Improvements in Phonographs.
A communication from BELA STEINER, of Josefspatz 11, Budapest, in the
Kingdom of Hungary, Gentleman.
1, WILLIAM LLOYD WISE of No. 46 Lincoln's Inn Fields in the County of
London, Consulting Engineer and Patent Agent, do hereby declare the nature of
this invention to be as follows:-
This invention has reference to improvements in phonographs and has for its
object to increase or strengthen the sound obtained when a phonogram is
reproduced.
This object is attained by arranging the diaphragm not in a horizontal or inclined
position as heretofore, but in a vertical position, in such a manner that its vibrations
are delivered to listeners from both sides of it.
The reproducing point, which is actuated by the diaphragm when recording a
phonogram, and actuates the diaphragm when reproducing a phonogram, is attached
to one end or arm of a bent or angular lever which is so pivoted to the frame
carrying the diaphragm as to be capable of partial rotation, another end or arm of
the said lever being secured to the diaphragm. The diaphragm is arranged
vertically, and perpendicularly to the axis of the phonogram cylinder. In this way,
the recording of a phonogram is effected, not as heretofore, by more or less deep
impressions in the surface of the cylinder, but by the recording point penetrating
to a certain extent into the material of the cylinder, vibrating in the direction of
the axis of the cylinder, and tracing thereon an undulated line which constitutes
the phonogram.
In the accompanying drawings,
Fig. 1 is a side elevation, partly in section shewing the diaphragm, the frame for
carrying the same, the lever and recording point carried thereby and part of the
phonogram cylinder, arranged according to this invention.
Fig. 2 is a section through the line of Fig. 1.
a is the diaphragm of the phonograph arranged vertically and perpendicularly to
the axis of the phonogram cylinder b; it is attached to the frame d by a ring c.
This frame d is completed on cach side by tube attachments f, g, to which are
secured the bells or ear-tubes. To the centre of the diaphragm a, at one side
thereof, is attached the upper end of a transmitting arm which passes through a
slot in the frame d, and is secured to a shaft k, which is pivoted so as to turn
easily, between the points of two pivots or screws 1, fixed to a hoop or carrier m
attached to the frame of the diaphragm. Fixed to the shaft & is another arm k¹
which carries the recording point n. The vibrations of the diaphragm cause the
recording point to oscillate in the direction of the axis of the cylinder, and to impress
the surface thereof so that when the same is revolving, a visible undulated line
which constitutes the phonogram is produced thereon. It is obvious that the
recording point n must, to a certain extent, enter or cut into the material of the
cylinder.
It will be seen that the arm of the shaft k, and the arm k¹ carrying the recording
point, work together after the manner of a bent or angular lever, and can be replaced
by one having a different form to that shown.

Improvements in Phonographs.
A communication from BELA STEINER, of Josefspatz 11, Budapest, in the
Kingdom of Hungary, Gentleman.
I, WILLIAM LLOYD WISE of No. 46 Lincoln's Inn Fields in the County of
London, Consulting Engineer and Patent Agent, 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 :-
This invention has reference to improvements in phonographs and has for its
object to increase or strengthen the sound obtained when a phonogram is
reproduced.
This object is attained by arranging the diaphragm not in a horizontal or inclined
position as heretofore, but in a vertical position, in such a manner that its vibrations
are delivered to listeners from both sides of it.
The reproducing point, which is actuated by the diaphragm when recording a
phonogram, and actuates the diaphragm when reproducing a phonogram, is
attached to one end or arm of a bent or angular lever which is so pivoted
to the frame carrying. the diaphragm as to be capable of partial rotation,
another end or arm of the said lever being secured to the diaphragm. The
diaphragm is arranged vertically, and perpendicularly to the axis of the phono-
gram cylinder. In this way, the recording of a phonogram is effected, not as
heretofore, by more or less deep impressions in the surface of the cylinder, but by
the recording point penetrating to a certain extent into the material of the cylinder,
vibrating in the direction of the axis of the cylinder, and tracing thereon an
undulated line which constitutes the phonogram.
In the drawings left with my Provisional Specification
Fig. 1 is a side elevation, partly in section shewing the diaphragm, the frame for
carrying the same, the lever and recording point carried thereby and part of the
phonogram cylinder, arranged according to this invention.
Fig. 2 is a section through the line of Fig. 1.
a is the diaphragm of the phonograph arranged vertically and perpendicularly to
the axis of the phonogram cylinder ; it is attached to the frame d by a ring 6.
This frame d is completed on each side by tube attachments f, g, to which are
secured the bells or car-tubes. To the centre of the diaphragm a, at one side
thereof, is attached the upper end of a transmitting arm which passes through a
slot d in the frame d, and is secured to a shaft k, which is pivoted so as to turn
easily, between the points of two pivots or screws 1, fixed to a hoop or carrier m
attached to the frame of the diaphragm. Fixed to the shaft is another arm ¹
which carries the recording point n. The vibrations of the diaphragm cause the
recording point to oscillate in the direction of the axis of the cylinder, and to
impress the surface thereof so that when the same is revolving, a visible undulated
line which constitutes the phonogram is produced thereon. It is obvious that the
recording point n must, to a certain extent, enter or cut into the material of the
cylinder.
It will be seen that the arm of the shaft k, and the arm carrying the
recording point, work together after the manner of a bent or angular lever, and
can be replaced by one having a different form to that shown.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
1. In a phonograph, a vertical diaphragm a supported by a frame extending to
cach side thereof, the said diaphragm being arranged perpendicular to the axis of
the recording cylinder so that sounds are rendered more audible whilst a phonogram
in boire nonrodead

page_text: 2. In a phonograph, a bent or angular lever, or arrangement of parts h, k, k¹
pivoted or connected to the frame carrying the diaphragm, so as to be capable of
vibration in a rotary sense, and connected to the diaphragm so as through the
medium of the recording point n to record the vibrations of the diaphragm a in the
form of an undulated line on the surface of the phonogram cylinder.
