Definitions

  • This invention pertains to the field of ordnance. More particularly, it describes a cartridge casing and process for manufacturing the same which is directed towards cartridge casings typically used in small and artillery caliber ammunition.
  • Cartridge casings used in small caliber to artillery caliber weapons provide the function of containing the other major components of the cartridge, including propellant, projectile or bullet and primer.
  • the casing In addition to being a container, the casing must expand slightly and act as a seal to prevent gases, generated by the piopellant, from leaking from, the forward or mouth end of the casing, along the sidewall of the casing, and through the breach or bolt face at the rear of the casing.
  • the head end of the casing must also absorb the striking force of the firing pin without deforming excessively.
  • a portion of the head end typically will extend beyond the support of the chamber wall of the weapon barrel. This is to provide access by an extractor mechanism on the weapon bolt to engage with an extractor groove formed in the sidewall of the casing of the rimless ammunition.
  • Multipart casings having an all-plastic sidewall have also been tried. Under the greater temperatures and more severe physical environments experienced in military weapons these designs have shown a propensity to fail at the joint of the plastic- to-metal base, causing jammed or damaged weapons. All-plastic cases have also not been shown to be as capable of sustaining the high pressures experienced in small caliber cartridges. Some applications have been successful, e.g. low pressure blank/training ammunition, but in general, success has not been achieved with higher pressure, conventional, ball/tracer ammunition.
  • US Patent 1,082,975 describes a cartridge casing with a simplified construction and reduced cost. It describes a center fire cartridge comprising an outer shell that extends continuously from the cylindrical to base-end portions of the casing, and an internal base cup. This cartridge is intended to operate on the basis of a Burdan-style primer.
  • the internal base cup which is "formed of a single piece of metal", is in the form of a thin, conically shaped plate that is, effectively, pleated.
  • This base cup is positioned internally at the base of the cartridge casing at its head end and is held in position along its outer circumferential edge by an "inwardly extending circular rib rolled in the shell.”
  • the primer is held in place by the internal base cup: "the metal of the base cup is bent inwardly to form a circular pocket which receives the primer...
  • At the bottom of the primeF pocket are holes 17 through which the flame of an exploded primer passes to ignite the power charge in the shell.”
  • This '975 patent provides a simplified cartridge construction- having a single outer member and a one-piece internal base cup.
  • the base cup is not of a design to assist the outer shell in resisting gas pressures in the vicinity of the head end particularly when exposed to the high pressures associated with modern propellants.
  • US Patent 933,030 describes a center fire cartridge which comprises The casing with a cylindrical sidewall fitted into a base cup at the head end of the casing.
  • the base cup includes a pocket for the primer of the Boxer type.
  • the casing sidewall is fitted within a round rim at the point where it engages with the base cup.
  • An outer, secondary head-end cup with an extended sleeve embraces both the base cup and the casing sidewall.
  • the sleeve portion of the secondary cup extends along the casing sidewall, extending partially towards the forward end of the casing. Pressed paper surrounds the primer pocket on the inner side of the casing, extending to the inner surface of the casing sidewall.
  • the '030 patent ostensibly provides a cartridge that is not substantially reinforced or protected from propellant gas pressure at its base end because of the low structural strength of the paper filler.
  • One object of the invention is to provide a cartridge casing for either rimmed or rimless ammunition with an outer casing wall that is protected or reinforced within the interior of the base or head end of the casing in order to resist the high pressures of propellant gases in the locations where the casing wall isn't supported completely on the outside of the casing by the weapon chamber and bolt interface.
  • the casing for ammunition in the form of a cartridge having a head end and containing propellant in its interior for use in small caliber and artillery caliber weapons comprises:
  • an inner reinforcing plug preferably seated against the head end to provide support to the casing against the high pressures experienced in the firing of the ammunition, the inner plug having a primer well recess formed therein and aligned with said end panel opening to receive a primer, the recess terminating in one or more perforations through the inner plug to permit gas from the primer to enter into the interior of the casing
  • the inner plug extends laterally between the primer well recess and the casing sidewall whereat the plug is provided with an outwardly-directed cylindrical plug sraface fitted to bear against the inner surface of the casing sidewall to seal-off the casing sidewall and casing end panel from propellant gas arising upon firing of the ammunition.
  • said outwardly-directed cylindrical plug surface extends forwardly towards the open end of the casing, past the depth of the primer well recess.
  • the inner plug is a solid body which extends laterally between the primer well recess and the casing sidewall where the plug is fitted to bear against the inner surface of the casing sidewall to seal-off the casing sidewall and casing end panel from propellant gas arising up on firing of the ammunition.
  • the inner plug may be in the form of a layer which conforms to the sidewall of the primer well recess, the interface of the end panel, and an initial portion of the inner surface of the casing sidewall to seal-off the casing sidewall and casing and panel from propellant gas arising upon firing of the ammunition.
  • the casing end panel is joined seamlessly in a unitary manner to the casing sidewall around the circumferential boundary of the casing end. That is, the sleeve or sidewall portion of the casing and the casing end panel are preferably "integrally formed".
