Abstract
Abstract A cartridge feeding and loading device for light weapons, in which the cartridges withdrawn from a cartridge belt are adapted to be moved by means of a stepwise driven follower in a stationary longitudinally extending conveyor passage and are by means of an intermittently movable pusher transferable from the conveyor passage into a corresponding bore of a rotatable disc which latter is rotatable into an angular position which corresponds to the elevational position of the weapon and thereby of the weapon magazine. In this last mentioned position of the transfer disc the pusher transfers the cartridge from the transfer disc into the magazine.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
268 words
A cartridge feeding and loading device for light weapons, which includes: longitudinally extending stationary conveying means having one end adapted to be connected to a supply of cartridges for successively receiving therefrom cartridges one behind the other, a rotatable transfer disc having its axis of rotation located near the other end of said longitudinally extending conveying means with said axis of rotation extending in a direction transverse to the longitudinal extension of said conveying means, said transfer disc having receiving passage means extending along a diameter of said disc for temporarily receiving a cartridge, said stationary conveying means having a transverse passage therethrough arranged in substantial alignment with said receiving passage means in a first position of said disc, a weapon comprising a cartridge chamber connected to said weapon and journalled as part of said weapon so as to be pivotable about an axis arranged in axial alignment with the axis of rotation of said transfer disc, said disc also being pivotable from said first position to a second position by an angle corresponding to the respective angle of elevation of the barrel of said weapon, and longitudinally extending pusher means extending in axial alignment with said transverse passage and operable to extend into and through said trAnsverse passage for transferring one cartridge at a time from said conveying means into said receiving passage means when said disc is in said first position, said pusher means also being operable after rotation of said disc to said second position to push the respective cartridge in said receiving passage means from the latter into said cartridge chamber of said weapon.
Claim 2
Dependent Claim
268 words
A cartridge feeding and loading device for light weapons, which includes: longitudinally extending stationary conveying means having one end adapted to be connected to a supply of cartridges for successively receiving therefrom cartridges one behind the other, a rotatable transfer disc having its axis of rotation located near the other end of said longitudinally extending conveying means with said axis of rotation extending in a direction transverse to the longitudinal extension of said conveying means, said transfer disc having receiving passage means extending along a diameter of said disc for temporarily receiving a cartridge, said stationary conveying means having a transverse passage therethrough arranged in substantial alignment with said receiving passage means in a first position of said disc, a weapon comprising a cartridge chamber connected to said weapon and journalled as part of said weapon so as to be pivotable about an axis arranged in axial alignment with the axis of rotation of said transfer disc, said disc also being pivotable from said first position to a second position by an angle corresponding to the respective angle of elevation of the barrel of said weapon, and longitudinally extending pusher means extending in axial alignment with said transverse passage and operable to extend into and through said trAnsverse passage for transferring one cartridge at a time from said conveying means into said receiving passage means when said disc is in said first position, said pusher means also being operable after rotation of said disc to said second position to push the respective cartridge in said receiving passage means from the latter into said cartridge chamber of said weapon.
Claim 3
Dependent Claim
37 words
A device according to claim 1, which includes motor driven control means operatively connected to said transfer disc and said conveying means and said pusher means respectively for automatically resetting them at the end of a cycle.
Claim 4
Dependent Claim
60 words
A device according to claim 1, which includes housing means for guiding said pusher means, and in which said conveying means includes casing means connected to said housing means and also includes locking means for temporarily holding the cartridges in said conveying means in their respective positions, said locking means being movable in the conveying direction of said conveying means.
Claim 5
Dependent Claim
66 words
A device according to claim 1, in which said rotatable transfer disc is located between said conveying means and said weapon and has its axis of rotation in axial alignment with the pivot axis of said weapon, anti-friction bearing means being provided for rotatably supporting said transfer disc for rotation of said transfer disc independently of the elevational pivoting movement of the barrel of said weapon.
Claim 6
Dependent Claim
69 words
A device according to claim 1, in which said receiving passage means is of approximately rectangular cross sectional to accomodate the respective cartridge for said weapon, and in which pairs of spring means are arranged opposite to each other and associated with said receiving passage means for yieldably holding a cartridge inserted into said receiving passage means while preventing said last mentioned cartridge from moving in its axial direction.
Claim 7
Dependent Claim
32 words
A device according to claim 5, in which said spring means are operable to engage groove means on opposite sides of the longitudinal axis of a cartridge in said receiving passage means.
Claim 8
Dependent Claim
59 words
A device according to claim 1, in which said transfer disc includes control abutment means and said weapon includes first abutment means for engagement with said control abutment means when said transfer disc occupies said second position, said device also including second abutment means for engagement by said control abutment means when said transfer disc occupies said first position.
Claim 9
Dependent Claim
22 words
A device according to claim 7, in which said first abutment means is firmly connected to the cartridge chamber of the weapon.
Claim 10
Dependent Claim
37 words
A device according to claim 1, which includes driving means comprising motor means and gear segment transmission means drivingly connected to said motor means for actuating said conveying means and said transfer disc and said pusher means.
