Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a safety device for an externally powered gun having a barrel and a closure mechanism that is forcibly moved forward and backward and that is tightened in its forwardmost position.

In particular, the present invention is supported on a support so as to be freely movable backwards,
It has a gun chamber containing a rotating rotor that is moved from the front position to the rear position by recoil and to which a bundle of barrels is attached, and has a closing mechanism for each barrel, which closing mechanism is tightened by the barrel before the shot is fired. Pertains to safety devices for multi-barreled firearms such as

Devices of this type are known for interrupting the continuous firing of automatic high-velocity weapons of the Gattling machine gun type if a cartridge or cartridge is not withdrawn from the chamber of the barrel (German Published Application No.
(See No. 1809699). In this known device, there are means for preventing the delivery of cartridges into the cartridge chamber if, after rotation of the barrel bundle, there are still cartridges in the cartridge chamber which have not been drawn out. The means include a feeler member which prevents advancement of the closure device upon contact with an undrawn cartridge. For this purpose, a baffle piece is provided, which in a first position prevents the closing machine from advancing and in a second position
, the baffle piece being connected to the locating member.

A disadvantage of this known device is that it does not prevent premature unclamping of the closing mechanism in the event of a delayed ignition of the ammunition cartridge. That is, when the ignition is delayed, there is a risk that the propellant in the cartridge will be ignited after the closing mechanism is released. If the ammunition cartridge is ignited after the closure has been untightened, this results in the destruction of the main part of the gun and also puts the user of the gun at risk.

The problem to be solved by the present invention is to provide a safety device which reliably prevents the propellant of the ammunition cartridge from being ignited even after the closure mechanism has been released in the event of a delay in ignition.

Multi-barreled guns of the Gattling machine gun type have a bundle of barrels fixed to a rotor that rotates about the central axis of the bundle in the gun chamber. This rotor includes a guide track arranged longitudinally of the gun, i.e. a track for a closure machine attached to the gun barrel. By moving the closing machine forward on this guide track, the cartridge is first transferred into the gun barrel. After firing the ammunition cartridge, the empty cartridge is again withdrawn from the barrel by the closing machine and ejected, while the rotor rotates about its axis. In order to move the closures between the front clamping position and the position after which the empty cartridge is ejected, each closure is provided with a cam roller, which is arranged in an oval shape in the gun chamber in which said rotor is supported. Engages with the cam track. Furthermore, a feeding device is provided for feeding cartridges from the magazine into the gun chamber, where the cartridges are captured by a closing machine.
The oval cam track forces the closing machine to move forward and backward.

In order to solve the above problem, the safety device according to the present invention has the following features: the closing machine has a closing machine carrier and a closing machine head connected to each other, and the closing machine carrier is connected to a closing machine which is tightened by the gun barrel. A device is provided to release the weapon from the machine head, and this device responds to the delay in firing the ammunition cartridge.

This device can, for example, react in the absence of propellant gas pressure. In this case, a gas outlet is provided in the barrel, which allows the piston to be moved from the working position to the rest position by means of gas pressure. The piston is connected to the device, which prevents the closing mechanism from unclamping if the piston remains in the activated position during the firing delay.

The device can also respond in the absence of barrel recoil, for example due to forces produced by propellant gases, in which case the device responds either to a backward movement of the gun relative to a fixed support or to a subsequent forward movement.

In the first case, a cam plate is fixed to the gun chamber, and an inertial mass is movably attached to the closing mechanism, and this mass prevents the closing mechanism from unfastening if it remains in the operating position during firing delay. As a result, the recoil of the gun causes it to be displaced relative to the gun from the activated position to the non-activated position.

In the second case, a cam plate is fixed to the support, which cam plate is used when the gun is in the front position, in order to prevent unclamping of the closing mechanism when the gun moves from the rear position to the front during the firing delay. Sometimes engaged with a control device.

And finally, the device can also react in the absence of gas pressure in the cartridge. In this case, a recess is provided in the chamber of the gun barrel that accommodates the ammunition cartridge, into which the cartridge casing is pushed under gas pressure. A dosing pin protrudes into this recess, which is displaceable from its working position to its rest position. A control device is connected to the finder pin in order to prevent the closing mechanism from being unclamped if the pin remains in the operating position during the firing delay.

In order to solve the above problem, a gas extraction passage is further provided in the gun barrel to move the piston from the operating position to the rest position using gas pressure, and when the piston remains in the operating position, the closing mechanism is released. To prevent this, a control device is connected to the piston.

Next, embodiments of the present invention will be described in detail with reference to the drawings.

