Telescope device in which, when the telescope carrier moves, the sighting direction is kept constantly in the same direction by means of a gyroscope device.

Patented in the German Empire on December 14, 1916.

The invention relates to such telescope devices, in which when moving of the telescope carrier, the sighting direction is continuously rectified by means of a gyroscope device is held. The invention aims to provide a device of this type in which the from the gyroscopic device to Determining the direction of sight to be transmitted forces can be kept very low and accordingly ensures that the gyro device works as error-free as possible. This purpose is achieved according to the invention in that of the two the direction of sight defining elements (target mark and ■. · Objectively) the one opposite. the telescope body at right angles to the optical axis straight

is linearly displaceable and connected to a gyroscope device in such a way that the sighting direction remains permanently in the same direction when the telescope carrier is moved.
In the drawing, exemplary embodiments of the subject matter of the invention are shown.

Fig. Ι and 2 show a device formed according to the invention in a periscope of a submarine, which is intended to change the direction of sight when the To keep the submarine in the same direction at all times.

Figs. 3 and 4 show a horizontally mounted telescope with the device according to the invention represent.

The example shown in Figs. 1 and 2 provides a movable target while in the example according to dsn Fig. 3 and 4, the lens is set up to be displaceable.

In particular, Fig. 1 shows a view directed towards the eyepiece part of the periscope, of which individual parts are broken away or kept in cut. '

Fig. 2 is a section along the line AB of Fig. 1, seen from above.

Fig. 3 is a side view of the horizontally stored telescope, in which the for the Movement of the lens provided organs are shown in section.

Fig. 4 is a section and partial view along the line CD of Fig. 3,

With ι is the housing of a submarine tube and with 2 denotes its eyepiece. On the bottom 3 of the housing 1 is a receiver motor 4 stored, which is located outside of the 'housing (not shown) Gyro-compass device is inevitably connected by electrical means, so that its armature shaft 5 is set in rotation when changes in direction of the boat and with it the periscope to that in the room stabilized by the gyrocompass device Enter the compass rose of the same. The rotation of the armature shaft 5 is consequently in direct dependence on the change of direction of the boat.

Each rotation of the armature shaft 5 is through a gear 6 fixed on the same on a Transferred crown wheel 17, the upright mounted on the motor housing at the lower end Wave 8 is seated. The shaft 8 is through a bevel gear 9 with a horizontal intermediate shaft 10 connected, which in turn by a pair of bevel gears 11, 12 with two also dare, right under parallel screw spindles 13, 14 are in positive connection. As well as the intermediate shaft 10 as well as the screw

• bspindles 13, 14 are shown in the drawing apparent. Way stored inside the periscope housing. On each of the screws spindles 13. 14 is a nut 15, 16 displaceable, but not rotatable. To secure the nuts 15, 16 against a rotation is provided by two parallel to the screw spindles, also in the frame

j. guide pins 17, 18 arranged inside the house, on which the nuts 15, 16 lead through corresponding holes. Between An extremely fine wire 19 is attached to the two sliding screw nuts 15, 16 taut, which forms the target mark and the connection with the lens the Specifies the direction of sight. The direction of the wire 19 is chosen so that it is the observer appears in the periscope in an upright position. The plane in which the target mark is formed Wire 19 is displaceable, is at the same time

, Image plane of the periscope; therefore appear to the person looking at the target through the periscope Observer target and sighting mark equally sharp and parallax-free .. As the sighting direction is determined by the lens of the telescope and by the position of the target, so lets The purpose of the invention can also be achieved by the fact that the lens changes when the position changes of the telescope carrier a corresponding

j experiences relative movement.

An example of this type is shown in Fig. 3 at. which the armature shaft 5 of the

'tors 4 is designed as a screw 20 which engages in the worm gear 21. When turning the armature shaft thus becomes the shaft 22

! rotated with gear 23 in the same way. The lens 24 is located in a carriage 25 trained socket, which carries the rack 26, in which the gear 23 engages. One The rotational movement of the armature shaft 5 thus results in a linear displacement of the objective 24 transformed. The button 27 sitting on the armature shaft 5 is used to set the target mark or the lens with the receiver motor switched off 4.

The device described in the embodiments of the invention is first Line used to measure the speed of an io>; moving target to determine the so-called lead angle. The lead angle is understood to mean the angle that the direction of sight is at the moment of the shot must form with the line connecting the gun to the target.

Assume that the wire 19 determining the direction of sight or the lens 24 in ■ its central position and the motor to the gyrocompass device in operation connected. There is now that Submarine in a straight line, so step between that of the gyrocompass device Rose laid down in the room and the parts of the gyrocompass device carrying them no relative movement. The motor 4 connected to the gyrocompass device

Claims (5)

therefore remains at rest, and the wire 19 (or the lens 24) determining the direction of sight thus retains its central position. On the other hand, does the submarine give way to one or the other on the other side of its straight-line travel, that of the Krsiselcompass device retains Rose their position in space, and there is thus a relative movement this rose in relation to the part of the gyro device that carries it. Under the effect of this relative movement, the armature shaft 5 rotates by an angle of rotation the relative movement mentioned at the same angle, the rotation of the armature shaft 5 is transmitted through the mediation of the gears 6, 7, 8, 9, 10, 11, 12 or 20, 21, 22, 23, 26 in the manner on one of the elements determining the direction of sight (wire 19 or lens 24), so that this corresponds to the angle of rotation of the armature shaft 5 Amount, parallel to itself, can be shifted at right angles to the telescope axis. That The gear ratio of the mentioned gear is determined so that the size of the Para] IeI shift of 19 or 24 in each case falls out so that the respective position the same certain direction of sight remains permanently aligned. Should now with the help of the device explained when aiming at a moving target, z. B. , for the purpose of determining the lead angle, the speed moves the target, the periscope becomes when the wire 19 determining the direction of sight moves or the lens 24 is in its central position, on the upright leading edge of the target (e.g. the bow of the ship to be shot at) and at the same time the receiver motor 4 connected to the gyrocompass device. The moving target is then observed until the rear upright edge (e.g. stern of the ship to be shot at) with the wire 19 that determines the direction of sight coincides and the observation time z. B. read on a stopwatch. Since during the. Observation time that determines the direction of sight Wire its location in space under the action of the gyrocompass device connected receiver motor has not changed, then represents the observation period read off represents the time it takes for the target to traverse one of its (assumed to be known) Length took the same route. The quotient of this length and the time you have read gives the speed you are looking for of the goal. Without changing anything in the essence of the invention, the object of the Invention forming telescope equipment z. B. also for gun sights for use reach, which are the direction of sight when moving the Telescope carrier to keep itself parallel. In this case it is necessary to use the telescope movable target mark or the lens to be arranged so displaceably and with a To connect gyroscopic device that the direction of sight determined by the Zielmarkc and lens permanently rectified when the telescope carrier moves in the desired position is held. Instead of a receiver motor, the transmission can also be driven directly by the The main gyro device (mother compass) is carried out to avoid any inaccuracies To exclude transmission to the receiver motor from the outset.
