Definitions

  • the present invention relates to a device for repeated discharge of gas-pressured projectiles, comprising a barrel and a magazine adapted for the coaxial loading of projectiles into the barrel, the region between barrel and magazine defining a space communicating with the barrel and through which gas can be introduced to forcibly eject a projectile from the barrel.
  • Tube shaped magazines for repeating and automatic target shooting weapons are known, the axes of which are either perpendicular, parallel or coaxial with the barrel of the weapon.
  • Another feeding device with a tubular magazine arranged above the barrel axis is equally complicated and unreliable.
  • a carrier by means of lateral movement, removes the shot and transfers it into the barrel.
  • deformation of the shot and unreliable operation can still occur.
  • a linear tube magazine is lined up coaxially with the barrel of the weapon, forming a unit therewith.
  • An entry cone with its top pointing into the barrel is arranged between the rear face of the barrel and the face of the magazine, and shots are forced into the entry cone from the storage magazine by a spring loaded feeder.
  • a channel for conveying the pressure medium leads to the space of the entry cone.
  • the pressure medium enters after a shot has been released into the magazine to distribute the shots so that each shot is forced out of the barrel, while the other shots remain in the magazine.
  • This arrangement is unreliable and has a substantial failure rate, as the changing pressure of the pressure medium does not ensure a specific position of the shot, so a shot may enter deeply into the barrel, partly followed by another. After shooting both shots, all remaining shots in the magazine may be forced out of the barrel.
  • a storage device for a multishot gas weapon for soft material shots with a tubular magazine coaxial with the barrel of the weapon and with a needle feeder has a special arrangement of the rear barrel face and the front end of the magazine (Czechoslovak certificate of authorship of invention No. 197.658).
  • a conical slot with the apex toward the magazine is provided between the face of the magazine and the rear face of the barrel.
  • a channel for supply of pressure medium leads into the space of said slot.
  • An entry cone with the apex pointing into the bore of the barrel is provided at the rear face of the barrel, serving for fixing and rectifying the track of the shot to the axis of the barrel.
  • the pressure medium enters through the supply channel into the conical slot between magazine and barrel, forces the shot out of the barrel, and causes the remaining shots to remain in the magazine at the moment the shot is fired. Rearward movement of the shots in the magazine is prevented by a spring loaded needle feeder with a reverse pawl. After each shot, the pressure is equalized, and the needle feeder shifts another shot into the entry cone at the rear face of the barrel. A shot is also engaged thereby into the conical slot, readying the weapon for the next shot.
  • Calibrated spherical shots can be used for this weapon, particularly the presently used Diabolo (Trade Mark) shots.
  • An advantage of this embodiment of the magazine lies in its simplicity of manufacture and that it is coaxial, the symmetrical arrangement preventing irregular deformation of the shots.
  • a drawback of this arrangement is the increased sensitivity of the dosing of shots to the accuracy of calibration of the barrel of the weapon, to parameters of the spring loaded needle feeder and to variations of the stiffness of the spring. When these parameters are changed, even more shots can be forced irregularly out of the barrel.
  • the present invention provides, in a first aspect, a device for repeated discharge of gas-pressured projectiles, comprising a barrel and a magazine adapted for the coaxial loading of projectiles into the barrel, the region between barrel and magazine defining a space communicating with the barrel and through which gas can be introduced to forcibly eject a projectile from the barrel, characterised in that the communication of the space with the barrel is via a plurality of apertures opening into the region between barrel and magazine, at least one, but not all, of which apertures also extends longitudinally into the bore of the barrel thereby to create, on actuation and in addition to the force to eject the projectile, an imbalance in the reverse force to bias the next projectile in the magazine against the wall thereof.
  • the preferred number of extended apertures, or slots is one, with a total of about 4 slots, although a pair of diametrically opposed slots, one short and one extended, can suffice, for example.
  • These slots will generally be created in a cylindrical portion of the barrel extending back from the bore to engage the magazine. This cylindrical portion is not preferably the full width of the barrel, so that the space between barrel and magazine is provided around it.
