Francis McCarty at Cliff House


Francis  McCarty  Seems  to  Have  Solved  Problem  of  Atmospheric  Telephone


His  Words  While  He  Stands  at  Cliff  House  Distinctly  Heard  at Cyclers' Rest

    What has been declared an impossibility by men of science, Francis J. McCarty, a San Francisco boy, demonstrated yesterday afternoon to be an accomplished fact. Before a gathering of business men and representatives of the press, young McCarty gave an exhibition of the workings of his wireless telephone to the entire satisfaction of those present. From the transmitting station at the Cliff House the voice of the operator was carried intelligibly and plainly to the receiving end at Cyclers' Rest, a mile and a half away.
    At present the instruments consist of a transmitter and receiver, the transmitter being placed at the Cliff House and the receiver at the Rest. In course of time there will be a transmitter installed at the Cyclers' Rest and return communication between the two places will be complete.
    The receiving end allows two persons at a time to hear the operator. As the flag which signals the Cliff House that the receiving end is ready for business was waved, the men on the receiving end could hear the telegraph instrument at the Cliff House ticking out messages. In fact, before that time there could be heard a faint ticking, which McCarty afterward explained was the Government stations sending wireless messages.
    But the young inventor prides himself on the discovery of the wireless telephone. Soon after the transmitter's telegraph key ceased moving, the voice of McCarty at the Cliff House could be heard saying "Hello, hello," and then he began to talk at different rates of speed, reading extracts and singing. At times he whistled and the instrument recorded the sound. After several minutes of talking the receiving end wig-wagged back that the message had been received satisfactorily and the test was over.
    A visit to the transmitting end showed a home-made board table on which rested the batteries, coil, telegraph key and telephone transmitter. Every article is the product of young McCarty's hands. The transmitter, which resembles that of the ordinary telephone, is specially prepared by the young inventor, as are the coils and receiving instruments. In the work McCarty has had the assistance of A. McAlfrey, who is but a few years his senior.
    The chief difficulty experienced by McCarty and his associate is lack of funds for the procuring, of the proper instruments. While the inventor has incorporated a company bearing his name, he has resolutely refused several tempting offers until he has perfected the machine for commercial use.
    Another difficulty is the lack of proper instruments with which to work. Every instrument connected with the invention is home-made, and one part or another often gets out of order. To obviate this difficulty, McCarty intends to go to New York in two weeks to have instruments made after his plans and within a month will return with the substantial machines.
