Definitions

  • the safety device comprises a, plug or pin provided with a drawor pull-wire or the like and with a hole for the passage of the igniter, preferably of such a cross section as to hold the detonating cap by friction, and a cap'secured to the plug or pin, so that on pnlhng the wire the lug and thus also the cap are pulled out o the bore-hole, thereby pushing in front of it the tamping or stemming.
  • the cap comprises a, plug or pin provided with a drawor pull-wire or the like and with a hole for the passage of the igniter, preferably of such a cross section as to hold the detonating cap by friction, and a cap'secured to the plug or pin, so that on pnlhng the wire the lug and thus also the cap are pulled out o the bore-hole, thereby pushing in front of it the tamping or stemming.
  • the tamping is removed to the extent of the cross-sectional area of the plug when' pulling-out the latter it is possible to introduce, if desired, a fresh cartridge into the bore-hole and to repeat the shot.
  • the plug is furnished with a centrally dis posed bore 4, in which a cap 5 is secured with a tight fit.
  • a wire-hook 6, for removing the entire device from the,bore-hole, is attached to the plu 1 by means of its inwardly bent ends 7, an a long wire 8 is tied to the said wire-hook 6.
  • the ignition wire or fuse is connected to the cap in any convenient and known manner and passes through the bore 4 and out of the bore-hole into the open. In order to secure the i ition wine or fuse in the proper position t e same may be wound around the wire-hook 6.
  • the safety device is employed in' such a manner, that the upper end of the cartridge-casing is pushed over the reduced end 3 of the plug and is secured thereto by a string or the like which is embedded in the groove 2.
  • the cap On pulling the wire 8 the cartridge and at the same time also the cap are pulle out of the bore-hole.
  • blastmg cartridges which easily ex lode when subjected to friction, such as ynamite-eartridges in a frozen condition, the cartndge-easmg it not fixed to the plug, and when pullm the wire 8 the cap is pulled out of the cartridge, while the latter remains in the bore-hole and may-be'exploded for instance by a' cartridge pushed over the same.
  • a safety device for explosive cartridges comprising in combination a detonating cap, a plug provided with a longitud nally extending hole of such a cross section as to receive and hold the detonating cap by friction, and a pulling member attached to the plug.
  • a I safety device for explosive cartridges comprising in combination a detonating cap, a plug provided with a longitudinally extending hole of such a crosssectlon as to receive and hold the detonating cap by friction, the detonating cap partly extending into the hole of the plug and secured therein with a tight lit and a pullin member attached to the plu so that on pu ing the member the plug and also the detonating cap may be pulled out of the bore hole.
  • a safety device for explosive cartridges comprising in combination a detonatlng cap, a plug provided with a longitudinally extending hole of such a crosssection as to receive and hold the detonating cap by friction, a hook secured to the plug, a pulling member attached 'to the hook, the detonating cap partly extending into the hole of the plug and secured therein with a tight fit, so that on pulling the member the plug and also the detonating cap may be pulled out of the bore-hole.
  • a safety device for explosive cartridges comprising in combinatlon a plug provided with a reduced end for the attachment of the cartridge and with a longituplug, so that on pulling the member the plu and also the cap may be pulled out of like bore-hole.
  • a safety device for explosive cartridges comprising in combination a plug provided with a longitudinally extending hole and with a reduced end over which the cartridge-casing may be pushed, a groove provided on the said reduced end, a pulling member attached to the plug, and a cap secured to the said reduced end.
  • a safety device for explosive cartridges comprising in combination a-p1ug provided with a. longitudinally extending hole and with a reduced end over which the cartridge-casing may'be pushed, a hook se cured to the plug, a pulling member attached to the hook, a groove provided on the said reduced end, and acap secured to the said reduced end.