  • the expression “integrally formed” indicates that there is continuity of material between the casing sidewall and the circular casing end panel.
  • the outer casing sidewall and outer casing end panel are all formed from one piece of material.
  • the thickness of the casing sidewall maybe equal to or greater than the thickness of the casing and wall panel, which is converse to the configuration of most standard ammunition. This feature conveniently integrates with the metal forming procedure described further below.
  • the inner plug engages with the inner surface of the casing sidewall through an interference fit.
  • One advantage of the interference fit e.g. having a sealing, preferably voidless, contact between the inside surface of the outer casing sidewall and the outside surface of the plug, is to prevent propellant gas on firing from having access to the head end
  • Another advantage of providing such a coupling between the plug and casing sidewall is that it will help ensure that both parts are extracted as a unit from the chamber after firing.
  • the casing sidewall may be given a slight inward taper towards its forward end, forward of the plug, after the plug is fitted in place.
  • an inwardly protruding ring may be formed into the casing sidewall above the upper boundary of the plug to prevent shifting of the plug.
  • the casing end panel has a centrally located end panel opening and the inner plug provides the recess to receive a primer.
  • the casing end panel is provided with an inwardly depressed, cup-shaped primer pocket or well formed therein to accept a primer, This is an alternative to having the inner plug define the primer recess.
  • the primer well when formed integrally with the casing end panel includes a cylindrical sidewall provided by/connected to the casing end panel at the head end.
  • Such a primer well preferably also includes a seating surface for the primer in the form of an annular base that closes-oEfthe inner end of the cylindrical wall of the primer well, (except for a perforation therethrough to allow the primer gases to ignite propellant within the inner volume of the casing upon firing).
  • This seating surface for the primer is also preferably an integral extension of the casing end panel.
  • the plug is primarily seated against the inside surface of the end panel of the casing.
  • the plug in this latter variant is preferably shaped to overlie at least a portion of the inner side of the primer seating surface formed at the base of the primer well where it may optionally be further seated.
  • the primer gas perforations in the inner plug are aligned or are in communication with the perforation in the primer well seating surface to allow for the passage of propellant gases.
  • the plug may be partly supported by such wall as well as by the base of the primer well.
  • the primary support for the plug is provided by the fact the plug extends to contact securely against the inside surface of the head end of the casing.
  • the plug When the casing end panel extends inwardly to form the cylindrical sidewall of the primer well, it is advantageous for the plug to embrace this cylindrical sidewall of the primer well around its outside surface. This will strengthen the primer well against expansion when the primer is pressed therein, helping to retain the primer in the primer well by the friction fit.
  • the casing sidewall in the variant of rimmed ammunition the casing sidewall, at its juncture with the circumferential boundary of the end • panel, extends outwardly to provide that the diameter of the end panel is greater than the diameter of the cylinder defined by the casing sidewall.
  • the inner plug does not conform to the casing sidewall in the region of the annular rim. [Uv24 !
  • the casing sidewall has an extractor groove formed therein adjacent to the head end.
  • the inner plug may itself have an annular groove, step or recess formed therein and the casing wall overlying the groove, step or recess in the plug may be deformed to fit within such space to provide an extraction groove for the casing.
  • the fit between the casing wall within the groove and the inner plug need not be intimate, which is to say that the casing wall and the inner plug do not necessarily need to be in complete, sealing contact along the entire outer surface of the inner plug.
  • the plug may have a straight-footed cylindrical support that extends to the inside surface of the end panel at the head end of the casing.
  • the diameter of this cylindrical foot may be reduced from the main diameter of the plug to provide room for the formation of the extraction groove in the sidewall of the casing.
  • the plug may also be made with its own rim at the head end portion of the cylindrical foot. Then the outer casing sidewall may be rolled or crimped over this plug-rim to lock it in place.
  • This configuration will have the advantage of allowing the rim-forming operation to provide a sharper radius on the forward corner of the outer edge of the casing rim, stiffening the rim and providing a preferred shape to better engage with the extractor mechanism of the weapon.
  • the cartridge rim can be bent slightly forwardly so that it protrudes at less than a right angle from the casing sidewall.
  • the thickness of the casing sidewall maybe equal to or greater than the thickness of the casing and wall panel.
  • the outer casing sidewall and end panel can be made of nearly the same relatively constant thickness. Either result can conveniently be obtained by forming the side and end walls from a single piece of material which initially has a thickness which is near or equal to that of the final thickness of the end panel. Starting with a thinner sheet of material, particularly a metal, allows formation of the cylindrical sidewall of the casing by progressive stamping operations that are not interrupted by as many annealing and lubrication treatment steps as would be required if a thicker sheet of material were used initially. This process is to be distinguished from the traditional casing forming operation in which a thick sheet of the initial material is used to form a thick head end and the thinner casing sidewall is re-formed out of the annular material around the head end.
  • Materials which may be used for the outer cylindrical sidewall and end panel of the casing in accordance with the invention include stainless steel, steel (preferably pre- coated carbon steel to provide corrosion resistance), brass or brass-type alloys, aluminum and hardened or tougher forms of aluminum alloys, and equivalent suitable polymeric plastic materials.
