Abstract

Abstract In a tank or similar military vehicle having a main weapon located atop a tary basket, the improvement comprising one or more ammunition storage magazines located within the vehicle hull behind the basket. Transfer mechanisms are employed to move individual rounds of ammunition from the storage magazines into a rammer located within the basket. The rammer moves the ammunition round upwardly into the firing chamber of the weapon. The system is designed to provide storage capacity for large numbers of ammunition rounds. Another design objective is to provide a transfer mechanism that accomplishes a weapon loading cycle in a relatively short time span.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 271 words
In a military vehicle comprising a hull having a longitudinal centerline, a circulr basket located in the hull for powered rotary motion in the azimuth direction, and an external weapon mounted atop the basket in the space above the hull: the improvement comprising means for storing individual rounds of ammunition within the hull outside the basket; said ammunition storing means comprising structure operable to position the stored rounds in parallel rows, with each stored round assuming an upright attitude; a carrier for an individual round movable outside and along the basket perimeter in arc centered on the basket rotational axis; first mechanical means for transferring individual rounds of ammunition from the ammunition storing means to the carrier when the carrier is stationed on the hull longitudinal centerline; said first mechanical transfer means being constructed so that the round is maintained in an upright attitude while it is being moved from the storing means into the carrier; a mechanical round rammer movably located within the basket for upward motion to insert an individual round into the weapon; and second mechanical means for transferring an individual round from the carrier to the rammer; said second mechanical transfer means being constructed to maintain the round in an upright attitude while it is being moved from the carrier into the rammer; said basket and carrier being independently rotatable; said second mechanical transfer means being movable on a radial line through the basket rotational axis, whereby the second transfer means is able to transfer an individual round of ammunition from the carrier into the rammer when the basket is in a variety of different rotated positions.
Claim 2
Dependent Claim 271 words
In a military vehicle comprising a hull having a longitudinal centerline, a circulr basket located in the hull for powered rotary motion in the azimuth direction, and an external weapon mounted atop the basket in the space above the hull: the improvement comprising means for storing individual rounds of ammunition within the hull outside the basket; said ammunition storing means comprising structure operable to position the stored rounds in parallel rows, with each stored round assuming an upright attitude; a carrier for an individual round movable outside and along the basket perimeter in arc centered on the basket rotational axis; first mechanical means for transferring individual rounds of ammunition from the ammunition storing means to the carrier when the carrier is stationed on the hull longitudinal centerline; said first mechanical transfer means being constructed so that the round is maintained in an upright attitude while it is being moved from the storing means into the carrier; a mechanical round rammer movably located within the basket for upward motion to insert an individual round into the weapon; and second mechanical means for transferring an individual round from the carrier to the rammer; said second mechanical transfer means being constructed to maintain the round in an upright attitude while it is being moved from the carrier into the rammer; said basket and carrier being independently rotatable; said second mechanical transfer means being movable on a radial line through the basket rotational axis, whereby the second transfer means is able to transfer an individual round of ammunition from the carrier into the rammer when the basket is in a variety of different rotated positions.
Claim 3
Dependent Claim 80 words
The improvement of claim 1: said ammunition storing means comprising two separate magazines on each side of the hull longitudinal center line; each magazine comprising a plurality of upright partitions operable to position the stored rounds in rows normal to the hull longitudinal centerline; said rows communicating with a central corridor extending along the hull centerline; said first transfer means being movably positioned in the corridor for transferring individual rounds of ammunition from a selected row to the aforementioned carrier.
Claim 4
Dependent Claim 36 words
The improvement of claim 2: each magazine including individual round conveyors in each row for selectively moving the ammunition in each row toward the central corridor, to thereby deliver selected rounds to the first transfer means.
Claim 5
Dependent Claim 47 words
The improvement of claim 3 wherein the stored rounds are located below a hull upper wall in close proximity to the wall undersurface; said upper wall having two hatch openings therethrough for loading rounds of ammunition into the separate magazines, and an armored closure in each opening.
Claim 6
Dependent Claim 41 words
The improvement of claim 4, and further comprising a gunner's seat within the basket, said seat facing away from the mechanical rammer so that when the gunner is facing forwardly the rammer will be behind him on the hull longitudinal centerline.
Claim 7
Dependent Claim 33 words
The improvement of claim 5 wherein the second transfer means comprises a powered pusher member (68) slidably positioned on the carrier for motion along a radial line measured from the basket rotational axis.
Claim 8
Dependent Claim 49 words
The improvement of claim 6 wherein the first transfer means is movably arranged in the aforementioned corridor to move a round of ammunition to a discharge position above the pusher member, whereupon the round is allowed to move downwardly into the pusher member for subsequent transfer to the rammer.
