Definitions
- the invention relates to a firing and safety stop system. long-range for a small or multi-tube automatic firearm medium caliber, this weapon comprising a body which supports in rotation an assembly rotating around an axis parallel to the direction of fire of the tubes of the weapon, this rotating assembly including the barrels of the weapon and a loading system and firing ammunition for the gun tubes to fire successively an ammunition during each rotation of the rotating assembly.
- the stop system firing or long-range security essentially has the function of order the immobilization of the rotating assembly of the weapon either at following the voluntary actuation of an external order stop shooting, for example during or at the end of a ammunition burst, either automatically after firing defective ammunition through one of the gun tubes for security reasons.
- the main object of the invention is to design a system fire stop and safety fire in which immobilization of the rotating assembly of the weapon can be carried out under the best possible conditions taking into account kinetic energy of the rotating assembly of the weapon at the time where the firing stop or fire safety system is activated.
- the invention proposes a firing stop system and safety kit for a multi-tube automatic firearm small or medium caliber, which is characterized in that it comprises a rotating immobilization system for the rotating assembly of the weapon, this system comprising mounted shock absorbing means coaxially with the rotating assembly of the weapon, a device for control comprising a cylindrical body coaxial and integral in rotation with this rotating assembly and also movable in translation, and means to cause this translational displacement as a result of the detection of a defective round of ammunition or actuation of an external fire stop command, to compress the damping means and absorb the kinetic energy of rotation of the rotating assembly of the weapon, the relaxation of the damping means causing then a rotation in opposite direction of the rotating assembly of the weapon before it stops.
- the axis of rotation of the rotating assembly is materialized by a central shaft fixed which is extended axially by a rod, one of which end is fixed to the central shaft by means of a hitch, while its other end supports a lock washer.
- the means shock absorbers consist of two stacks of spring rings respectively housed in two tubes telescopic mounted sliding along the axis of rotation of the rotating assembly.
- the first telescopic tube has, at one end, a bottom wall crossed by the rod central, the second telescopic tube which is intended for engage, at one end, in the other end open of the first telescopic tube also has a bottom wall crossed by the central rod, so that the spring rings of the first stack are supported respectively on the two bottom walls of the two tubes, while the spring rings of the second stack respectively bear on the wall of bottom of the second telescopic tube and on the washer stop carried by the central rod.
- the means for cause the body to move in translation cylindrical which allows compression of the means shock absorbers, include a sleeve that surrounds the body cylindrical, connecting means between the sleeve and the cylindrical body on the one hand, drive in rotation the sleeve in synchronism with the cylindrical body and, on the other hand, allow the translational movement of the cylindrical body relative to the sleeve, and a sleeve rotation stop device to cause the displacement in translation of the cylindrical body, this stop device being activated after firing defective ammunition or external control stop shooting.
- the means of connection between the element which allows the compression of the means shock absorbers and the sleeve are constituted by rollers located on the periphery of the cylindrical body hereinafter referred to as roller carriers and by grooves helical formed in the wall of the sleeve, so that each groove receives a roller.
- the stop device in rotation of the sleeve comprises a plurality of heels evenly distributed around the periphery of the sleeve and a retractable trigger fixed in rotation relative to the sleeve and movable between a lowered position or retracted and a raised position where the trigger is located on the circular movement path of heels to be able to immobilize the rotating sleeve.
- the number of heels of the sleeve is equal to that of the tubes of the weapon, so as to associate a heel to each tube.
- the trigger consists of a flap pivoting articulated around an axis supported by a support trigger which is fixed in rotation relative to the sleeve and which is mounted opposite the latter.
- the heel associated with a gun barrel goes past the trigger after firing the ammunition fired by this tube and before that of the ammunition fired by the next tube.
- the stop device in rotation of the sleeve is notably actuated as a result detection of a failure in firing a ammunition.
- This failure can be detected by noting the absence of combustion gases or a recoil movement of the weapon within a period of time determined.
- we will consider means of detection sensitive to combustion gas pressure.
