Definitions
- a cartridge feeding device for a gun the magazine of which includes two compartments cusposed on opposite sides of the gun and a common discharge opening for cartridges.
- Cartridge transfer means feed the cartridges, one by one, alternately from the two compartments to the discharge opening.
- Such alternate feeding of the cartridges is effected when and while the cartridge loading mechanism transports a cartridge pickedup at the discharge opening of the magazine to a ps1t1on for ramming the cartridge.
- the movements of the cartridge transfer means and the loading mechanism are synchronized by linkage means interconnecting the transfer means and the loading mechanism.
- the invention relates to a device for feeding forward cartridges in a cartridge magazine, in particular in a twin cartridge magazine comprising two compartments located on either side of a reciprocating cartridge rammer of a gun, in accordance with the reciprocating movement of the rammer.
- Cartridge magazines of automatic guns are known in which the cartridge magazine may contain a plurality of cartridges arranged side by side adjacent each other and, as the case may be in vertical rows above each other.
- the cartridge magazine may contain a plurality of cartridges arranged side by side adjacent each other and, as the case may be in vertical rows above each other.
- proper distribution of weight of cartridges is of great significance for the precision of aim while the magazine is being emptied during firing.
- a device comprises, for the transfer of cartridges from the magazine to a loading mechanism for feeding forward each cartridge from a cartridge outlet port of the magazine to a ramming position in alignment with the gun barrel, cartridge transfer means cooperative with said reciprocating loading mechanism to feed forward a cartridge to said loading mechanism alternately from the magazine compartments located on either side of the center longitudinal vertical plane of the gun.
- cartridges are thus to be fed out alternately from a left-hand magazine compartment and from a right-hand magazine compartment to the loading means to be then further transferred to the cartridge chamber of the barrel.
- the invention relates to a device of the kind described of a gun provided with a reciprocating cartridge loadlng mechanism and comprising, for each magazine compartment located on either side of the central vertical plane of the gun, a reciprocating cartridge transfer means which during a feed motion pushes forward a cartridge to a position for being further conveyed to the barrel by means of the loading mechanism and then returns to the start position for a following motion for feeding forward a cartridge.
- the cartridge transfer means of one compartment is to be subjected to a cartridge feeding motion for every second reciprocating motion of the loading mechanism and the cartridge transfer means of the second magazine compartment for each intermediate reciprocating motion of the loading mechanism.
- said reciprocating cartridge transfer means of said two magazine compartments are each connected to a common rotational drive shaft in a push-pull arrangement, that is to say so that the cartridge transfer means of one magazine compartment is subjected to a feed movement as the cartridge transfer means of the second compartment returns into the position for a following feed motion, and vice versa, and that the reciprocating loading mechanism of the gun is in driving connection with a first member of a unidirectional coupling, the second coupling member of which is in driving connection with the drive shaft common to the cartridge transfer means of the two magazine compartments.
- the gearing ratio of the drive transmission from the reciprocating loading mechanism to said shaft is so selected that the cartridge transfer means of each magazine compartment performs a feeding motion or a return motion, respectively, for each oscillation of the reciprocating loading mechanism in the direction at which the members of the unidirectional coupling are in engagement.
- the cartridge transfer means of the respective magazine compartment are of the kind, known per se, with which the step-wise cartridge transfer is provided by means of reciprocating cartridge pushers which are each connected to a bar reciprocating in its longitudinal direction for feeding forward a number of carcartridges, each time one step in the direction towards the magazine outlet.
- the reciprocating bars are connected to each one crank of the shaft and the shaft is non-rotatively connected to one of the members of the unidirectional coupling, the second coupling member, namely the one connected to the loading mechanism and performing an oscillating motion together therewith, being connected to the loading mechanism at a gearing ratio so selected that the drive shaft rotates half a revolution for each motion in one direction of the loading mechanism.
- the cartridge transfer means of one magazine compartment thus moves forward while pushing the cartridges one step in the direction toward the magazine outlet and the cartridge feeding means of the second compartment returns into position for a following feed, and vice versa during a successive oscillating motion of the loading mechanism.
- a further object of the invention is to provide means for exactly controlling the positions of the driving shaft connected to the cartridge transfer means after each feed motion of the drive shaft.
- the driving shaft comprises two deten ts extending radially of the shaft, one for each position of the shaft in which the cartridge transfer means in one of the magazine compartments occupies the start position for a feed movement and the cartridge transfer means of the second magazine compartment in its end position after having fed forward a cartridge to the loading mechanism.
- Said detents are cooperative With a detent mounted on a stationary support, either the detent mounted on the support or each one of the detents mounted on the driving shaft being displaceable out of engagement with a detent cooperative therewith to stop the shaft in one of its determined positions.
- Said displaceable detent or detents comprise actuating means which during part of the motion of the reciprocating coupling component in the direction in which the unidirectional coupling is in driving engagement to rotate the driving shaft can bring the displaceable detent out of engagement with the projection cooperating therewith to stop the shaft in a predetermined position.
- said coupling component may comprise two detents located on diametrically opposite sides of this coupling component, said first, reciprocating component of the coupling comprising a pivotal spring-actuated latch, cooperative with the detents of the second component in one direction.
