Nathan B.
Stubblefield (November 22, 1860 -
March 28, 1928) was an American inventor
and Kentucky-born Educator and founder of
Teléph-on-délgreen
Industrial School..
Teléph-on-délgreen, built on
his 85 acre melon farmland is now the
campus of Murray State University, Murray,
Kentucky. The peaches, apples, watermelons
and other crops that Nathan
Stubblefield grew on
Teléph-on-délgreen, were not
only a source of pride, but it was the
watermelon that held special symbolism to
his EMW RF inventions, and All-in-One
Radio Patent, 1908.
The Nathan B. Stubblefield 1892 Wireless
Telephone system, hereinafter,
called NBS WiFi, or simply NBS, had at
least for a while, a few advantages over
and above his wireless conpetitors. The
big difference between his and theirs, NBS
could send voice, and the Edison, Tesla,
Marconi, and Fessenden transmiters
couldn't.
To compete against their existing patented
EMW spark induction coils that doubled as
both an aerial and a transmitter of
dampened or spark EMW RF signals, NBS was
granted U.S. Patent for the electrolytic
earth battery coil patent in 1898.
What made the little NBS earth
electrolytic coils so unique, was when
they were attatched to a grounded aerial
they could imitate and do the same
multi-RF tasks as the Edison, Tesla, and
Marconi, spark coil devices.
Also what made the NBS induction coil so
sensible, was the broadcaster didn't need
the required tall100' mast tower, and
extraneous motor, (generator) system to
supply the high voltage current needed to
power their induction coils to produce the
RF spark signals emitted in space.
As it turns out, when his inert loop
antenna sitting above or near his physical
telephone microphone and speaker device
became energized by his EMW grounded
electrolytic patent, it became annimated.
His Wireless Telephone was then
ready for one way broadcasting, or could
act as a two-way wireless WiFi telephone
device, with options. (See to top
photo).
This unique set-up backboned his separate
and distinct scientific method of
transmitting RF voice signals through
space between land Vehicles,
ship-to-shore, moving trains, and office
and residential telephone customers, with
land-line telephone pole connections.

Today 100 years later, Cell Phone and WiFi
Internet users still transmit articulate
RF WiFi voice signals, as indicated in his
1908 patent drawings. The Wireless
Telephone RF transmitter/receiver,
was designed to utilize both the air waves
and land-lines, to reach the telephone
subscribers -- or one-way Wireless unit
with a speaker system. - Continue

Feature
(Excerpt
from)"The
SMART DAAF BOYS"
Continued
from above -
Because NBS knew he was living in a
copycat EMW world, he did something no
other inventor would ever do, he agreed to
invite all of his competitors to his 1902,
Washington, D.C. - Philadelphia
Demonstrations, to meet top Washington and
Kentucky officials. Not only did they all
show, but the government officials from
the U.S. Patent Office, Signal Corps, the
co-founder of General Electric, Edwin
Huston, Westinghouse, Tesla, Fessenden,
and Collins were all there witnessing the
first Wireless Telephony ship to shore
broadcast.
Four years later, on Christmas Eve, 1906,
the GE, Alexanderson - Fessenden team
reported to have accomplished the same
feat. Whereas Stubblefield used a battery
system to power his uninterrupted voice
broadcast, Fessenden used the GE
Alexanderson designed generator to power
his antenna system. Max Wien's technique
of muffling spark gaps by quenching spark
gaps prior to microphone activity and
during spark gap transmission, made his
broadcast possible. This was not a public
demonstration. CLICK

Nine
Years Before Marconi mastered sending
-- Dit dahs in his back yard, and
while DeForest was studying at Yale, as
early as 1885, Nathan B. Stubblefield, the
owner and inventor of his own telephone
company; and telephone system; --
developed a way to transmit the voice by
CW, as much as three miles-- by means of
his patented "earth battery."
---- By
allowing electricity to flow in one
direction only, these little coils
converted the very rapidly alternating
radio-frequency wave into a series of
pulses whose variations in strength,
(amplitude) --were in the audio-frequency
range to which earphones and the human ear
could respond. By 1892, he was
broadcasting voice -- and selling his
receiver to his customers and local
businesses. CLICK

1882 - 01 Nathan B.
Stubblefield demonstrated his ability to
send a signal across the Murray Courthouse
Square without wires. Note: Nathan's
wireless signal moved the needle of a
compass from north to south, to east-west,
the area where Nathan was standing with
his transmitter.
1882 - 03 Edison developed the first
central electric light power
station.
1882 - 05 Professor Amos E. Dolbear
was able to send signals over a distance
of a quarter of a mile without wires. Note
that Prof. Amos Dolbear preceded Hertz and
Marconi.
1885 -
Grover Cleveland: 1885-1889.
1885 -
From 1885 to 1913, Stubblefield
invented, developed, manufactured and
sold, both his wired mechanical telephone,
and his wireless telephone systems through
his own companies, partnerships or
corporations he owned shares of stock
in.
1885 -
In 1885, Stubblefield reportedly
succeeded in sending voice between two
parallel antennas by utilizing the same
principles Ward and Loomis developed in
sending damped signals but via a
low-frequency undamped electric wave
dispersion system. It was limited in
distance, but wireless (needs supporting
citation).