- the passage of the trigger in the lowered position and / or recorded is provided by one of several means of detection and control mounted on a solid support in rotation of the rotating assembly of the weapon, the number of these control means being equal to that of the tubes of the weapon to associate a control means to each tube.
- each means control consists of a movable element between a retracted position and an active position where it can act on the trigger, this element being movable by a position to another by borrowing combustion gas from the ammunition fired by the tube associated with this means of control, this mobile element can be the rod of piston of a jack, the cylinder of which communicates with the tube associated with this mobile element.
- the invention contemplates two principles of operation according to the position occupied by the retractable trigger in normal weapon operation.
- the trigger is in position raised before firing an ammunition, which implies a first operating principle according to which the trigger must be retracted after firing a ammunition by a tube so that the heel of the associated sleeve to this tube can pass freely in front of the trigger, the latter being then raised after the passage of the heel and before firing a round of ammunition.
- this first embodiment it is then provided a device for lowering and a device to raise the trigger, these two devices being successively actuated by the associated control means to the tube that just fired an ammunition.
- the movable element of this control means is in its retracted or rest position before firing the ammunition and, in normal operation of the weapon, passes in its active position when the ammunition is fired by borrowing combustion gases.
- Devices for lowering and raising the trigger each consist of a linked linkage hinged to the trigger to rotate it one way or the other.
- Each of these linkages includes at least one cam means which is located on the displacement path of the movable element of the control means associated with the tube which fires ammunition, when this control element is in its position active so as to act successively on the cams of the device for lowering and device for raising the trigger.
- the movable element of the faulty tube control means In the event of a malfunction during the firing ammunition through one of the barrels of the weapon, such as example a failure which results in a non-firing of the ammunition or a delay in firing the ammunition, the movable element of the faulty tube control means remains in its rest position due to the absence of combustion gases or their retardation. In these conditions, the cams of the devices for lowering and raising the trigger are no longer located in the path of displacement of the movable element and the trigger is therefore maintained in the raised position, i.e. on the displacement trajectory of the heels of the sleeve. The heel associated with the faulty tube will then come up against against the trigger and will cause immobilization in sleeve rotation.
- the external fire stop command during of a burst is designed to retain in a retracted position the movable element of the means command associated with one of the tubes of the weapon, when this tube will fire ammunition.
- the trigger is maintained in its raised position after firing the ammunition and it will cause, as in the case of a malfunction when firing a munition, a immobilization in rotation of the sleeve and displacement in translation of the roller carrier.
- the damping means are always ordered as a result of immobilization in rotation of the sleeve, both in the case of shooting defective ammunition only in the case of actuation of the external fire stop command.
- the trigger is held in the lowered position, which involves a second reverse operating principle to that envisaged previously.
- this second embodiment it is provided a device to hold the trigger in lowered position and a device for raising it only following the faulty firing of an ammunition or the actuation of the external fire control to cause the sleeve to stop rotating.
- the movable element of the associated control means on each barrel of the weapon is however in its position active before firing ammunition, and borrowing gas is used when firing the ammunition to move the movable element in its retracted position so as to what he cannot act on the device for raise the trigger.
- the device for raising the trigger also includes, as in the first embodiment, a cam located on the trajectory for moving the movable element of the control means when this movable element is in its active position.
- the element mobile of the control means associated with this tube remains in its active position to be able to act on the device which allows the trigger to be raised before the passage of the sleeve heel associated with the tube and cause immobilization in rotation of the sleeve when this heel comes into contact with the trigger.
- the external fire stop command during of a burst for example is designed to retain in its active position and not in its retracted position as in the first embodiment, the element mobile of the control means associated with one of the tubes, when this tube fires ammunition to be able to act on the device which raises the trigger before the passage of the heel of the sleeve associated with the tube which draws the ammunition and thus causing immobilization in rotation of the sleeve.
- the external fire control in the two embodiments is only intended to act on one of the tubes of the weapon. Under these conditions, when the external fire control is activated during of a burst, the weapon can still fire at least a number ammunition equal to the number of tubes of the front weapon effective stopping of the weapon, i.e. the weapon does not can not fire piecemeal but this mode of operation is not of major interest for a GATLING type firearm.
