And with a powerful organization behind them it was not necessary for Carty and his associates to starve and skimp through interminable years, handicapped by the inadequate equipment, while they slowly achieved results. This great organization, working with modern methods, produced the most wonderful results with startling rapidity.
Carty once said that on account of his distinguished scientific attainments and wonderful telephonic inventions, Professor Pupin would rank in history alongside of Bell himself.
His father was a gun-maker and an expert mechanic of marked intelligence and ingenuity who numbered among his friends Howe, the creator of the sewing-machine. As a boy John Carty displayed the liveliest interest in things electrical. When the time came for him to go to school, physics was his favorite study. He showed himself to be possessed of a keen mind and an infinite capacity for work.
These were a constant source of difficulty, and Carty directed his own attention, and that of his associate engineers, to finding a satisfactory solution. He sought a method of utilizing one common battery at the central station and the way was found and the improvement accomplished.
But the delicate microphone would not carry these stronger currents. Increased sensitiveness in the receiving apparatus was also necessary. Not content with their accomplishments in increasing the scope of the wire telephone, the engineers of the Bell organization, headed by John J. Carty, turned their attention to the wireless transmission of speech.
The two walked down Broadway toward the elevated road, Rex's dark eyes gathering amusement here and there in the crowded way as they went. "Look at Billy Strong why there's Billy Strong across the street. Come over and I'll present you, Carty. Just the chap you want to meet. He's a great athlete on the water-polo team of the New York Athletic Club, you know as much of an old sport as you are."
By 1901 Carty was ready with another invention which was to place the telephone in the homes of hundreds of thousands who, without it, could scarcely have afforded this modern necessity. This was the "bridging bell" which made possible the party line. By its use four telephones could be placed on a single line, each with its own signal, so that any one could be rung without ringing the others.
Thus Vice-President J. J. Carty, of the American Telephone and Telegraph Company, who directs its great Department of Development and Research, and Doctor W. J. Whitney, Director of the Research Laboratory of the General Electric Company, have repeatedly expressed their indebtedness to the investigations of the physicist, made with no thought of immediate practical return.
A double track of wires is made to carry three talk-trains running abreast, a feat made possible by the whimsical disposition of electricity, and which is utterly inconceivable in railroading. This invention, which is the nearest approach as yet to multiple telephony, was conceived by Jacobs in England and Carty in the United States.
Oh, do tell me that he has a yachting cap!" Miss Van Arsdale, smiling, shook her head, but her eyes were troubled. There was compunction in Io's next remark. "I'm really going over to see about accommodations. Sooner or later I must face the music meaning Carty. I'm fit enough now, thanks to you." "Wouldn't an Eastern trip be safer?" suggested her hostess. "An Eastern trip would be easier.
