Abstract
Description
- This invention relates to an ammunition conveyor system for providing rounds of ammunition seriatim from a stationary supply to a gun in a turret which has unrestricted rotation in train.
- Conventional systems for providing rounds seriatim to a gun rotating in train have been of two kinds: (1) flexible chute or link systems, shown, for example, in U.S. 3,437,005 issued to J. M. Trumper on April 8, 1969; U.S. 3,650,176 issued to G. Linder on March 21, 1972; and on page 161 of "The Gatling Gun" by Wahl and Toppel, Arco Publishing Co., Inc., New York, 1965. (2) Rotary differential mechanisms, shown, for example, in U.S. 3,974,738 issued to E. A. Mayer on August 17, 1976. Neither system type permits unlimited rotation in train. After the gun has rotated 360° more or less in one direction, it must unwind back in the other direction. If the gun is to have unlimited rotation in train, then the supply cannot be stationary, it must rotate with the gun. Some pivoting of rounds is shown in U.S. 3,021,761 issued February 20, 1962, to F. G. Tillander and in U.S. 3,901,123 issued August 26, 1975 to L. I. Jayne et al. While most conveyor or link systems are designed to preclude unlimited pivoting of one conveyor or link with respect to the next adjacent one, U.S. 2,851,927 issued September 16, 1958 to W. G. Smith shows telescoped rounds fixed to lengths of flexible cable.
- It is an object of this invention to provide an ammunition conveyor which will supply a train of rounds to a gun in a turret which has unrestricted rotation in train.
- A feature of this invention is the provision of a train of rounds 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.
- These and other objects, features and advantages of this invention will be apparent from the following specification thereof taken in conjunction with the accompanying drawing in which:
- FIG. 1 is a diagrammatic showing of a gun turret system embodying this invention;
- FIG. 2 is a perspective view of a carrier assembly for a round of ammunition permitting unrestricted swiveling between immediately adjacent carrier assemblies;
- FIG. 3 is a perspective view of the carrier assembly of FIG. 2 in a disassembled state;
- FIG. 4 is a perspective view of a train of the carrier assemblies of FIG. 2 with respective rounds of ammunition, showing unrestricted swiveling about the longitudinal axis of the train;
- FIG. 5 is a side view in elevation of a first embodiment of the rounds orientation mechanism through which the train of carrier assemblies of FIG. 4 passes from the stationary supply to the rotating-in-train gun;
- FIG. 6 is a front view in elevation of the assembly of FIG. 5;
- FIG. 7 is a perspective view of the orientation cam;
- FIG. 8 is a side view in elevation of a second embodiment of the rounds orientation mechanism through which the train of carrier assemblies of FIG. 4 passes from the stationary supply to the rotating-in-train gun;
- FIG. 9 is a front view in elevation of the assembly of FIG. 8; and
- FIGS. 10 through 17 are bottom views in cross- section through the assembly of FIG 9 taken along the planes X-X through XVII-XVII respectively.
- As seen in FIG. 1, the gun turret system includes a
gun turret 10 having agun 12 which is unrestricted in its rotation in train or azimuth with respect to astationary deck 14. The turret, for example, may be of the type shown in U.S. 3,766,826 issued to H. M. A. Salomonsson on October 23, 1973, or U.S. 3,995,509 issued to L. F. Backus et al on December 7, 1976. Rounds of ammunition are provided to the gun from anammunition handling system 16 which is stationary with respect to the deck. The handling system may be generally of the type shown in U.S. 4,004,490 issued to J. Dix et al on January 25, 1977, but without a return of fired cases to the storage drum, or U.S. 3,788,189 issued to H. G. Sachleben, Sr., et al. on January 29, 1974. In the system specifically shown in FIG. 1, thesupply 16 is of the type wherein a linked belt of ammunition is hung in festoons from support elements, as shown, for example, in U.S. 2,573,774 issued to R. N. Sandberg on November 6, 1951, or U.S. 2,710,561 issued to A. A. Dowd on June 14, 1955, or the H. C. Foshag designed system used with the 20mm towed vulcan air defense system. The rounds of ammunition travel from the supply to the gun in atrain 18 of interconnectedcarriers 20. Thetrain 18 passes through alower chute 22 from the supply to arounds orientation mechanism 24 and therefrom through abooster 25 and anupper chute 26 to thefeeder 28 of thegun 12. - As seen in FIGS. 2, 3, and 4, the carriers are a modified form of a
conventional link 30 such as the XM28AS-78D006-002. Each link comprises afirst element 32 having a yoke shape with acentral portion 34 and twodistal portions element 40, adapted to snap onto the case between theportions bent fingers hole 46 in thecentral portion 34. Aclip 47 having a "U" shaped aperture therein is adapted to engage the bent fingers to interlock the twoelements hole 46 may be made substantially elliptical and the fingers substantially flat to normally align the two elements in parallel, yet permit full 360° rotation about a diameter through the cartridge case, between the two elements via the rotation of the fingers within the hole. This diameter of the case should preferably pass through the centroid of the assembly of round and clipped thereon to link elements. The link may include a special orienting element, such as a bent-inelement 48 to engage anannular groove 50 in thecase 52 of theround 54. The link may also includeguide feet chutes - As seen in FIGS. 5, 6 and 7, the first embodiment of the
rounds orientation mechanism 24 comprises aplate 60 which has fixed thereto ahollow cylinder 62 which is coaxial with the axis ofrotation 64 of the turret in azimuth, and is coupled to the turret to rotate therewith. The plate has acutout 66 therein adapted to pass a carrier assembly and a respective round of ammunition in a predetermined orientation to the axis ofrotation 64. Thecylinder 52 is :ut at its distal end along a substantially diagonal plane, to form a symmetrical, singlenose cam surface 68. The nose of the cam, the axis ofrotation 64, and the longitudinal axis of the round of ammunition as it passes through thecutout 66 all lie in a common plane. Thecam surface 68 is symmetrical with respect to this common plane. - A
