possède une force supérieure à celle du ressort 19. Dès que l'énergie cinétique résultant du lancement de l'équipage 14 a été absorbée, le ressort 10 repousse l'obturateur 9 qui interrompt la communication entre la réserve 6 et la chambre 4.The compressed fluid charge from reserve 6 is delivered for a short time, since the spring 10 has a force greater than that of the spring 19. As soon as the kinetic energy resulting from the launching of the crew 14 has been absorbed, the spring 10 repels the shutter 9 which interrupts the communication between reserve 6 and room 4.

Dans la phase de fonctionnement ci-dessus, il est indiqué que l'opérateur agit, dans un premier temps, pour produire la présentation et l'introduction d'un projectile puis, dans un second temps, pour assurer le lancement et le tir de ce dernier. Il doit être considéré que ces deux phases successives se déroulent en fait en enchaînement continu, à partir du moment où l'opérateur exerce une action également continue sur la détente 26, dans le but de lui faire parcourir toute la course utile qui lui est dévolue.In the above operating phase, it is indicated that the operator acts, firstly, to produce the presentation and introduction of a projectile, then, secondly, to launch and fire this last. It must be considered that these two successive phases actually take place in continuous sequence, from the moment when the operator exerts an equally continuous action on the trigger 26, with the aim of making it travel the entire useful travel which is devoted to it .

Lorsque l'utilisateur relâche son action sur la détente 26, le ressort 19 sollicite la tige 17, le piston 21 et l'âme 23 dans le sens de la flèche f1 et ramène l'équipage mobile 14 dans la position extrême de recul arrière, tel qu'illustré par la fig. 1. l'âme 23 est de nouveau appliquée contre la face antérieure du chariot 15, de sorte que le piston 21 est dégagé du logement 46, alors que la rampe 25 s'efface par rapport au tiroir 44. Le ressort 45 ramène le tiroir dans la position de chargement d'ua nouveau projectile poussé par l'élévateur 43 dans le logement 46.When the user releases his action on the trigger 26, the spring 19 urges the rod 17, the piston 21 and the core 23 in the direction of the arrow f 1 and brings the mobile assembly 14 back to the extreme rearward position , as illustrated in fig. 1. the core 23 is again applied against the front face of the carriage 15, so that the piston 21 is released from the housing 46, while the ramp 25 is erased relative to the drawer 44. The spring 45 brings the drawer back in the loading position of a new projectile pushed by the elevator 43 into the housing 46.

Le retour en position de recul arrière de l'équipage mobile 14 autorise le pivotement de la gâchette 33 sous l'action du ressort 36, de manière à ramener l'ergot 35 en position de butée par rapport à la face antérieure du chariot 15 et en contact avec l'âme 23.The return to the rear recoil position of the mobile assembly 14 authorizes the pivoting of the trigger 33 under the action of the spring 36, so as to bring the lug 35 in the abutment position relative to the front face of the carriage 15 and in contact with the soul 23.

L'ensemble du dispositif d'alimentation est alors prêt à fonctionner une nouvelle fois, comme décrit ci-dessus dès que l'opérateur agit sur la détente 26.The entire supply device is then ready to operate again, as described above as soon as the operator acts on the trigger 26.

Un fonctionnement en mode semi-automatique est donc possible, à partir d'un magasin de stockage garni de projectiles à caractères indépendants les uns des autres et d'une réserve de fluide comprimé.Operation in semi-automatic mode is therefore possible, from a storage magazine stocked with projectiles with independent characters from each other and from a reserve of compressed fluid.

Le dispositif d'alimentation représente un ensemble fiable, robuste, peu onéreux, capable d'assurer l'alimentation au sens général de projectiles de formes extérieures diverses, mais de même calibre, sans risque de double introduction et d'enrayage par suite de fausse manoeuvre.The feeding device represents a set reliable, robust, inexpensive, capable of supplying, in the general sense, projectiles of various external shapes, but of the same caliber, without the risk of double introduction and of slipping as a result of false maneuver.

Le dispositif d'alimentation est tout particulièrement destiné à être mis en oeuvre pour l'alimentation d'armes tirant des balles en matière malléable et qui sont utilisées pour la pratique du tir sportif ou d'entraînement, ainsi que pour l'apprentissage au maniement d'armes de combat.The feeding device is particularly intended to be used for feeding weapons firing balls of malleable material and which are used for the practice of sport shooting or training, as well as for training in handling. combat arms.

L'invention n'est pas limitée à l'exemple décrit et représenté, car diverses modifications peuvent y être apportées sans sortir de son cadre. Il doit être considéré que tout équivalent technique peut être substitué aux moyens décrits et représentés. C'est ainsi que le dispositif pourrait comporter un percuteur du type frappé.The invention is not limited to the example described and shown, since various modifications can be made without departing from its scope. It should be considered that any technical equivalent can be substituted for the means described and represented. Thus the device could include a striker of the struck type.
