Abstract
311,450. Richardson, S. Feb. 11, 1928. Systems for transmitting music &c.-Apparatus for the reception and distribution of wireless signals comprises several wireless receivers connected to low-frequency distribution lines, and a number of listening stations provided with selector switches. As shown in Fig. 1, a central station 1 is provided with two or more receiving sets 2 - - 4 and aerials 5 - - 7 tuned to different transmissions. The sets are connected through amplifiers 8 - - 10 to low-frequency re-transmitting devices 11 - - 13, which distribute the received signals through land lines 18 to any desired number of listening stations 14 - - 17. Each listening station has a selecting-switch 20 to connect its receiver 21 to any desired landline 18. An earth return may be provided. The receiver 21 may be of a visual or audible-type, or may be a recorder of Morse signals. Substations may be interposed between the central station 1 and the listening stations 14 - - 17, and these sub-stations may be telephone exchanges with separate wires provided for the wireless programmes. Selecting switches may be provided at the central station 1 for delivering the programmes to predetermined recipients.
