PATENT OFFICE.

The present invention relates to a call counter for telephone stations, which the calls by number or time or by number and time for the calling party records.

In this case, the lever that triggers the counter can only then be set in motion if the calling participant shortly before the signal for the beginning or end of the Conversation has given. ■

One embodiment of this idea is through US Pat. No. 5581.68 known.

According to the present invention, which is a simplification compared to that older arrangement the construction aims, a lever is released from its inhibition after giving the call signal and can then be moved by the handset hook to cause the counter to advance.

In Fig. Ι shows α the switch-off lever of the handset. A lever d is connected to the same by the springs b and c , through whose movements a pointer mechanism e respectively recording the number of calls. a . the talk time measuring clockwork, indicated by the anchor f, advanced respectively. is triggered.

If the locking device g were not present, the lever d would be moved with every movement of the receiver hook α and each use of the receiver would be noted. "The inhibition g locks the lever d , but without hindering the movements of the receiver hook α because of the peculiar connection by the springs b and c.

If the signal for the beginning or the end of a call is given by means of the telephone set to which the call counter belongs, then the inhibition g is brought into position g ^l by pressing the signal button or by moving the inductor, whereby the lever d is released .

Since the escapement g is attached to the pull-up axis of a drive hi k I, in which the pull-up axis moves back into its original position when it runs down, the drive is pulled open by the movement of the escapement to g ¹ and runs slowly, which only after some time the escapement returns to position g and locks lever d.

This results in the following effects of the conversation counter:

If the interlocutor has been called, the conversation will not be with him recorded; are the positions of the most essential parts

while being called as in Fig. i, jamming device position g,

when speaking as in Fig. 2,

during the final signal as in Fig. 1, jamming device position g \

a short time afterwards as in FIG. 1, inhibiting device position g.

If the participant called himself, the conversation will be recorded with him; are the positions of the most essential parts of the conversation counter

when calling as in Fig. 1 with position g \

when you pick up the receiver as in Fig. 3 with position g ¹ ,

Claims (3)

when speaking as in Fig. 3 with position g, after the end of the conversation, before the final signal as in Fig. 4, during the final signal as in Fig. 1 with position g ¹ , a short time afterwards as in Fig. 1 with position g. ■ '-, The call time or the number and time of calls is to be recorded by the call counter it is in the own interest of the conversation partner who initiated the conversation that he should also be gives the final signal, otherwise the clockwork would continue to run. If only the number of calls is to be recorded, if that occurs End signal is not given, the effect of the same on the next call. , If a participant has several conference units that. both immediately with each other and are in contact with the mediation office, it may appear desirable that only those conversations which are mediated by the office are recorded will. ■ This purpose is served by an embodiment illustrated by FIG. 5, in which the lever d is still blocked by a second inhibition m , which only releases the same again when the inhibition m has been brought into the position m ^{1 by a corresponding arrangement of the plug contacts, etc.} is what z. B. can easily be achieved by the fact that the plug-in contact establishing the connection with the office pushes the inhibition m to m ¹ when it is pushed into its opening. The inhibition g could also be brought into connection with electromagnets to be excited by the current of the signaling apparatus instead of a drive hi kl, so that when the lever d is called, the lever d is released, but when it is called, it is inhibited. Patent claims: ι. Call counter only when the caller talks one, characterized in that, that a effected with the remote handset hook (a) resiliently connected lever (d), the die'Fortschaltung of the counter, the movements' of the hook (a), only then can follow if by giving the call signal from the hem. mung (g) is exempt. 2. Embodiment according to claim 1, characterized in that the escapement (g) is gradually restored by a spring mechanism . is returned to its original position. 3. Embodiment of the telephone meter according to claim 1 for those telephone stations that can be connected both directly to each other as well as through mediation of the office with other telephones, in which, however, only the calls made through the office are to be counted, characterized in that for the lever (d), in addition to the inhibition (g) , a second inhibition (m) is provided, from which it is released by the caller when the connection with the switching office is established. 1 sheet of drawings.
