Definitions

  • This invention relates to cartridges for shot guns and has for its object to provide a cartridge capable of being recharged after use.
  • Cartridges for shot guns usually comprise a paper or like casing fitted in a brass base and said cartridges are usually closed by a paper or celluloid disc or washer which is maintained in position by setting back the outer end of the casing over a distance of about 5 to 7 mm.
  • the paper casing is sometimes torn off the brass base and sometimes swells, thereby causing jamming in the bore of the gun, so that this form of cartridge is not suitable for recharging after use.
  • the cartridge comprises a metal casing provided at its outer end with one or more internal annular grooves having a frustro conical part surmounted by a truly cylindrical part, the conical surface being inclined inwardly towards the base of the cartridge, and a closing disc dished to substantially frustro-conical shape and adapted to fit within said annular groove, or one of said annular grooves with its conical surface engaging the corresponding conical surface of the groove and its peripheral edge located in the cylindrical part of said groove.
  • the closing disc or washer is preferably composed of thin resilient metal such as light duralumin of about 0.2 mm. thickness or brass foil of about 0.15 mm. thickness.
  • Figures 1 and 2 show a cross-section and plan view respectively of the closing disc or washer of the cartridge.
  • Figure 3 is a longitudinal section of the complete cartridge.
  • Figure 4 is a section of the outer end of the cartridge casing on an enlarged scale.
  • Figure 5 is a similar view to Figure 4 with the closing disc or washer ready to be inserted and Figure 6 is a similar view showing the closing disc or washer in its final position.
  • the cartridge comprises a metal casing 4 provided in its inner end with a percussion cap and formed near its outer end with a plurality of internal annular grooves 5, E, l in which fits a closing disc or washer I.
  • the closing disc or washer l is dished as shown so as to be of substantially frustro-conical form, the conical part 2 extending upwardly when inserted in one of the grooves 5, 6 or '5.
  • Each of the grooves 5, 6 and l comprises a frustro-conical part B and a truly cylindrical part, the conical surface 8 bein inclined inwardly and downwardly towards the base of the cartridge.
  • the closin washer or disc is placed in the position shown in Figure 5 and then pressed into the position shown in Figure 6. It will be clearly understood that as the closing disc or washer l is composed of thin resilient metal, as described above, its diameter will be reduced as it is pressed into the mouth of the casing 3 and will finally snap into the groove 5 where it will be retained to the upturned peripheral flange 2 projecting into the cylindrical part of the groove.
  • the amount of powder and shot may be varied as desired.
  • a cartridge for shot guns comprising, a cylindrical metal casing provided with at least one internal annular groove near its outer end and a resilient metal disc having a fiat central circular part and an annular frustro-conical rim, the free diameter of said disc being greater than the internal diameter of said casing and fitting resiliently in said annular groove for retaining a shot and powder charge within said casing.
  • a cartridge for shot guns comprising, a cylindrical metal casing provided with at least one internal annular groove near its outer end and a resilient metal washer having an annular frustroconical rim, the free diameter of said washer being greater than the internal diameter of said casing and fitting resiliently in said annular groove for retaining a shot and powder charge within said casing.
  • a cartridge for shot guns comprising, a cylindrical metal casing provided with at least one internal annular groove near its outer end, said groove having a frustro-conical part surmounted by a cylindrical part, and a resilient metal disc having a fiat central circular part and an annular frustro-conical rim, the free diameter of said disc being greater than the internal diameter of said casing and fitting resiliently in said annular groove for retaining a shot and powder charge within said casing.
  • a cartridge for shot guns comprising, a cylindrical metal casing provided with at least one internal annular groove near its outer end, said groove having a frustro-conical part surmounted by a cylindrical part, and a resilient metal washer having an annular frustro-conical rim, the free diameter of said Washer being greater than the internal diameter of said casing and fitting resiliently in said annular groove for retaining a shot and powder charge Within said casing.
