Abstract: 1,015,853. Coin-freed television apparatus. BRITISH TELEMETER HOME-VIEWING Ltd. Oct. 9, 1962 [Oct. 10, 1961], No. 38148/62. Heading G4V. [Also in Division H4] Subscribers to a multichannel television distribution and subscription system select a wanted channel by depositing coin value appropriate to that channel. Each receiver has a PAYSEE switch which in the PAY position allows the insertion of coins in a slot 20. Depending on the value of the coin or coins, pulses are generated at a contact 30 to step a ratchet wheel 36. When the switch is moved to its SEE position a contact 24A connects signals from the network 14 to receiver 12, the signals passed being those that are not shunted by one of the channel filters 46A to 46E. In the SEE position the switch obstructs the coin slot 20. To change channel the subscriber must turn the switch to PAY position and in doing so operates contacts 24B which removes the ratchet and restores the ratchet wheel to its normal position in which no channel is connected as all filters are earthed. If otherwise unrestored, the ratchet wheel is restored in the small hours after transmission has ended by a clock 45 which breaks contacts 44, or these contacts can be broken by a signal from the transmitter at the end of transmission. When the switch is in the SEE position a cam 60, Fig. 3, presses a pen 54, the angular position of which depends on the channel selected, on to a record disc 56 which is driven by clock 45 to rotate one revolution in 120 days. The channel selected by a given coin value is set up on an illuminated indicator.