- This second embodiment presents in particular the advantage of saving wear and tear on all of the mechanisms that are used to lower and raise the trigger. Indeed, for each rotation of the whole turning the weapon and in normal operation the first embodiment requires lowering and pull the trigger up a number of times equal to the number of tubes, while in the second embodiment the trigger remains in the retracted position and is not necessary to request the mechanisms to raise and lower the trigger.
- the kinetic energy of the rotating assembly of the weapon is absorbed by the damping means, this which avoids almost instantaneous immobilization likely to create mechanical stress important in terms of rotating support bearings of the rotating assembly of the weapon.
- FIG. 1 A small multi-tube automatic firearm or medium caliber is schematically illustrated in Figures 1 and 2.
- This weapon 1 of the GATLING type, comprises a body 3 which rotatably supports a rotating assembly.

- the SC loading and firing system includes also several chambers 20 mounted around the tree fixed central 12 inside the housing 8 of the body 3. These chambers 20 are for example four in number, each chamber being associated with a weapon tube. Each chamber 20 is pivotally mounted around a tie rod 22 parallel to the fixed central shaft 12 and integral in rotation of the loading block 10. The chambers 20, at during the rotation of the loading block 10, are by example guided between two separate fixed cams one of the other by a constant distance corresponding to outer diameter of the chambers 20.
- a SE system for ejecting the sockets ammunition fired is mounted in the housing 9 of the body 3.
- This SE system includes for example two wheels star 24, coaxial with the shaft 12 and integral in rotation of the tie rods 22.
- Each percussion device 25 is actuated from a control device 27.
- the housing 9 in which the system is mounted SE ejection of the sockets is closed by a part 30 which supports the tie rods 22 as well as the T tubes which extend beyond this part 30 which is integral in loading block 10 rotation (figure 1).
- an organ external motor M such as a gear motor, has a drive shaft output which supports a drive pinion 32 which comes mesh a toothing 34 provided at the periphery of the support piece 30 for rotating the assembly turning of the weapon.
- the rotating assembly 100 of the weapon comprises in particular the loading block 10, the tie rods 22 and the associated chambers 20, the T tubes and the system SE ejection of ammunition casings, assembly to which we combine a long fire stop and safety system fire which has the function of ensuring the immobilization of the rotating assembly 100 of the weapon as a result of the firing defective ammunition by one of the T tubes of the weapon or actuation of an external stop command shoot.
- the fixed central shaft 12 which crosses the rotary block 100 of the weapon is extended axially by a central rod 104, one end of which is fixed to said shaft 12 by means of a coupling 106.
- the rod 104 supports a support washer 108, retained by a nut 110 screwed onto the rod 104 and crossed by the tubes T of the weapon.
- Hitch 106 includes sleeve 114 integral with rod 104 and mounted to slide on said rod tree 12. As shown in figure 3, two pins fixed 116 are engaged in the body of the sleeve 114, perpendicular to the axis of the latter, so that radially protrude into two axial slots 118, diametrically opposite and arranged on the surface peripheral of the central shaft 12. The two ends lights 118 each form a stop which limits the axial displacement of the sleeve 114 of the coupling 106.
- Long shot stop and safety system fire includes a 120 immobilization system in rotation of the rotating assembly 100 of the weapon.
- this system 120 includes in particular a damping device consisting of two stacks of spring rings 122a and 122b respectively housed in two telescopic tubes 124a and 124b mounted sliding on the central rod 104.
- the first telescopic tube 124a has, at one end, a wall of bottom 125 crossed by the central rod 104 and intended to bear against a cylindrical support block 126 interposed between the coupling 106 and the first tube telescopic 124a, this support block 126 will be described further.
- the first tube 124a is open to receive telescopically a end of the second tube 124b.
- the end of the second tube 124b which engages the interior of the tube 124a also has a wall of bottom 125 crossed by the central rod 104.
- the spring rings 122a housed in the first tube 124a and arranged around the central rod 104 are trapped between the two bottom walls 125 of the two tubes 124a and 124b, while the spring rings 122b housed in the second tube 124b and arranged around the central rod 104 are trapped between the wall of bottom 125 of tube 124b and the support washer 108 provided at the free end of the central rod 104.
