Definitions

  • the present invention relates to a cartridge, and more particularly, to a cartridge ignited by heat sensitive means.
  • the present invention is predicated on the task to create an ignition mechanism which is considerably more insensitive compared to the known mechanical or electrical ignition mechanisms, yet is very reliable in operation.
  • the cartridge essentially consists of a metallic headpiece with good thermal con ductivity properties within which is disposed a heat sensitive primer composition, and of a case made of a material wit-h poor thermal conductivity properties which contains the propellent means.
  • Another object of the present invention resides in the provision of an ignition mechanism for cartridges which is less sensitive than the known prior art devices yet is extremely reliable in operation and less prone to failure.
  • a further object of the present invention resides in the provision of an ignition mechanism for cartridges operable by heat which can be readily and accurately controlled.
  • a still further object of the present invention resides in the provision of a cartridge provided with an ignition device so constructed and arranged as to permit simple assembly of the parts.
  • FIGURE 1 is a partial cross sectional view through a first embodiment of a cartridge in accordance with the present invention in which the case is placed over a reduced cross sectional portion of the bottom.
  • FIGURE 2 is a partial cross sectional view through a modified embodiment of a cartridge in accordance with the present invention in which the case is embedded in a groove provided in the bottom, and
  • FIGURE 3 is a partial cross sectional view through still another modified embodiment of the cartridge in accordance with the present invention in which the bottom is embedded in the case.
  • reference numeral 1 designates in all embodiments the headpiece of the cartridge which consists of a material having high thermal conductivity such as, for example, copper, aluminum, etc.
  • the heat sensitive ignition or primer composition 2 is disposed in a recess 2a of the headpiece 1.
  • the ignition or primer composition 2 is separated by a cover 11 from the propellent States Patent "ice means 3, the charge, properly speaking of the cartridge.
  • the propellent means 3 is disposed in a cartridge case 4 made of a material with poor thermal conductivity, such as iron or plastic material, particularly of a readily destructible plastic material of any known type.
  • the propellent means 3 itself consists, for example, of a smoke-free loose single-base or double-base powder.
  • the cartridge is inserted into a magazine or cartridge support 7.
  • FIGURES 1, 2 and 3 illustrate three possible realizations of the connection of headpiece 1 and case 4.
  • FIGURE 1 the headpiece 1 passes over into a neck portion 8 of reduced cross section.
  • the case 4 is placed or slipped over this reduced cross sectional portion 8. The securing of the case 4 at the neck portion 8 takes place by the bead 5.
  • the headpiece 1 is provided, in addition to the neck portion 8, with a groove 9 into which is inserted the case 4.
  • the securing takes place in that the outer rim of the headpiece 1 is indented or notched and a ridge or rabbet is formed thereby which secures the case 4.
  • FIGURE 3 shows a connection of headpiece 1 and case 4 in which the neck portion 8 of the headpiece 1 is received within the case 4 and is completely surrounded by the same along the outer rim 10 thereof.
  • the heat conduction from the headpiece 1 to the cartridge support 7 is at a minimum.
  • a cartridge for driving shells, securing bolts, tools, and the like comprising:
  • a metallic headpiece made of a material having good thermal conductivity
  • casing means having an open end and a closed end, said casing containing a propellent means and said open end secured to said headpiece, said casing means being made of a material having poor thermal conductivity,
  • said headpiece being provided with a groove-shaped recess, said casing means open end being inserted into said recess and being secured to said headpiece by an indentation in said headpiece.
  • a cartridge comprising a main explosive charge; a gene-rally tubular cartridge case means having a closed end and an open end containing said main explosive charge in its interior; headpiece means constructed of a relatively thick material having good thermal conductivity, said headpiece means having securing means operatively secured to said open end of said cartridge case means, said headpiece means having a recess opening into the interior of said cartridge case means; a relatively highly heat sensitive primer explosive charge within said recess in good thermal conductive relationship over a substantial portion of its exterior area with said headpiece means; said headpiece means being operable to substantially isolate said heat sensitive charge from exterior mechanical stress and being operable to readily conduct exteriorly applied heat to said heat sensitive charge for igniting said heat sensitive charge.
  • said headpiece means has an inwardly extending reduced diameter neck portion forming said recess, and wherein said cartridge case means encompasses and is attached to said neck portion operatively to thermal-1y insulate said neck portion.
  • said cartridge case means is constructed of a combustible material that burns with the main explosive charge and boosts the energy of the main charge.
  • said headpiece means has an inwardly extending reduced diameter neck portion forming said recess, and wherein said cartridge case means encompasses and is attached to said neck portion operatively to thermally insulate said neck portion.
  • said cartridge case means is constructed of a combustible material that burns with the main explosive charge and boosts the energy of the main charge.
  • said headpiece means has an outer rim of greater diameter than said neck portion and wherein said cartridge case means encompasses said outer rim operatively to thermally insulate said headpiece.
  • said cart-ridge case means is constructed of a combustible material that burns with the main explosive charge and boosts the energy of the main charge.
  • said cartridge case means is constructed of a combustible material that burns with the main explosive charge and boosts the energy of the main charge.
  • said cartridge case means is constructed of a combustible material that burns with the main explosive charge and boosts the energy of the main charge.
