PORT PERRY, a o BLU ERE 'PLUMBING TINSMITHING ONTARIO If the inventor of the telephone, Alexander Graham Bell, were alive today he would not:be too greatly sur- prised at"the new devices which fea- ture modern telephone dervice. From the moment when his dream of talk- ing over wires became a reality with the first erude instrument, he visual- ized its application on. a universal scale, Bell was born'in Edinburgh, Scot- died, in August 1922, he had 'seen an immense, communications system blossem from the tiny seed he plant- ed only forty-six years before, Bell's father, Professor Alexander Melville Bell, had been a teacher of elocution and was the inventor of phonetic alphabet which he called "Visible Speech", This consisted of a series of symbols indicating the pos- itions the speaking organs take in uttering different sounds, It was most useful in teaching the deaf to speak. - ALEXANDER GRAHAM, Graham Bell followed in his fath- er's footsteps. For reasons of health he came to Canada in 1870 to join his family which had settled near: Brant. ford, Ontario, a short time before, He regained his health and in 1871 took up his father's work instructing tea- chers of deaf children in the use of Visible Speech at Boston and other American cities, It was a lucky combination of a spare-time interest and his daily work with the deaf that started Bell thinking on the lines that led to the telephone idea. He was interested in telegraphy, and, with his Knowledge of sound and speech, begun to con- template the possibility of speech be- ing transmitted over a wire by elect- ricity. TELLS FATHER During a summer holiday at Brant- ford, Ontario, in 1874, Bell outlined to his father his now historic concep- tion: "If I could make a current of electricity vary in intensity precisely as the air varies in density during the production of a sound, I should be able to transmit speech telegraphic LXTTTY DEALER CARRIE.

HARDWARE ELECTRICAL APPLIANCES Telephone "Invented by Alexander fell ally," Haunted by the idea, Bell worked at it unremittingly and devised in 1875 his first 'crude telephone, "The mit only meaningless sounds, Endless hours of work and thought followed until in March, 1876, the first intell- igible sentence was transmitted over wire. Bell was experimenting with a diaphragm held over a tiny cup of dilute acid. Suspended from the dia- phragm and dipping into the acid was a thin wire; Current flowed from a battery into. the suspended wire, through the acid, into a second wire and along it to the receiver in another room. As a sound caused the diaph- ragm to vibrate, the first wire was lowered into the acid to a depth de- pendent on the strengh of the vibra- tion. The depth of immersion of the wire determined the amount of curr- ent which would flow through the acid, Consequently, the electric cur- rent flowing through the circuit var- jed in intensity with the vibrations of the diaphragm. At the receiver end of the circuit were a magnet and an- other diaphragm so arranged that the varying current caused the mag- net to exert a varying pull on the diaphragm and reproduce the original vibrations, It was while experimenting with 10, 1876, that Bell spilled some of the acid on his trousers and exclaimed: "Mr. Watson, come here! I want you!" Watson. at the receiver in an- other room, heard the words distinct- ly COMING FROM THE RECEIVER and rushed in to tell the young invent- or of his success. Bell gave his first public demon- stration of his successful telephone at the Centennial Exposition in Phil- adelphia on June 25th, 1876. Only two distinguished visitors, the Emperor of Brazil and Sir William Thompson, later Lord Kelvin, were openly enth- usiastic. Despite the skepticism of the majority, the interest of these two men, one a monarch and the other the world's most eminent electrical scientist, focused attention on the inventor. . On August -10th of that year, Bell conducted the first successful one- way long 'distance telephone test in the world, from Brantford to Paris, Ontario. The distance between the two places was 'only eight miles but the voice currents had to he trans- mitted - form Brantford to Paris via Toronto, where the "battery supply was located; thus the circuit actually totalled about 186 miles.

Yr Precautions Taken To Ensure Efficient Telephone Service -. Behind the 'scenes at the central office busy generators hum to keep batteries charged with the electric current that carries telephone mes- sages. Ordinary electric power is not suitable for this purpose because it is an alternating current, and the talking channels. of the telephone sy- stem require direct current. So the telephone company uses the commer- cial electricity supply to run its gen- erators which produce direct current, Huge batteries are kept contantly charged so that, in the event of fail- ure of power supplied from an out- .

As additional in- | surance, 'standby generators, usually & driven by gasoline or diesel engines, are provided in all large central of- fices. In Bell territory, more than one instance is recorded of central office generators being employed to aid in the restoration of other essen- tial services in communities stricken by storm or flood, Telephone signals must be audible and distinctive and there are machines in the central office which produce the special current needed to ring telephone bells, supply the "busy" signal and other audible indicators.

On the average, every 550 feet of underground conduit is broken by a man-hole to allow sections of cable] to be spliced together. The man- holes vary in size; some are only large enough to accommodate one or two telephone workers, others are 12 feet square, 12 feet high and have a mezzanine floor! Such larger types are neetled to hold the loading coils which improve transmission on. the longer telephone lines. Even the compact unity of the cable crrying many lines does not entirely |§ solve the question of a cumbersome plant. Suppose there are 10,000 tele- phones in an exchange area. . If each telephone had to have a direct line to every other, there would be 49,995,000 pairs of wires running through the city streets, in cable on poles, or in underground conduit. Fortunately, this mathematical puz- zle is solved by switching equipment in the exchange, which enables the dial mechanism or an operator to ake any one of the 49,995,000 con- nections. Ag the wires. come into the. central office from the street; they are fan- ned out from the cables to racks call- ed "frames". On the first frame, the wires are connected to fuses and pro- tectors to guard exchange equipment against any dangerous "foreign" cur- rent that might come in over the From the other side of the frame, other wires lead to a. second frame. On the second tain, lines are 'so arranged that one group of dial swit- ches, or any one operator does not have to answer more calls than an- other. By making cross-connections on the frames, it is possible to bring each telephone user's line to its pro- per 'terminal in the switching equip- ment. .