- the second tube 124b extends slightly beyond the support washer 108, the diameter of which is slightly smaller than the internal diameter of the tube 124b, and freely crosses a radial plate 130 traversed by the four T tubes of the weapon and which is integral with these last.
- the second tube 124b ends in a flange external radial 132 intended to bear against the plate 130 and thus limit the degree of penetration of the tube 124b inside the tube 124a.
- a control device to compress the spring rings 122a and 122b of the device damping includes cylindrical support block 126 above which is interposed between the coupling 106 and the tube 124a.
- This support block 126 is mounted coaxially and integral in rotation with the rotating assembly 100, all by being movable in translation along the tubes T of the weapon that cross it right through.
- the device to compress the spring rings 122a and 122b also includes means for causing the translational movement of the support block 126 by following the faulty firing of an ammunition or activation of the external fire control, means which will be described below.
- the block support 126 supports at its periphery rollers 135 regularly distributed around this block called below roller holder 126.
- the rollers 135 are respectively received in helical grooves 137 formed in the cylindrical wall of a sleeve 140.
- This sleeve 140 is attached around the roller holder 126 and is supported in rotation by two spacers 142 and 143 ( Figure 2).
- the rollers 135 transmit the sleeve 140 the rotation movement of the roller carrier 126 while allowing the latter to move in translation when the sleeve 140 is immobilized in rotation by a stop device 145.
- the stop device 145 is constituted by a trigger G retractable capable of cooperating with one of several heels 150 regularly distributed around the sleeve 140.
- the number of heels 150 is equal to that tubes of the weapon, so as to associate a heel 150 with each tube T.
- Trigger G is fixed in rotation with respect to the rotating assembly 100 of tear.
- Trigger G is pivotally mounted on a block or trigger support 152 facing the sleeve 140.
- the trigger G is constituted by a flap of overall rectangular shape, one side of which a stop for the heels 150 of the sleeve 140.
- the trigger G is pivotally mounted around a fixed axis 154 supported by trigger support 152 and which extends parallel to the axis of rotation of the assembly turning 100 materialized by the central shaft 12 and the rod 104.
- the trigger G can take either a position lowered or retracted to lie outside the trajectory of movement of the heels 150 during the rotation of the sleeve 140, i.e. a raised position for be located on this trajectory at a point such that the first heel likely to come into contact with the trigger G for immobilizing the sleeve 140 in rotation, is the one associated with the tube T located in the area of shot of the weapon's operating cycle, i.e. as long as the chamber is axially aligned with the tube.
- the trigger G is in the raised position before firing a ammunition by one of the T tubes of the weapon.
- the device 155 to lower the trigger G is constituted by a pivoting lever 157, one end of which is hinged around a fixed point 158 of the trigger support 152.
- the other end of lever 157 is articulated on the trigger G in such a way as a pivoting movement lever 157 causes a pivoting movement of the trigger G around its axis 154.
- the articulation between the lever 157 and the trigger G is for example constituted by a pin 160 carried by lever 157 and by a oblong light 162 formed in the trigger G for receive the pin 160.
- the lever 157 supports a boss 164 which constitutes a contact surface forming a cam used to rotate lever 157 and lower the trigger G, as will be described later.
- the device 165 for raising the trigger G ( Figure 4) is constituted by a cam 167 secured to the trigger G, i.e. cam 167 can pivot simultaneously with trigger G around the axis 154.
- This cam 167 defines a surface 169 on which comes a means of control to raise trigger G, as it will described below.
- the devices 155 and 165 for lowering and raising the trigger G are successively actuated by one of several detection and control means 170.
- These control means 170 are mounted on a support 172 integral in rotation with the rotating assembly 100 of the weapon, and their number is equal to that of the T tubes of tear.
- each control means 170 consists of a movable element can take either an active position used for control devices 155 and 165 to lower and raise the trigger G by acting respectively on the boss 164 of lever 157 and on the bearing surface 169 of cam 167, either a neutral or rest position not involving any action on trigger G.
