DESCRIPTION:
BRIEF SUMMARY
The present invention concerns an automatic device with an interchangeable interface for the introduction of cartridges into bifilar and monofilar magazines of automatic and semi-automatic arms.
It is well known that the use of drill or professional arms continuously shows the need of refilling the magazines. This need, up to now, was solved by the completely manual cartridge introduction, or by small apparatuses being manually operated, or also by machines being limited to the filling of bifilar magazines.
It is the aim of the present invention to make the above operation completely automatic, so as to obtain the refilling in a very quick time, and in an easy and not expensive manner.
The aim set forth is achieved by means of the device according to the present invention, comprising a plate with a cartridge-guide ledge placed above a vertical track, for transferring said cartridges into a suitable seat, from which a piston introduces the same, one by one, in the arm magazine contained in the interchangeable interfaces, by means of a movable pin.
The present invention will be described more in detail hereinbelow according to the attached drawings, showing one preferred embodiment thereof.
FIG. 1, shows an axonometric view of the whole device;
FIG. 2, shows an axonometric view of an interface for bifilar magazines;
FIG. 3, shows a front view of the plate with a cartridge-guide ledge;
FIG. 4, shows a cross section of the plate with a cartridge-guide ledge;
FIG. 5, shows a cross section of the vertical track;
FIG. 6, shows the detail of the movable pin that rotates or pivots approximately 90.degree.;
FIG. 7, shows a cross section of the seat into which the cartridges fall;
FIG. 8, shows a cross section of the interface for bifilar magazines provided with movable inclined planes.
Relating now to the details of the figures, the device consist of:
a plate 1 with a cartridge-guide ledge 2;
a vertical track 3 from which the cartridges 4 come down making use of guides 5 that will get inserted in the cavity placed near the bottom of the cartridge, said cavity being provided for allowing the extraction of the same cartridge from a firearms cartridge room;
a vertical rod 6 with alternate movement with flexible tabs 7 that graze the noses of cartridges 4, so as to facilitate the sliding in track 3;
an interface 8, interchangeable according to the kind of arm magazine to be filled;
a movable pin 10 provided so that it may perform a 90.degree. revolution (i.e., rotate or pivot at a right angle) and that pushes down the cartridges 11 already contained in the magazine, exploiting the alternate movement of a press (12);
a piston 13 having the task of inserting in succession the cartridges into the arm magazine;
two arms 14 for lifting the press 12 and the pin 10;
a housing 15 for the arm magazine;
an electric motor 16 that has the task of transmitting the movement to the piston 13 with a connecting rod-handle system 17 that is able to transform the rotating into alternate movement.
The plate 1 provided with cartridge-guide ledge 2 is placed above vertical track 3 and allows the introduction of cartridges in said track using directly the cartridge boxes (containing, e.g., 50 cartridges), in which the cartridges are placed with the bottom upwardly turned. The cartridges contained in the box are placed by the operator with the bottom onto plate 1, and dragged towards the cartridge-guide ledge 2 until the first row of cartridges doesn't lean against said ledge. Now the box containing the cartridges is let down so as to allow guides 5, placed along vertical track 3, to get inserted into the cavity placed near the bottom of the cartridges, so as to engage the first row of cartridges. The box containing the remaining cartridges is taken away from the plate and the operation is repeated for each row, until the box is empty.
From plate 1 the cartridges get down directly into the vertical track 3, provided by guides 5, for transferring each single cartridge into the suitable seat 18, from which piston 13 introduces the same into the
