Definitions

  • This invention relates to an ammunition guide for beltfed elevating guns in which the rounds are fed from a stationary magazine part vthrough a channel in a trunnion carried upon an elevating part of the gun.
  • the gun itself should be visualized as being of conventional design having a gun barrel which can bef'elevated or depressed by means of trunnions journalled in a gun mountl and is fed from a magazine.
  • Another object of the present invention is to provide an ammunition guide for elevating guns of the type described in which a trunnion integral with the elevated mass of the gun is provided with a passageway through which an ammunition belt is fed and which orientates the ammunition carried thereby into the direction for ramming into the breech of the gun in any position of the elevational mass of the gun relative to the stationary magazine thereof.
  • a trunnion carried by the elevating mass of the gun is provided with a channel or passageway extending longitudinally therethrough that is defined by walls formed by generatrices having a direction approximately parallel with the elevation axis, which generatrices on the side of the trunnion directed toward the elevating mass of the gun follow an yoblong groove, which passageway allows the vpassage of rounds therethrough only when the longitudinal axes of such rounds are parallel with the ramming direction of the gun.
  • generatrices on the external side of the trunnion adjacent to the stationary magazine of the gun following a recess have the general form of two diametricallyY oppositely disposed ninety degree arc segments which will accept rounds of ammunition therein in any angular direction with respect to the ramming direction of the gun for guided movement toward the oblong opening adjacent to the breech of the firearm.
  • FIG. l is a perspective view, with parts broken away, of a trunnion of an elevating type gun having an ammunition guide made in accordance with the present invention
  • FIG. 2 is a rightend elevational view of the trunnion i' uit une shown in FIG. 1, with the elevating mass of the gun in one elevational position;
  • FIG. 3 is a view similar to FIG. 2, with the elevating mass of the gun in another elevational position;
  • FIG. 4 is a perspective view, partially cut away, to show ammunition fed from a magazine to the trunnion shown in FIG. l.
  • an elevating gun embodying an ammunition guide made in accordance with the present invention is shown to include a breech casing 1 having a trunnion 2 rotatably supported upon a stationary mount 3 which also supports an ammunition magazine (not shown) thereupon.
  • the breech casing 1 forms part of the elevating mass'of the gun and is rotatable about a substantially horizontal axis with respect to the stationary mount 3, from which ammunition fromV the magazine is fed to the breech casing.
  • the trunnion 2 has one end adjacent to the elevating mass of the firearm and an opposite end adjacent to the stationary mount.
  • the trunnion is formed with a passageway extending longitudinally through the opposite ends thereof.
  • This passageway at its end close to the trunnion defines an oblong opening 4 which has a longitudinal axis extending parallel to Vthe ramming direction of the gun barrel, vsuch opening restricting the passage of ammunition therethrough to belts of rounds, the longitudinal axes of which are substantially parallel to the ramming direction for the gun barrel.
  • the passageway through the trunnion widens from the oblong opening 4 adjacent to the one end of the trunnion toward the opposite end thereof into a recess forming two diametrically oppositely disposed ninety degree arc segments. These segmental openings are defined by the adjacent sides 5, 6. 7, S, respectively, of a pair of diametrically oppositely disposed blocks 9, 10.
  • angles between the respective sides 5, 7; 6, S of the blocks 9, 10 increase gradually from approximately ninety degree at the magazine end of the trunnion to adjacent to the breech end of the trunnion, at which point they define the parallel sides of the oblong opening 4.
  • the cooperating sides S, 6; 7, 8 of the blocks defining the passageway at the opposite outer end of the trunnion will orientate each round of ammunition as it is moved toward the inner one end of the trunnion and allowed to pass into the breech casing 1 through the oblong opening 4 that is in alignment with the ramming direction for the gun barrel.
  • each such round of ammunition 13 will be properly orientated into the ramming direction for the gun barrel as it is passed through the oblong opening 4 adjacent to the inner one end of the trunnion.
  • said trunnion for rotation about a substantial ⁇ horizontal elevational axis ⁇ relative to said stationary magazine, said trunnion having one end adjacent to said breech. ⁇ and another ⁇ end adjacent toy said: stationary magazine and including a passageway extending longitudinally through said trunnion adaptedf to receive ammunition fed from said magazine and meansdisposed: in said passageway and' comprising lcooperating opposing surfaces defining a passageway having a wide entry opening at the end ⁇ of the trunnion adjacent the magazine and narrowing toward the endofthe passagewayk at the breech side, said passage yway ⁇ being adaptedA to receive ammunition in various angular positionswith referencexto the' passageway entry and to orient ammunition in the passageway in correspondencewith the ramming direction ⁇ of the breech.
  • passageway at said one end of saidI trunnionv adjacent to saidy breech defines an oblong opening haw direction for said breech.
  • said outwardly iiared portion of said passageway isv gradually conformed to the shape of said oblong opening inwardly of said trunnion from said opposite end thereof, whereby ammunition entering said flared portion of said passageway out of parallelism with the ramrning direction of the gun is gradually orientated into parallelism .with said" ramming direction vduringv movement throughk said passageway.