- This element mobile is for example constituted by the piston rod 175 of a cylinder 177, and also forms a means of detection sensitive to combustion gas pressure generated after firing an ammunition.
- a control means 170 is associated with each tube T, i.e. the cylinder 178 of the cylinder 177 associated with each tube T is put in communication by a passage 180 with the associated tube T to transmit to the cylinder 178 part of the resulting combustion gases firing an ammunition ( Figure 4).
- a return spring 182 returns the piston rod 175 to its position original after firing the ammunition.
- This external fire stop command 185 ( Figures 3 to 5) is fixed in rotation relative to the rotating assembly 100 and includes a movable sector 187 in translation which is intended to cooperate with a pawl 189 mounted pivoting about an axis 191 of the block rotary support 172 of the cylinders 177.
- This pawl 189 is positioned on the support block 172 so as to ability to cooperate with piston rod 175 by means of command 170 associated with one of the tubes T of the weapon.
- the pawl 189 ends with a hook 192.
- the firing stop sector 187 is controlled by a electromagnet 194.
- each control means 170 traverses right through the associated cylinder 178, but the piston rod 175 associated with the pawl 189 further comprises, a end, a flange 196 intended to cooperate with the hook 192 to be able to immobilize the piston rod 175.
- the trigger G is in position noted before the firing of a munition by one any of the T tubes, and the piston rods 175 of trigger means 170 of the trigger G are each in their neutral position or retracted position inside of their respective cylinders 178.
- the striker 25 associated with this tube is actuated and the ammunition loaded in this tube T is fired.
- Part of gas resulting from the firing of the ammunition is conveyed by the passage 180 to the cylinder 178 of the cylinder 177 associated with the tube T.
- the piston rod 175 housed in the cylinder 178 then moves axially to take a position active, with concomitant compression of sound return spring 182.
- the piston rod 175 will first come into contact with the boss 164 of lowering lever 155 to make pivot this lever 155, lower the trigger G and allow the heel 150 associated with the tube T to pass freely in front of trigger G (figure 7), then at contact of the bearing surface 169 of the cam 167 for raise trigger G before firing ammunition by the next tube.
- each weapon barrel fires ammunition with, after each shot, retraction of the trigger G to allow free passage of the heel 150 associated with the tube T which has just pulled ammunition, and repositioning the trigger in position raised before the next shot.
- Heel 150 of rotary sleeve 140 which is associated with the tube T therefore goes come into abutment against the trigger G of the stop device 145 maintained in the active position not retracted. So the rotary sleeve 140 is immobilized in rotation, as in the previous case following a shot defective ammunition ( Figure 6).
- immobilization in rotation of the rotary sleeve 140 drives the immobilizer 120 in rotation of the rotating assembly 100 of the weapon, and stopping the drive motor M.
- the roller holder 126 and the rotary block 100 of the weapon continue their rotational movement during from which the roller carrier 126 also moves in translation along the firing direction of the weapon by following movement of the rollers 135 in the grooves helical 137 of the sleeve 140 immobilized in rotation.
- the roller carrier 126 While moving, the roller carrier 126 is supported on the bottom wall 125 of the telescopic tube 124a, which has to compress the first stack of spring rings 122a, then the second stack of spring rings 122b which is supported on the plate fixed 130 carried by the central rod 104.
- the compression of the spring rings 122a and 122b has the effect of absorbing energy kinetics of the rotating assembly 100 of the weapon.
- the return force of the spring rings 122a and 122b becomes greater than the rotational driving force roller carrier 126, the latter and the assembly turning 100 of the weapon are driven in a direction of reverse rotation during which the roller carrier 126 also moves in translation in one direction opposite to that which caused compression spring rings 122a and 122b.
- the kinetic energy of the rotating assembly 100 during the rotational movement reverse is absorbed by the second stack of spring rings 122b which extend over a shorter length to that of the first stack of spring rings 122a.
- the second stack has greater stiffness because the kinetic energy to be absorbed is less important during the reverse rotation movement of the rotating assembly 100.
