Equipment for signal devices with several signal positions.

Patented in the German Empire on November 7, 1912.

The invention relates to a device for signaling apparatus with several signal positions. In such devices, the arrangement is often made in such a way that by short successive power closures a disc is brought into different positions and a different one in each position Signal is indicated by the disc. If with these devices a given

ίο signal is repeated again to the operating personnel to give a reminder at the receiver if the given signal is not executed takes place . the first another false signal. It

would, for example, when the signal corresponding to a single power supply is switched on is through a subsequent power cut in a certain time interval - instead of the existing one the signal appear which corresponds to two power closures in quick succession. You could now after submission of a signal block this immediately, then it would not be possible, however, by successive Power closures to give various signals through an apparatus'. It facilities are now known in which a given signal takes some time is blocked by special 'time drives are arranged, which when a signal is given are driven by electromagnets, run slowly and then a lock switch on for the given signal.

The subject matter of the invention differs from these devices advantageously in that that a designed as a pendulum delay device is provided, which upon delivery of a signal is set in oscillation and is only blocked in the rest position caused by the respective signal position, so that the swinging of the pendulum back and forth a Delays the blocking brings about. The blocking is lifted automatically at Resetting the signal to the rest position. This facility has opposite the known arrangement has the advantage of cheapness and absolutely safe mode of operation, since Electromagnets, special timing mechanisms and the like are avoided.

The structural design of the inventive concept is shown in the drawing, for example in Fig. 1 in front view and in Fig. ζ in side view schematically shown.

In the front view, for the sake of simplicity, only the pendulum ft is shown, namely in the rest position f and the two outermost positions g, e, which it assumes when swinging. In the side view, the work coil of a signaling device is labeled »». Each time the current is closed, the armature α is attracted by the magnet m and the gear wheel r rotates by one tooth. Each rotation results in the appearance of a new signal in that, for example, one or more signal disks (not shown in the drawing) are coupled to the gear wheel r. At the same time, the spokes s, s ¹ , s ^{2 are} rotated in stages so that when the first signal appears, the spoke s assumes the position shown in the drawing, when the second signal appears, the spoke s ¹ , etc. When the anchor is tightened, α is also the

Claims (1)

Pendulum ft is set in oscillation by, for example, a locking hook k, which holds the pendulum in one of its extreme positions, being knocked down by the spoke s. The hook k is only returned to the locking position recognizable from the front view when the signal is returned to its rest position. The device which brings about this return is not shown in the drawing as being irrelevant to the invention. As a result of this arrangement, the pendulum can only be set into oscillation when the armature a is attracted for the first time, while further current circuits, which result in the armature α being attracted, have no effect on the pendulum. The pendulum ^ is provided with a locking piece t . In the normal position, the pendulum ft is in a position in which the locking piece ii cannot inhibit the movement of the spokes s, s ¹ , s ² etc., for example in the position at g or e. Even during the period of oscillation of the pendulum ft, the locking piece t does not prevent the movement of the gear wheel r or the spokes and signal disks. One could assume, however, that the swinging pendulum ft inhibits the movement of one of the spokes s sliding down through the locking piece t when the pendulum ft comes into the central position at the moment at which one of the spokes s is being moved. However, this is not the case. As tests have shown, the case virtually never occurs at first, in which the locking piece t hits a spoke s that is in motion when the pendulum ft is swinging. If this should happen anyway, the weight of a spoke s and the accessories is too low and the oscillating force of the pendulum ft is so great that it is not stopped in its movement by a spoke s falling on the locking piece t. As a result, the spoke s slides down from the locking piece t , the surface of which is suitably curved. If, on the other hand, the pendulum ft comes to rest, the locking piece t ^{lies under the spoke s, s 1} , s ² , which are respectively brought into the corresponding position, so that the tightening of the armature a remains ineffective. If, accordingly, a certain signal is given by a single current connection and this is repeated after a time after the pendulum has come to rest, the second current connection remains ineffective, as just explained. If, on the other hand, the current closings take place during the time in which the pendulum has not yet come to rest, the spokes s do not find any resting points on the locking piece t sliding back and forth, and the spokes s, s ¹ , s ² get into the unhindered Position, 'which corresponds to the number of power closures. Sponsorship τ claim: Device for signal devices with several signal positions to block the Signal position after a certain time, characterized in that the locking device is designed as a pendulum, which is set in oscillation when a signal is emitted and only in its Rest position causes the respective signal position to be blocked, so that the and swinging the pendulum delay the locking. 1 sheet of drawings.
