Definitions

  • the present invention relates to automatic firearms adapted to be supplied with cartridges which are not connected together, i. e. which are not mounted on a belt, a clip, etc.
  • the cartridges are generally fed to the breech mechanism through a passage in which the cartridges are freely juxtaposed in direct contact with one another, in one or more rows.
  • Suitable elastic means ensure the movement of the cartridges toward the firearm breech mechanism.
  • the object of the present invention is to eliminate these disadvantages. Its essential feature consists in making the portion of the above mentioned passage adjacent to the breech mechanism elastically expansible so as to absorb the accelerations imparted to the first cartridges of the row and to permit a feed movement of the remainder of the row or rows of cartridges at substantially uniform velocity.
  • Fig. 1 is a sectional elevation of a first embodiment.
  • Fig. 2 is a plan view corresponding to Fig. 1.
  • Figs. 3 and 4 are sectional elevations of two other embodiments.
  • the cartridge feed device illustrated by Figs. 1 and 2 is made as follows:
  • the passage for guiding cartridges I2 includes a rear portion II the opposite walls of which are at a distance from each other corresponding ex- 2 actly to the thickness of the cartridges, and a front portion I! the opposite walls of which converge toward an outlet I3 the dimensions of which correspond to those of portion I I.
  • a space I6 where there are no continuous walls for guiding the cartridges but levers I8, pivoted at I9 to portion II and engaging in slots Ila of walls I'I, these levers being urged inwardly by springs 20 mounted'on portion I I. Stops 24 carried by portion I'l limit outward displacements of levers I8.
  • the device operates in the following manner:
  • Pusher 2I acts to hold all the cartridges in contact with one another and to press the first cartridge 23 against breech block I5.
  • the cartridges assume a zigzag or staggered formation and tend to force levers I8 into contact with stops 24.
  • levers I8 When breech block I5 is retracted to admit the first cartridge 23 into the breech case, the introduction of this cartridge is facilitated by the action of levers I8 which, on pivoting inwardly, impart a sudden acceleration to the cartridges located between portion I6 of the passage and the breech case.
  • feeds all the cartridges contained in the passage toward the breech case.
  • levers l8 are not indispensible to arrange levers l8 on both sides of section I6. The same result can be obtained by providing levers on one side only of this section. Instead of actuating levers I8 by springs 20. I may also control the movement of these levers in synchronism with the distributing mechanism of the firearm through any suitable transmission device.
  • Fig. 3 difiers from that of Figs. 1 and 2 in that one of the guiding members between the edge of passage portion H and the corresponding edge of outlet I3 is fixed, being constituted by curvilinear part 23.
  • the opposite guiding wall includes arms I8a pivoted at I9a to a part Ila fixed with respect to part II and I3.
  • Springs 20 urge arms I 8a toward their positions shown in solid lines on Fig. 3.
  • the third embodiment shown in Fig. 4 is practically identical with that of Fig. 1, with the only difference that portion H of the passage is dimensioned to accommodate two rows of cartridges arranged in staggered relation. Operation is identical with that of the first embodiment.
  • the conversion of the sudden movement of the first cartridges to leave the device into a substantially continuous movement for the remainder of the cartridges in the device is obtained by providing an expansible portion in proximity to the outlet thereof.
  • a cartridge feed device for automatic firearms to be supplied with cartridges which are not connected together which comprises, in combination, means forming a guiding housing for at least one row of cartridges, said means in cluding, an outlet end of said housing, two walls at said outlet end fixed with respect to each other at a distance from each other substantially equal to the diameter of said cartridges, two walls at the other end of said housing fixed with respect to the two first mentioned walls and extending in the direction of said row of cartridges to a distance .from said first mentioned walls, these two pairs of guiding walls being parallel to the axes of the cartridges of said row, and two guiding members elastically urged relatively to each other against the row of cartridges transversely to the direction of said row and mounted to bridge the gap between the two first mentioned guiding walls and the two second mentioned guiding walls, and means in said second mentioned end of said housing for engaging the last cartridge of said roll and urging it toward the outlet end of said housing.
  • a cartridge feed device in which said elastically movable guiding members are constituted by arms pivoted to the two second, mentioned guiding walls respectively about axes parallel to the axes of the cartridges of said row, in combination with spring means for elastically opposing outward movements of said arms.
  • a cartridge feed device in which said elastically movable guiding members are constituted by arms pivoted to the two second mentioned guiding walls respectively about axes parallel to the axes of the cartridges of. said row, in combination with spring means for elastically opposing outward movements of said arms, said arms, being rectilinear.
  • a cartridge feed device in which said elastically movable guiding members are constituted by arms at least one of which is pivoted to the two second mentioned guiding walls respectively about axes parallel to the axes of the cartridges of said row, in combination with spring means for elastically opposing outward movements of said arms, said arms being curvilinear.
