Definitions

  • shot cartridge cases it is conventional in shot cartridge cases to provide, at one end of the case which is manufactured, for example, for cardboard or stain-hardened plastic, a twopiece fitting comprising an internal bottom plug, insert piece, or the like, of, for example, cardboard or plastic, and an external metal cap. These two sections are joined to the end of the case by radially compressing the metal cap by means of a suitable tool after the case and the bottom plug have been introduced therein, so that the case is held between the metal cap and the bottom plug by frictional contact.
  • the metal cap either additionally or by itself, with one or several indentations,corrugations, or the like extending in the circumferential direction, so that a shape-mating or form-locking connection is established between the metal cap and the case end.
  • This type of connection between the case end and the fitting however, has the substantial disadvantage that the manufacturing expenses are rather substantial in order to obtain a strength of the connection satisfying all requirements.
  • the underlying problems are solved in accordance with the present invention by connecting the two sections of the fitting in a shape-matting or form-locking manner, and by holding the end of the pipe, the casing, or the like, therebetween by means of shape-mating and/or frictional contact. If, in this connection, the shape-mating junction between the two sections of the fitting is constructed, for example, in the manner of a screw connection, it is possible to vary in a simple way the strength of the connection by threadingly engaging the two sections of the fitting to a greater or lesser extent.
  • the external section of the fitting annularly surrounds the internal section thereof and can be connected with the internal section in the manner of a snap connection.
  • one of the sections is made of a sufficiently elastic material.
  • connection can be still further improved by providing, according to a further suggestion of the present invention, at least one of the sections of the fitting, in the zone of theshape-mating and/or frictional connection, with fine .grooves, serrations, or the like extendingin theperipheral direction of the pipe, the casing, or the like. If both sections of the fitting are provided withsuch a surface shape, it is, of course, necessary to make sure that the grooves, serrations, or the like are arranged and constructed in both sections so that weakening or even severing of the material of the pipe, the casing, or the like is reliably avoided under all circumstances.
  • the above-described invention which can be employed, for example, for sealing one end of plastic casings, e.g., for blasting cartridges, can be used particularly advantageously in all cases where widely varying requirements must be met by the properties of the pipe, the casing, or the like, on the one hand, and the properties of the fitting, on the other hand, such as, for example, in the use as a shot cartridge case wherein the internal section of the fitting is formed with a primer support and an axial flash hole.
  • a tough and high-strength plastic e.g., strain-hardened low-pressure polyethylene
  • a plastic for example a polyamide or a polycarbonate.
  • FIG. 1 is a cross-sectional view of the individual components of the shot cartridge case prior to assembly
  • FIG. 2 is a cross-sectional view of the finished shot cartridge case.
  • the case 1 is made, for example, of strainhardened low-pressure polyethylene and is tapered at the end 2 into a truncated cone having a generating angle of about 45.
  • the internal section 3 of the fitting is inserted in the case 1, namely with the end having the annular head 6.
  • the internal section 3 is provided with an annular, cylindrical extension 7 serving for receiving the propellant charge and resulting in a reinforcement of the shot cartridge case and an improvement in the ignition and conversion of the propellant charge.
  • the internal section 3 is further provided with the bearing portion 8 for receiving the primer cap 9 and with the axial flash hole 10.
  • the section 3 is passed in the direction of arrow A with the annular bead 6 through the end 2 of the case 1, optionally with appropriately widening the latter elastically, and is pressed into the external, essentially annular section 4 of the fitting to such an extent until the annular bead 6, under corresponding elastic deformation of one or optionally also both sections of the fitting, snaps into the corresponding annular shoulder 11 formed in section 4.
  • This snap connection between sections 3 and 4 is constructed so that the end 2 of the case 1 is sufficiently firmly clamped between the sections 3 and 4 and is thus held securely by means of frictional contact and, when the material of the case 1 is sufficiently structurally rigid, also by means of shape-mating or form-locking connection.
  • the assembled shot cartridge is illustrated in FIG. 2, wherein the parts identical to those in FIG. I bear the same reference numerals.
  • the cartridge has propellant charge 12 within the annular cylindrical extension 7 of the section 3. This propellant charge is covered toward the front end 14 of the case by means of the interposed element 13 made, for example, of felt or cardboard, and resting on the extension 7.
  • the shot charge is disposed between element 13 and the front end 14 of the case, which is closed off, for example, by folding, in a conventional manner.
  • the primer cap 9 inserted in the support 8 presses the internal section 3 more or less strongly against the external section 4, depending on the dimensions of the primer cap as related to those of the support 8, and thus prevents an unintended detachment of the shape-mating and/or frictional connection of the pipe, the case 1 or the like with the fitting, even, for example, when one of the two sections of the fitting should be subjected to a minor plastic deformation during the assembly, which could entail, if the primer cap 9 were not inserted subsequently, under certain circumstances, an undersired reduction of the contact pressure between the two sections of the fitting. Furthermore, the pressure of the propellant gases forming after ignition is effective along the same lines, i.e., supporting the shape-mating and/or frictional connection.
  • a casing comprising a hollow elongated casing portion having an inwardly diverging open end portion with a passageway communicating with the hollow interior of the remainder of said casing portion, and a fitting means for securing said casing portion arranged at the open end portion of said casing portion, said fitting means including an internal section, at least a portion of which is constructed to abut the interior of said casing portion and another portion of which extends through the passageway in said open end portion, and a separate external section, at least a portion of which is constructed to abut the exterior of the open end portion of said casing portion and another portion of which abuts the portion of the inner section extending through the passageway, said internal and external sections having means for operatively joining said sections in the manner of a snap connection, at least one of said sections having at least an elastic portion constructed to be temporarily deformed in forming said snap connection and to spring back to a substantially undeformed state upon completion of the formation of said snap connection.
  • casing is a shot cartridge case, and the internal section is provided with primer cap support means and a substantially axial flash hole.
  • casing is a shot cartridge case, and the internal section is provided with primer cap support means and a substantially axial flash hole.
  • a shot cartridge casing comprising a hollow cylindrical casing portion having a substantially truncated conical end with a passageway communicating with the hollow interior of the remainder of said casing portion, and a fitting means for securing said casing portion arranged at the truncated conical end of said casing portion, said fitting means including an internal section having a ollow interior for receiving a primer cap and for providing an axial flash hole, a portion of the exterior of said internal section arranged in abutting relation to the interior of said casing portion and the remaining portion of the exterior of said internal section adapted to extend through the passageway in said truncated conical end of said casing portion, and an external section annularly surrounding and frictionally contacting said truncated conical end of said casing portion and the portion of said internal section extending therethrough, said internal and external sections being operatively joined in the manner of a snap connection, at least one of said sections having at least an elastic portion constructed to be temporarily deformed in forming said snap connection and to spring back
