Abstract

A feature of this invention is the provision of a train of round carriers, adapted to come from a stationary supply, each carrier coupled to the next adjacent carrier by pivot means capable of unrestricted rotation, and each carrier carrying a respective round of ammunition; and a rounds orientation means, adapted to rotate in train as a function of the rotation in train of a gun and to intercept and orient each assembly of carrier and respective round, by rotation of its respective pivot means, to an orientation in train which is determined by the orientation in train of the gun.

Claims

1. An armament system comprising:

a gun adapted to rotate in train;

means which is stationary in train for supplying ammunition; and

orientation means, disposed between said gun and said ammunition supply means, and adapted to rotate in train as a function of the rotation in train of said gun;

a train of rounds carriers passing from said supply means, through said orientation means, to said gun,

each carrier coupled to the next adjacent carrier by a pivot means capable of unrestricted rotation, and each carrier carrying a respective round of ammunition;

said orientation means intercepting and orienting each assembly of carrier and respective round by rotation of its respective pivot means to an orientation in train which is determined by the orientation in train of said gun;

said gun and said orientation means rotate in train about a common axis of rotation; and

said orientation means includes a nose cam with a high portion of said nose cam which includes;

a mobile surface which is in continual oscillation through a plane of symmetry which includes said axis of rotation and which divides said single nose cam surface into two symmetrical portions whereby said high portion continually shifts from one side to the other into and out of symmetry.

2. A system according to claim 1 wherein:

said mobile surface is provided by a roller journaled on an end of a lever which is mounted by a pivot to said hollow cylinder and which lever is oscillated about said pivot.

3. A system according to claim 2 wherein:

said roller is shock mounted with respect to said pivot.

4. An armament system comprising:

a gun adapted to rotate in train about an axis,

means which is stationary in train for supplying ammunition; and

orientation means, disposed between said gun and said ammunition supply means, and adapted to rotate in train as a function of the rotation in train of said gun;

a train of rounds carriers passing from said supply means, through said orientation means, to said gun,

each carrier coupled to the next adjacent carrier by a pivot means capable of unrestricted rotation, and each carrier carrying a respective round of ammunition;

said orientation means intercepting and orienting each assembly of carrier and respective round by rotation of its respective pivot means to an orientation in train which is determined by the orientation in train of said gun;

said orientation means includes;

support means disposed for rotation about said axis and having a cutout therein for passing therethrough a carrier with a respective round of ammunition,

a hollow cylinder fixed to said support means and coaxial with said axis, and having a distal end portion cut along a substantially diagonal plane to form a symmetrical, single nose cam surface having a high portion which is 180°

out of phase with said cutout, whereby said cam surface intercepts the projectile of each round as it is passed through said orientation means, except a round which is in phase with said cutout, and cams said intercepted round and its respective carrier about its respective pivot means into an orientation whereat they are in phase with said cutout;

said high portion of said nose cam including;

a mobile surface which is in continual oscillation through a plane of symmetry which includes said axis of rotation and which divides said single nose cam surface with two symmetrical portions whereby said high portion continually shifts from one side to the other into and out of symmetry.

5. A system according to claim 4 wherein:

said mobile surface is provided by a roller journaled on an end of a lever which is mounted by a pivot to said hollow cylinder and which lever is oscillated about said pivot.

6. A system according to claim 5 wherein:

said roller is shock mounted with respect to said pivot.

7. An armament system comprising:

a gun adapted to rotate in train about an axis;

means which is stationary in train for supplying ammunition; and

orientation means, disposed between said gun and said ammunition supply means, and adapted to rotate in train as a function of the rotation in train of said gun;

a train of rounds carriers passing from said supply means, through said orientation means, to said gun,

each carrier coupled to the next adjacent carrier by a pivot means capable of unrestricted rotation, and each carrier carrying a respective round of ammunition;

said orientation means intercepting and orienting each assembly of carrier and respective round by rotation of its respective pivot means to an orientation in train which is determined by the orientation in train of said gun;

said orientation means including;

support means disposed for rotation about said axis and having a first cutout therein for passing therethrough a carrier with a respective round of ammunition,

a hollow cylinder fixed to said support means and coaxial with said axis, and having a distal end portion cut along two, substantially diagonal, mutually intersecting planes to form two, symmetrical, single nose cam surfaces, each having a respective high portion which is 90°

out of phase with said cutout, and also two low portions, one of which is in phase and one of which is 180°

out of phase with said cutout, whereby one or the other of said cam surfaces intercepts the projectile of each round as it is passed through said orientation means, except a round which is either in phase or 180°

out of phase with said cutout, and cams said intercepted round and its respective carrier about its respective pivot means into an orientation whereat they are either in phase or 180°

out of phase with said first cutout.

8. A system according to claim 7 further including:

additional cam means coupled between said hollow cylinder and said first cutout for receiving from said cylinder rounds which are either in phase or 180°

out of phase with said first cutout and for passing an in-phase round to said cutout without changing its orientation and for camming an out-of-phase round and its respective carrier about its respective pivot means into phase with said first cutout.

9. A system according to claim 8 wherein:

said additional cam means comprises an additional hollow, cylinder having;

a first guide surface therein for engaging the carrier of an in-phase round, and

a second guide surface therein for engaging the carrier of an out-of-phase round.