  • the rear of the barrel is substantially conical and is matched by a corresponding inverse cone in the end of the magazine, the space between them thereby being a conical slot with its apex toward the magazine.
  • connection to the gas supply is via a, particularly bevelled, slot in one wall of the magazine leading directly to the extended slot, thereby assisting directly in the creation of the imbalance in the force.
  • the retardation of shots in the magazine may be further enhanced by having the bore of the magazine, at least at the discharge end, being of greater diameter than the bore of the barrel.
  • the imbalance of the force thereby pushes the next shot against the wall of the bore, and the difference in diameters provides an additional barrier to the shot.
  • This latter effect may be further enhanced by a slight tilt of the entry to the bore of the barrel away from the extended slot.
  • a storage device in an alternative aspect, the above drawbacks are also eliminated by a storage device according to the present invention, the main feature of which is in the creation of a blow-through slot between the terminations of a tube shaped magazine and of the barrel of the weapon, whereby longitudinal slots are created in the cylindrical off set end of the barrel, into which the channel for supply of the pressure medium terminates, one of the longitudinal slots being prolonged up to the barrel, a bevelled slot being provided in the wall of the tubular magazine and engaging into the conical blow-through slot.
  • the pressure medium supplied by way of a channel into the blow-through slot forces, on actuation, a shot resting against the rear face of the barrel out of the barrel of the weapon and, by the dynamic effect in the opposite direction, prevents further shots situated in the tube shaped magazine following the first shot into the barrel of the weapon. Due to the unequal length of slots in the cylindrical off-set part of the barrel, a force in a non-axial direction is created, causing a blocking of the shots in the magazine which has a larger diameter than the largest diameter of the shots, so that they are arranged in the magazine with a certain tolerance. After the pressure in the barrel, in the blow-through slot and in the channel for the pressure medium are equalized, the shots are again axially lined up and the spring loaded feeder shifts the column of shots forward toward the rear face of the barrel of the weapon.
  • the present invention thus provides for the transfer of shots from the magazine to the barrel of the weapon with reliability and allows trouble-free shooting.
  • the gas weapon has within the sleeve of its breech 1 a tube shaped magazine 2 situated coaxially with a firmly anchored barrel 3 of the gas weapon.
  • the barrel 3 has, at its rear end, a cone 4 with a cylindrical stepped end of the barrel 5, wherein slots 6, 6a are provided.
  • a blow-through slot 8 is created between the conical end 4 of the barrel 3 and an equidistant conical end 7 of the magazine 2, said blow-through slot 8 determined by the length of the cylindrical stepped end 5 of the barrel 3.
  • the slot 6a in the cylindrical stepped end 5 of the barrel 3 is elongated and engages up to the bore of the barrel 3.
  • a bevelled slot 9 linking with the prolonged slot 6a is arranged in the conical end 7 of the magazine 2.
  • a supply channel 10 for the pressure medium terminates into the space of the bevelled slot 9.
  • the target shots 11 are situated in line in the tube shaped magazine 2 and are forced into the bore of the barrel 3 by a spring loaded needle feeder 12.
  • a dose of the pressure medium is released.
  • This medium enters by way of the channel 10 into the conical blow-through slot 8 and between the shots within the magazine 2.
  • a shot 11 resting against the rear face of the barrel 3 is forced out of the barrel 3 after overcoming the extrusion resistance.
  • the remaining shots 11 are maintained in the magazine 2 behind the conical blow-through slot 8 by the dynamic action of the pressure medium in the reverse direction which, due to the unequal lengths of slots 6, 6a in the cylindrical stepped end of the barrel 3, generates a force in an inclined direction and causes a blocking of missiles 11 in the magazine 2.
  • blow-through slot 8 and supply channel 10 After the pressure in the barrel 3, blow-through slot 8 and supply channel 10 has equalised, the shots 11 are again axially lined up and the spring loaded needle feeder 12 shifts the column of shots 11 forward toward the rear face of the barrel 3 of the weapon, whereafter the weapon is again prepared for shooting.
