The subject of the invention is an electrical one intended for recoil guns operated leveling device, by means of which the gun barrel automatically from the fire in the loading position and vice versa can be transferred.

An exemplary embodiment of the invention is shown schematically in the drawing.

Fig. Ι shows a partially kept in section

ίο Side view of the parts in question of a barrel recoil gun with the entire Circuit;

FIGS. 2 to 5 are corresponding to FIG Representations with parts of the circuit.

The gun barrel A is slidably mounted in the cradle B. The latter rests with horizontal trunnions, one of which (b ¹ ) is reproduced in the drawing, in the carriage body C. A pointer D is arranged so that it can swing on the trunnion δ ^1. This pointer can be pivoted together with an arm d ¹ from a handwheel E by means of a worm e ¹ and a worm wheel engaging with it about the axis of the horizontal trunnion. On the carriage body C there is a degree arc c ¹ , on the graduation marks of which both the pointer D and a pointer b ² rigidly connected to the cradle B can play. If the pointers D and δ ^{2 play} on one and the same graduation of the degree arc c ¹ , the gun barrel has the same inclination as the pointer D. A carrier b ^{3 is} rigidly connected to the trunnion δ ^1. Four contact rails δ ⁴ , δ ⁵ , δ ⁶ , δ ⁷ are arranged in an isolated manner on this carrier. These contact rails are concentric to the axis of the horizontal trunnions. The lower part of the support ³ has a toothing δ ^{δ: 8,} with which a gear F is engaged. This gear wheel can be driven by an electric motor G by means of worm gear units. (For clarity, the motor G is indicated again in the circuit diagram.) The reproduced in Fig. 1 position of the individual parts located between the contact rails δ ^4, δ ⁶ and the contact rails δ ^6, δ ⁷ with little play areas each a triangular Contact piece d ² or c ² . The contact piece d ^% sits on the arm d ¹ , while the contact piece c ^{2 is arranged} on the mount body C. The contact pieces d ^% , c ² are arranged in insulated sleeves, they are under spring pressure and can oscillate about an axis d ^a or c ^3. In the vicinity of the ^{spaces between the contact rails δ 4} , δ ^Β and δ ^β , δ ⁷ , electric spark blowers δ ⁹ , δ ^{10 are} attached to the carrier δ ^3.

A switching lever h ^{1 is} connected to the hand crank H of the gun breech, which, when the breech is closed, conductively connects two contacts β ¹ , a ² attached to the base of the gun barrel A by means of a contact piece. When turning the crank H , the shift lever h ¹ slides with two further contact pieces over two pairs of contact rails α ³ , α ⁴ , which are also arranged on the base of the gun barrel.

At the bottom of the gun barrel is

Furthermore, a contact piece a ^{s is} attached, which comes into contact with a contact piece δ ¹¹ resiliently arranged on the cradle B when the gun barrel returns.
Finally, an electromagnetic firing device / equipped with a pot magnet is built into the base of the gun barrel. The winding of the pot magnet is denoted by i ^1.

ίο The device also includes two electromagnetic relays. One is a double relay and consists of the coils K, M and the anchors N, P. With each of these armature is connected a transverse web on which the contact pieces n ^{1, n%,} n ^3, n *, n ^B, n ^e or .ft ¹ , ft ² , ft ³ , ft ^, ft ⁵ , ft ^{6 are} insulated. When the armatures N, P move apart, the contact pieces n ¹ , n ² , n ³ , n ^{A come} with fixed contact pieces n ⁷ , n ⁸ , n ⁹ , n ¹⁰ and the contact pieces ft ¹ , ft ² , ft ³ , ft * with them fixed contact pieces p ⁷ , p ^s , p ⁹ , ft ¹⁰ for touching, while when the armature N, P come together, brought about by a tension spring, the contact pieces n ⁶ , p ⁵ and w ⁶ , p ⁶ touch each other. ^{Electromagnets 11 are} attached between the aforementioned crossbars, which are intended to prevent vibration when the relay jumps into the middle position.

The second relay consists of the coil Q and the armature R with a transverse web, on which the contact pieces r ¹ , r ² , r ³ , r ⁴ , r ⁶ , r ⁶ , r ^{7 are} insulated. Depending on the position of the armature R, these contact pieces come either with fixed contact pieces r ^7x , r ⁸ , r ⁹ , r ¹⁰ , r ¹¹ , r ¹² or with fixed contact pieces ■ ylZ yl4: γΧ

r ¹⁷ , r ¹⁸ to the touch.

