To whom, concern:
Be known that Nikola Tesla, from
Smiijan, Lika, border conntryof Austria-Hun
gary,and residing the city, county, and State
of New York, have invented certain new and
useful Improvements the Transmission of
Power, ofwhich the followingis specification,

the other hand, necessary, attain a
greater economy conversion than has here
tofore existed, construct cheaper and more
reliable and simple apparatus, and such that
all danger from the use currents high
, tension,which are necessary economical
transmission, may avoided. TESLA, NEW YORK, Y. 252,132.