- the telescopic tubes 124a and 124b initially driven in translation by the roller carrier 126 perform a reverse translation movement.
- the second tube 124b is then immobilized following the support of its outer edge 132 against the fixed plate 130, then that the first tube 124a comes into contact with the sleeve 114 hitch 106 which will be able to move towards the rear a distance limited by the axial length lights 118 in which the fixed pins 116.
- the trigger G when the weapon is at rest, the trigger G is not in the retracted position, if although one of the heels 150 of the rotary sleeve 140 is found against the trigger G. At the start of the shot of a burst for example, it is therefore necessary to retract the trigger G of the stop device 145.
- the complementary retraction device 200 comprises a lever 202 which, towards one end or front end, extended by a lateral boss 204 of generally triangular shape in which is formed a guide light 206, of angled shape and which receives a fixed pin 208. At its front end, the lever 202 is extends axially by a stop 210 intended to come cooperate with a crankpin 212 carried by the cam control 167 of the device 165 for lifting the trigger G. The other end of lever 202 is articulated in 214 on the mobile assembly 216 of an electromagnet of command 218.
- the lever 202 moves towards the device stop 145 while being guided by the fixed pin 208 which is moves in the light 206. This displacement is such that the stop 210 of the lever 202 comes to bear on the crankpin 212 of the control cam 167 in order to make it pivot to retract the trigger G and thus release the heel 150 of the rotary sleeve 140 which becomes free in rotation.
- trigger G must be lowered after firing ammunition through a T tube to allow free passage of the heel 150 associated with this tube T, then raised before firing an ammunition through the next T tube.
- trigger G remains in raised position to form a stop when passage of the heel 150 and thus immobilize in rotation the sleeve 140 and cause the translational movement of the roller holder 126 for compression of the spring rings 122a and 122b of the damping device.
- trigger G is maintained lowered during normal weapon operation and is only relieved following a defective shot from a ammunition or external control actuation stop shooting to cause, as before, immobilization in rotation of the sleeve 140.
- the trigger G consists of a shaped flap generally rectangular, one side of which forms a stop and the opposite side of which is extended by a rod 250 which materializes the pivot axis of the trigger G, this axis being parallel to the axis of rotation of the assembly turning 100.
- the trigger G is mounted on a support of trigger 152 which faces the rotary sleeve 140 and which is fixed in rotation relative to the assembly turning 100 of the weapon.
- trigger G When trigger G is in its position lowered, it is received in a housing 253 of the support 152 and a spring 254 is mounted in the bottom of this housing 253 to facilitate the lifting of the trigger G (figure 12).
- This 255 device to lower the trigger G includes a swivel lever 257 mounted in a plane perpendicular to the rod 250 of the trigger G, that is to say in a plane perpendicular to the axis of rotation of the rotating assembly 100. More specifically, the lever 257 is mounted free to rotate towards the end of a shaft 259 and has, at one end, a notch 260 intended to cooperate with a crankpin 262 which is carried by a radial arm 264 secured to the rod 250 of trigger G. This pin 262 is parallel to the rod 250 and offset from it, for transform the pivoting movement of lever 257 into a rotational movement of rod 250 and do so switch the trigger G to the retracted position.
- the movement swivel lever 257 is secured from a member 265 for controlling the rotation of the shaft 259 which supports lever 257.
- the rotational movement of the shaft 259 is transmitted to the lever 257 by a spring 267 mounted coaxially with the shaft 259. More specifically, a end of the spring 267 is fixed to the shaft 259, then that its other end bears on lever 257. Thus, a rotation of the shaft 259 results in a pivoting movement at lever 257.
- the controller 265 is for example a electromagnet, of which the moving part 265a picks up support on an eccentric pin 269 fixed at the end of the tree 259 which is opposite to that which cooperates with the lever 257.
- a translational movement of the moving part 265a results in a movement of shaft rotation 259.
- This shaft 259 is mounted on a block of support 270 located near the trigger support 252, these two supports providing space E between them which is mounted the lowering device 255 of the trigger G.
