Electrical equipment company m. B. H. in Berlin-Marienfelde. - Firing device for ship guns.

Patented in the German Reich on March 9, 1924.

There have already been proposed for launchers SchifFsgeschützc containing two contacts, one of which is in accordance with the rolling movements and flor other according to the Schliugergc- -chwindigkeit advantageously moved automatically. An eddy current tachometer, for example, is used as a control device for the latter of these contacts,
The subject matter of the invention is a firing device which achieves even greater accuracy and which is characterized by great simplicity and clarity of the arrangement. The Krrlnduns- essentially consists in the fact that the contact to be moved according to the slider speed is influenced by the electromotive force which arises in a coil moved according to the rolling movements in a magnetic field.

Details of the invention are to be explained in more detail with reference to the figures. Fig. R shows the entire device essentially in longitudinal section, while in Fig. 2 details are shown.

A circular housing is connected to a housing α which essentially accommodates the entire device.

cliem in bearings C ₁₃ C ₂ by means of pin Cf ₁ . d ₂ a circular ring is arranged. A bevel gear / which engages with a bevel gear g sits on the pin d _t. On the axis h of the Kcgel-S wheel g sits a spur gear i, which is in engagement with a spur gear I mounted on an axis k. A coil m is also arranged on the axis k , the ends of which are connected to the slip rings n _lt n " which are also located on this axis. The coil m is located between the "poles W ₁ and zv" of a direct current magnet system, which expediently generates a completely homogeneous field. Brushes O ₁ , 0,, slide with the ends of the coils _{on the rings M 1} , n p. of a moving coil device q . The device q is rigidly connected to the housing α in such a way that the axis of rotation of the pointer s lies in the extension of the axis k. At the tip of the pointer j, a contact t is provided, the mating contact u of which is firmly seated on the axis k by means of an arm ν. The effect \ veise of the device is the following: When in a corresponding manner, the direction of the cones Ci ₁ d "is set to 90 ⁰ to Schiffsachscnrichtung, tes vessel gyro rings moves in Schlingerbewegungcn (relative to my housing b where the pin rotates. Cl ₁ via the gearing f, g, i ₃ I accordingly the axis k and thus the coil sitting on it? ” An electromotive force is generated in the coil m which is directly proportional to the roll speed ₁ , n " and brushes O ₁ , o. _{2 influence} the coil /; of the measuring device q , and since the pointer axis r of this device is arranged centrally to the coil m , the deflection of the pointer s with its contact t also forms a measure The arm ν with the contact u , rotating with the axis k in accordance with the rolling movements, gives the position of the at every moment Ship again. The two contacts t and u are in the firing circuit for the guns. The nature of their movements can be seen in more detail in Fig. 2 in the view above. It is assumed that the ship is just at a turning point. The pointer s of the measuring device q is then in the XuIliage readable on the scale ν, since the coil m is not being rotated at this very moment. The arm ν, on the other hand, is exactly in one of the two reversal positions.! T ₁ , .r “. If I now move the ship back into the horizontal position, the contact ίί moves in the direction of the dashed arrow and the contact / in the direction of the fully drawn arrow. Depending on the severity of the rolling movements, the contacts meet at a greater or lesser distance from the Nu Hage and thus close the firing circuit. The "almost constant correction after the firing delay still required for the exact determination of the pre-ignition angle is expediently taken into account by regulating the excitation current of the magnetic field in which the coil m is arranged, or by a magnetic shunt, which is shown in Fig. R by a correspondingly shaped iron part 2 is indicated, which is rotatably arranged for example on pole ii '.
