Definitions

  • ABSTRACT A device for simplifying the handling of case-less cartridges, said device comprising a cassette composed of two halves made of frangible or fragile material and forming a compartment for each cartridge, said cassette when completely filled with new cartridges being pushed down into a magazine by means of an auxiliary guiding frame or cover that has resilient means for advancing the cassette.
  • the compartment has walls which include wedge-like cartridge shouldersupporting means that convey to said walls a lateral force, breaking up or dividing each cassette compartment as the cartridge emerges from the magazine.
  • Each cartridge is pushed under the action of an advancing cartridge seating means such as a breech block during firing procedure.
  • the present invention relates to a plug-in magazine charger having cartridge feeding and seating facility for automatic guns of the kind that can use case-less ammunition.
  • the invention contamplates the provision of a cassette adapted for case-less cartridges and formed of two facially assembled blocks, each of which has semi-cylindrical grooves for co-operating in providing cylindrical chambers or compartments for the cartridges, said blocks being composed of a fragile or frangible manteral, the wall thickness of the deepest part of the grooves in each half being relatively thin and being such that the blocks are weakened at the sides and are separated or broken off when the breech block advancesa shoulder-type cartridge through one of the compartments. the walls of the compartments having supporting wedge-type heels that convey lateral breaking force to the walls around the cartridge.
  • FIG. 1 shows an exploded view of a magazine plug-in cassette
  • FIG. 2 is a side view of a portion of a cassette showing some details of the same more clearly.
  • a projectile 1 directly connected to a propelling charge 2 provided with a shoulder plate 2a in its front end and having a percussion cap 3 in its rear end.
  • This cartridge is intended to be introduced and seated in a barrel 4 that is shown in dotted lines in FIG. 1.
  • the cartridges are stored in a cassette that is composed of two block halves 5, each of said halves having a number of semicylindrical grooves 15 of such a depth that the walls become very thin around the deepest part8 of each of the grooves.
  • the cassette is thus capable of being broken off at these weakened areas.
  • each groove 15 Provided in the upper half of each groove 15 is a small wedge-like heel or lug 10 that abuts against and forms a stop for the shoulder plate 2a on a cartridge, thus preventing the cartridge from being thrust forwardly during firing preparation.
  • the surfaces of the block halves that are in contact with one another can be provided with a tongue and slit arrangement 6, 7. That is to say, one of the cassette halves is provided with the slits 6 and the other half has the tongues 7 that fit into the slits when the two halves of the cassette are facially placed together to form the required cylindrical chambers for the cartridges.
  • the cassette halves 5 are kept together by means of a cassette holder or frame 9 that is preferably composed of thin sheet steel or some other strong material.
  • the frame 9 preferably has a U-shaped section with the result that the edges of the frame form a resilient champing grip around the cartridge-filled cassette.
  • the gunner In using a filled cassette, the gunner removes the lacquer coating by ripping off a projecting tab that is provided for the purpose. The gunner then brings the framed package which includes the filled cassette to a magazine opening in the gun which has guiding grooves. He inserts the cassette fully down to the bottom of the magazine and he pulls away the then empty frame 9.
  • the magazine spring (not shown) serves to advance the pack of loaded cartridges so that each cartridge in the top compartment is inserted into the barrel by the forward movement of the breech block.
  • the shoulder plate 2a of the cartridge then drives the heels 10 sidewardly so that the walls of the compartment will fold outwardly and will break along the weakened lines in the deeper part of each groove such part being indicated at 8 in FIG. 1. In this manner each advancing cartridge is protected from damage all the way from the magazine storage up to the moment when it is inserted and is seated in the barrel end.
  • a cassette carrier for protectively carrying and positioning caseless cartridges for use in a weapon having a safe cartridge feeding mechanism and a breech block seating operator for said cartridges,
  • said cassette having a plurality of separate compartments, one for each cartridge, and comprising two co-fitting members of frangible material, each -member having a sequence of parallel closelyspaced semi-circular grooves, with the grooves of the two members facing and mating to define the separate compartments, and with each compartment serving to accommodate a cartridge having a front projectile connected to a propelling charge behind the projectile, with the charge provided with a shoulder plate of forwardly convergingly tapered conical shape at its front end, the forward end of each compartment wall at the upper forward edge in each groove being shaped to have a boss portion axially inclined forwardly and inwardly toward the axis of the compartment to serve as a stop to hold a cartridge against casual forward displacement, and said boss portion later serving as a wedge to generate a lateral force with a maximum halfdiameter moment arm relative to the line of the thin wall section at the bottom of its groove, when the cartridge is pressed forward to operating position by the breech block operator, whereby the front tapered shoulder plate of
  • each of the two halves of the cassette that face one another has connecting walls between the grooved walls of adjacent cartridge compartments, said connecting walls being provided with suitable sealing barrier means consisting of tongues on one half cassette and slits on the other half cassette, in which the tongues fit into the facing slits to prevent the spread of ignition fire from one cartridge compartment to another in the eassette.
  • a cassette device wherein the two halves of the cassette are held together temporarily as a package by a holding and loading frame that has a U-shaped cross section, said frame being temporarily fitted over one edge of the filled cartridge package, and said loading frame serving for pushing the cassette fully down into the bottom of the gun magazine, after which said frame is removed from the cassette and the magazine.
  • a cassette for holding a plurality of case-less cartridges comprising, a pair of grooved halves fitted together in facial relation so that the grooves therein cooperate in forming cylindrical, sequential parallel open-end cartridge compartments whose arcuate walls are connected by short wall sections, each compartment to receive a cartridge having a front shoulder, and each compartment wall being provided at its front end with a projection boss against which said shoulder on a cartridge abuts, one of the halves being provided with slits in the connecting wall sections between its grooves, the other half having tongues in the connecting wall sections between its grooves for entry into the slits when the two halves of the cassette are facially placed together, and both of the halves having weakened linear wall regions at the bottoms of their grooves for the separation of parts of the halves pressed by a cartridge shoulder when a cartridge is moved out of a groove.
  • a cassette device including a protective cover for a cartridge-filled cassette, said cover comprising a channel-shaped member having parts fitting over the top and over a side of the filled cassette, with both halves fitted together, and the cover removable after insertion of the cassette to operation position.