- This support block 270 is fixed in rotation relative to the rotating assembly 100 of the weapon. Considering the firing direction of the weapon, the block of support 270 is located upstream of the support block 152 of the trigger G.
- the electromagnet 265 is located on the side of the support block 270 which is opposite the space E, and the shaft 259 extends parallel to the axis of rotation of the rotating assembly 100 of the weapon.
- Lever 257 which lowers the trigger G is an element of a TR linkage comprising two other levers 272 and 274 mounted in the extension of lever 257, i.e. in a plane perpendicular to the axis of rotation of the assembly turning 100.
- lever 257 is articulated at one end of the intermediate lever 272 around an axis 276.
- the other end of the lever intermediate 272 is articulated at one end of the lever 274 around a hinge pin 277, while the other end of lever 274 is articulated at a point fixed around an axis 278.
- This TR linkage constitutes a line broken, the geometry of which can be distorted in conditions which will be explained below to make rotate lever 257 in the opposite direction to that printed by family tree 259.
- a device 280 is also provided for immobilize the trigger G when it is in lowered position.
- This device 280 includes a lever pivoting 282, one end of which is articulated in a fixed point around an axis 284. The other end of the immobilizer lever 282 is intended to penetrate into a notch 285 formed in the radial arm 264 integral of the rod 250 of the trigger G (FIG. 11).
- This lever immobilizer 282 extends parallel to the TR linkage, and cooperates with a return spring (not shown) to hold lever 282 in its position of immobilization of the trigger G.
- the pivoting of this lever is controlled by a pin 287 which extends axially the hinge pin 277 provided between the two levers 272 and 274 of the linkage, as will be described later.
- a device 290 is also provided for raise trigger G.
- This device is also located in space E and includes a lever 292, one of which end is articulated at a fixed point around the axis 284.
- the other end of the lever 292 is intended to cooperate with a crankpin 295 for toggle trigger G.
- This 295 pin is supported by a radial arm 296 secured to the rod 250 of the trigger G.
- Crankpin 295 extends parallel to the rod 250, is offset and enters a hole 297 provided in lever 292.
- lever 292 of trigger release G is parallel to the TR linkage and immobilizer lever 282, and it has an opening 298 for the free passage of the trigger rod 250 G.
- the lever 292 has a boss 299 on which each of the means of action can act command 170 of the first embodiment, namely the piston rod 175 of cylinder 177 associated with each tube of the weapon and whose position is controlled by borrowing from gas from the ammunition fired by this tube T.
- the external fire control 300 includes a sector swivel 302 which is fixed in rotation relative to the rotating assembly 100 of the weapon.
- Sector 302 has a curved surface 302a forming a cam, and is mounted articulated on the side of the support block 270 which is opposite the space E where are mounted devices 255 and 290 to lower and raise trigger G. Specifically, one end of the sector 302 is articulated on an eccentric pin 304 carried by a radial arm 306 secured to the shaft of control 259 of the lowering lever 257. The other end of sector 302 is articulated on a crankpin eccentric 308 carried by a radial arm 310 secured to a shaft 312 rotatably supported by the support block 270 and extending parallel to the control shaft 259.
- the sector 302 can thus pivot in a plane perpendicular to the axis of rotation of the assembly turning 100, its surface 302a forming a cam facing this rotating assembly.
- Sector 302 can rotate between a rest position and a control position, knowing that a return spring 315 mounted coaxially with the control shaft 259 has one end which takes support on sector 302 so as to bring it back automatically in rest position when the electromagnet 265 for rotating the shaft 259 is not not excited.
- the external fire control 300 also includes a rotary distributor 318 mounted around one of the T tubes of the weapon and is described below with reference to Figure 10.
- This distributor 318 has an opening 320 which is intended to form a gas passage between the tube T and the cylinder 178 of the cylinder 177 associated with this tube to control movement piston rod 175 mounted in cylinder 178.
- This distributor 318 plays the role of the ratchet 189 of the first embodiment.
- Sector 302 is intended to modify the distributor position 318 to interrupt the connection between tube T and cylinder 178 of cylinder 177 when the external fire stop command 300 is actuated.
