An Aurophone.
We, SIGISMUND FREDERICK HARTE, Aurist, and WILLIAM HENRY FASSETT,
Merchant, both of 39 Baker Street, London, do hereby declare the nature of this
invention to be as follows:-
The object of our invention is to provide a sound magnifier to be used by persons
suffering from deafness.
The invention consists
(1) In a heart-shaped bowl or sound-receiver about 7ths of an inch in length
and ths of an inch in width, with concave indents on either side below the apex, and
a hole about 3nds of an inch in diameter in the centre. The whole piece is con-
structed of thin gold, or other suitable material.
(2) The concave part of the heart-shaped bowl may be enameled with flesh-
coloured enamel to avoid notice.
(3) A hollow tube about of an inch in length, and th of an inch in diameter
also constructed of gold or other suitable material is soldered at one end, to the
convex side of the bowl over the bole before mentioned.
(4) A pin formed of gilded steel or other suitable material about ths of an inch
in length is soldered to the inside wall of the hollow tube commencing from the base
of the concave part of the bowl.
(5) On the opposite point of the gilded steel pin a round rubber disk about 3rd of
an inch in diameter is fastened at its centre with brass and rubber washers facing the
tube and the convex part of the bowl.
The improved aurophone thus complete acts as follows when inserted in the
auditory channel of the ear.
The tube expands the ear-walls and divides the chain of bones, whilst the sound-
receiver transmits and magnifies all sounds and air waves through the tube and over
the gilded steel pin into the rubber disk.

COMPLETE SPECIFICATION.
An Aurophone.
We, SIGISMUND FREDERICK HARTE, Aurist, and WILLIAM HENRY FASSETT,
Merchant, both of 39 Baker Street, London, 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 this invention is to provide an instrument, belonging to the class of
instruments known as Aurophones, to be inserted in the ears of persons suffering
from deafness, for the purpose of magnifying or increasing sound.
The appliance thus used consists of four parts connected together, which I will now
proceed to describe with reference to the accompanying drawings, in which Fig. 1
shews a perspective view of the instrument drawn about double the usual size.
Fig. 2 shews a plan of the exterior concave side of the sound receiver or dish a.
Fig. 3 shews a sectional elevation of the entire appliance.
At one end of the instrument is the small concave dish or bowl a, the actual size of
which is about seven-sixteenth's of an inch in length, and three-eighth's of an inch in
width. This dish is the external sound receiver and it is formed of gold or other
suitable material.

page_text: It has indentations on three sides and a hole 6,about three-thirty seconds of an inch
in diameter in the centre. The interior of the dish may be enamelled with flesh-
colored enamel to avoid notice. Extending from the hole in the centre of the dish a,
is the small tube c..
At the opposite end of the instrument is the thin rubber disk d, about one-third of
an inch in diameter.
These two parts are connected by the fine wire e, formed by preference of gilded
steel or other suitable material. The point of juncture of the wire with the disk is
strengthened by washers f, placed between the flanges on the wire, one on either side
of the disk, so as to form a secure joint. The wire e, is soldered to the tube C,
terminates at the hole b.
and
The improved Aurophone when thus constructed is inserted in the auditory channel
of the ear, the india rubber disk d, being inside, and the dish a, near the outside of
the ear.
The instrument acts as follows. The tube fits the ear-walls closely and divides the
chain of bones, whilst the sound receiver transmits and magnifies all sounds and air
waves through the tube and over the gilded steel wire into the rubber disk.
Having now particularly described and ascertained the nature of our said Inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
The combination of the indented concave dish a, the tube c, the wire e, and the
india-rubber disk d, and washers f, in an appliance for the relief and cure of
deafness, as herein explained and set forth.