1-5 show a first embodiment of a safety device according to the invention. In FIG. 1, the Gattling machine gun has a barrel bundle 10 with six barrels 11, the rear end of which is fixed to a rotor 12. Barrel bundle 10
has a carrier 13 in front and is rotatably supported thereon. The rotor 12 is rotatably supported within the gun chamber 14. A toothed wheel 15 fixed to the rotor engages with a gearing 16 . The device 16 has five gears 17-
Including 21. The rotor 12 and the barrel bundle are driven by an electric motor (not shown) via a gearing 16. The gun chamber 14 mainly consists of two disc spring groups 2.
3 and 24. A feeding chamber 26 is fixed in the gun chamber 14 for feeding the ammunition cartridges 25, into which the ammunition cartridges 25 are conveyed in the direction of arrow A by an endless conveyor chain 27, and the empty chain 27 moves in the direction of arrow B. This leads to an ammunition container (not shown). Empty cartridge casing 28 is ejected from empty 26 in the direction of arrow C.

In FIG. 2, rotor 12 rotatably supported in gun chamber 14 has a guide track 29. In FIG. The closing machine 30 is movably supported between the two guide tracks. A cam roller 31 is fixed to each closing machine, which roller fits into a control groove 32. This control groove acts in such a way that the closing mechanism 30 moves back and forth once in the gun chamber 14 with one revolution of the rotor 12. As is known, when the closure device 30 moves forward, the cartridge 25 is pushed into the barrel 11, and when it moves backward, the empty cartridge 28 is pulled out of the barrel 11 and ejected. The closure device 30 is tightened in its forwardmost position before firing the bullet. As soon as the bullet is fired, the closure is unclamped.
Since the rotor 12 is driven by an electric motor, the closing machine 3
0's feeding, tightening, unclamping, and retraction are performed compulsorily.

However, if the cartridge 25 does not fire correctly, ie if the firing is delayed, it may happen that the closing mechanism 30 is already unclamped before the bullet is fired.

According to the present invention, a device is provided for preventing premature release of the closing mechanism in the event of a delayed ignition. This device will be described below.

In FIG. 3, the closing machine 30 is a closing machine carrier 33.
and a closing machine head 34, which are spaced apart from each other in FIG. This separation only occurs in the case of the firing delay described above.

The closure head 34 has ten clamping cams 35, some of which are shown in FIG. Rotation of the closing machine head causes these cams to move around the rotor 12.
Located at the rear inside. A clamping body 62 is displaceably mounted on the closing machine head 34 and has a screw-shaped projection 63 with a markedly inclined angle. Closing machine 3
As soon as the head 34 reaches its forward position during the zero advance, the clamping body 62 is displaced from the position shown in FIG. 3 to the position shown in FIG. Since the tightening body 62 is fixed to the closing machine head holder 64 and cannot rotate, the closing machine head 34 is rotated by the threaded projection 63 during the above-mentioned displacement, and is bayonet-fitted into the rotor 12 and tightened. This state of tightening is also shown in FIG.

In FIG. 5, the barrel 11, which is fixed to the rotor 12, has a chamber 36 for receiving an ammunition cartridge. At the front end of this chamber, near the mouth of the cartridge case 28, there is a gas outlet 37 which passes through a nozzle 38 to the gas passage 3.
Connects with 9. This passage opens into a gas chamber 40, in which a piston 41 is displaceably supported. There is a spring 42 on the piston 41, which rests on the bottom of the gas chamber 40 and is attached to the piston 41.
It has the role of displacing the body forward, that is, to the left in FIG. Piston 41 has a cam 43 for actuation of lever 44. However, due to gas pressure, the piston 41
As soon as the cam 43 is moved backwards against the force of the spring 42, to the right in FIG. 5, the cam 43 disengages the lever 44. This lever is double-armed and is supported in the gun chamber 14 so as to be able to swing around an axis 45, one arm 46 of which is connected to the cam 43 of the piston, and the other arm 47 to the second double-armed lever. Each is supported by 48. Second lever 48 (also shown in FIG. 7)
is swingably supported in the gun chamber 14 about an axis 49, one arm 50 of which is connected to the arm 47 of the first lever 44, and the other arm 51 is connected to the third double-armed lever 52.
Each is supported by The third lever 52 is the shaft 5
3 is swingably supported in the gun chamber 14,
One arm 54 is supported by an arm 51 of the second lever 48, and the other arm 55 is supported by a control lever 56, which lever 56 is supported swingably about an axis 57 in the closing machine head 34. Ru. This control lever moves the closure head 34 away from the closure carrier 33 as described below.

