Definitions

  • This invention relates to new and improved salvo projectiles of the class adapted for tiring from a squeeze or taper-bored rearm.
  • the objects of the invention are means by which a salvo of projectiles may be red from a single taper-bored barrel during each discharge, means by which the said projectiles are loaded into the firearm as a single assembly before discharge, means by which said projectiles mutually disassemble during shot travel and emerge separately from the barrel muzzle upon discharge, and means for achieving high velocity and a high order of accuracy and range in each of a salvo of projectiles tired during a single discharge.
  • Squeezebore guns are guns of known class in which the breech end of the bore is substantially larger in diameter than the muzzle end, the length of bore between breech and muzzle incorporating a taper which forces the diametral reduction of the projectile during shot travel.
  • Squeezebore guns of krown construction may be rifled or smoothbore, and the tapered portion of the bore may take one of several forms.
  • the form referred to in the following examples comprises a rifled cylindrical bore or full bore at the breech end, said bore merging into a smoothbore conical taper toward the muzzle, said taper terminating in a relatively short smooth-bore sub-caliber cylindrical bore adjacent to the muzzle.
  • the invention is applicable, however, to other forms of ried or smooth-bore squeezebore guns.
  • squeezebore ammunition projectiles of known construction usually comprise a sub-caliber projectile body having two annular skirts of substantially truncated conical form which are rigidly connected thereto, said skirts being adapted to lill the annular void between the sub-caliber projectile body and the full bore of the gun.
  • a forward and a rear skirt are employed, the forward skirt being primarily used for stabilizing the projectile against longitudinal instability in the form of pitching movements while same is in the barrel, the rear skirt being used for sealing the projectile in the barrel bore against escape of propellant gasses.
  • one or both skirts may be adapted to be engraved by the rifling and to receive the torque applied to the projectile thereby.
  • a cannelure is usually formed in the sub-caliber projectile body to the rear of the front skirt in known type squeezebore projectiles, said cannelure being adapted to receive the forward skirt during the nal phase of the squeezing operation so that a reasonably smooth exterior surface is provided for the projectile after it emerges from the barrel.
  • each projectile is an essembly comprising a plurality of axially disposed sub-projectiles adapted for salvo tiring.
  • Said sub-projectiles may be substantially similar or dissimilar, but according to the invention said sub-projectiles mutually cooperate and are rigidly interconnected before ring and usually during manufacture so as to enable the loading of the assembly as a single component into the breech of the firearm, the interconnecting means between adjacent sub-projectiles being adapted to rupture during the propulsion of the said assembly as itis propelled along the bore of the barrel.
  • Each sub-projectile of the assembly has a sub-caliber body having a diameter substantially equal to that of the sub-caliber bore at the muzzle end of the barrel so that said body substantially cooperates with said sub-caliber bore during its passage through same with negligible deformation.
  • Each sub-projectile of the assembly is also provided with a skirt usually of conical form which is rigidly connected to the rear of the said body, said skirt having a maximum diameter which usually slightly interferes with the full bore of the barrel in such manner as to form a gas seal within said bore and to engrave with respect to the rifling therein.
  • a simple skirt having the form of a substantially conical flare may be used.
  • a relexed skirt may be used within the a-mbit of the invention, in which the outer periphery of the skirt of each sub-projectile is provided with a rearwardly-extending cylindrical element, which, in the case of leading sub-projectiles in an assembly, is adapted to cooperate with the skirt of following sub-projectiles for the purpose of receiving a portion of the propulsive thrust, and which, in case of the rearmost sub-projectile in an assembly, is adapted to provide more obturating and engraving area with respect to the barrel bore.
  • each sub-projectile of said assembly is formed of a material and to such a contour as will enable said skirt to be inwardly deformed without rupture and without excessive absorbtion of energy during the passage of said sub-projectile down the tapered portion of the barrel until the maximum diameter of said skirt is so reduced as to substantially equal the diameter of the subcaliber body of said sub-projectile.
  • Each sub-projectile of a projectile assembly may be formed of a single homogeneous piece of material in which the forward portion of the body may be surface or otherwise hardened, or may alternatively be formed of a plurality of components rigidly connected together such as, for instance, a hardened core within the body of the sub-projectile having a jacket of relatively deformable material which is formed to flare outwardly to comprise the skirt.
  • the mutual cooperation of adjacent sub-projectiles of the projectile assembly according to the invention may be constructed by forming an axially disposed recess in the rear of the body of each leading sub-projectile said recess being adapted to receive the point of the body of the following sub-projectile, the cooperating area of the adjacent sub-projectiles being adapted to provide mutual support of said sub-projectiles against longitudinal instability.
  • the mutual cooperation of the reflexed skirt forms of sub-projectiles according to the invention may further comprise the contact of the rear annular face of each leading sub-projectile against a mating annulus in the forward face of each following sub-projectile of said assembly.
  • Adjacent sub-projectiles may be further interconnected according to the invention by the bonding together of the cooperating surfaces between adjacent sub-projectiles by means of a metallic or non-metallic material such as an alloy of lead or a plastic such as Teon, such material having the property of rupturing under heavy stress and providing a lubricating quality to assist in the relative separation of the formerly rigidly cooperating surfaces.
  • a metallic or non-metallic material such as an alloy of lead or a plastic such as Teon, such material having the property of rupturing under heavy stress and providing a lubricating quality to assist in the relative separation of the formerly rigidly cooperating surfaces.
  • the sub-projectiles of the projectile assembly according to the invention may be formed and assembled in such manner that an annular space is disposed between adjacent sub-projectiles. Said annular space may be fully enclosed between the skirts of adjacent sub-projectiles such as in the case of rearwardly reflexed skirts or said annular space may be enclosed between the forward and rear faces of adjacent following and leading sub-projectiles, respectively, and the bore of the barrel, such as in constructions having simple skirts.
  • Said annular space between adjacent sub-projectiles of a projectile assembly according to the invention may be left as an air void in which case the violent adiabatic compression of the air, due to the inward squeezing of the sub-projectile skirts which is performed during passage of the projectile assembly along the tapered portion of the barrel bore, is harnessed to force the separation of adjacent sub-projectiles.
  • each following sub-projectile may be provided with means such aS one or more gas passages or peripheral grooves which are adapted to be nipped closed -by the deformation of the skirt during the early phase of the squeeze operation, and via which a quantity of propellant gas may be bled into said space between adjacent sub-projectiles before the squeeze operation.
  • the said space between adjacent sub-projectiles may be lled or partly lled with a quantity of frangible or relatively soft material which is substantially incompressible but which ruptures or iiows under shock stress in such manner as will induce the separation of adjacent sub-projectiles during their propulsion along the tapered portion of the barrel.
  • the said space between adjacent sub-projectiles may be filled or partly filled with a quantity of solid or other propellant of known formulation which may be ignited during propulsion f the projectile assembly within the barrel bore by incandescent ash from the propulsive gasses and/ or by the heat of friction of the projectile assembly within the barrel bore and/ or by the compression ignition of air enclosed within the said space.
  • the forced separation of adjacent sub-projectiles of a projectile assembly may be performed by a combination of any of the above described means in accordance with the scale and particular requirements of each application performed within the scope of the invention, and in a manner as above described adapted to impart a substatial relative separating velocity between each adjacent sub-projectile.

