" Know that me, Roberto Landell de
Moura, citizen of the Republic of Brasil resident in the district
of Manhattan of New York city, New York State, invented a new Wave
Transmitter, that makes the following specifications:
My invention is related to Message Transmissions,
from a point to another, without the aid of wires, or concisely the communicating
through space.
Fastened in the superior extremity
of the cover (A') a flexible tube exists (C) with a mouth (c).
To whom it may concern:"
It has the objective of producing better results with simplified
apparatus, using certains principles that I discovered. Up to now, when
we had to transmit signals, the transmission was made by means of apparatus
of manual operation. In some cases, these were substituted by automatic
mechanisms; but the handling of such mechanisms, or the manipulation of
a key, demanding certain abilities and experience of the operator. In agreement
with my invention, I produce, firstly, Electrics
Oscillations and a Light Trembling, by means
of Sound Vibrations,
it can be of the Human Voice or
others sounds.
I use these Electric
or Luminous Oscillations,
so produced, to telephone or
to telegraph
through space . In such transmissions, and especially telephoning, I can
use inventions similar to the ones that I described in my previous solicitation,
protocoled in OCT 04 - 1901, series N.77.576.To produce the two species
of mentioned oscillations I invented a disposition of circuits and of certains
apparatus that I denominated "phonetic switch". *Obs:Web
comments: (a electro mechanical microphone).
My phonetic
switch consists, essentially, of a pair of
contacts capable of reproducing the sounds vibrations
, or the vibrations from any source that can control the primary circuit
of a high frequency induction coil, this primary is tied up to the primary
of a Ruhmkorff coil
for transmission.
The
Sound Vibrations on the Fonetic
Switch are transformed in Electrics
or Light Waves,
the one which, passing to the receiving station, are received and act on
appropriate apparatus, by means of which they are perceptible with the
use of a Phone Receiver,
of a lamp, of
a Recording Morse, or similar thing. My invention
is in full detail described in the following specifications, and illustraded
in the enclosed drawings.
In relationship to fig.1 it
is a cut of my phonetic switch ,
with the whole parts represented. In 2 the
illustration represents a regulatory key for the nucleus of the induction
coil. In 5 the circuits transmitters are
represented with the apparatus; represented in their places. In 1 we
have the box with non conductor material, and A' is the cover. This cover
is made to contain a Resonant Chamber,
whose base has a perforated disk
A2 and is sustained by the receptacle there is a diaphragm (a), having
in their central point a slight depression. (a').
Placed inside of the receptacle
and supported in appropriate projections, there is an Induction Coil, that
has the primary (d) and the secondary (d') coiled around of the iron nucleus
(d2).This nucleus is hollow, and in its interior a central axis exists
(B) supported in its superior extremity by the perforated extremity of
the nucleus and in its inferior extremity, it is connected inwardly by the
nut (b) screwed in the inferior extremity of the nucleus, and the guide
(b4). The axis has a head (B') which can be manipulated. The function of
the adjustment is to allow that the narrow opening of air, between the
extremety axis, in (b2) and the diaphragm (a), in (a'), be in such an arranged
way that the vibrations of the articulated words produces a continuous,
fast and regular movement, and interrupt the circuit. By means of key K
(represented in 2), the nut (b) it can be screwed when the axis is adjusted,
introducing the stems (k) and (k4), of the key in the holes (b3) of the
nut.
To use the apparatus,
the operator speaks in agreement with a established code or in any
other way, through the mouth (c).The propagation
of the Sound Waves through the tube, passing between of the central
opening of the cover (A2) act over the diaphragm (a), producing a corresponding
vibration, and in consequence if the adjustments had been correctly done,
a fast series of contacts and interruptions
or successive contacts will happen
between the diafragm
and the extremity of
(b2), corresponding
the frequency
to the waves that were produced.
These contacts
and interruptions determine pulses
or current variations
, in the secondary circuits 12, being irradiated
by the Antenna.
The production and the interruptions
of contacts have as consequence, to produce current pulsations in the primary
coil, corresponding very aproximately to
the voice tones or the sounds produced.
