Fir-ma Rheinrnetall G.n1.b.H., Dusseldorf, Germany Filed Dec. 3, 1962, Ser, No. 241,875 I Ciaimspriority, application Germany Dec. 5, 1961 g p 3 Claims. (Cl. 89-46) a The invention relates to the installation and mounting v of a'rnachine gun or similar weapon, mounted movably' in'recoil, but otherwise rigidly in turrets,

M d for example in the rotating turrets of armoured cars.

lnarmoured vehicles it is frequently desirable to fit, in addition to the gun, also a rigidly fixed machine gun to provide sufiicient firing power also for shorter distances.-

Howeverythis machine gun must be fixed so that it may recoil and the mounting should be gas-tight, that is to say,

I v 'tightagainst'powder smoke and gases, whilst allowing at i the ametime a wide range of vertical and lateraladjust ment. In addition, installation and dismantling should be possible quickly and;easily..

In a knownmounting for a machinegun, the barrel is locatedat the muzzle end longitudinally displaceably in a sleeve which-expands conically towards'the outside, and which is mounted in turn by .means of a screwed sleeve e and asp herical annulus. 1 as -forward pivot bearing and is located in turn in the Wall offthe. turretby means of special divided sleeves, adapted in shapeto the spherical configuration. The machine gun housing isnot, however, movable inrecoil. v j Tl 1e,manufacture of associated spherical surfaces and ,counter-supports is" rather expensive; furthermore, also This spherical annulusserves In the revolving turret 1 of an'armoured vehicle is mounted the vertically pivotable shield 2 for the gun-barrel (not shown) and for a'machiue gun. To provide protection against enemy fire, theshield has an outside screen 3. The machine gun has within the zone of the muzzle a recoil booster 5, connected by a thread with the housing,

and carrying on its rear end an annular shoulder 6 with. spherically shaped circumference. This annular shoulderf 6 is located longitudinally 'displaceably in a cylindrical bore 7 of the screen; in'this way the muzzle of the weapon is articulatedly and also. longitudinally displaceably lo cated in the screen. Apart from that, the machine gun is mounted longitudinally displaceably in a slide 8 in order to absorb the recoil movements;jthe'slide 8 is connected with the carriage base 9. Slide 3 and base 9 from the mounting which is equipped with an adjusting device in order to adjust the machinegun' in heightand laterally. This mountingis fixed by means of boltsfll, located in oblong holes Iii, to the cradle 12 of the gun barrel (not shown). After unscrewing these bolts, the mounting maybe adjusted by means of anadjusting screw 13, resting against a pin' 14 mounted on the cradle, so as to provide adjustment in height, whilst the entire-mounting with the rear end of the machine gun may 'swivel in thevertical plane 1 upwardly and downwardly about the annular shoulder.

1 by means of which the slide ismounted to the mounting the mounting and dismantling of the weapon become very hiring tolerances results in inaccuracies, and the presence Ilation of the weaponmay befulfilledin that the pivot b ore in-the; wall of the turret. or thei gun shieldflectedjowards the front.

In addition, with a plurality of components, ar-' ranged-Ione withintheother, summation of the manufacofa'plurality of sliding, mutually movable parts leads to H invention, these drawbacks maybe i avoided, and the requirements made regarding the instalbearing or mounting forms a part of the recoil booster or the'ilike, and-has the shape' of anjexternally sphericalan p nularshoulder'surrounding the same, and mounted uni- 45 i ve rsall y movably'and axially displaceably'in acylindric'al',
