Abstract: 223,981. Jackson, W. J. Mellersh-, (International Callophone Corporation). July- 31, 1923. Direct-call systems in which each of a number of stations can call or be called by a central station are provided with means whereby the station making the call completes the talking connections without any operation by the called party. In addition, the central station can talk to several outstations at once. Call by central station. The wanted station is selected by means of switches A<1> - - A<3> controlling respectively relays R<1> - - R<3> and in common relay R<c>. When the switch. A<1> is turned counter-clockwise both its springs are operated. Relays R<1>, R<c> pull up in series over 31, R<c>, R<1>, A<1>, 32 and interrupter 13 at the central station is energized by relay R<c> in series with the primary of transformer T<c> the secondary of which is connected to the loud-speaker 12 of the wanted section by the relay R<1>. At the same time the out-station microphone 11 is connected in series with battery 30 and primary winding of transformers T<d> the secondary of which is permanently connected to the central station loudspeaker 12. When the wanted station replies, key A' is turned clockwise and springs 8, 9 separate. Relays R<c>, R<1> hold up over springs 6, 7, but the buzzer is disconnected and the central station microphone across which it was shunted becomes operative in its place in a circuit 31, 35, 60, 11, 65, T<@>, 32. A call to a group of stations is made by operating the key A<4> to energize relay R<4>. This relay has a spring 38 and as many springs 39 as there are stations in the group so that the central station can call and talk to all these at once, and also a spring 37 and a number of springs 36 (not shown) to enable the stations to reply. Relay R<c> operates to energize the central station buzzer and microphone. Call from an out-station.. The springs 6, 7, of the out-station key A<10> are in parallel with those of the corresponding key at the central station, so that when the key is operated, relays R<c>, R<1>, pull up and complete the talking circuits both ways as in the case of a central station call. In the calling position however, the out-station microphone is shunted by the out-station buzzer 11 which operates and affects the central station loud-speaker.