1886 -
Nine years before his contemporaries,
Marconi, Tesla and Fessenden mastered
sending Dit Dahs, (the Morse Code), Nathan
Stubblefield was the patent holder and
owner of his own telephone company,
(1886).
1886 -
Professor Amos Dolbear of Tufts
College obtained a patent for an induction
method of wireless
telegraph. 1887 - German
physicist Heinrich Hertz first
discovers Radio Waves. He transmitted an
electrical spark which was heard in a
receiving circuit a few meters away, thus
the term Hertzian Wave. Hertz demonstrated
that the velocity of radio waves equaled
the speed of light. The unit of frequency
was named in his honor. 1888

Nathan B. Stubblefield and Samual
Holcome patents their mechanical
"vibrating" telephone system. The first
permanent mechanical telephone
installation was in Murray, Kentucky to
demonstrate and sell franchised telephone
rights or territorial deeds around the
United
States.
1889 - Larynogophone:
Nathan B. Stubblefield - In 1889,
Stubblefield developed what was to have
been an improvement on his mechanical
telephone, and he renamed the device the
"Larynogophone." It was basically the
original mechanical telephone but with a
hearing tube and a bell added to his
copper wired telephone system that emitted
Sideband Electromagnetic Waves. 1892
- First Wireless Telephone Broadcasting
Demonstrations:
(Voice)
Nathan B. Stubblefield's first public
"wireless telephone" demonstration was
given in the town square of Murray,
Kentucky, a radius of about one half mile.
By connecting his telephone
apparatus to his newly invented
electrolytic coil earth battery -- he
transmitted and detected continuous
undamped electromagnetic waves, at a
radius of about one half mile;
Using
his grounded bare wired aerial system
connected to his loop coil antenna, placed
on top of his receiver -- he was able to
talk back and forth "without wires" to
others with a like telephone and loop
antenna, or broadcast voice and music to
those listening through a mono-earphone
piece; (The so-called Hertzian Wave, was
produced by coils that emitted sparks, and
could not transmit voice signals).
Rainey
T. Wells, who later became the founder and
president of Murray State University, was
one of the first persons to hear
Stubblefield's wireless voice
transmissions. Rainey became his assistant
in the 1892 exhibit. The public exhibits
demonstrated Nathan's;
1. Own Aerials;
2. Own Inductive Coupling To The
Aerial And Ground Circuits;
3. Own Tuning Coils and Detectors, to
Obtain the Desired Wavelength, and;
4. Employed his own power source
emitted from the earth that acted both as
a "hot spot" to transmit a continuous flow
of electricity to power his transmitter
signals through space, and as an unlimited
supply of electricity that simulated a
charged-up battery, ready to be used at
will. *(See Footnote.) Ice House. *
1892
- The first permanent wireless telephone
broadcasting installation was in January,
1892.The station was constructed in Murray,
Kentucky, by Stubblefield's
Teleph-on-del-green Industrial
College, now the campus where Murray
State University is located.
1894 - 02 The first
permanent wired telephone exchange
switchboard installation in Murray,
Kentucky, was on February 12, 1894. The
telephone service was constructed in
Murray, Kentucky, by the Nathan
Stubblefield Telephone Manufacturing Co.,
in the town square to work in conjunction
with his wireless telephone operation.

Wireless Telegraph Demonstration:
(Dit dahs

Guglielmo Marconi - In the spring of 1895,
what Nathan B. Stubblefield did with
wireless voice transmission in 1892,
Guglielmo Marconi did with dots and dashes
utilizing damped electromagnetic waves
emitted by his Ruhmkorff coils (see 1897).
He discovered that his "black box"
utilizing the Ruhmkorff coil, could send
controlled messages, by touching two
electrically charged wires together in a
dit dah manner - over distances far
greater than those from his villa to the
garden -- distances which would travel
more than a mile. It was Marconi's great
basic invention. Like Stubblefield, he
built an aerial -- an antenna which he
connected to one side of the spark gap.
(Hertz had merely used a horizontal rod
ending in a plate). The aerial was a metal
cylinder atop a pole. He connected the
other side of the spark gap to a ground --
at first, a copper plate lying in the
ground. The receiver also got an aerial
and ground.

