LARYNX I 1 by ELMO SCOTT WATSON 1111 is na nn old story about it man who went to a circus and when he be saw a giraffe for the first time in hla his life exclaimed there I 1 aint no such animal A few jear ago if I 1 I 1 you had told tho the average american that I 1 there could be developed a mechanical iman man of steel and iron who could be perform certain tasks and would do them hla his reply would probably be similar to the exclamation of the old fellow who saw his first giraffe and yet the ingenuity of an american inventor has developed such a man but what Is more remarkable still la Is the fact that he be has given his lils automaton a voice and it can now talk back ill I 1 if 11 you are inclined to say there aint no such maul meet 11 mr and his inventor 1 II 11 J wensley ot of the westinghouse electric and manufacturing I 1 company I 1 when mr wensley birti t brought his mechanical roan man into being all that lie he could do was to obey certain commands to accomplish certain specified resu ts ile he could be called upon the telephone and would open and close switches and record the condition of instruments or mechanisms wl with ill which he be was connected but now sir wensley has given him a larynx and the process can be reversed so I 1 that if a report becomes necessary air mechanical arm lifts the receiver of a telephone and ills voice says Is calling main after the telephone connection Is made the eon conversation versa I 1 lon albeit a t prearranged one Is continued until certain information Is conveyed As to how mr Tele vom has found tits his voice it can best be b explained in the words of mr wensley himself who says to give the mechanism means for or er emitting nitting articulate speech of good quality use Is made or of developments in the talking movie tricY astry A piece of moving picture film about 15 25 or 20 feet long la Is spliced to make an endless loop in the present model two sentences are spoken these are photographed near the two edges of 0 the standard film the rest of it being left blank the sound bound appears in the form ot of closely spaced lines of 0 obadee and widths and frequency individual lamps with special straight filament are arranged with lenses to concentrate the ilaha on a very nar I 1 above mr wensley speaks with mr like a perfect gentle man mail the westinghouse automaton responds in i a smooth well wei I 1 articulated voice the ability to talk Is newl for mr Is less than a year old unlike human beings he has an external larynx which Is the large acae box at the right the vocal chord Is composed of voice oscillations recorded on a movie film in the box lower left international news reel photo amr mr further demonstrated his manifold uses when he put a section of the first battalion sixteenth infantry stationed at gov creore island new york city through a portion of the manual of arms recently lower right here is the lar of mr Tel evex 11 the westinghouse mechanical man mr wensley Wen inventor of the automaton seems puzzled as he ha looks over over the thal vocal al chord which Is nothing but a movie film of voice oscillations perhaps he won ders whether the language Is absolute ly fit and proper for reproduction before ladles ladies or maybe he merely Is wondering how ht he can get this huge vocal organ into the windpipe of mr Tile vox unlike human beings mr never suffers from colds row portion of the ahe him film at any one time A small email motor drives the film dim whenever ey er the volet Is required A selecting mecha nisin in the lights either one e of the two lamps depending the sentence desired the image of the filament Is projected through n M narrow slot lot onto the speech record th rousi w which atch it passes to a photocell photo cell A photo c ceil 11 pas passes pases es current directly in proportion tt on to the amount of light falling on I 1 it t As the lines on the film pasa pa sa in front of the light the ilia corresponding change of currents which take place in the photocell photo cell are amplified through a special shielded three stage arnzil tier fier to a volume sufficient to operate a email loud speaker this speaker alcer to la placed in front ot of the telephone transmitter and Is heard by the person at t the other end of the telephone line ex as though a human being wf were speaking the words into the transmitter when a call to Is put through to a sub nub station equipped a having this voice attachment the per person peron on at the remote end will hear a voice saying Te levoi speaking at Randol lh 11 this will repeat a second gln and if the proper signal is not given civen by means ot of whistles or other musical devices the will then hang bang up the th receiver upon the assumption that the call Is a wrong number call in I 1 the meantime the person at the distan end has heard the number of the telephone to which he ha has been connected connected and should it be a wrong number will be able to hang up and signal the op aerator again to bet et the correct number however should the dispatcher I 1 have 1 a e made this call with f the 11 e e expectation alvi fethe t a 0 n 0 f operating operate n g cometh something in g 1 in n the substation station he hd listens for tho ilia voice and as soon as aa he has verified the correctness of the number of the substation as indicated by the telephone number he be blows a blast on the proper whistle and the voice ceases and the tha machine Is taen then in condition tor for further operation by means of the whistle notes should a circuit breaker open automatically mati cally the put into action and lifts the trece f receiver iver of the telephone and immediately Immediate li begins at intervals this Is the calling ing for main alain this will be ba continued at intervals until the central operator Is able to complete the connection to the dispatchers telephone As soon as he hears this voice he will step it by a blast of the proper whistle and then proceed to 0 question the machine by further whistles as aa to what whai nas happened the answers to these will be in the tha buzzer code which the dispatcher understands As soon as the whistle stops the V oace the motor is also stopped and the lamps to so that the flim film Is in use only a very short time white while the usefulness of mr Is at pres present ent restricted to operation in the field of telephony this newest development has great rig eig nit leance for ns as mr wensley says the addition of tills automatic voice considerably broadens the possible field of application for the Te levor it Is not limited to the speaking of the i two 0 sentences s but may be made to answer quite a number of questions correctly when nece alty for such answers has been determined in advance for instance where it Is not desired to use coded code signals indicating the amount of water in the lie reservoir paa this mechanism can be made to state the height of water in feet or it can be made to say that machine Is cool or a machine Is liot hot or a machine is dangerously gerou sly hot it can cad be ma made to repeat any rort eort of routine report that can bo be selected by electrical circuits considering what has already been accomplished in the development of this automaton it would be a rash person indeed who would venture to predict now new what the future limitations in other oilier P fields of usefulness for mr beleus Te leus leret end tits his children will be for more and more we are learning in how foolish Is any declaration of it capt be done when american inventive genius seap about to prove that it can no matter what it may be |
