Description

Device for registering the commands or executed machine maneuvers, reported by a command telegraph and an engine room telegraph The invention relates to a device for registering the commands or Machine maneuvers to be carried out by a command and an engine room telegraph and, if applicable, the exact times at which the report was made this command and maneuver takes place. The time-consuming keeping of a telegraph book on the part of the officers on watch, incidentally only a very minor legal one Importance is hereby ruled out.

Devices of the type described are already known, inter alia from Dutch patent specification 36037 and German patents 3h 659 and 312 327. However, these devices have the disadvantage that they are mechanically coupled directly to the bridge telegraph, which limits the possibility of registration.

The invention provides a separate registration device with the one registration in the correct order of all commands of the bridge telegraph and all executed 1 \ Zmachine maneuvers is achieved and at any suitable location, regardless of the location of the bridge telegraph or the engine room telegraph, can be set up. The device according to the invention can, for. B. in the house of cards housed, if necessary in a special waterproof housing that is only accessible to authorized persons. The facility is universal and can be applied to any existing ship's telegraph system without the need for it is to change the telegraph equipment.

The device according to the invention is characterized in that means are provided to make the commands and maneuvers visible that these means be operated at the moment in which a telegraph lever is moved that a Registration in the correct order is then enabled if all actions required for reporting the command or maneuver completed are that the registration takes place at the moment in which the relevant command or executed maneuvers is visible, and that the device after registration is returned to the initial state.

Each registration is preferably carried out by means of a single recording a photographic ga @ mera. This has several advantages. A fraudulent fake a film strip is impossible, besides, it is very easy with a camera in Way possible to carry out a plurality of registrations at the same time. It can be z. B. in the field of view of the camera a date clock with seconds display and a Attach frame counters so that the exact time of each registration is included as well their continuing grief is registered. This makes monitoring very easy, because the order and times of the individual registrations are immediate recognizable - are. You can also add additional secondary registrations; so lets z. B. in the field of view of the camera to arrange a speedometer with the shaft of the Machine is coupled.

Preferably a cine camera is used. This allows Using a 16 mm narrow film 4000 signals and counter signals are registered, before the camera has to be reloaded. For 8 mm cine film, this number becomes doubled for the same film length.

The device according to the invention is preferably designed in such a way that that the means for making commands and maneuvers visible from a command drum exist, on the scope of which the commands and maneuvers are reproduced, so that rotated them one after the other in front of a window that is in the field of view of the camera can be; the drum can be so z. B. by means of an electric motor driven Maltese cross gear so that every single command or Maneuver during a certain time that is longer than the exposure time of the exposure is standing in the window.

The device according to the invention is such that all commands or maneuvers are registered in the correct order. Is z. B. a: maneuver reported by the engine room telegraph immediately after the bridge telegraph has given a command, these actions are always in the correct order registered. In addition, precautions can be taken that a machine maneuver is only registered after it has actually been executed.

The invention is intended to be detailed by describing an exemplary embodiment will be explained, which is shown in the drawing.

In Fig. I an embodiment of the invention is shown schematically; in Fig.2 the Naltesian cross gear designated in Fig. i with 43 is shown; Fig. 3 shows the commands or maneuvers attached to the drum; Fig. 4 represents represents the field of view of the camera in which the window with an arbitrarily selected Command, a date clock with seconds display, a picture counter and a speedometer.

With reference to Fig. I it will first be described from which elements the registration device according to the invention is constructed.

i represents a bridge telegraph and 2 an engine room telegraph. The bridge telegraph i is assigned three contact circles a, b and c, the contact arms of which are coupled to the telegraph lever. A switch-on relay D, a timing relay G and an image relay B are also assigned to the bridge telegraph i.

Similar organs are assigned to the machine room telegraph 2, the are provided with the same reference numerals, but the index for the purpose of differentiation i wear. The three contact circles a1 belong to the engine room telegraph 2, a2 and cl, the switch-on relay Dl, the timing relay G1 and the image relay B1.

The contact circles a, b and c are all attached to the telegraph itself in the case of electrical telegraphs. In the case of mechanical telegraphs, the contact circles can be arranged at any point on the telegraph line, which saves on cable length. The relays and other items are located in the actual registration device, which is housed in a box 3. A command drum 4 is common to the two telegraphs i and 2. This can be set in rotation by an electric motor 5. The transmission between the motor 5 and the command drum 4 is shown in FIG. The number of revolutions of the motor 5 is reduced by a worm gear 6. Between the worm shaft and the command drum 4 there is an intermediate link which consists of a Maltese cross gear 7 and a set of gears 8 and 9.

