CLASS 20: Railway operations.

The present invention relates to a device on electrically moved monitoring devices for points, which are characterized by the fact that colored signs in the station room indicate the respective position of the Points are marked so that neither special knowledge nor deliberation is necessary in order to be able to assess the position of the switch tongue at once.

The following facility has been set up for this purpose:

The switch tongue stands with two different grinding contacts, which are and waterproof cover are protected from harmful influences, in conjunction.

These sliding contacts are switched on in two equally strong power lines, through which an armature lever d is moved.

The armature lever interacts with the jet disk i , which is rotatable on the axis g and on which the ray-shaped part of the characters K 'K "K"' is located (FIGS. 1 and 2).

The arm lever d and with it the part of the symbol is moved to the right or left by the two magnets a ¹ a ^{11 by} means of a current connection, while they are held in the middle position by springs ee when the electromagnets are de-energized.

The symbol part swings behind one cut out according to the symbols I, II, III or a colorless glass plate in these places.

In addition, a colored, roughly red background is attached behind the drawing part, which becomes visible when the character part is in the middle position.

On the part of the character, the middle character K " is colored black, while the two sides K ' and K'" are green.

The effect of the device is now as follows:

If the switch is set to "open", the currently standing green sign (position I, Fig. 3) visible behind the upper cutout of the glass plate, while the inclined cutout the glass plate is covered by the black center mark, because the switch tongue is the one Contact is closed, which rotates the anchor lever with the symbol part in one direction.

If the switch is closed, ie on "deflection", the inclined green sign that is significant for the deflection (position II, Fig. 3) appears. In this case the switch tongue has closed the contact, the current of which influences the armature lever d in such a way that the mark-carrier disk is rotated in the other direction; the black mark has covered next to it, as can be seen in position II, FIG. 3.

If there is no current at all in the electromagnet, the springs ee come into effect, and the part of the symbol comes into the middle position, in which neither the black middle symbol nor the green symbol appear behind one of the cutouts.

In this case there is no sign at all behind the cut-outs, but rather

Claims (1)

only the red or somehow colored background is visible (position III, Fig. 3), as Characteristic for the fact that the switch is neither "open" nor "closed", but in disorder is. It is thus with the help of the contact closures, which by various Switch positions are brought about, caused twisting of the character carrier disk always indicated by permanently visible colored signs whether the switch is "open" or is "closed"; if the tongue is imperfectly standing, on the other hand, it becomes clear Warning signs visible, caused by a spring-induced mid-position of the Anchor lever with the character carrier disc. , The device described starts working attach to each turnout, and the drawing box needs little space to accommodate in the Ward room. Patenτ claim: In the case of electrically operated monitoring devices for switch positions, a display device characterized in that, depending on the position of the switch, a ^1- colored disc appears in front of one of two different positions on the panel, while the other opening is covered by a black disc the purpose, from the position of the colored field, the position of the switch and from the absence of each colored field, respectively. the appearance of the different colored background immediately recognizes the imperfect switch slack. 1 sheet of drawings.
