W W. W Macfarlane of Philadelphia as described by the Electrical Experimenter Mrs Macfarlane l sitting in the garage back backof backof backof of the Macfarlane home was talking through tho the wireless telephone to her husband seated comfortably comfortably comfortably com com- in a moving automobile GOO yards awa away The occupants of the car were a chauffeur a the telephone telephone telephone tele tele- reporter and a photographer All wore phone receivers and could hear everything Mrs Macfarlane was saying The chauffeur had no other apparatus than the receiver with the usual telephone cord attached by a metal clip to his steering wheel Lying beside Mr Macfarlane was tic the foot foot- oot square box the only secret in the whole demon demon- What is in the box is the inventor a mystery This box weighs about twelve h Is The other machinery used consisted only of th the usual telephone transmitter and receivers and the How TEI TELEPHONE EPHONE CONVERSATIONS Mav May Be MELD HELD f t three ree pieces of stove stovepipe pipe standing erect erection on a plain piece of board This forms the aerial of the apparatus Before starting on the automobile demonstration tion of his wireless telephone Mr rr Macfarlane stood in the garage garag-e and directed the movements of oC oCa a soldier in a field more than yards away from him This sold soldier er assistant had a pair of telephone receivers over his head connected by bya a wire with two metal clasps to his rifle He Ho marched and halted and faced about-faced and left left- shouldered-arms shouldered out there in the field the instant Mr Macfarlane gave the or order er through his little hand wireless phone in the garage Mr Macfarlane said he would make no fanciful fanciful fanciful fanci fanci- ful predictions as to td what his simple portable wireless telephone might do There are all kinds of possibilities in it the Electrical Experimenter quotes him as saying If this could have been ready for use in the war think of the value it would have had A whole regiment equipped with the telephone receivers with only their rifles as aerials could advance a While Whale TRAVELING in in AUTOMOBILES mile and each would be instantly in touch with the tho commanding of officer No runners would be needed There could be no such thing as a lost battalion No high power is necessary to operate this wireless I am using om tenth one tenth of an ampere in inthis inthis inthis this experiment here and the results you see are areso areso are areso so good that the voice carries as well as on the usual wire telephone The telephone system uses uses about one-fourth one of an ampere I am nm working on a new theory in electricity and md in wireless I think the accepted principle of the waves is only part of the story There is something something- else It is that something else that I Iam Iam Iam am utilizing There is no 10 o supplementary current in this system as fiS in the usual wireless operation There is no static and no interruption An umbrella Mr 11 Macfarlane explains will serve as well as a rifle for an aerial A plain citizen carrying a small handbag containing the compact wireless outfit and with his umbrella held aloft can walk along the street talking with f fr friend r lend cn wife at the house at the i other end of th the city he said How costly would this outfit be ben he was asked Nothing new is used he explained AUthe All AU the apparatus fits in with existing devices Everything Everything Everything Every- Every thing needed for the outfit could be bought for probably 15 My apparatus here is rather crude erode and not all the quality of current is obtained that I can get he continued But it is no wild dream to to say that a man riding on a train to N New ew York can telephone his wife about bringing a a. friend home for dinner by using this device It will be bo 1 perfected thus far before very long This ap apparatus apparatus apparatus ap- ap here needs improvement but it demonstrates demonstrates demon demon- strates the practicability of the thing Even now I can connect up the end of the wireless in the house with the existing telephone system and thus can talk from my automobile with any person person per per- son in the city j a |