On the circumference of the drum 4 are in the manner shown in Fig.3 the commands and messages applied, which by means of the bridge telegraph i and of the engine room telegraph 2 can be given (in order to save space the Figure split in half). The left column in Fig. 3 corresponds to the Bridge telegraph i commands, the right column those from the engine room telegraph 2 originating messages. The information in the various columns is against each other offset so that in each position of the command drum only one command or a report behind the window i i is visible, the one in the partition io of the box 3 is provided. The drive of the command drum 4 via the worm gear 6, the Maltese cross gear 7 and the gear 8, 9 is such that with one revolution the worm shaft the command drum is rotated by one field and the this located inscription stands still for a moment before the command drum continues its rotation.

The box 3 is divided into two parts by the wall io. On the the left side of the wall io is the camera 12, which is arranged in such a way that that the window i i is in the field of view of the camera. In this image field is further attached the window of the image counter 13. The field of view can be with two lamps 14 and 15 are illuminated.

The camera 12 can be activated by each of the two image relays B and Bi be set. If an image relay is energized, the magnet armature 16 is in the coil pulled, whereby the lever 17 is moved downwards. This lever operates one Lever 18, which is moved to the right and takes the rod i9 with it, whereby a recording is made. The lever 2o then closes the relay contacts bi and interrupts then the relay contacts b2, making the device in more detail to be explained Manner is decommissioned; with the help of the iga lever, the film in the Camera transported by an image height.

On the right side of the wall io are the remaining parts of the registration device arranged. These parts include the relays D, G or Dl, G1, two contact rollers 21 and 22, which are attached to the shaft of the contact drum 4, and two brushes 23 and 24. A contact roller and brush are provided for each telegraph. The command drum 4, its drive and the regulation regulator V.

The effect of the device according to the invention will now be described. When the lever of the bridge telegraph i is moved from the rest position to another position, the contact arm of the contact circle a passes one or more contacts. These contacts are distributed in such a way that their positions correspond to the graduation marks between the commands on the pointer plate of telegraph i. The contact arm thus always makes contact at the moment when the telegraph lever is between two commands. At this moment, the winding of the switch-on relay D is energized in a circuit which runs over the contact path ä, the contact arm, one of the contacts, the line 25 and the winding of the relay D. The relay D is thus temporarily energized, whereby the contacts dl, d., And d3 are closed. The winding of the relay D then remains excited via the following circuit: -I-, line 26, normally closed contact b2 of the image relay B, line 27, contact dl, winding of the switch-on relay D, -. The switch-on relay D thus remains energized, even if the contact arm of contact circuit a is no longer on a contact. Furthermore, by closing the contact d2, the electric motor 5 of the command drum is supplied with voltage via: -f-, line 26, contact bz, line 27, contact d_ ,, line 28, motor winding, -. The command drum. 4 is then set in rotation. In addition, the lamps 14 and 15 are switched on. The contact d also applies the voltage of the line 27 to the contact track b 'of the contact circuit b. The contacts of this contact circle are arranged so that their positions correspond to the commands on the pointer plate of the telegraph i. If the telegraph lever is thus moved, the contact arm of the contact rose b makes repeated contact, but this contact is interrupted again after a short time as long as the telegraph lever remains in motion. If the telegraph lever remains in a new position, the timing relay G responds in the following circuit: -f-, voltage of line 27, contact d3, contact rose b, line 29, winding of relay G, -. The relay G is temporarily energized repeatedly during the movement of the telegraph lever, but it is with an adjustable z. B. to 3 seconds set Zeitv delay so that it can not respond to the temporary excitement. If, on the other hand, the telegraph lever remains in a certain position for some time, ie if it comes to a standstill, the time relay G will respond after 3 seconds, whereby its contact g1 is closed.

The electric motor 5 has a speed of 1500 rpm. The worm gear 6 causes a reduction in the ratio 1o: 3, so that the wheel 7a one revolution number of 7.5 per second. The Maltese cross 7 has a gear with 32 teeth. That Gear wheel 9 has 144 teeth and is attached to the shaft of the command drum 4. the end the fact that with each revolution of the wheel 7a the Maltese cross one One step further rotates while the wheel 7a makes 1/4 turn, and that the cross then remains stationary for 3 / a revolutions of the wheel 7a, the result is that the command drum is driven in such a way that it stops every i / io second, before it is turned to the next position. The commands provided on the drum stay in the window for 1 / 10th of a second. The recording time of the camera is 1 / 2o of a second.

