Tool for attaching and/or detaching medium-caliber ammunition within a linked chain

A system for attaching and/or detaching ammunition having the form of a linked chain or strip, comprising:

• a chain of a plurality of ammunition each having a head, a case, and a base that are essentially cylindrical, the ammunition being successively attached to one another by links, each link comprising a first part and a second part, articulated and offset relative to one another, the second part comprising a loop or ansa that is central relative to a height of the link, defining an approximately semi-cylindrical opening, dimensioned to be adjusted on the case of a cartridge of a given caliber, the first part comprising two loops of this type but situated, in terms of height, respectively on either side of the central loop, at least the central loop comprising, at its free ends, a small loop oriented in a direction opposite that of a main loop, so as to define a flare configured to allow easier insertion or removal of the cartridge, the upper loop of the first part being extended by an essentially flat and rectangular part extending upward and the lower loop of the first part being extended downward by an essentially flat part, ending with an index that is inserted into a removal groove of the ammunition;
• and
• a tool, comprising:
• a first arm and a second arm configured to be set in rotation in a plane independently of one another;
• a fixed structure configured to be placed in an upper position relative to the ammunition chain, i.e., across from the heads and having an oval geometric shape, the fixed structure comprising two through orifices;
• movable hollow cylindrical structures extending downward, arranged inside each of the respective orifices, with appropriate play, the fixed structure having an interval configured to insert and connect an arm to each of these cylindrical structures, the arm ending with a circular collar having an inner diameter the same as that of the corresponding orifice, each hollow cylindrical structure being provided on its outer edge, in a front, with a short lateral portion slightly curved to match the cylindrical shape of the case, the cylindrical structure situated on the right, seen from a front of the tool, being provided in an extension of the corresponding short portion with a finger, also slightly cylindrical and having a protuberance on its left;
• on a rear side, across from each orifice, covers forming respective grooves positioned along an axis of the fixed structure and each configured to match a shape of the upper flat of the first part of the adjacent links of the ammunition chain, the cover situated across from the hollow cylindrical structure having the finger being fastened to the fixed structure and the cover situated across from the other hollow cylindrical structure being secured to the latter and therefore rotatably movable;
• wherein, in case of attaching and/or detaching ammunition, respectively:
• at a location of the chain where one wishes to create a split, the tool device is configured to be simultaneously placed at an apex of two adjacent pieces of ammunition by inserting the respective heads into the orifices, the upper flats of the adjacent links being inserted into the grooves of the respective aforementioned covers to secure the first parts of the two adjacent links during rotation of the movable arms to the fixed structure and the other hollow cylindrical structure, respectively,
• wherein, when the movable arms are set in rotation and moved apart, brought closer to one another, respectively, the protuberance of the finger is configured to act as a lever on the ansa of the second link part surrounding the cartridge via a thrust on the small loop of that ansa situated across from the finger, to spread open the ansa at that location, the first part of the corresponding link surrounding the adjacent cartridge being configured to rotate with the adjacent cartridge owing to the other movable arm, this rotation reinforcing the spreading action of the protuberance on the small loop, and
• wherein the ansa of the link being spread, the adjacent cartridge is configured to be easily be removed therefrom, inserted therein, respectively.