In FIG. 7, a first spring 58 is mounted in the gun chamber 14 and is supported on the arm 50 of the second lever 48 via a sleeve 59. A second spring 60 is mounted in the gun chamber 14 and rests on the arm 51 of the second lever 48 via the sleeve 61 and via the arm 54 of the third lever. These 2
The action of the two springs is to move the second lever 48 counterclockwise and also move the first lever 44 counterclockwise (sixth
), and the third lever 52 is to be swung clockwise.

In FIG. 5, the firing pin 65 is displaceably supported in the closure carrier 33. a spring 66 supported on the rear end of the firing pin on the one hand and on the shutter carrier 33 on the other hand;
has the role of protruding the firing pin toward the bottom of the cartridge 28. A driver 67 is fixed to the rear end of the firing pin 65, which cooperates with a cam disc, not shown, for the purpose of releasing the firing pin 65 to pierce the cartridge 25 at the most desirable moment.

8 and 9, the closing machine head retainer 64
is connected to the closure carrier 33 by two rods 68, 69. The retainer 64 is attached to these rods.
A bolt 70 rotatably supported therein is fixed. These bars are secured as shown by a frame 71, a cross-section of which is shown in FIG.
Two bolts 72 and 73 are fixed to the frame 71 (FIG. 8), and these bolts are attached to the closing machine head retainer 64.
It is rotatably supported inside. The frame 71 is secured by two levers 74 and 75 as shown,
These levers can swing around the bolt 76. The two levers 74, 75 have a cam 78 in one arm 77 which fits into a groove 79 in the frame 71. Further, a spring 81 is supported at both ends of the other arm 80 via a sleeve 108. The spring 81 is
The cams 78 of the levers 74 and 75 are inserted into the grooves 79 of the frame 71.
It thus serves to keep the frame in its secured position. The previously described control lever 56 (FIG. 5) serves to actuate the frame 71, which lever is pivotably mounted around a bolt 57. The control lever 56 (FIG. 10) is connected to the lever 5 by a first arm 82.
2 (also shown in FIGS. 5 and 6). Furthermore, the second arm 83 of the control lever is connected to the frame 71.
The third arm 85 is also pressed against the slider 87 by a spring 86.
A dosing pin 88 is fixed to the slider 87, and is pushed out by the spring 86 through the arm 85 to the bottom of the cartridge case 28 (FIG. 5). The second arm 83 of the control lever 56 moves into the frame 7 when two conditions are met.
It engages with the protrusion 84 of No. 1. One is that the closure machine head holder 64 must be in its forwardmost position shown in FIG. 5, and the other is that the cartridge 25 must be present.
Without the ammunition cartridge 25, the slider 87 together with the control lever 56 pivoted thereon would be moved forward by the spring 86, i.e. to the left in FIG.
does not engage with the protrusion 84 of the frame 71.

In FIG. 10, a pawl 89 is pivotally mounted on a shaft 90 in contact with the closing machine head holder 64. In FIG. This pawl has double arms and moves together with the cam 91, which is connected to the rotor 12.
is fixed to the guide track 29 of. One arm 92 of the claw 89 is supported by a protrusion 93 of the closing machine head 34,
The claws are attached to the tightening body 6 fixed to the retainer 64.
2 is prevented from being completely pushed into the closing machine head before reaching its forwardmost position. As soon as the other arm 94 of the pawl abuts the cam 91, the pawl 89 is rotated counterclockwise so that the one arm 92 of the pawl comes out of engagement with the projection 93. As the closing machine head retainer 64 returns, one arm 92 hits the cam 91, which causes the pawl 89 to rotate clockwise to its original starting position (FIG. 10).

In FIG. 14, the guide track 29 has a notch 109.
The arm 80 of the lever 74 can fit into it, thereby preventing the closure head 34 from advancing.

In FIGS. 2 and 15, the cartridge 25 is conveyed by a star wheel 95 to the front of the chamber closing device 30;
In that case, FIG. 15 shows only the cartridge, but not the closure device. These cartridges 25 are located at position E.
I was struck by the firing pin. When a firing delay occurs, the cartridge 25 is not pulled back from the gun barrel 11 and comes to position F due to the rotation of the rotor 12. At this point, the cartridge casing 28 remaining in the gun barrel 11 is probed by the probe pin 96. This pin is displaceably supported on the rotor 12 and is moved radially outward from the position shown. Two rods 97, 98 of the toggle device are supported on the dot pin 96, rod 97 is connected at its end 99 to the gun chamber 14, rod 98 is connected to the deflector piece 10 via a coupling 100.
1. The cylinder 10 is attached to the deflecting piece 101.
2 are connected, in which a spring-loaded piston is connected to the feed chamber 26 via a piston rod 103, and pressure acts on the deflecting piece 101 so that when the toggle device is actuated, the deflecting piece 101 is connected to the shaft 104. sway around. Due to this rocking, the ammunition package 25 that was being sent by the star wheel 95 in the direction of arrow A
is no longer sent to the gun chamber 14, but directly to the feed chamber 26.
It reaches into the discharge passage 105 of. The empty cartridge case 28 is moved to the adjacent case ejection channel 10 by the second star wheel 106.
Sent to 7.

