effect record ~ the inventor says:
These depend in a great measure
upon the volume Of sound desired in the
reproduction If the reproduction is to
be made audible to an audience, consid-
erable force Is requisite in the original
utterauce; il for the individual ear only
the ordinary converse tional tone (eycn
II whisper has been reproduced). In
both cases the original utterances are
delivered directly in the mouthpiecc of
the instrument. An audible reproduce
ion may, however, be had by speaking
at the instrument from distance Ui
from two to three feet in loud tone.
The application OF a tlaring tube or fun
mel to collect the sound waves and the
construction Of an. especially delicate
diaphragm and embossing point, etc,
are the simple means which suggest
themselves to effect this. The writer
has not as yet given this stage of the
Development much attention, but sees
no practical difficulty in gathering up
and retaining sectional part of the
sound waves dif'used about the original
s"urce Of say three feet sufficiently re-
moved not to be annoying to IL speaker
or a singer"
The actual practical results obtained
from the phonograph may be set down
as follows; Tie captivity, permanent
retention and reproduction at will with
original characteristics, Of all sound
waves heretofore designated MS "fugit-
i've" The transmission of captive
sounds in material form for purposes OF
communication or merchantablc goods.
The indefinite multiplication and preser-
vatitn OF sounds, without regard to the
existence Of the original source, and the
captivation of sounds with or without
the knowledge or consent of the source
of their origin. Among the more inn
portant prospective applications of the
phenograph may be mentioned letter
writing and other forms OF dictation,
books, education, reading, music, family
record and such electrotype applications
as books, musical boxes, toys, clocks, al
vertising and signaling apparatus,
speeches, etc.
THE LETTER WRITER PHoNoGRAPH
"The apparatus now being perfected
in mechanical detail will be the standard
photograph. The general principles OF
constructiorsare fiat plate or disk.
with spiral groove on the face, oper-
ated by clockwork underneath the plate,
the grooves are cut very closely together
so as to give the greatest length to each
inch Of surface IA close calculation gives
as the capacity of each sheet of foil, upon
which the record is had, in the neIghbor-
hood of forty thousand words"
"rhe practical application of this form
Of phonograph for communications is
very simple, A sheet of foil is placed
in the phonograph, the clockwork is set
in motion and the matter dictated into
the moutbpiece without other effort than
when debating to a steuographer. 1t IS
then removed and placed in u suitable
form of envelope and sent through the
ordinary channels to the corr espondent
for whom designed. He placing it upon
his phonograph, starts the clockwork
and listens to what his correspondent
has to say
BOOKS, MUSIC, RECORDS, ETC.
Books may be read by the charitable
inclined professional reader, or by such
readers especially employed for that pur-
pose, and the record OF such book used
IN THE asylum Tor tue Dllnu, hospitals,
the sick chamber, or even with great
profit and amusement by the lady or
gentleman whose eyes and hands may be
otherwise employed; or again, because Of
the greater enjoyment to be had from a
book when read by an elocutionist than
when read by the average reader. The
ordinary record sheet repeating this
book from fifty to hundred times us it
will, would command price that would
pay the original reader well for the
slightly increased difficulty in reading
it loud in the phonograph.
