Definitions

  • the main object of my invention is to provide a system of the above mentioned kind which is better adapted to meet the requirements of practice than those used up to the present time.
  • the essential feature of my invention consists in interposing, between the gun and the support of such a system, gas operated meansfor urging the gun in the recoil direction -with respect to the support, during the recoil movementof the gun, said last mentioned means being fed with gas through tap means provided in the gun barrel' so as to supply powder gases to said. means every time arshot-is -iired by the gun.
  • FIG. l is a diagrammatic elevational view with parts cut away of a gun system constituted by a small bore automatic gun mounted in an aircraft wing, this system being made according to my invention.
  • Figs. 2 and 3 are sectional views on an enlarged scale showing details of said gun system.
  • the gun proper and the means for fixing it to the aircraft wing are devised in any suitable manner such that the tiring cycle of the gun is quite independent of its recoil cycle.
  • the gun system comprises a gun 1 having a movable breech-block 2 slidable in a breech case 3, this breechblock, which is urged frontwardly by a recuperator spring 4, being adapted to meet, at the end of its recoil stroke, a spring 5 acting as a shock-absoring and accelerating element capable, every time a shot has been fired, of
  • Said breech-block 2 is locked, every time a shot is tired,
  • rIhis gun is supported at the front by a wing framework element 6 through a ball and socket device including alball 7 in which the gun can slide, every time a shot is fired, under the effect of recoil, against the action of a return spring 8.
  • the rgun is supported by an arm 9 hinged, at its ends, respectively to the gun and to anelementof the wing framework.
  • a feed mechanism 10 is provided for feeding cartridges to the gun.
  • This feed mechanism does not participate in the recoil movement but is connected on the one hand, in a. sliding fashion, with the gun, and on the other hand, for instance-through a link 11, to a fixed point of the wing framework, for instance to element 6 thereof.
  • the operation of the feed mechanism is obtained as a result of the relative displacements taking place between the gun and this mechanism.
  • a finger 12 carried by the gun-comes, on every recoil stroke of the gun ⁇ to lift a roller 13 the displacements of which serve to wind up the spring which operates the feed mechanism.
  • gun barrel carries a'p-iston '14 movable in a cylinder 15 rigid with ball element 7.
  • a gas tap 16 provided in the wall of the ⁇ gun barrel, feeds powder gases into said cylinder 15 when the projectile shot by the gun has moved past said gas tap, whereby the whole of the gun is urged rearwardly with respect to the wing framework element 6.
  • This shock normally tends to slow down the frontward return movement of the gun and might even, in some cases, start back into rearward direction the gun that is returning frontwardly. It will be understood that the higher the force that produces the frontward return movement of the gun, the more reduced is the perturbing action of the shock of the breech-block against spring 5 at the end of the rearward stroke of said breech-block.
  • the device according to my invention is already very interesting even if the recoil of the gun does not control the operation thereof.
  • the gun system above ⁇ describedturther includes a shockaa'bsorbing Vsys-tem. jSuch a system may be constituted for instance by a plurality of elementary shock-absorbers interposed between gun 1 and ⁇ its support, for instance (as shown .by Fig.
  • shock-absorbers may be made of any suitable construction, preferably such that they ⁇ do not brake the recoil stroke but slow down at least the endof rthe frontward return movement of the gun.- For instance,
  • each of them consists of an oil iilled cylinder 19 in which moves a piston 20 provided Y with at least one check valve 21 producing a braking action during the return frontward movement of the gun.
  • a gun system comprising, a fixedv support, Va gun .2,920,636 l l f movable for recoil and counterrecoil with respect to said support, resilient means between said gun and said support for urging said gun to a xed battery position with respect to said support, supplementary recoil impulse means including a cylinder mounted in said support and fixed with respect thereto and a piston rigid with the gun barrel and slidable within said cylinder with Va gas tap connecting the inside of the gun barrel with the cylinder whereby 'gases passing into said cylinder act against said piston to impart a supplementary recoil impulse to thegun, cartridge -feecl mechanism mounted in a fixed position with respect to ⁇ said support, cooperating means carriedby said.