The manner in which the safety device described above operates is as follows.

1, 2 and 15, cartridges 25 are fed into the feed chamber 26 in the direction of arrow A and into the gun chamber 14 by a star wheel 95. In FIGS. 2 cartridges of each cartridge in the gun chamber
5 is grabbed by the closing machine 30 and transferred into a suitable gun barrel. At this time, the rotor 12 moves in the direction of arrow P (15th
(Figure). At position E, the closure device 30 reaches its forward position under the action of the control groove 32 (FIG. 2) and the cam roller 31, where the cartridge is struck by the firing pin 65 (FIG. 5).

If the propellant in the cartridge 25 ignites at the correct time, the propellant gas enters the gas outlet 37 (FIG. 5) and reaches the chamber 40 through the gas passage 39, whereby the piston 41 is moved under the force of the spring 42. It resists and is displaced to the right (Fig. 5), that is, backward. Therefore, cam 4

The closure machine head 34 also retreats, and the cartridge case 28 is moved to the barrel 11.
drawn from. This empty cartridge case 28 is moved through the ejection channel 10 by the star wheel 106, as shown in FIG.
It is pushed out from 7.

However, if the propellant in the cartridge 25 is not ignited at the correct time by the firing pin 65, the propellant gas outlet 3
7, gas passage 39 and chamber 40. Therefore, the piston 41 will not be displaced to the right (FIG. 5) or rearward against the force of the spring 42. The cam 43 remains in the orbit of the double-arm lever 44. According to FIG. 6, the rotor 12 is connected to the gun chamber 14.
When rotating against the arm 4 of the lever 44, the cam 43
6, which causes the lever 44 to be turned clockwise. During this swinging, the lever 48 is rotated by the arm 47 of the lever 44, and therefore the lever 52 is also rotated counterclockwise by the arm 51 of the lever 48 (FIGS. 6 and 7). In Figure 5,
The control lever 56 of the closing machine 30 is connected to the arm 5 of the lever 52.
5 in a counterclockwise direction to reach the position shown in FIG. The arm 83 of the lever 56 then abuts against the projection 84 of the frame 71, and the frame is thus rotated into the position shown in FIG. Accordingly, the rods 68, 69 are swung out of the frame and into the position shown in FIG. When the obturator carrier 33 is retracted, the obturator head holder 64 remains in the forward position with the obturator head 34, and only the obturator carrier 33 is retracted to the position shown in FIG.

The above-mentioned separation of the closure head 34 from the closure carrier 33 occurs only in the event of a delay in firing, and not at the beginning of firing when the cartridge is not in position E (FIG. 15) in the barrel.

In FIG. 11, if the cartridge 25 is not present, the feeler pin 88 will move to the left and therefore the lever 56 will move to the left.
The arm 83 of is disengaged from the projection 84 of the frame 71. In this case, therefore, the detachment of the closing machine head 34 from the closing machine carrier 33 as shown in FIG. 3 cannot occur. It is further noted that in the absence of ammunition cartridge 25, i.e., when the feeler pin 88 is moved forward, the double-arm lever 56 also moves to the left (FIG. 11), thus causing the engagement of the double-arm lever 52 with the arm 55. This may or may not be the case. Without gas pressure and without an ammunition cartridge, lever 52 (FIG. 5) will indeed actuate, but it will not be able to swing control lever 56, since control lever 56 is shown in FIG. This is because the lever 52 is no longer engaged with the arm 55 of the lever 52.

In the case of delayed firing, the closing machine head 34 separated from the closing machine carrier 33 cannot be displaced further. By swinging the frame 71 to the positions shown in FIGS. 13 and 14, the two levers 74 and 75 can no longer be fitted into the grooves 79 of the frame 71 by the cam 78, and are moved by the spring 81 to the position shown in FIG. be passed around. At this time, the arms 80 of the levers 74, 75 reach into the recesses 94 of the guide track 29, thereby preventing displacement of the closing machine head 34.

When rotor 12 rotates in the direction of arrow P (FIG. 15), cartridge 25, which is not fired at position E due to the ignition delay, reaches position F. Since this cartridge was not withdrawn from the barrel as described above, it impinges on the dot pin 96, activating the toggle device and thus causing the deflector 101 to rotate about the shaft 104. Therefore, the fed ammunition cartridge is no longer in the gun chamber 14.
It does not reach the inside of the container but enters the discharge path 105. The feed to the gun is interrupted.

