PROVISIONAL SPECIFICATION.
An Instrument or Means for the Combined Purposes of Transmitting
and Recording Speech or other Sounds.
I HENRY EDMUNDS of 10 Hatton Garden in the City of London Electrical
Engineer do hereby declare the nature of my said Invention to be as follows:-
:-
My Invention has for its object to provide an instrument which can be used for
the combined purposes of transmitting and recording speech or other sounds that is
to say that it is adapted for use as a telephone and at the same time to make a record
for subsequent reproduction of the speech or other sounds after the manner of what
is known as a Graphophone. With this object I provide in connection with the
transmitter of any suitable telephonic instrument a passage or tube by which the
speech or other sound is conducted thereto there being situated in or in connection
with this passage or tube a diaphragm for operating the groove making device of a
Graphophone. A most convenient form of the apparatus consists of a tube leading
to a junction piece in which is the Graphophone diaphragm and leading from this
junction piece is another tube opening at the other end before the diaphragm of a
telephonic transmitter.

COMPLETE SPECIFICATION.
An Instrument or Means for the Combined Purposes of Transmitting
and Recording Speech or other Sounds.
I HENRY EDMUNDS of 10 Hatton Garden in the City of London Electrical Engineer
do hereby declare the nature of my said Invention and in what manner the same is
to be performed to be particularly described and ascertained in and by the following
statement:-
My Invention has for its object to provide an instrument which can be used for the
combined purposes of transmitting and recording speech or other sounds that is to say
that it is adapted for use as a telephone and at the same time to make a record for
subsequent reproduction of the speech or other sounds after the manner of what is
known as a "Graphophone." With this object I provide in connection with any
suitable telephonic instrument a passage or tube by which the speech or other sound
is conducted thereto there being situated in, or in connection with, this passage or
tube a diaphragm for operating the groove making device of a Graphophone or other
sound recording instrument. The accompanying drawing represents in perspective a
convenient arrangement of apparatus for carrying out my Invention, A being a
telephonic instrument and B a "Graphophone." is a tube leading to a junction
piece Din which is the diaphragm which carries the groove making device or style
of the Gaphophone and leading from this junction piece is another tube E communi-
cating with the tube C. The outer end of the tube E is supported in a clamp or
support F fitted so as to be capable of being adjusted in position on a bracket G
fixed to a wall or other suitable support in proximity to the telephonic instrument A
or to the instrument itself. The open end of the tube E is shewn as being held by
the clamp F opposite the diaphragm of the transmitter of the telephonic instrument
so that when the tube C is spoken into or sounds are introduced therein through the
mouth piece C the sound waves will be directed first onto the diaphragm of the
Graphophone" in the junction piece D and then will pass out of the tube E and
act against the diaphragm of the transmitter A so that by operating the recording
"

page_text: cylinder B of the Graphophone while using the telephone, the speech or sounds
being transmitted through the telephone may be simultaneously recorded in the
Graphophone for subsequent reproduction when required.
From the foregoing description it will be evident how the device can be arranged
to receive or transmit and record speech as desired.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is―
An instrument or means for the combined purpose of transmitting and recording
of speech or other sounds consisting of the combination as described of a telephonic
instrument and a Graphophone or sound recording apparatus substantially as herein-
before described.
