| ASBURY PARK, N. J., has the unique distinction of being the first city in which boardwalk roller chairs have been equipped with wireless telephone and telegraph receiving apparatus so that the passengers are enabled to hear talking and musical concerts from distant stations while the chair rolls merrily along.
W. Harold Warren, who some time ago demonstrated that it is possible to receive wireless telephone and telegraph signals within a steel and concrete bank vault with both inner and outer doors closed and with no external connections to the instruments, is responsible for this new innovation that has already proven so popular at this charming seaside resort. A small flat "loop" replaces the ordinary aerial and ground connections, and the whole apparatus is so compact that three persons can sit with it comfortably in the chair. The most interesting part of the installation is the fact that the vibrations of the roller chair in motion have no effect whatever on the reception of the signals. The directional effect of the "loop" is most pronounced, the strongest signals being received when the vertical plane of the "loop" is in the direction of the transmitting station. Signals from stations over 200 miles distant are received with the apparatus. |
