Definitions

  • the present invention relates to cartridges, and more particularly to fired cartridges for shells or grenades of guns, mortars, rocket projectors, or the like.
  • Cartridges of this type are known in the prior art in which the propellant charge is arranged adjacent to the rear of the ignition charge. With these prior art cartridges, the ignition and burning of the charge takes place from the end face thereof. The attainment of the normal burning velocity only takes place very slowly, and the burning velocity itself is also slow by reason of the small end face.
  • a central chamber extending parallel to the axis of the cartridge, is arranged in the center of the cylindrically shaped propellant charge which chamber extends through the entire propellant charge.
  • the ignition and burning of the charge then does not take place, as customary heretofore, from the end face thereof, but from this chamber.
  • the burning and consumption of the charge is correspond ingly more rapid. It is most simple from a manufacturing point of view to give to the central chamber a circularly shaped cross section.
  • the chamber may also be constructed of star-like shape which leads to a further surface increase and therewith to a further burning acceleration.
  • the chamber in accordance with the present invention is made of material that can be readily torn and/or destroyed, for example, of thin paper or plastic sheet material.
  • the chamber may also consist of a powder foil. It is, however, important that the chamber is punctured or penetrated in all places as fast as possible by the ignition or tears as evenly as possible over the entire length thereof under the ignition gas pressure.
  • Another object of the present invention resides in the provision of a cartridge of the type described above in which the propelling energy is set free considerably more instantaneously than realizable heretofore.
  • Still another object of the present invention resides in the provision of a cartridge of the type described above in which the exposed surface of the propellant charge is effectively increased.
  • Another object of the present invention resides in the provision of a cartridge to be fired or shot which is provided with a chamber on the inside of the propellant charge of such design and construction as to expose substantially instantaneously after ignition, the entire surface of the propellant charge facing this chamber to the effects of the ignition charge.
  • FIGURE 1 is a longitudinal cross-sectional view through a cartridge in accordance with the present invention
  • FIGURE 1a is an elevational view, on a reduced scale, of a cartridge similar to that of FIGURE 1;
  • FIGURE 2 is a cross-sectional view through the cartridge of FIGURE 1 taken along line IIII and provided with a chamber of circular cross section, and
  • FIGURE 3 is a cross-sectional view, similar to FIG- URE 2, taken through the cartridge along line IIII of FIGURE 1 with a chamber of star-shaped cross section.
  • reference numeral 1 designates therein the cartridge case which contains on the inside thereof, the powder 2 of the propellant charge.
  • a wall 3 is inserted into the cartridge case 1 on the inside of the propellant charge 2.
  • the powder serving the ignition; that is, the ignition charge, is designated by reference numeral 4 while reference numeral 5 designates the base portion of the cartridge and reference numeral 6 the primer or ignition cap.
  • FIGURE 1a shows the assembled cartridge in sideelevational view.
  • FIGURES 2 and 3 are cross-sectional views, through the cartridge of FIGURE 1, taken along line II- II of FIGURE 1, and illustrating the chambers with circularly shaped cross section 7 and star-shaped cross section 8, respectively.
  • a terminal cap 9 of H-shapedcross section is provided at the base portion 5 of the cartridge and a centering ring 10 at the upper end of the cartridge along the mouth of the cartridge case 1.
  • the chamber walls 3 may be constituted by any known material that tears easily or is easilydestroyed such as thin paper, plastic sheet material, powder foils or the like.
  • a cartridge comprising: a substantially tubular cartridge case; a base portion closing the rear end of said cartridge case, a relatively small igniting charge in said base portion; a substantially tubular propellant charge within said cartridge case and defining a continuous substantially axial firing channel extending substantially the entire length of said cartridge case within said propellant charge; said firing channel consisting essentially of gases and being substantially free of any explosive material; said igniting charge and said firing channel being substantially axially aligned; means, including said firing channel, being operable to conduct the combustion gases produced by the firing of said igniting charge freely over the entire length of said firing channel to substantially instantaneously ignite said propellant charge along substantially the entire internal surface; said cartridge case having a homogeneously integral forward front wall closing the entire front end of said cartridge case; said front wall having a homogeneously integral central ring means extending axially inwardly and telescopically engaged with tubular propellant charge for preventing transverse movement of the forward portion of said propellant charge; a readily destructible tubular