In FIG. 16, the gun barrel 211 is connected to the rotor 210.
Fixed. The rotor 210 is rotatable about an axis 212 and includes five barrels not shown in addition to the barrels shown. These six barrels are arranged parallel to the axis 212 and at equal intervals on the circumference. The rotor 210 is rotatably supported in the gun chamber 214 using a bearing 213. Gun chamber 214
is supported on a support 215 (how it is supported is not shown) and is movable for retraction of the gun. Support 215 is illustrated as a single line. The direction of movement of the gun relative to the support is indicated by arrow A. Support 2
A cam plate 216 (FIG. 17) is fixed to 15, and the cam plate projects into the gun chamber 214 through a hole 217.
The hole is large enough that the cam plate does not abut the edge of the hole during movement of the gun chamber 214. Inside the gun barrel 211 is a cartridge 218 . When firing a cartridge, the gun chamber 214
moves to the right from the position shown in FIG. Behind the barrel 211 is a closure 219, which has a closure head 220 and a closure carrier 221, the closure head 220 having a number of cams, of which two cams 222 are shown. This cam causes the closure head 220 to be bayoneted by rotation within the rotor 210 about the closure axis 223. This tightened position is the 16th
As shown in the figure. Closing machine carrier 221 is movably supported in rotor 210 on tracks 224 . A roller 225 is rotatably supported on the closure carrier 221 and is located in an oval groove 226 in the cylindrical gun chamber 214 . This groove allows the obturator carrier 221 to move forward and backward in the direction of arrow A during rotation of the rotor 210 about the axis 212 in the gun chamber. In FIG. 16, the closure carrier 221 is in the forward position with the closure head 220. Both of these are connected to each other in a manner not shown. A double-armed lever 227 serves to uncouple the obturator carrier 221 from the obturator head 220, which is pivoted on a shaft 228. This shaft is fixed via an arm 229 to a pin 230 which is displaceably supported in the closing machine head 220. Spring 23
1 forces the pin 230 into the bottom of the cartridge 218. The front end 232 of the double-arm lever 227 cooperates with the cam plate 216 fixed to the support 215 described above, but this cooperation occurs when the gun chamber 214 is in the position shown in FIG. It is also shown in Figure 17.
In FIG. 17, the cam plate 216 projects into the interior of the gun chamber 214 through the hole 217. As rotor 210 (FIG. 16) rotates about axis 212 within gun chamber 214, forward end 232 of double-armed lever 227
moves in the direction of arrow B.

The manner in which the safety device described above operates is as follows.

Guns with this safety shall fire continuously. Therefore, the rotor 210 is connected to the gun chamber 214.
Arrow B around the axis 212 (Fig. 17)
As shown in FIG. 16, the gun chamber 214 moves to the right with respect to the support to the extent that the front end 232 of the lever 227 is disengaged from the cam plate 216. do. Therefore, the cam plate 216 cannot actuate the lever 227 and the closure head 220 remains connected to the closure carrier 221. For each rotation of the rotor 210, the closing machine 219 makes one complete advance and retraction, in which case the empty cartridge is ejected before the subsequent cartridge 219 is moved forward and backward.
is transferred into the gun barrel 211. However, as soon as the cartridge is not properly fired due to the firing delay, the closure head 220 will no longer retract. Retraction of the closing machine head after an ignition delay is prevented in the following manner.

In the case of delayed firing, there is no recoil of the gun, and under the action of the preceding closing mechanism, the rear gun chamber 214 moves forward toward the support 215, that is, to the left in FIG. It moves until it engages with the cam plate 216. As shown in FIG. 17, when the rotor 210 rotates in the direction of arrow B, the lever 227
The front end 232 of is pushed radially inward according to the shape of the cam plate 216. The lever 227 is therefore turned counterclockwise about the shaft 228 (FIG. 16). In this way, the closing machine 219 split into two,
That is, the closure head 220 remains in its forwardmost position, and only the closure carrier 221 is moved back to the right, since the rollers 225 are guided in the grooves 226. If the cartridge 218 is later fired, it is ensured that the closure head 220 is still in its forward, clamped position. As soon as the closing machine 219 separates into two, the gun is deactivated by a device not shown and the rotor 210 stops.

The second embodiment of the apparatus shown in FIGS. 18 and 21 differs from that shown in FIGS. 16 and 17 mainly in the following points. That is, the cam plate 216 is
It is fixed to the gun chamber 214 instead of to the gun chamber 15. Therefore,
There is no need to provide holes in the gun chamber for the cam plate 216 to pass through. When the gun is retracted, the cam plate 216 also moves in the direction of arrow A.

