  • The: coin is retained-sin-positiontITand can as long as it remains-in thisposition be recovered by the hand.
  • the line is energizedin such -aidirection that relay. R2-operates whereas relay-RI is shunted by. the rectifier LI sothatit doesnot receivesufiicint current tobe-able to attract its armature
  • relay Rl-short-icircuitsrelayRlS The speaking device cannow be used and memmng party? can in ordinary mannerdialthe wanted subscriber's number orspeak to an operator.
  • the-stop member S2 is actuated whereby a coin possibly-remaining in .the'coin chute-in vposition II is releasedfand drops into the coin box;
  • the coin is retained on the lower stop member and remains there as long as the conversation During the conversation none of the relasts. lays is energized whereby'a reduction of the microphone current is avoided 'In addition the advantage is obtained that an interruption of the current in the line loop, for instance through the actuation of the switch hook, does not cause any changed connections in the apparatus. Furthermore, the stop memberSI blocks the coin slot so that a coin inserted by mistake does not drop into the coin chute. If the release in the exchange is delayed after the micro-telephone has been replaced, for instance in connection with a trunk connection, a coin inserted by another telephoning party can not be lost but is 7 blocked until the new call has matured.
  • the relay R2 When the new call is made or when a call is received at the coin collectortelephone' station the relay R2 is actuated, and a coin occupying position II is let down into the coin box. An incoming call can be received directly, at an outgoing callthe relay RI is actuated in the above described manner when the called party answers.
  • the coin collector apparatus can be designed for one or'more coins and for coins of diiferent values. If only one coin is to be used the coin contact isclosed by said coin, as is indicated in the shown embodiment. If two coins have to be inserted the coin contact is placed so that it is actuated continuously by the upper coin first when both coins lie on top of one another. When the first coin passes a momentary short-circuiting of the relay RI is obtained but said short-circuit is of no importance since the relay operates immediately thereafter and short-circuits the speaking device anew. If the stipulated charge can be paid either through one coin of a high value or through several coins of lower value two parallel-connected coin contacts are provided which are ac.- tuated in the different coin chutes. If the charge consists of one coin of a certain value and one coin of another value two series-connected coin contacts are provided so that both coins must be 1 inserted to causethe desired short-circuiting of the relay RI.
  • the speaking apparatus and the coin collecting apparatus proper can either be separate, as shown, or built together into a common apparatus in a manner known'per se.