  • FIGURE 5 is a similar section showing the same projectiles during the final squeeze, and while in the smoothbore sub-caliber portion of the barrel adjacent to the muzzle.
  • FIGURE 6 is a similar section of an assembly of squeezebore sub-projectiles of a form having reexed skirts.
  • the projectile assembly 1 comprises four individual sub-projectiles 2, 3, 4, and 5, each of which is substantially similar in form and each being formed from a single piece of material.
  • each of the said sub-projectiles for instance, sub-projectile 2 is provided with a body 6, the point 7 of which is flame hardened, and a deformable conical skirt 8.
  • Said skirt is formed to an enlarged diameter and provided with a cylindrically formed rim 9 adapted to lill and engrave in the rifled full bore 10 of the gun, said skirt having a hollow cavity 11 to its rear which is formed in conjunction with the thickness of the skirt 8 in such manner as to accommodate said skirt during the deformation of squeezing.
  • Each of said sub-projectiles is provided with an axially disposed recess 12 which is formed in the rear of the body thereof as shown in subprojectile 5. Said recess formed in each sub-projectile 2, 3, 4, 5 is adapted to closely cooperate with point 7 as shown in sub-projectile 1, of each adjacently disposed subprojectile in such manner as to prevent mutual longitudinal instability.
  • the cooperating areas of all adjacently disposed sub-projectiles are rigidly connected by means of a bond 13 of Teflon.
  • the annular space 14 included between the skirts of sub-projectile 4 and 5 according to this example is an air-filled void.
  • the skirt 15 of sub-projectile 5 is provided with a gas passage 16 which communicates between the ring chamber volume 17 and the space 14.
  • the annular space 18 included between sub-projectiles 3 and 4 is filled with a deformable plastic material 19 such as synthetic wax.
  • the annular space 20 disposed between sub-projectiles 2 and 3 is partly lled with a quantity of solid propellant 21 of known formulation.
  • FIGURES 3, 4 and 5 Upon the introduction and locking of the projectile assembly 1, a quantity of propellant (not shown) and an ignition means of known form (not shown) in the breech of the firearm, the sequence of operations of the projectile components within the barrel leading to the propulsion of the individual sub-projectiles from the muzzle of the barrel as a result of discharge, is described with reference to FIGURES 3, 4 and 5.
  • the projectile assembly 1 is propelled along full more 10 of the barrel.
  • the acceleration of said projectile assembly is relatively greater than that of projectiles of usual density with respect to bore area.
  • some of the propellant gasses are vented via passage 16 into space 14.
  • skirts 8 and 8 of sub-projectiles 2 and 3 respectively are inwardly deformed by their passage along the tapered bore 22 the violent compression of air locked in space 20 causes the compression ignition of propellant 21 thereby providing gas pressure which greatly assists in the separation of sub-projectiles 2 and 3.
  • each said sub-projectile has been reduced by inward deformation to have substantial density with respect to its area, has been imparted unusually high velocity, is stable owing to its high rate of spin, and is not influenced in its accuracy as in known forms of salvo ammunition by muzzle blast by reason 0f the sequential and symmetrical nature of the ejection of the salvo of projectiles and their propellant gasses.
  • any combination of the above devices for separating the several sub-projectiles in each projectile assembly may be used in each projectile assembly form.
  • spaces 14, 18 and 20 may all be filled or partly filled with a substantially incompressible, relatively lightweight deformable or frangible material.

  • constructions according to this example are usually preformed in firearm forms wherein there is a relatively large full bore to sub-caliber bore ratio. According to this example substantially more mechanical cooperation is made available between adjacent sub-projectiles of a projectile assembly thereby increasing their mutual support potentialities during propulsion within the gun, for the purpose of preventing deformation or rupture of the rearmost sub-projectile(s) in such firearm forms.
