AN ARTIFICIAL EAR DRUM OR INSTRUMENT FOR THE RELIEF OF DEAFNESS
Year: 1885

page_text: I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Win. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of the said Invention for "AN ARTIFICIAL
EAR DRUM OR INSTRUMENT FOR THE RELIEF OF DEAFNESS" a communication to
me from abroad by John Henry Nicholson of the City, County and State of New
York, United States of America, Publisher to be as follows:-
The object of this invention is to provide an artificial ear drum to be used by
deaf persons.
The apparatus is constructed of a magnatised steel rod carrying a soft rubber
disc on each end and provided with a gold or silver covering, the discs being held
in place by gold washers and provided with ventilating apertures and notches.
The tube or covering fits closely on the rod or the rod can be gold or silver plated
and the said rod is provided at one end, with a flat head or button. A rubber
washer on the rod rests against the inner surface of the head or button and against
it is placed a thin rubber disc which is provided with ventilating apertures and with
ventilating notches in its edge. A gold washer mounted on the rod holds the rubber
washer and the disc on the head.
On the opposite end of the rod a thin soft rubber disc provided with ventilating
notches in its edge is held by two gold washers on opposite sides of the
rubber disc.
One end of the device is inserted in the auditory channel of the ear until the
head or button adjoins the delicate organs of the ear, the other rubber disc being
held in the outside part of the ear just out of sight but within reach of the fingers
to permit of inserting and withdrawing the instrument.
The magnatized rod receives the impulses of the air wave and carries them along
and discharges them to the nerve of the ear with slight magnetic force causing the
organs of the ear to take on increased action. The rubber discs hold the device in
place in the ear and protect the delicate organs from coming in contact with the
gold parts of the device. The outer gold washer or disc receives the sound waves
and conveys them to the magnetic rod.

An Artificial Ear Drum or Instrument for the Relief of Deafness..
I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of this Invention (a communication to me
from abroad by John Henry Nicholson (Publisher) of the City, County and State
of New York, United States of America, 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 a new and improved artificial ear drum
to be used by deaf persons.
The invention consists in an artificial ear drum constructed of a magnetized steel
rod carrying a soft rubber disc on each end.
The steel rod is provided with a gold or silver covering and the discs are held in
place by gold washers and provided with ventilating apertures and notches.
Reference is to be had to the accompanying drawings forming part of this
specification in which similar letters of reference indicate corresponding parts in all
the figures.
Figure 1 is a longitudinal sectional elevation of the improved artificial ear drum.
Figure 2 is an outer face view of the rubber disc to be placed in the interior part
of the auditory channel.
Figure 3 is an outer face view of the rubber disc to be placed in the inner end of
the auditory channel.
A magnetized steel rod A is surrounded by a closely fitting gold or silver tube B
or the rod can be gold or silver plated and the said rod is provided at one end with
a flat head or button C.
A rubber washer D mounted on the rod rests against the inner surface of the
head C and against it a thin rubber disc H is placed which is provided with
ventilating apertures band with ventilating notches a in its edge. A gold
washer J mounted on the rod A, holds the rubber washer D and the disc H on the
head C.
On the opposite end of the rod A a thin soft rubber disc K provided with
ventilating notches in its edge is held by two gold washers L and M. held on
opposite sides of the rubber disc.
That end of the device carrying the soft rubber disc H is inserted in the auditory
channel of the ear until the head C is adjoining the delicate organs of the ear. The
magnetized rod receives the impulses of the air wave and .carries them along and
discharges them to the nerve of the ear with slight magnetic force causing the
organs of the ear to take on increased action. The rubber discs H and K hold the
device in place in the car and protect the delicate organs from coming in contact
with the gold parts of the device.
The front gold washer M or disc receives the sound waves and conveys thein to
the magnetic rod. The rubber disc K is held in the outside part of the ear just out
of sight but within reach of the fingers to permit of inserting and withdrawing the
instrument.

page_text: Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
1. An artificial ear drum made substantially as herein shown and described and
consisting of a magnetized steel rod on each end of which a rubber disc is held as
set forth.
2. In an artificial ear drum the combination with the magnetized steel rod A
having a gold or silver covering B of a rubber disc held on each end of the rod
substantially as herein shown and described.
3. In an artificial ear drum the combination with the magnetized steel rod A
having a flat head C of the rubber discs H and K on the end of the rod and the
rubber washer D and the gold washer J on opposite sides of the disc H substantially
as herein shown and described.
4. In an artificial ear drum the combination with the magnetized steel rod A of
the rubber discs H and K on the ends of the same and the gold washers L and M
on opposite sides of the disc K substantially as herein shown and described.
5. In an artificial ear drum the combination with a magnetized steel rod A of
rubber discs held on the ends of the same, which discs have notches in their edges,
substantially as herein shown and described.
6. In an artificial ear drum the combination with a magnetized steel rod of the
rubber discs H and K held on the ends of the rod and provided with notches in
their edges, the disc H being provided with apertures b, substantially as herein
shown and described.
