Description

Sleeveless unit The invention relates to a sleeveless unit with a projectile, which is at the same time a fuse carrier and an ignition abutment, and with one compressed propellant charge enveloping the projectile. In the case of the state-of-the-art In the ammunition, the compressed propellant charge is glued to the projectile. (Daisy caseless Cal. .22 by Jules Van Langehoven and Austrian hül =; genless lsIunition with Spark ignition) With a different design, the extended slotted Bullet jacket clamped to the compressed propellant charge (French patent = writing No .: 525 623). With these arrangements it happens again and again that the pressed Propellant charge breaks off while loading from magazines or belts; since they are very strong is subjected to bending. Fine use in 'machine weapons is therefore excluded: In the case of ammunition, which also belongs to the state of the art, it is proposed that instead of the sleeves made of Xetall or cardboard, a pyrotechnic substance in the form of a To use the hose, which is internally divided into precise projectiles, loads and Contains detonator, unwound from a drum, the '' 'monkey zuöefi; hears and accordingly cut off the charge sharing. :will. ('_'` German patent no.: 618 3o9 E1. 72d G1 o2). The difficult loading process and make a weatherproof storage Also here a combat-related use is impossible.

-Task of the present ": rfindung is to form ammunition from =, which are fired without interference from machine guns or other firearms can and still contains all the advantages of sleeve-less ammunition. e.g. cheapest production, saving valuable @ materials (hupfer), greater performance, reduction of the '1 @ unition2gewichtes so that the shooter more:;' uniticn in his equipment can carry. -'Tm the rough one To enable use even in combat1 the packaging used at the same time as a hagazin. '-This also guarantees perfect weatherproof storage.

This task .is achieved by the :: rfindung that:., A Projectile 2, which is at the same time a fuse carrier and an ignition abutment, in a firing direction open, compressed propellant charge is so compressed that it has the necessary ignition resistance supplies. The primer is attached to the floor of the storey. Larger for storeys Caliber, a z; ind cap is crimped into the bottom of the projectile and into the tail cone Sawed in ignition slots. (Similar to 'Deutsche iStentschrift'; r .: 1c2 Q17 K: 1 72) To achieve better ignition of the pressed propellant charge is an ignition bridge provided by loose powder. This is in a chamber-like 'extension around' the Primer distributed. A pressed powder plate forms the cut. To this Ignition = bridge can be dispensed with if a correspondingly strong ignition charge is used will. The final powder flake is then omitted, the pressed propellant charge is a cup. The cross-sectional shape of the propellant charge can also be circular be square. In the case of a square shape, an approx. 27 '-' larger amount of powder can be used be accommodated. E.g. a circle of 2o ran @ has 31: 1. mm 2, a square with same 0 4oo'rrm2.

In a further embodiment of the invention, the bullet jacket is preferably made of plastic in order to protect the barrel and prevent metal from settling (copper-plating). Bullets for hunting and sport have a normal structure. All projectiles mentioned up to then:; earth rides twist fired. When firing, the firing pin ignites the mass and at the same time pushes the projectile (in the case of handguns and handguns) out of the compressed propellant charge into the free-flight position in front of the barrel mouthpiece. The gas pressure that then develops drives the projectile out of the barrel under normal conditions. In the case of medium and heavy floors, the above-mentioned bridge also serves as a propellant to bring the floor into the free position. On the. Drawings are exemplary embodiments of the `;; rfindüng shown with the respective bottom view.