Coil, the Induction Coil, Earth Battery,
Undamped Transmitting Coils, The
Stubblefield Electrolytic Detector.
Stubblefield's
grounded bare wired Antenna System was
part of his system to transmit continuous
voice or telegraph signals without wires
through a single aerial tower. The first
permanent wireless telephone broadcasting
installation in the world, (the precursor
to AM Radio) -- was erected by
Stubblefield's Teleph-on-del-green
Industrial College, in January, 1892. The
location is now part of Murray State
University, Murray, Kentucky, U.S.A. The
transmitter and receivers were usually
placed 200 feet apart for demonstrations.
The electromagnetic coils were also the
precursor for today's "Firewire" and
battery operated implants in today's world
of broadband streaming video and
electro/heartstimulus
technology.

The "Kingsbury Commitment."
- American Telephone and Telegraph
(AT&T) began buying up rivals. But
AT&T's acquisitions troubled federal
authorities, which began considering
antitrust action. This prompted AT&T's
company officials to propose, a
self-serving anti-monopoly unit, that
subsequently became known as the
"Kingsbury Commitment." On December 19,
1913, AT&T agreed to sell $30 million
of its Western Union stock and to allow
competitors to interconnect with its
network. The company also pledged that for
every new local system acquired, it would
sell an equal share of lines to rivals.
The Kingsbury Commitment was wholly in
keeping with the monopolizing of both
wired and wireless strategy of
AT&T;
and the preserving of consumer confidence
by the use of Takeovers; Buyouts; and
mergers of troubled competitive
"look-a-Likes".

The original development of single
sideband came about because of certain
limitations in radio telephone circuits.
Experiments were first conducted by Nathan
B. Stubblefield and Major Squire in 1908,
and then Squire and John R. Carson of the
Bell Research and Development Labs, and
the American Telephone & Telegraph
Company in 1915.

Editor's Patent Notes
----It is now
assumed, that after his public
demonstrations in 1892 and 1902, in
Murray, Kentucky and later on the Potomac
River in Washington, D.C., the SMART-DAAF
BOYS and the rest of the world would have
become aware of his feats -- to send voice
without the use of wires.
----
The radio voice demonstrations made
by Stubblefield, were made 14 years before
Alexanderson and Fessenden's, 1906 radio
demonstration. Stubblefield used his
electrolytic transmitting and detector
devices, (his ground batteries) to relay
-- his radio signal, as Fessenden did with
his own "exciters" -- and AT&T did
with Maj. Gen. Squier's multiplex, wired
wireless system and 29 relay stations,
(Please see Figure 3.19). Stubblefield ran
his largest transmitter at approximately
250 meters.
---- At
times, to extend the distance of his
broadcast, he would secretly bury a string
of his "earth" ground electrolytic
transmitter/detectors -- to relay his
signals. In short, he was modulating the
ground's electrical potential, changing it
from an electrical "sinkhole" -- to an
electrical transmitting source as an
engineer would do at any modern-day, AM
transmitter antenna site.
Before his 1908,
"All-in-One" patent was issued, (that
granted him the rights for both
Hi-frequency and Wired Wireless or
Guided-wave system for the use of
broadcasting to all moving vehicles, ships
and trains) - he was asked to describe the
differences in his transmitting stationary
aerial; the horizontal aerial having its
opposite stretches or sides extending
along the opposite sides of the path of
travel of the vehicle; and the loop
antenna coil attached to the vehicle -
from other patents.
---- He
simple explained to the patent examiners
of the impossibilities to broadcast radio
waves with their coils, because, as he put
it, they did not have the proper wire, and
would have died from "high frequency
kickback". High frequency quickly heats
insulation. [Editors Note: A microwave
oven works on the same principle. In a few
minutes, the insulation inside the
generator or coil grew so hot, that the
coils caught fire.]
What saved the day in
the granting of the patent on his 1908
wireless telegraphy system, was the
transmission coil described in his 10-
year-old, 1898 "earth battery" patent. It
should be also noted, that Stubblefield's,
loop "antenna" was covered within the
patent. The loop antenna was designed to
be used with radios installed in moving
vehicles that could not be grounded, such
as: airplanes, ships and automobiles.
----
Residents and customers of
Stubblefield's telephone company, in the
small town of Murray, used similar
wireless equipment in their business
telephone service and wireless burglar
alarm systems -- installed by Stubblefield
since 1895.
---- The
United States Army and AT&T first used
the combined system during World War I, to
guarantee articulate voice reception; if
the transmitting aerial was knocked out,
the wired wireless system would continue
to operate until the aerial could be
repaired.
The First Wireless
Telephone Company to commercially exploit
the invention, was established in 1902,
and folded in 1927. Stubblefield became a
stock holder, officer and director of the
Wireless Telephone Company of America.
---- It is
obvious his demonstrations in Philadelphia
and Washington, D.C., created more
interest in the device from the SMART-DAAF
BOYS and stock promoters, than history
books. Yet it is here that we realize that
the following SMART-DAAF BOYS were the
ones that perfected Stubblefield's basic
principles of AM radio broadcasting, as we
know it today.