- the dispenser 318 has a heel radial 322, the free end of which then comes into contact of the cam 300a of sector 302 to rotate the distributor 318 around the tube T which supports it.
- the trigger G is in position lowered before firing ammunition by any one T tubes, and piston rod 175 of cylinder 177 associated with this tube is in an active position, i.e. that the piston rod 175 during the movement of rotation of tube T is likely to come into contact with the TR linkage of the lowering device 155 the trigger G and the boss 299 of the lifting lever 292 of the trigger G.
- the electromagnet 165 is kept supplied for that its 265a moving crew be supported on the crankpin of operation 269 of the tree 259 to force the latter to perform a rotational movement which is transmitted to the lever 257 of the TR linkage.
- Notch 260 of lever 257 thus comes into contact with the crankpin of maneuver 262 which rotates the rod 250 of the trigger G in a direction which tends to position the trigger G in its lowered position.
- Lever 282 of trigger immobilizer 280 G is then engaged in the notch 285 of the radial arm 264 which supports the crankpin 262 (figure 11).
- the firing stop sector 302 When the electromagnet 265 is activated, the firing stop sector 302 is in its rest position and the return spring 315 associated with sector 302 is at the bandaged state.
- the operation will be described taking into account only one single tube T of the weapon, the heel 150 of the sleeve 140 associated with this tube T and the control means 170, also associated with this tube T, to modify the trigger positioning G.
- the striker 25 associated with this tube is actuated and the ammunition loaded into this tube is fired. Part of gas resulting from the firing of the ammunition is conveyed by the opening 320 of the rotary distributor 318 in the cylinder 178 of cylinder 177 associated with tube T.
- the rod of piston 175 housed in cylinder 178 then moves axially to take a rest position, with setting in concomitant compression of its return spring 182. Under these conditions, during the rotational movement of the tube T, the piston rod 175 associated with this tube cannot come in contact with neither the TR linkage associated with trigger lowering device 255 G ni with the boss 299 of the lifting lever 292 of the trigger G.
- the heel 150 of the sleeve 140 which is associated with the tube T which has just fired a passing munition freely in front of trigger G, just like heel 150 associated with each tube T of the weapon which fires ammunition during a complete rotational movement of the assembly turning 100 of the weapon.
- the piston rod 175 comes in contact with the TR linkage near the axis 277 between the two levers 272 and 274. This contact has the effect of modifying the geometric line broken formed by the TR linkage and forces the lever 257 pivot so that its notch 260 emerges from the crankpin of actuation 262 of the trigger G. Simultaneously, the pawn 287 which extends this axis of articulation 277 is supported on the lever 282 so as to rotate the latter and release it from the notch 285 of the radial arm 264 secured to the rod 250 of the trigger G. In these conditions, trigger G is released from the device 255. Then the piston rod 175 comes in contact with the boss 299 of the lifting lever 292 which, via the shunt pin 295, causes the triggering of the trigger G in its raised position (figure 12).
- Trigger G is raised before the heel 150 of the sleeve 140 which is associated with the tube T does not pass in front of trigger G, so that heel 150 will come into abutment against the trigger G and cause the sleeve 140 to immobilize in rotation.
- the return spring 315 associated with the sector 302 can then relax and pass the sector 302 in its active position.
- heel 322 of distributor 318 will come into contact with cam 302a and thus force the distributor 318 to rotate around the tube T, so that the opening 320 of the distributor 318 no longer connects the T tube and the cylinder 178 of the cylinder 177 associated with this tube T (figure 13).
- a dysfunction in shooting a ammunition and actuation of the external stop command firing results in a rotation stop of the sleeve rotary 140.
- This rotation stop of the sleeve 140 drives the immobilizer 120 in rotation of the rotating assembly 100 of the weapon, in a manner identical to that described in the first embodiment.
- a counter-trigger 198 armed with a spring and supported by the support block 152 of the trigger G. This counter-trigger 198 comes to bear against the heel 150 of the sleeve 140 which precedes that blocked by the trigger G.
- This device 330 includes a element 332 movable in translation under the control of a screw 334 for example and which supports the axis hinge 277 of lever 274.
