Definitions

  • This invention relates to explosive cartridges. More particularly it relates to cartridges which are adapted for use in providing the power means for explosively operated industrial tools.
  • FIGURE 1 is a perspective view illustrating a preferred embodiment of the present invention
  • FIGURE 2 is an assembled perspective view of the device taken along line 2-2 of FIGURE 1;
  • FIGURE 3 is an exploded perspective view similar to FIGURE 2.
  • the cartridge consists of a tubular casing comprising a cylinder closed at one end 12 and by a breech closure having a rim 13 for seating the cartridge in an igniting device.
  • the cartridge may be made of a molded plastic, e.g. polyethylene.
  • a wad 14 Positioned within the cylinder by an interference fit is a wad 14. The wad is disposed from the breeched closure 12 of the casing 10 to form a closed space 16 therewith. A quantity of explosive powder 18 is retained in the space 16.
  • the wad 14 may also be of plastic, in the same manner as the casing.
  • a flash tube 20 extends longitudinally through the wad so that its inner end communicates with the powder charge 18.
  • the outer end of the wad 14- contains a recess 22 which is concentric with the flash tube 20.
  • the recess 22 retains a cartridge primer 24.
  • the wad may be dome-shaped on its inner surface and have a circular recess 26 about its intermediate periphery. This recess functions as a gas check and traps gasses which tend to escape.
  • the cartridge When it is desired to use the cartridge (e.g. in a tool such as identified above), it is seated therein by rim 13 with the primer detonating means extending into the open end of the casing 10. The cartridge is actuated by the detonating means operating on the cartridge primer 24 in the direction of the arrow shown in FIGURE 2.
  • the explosion of the primer in turn ignites the powder charge 16. Since the cartridge is confined in the tool, the explosive force drives the wad toward the free end of the cartridge. Thus because of the inaccessibility of the primer, the cartridge cannot be detonated accidentally e.g. by dropping it or inadvertently striking it. It can only be discharged by inserting a detonating means in the free end of the cartridge and delivering energy to the priming means in such a manner calculated to cause actuation of the primer.
  • the primer is located centrally of the cartridge, the noise of detonation is muffled. Also the breech closure of the cartridge is sealed so that the only opening is in the direction of thrust. Thus there is no possibility of escape gasses leaking out through the back of the cartridge, as is possible in cartridges having a primer seated in the exterior wall.
  • a device of the character described including a tubular casing closed at one end to form a breech closure and opened at the opposite end, a powder charge in said casing adjacent the closed end thereof, a wad in said casing adjacent the powder charge, the surface of said wad facing the open end of the casing spaced from the open end of the casing, and means in said wad for igniting said powder charge,
  • a shell comprised of a tubular casing, one end of said casing being closed to form a breech closure, the opposite end of the casing being open, a powder charge in said casing adjacent the closed end, a wad in said casing adjacent said powder charge and spaced fromthe open end of the shell, said wad having a diameter substantially equal to the diameter of the casing, priming means located in the surface of the wad facing the open end of the casing for igniting said powder charge, and a flash tube in said wad between the priming means and powder charge.
  • a device of the character described including a plastic tubular casing, closed at one end and open at the opposite end, a propellant charge in said casing adjacent the closed end, a plastic wad in said casing with an interference fit disposed from the open end of said casing adjacent said powder charge, and means in the surface of said wad facing the open end of the casing for igniting said charge.
  • a device of the character described including a tubular casing comprised of a thermoplastic material, closed at one end to form a breech closure and open at the other end, a propellant charge in said casing, a wad of thermoplastic material disposed in said casing with an interference fit, said wad being adjacent to said propellant charge and spaced from the open end of the casing, primer means in said wad having its striking surface spaced from the open end of the casing, said wad adjacent the propellant charge is concave to form a gas sealing means.