The individual parts are connected to a power source S ⁺ S ^- and to each other by cables in the following way:

^{The spark blowers δ 9} , δ ¹⁰ are connected in series by lines 1, 2, 3, 4 to the power source 5+ S ~, so they are constantly in action. Lines 5 and 6 lead from line 1 to triangular contacts c ² and d ² . From the line 1, a line 7 also leads to the contact piece a ¹ , which is connected to the contact piece r ⁹ for the relay armature R through a line 8. The contact ^{rails δ 4} , δ ⁵ are each connected to one rail of the contact rail pairs a ³ , ⁴ by wires 9, 10. Lines 11, 12 lead from the other rail of these rail pairs to the contact pieces r ¹³ , r ^ls . The contact bars δ ⁶ , δ ⁷ are connected to the contact pieces r ¹² , r ^7x for the relay armature R by wires 13, 14. The contact piece α ² is connected to the coil i ^{1 of} the firing magnet /. The coil i is connected to the contact piece ft ⁵ for the relay armature P through the line 15. An off switch T is switched on in line 15. A wire 16 leads from the contact piece « ^{2 to the contact δ 11} . The contact a ⁵ is through the line 17 with the coil Q in connection; this is through lines 18, 19 with the contacts n ⁸ and with the. Pole S ~ of the power source connected. The contacts n ¹⁰ and ft ¹⁰ are also connected to the pole S ⁺ by a line 20, and the coils K, M and the contact n ° are connected to the pole S ~ by lines 21, 22. Lines 23, 24 lead from the other ends of the coils K ₁ M ^{to the contacts r 14} , r ¹⁷ . A regulating resistor U is also connected to the pole S ~ of the power source, the other side of which is connected by a line 25 to the contacts n ⁷ and ft \ . Finally, the contacts n ² n ³ , ft ² p ³ , n ^s p ^% , n ⁹ ft ⁹ , ft * ft ⁶ , η ¹ ft *, ft ¹ w ⁴ , r ² r ³ , _r & _r i4 _(f n _r n connected in pairs by wires. A line 26 leads from the contact piece ft ⁹ to the contact r ^10. The armature G of the electric motor lies directly on the contacts n ^l and ft *, while the field winding g ¹ and a resistor V are connected to the power source S. ⁺ S ~ . From the ends of the resistor V , wires 27, 28 lead to the contact pieces r ¹⁵ , r ¹⁶ .

Once the pointer D from the shown in Figure 1 rest position, which the balance right location -. The loading position - corresponds the gun barrel speaks go, is pivoted by means of the handwheel E down, the contact piece passes d ^2, which is where the movement of the pointer D following arms d ¹ is seated, initially for contact with the rail δ ⁵ (Fig. 2). In the further course of the movement of the pointer D , the contact piece d ² rotates about its axis d ³ and rubs against the rail δ ⁵ . A circuit S ~ ^h -x-6-d ² -b ⁵ -io-a ⁱ -i2-r ^ls -r ⁷ -r ¹⁷ -24-M-22-21-S - is thereby closed, which results in has that the coil M attracts the armature P. This completes a new circuit 5 ⁺ -20- ^) ¹⁰ - ^ ⁴ -Gw ⁴ - ^ ¹ - ft ⁷ -2 $ -US ~ . The motor G, whose field winding g ^{1 is} constantly fed by the current source 5+ S ~~, the resistor V being short-circuited by the contact pieces r ^1B , r ^e , r ^le , now begins to rotate. Here, the motor pivots by means of the gear F and the toothing δ ^8, the carrier b ³ and with this the. Cradle B and the gun barrel A so long around the trunnion axis in the direction of the arrow χ (Fig. 2) until the contact piece d ² jumps back into the space between the rails δ ⁴ and δ ^5. The occurrence of interruption sparks between the contact piece d ^% and the rail δ ⁶ is prevented by the spark blower δ ⁹ , so that the circuit of the relay coil M is definitely interrupted as soon as the contact between d ²

and δ ⁵ ends. As a result, the coil M lets go of the armature P, which jumps into the central position under the action of the spring attached between the transverse webs of the armature P and N (FIG. 3). As a result, the armature G of the electric motor is immediately switched off from the power source S + S ~ and short-circuited by the electromagnet n ^11. The countercurrent generated by the motor armature G now causes the coils of the electromagnets n ^{11 to be} excited and the magnets are firmly attracted, so that the armature P is prevented from vibrating. -

At the end of the processes just described, the pointer δ ² attached to the cradle B is exactly opposite that graduation of the arc c ¹ to which the pointer D is set. The gun barrel has thus received the increase corresponding to the setting of the pointer D.

The contact piece c ² seated on the carriage body C came into contact with the rail δ ⁷ during the described movement of the carrier δ ³ and was rotated by this about the axis c ³ without initially closing a circuit. When the armature P jumps into the middle position, the contacts n ⁵ , p ^{5 have} come into contact with one another, so that since the switch h ¹ connects the contacts a ¹ , a ^% when the locks are closed, a circuit is created when the switch T is closed 5 + -i-7- « ¹ -Ä ¹ -a ² -i ¹ -i5-r-i5- /) ^B -« ⁵ -2i-S- can be formed. As soon as the switch T is closed, the coil i ^{1 of} the firing magnet / is energized and the gun is fired. If the switch T is closed before the movement of the gun barrel has ended, the gun is automatically fired at the Gun barrel. has received the desired setting. This is because at this moment the relay armature P jumps into the middle position, with the contacts ft ⁵ , p ^{5 of} the firing circuit being closed at the same time.

