Abstract
Abstract A device for feeding of ammunition, particularly cartridges, by use of an elevator and tubular cartridge receiver for the ammunition, i.e. cartridges, especially for armored vehicles, from an ammunition magazine positioned below a platform. The platform is rotatable about a vertical axis relative to a top mounted gun with zero elevation and positioned on the platform. The elevator is secured at the underside of the platform and includes a tubular cartridge receiver associated with a spring-biased centering mechanism which extends into the free cross-sectional area of the cartridge receiver, and at least one spring-biased holder for the cartridges movable vertically relative to the longitudinal axis of the cartridge receiver. The cartridges, are stored vertically relative to the axis of the bore of the gun in the magazine therefor as well as is also being secured to the platform underside so that the same can be elevated to a point above the platform. The cartridge can then be brought into a position so as to be coaxially aligned with the bore of a gun barrel and the cartridge receiver serves simultaneously as the charging tube in which there is integrated a ram.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
288 words
A device for feeding ammunition from a vehicle interior to a weapon, gun or cannon including particularly transporting of cartridges usable with armored vehicles having a gun mounted on top of a rotatable platform thereof, said device in combination as a single unit and structurally integrated comprising: elevator means operatively connectible at the underside of said platform for receiving a cartridge from a magazine provided below said platform; cartridge receiving means operatively connectible to said elevator means for receiving a cartridge therefrom, said receiving means including; (a) a tubular cartridge receiver, said tubular cartridge receiver being connectible to and movable within said elevator means for retaining a cartridge during transport thereof from said magazine to a point above said platform, said cartridge receiver with said cartridge therein also being movable from said point above said platform to a position coaxial with the bore of said gun belonging therewith; (b) spring biased means for centering a cartridge in said tubular cartridge receiver, said centering means being adapted to extend into the free cross-sectional area of said cartridge receiver; (c) at least one spring biased holder means operatively connectible to said tubular cartridge receiver for holding a cartridge belonging therewith in said cartridge receiver, said at least one holder means being adapted to be movable perpendicular to the longitudinal axis of said cartridge receiver; ram means in said cartridge receiver for moving a cartridge into said bore of said gun, said cartridge recevier serving as a charging tube for said gun; and means for effecting pivotable movement of said cartridge receiver, said cartridge receiver including diametrically opposed apertures corresponding in shape to the forward portion of a cartridge for allowing a cartridge to be received in said cartridge receiving means.
Claim 2
Independent Claim
288 words
A device for feeding ammunition from a vehicle interior to a weapon, gun or cannon including particularly transporting of cartridges usable with armored vehicles having a gun mounted on top of a rotatable platform thereof, said device in combination as a single unit and structurally integrated comprising: elevator means operatively connectible at the underside of said platform for receiving a cartridge from a magazine provided below said platform; cartridge receiving means operatively connectible to said elevator means for receiving a cartridge therefrom, said receiving means including; (a) a tubular cartridge receiver, said tubular cartridge receiver being connectible to and movable within said elevator means for retaining a cartridge during transport thereof from said magazine to a point above said platform, said cartridge receiver with said cartridge therein also being movable from said point above said platform to a position coaxial with the bore of said gun belonging therewith; (b) spring biased means for centering a cartridge in said tubular cartridge receiver, said centering means being adapted to extend into the free cross-sectional area of said cartridge receiver; (c) at least one spring biased holder means operatively connectible to said tubular cartridge receiver for holding a cartridge belonging therewith in said cartridge receiver, said at least one holder means being adapted to be movable perpendicular to the longitudinal axis of said cartridge receiver; ram means in said cartridge receiver for moving a cartridge into said bore of said gun, said cartridge recevier serving as a charging tube for said gun; and means for effecting pivotable movement of said cartridge receiver, said cartridge receiver including diametrically opposed apertures corresponding in shape to the forward portion of a cartridge for allowing a cartridge to be received in said cartridge receiving means.
Claim 3
Dependent Claim
79 words
A device in combination according to claim 1, wherein said spring biased means for centering a cartridge in said tubular cartridge receiver includes at least three elements, said elements being evenly distributed about the free cross-sectional area of said cartridge receiver at that portion of said cartridge receiver which is closest to the cartridge exit thereof, said elements being spring biased to guide a cartridge and yet permit free passage of a cartridge belonging therewith through said cartridge receiver.
Claim 4
Dependent Claim
97 words
A device in combination according to claim 1, wherein said spring biased holder means includes a deflecting arm mountable to said cartridge receiver at that end of said cartridge receiver at which a cartridge enters, said arm having a nose-like projection at its free end for operatively engaging a flange projection of a cartridge therewith, said nose-like projection being movable out of the path of a cartridge therewith being introduced into said cartridge receiver and being returnable to operatively engage a flange projection of a cartridge therewith upon complete introduction of a cartridge into said cartridge receiver.
Claim 5
Dependent Claim
16 words
A device in combination according to claim 3, wherein said deflecting arm includes a leaf spring.
Claim 6
Dependent Claim
58 words
A device in combination according to claim 1, wherein said ram means includes a nose-like projection, said ram means being adapted to act as said holder means, whereby for the introduction of a cartridge into said cartridge receiver said nose-like projection is movable out of the path of a cartridge belonging therewith being introduced into said cartridge receiver.