Two contact rollers 21 and 22 are provided on the shaft of the command drum. The contact roller 21 is assigned to the bridge telegraph i. There are as many contact strips on it as there are commands corresponding to the bridge telegraph i on the command drum. At the moment in which a command originating from the bridge telegraph i on the command drum passes the window ii, the corresponding contact strip of the contact roller 21 comes into contact with the adjustable brush 23. The contact strips are each connected to one of the slip rings 1 to IX, and the $ e slip rings are each connected to one of the contacts of contact circuit c. These connections are such that a contact strip on the contact roller 21 which corresponds to a certain command is then finely connected to the contact of the contact circle c which corresponds to the same command of the bridge telegraph i when this command is in window ii. The connection between the contact circuits and the other circuit elements in box 3 can be made by means of electrical cables. When the timing relay G has responded, contact g1 is closed. As a result, the positive voltage of the line 27 is applied via the contact "1, the contact connection c 'of the contact circuit c and the contact touched by this contact arm to that slip ring which corresponds to the command given by the bridge telegraph i this command is in window ii, the current is closed via the relevant contact strip of contact roller 2i, brush 23, line 30, contact v1, line 31, the excitation winding of image relay B and the - pole, whereby image relay B. and a recording is initiated by the camera 12. Then, as already explained above, the contact b1 is closed, whereby the counter relay N is energized via the line 26, contact b1 and line 32 and is switched one step further the contact b2 interrupted, whereby the line 27 is no longer connected to the + pole, so that the whole system is put out of operation, the Rel ais fall off, the armature 16 of the image relay B returns to its original position and during this movement the camera makes a new recording available by means of the lever 18, the rod 19 and the lever 1911.

At the moment when the timing relay G responds and the contact g1 is closed, the winding hl of the order controller h is also about the following Circuit energized: + on line 27, contact g1, line 33, field winding 1h, -. The order regulator V is brought into such a position that its Armature interrupts the contact v2, creating a circuit in the machine room 2 assigned circuit is interrupted in such a way that a registration by means of this telegraph cannot take place as long as the armature of image relay B does not has returned to its original position.

If the engine room telegraph 2 reports that a maneuver has been carried out, becomes in a similar way as it was described above for the bridge telegraph i, the winding V2 of the order regulator I% is energized, whereby the contact v1 is interrupted will. This has the consequence that the registration of one of the bridge telegraph i originating commands cannot be made until received from the engine room telegraph 2 reported maneuvers is registered. The purpose of this circuit is clear. She prevents that two commands given immediately one after the other are registered in the wrong sequence will. The command given first keeps the registration of the command given afterwards until the first command is registered. Actuation of the armature of the Image relay B can be used to open the camera's spring mechanism; preferably however, the retreat of this anchor is used to produce what is recorded on the film Image to transport an image height, whereby a spring mechanism for the camera is superfluous will.

If the lever of the engine room telegraph 2 is moved from the rest position to another position, the registration takes place in the same way as was described in connection with the bridge telegraph i. In the excitation circuit of the image relay B1 of the engine room telegraph 2, however, a fourth contact circuit m is provided, which is coupled to the engine room telegraph 2. The contacts of this contact circuit m are coupled to the contacts of a contact circuit n. Which is itself coupled again to the maneuvering handwheel 42 of the machine. The circuit is such that when the contact arm of the contact circuit m touches a certain contact, the contact arm of the contact circuit n only closes the circuit if the handwheel 42 is in a position corresponding to the position of the machine room telegraph 2. The circuit of the image relay B1 runs as follows in this case: -i-, line 26, contact b12, line 34, contact g11, line 35, contact rose cl, contact roller 22, brush 24, line 36, contact v2, line 37, contact rose m , Contact rose n, line 37a, excitation winding Bi, -; registration can then take place. As long as the maneuvering handwheel 42 is not in the correct position corresponding to the position of the engine room telegraph 2, that is, as long as the maneuver is not actually carried out by operating the handwheel 42, the excitation circuit of the image relay Bi between the contact circuits m and n is interrupted, so that registration is not possible can be done. During this time the red signal lamp 38 of the handwheel 42 burns in the circuit: + on the line 34, contact d13, line 39, contact s1, line 40, signal lamp 38, -. If, however, the handwheel 42 is brought into the correct position, the connection between the contact circuits m and z11 is closed, whereby the positive voltage comes to the line 37a and the winding of the signal relay S is excited, so that the contact s1 is interrupted and the lamp 38 is deleted. This takes place simultaneously with the excitation of the image relay B1.

The device described above is suitable for single-screw vessels with single or coupled double bridge telegraph.

For twin screw ships with uncoupled starboard and port systems two separate devices can be used, their picture counters with each other are coupled so that the images are numbered consecutively on the two film strips will. But you can also do it with just one facility get along when the total number of commands on the command drum 4 doubles and each the designation SB (starboard) or BB (port) is added to individual commands. The timer and switch-on relays, the contact paths of the contact circuits, etc. will in this case executed twice, but the registration is done on a single one Filmstrip.

A monitoring window is provided in box 3 at 41 which the field of view of the camera is visible from the outside and a reading of the counter relay i1 "is possible. This way you can monitor how many pictures are already on the film strip are registered.

In .der partition io are within the image field of camera 12 also the hand plates of a date clock with seconds display and a tachometer, which is coupled to the shaft of the machine.
