Title: Improvements in or relating to telephone devices
Inventor: GILES MAISIE ELIZABETH
IPC: H04M15/30
Filed: 1962-12-06
Abstract: 1,041,050. Telephone time-alarms. GILES (ELECTRICAL ENGINEERS) Ltd. Dec. 6, 1963 [Dec. 6, 1962], No. 406068/62. Heading G3T. [Also in Division H3] The lifting of a telephone handset starts a timing device in the cradle whereby a warning signal is given to the user, and is repeated at desired intervals until the handset is replaced. The device is illustrated in Figs. 1 to 5 (not shown). The cradle is formed by a casing 1 having a spring-biased lid 6 which rises to close a micro-switch 2 in a timing circuit, Fig. 2. Two relays H/2 and B/1 are energized and two capicators C10, C11 charged. Relay A/2 opens two normally closed switches A1, A2 thus isolating C10 and B/1 from the supply. Relay B/1 closes a switch B/1 in an alarm circuit such as Fig. 5 so that the buzzer and lamp shown are operated. This initial operation is not important as the user will still be dialling. Relay B/1 holds on for about a second until C11 has discharged. Then the alarm circuit is broken. Meanwhile C10 in the base circuit of a transistor OC72 discharges and determines the actual time interval. When the transistor cuts off relay A/2 falls off, reclosing contacts A1, A2 and the cycle is repeated until the handset is replaced. The interval may be varied by resistor R16. The circuit of Fig. 5 may be replaced by a signal generator of induction type, Fig. 3. This includes, from left to right, a transistor multi-vibrator circuit having two amplifying stages and a power output stage feeding into an air spaced coil connected to the output stage collector and which is arranged round the interior of the casing 1 so that its energization produces an audible noise in the earpiece. The supply is connectible via the contact of the second relay which lights a lamp at the right. In an alternative signal generator, Fig. 4, a transistor multi-vibrator energizes, through an output stage, a loudspeaker in the casing and a lamp to show that the device is in operation. The timing circuit may be replaced by a clockwork mechanism.
