Definitions

  • the invention relates to a device for supplying ammunition to an automatic firearm, which device comprises two ducts merging at their outlets into a common duct.
  • a known device of this kind serves for guiding loose cartridges not joined into a belt.
  • Two star wheels arranged at the juncture of the two ducts control the flow of cartridges in such a manner that alternately a single cartridge from one of the two ducts and from the other passes into the common duct issuing into the ammunition entrance opening of the gun.
  • Such a device is used for example for feeding a gun from two cartridge magazines.
  • the present invention has the primary object of adapting the existing devices to the guiding of separate cartridge belts.
  • I provide a device for guiding ammunition to an automatic firearm, comprising in combination: two ducts merging at their outlets into a common duct, a tongue articulated along the line of intersection of the said two ducts and capable of being adjusted at will into two positions in which it establishes alternately a connection of one of the said two ducts to the said common duct for guiding the ammunition from one of the said ducts into the said common duct.
  • I provide a gun mounting, a gun pivotally mounted about a horizontal elevation axis and about a vertical azimuth axis on the said gun mounting, an abutment on the said gun mounting performing only the azimuth laying movement of the said gun, and an abutment piece fixedly connected to the said tongue and co-operating with the said abutment for limiting the elevation laying of said gun.
  • FIG. 1 is a plan view of a gun with ammunition containers, partly broken off;
  • FIG. 2 is a part-elevation on a larger scale, partly in section on the line 11-11 of FIG. 1;
  • FIG. 3 is an elevation of the supply duct as seen from the plane lIIlll of FIG. 2.
  • FIG. 1 the annular race of an upper gun mounting is denoted by 1.
  • the gun 2 On this upper gun mounting, which is rotatable all round about the azimuth axis Z, the gun 2 is mounted in a manner not illustrated in more detail, and moreover an armour hood 3 covering the same is fixedly connected therewith as indicated in FIG. 3.
  • Y is the elevation laying axis of the gun. From the two ammunition containers 4 and 6 connected to the upper gun mounting, cartridge belts 5 or 7 are guided into the entrance opening 8 leading to the belt feeding device of the gun 2.
  • the belt 5 composed in the usual manner of links 9 articulated to one another and embracing the cartridges it) is passed upward from the ammunition container t through the outlet duct 4a forming a part of a first single duct which is directed with its longitudinal side parallel to the gun 2.
  • a circular guide track 11 is connected, the axis of rotation of which coincides with the elevation laying axis Y.
  • rollers 13 which are journalled on a circular disc 12 that is rotatable about this axis.
  • On the disc 12 guide sheet metal pieces 14, 15 are fixed, which bound a stretch 16 of the first single duct.
  • the disc 12 In the basic position of the gun, i.e. at zero elevation, the disc 12 is so positioned, that the roller 19 lies p rallel to the longitudinal side of the belt entrance opening 8 of the gun 2.
  • the belt 5 is provided for supplying ammunition to the gun for anti-aircraft defence.
  • This outlet duct 6a is continued by a stretch 20 of the second single duct.
  • a wall 20a is bent substantiallv at a right angle to the second single duct and runs towards the lower edge of the inlet opening 8, while the wall 2% is directed towards the uide sheet metal piece 15 of the disc 12 which is attached to the disc.
  • the wall 23 of a common duct 2b inclined upwardly at an angle from the entrance opening 8 ends in a semi-circular wall 25 placed parallel to the disc and fixed to the casin 21.
  • a shaft 29 is journalled to which a ton ue 30 is fixedly connected which extends over the whole width of this common duct of substantially rectangular shape 26 right to the outlet of said common duct.
  • On one end of this shaft 29 an abutment piece 31 is keyed, and on the other end thereof an actuating lever 32. which can be swung into two positions and secured by detents.
  • the ducts 20 and 26, respectively, are connected by an intermediate piece 39 fixed to the extension 27 to the cradle carrying the gun 2, and moves together with the same about the elevation laying axis Y.
  • the ends of this movable duct 20 as well as those of the stationary duct 6a of the container are rounded at a radius corresponding to their distance from the axis of rotation Y.
  • the outlet duct 6a is moreover made wider than the duct 20, so that the belt 7 is deflected without effort from the duct 611 into the inclined duct 20, when the gun is elevated.
  • the common duct 26 which is connected to the cradle and is rotatable with the same about the elevation laying axis Y drives the disc through a toothed segment 35 fixed to its wall and through a gearing not described in more detail in such a manner that the same'performs a rotation about the elevation laying axis Y, which amounts for example to half only of the elevationor depression-angle of the gun and accordingly of the common duct 26.
  • the abutment 37 fixedly connected to the armour hood 3, in the position of the tongue 30 illustrated in FIG.
  • the belt 7 When changing over from targets onthe ground to other targets needing ammunition from the container 4 for com-. batting the same, the belt 7 is left in the container 6 so far, that its foremost cartridge lies at the outlet fromthe container duct 6a, whereatter it is arrested in this position by the pawl 33.
  • the belt 5 After the readjustment of the tongue to the position indicated inchain-dotted lines (FIG. 2), the belt 5 is pulled into the gun from the position illustrated, and is secured by the pawl 34, in which position the foremost cartridge lies at the entranceto the common duct 26. With the gun elevated, that part-of the belt 5, which actu-. ally moves in the stretch 16 of the first single duct in the disc 12, istwisted relative to that part of the.
  • a gun a duct system fixedly connected to said gun for guiding ammunition to said gun
  • said duct system comprising, a common duct of substantially rectangular shape adjacent to said gun, two single ducts merging at their outlets into said common duct, a tongue articulated within said common duct and between said outlets of said two single ducts and adjustable at will into two positions in which it establishes alternately a connection of one of said two single ducts to said common duct for guiding the ammunition from one of said two single ducts into said common duct.
  • a gun mounting an abutment fixedly connected to said gun mounting, a gun pivotally mounted about a horizontal elevation axis on said gun mounting, a duct system fixedly connected; to said gun for guiding ammunition to said gun, said duct system comprising, a common duct of substantially rectangular shape adjacent to said gun, two single ducts merging at their outlets into said common duct, a tongue articulated within said common duct and between said.
  • outlets of said two single ducts and adjustable at will into two tongue positions in which it establishes alternately a connection of one of said two single ducts to said common duct for guiding the ammunition from one of said two single ducts v into said common duct, an abutment piece having a common pivot axis with said tongue and movable into two abutment piece positions for limiting in one of said two abutment piece positions the elevation laying of said gun by contacting said abutment and for letting pass in the other of said" two abutment piece positions said abutment during a higher elevation layingof said gun, a connecting means fixedly connecting said tongue to said abutment piece to coordinate the movements of said tongue and of said abutment piece.
  • a combination as set forth in claim 3 wherein said connecting means comprises a shaft journaled in the side walls of said common duct and carrying said tongue'inside said side walls and said abutment, piece outside said common duct.
