Show new inventions in telegraphy boim poun MESSAGES SENT simultaneously OVER ONE ose WIRE MIRE IN OPPOSITE t DIRECTION directions S wednesday afternoon after norm nonn last at the bro tro broadway adway office of the tile western union telegraph company a test was made of an invention which promises to be almost more important to the present ago than were morses morsels first achievements to the people of his an own time the test resulted successfully sully and it proved that four mes sages abian ican lean bo be simultaneously sent rent ana single wire in 0 opposite p osita dictions and arld with no more liability ta nii iiii stake tk etli thau than au as ius if an equal wires 1 r e s were used to M make ake the clear elear it IC will wili be necessary i to look a little backward back warL 1 morse dior se took the first step in telegraphy and the first is always the greatest by the invention of a system by which messages col coi could ild lid be de sent between any two terminal llon llen points arnd annd dropped at any way station oh the tile circuit the objection to this system was that the transmission ot oi a single message occupied a wire entirely and though electricians were convinced tha that t a different result could bo be attained attal attai no one showed howit how it could be done until so BO recently as three years a ago agn mr J B St steams caruss ini yi 3 40 vented the duplex that was the second great step fifield an d it instantly doubled the capacity of every wire which ever had been erected by the tilo stearns steams process two messages can be sent simultaneously on a single wire in opposite directions between anyiwo terminal points but this system liko like the morse had its objection the message could riot not bei be dropped at anyway any way station except by the tho use of a repeater nevertheless the invention was recognized as of immense practical importance throughout the world Two days agoras ago was taken a third great astep tep and one not inferior to either of af the others it needs only to be said of it to recommend it to tho the least in one instance it wl 11 quadruple the usefulness of the miles of wire owned by the western union telegraph compain compain y it is a new process of multiple slon sion by which two messages can be sent simultaneously in the saine same direction over the tiie samo bamo wire and either message can be dropped at any way station on the circuit nor is this all ali the old duplex system can boa bo bon applied plied piled to the new invention any ady 3 and by the combination four messages can ead be sent simultaneously over the same wire in opposite directions between any two terminal points and not the least recommendation of the discovery is ls that it calls for no changes the old oid morse key is used without the need of any new class elass of operators tas fas as in the automatic telegraph and wi with th no duplication ex except ce pt as to parts of machinery the invention is the result 0 of f ti the tho joint labors of george H prescott and thomas A edison and if not scientifically at least practically a great deal of credit is also due dile to the enterprising policy of mr win wm orton the president of the company of c ourse course it is 4 needless to udd udd add that the new system will be speedily put into practice by the western union company by whom the patent is controlled it will make itself felt in more ways th than anone one Forina eor for instance tance the western union telegraph company have been forced to erect goow goom miles of wire during the last three thred years and of course at an enormous enormous expense an indefinite future like that thai could not be very satisfactory to stockholders nut but this year scarcely 2000 need be erected and every wire is practically four but without further enlargement rin and d almost inthe in the words of mr orton tho discovery may be called the solution bof pf all the tho difficulties in tho the future of telegraphic sc ienco science ar y ayn timea times W |
