PROVISIONAL SPECIFICATION.
Improvements in Phonographs.
JOHN ORME 65 Barbican London E.C. Scientific Apparatus Manufacturer, do
hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide a simple apparatus for receiving
impressions made by sounds and of emitting sounds similar to those received. The
apparatus consists of a series of wheels capable of containing a strip of paper,
tinfoil or its equivalent, arranged upon a stand to which is attached a moveable
diaphgram and mouthpeice. In the centre of the diaphgram a metal or other
suitable point is so arranged as that when sounds cause the diaphgram to vibrate
the point impinges upon the strip of material passing at that time over the wheel
directly under the point and impressions are registered upon the strip. The strip
is coiled upon a wheel its free end being passed over the wheel directly under the
point in the diaphgram and fastened to a second wheel which upon being revolved
uncoils the strip from the first wheel and coils it upon itself: notion being imparted
by means of a handle attached to the wheel or by other suitable force such as a
pulley and weight, clock work and spring, or electrical motor.
After the impressions have been received upon the strip, the diaphgram is moved
forward, the strip coiled back into its first position and the diaphgram again placed
so that its point impinges upon the strip.
Upon causing the strip to pass under the point as it passed in receiving the
impressions, sounds will be emitted from the diaphgram similar to those which it
received.

COMPLETE SPECIFICATION.
Improvements in Phonographs.
JOHN ORME 65 Barbican London E.C. Scientific Apparatus Manufacturer do
hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
The object of my invention is to provide a simple apparatus capable of
receiving impressions made by sounds, & of emitting sounds similar to those
received.
The apparatus consists of a series of wheels (G. N. O.) capable of containing
a strip of paper, tinfoil, or its equivalent arranged upon a stand to which is
attached a moveable mouth peice (A) & diaphgram (B) with a needle point (E),
as used in Edison's & other phonographs.
I prefer to arrange my wheels which carry the strip of paper, in a similar
manner to the arrangements of a Morse printing telegraph instrument, which
arrangement is well known, whereby the strip of paper or tinfoil which is to
receive the impressions caused by the vibrations of the diaphgram & needle, is
made to pass continuously over a wheel (G) placed in contact with the point of the
needle (E) so that when sounds cause the diaphgram (B) to vibrate the needle
registers a series of impressions upon the strip passing under it.
I prefer to use a third wheel (O) upon which the impressed paper may be
coiled, so that the paper is kept free from creases & the impressions remain
uniniured.

page_text: Motion is imparted to the wheels which carry the paper strip by clockwork (I H)
or by small electric moter; or a handle may be attached to work the wheels by
hand, or a weight & pulley or other suitable force may be used.
After the impressions have been received upon the strip, the diaphgram (B) is
moved forward, the strip coiled back into its first position & the diaphgram
again placed so that the needle point can follow the impressions made on the
strip of paper or tinfoil; when, upon setting the wheels in motion sounds will
be emitted from the diaphgram similar to those which it received.
The drawings attached hereto show the particulars of the invention, but I do not
confine myself to the exact design therein shown, as the principle may be applied in
various other forms of construction.
The mouthpeice (A) & diaphgram (B) are carried upon a support hinged at (K)
which thus readily permits of the diaphgram being moved forward. The needle (E)
is fastened to a spring (D) & a peice of india rubber (C) fastened so that it forms
a cushion between the spring (D) & the diaphgram (B).
A second spring (F) may be used to give greater steadiness to the needle, but it
is not absolutely necessary.
The screws (L) & (M) are for purposes of fine adjustment.
Fig. 1 is a vertical section, Fig. 2 is a front veiw of the instrument.
I make no claim to the diaphgram & point, nor to the arrangement of the
wheels, and these are in use for other purposes & are well known at the
present day.
Having now particularly described & ascertained the nature of my said inven-
tion & in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination as described of a diaphgram & point with a series of wheels
for using a strip of paper or tinfoil for the purpose of receiving, recording &
emitting sounds.
