Definitions

  • the requirements to be met by a truly satisfactory antitank gun for use by infantry are very exacting.
  • the gun must fire a projectile of substantial size, for example over 3 /2 lbs., yet the gun should if possible be sufficiently light to be carried by one man, and arranged to be fired from the shoulder by a prone manthat is to say it should not require a free-standing mounting.
  • the muzzle energy required is substantial, and yet recoil on the firer must, at least to a large degree, be avoided. Attempts have been made to achieve this by discharging rearwards from the gun either gas, or small shot, or a counter projectile.
  • the Burney gun proposed in about 1942, but never to my knowledge used practically, had a rear barrel inclined at an obtuse angle to a front barrel, the rear barrel terminating in a set of nozzles for discharge of gas. This would in no way reduce the dangerous flash. In fact the inclination of the rear barrel was proposed solely to enable the front barrel to be elevated without the rear barrel striking the ground.
  • a gun which can be loaded with a unitary round including a front projectile, a propellant charge, and a rear quantity of small shot, and which will discharge the small shot in a direction at an obtuse angle, of the order of 150, to a front barrel.
  • a very small amount e.g. 0.040 inch in a twelve bore gun
  • the gun With a flat trajectory, the gun is fired with the front barrel nearly horizontal, and consequently the shot is discharged obliquely upwards and rearwards at about 30 to the ground. It follows a curved trajectory upwards and then downwards, and encounters such great air resistance that it disperses and reaches the ground at non-lethal velocity. Consequently there is only a very small area immediately in rear of the gun that is dangerous to friendly troops.
  • the two gas checks may be connected by a tie so that on firing there is confinement of the charge until the tie is broken by a substantial rise in gas pressure.
  • FIGURE 1 is a longitudinal section of the gun, loaded with a round
  • FIGURE 2 is a longitudinal section of part of the gun and round on a larger scale.
  • the gun includes a straight front barrel 2 and chamber 4 in one piece, the bore of the chamber being slightly greater than that of the front barrel, together with a rear barrel 6 which is curved in the part of its length nearest the chamber, through an arc of about 30, and possibly stiffened by a web 7.
  • the rear barrel is supported by a leg 8 and a foot 10, and is steadied and aimed by a prone man by means of a shoulder piece 12 and a handle 14.
  • the outer straight ends 15 and 17 of the front and rear barrels can be unscrewed to reduce the bulk of the gun for carriage.
  • the projectile 1 consists of a head 16, tubular tail 18, and drum or cuff type stabilizer 20 on the end of the tail, and is driven by a gas check 22 having a spigot 24 which fits into the tail and which is jettisoned by a small charge 23 after the projectile leaves the gun.
  • a safety collar 25 is in fact removed before loading.
  • a quantity of small shot 26 is housed in a thin metal casing 28, which carries the second gas chesk 30.
  • the centres of the gas checks are connected by a perforated brass tube 32 which acts as the frangible tie and which houses an electrically-fired primer 38.
  • the main charge (which is omitted from FIGURE 2 for clarity) lies in the space 36 around the tube.
  • the tube 32 can readily be made to exert a substantial degree of confinement to a good degree of accuracy. Moreover the breaking strength of the tube can easily be adjusted by varying the size of the perforations. Consequently a good level of uniformity may be obtained in the behaviour of successive rounds, which means that once the sights of the gun are set it will hit a target accurately.
  • the casing 28 has a rear cover 29 lightly soldered on, and includes a parachute 31 which is separated from the small shot 26 by a wad 33 and is connected to the front of the casing by a rod 35.
  • the casing bursts to release the small shot and is itself lowered harmlessly by the parachute.
  • the casing may disintegrate. The shot is not only retarded by air resistance, but also somewhat dispersed.
  • One lead 38 from the primer goes to the tube 32 and is thus connected, by contact of metallic parts, to the barrel of the gun, While the other lead 40 goes to a contact ring 42 of metal foil mounted on a ring 44 of insulating material which fills a gap between the rims of the gas checks. These rings disintegrate or are burnt away on firing.
  • the contact ring engages a plunger 46 which extends through an insulating bush 48 in the Wall of the chamber.
  • the plunger and barrel are connected to a magneto operated by squeezing a front part 50 of the handle 14.
  • the disintegration of the rings 42 and 44 means that there is nothing to be extracted from the gun after firing. That is to say, the round is devoid of anything in the nature of a cartridge case.
  • the chamber and front barrel can be disconnected from the rear barrel while remaining supported in a ring 51 carried by arms 52 and 54 of a bracket extending forwards from the rear barrel.
  • the rear of the chamber has an external interrupted thread 58 in a socket 59 on the forward end of the rear barrel. Just in front of the thread the socket is enlarged and houses a U-sectioned flexible brass sealing ring 60, and a rigid guide ring 62. These cooperate with a cylindrical surface 64 on the chamber.
  • the front barrel and chamber In loading, the front barrel and chamber, on being released from the socket by a quarter turn, are slid forwards in the ring 51 until the rear end of the chamber is clear of the socket, and then swung about pins 66 until the rear end of the chamber is sulficiently offset from the socket to permit a round to be inserted. The movements are then reversed and the gun is ready to fire.
  • a contact 68 on an insulated mounting on the arm 54, makes con- ,tact with the outer end of the plunger 46 in the wall of the chamber when the front barrel and chamber are fully screwed home, thus completing the firing circuit from the l magneto.
  • the plunger 46 is urged outwards by a light spring 70, so that it does not obstruct the barrel during loading.
  • the contact 68 is urged inwards by a stronger spring 72 which urges the plunger inwards against the contact ring 42.
  • the projectile by reason of its favourable shape for air flow and its tail stabilizer, does not need a high velocity, but will travel in a nearly flat trajectory with a relatively head of a kneeling man. Consequently the sole danger in rear of the gun is to a man standing upright directly behind the gun within 2 or 3 yards of the rear muzzle.
  • the precise angle between the directions of discharge from the two barrels is not critical.
  • An obtuse angle in the range to 140 is convenient, but angles nearer or nearer 90 are both possible.
  • this invention is primarily concerned with anti-tank weapons, the same gun may be used to fire other projectiles for other purposes, for example anti-personnel projectiles.
  • the gun shown in the drawings is single-shot with hand loading, the invention may be embodied in guns with magazine loading and automatic firing.
  • a portable infantry gun comprising: a first tubular member defining an elongate, open-ended passage having a straight axis and forming chamber and front barrel portions of the gun; a second tubular member defining an elongate, open-ended rear barrel passage for the gun and having a curvilinear axis the two extremities of which are inclined to one another at an obtuse angle of the order of 150 to 140, the rear barrel passage having the same substantially uniform bore along its entire length; and means so detachably engaging the chamber portion of the first tubular member with the second tubular member as to join the passages with their axes in alignment at the joint and form a continuous open-ended tube within the gun; and a unitary round loaded within the chamber portion of the gun, the round comprising a projectile of large mass relative to the mass of the gun; a cup-shaped gas check on the rear end of the projectile adapted to seal the front barrel portion; a thin-walled casing containing a quantity of small shot and adapted to pass along
  • a portable infantry gun comprising: a first tubular member defining an elongate, open-ended passage having a straight axis and forming chamber and front barrel portions of the gun; a second subular member defining an elongate, open-ended rear barrel passage for the gun and having a curvilinear axis the two extremities of which are inclined to one another at an obtuse angle of the order of 150 to the rear barrel passage having the same