It is fixed at 37. Pin 237 is the closing machine head 2
20 so as to be freely displaceable. Spring 241 forces pin 237 against the bottom of cartridge 218. There is a pin 239 in the hole 238 of the double-armed lever 233, which is pressed against the arm 236 by a spring 240, so that the lever 233 is moved to the right (first

It is located at 6. The shape of the cam plate 216 is the 21st
As shown, it is the same as the cam plate 216 of FIG. 17. As shown in Figures 18 and 21,

The operation of this second embodiment is as follows.

In this case as well, the gun with this safety device shall fire continuously. The rotor 210 is the gun chamber 214

1), the gun chamber 214 moves to the right with respect to the support 215 under the action of the recoil as shown in FIG. The lever 233 remains in the starting position due to its inertia and therefore moves to the left relative to the closing machine head 220 so that the end 242 of the lever is in the closing position 242.

Every 10 revolutions, the closing mechanism 219 advances and retracts once completely, with a new cartridge 218 being inserted into the barrel 21.
1, after the empty cartridge of the preceding cartridge has been ejected. However, as soon as cartridge 218 is not properly fired due to firing delay, closure head 220 is no longer retracted. This regression is prevented as follows.

In the case of delayed firing, there is no recoil of the gun, and the previously described relative movement of the lever 233 with respect to the closing machine head 220 does not take place, so that the front end of the lever 242 is connected to the cam plate 2.

Cam plate 243 ensures that lever 233 is in its starting position (FIG. 18) before firing is made. However, when firing, the cam plate 243
It does not engage with the protrusion 244 of No. 3.

The third embodiment of the present safety device shown in FIGS. 19 and 20 has the following points:
This is different from the one shown in Figure 1.

A search pin 245 is displaceably supported by the rotor 210 with respect to each gun barrel 211, and two of the search pins 245 are supported by the second pin.
0 and one is shown in FIG. Each dot pin 245 passes through a lateral hole 246 in the gun barrel 211 and is supported by a conical portion 247 of the cartridge case 248 . cartridge 2
It is in room 249 of 48. This room is search pin 2
45 has a hole 250 which prevents the cartridge case 248 from hitting the wall of the chamber 249, so that there is a space between the cartridge case and the chamber. When the ammunition cartridge is fired, the cartridge is expanded by gas pressure and is forced into the hole 250. At this time, the search pin 245 protruding into the hole 250 is displaced. In FIG. 20, the search pin 245 is pivotally attached to a double-armed lever 251, which is supported in a rotor so as to be swingable about an axis 252.

A spring 25 is attached to each lever 251 in the rotor 210.
3, this spring tends to turn lever 251 counterclockwise (FIG. 20) and forces dowel pin 245 into bore 250 of cartridge cone 247.
try to force it on The swinging movement of the lever is limited by a projection 254 on its left arm. A cam 255 is arranged on the right arm of the lever 251, which cam cooperates with a slider 256 shown in FIG. Slider 256 is axially slidably supported within gun chamber 214 . This slider is cam 255
19, the slider is moved to the left in FIG. The slider 256 has a cam plate 2 on the right end.
57, which cam plate is similar to the cam plate 216 and coacts with a lever 227, which has already been described in the case of FIGS. 18 and 21. The slider 256 is slidable from the right position to the left position by the cam 255 of the lever 251. Spring 2
58 attempts to keep slider 256 in its right position. Regarding closing machine 219, the first
Since FIG. 6 has been described, a detailed description thereof will not be given here.

The operation of the third embodiment of the safety device according to FIGS. 19 and 20 is as follows.

In this case as well, the gun shall fire continuously. Therefore, rotor 210 rotates about axis 212 within gun chamber 214 in the direction of arrow B (FIG. 20). During firing, the cartridge 248 is expanded by the gas pressure in the conical section 247 and the dolly pin 245 is displaced radially outwards (FIG. 20), with the lever 251 turned clockwise and shown in phantom. reach the desired position. The cam 255 is therefore turned radially inward, and this is done against the force of the spring 253. Therefore, the cam 255 is connected to the slider 2
56 and the slider is thus also held in the right position by the force of spring 258. The lever 227 is not actuated and the closure head 220 is not released from the closure carrier 221. On the other hand, if an ignition delay occurs, the search pin 245 remains at the position shown, and the lever 251 does not swing. Therefore,
The cam 255 remains at the slide 256 and displaces it to the left, so that the cam plate 257 reaches into the area of the lever 227. Lever left end 24
As soon as the lever 22 hits the cam plate 257, the lever 22
7 is turned counterclockwise, the closing mechanism 219 is disassembled, i.e. the closing mechanism carrier 221 is moved from the closing mechanism head 2.
Separated from 20.

