Patent Which "Wu Save Millions" Gift Army People

on the various details Of the invention !
will, however, quote.
In the first place he desires me 20 make II
clear that he has invented no apparatus
has only combined the wire telephone an'
paratus and wireless telegraph apparatus
already on the market and Joined these 70
wonderful high frequency generator.
also the product OF another inventor.
The rotor Of this generator revolves o.
mn times per minute" he explained. "and is
one foot I'm diameter Its speed Ia so great
that. II used as a wheel, it would roll as
far az from New York to San Francisco in
four hours and thirty-ono minutes.
The electric vibrations which this ma
chine sends out along the wires will travel
as fast a. light. They will pass around the
earth seven times i'm q single second. II
the generator were connected by wire 10
the sun any one OF these vibrations OF
waves would pass from Major Squer's lab
oratory 10 that orb or day in eight minueS.
Now, i'm ordinary telephony much slower
electric vibrations must be used The new
generator which the major has installed
Is the only type which has ever supplied Vi
brations Of such high frequency 10 tele-
phone or telegraph wires. Through our
phones Of commerce the electric vibrations
which carry our conversation have ire
| quency Of only 800 TO 10 per second. They
are all audible TO the human ear, when
can hear vibrations coming not slower
| than about l5 per second and not faster
than from 1900 to 2o09o per second. But
the vibrations employed i'm Major SPul"r
| invention are much faster than tho most
| acute ear can perceive, although Tn" mes
| sages which they carry are made audible
| by complicated details Of the apparatus.
| They rush through space at speed vary
ing from 2000n To 10000 per second. The
vibrations used in wireless telegraphy are
| still faster. 80 fast that they rsdate IN all
directions. regardless of wires.
So tho u"v invention employs an inter
mediate class Of vibrations. which arc
faster than the fastest audible vibrations
| vet slower than the eIowest wireless feie'
graph vibrations Never before have Nihra
tions OF such speed been successfuliv ap-
Piled 10 wire lines.
They are so fast indeed. that they Jump
| from the WIRE instead Of travelling through
| Il, like those used ir all telephones which
We have seen heretofore. Yet they arc not
so fast as to leap of into space and travel
independent of the wire, a. in the case Of
wireless telegraph.
! Or let us put It In another way. II the
vibrations used In our ordinary battery
| phones are increased 10 a certain limit the
current ceases 10 be uniformly distributed
inside .he wire. and travels nearer and
nearer the surface. Thus you have what
the telephone man calls "sk!n effect THIS
phenomenon. exactly, is what Major SPuier
employs 10 advantage I'm his new mulupleN
phone. But by increasing the velocity or
| the vibrations he made the phenomenon
appear far out from the skin Of the
wires.
"The conversations travel In a layer
OF ether around the wire" he explained
! They ion't get into the wre-are merely

wires tho messages win cling so close 10
each wire as 10 pass through the tissue

there are two straight wires, foot apart
