CHECKS ’PHONE CALLS.

AUTOMATIC APPARATUS. AUSTRALIAN’S INVENTION. An instrument for automatically recording the calls of a telephone has for some months been under test by the officers of the. Victorian postal department, and Mr Itamsay Sharp, since his arrival, has given it his attention. The device is the invention of Mr E. G Godfree, a railway officer in the branch of the engineer for signals, and it has favorably impressed! the officials. The instrument is very small, and no extra current is required to operate it. Its operation! depends upon the co-opera-tion of both parties in communication. By taking the convergers off the respective hooks an effective call is registered, and the instrument cannot be worked again until! both parties replace the conversers, when.' . Loth lamps ; at the exchange switchboard go out, as a signal, that the conversation has been; terminated. It is claimed that effective calls are faithfully recorded in this manner without the aid of operators, who, as the result of being relieved of a considerable : amount of work and worry, earn give more prompt attention to subscribers. An automatic recorder - will be used with the automatic switchboard, which it is proposed to: instal at Geelong, hut so far no instrument is in working which can he applied to the hand-worked common battery ini such a way as to distinguish between effective and non-effective calls. Mr Godfrey’s invention is intended for use in oemmeetion with the common-battery system, and it is claimed that its installation can be effected at very- little cost. ;