In FIG. 22, six barrels 111 are normally removably mounted within rotor 110, only two of which are shown. The rotor 110 has a bearing 11
2 is rotatably supported in the gun chamber 113.
A closing device 114 is attached to each barrel, and the closing device is movably supported on a longitudinal guide track 115 in the rotor.
One closure 114 is in its forwardmost clamping position and the other closure is in its rearmost unclamping position. Each closing machine has a closing machine head 116 and a closing machine head holder 117, both of which together form a known rotary closing machine, i.e. the closing machine head 116 is connected to the closing machine head via a tall thread 118. It is connected to the retainer 117. The cam 119 of the closing machine head 116 engages the bore 12 of the rotor 110 when the closing machine 114 is tightened to its forwardmost position.
0 is fitted. The closure 114 further includes a spring-loaded firing pin 121 which can strike a cartridge 122 in the barrel in the forward clamping position of the closure. Furthermore, the closing machine 114 is a cam roller 1
23, which roller fits into a first control groove 124 in the gun chamber 113. This control groove allows the individual closures 114 to be moved forward and backward as the rotor 110 rotates. Control groove 12
4 has an oval shape and is arranged inside the gun chamber 113 which is approximately cylindrical. Second and third control grooves 125 and 126 are provided at the front and rear ends of the gun chamber 113, respectively,
These are arranged in a circle inside the gun chamber 113.
The cam roller 123 is connected to the control groove 125 or 126.
When engaged, there is no movement of the closure 114 as the rotor 110 rotates. When the cam roller 123 is in the control groove 125, the closure 114 remains in its foremost position, and when the roller is in the control groove 126, the closure 114 remains in its last position.
Deflectors 127, 128 are provided so that the cam roller 123 can reach one of the control grooves 125 or 126 from the oval control groove 124.

In FIG. 26, deflecting pieces 127, 128 are supported around a shaft 129 so as to be swingable. The cam roller 123 moves in the direction of arrow S in the control groove 124. In the illustrated position of the baffle, the cam roller 123 always remains in the oval control groove 124. The following elements serve to activate the baffle.

In FIG. 22, each barrel 111 has a gas outlet 130 from which the driving gas enters a gas chamber 132 via a passage 131. A piston 133 is located in this gas chamber, and the piston reaches the position shown in the figure under gas pressure. The piston 133 has a cam 134 which cooperates with a cam 135 of a blocking lever 136. This lever has a spring 137 which tends to force the cam 135 of the blocking lever against the cam 134 of the piston. The blocking lever is pivotably supported around an axis 138. 26th
As shown, the blocking lever 136 fits into the hole 139 in the baffle piece 127 to prevent the baffle piece from swinging from the position shown.

A second blocking lever 140 is swingably supported in the gun chamber 113 about a shaft 141 so that the deflecting piece cannot swing from the illustrated position in the absence of an ammunition cartridge. This lever has a first arm 142 which probes for the presence of an ammunition cartridge 122. When the ammunition cartridge 122 hits the arm 142 (FIG. 24), the blocking lever 1
40 swings until its second arm 143 disengages from the baffle 127, so that the baffle is free to swing. Second search lever 144
is pivotally attached to rod 145, which serves to detect a cartridge that has been pierced. A pawl 146 is fixed to the other end of a rod 145 supported in the gun chamber 113, which pawl, in the position shown in FIG.
This prevents the deflecting piece 128 from swinging. gun barrel 1
If the cartridge 122 remains stuck in the cartridge 11, the rotation of the rotor 110 turns the probe lever 144, and therefore the pawl 146 via the rod 145, so that the deflector 128 is free. Become.

An actuating lever 147 is fixed to the firing pin 121, which lever cooperates with a control groove, not shown. This control groove is for opening the firing pin 121 and striking the cartridge 122 at the correct time.

The third embodiment of the safety device according to the invention according to FIG. 23 differs from the second embodiment according to FIG. 22 mainly in the following points. In FIG. 23, a cam roller 148 is attached to the closing machine 114 so as to be movable in the axial direction. Spring 149 tends to displace cam roller 148 radially outward. The two circular control grooves 124 are deeper than the two circular control grooves 125 and 126. As long as the cam roller 148 is pressed against the bottom of the control groove 124 by the spring 149, the cam roller will remain in the control groove. In order for the cam roller 148 to be able to reach either of the circular control grooves, it must be moved radially inward against the force of the spring 149. No baffle piece is required to divert the cam roller 148 from the control groove 124 to one of the control grooves 125,126. The configuration of the device for radial movement of the cam roller described above is as follows.