Certainly, it is impossible to
obtain an adjustment of such perfect contact that reproduces all the harmonics
and turn a perfect articulation, but in the other hand, in order to get
the positive effects, of discharge, the other that I will refer now I think to be
best, other than the simple change of the circuit resistence.
It is not necessary to say that I can adjust the contacts in
such a way to produce constant contacts and variable pressure, requirements
so that the microphone will work perfectly; but with practical intention, I
think that is better to produce the pulses in the way that I described.
Considering now (5), I will describe
the connections of my apparatus, to obtain an effective system.
F is a Ruhmkorff coil or any
other induction coil of high potency, adjusted in way to produce a flash
of certain length, - let us say of about a 1/4 inch or more.
The primary of this coil (f) is tied up to the the circuit 15 and 16, that
includes the main battery M and the phonetic switch. The secondary coil,
marked (f') is connected by the wires 7 and 8 to the terminals 21 and 20
to the
irradiant wires, that can be
of common form or any aerial conductor, with or without terminal
grounded in one of the sides.
A terminal pair (11) and
(12) to produce flash, is foreseen, to be inserted in the circuit (7) (8),
by the simple closing of the switch (S'). It is also linked to the secondary
circuit, a capacitor of convenient capacity. The primary circuit (15) (16)
is going from the Ruhmkorff coil to the primary terminals of the induction
coil (D), in the phonetic switch.
The secondary coil (d') is tied
up to a local circuit (19), that contains a Phone
Receiver (T), and the primary circuit includes
a lamp, that can be used to transmit or to receive messages.
There is too a capacitor (G) of convenient capacity, inserted in the primary
circuit. The way to use the described system,
is the following: To
transmit electromagnetic waves corresponding to the Sound
Vibrations, the key (S') is closed and the
the key (S) is opened, and the operator starts to produce the wanted sounds,
by means of the fonetic switch. A
pulses succesions is so produced in the primary circuit coil (F), whose
effect is increased by the presence of the capacitor (G), that absorbs
the current excess, it contribute to the fast demagnetization of the
induction coil and still disable the the production of flashes between
the diaphragm and the point of the axis.
These pulses in the primary
are very fast , when the adjustments are appropriately done, they produce pulses
of high potential in the secondary.
To produce Light
Oscillations by means of the switch, in the
transmitter station, I use the natural human
voice, because the trembling produced corresponding
in form and frequency to the initial sounds, and being these
sounds produced in a convenient way with the aid of adequate apparatus,
in the receiving station, they allow the recognition more ou less perfect
of the original sounds, and seen as a lot of words or tones can be
recognized by its intrinsic value, as much as for any value that can be
lent by means of any arbitrary code, an enough number of different words
can be selected, to constitute a complete and very efficient code.
Of course other sources of soundvibrations can be used to substitute the human voice. So, to produce electricoscillations by means of the same switch, it can be used in the transmitter
station,
a constituted source of sounds
by a musical instrument similar to a small organ , having a group of sheets
or acoustic tubes tied up to the mouth (C). By the strong diaphragm vibration,
it produces light oscillations or
electricity that can be received, after transmitted, by means of any
sensitive apparatus. In addition to this transmission method by means of
electromagnet or
luminous waves, as I said, some of the particularities
hereby described they can be used together with my other systems.
In one of these systems, I use waves
or intermittent signals of light , to transmit codes signals.
In the present case I can
use the lamp (e), in a similar way, producing the initial variations of
current by means of the phonetic switch. If
the light pulsations are fast, the adjustment of the terminals and diaphragm can be regulated,
untill the width of the variations is enough to eliminate all the tones
less the fundamental ones. In fact more weight can be given to the diaphragm,
if it necessary, or its pulsations can be in another way, retarded.
In the case of the transmission to be done
by light waves , I use reflector and I can also use screens of several
materials, such as sheets of colored glass, and it is possible to substitute
the lamp indicated by a cathodic lamp, of the type described in my other
solicitation, or other light types.
Observe that the most important
and, in fact, the essential aspect of my invention is the employment of
a transmitter that turns on and and off by the effect of the sound vibrations,
doing the light waves or transmitted eletromagnectics waves corresponding
, in a very approximate way, to the sound waves which are produced.
