Description

In the device for dropping bombs from aircraft, patent 314801 each of the hanging hooks for the bombs is held by a special electromagnet controlled out. Depressing a key will turn the electromagnets in turn switched on, which releases the suspension linkage. No electromagnet can be switched on here before the electromagnet in the circuit in front of it is switched off.

Here is. but it is still possible that a whole series of bombs will drop one after the other if the pushbutton switch is a small one While the toggle lever remains depressed as soon as the bomb has dropped is and the suspension rod turns over, is turned over by a tension spring and the Stream the way to the next dropping device releases. This continues until the switch is opened again and the release magnets are de-energized. In the device forming the subject of the invention, therefore, an

Ä5 direction taken, which the toggle lever holds in its position for so long even after the suspension rod has been turned over, how the release magnet is energized.

This locking of the switching lever is effected with the help of a locking device that consists of an auxiliary electromagnet, which simultaneously with the excitation of the Tripping magnet is excited and the Umpchaltkontakt holds in the initial position until the Switch is open again, which connects the power source with the trip magnet. Only when the push button switch is open does the switchover lever move into the contact position. This position is a preparatory one, because as long as the pushbutton switch is open, the second bomb cannot fall because the circuit between the battery and the release magnet is interrupted. Only when the The push button switch is pressed again and the circuit is closed, the release magnet of the next following ejection device is excited. So it's for every bomb to be dropped requires a special switch.

In the drawing, such a device is in two different embodiments Positions shown.

In the first embodiment (Fig. 1, ι a, ib, ic) an auxiliary electromagnet I _{1 is} placed parallel to the release magnet f \ , which is excited when the push button switch b is pressed at the same time with the release magnet f ₁ and has the task of the switch lever To hold Ci ₁ against the action of a tension spring in its initial position until the excitation of the two electromagnets f _x and I ₁ is canceled by releasing the pushbutton switch b located between the battery α and the line C _1. Only after this has happened can

For changeover switch d _{lt following} the action of the tension spring, go to contact Vi ₁ and enable the current to pass to the second ejection device. The second bomb can only fall after the button switch /; has been depressed again, whereupon the current from the battery a through the push button switch b via the line C ₁ , lever d _s , line C ₁ , lever '«/. ,, line c ₂ to the electromagnet f. , whose armature goes is attracted. As a result, the lever / i ₂ loses its support and releases the suspension hook i. For the bomb k. , So that it can fall off. As with the first ejection device, the switching lever is held by the auxiliary magnet L ₁ against the action of the spring as long as the pushbutton switch b remains depressed. If the pushbutton switch is returned to its initial position, the electromagnets are de-energized and the game described above is repeated the next time the switch is pressed.

If the dropping devices are to be made available again to pick up bombs, the individual lever systems must be brought one after the other by hand into the position in which the bombs can be hung _{on the suspension hooks J 1} , i _{2 .....}

In the second embodiment (Fig. 2, 2 a, 2 b, 2 c) the movement of the switch takes place from the armature of the tripping magnet, and when the push button switch b is closed, the armature exerts a pressure in its attracted sillage through an auxiliary device on the also attracted armature of the auxiliary serving as a changeover switch ektromagneten I ₁ and pushes it, after the two electromagnets have become de-energized, into its end position and thus against a fixed contact, so that when the push-button switch is pressed again, the electromagnets of the next following Away-

^ S throwing device are energized. In this improved embodiment, the drop linkage is guided back to a single lever which at the same time forms the suspension hook M ₁ for the bombs. In the loaded state, the suspension hook lies against the armature of the release magnet f ₁ and is thus prevented from turning over. When the pushbutton switch b is pressed down, the release magnet f _± and at the same time also the auxiliary electromagnet I ₁ receive current. and both tighten their anchors O ₁ and P ₁ . The armature P _1, which is formed as one-armed lever possesses a resilient tongue q _x against which a ₁ of the tripping magnet Z ₁ from the raised bolt Y ₁ pressed by the armature O, which the attempt has, the armature P ₁ against the action to press the energized auxiliary electromagnet against a fixed contact J _1. As a result of the attraction of the release magnet, the suspension hook M _{1 is} free and the bomb can fall. By tipping over the suspension hook M ₁ , a support t ₁ previously displaced by it can step under the armature O ₁ , causing the same after opening the pushbutton switch b on. Falling down is prevented. Once the two electromagnets _lt f I ₁ b by opening the switch de-energized, the armature P ₁ lets go of the auxiliary electromagnet I. ₁ But since the armature O _{1 of} the tripping magnet f ₁ and with it the bolt T ₁ carried by it cannot go down because the resilient support I _{1 has} entered its path, the armature / J _{1 of} the auxiliary electromagnet becomes the action of the resilient tongue following pressed against 8ό the fixed contact J ₁ , so that the next time the pushbutton ^{switch is} pressed, the current from the battery α can flow through the pushbutton switch b through the line C ₁ to the contact J ₁ over the line U ₁ to the second throwing device, where repeat the game described above.