After firing, the gun barrel A runs back in the cradle B (see. Fig. 4). In this figure, the gun barrel has a larger elevation than in Fig. 3. When the gun barrel returns, the contact piece a ⁵ comes into contact with the contacts δ ^{11 of} the cradle B , so that a circuit S ⁺ -xya ¹ -h ¹ -a ² - i6-ö ¹¹ -e ⁵ -i7- <2-i9-2i-S "closed, so the relay armature R is attracted. Since - as mentioned above - the contact piece c ^{2 has} come into contact with the ^{curved rail δ 7,} So now, a second circuit S + -x-5-c ² -b ' ³ -X4-r' ^7x -r ¹ -r ⁸ -r ^li -23-K-2i-S- is closed.

. The excitation of the coil K causes the relay armature N to be attracted; this closes a third circuit 5 + -2O-w ¹⁰ -w ⁴ -G- ^ ^4: -m ¹ -w ⁷ ^ 25-17-S ~. The electric motor G therefore rotates, but in the opposite sense as at first, that is, by means of the gear F and the toothing δ ⁸ , it moves the carrier δ ³ and the cradle B connected to it as well as the gun barrel A in the direction of arrow y (Fig . 4). The contacts a ⁵ and δ ¹¹ touch each other only for a very short time, since the gun barrel moves forward again immediately after the return has ended. However, this short time is sufficient to excite the coils Q, K. The excitation of these coils causes the armatures R, N to be attracted. The latter creates a circuit 5 + -i-7- « ¹ -8-r ⁹ -r ² - r ^{s .r 10} -26-p ⁹ -n ⁹ -n ^a -n ² -n ⁸ -i8-Q- xg-2i-S ~ closed (Fig. 5), the existence of which is independent of the contact between the two contacts a ⁵ and δ ^{11 closed by the return.} The circuit just mentioned is also independent of the switch h ¹ connected to the lock crank H , so the lock can be opened immediately after the gun barrel has advanced without the circuit for the motor armature being interrupted. When the contact r ¹⁵ , r ^e , r ^le is opened when the relay armature R is pulled in, the resistor F, which has been short-circuited up to that point, is switched into the shunt circuit of the field winding g ¹ , so that the motor, as a result of the weakening of its field excitation, is switched on when the gun barrel is moved into the loading position , immediately adopts the fastest gear. The gun barrel continues its movement until the contact piece c ² jumps into the space between the rails δ ⁶ and δ ⁷ and the flow circuit passing through the relay coil K is thereby interrupted. The gun barrel then has the horizontal position again, ie it is in the loading position. The spark formation when the contact c ² slides off the rail δ ⁷ is prevented by the spark blower δ ¹⁰ ; After the coil K has become de-energized, it releases the armature N , which jumps into the middle position and thereby disconnects the motor armature G from the power source S ⁺ 5 -. At the same time, the circuit leading via the relay coil Q is also interrupted, so that the armature R is also released.

When the gun barrel A is moved into the loading position, the contact piece d ² comes into contact with the contact rail δ ^{5 again} , since the carrier δ ³ follows the movement of the gun barrel and the arm d ¹ with the pointer D in the initial, desired elevation of the gun barrel corresponding position remains. If the breech is now closed again after the gun has been loaded,

Thus, by means of the switching lever h ¹ connected to the crank H , first the rails of the contact rail pairs a ³ and ⁴ and then the contact pieces a ¹ and a ^{2 are} conductively connected. Due to the contact closure α ⁴ , the circuit S ^Jr -x-6-d ² -b ⁵ -xo-a ⁱ -i2- r ^ls -r ⁷ -r ¹⁷ -2 ^ -M-22-2i-S is again as at the beginning ~ closed, the relay armature P is attracted and thereby closes the electrical circuit leading through the motor armature.

ίο The motor then leads the gun barrel back to the increase corresponding to the setting of the pointer D.

If the pointer is pivoted upwards from the middle position shown in FIG. 1, a process similar to the process described takes place. Here, the contact piece d ² comes into contact with the contact ^{rail δ 4} , whereby the circuit S + -1-6-i ² -6 ⁴ -9- (j; ³ -ii-y ¹³ -r ^s -f ¹⁴ -23-if -2i-S "is closed. The armature η is attracted and closes the ^{motor armature circuit 5 + -20-m 10} -« ⁴ -G - /> ⁴ - n ^x -n ⁷ -2 $ - US ~. After setting the gun barrel A , the contact piece d ² jumps into the space between the contact rails δ ⁴ and δ ⁵ , the relay circuit is interrupted; the armature N jumps to the middle position, interrupts the motor armature circuit and at the same time closes the firing current.

When returning, the circuit S " ¹ " -1-7- α ¹ - /} ¹ - « ² -i6- δ ¹¹ - a ^& -iy-Q - 19 - 21 - S ~ is closed and the armature R is tightened. Then the circuits 5 + -i-5-c ² -ö ⁶ -i3-r ¹² -f ⁴ - r ¹¹ -r ¹⁷ -24-M-22-2i-S ~ and S + -2O- ^ ¹⁰ - ^ ⁴ -Gw ⁴ - p ¹ -p ⁷ -25-US " and immediately afterwards the current