roller 80 is journaled for rotation at the end of alever arm 82 which is mediately mounted to thecylinder 62 by apivot 83 passing through an oversize hole in the arm. Aspring 84 biases the arm downwardly against the pivot. The other end of thearm 82 has apocket cam surface 85 which is engaged by aneccentric cam 86 fixed on ashaft 88 which is driven by suitable shafting from the turret. As theshaft 88 turns, the lever with the roller dithers to and fro a few degrees. Theroller 80 serves as the actual nose of thecam surface 68, and the high point of this actual nose is in continual movement with respect to the remainder of the cam surface. The purpose of this moving nose is to preclude a round of ammunition, as it passes through the rounds orientation mechanism, from being perfectly aligned with the plane of symmetry, but 180° out of alignment with thecutout 66, and hanging up on the nose. The inside diameter of thecylinder 62 is made small enough that the nose engages the side of the projectile of the round, yet large enough that the base of the cartridge case clears the inner wall of the cylinder. Optionally, an additional pair ofelements 90 may be fixed within the cylinder to providerespective cam surfaces 92 each adapted to engage the base, i.e., the extractor disk, of a cartridge case. In operation, as each round of ammunition is carried along into the rounds orientation mechanism, its projectile will abut thecam surface 68 and the round and its associated carrier assembly will be progressively swiveled about its respective pivots with the next succeeding and next preceding carrier assemblies. As the round approaches alignment with thecutout 66, its extractor disk will engage one or the other of the cam surfaces 92 and be guided thereby. Alternatively, theelements 90 may be omitted, and thecutout 66 may be provided with a downwardly extendingbellmouth 94 to guide the base portion of the round into thecutout 66. - As the round and its carrier assembly pass through the
cutout 66 they enter thebooster 25 and then theupper chute 26 which leads to theloader 28 of thegun 12. Thebooster 25 has asprocket 91 which assists in the pulling of the train of rounds up through the rounds orientation mechanism and third delivery into the loader. The loader has an in-feed sprocket which pulls the train of rounds into an extraction mechanism to remove each round in sequence from its carrier assembly. Each stripped round is then fed into the gun. The extraction mechanism may, for example, be of the type shown in U.S. 3,333,506 issued to R. W. Henshaw et al on August 1, 1967. - While the embodiment here shown has had the rounds orientation mechanism acting directly upon the projectile as it is carried by its carrier, it will be appreciated that the mechanism can be made to act upon the carrier, for example, if the carrier were made longer than the round of ammunition.
- As seen in FIGS. 8 through 17, the second embodiment of the
rounds orientation mechanism 100 comprises aplate 102 which has fixed thereto ahollow cylinder 104 which is coaxial with the axis ofrotation 64 of the turret in azimuth, and is coupled to the turret to rotate therewith. Theplate 102 has a cutout 106 (similar to cutout 66) therein adapted to pass a carrier assembly and a respective round of ammunition in a predetermined orientation to the axis ofrotation 64. Thecylinder 104 is cut at its distal end along two, substantially diagonal, mutually intersecting planes, to form two, symmetrical, single nose cam surfaces 108 and 110. The two noses, the axis ofrotation 64, and the longitudinal axis of the round of ammunition as it passes through thecutout 106 all lie in acommon plane 124. Each of the cam surfaces 108 and 110 is symmetrical with respect to thiscommon plane 124. A ditheringroller assembly 112 and 114 is respectively mounted on each nose, as described with respect to the first embodiment, to preclude a round of ammunition from hanging up on the nose. - As each round is pulled up into the orientation mechanism, its projectile will engage either the
cam surface 108 or thecam surface 110, and the round will be deflected up to 90° into alignment with thecutout 106 in theplate 102. However, as it passes through thecutout 106, the round will be either aligned with thechute 26 leading to the feeder of the gun or 180° out of alignment with thechute 26. A second stage orientation mechanism is fixed to and between theplate 102 and thechute 26. This mechanism comprises anouter tube 120 which is an extension of thetube 104, coaxial with theaxis 64, whose interior wall just clears the base of the round, and aninterior tube 122, also coaxial with theaxis 64. More than the front portion of theouter tube 120 is omitted along a plane which is parallel to theplane 124 which passes through the centerline of thecutout 106. Theround 116 is shown aligned with thecutout 106. Theround 118 is shown 180° out of alignment with thecutout 106. The distal margins of theouter tube 120 are bent to provide twoguide surfaces cutout 106. Theinner tube 122 has twohelical slots slot 130 is adapted to clear the diameter of the projectile of a round. Theslot 132 is adapted to clear the diameter of the case of a round. Theinner tube 122 has a plurality of guides fixed to its edges which bound these helical slots.Guides feet carrier 30, guides 140 and 141 are adapted to bear on the projectile, and guides 142 and 143 are adapted to bear on the case, all to guide a misaligned round through the helical slots, as it is pulled upwardly through the orientation mechanism, into theupper chute 26. (No booster has been shown between the orientation mechanism and the upper chute, but a booster may be provided as shown in FIG. 6). As shown in FIGS. 10 through 17, around 118 which is 180° misaligned, is progressively rotated, as it is pulled upwardly, into alignment withupper chute 26. Theupper chute 26 is aligned with thecutout 106. Around 116 which is aligned with thecutout 106 is pulled up without rotation between theguides