The actuating lever 150 shown in FIG. 23 cooperates with the piston 133 already mentioned in FIG. It hits the cam 134 of the piston. Actuation lever 1
A pawl 152 provided at 50 is pivotally mounted on a shaft 153, and this pawl cooperates with a double-armed pawl 154. The claw 154 has a first arm 155 (FIG. 24), which arm
52, and the pawl 154 engages the second arm 156.
, and this arm cooperates with a cam roller 148.
The pawl 154 is swingably supported in the gun chamber 133 about a shaft 164. The claw 152 is the blocking lever 15
7, the pawl 154 can be operated only when it is positioned downward. The blocking lever 157 is located in the gun chamber 1.
33 so as to be swingably supported around a shaft 158. The blocking lever 157 probes the cartridge 122 as shown in FIG. If a cartridge 122 is present, the blocking lever 157 reaches the position shown;
The pawl 152 (FIG. 23) is therefore positioned downwardly.

A feeler lever 144, which serves to detect a cartridge that remains pierced, is fixed to a rod 145 supported in the gun chamber 133. Cam 159 (second
5) is fixed, and this cam is attached to the claw 160.
Insert into 1. This pawl is attached to the shaft 16 in the gun chamber 133.
3, and has an arm 162 outside the fork. The arm 162 is the closing machine 114
cam roller 148. As shown in FIG. 25, in the case of a cartridge 122 that remains pierced, this will turn the feeler lever 144 clockwise, which will also turn the cam 159 in the same direction, and the pawl 160 will turn counterclockwise. It's passed around. Claw 16
0 swing causes the cam roller 148 to release the spring 149.
(Figure 23) It is moved against the force.

The operation of the two embodiments shown in Figures 22-26 is as follows.

Upon rotation of the rotor 110 in the counterclockwise direction (indicated by arrow S), the closing device 114 closes the cam roller 1
23 or 148 is guided in the oval control groove 124, so that it always moves forward and backward. In this case of advancement, the cartridge 122, shown in dashed lines,
1 and the closing machine head 116 is moved into the rotor 11.
It is tightened during 0. At the same time, an ammunition cartridge 122a is fed to the closing machine 114a at the rearmost position from a feeding device (not shown). The cartridge 122 that has been fed into the barrel is closed after the closure head 116 is tightened.
The firing pin 121 ignites. At that time, the driving gas is
The gas enters through the gas outlet 130 and reaches the gas chamber 132 through the gas passage 131, so that the piston 1
33 is moved backwards, ie to the right in FIG. As the rotor 110 rotates, the co-rotating piston 133 is unable to place its cam 134 against the cam 135 of the blocking lever 136, so that the blocking lever 136 is not actuated.

If the ammunition cartridge 122 ignites with a certain delay or does not ignite at all, there is no gas mentioned above entering the chamber 132 and the piston 133 does not move. Rotor 110
When the piston 133 rotates, the piston 133 rotates along with it.
The cam 134 of the blocking lever 136
5 and therefore the blocking lever is spring 13
It is turned against the force of 7. Therefore, the blocking lever 136 disengages from the projection 139 of the baffle piece 127, so that the baffle piece is no longer held. Cam roller 123 moving in the direction of arrow S
(FIG. 26) abuts against a baffle piece 127, which is thus rotated by a cam roller, the cam roller 123 passing from an oval control groove 124 into a circular control groove 125. The closing mechanism 114 is therefore no longer retracted and remains clamped in its forward position. The deflecting piece 127 is the blocking lever 13
During the next rotation, the closing devices 114 of the remaining five barrels also remain in the forward, tightened position and are no longer fired.

In the third embodiment (FIG. 23) the operation of the gun is different. If the cartridge fires with some delay or does not fire at all, the motive gas will not enter chamber 132 and piston 133 will not be moved. When the rotor 110 rotates, the piston 133 that is entrained is moved by its cam 13.
4 against the cam 151 of the operating lever 150,
As a result, the operating lever swings around the shaft 138, and the pawl 154 (FIG. 24) is rotated counterclockwise via the pawl 152 held by the blocking lever 157. At this time, the arm 156 of the claw 154 is connected to the rotor 110.
pushed towards the center of Closing machine 114 belonging to rotor 110 strikes its cam roller 148 against arm 156 and cam roller 148 is displaced radially inward against the force of spring 149. The cam roller 148 thus reaches from the oval control groove 124 to the circular, shallow control groove 125, so that the closing device 114 remains in its forward position. However, as soon as the rotor 110 rotates further, the actuating lever 1
50 is not supported by piston 134 in the rotor and is returned to its original position by spring 137. Therefore, the claw 154 also returns to its original position, and the remaining barrel 1
The 11 closing machines can move forward and backward. Therefore, firing can be continued with five of the six barrels 111, and the gun is prevented from being automatically stopped due to firing delay.