  • appropriate materials include aluminum, brass, steel, stainless steel, and appropriate polymeric plastic materials.
  • the use of stainless steel or a precoated carbon steel should reduce the need for a final coating on the case.
  • Use of precoated steel may be able to reduce the number of operations and cost by applying the coating to the rolled steel strip in a continuous process before any forming operations are begun.
  • Such coated strip is commonly used for shot shell bases, lamp parts, etc. to reduce costs and provide the appearance of brass.
  • the plug may not necessarily need to be a fully solid body which extends between the primer recess and the casing sidewall (where it is fitted to bear against the inner surface of the casing side wall). Instead, it may be in the form of a sheet shaped to fit over and embrace the primer well, extending to and along the inside surface of the casing end panel at the head end, and extending upwardly along the casing sidewall in the form of an outer a cylindrical extension to this sheet.
  • An inner plug according to this design is intended to provide a combined thickness in the casing sidewall and the base area of the casing at the head end as well as well as a sealing effect sufficient to withstand and seal-off the outer surface of the casing at its head end frompropellant gas pressure!
  • This outer cylindrical extension to the plug may be in the form of a flange that is positioned to extend upwardly towards the open end of the casing while lying against the inner surface of the casing sidewall.
  • this outer cylindrical extension extends forwardly of the depth of the primer well or recess.
  • this solid body may have its own forwardly directed cylindrical extension in the form of a cylindrical sleeve or flange that lies sealingly against the casing.
  • the material forming such a flange is preferably of a dimension and sufficiently ductile to improve the seal between the plug and the casing sidewall under the pressure of expanding propellant gases. To provide this function, it may taper with reducing thickness as it extends towards the forward end of the casing.
  • a rimmed metal base cup initially formed from a thin coin in the manner similar to that disclosed in US Patent 2,193,245 by Buxton but preferably being thinner than normal, is re-formed to provide the outer sidewall of the casing, with the base panel at the head end of the casing.
  • the inner plug having provision for an extractor groove in the form of a plug groove or annular indentation formed in the lower portion of its outer circumference sidewall, is then pressed- in or inserted into the base portion of the casing sidewall. Then the outer casing is crimped or deformed into the plug groove to provide an appropriately shaped extractor groove for the casing.
  • a rimless casing according to the invention may be similarly manufactured by progressively forming from a sheet-metal sheet a cylindrical precursor to the cylindrical portion of the casing, closed-off the cylindrical precursor at the head end by an end panel. At the circumferentially boundary between the end panel and the cylindrical wall of the precursor casing, an outwardly protruding rim is formed in the normal manner for forming a rim on rimmed ammunition. Thereafter, the precursor casing is expanded to its normal, foil, diameter in the region above the location of the extraction groove which is to be present in the final rimless cartridge. Then the plug in accordance with the invention may be inserted into the bottom of the casing.
  • the unexpended portion of the material of the casing sidewall - defines the extraction groove.
  • This is the reverse process from that of providing an initial casing with a foil diameter sidewall and then deforming the sidewall inwardly to form the extraction groove.
  • a rim type casing is needed, as an alternative to forming the rim before insertion of the inner plug, such a plug of appropriate final diameter, preferably having its own rim which will ensure centering, can be inserted into the casing.
  • the casing outer wall is then deformed at the head end to form the protruding rim by reducing the diameter of the casing above the rim present on the plug.
  • the casing sidewall is reduced to an inside diameter which is able to mate intimately with that of the outer wall of the plug.
  • the outer casing layer may then be rolled over this plug rim. This configuration of the invention helps ensure that the plug is locked into place inside the cartridge casing.
  • the outer surface of the casing is made entirely of polymeric plastic which is molded to extend continuously along the cylindrical sidewall sleeve portion of the casing and around the head end to form the end panel and embrace the cylindrical inner plug.
  • This outer surface may be extended to define a primer well in the head end.
  • This is the reverse of conventional practice, e.g. as in shot shells, wherein the plastic sidewall is molded integrally around only the outer periphery of the metal cup forming the head end of conventional shotshells. This avoids the need fo ⁇ a junction for the joining of plastic and metal components at the sidewall, which has been a failure point in prior configurations.
  • polymeric materials such as nylon derivatives, VECTRATM, or other equivalent materials can be used as the ' polymeric plastic material.
  • the inner plug provides protection for the polymeric plastic outer surface of the casing at its head end against the effects of propellant gases.

  • the inner reinforcing plug 10 is typically fabricated using common crafting practice, by casting, molding, or cold heading. This reinforcing plug 10 is preferably of a stronger material than the outer case member 2, such as steel, or certain plastics. It may also be made aluminum, in which case the outer case member 2 would provide protection from the "burn-through" often experienced with all-aluminum cases.

  • the plastic outer casing 16 maybe molded around the inner plug 7, which may be metallic, to provide increased strength in the head or base area of the cartridge 1, which is hard to achieve with lower strength plastics. Molding around the higher strength plug eliminates the need for a joint of the two materials and obviates the potential failure point at the juncture, which is common in prior art.
