PROVISIONAL SPECIFICATION.
Combined Ear-trumpet and Artificial Stretched Ear-drum.
I, HENRY LEIGH of 225 Upper Brook Street Manchester, Specialist for
Deafness do hereby declare the nature of this invention to be as follows:-
--
A combination of a miniature ear-trumpet (preferably of gold or silver) and a
stretched artificial ear-drum, the said drum forming also the centre of a sucker
which is used for drawing (by suction) sunken car-drums into their proper
position.
Construction of "Combined ear-trumpet and artificial stretched ear-drum ”.-
Consisting of:-
-
A small tube (preferably of gold or silver) shaped like a post-horn, and of a size
which will permit of it fitting comfortably in the ear; the outer or larger end of
tube being shaped so as to open out trumpet-fashion for the double purpose of
collecting sound & for preventing the instrument being pushed too far into
the car.
A ring of wire to be soldered round the outside edge of larger end of tube to
prevent said edge from scratching the ear, & to enable the instrument to be the
more easily removed from the ear.
Also a ring of wire to be soldered on the outside of smaller end of tube to enlarge
same so as to allow of a piece of thin rubber being stretched & tied over the
opening at small end of tube in such fashion as to form a drum, or stretched surface
on which the sounds will strike after passing through the tube, the smaller end of
which, when in the ear, rests against the natural ear drum in such a way that the
artificial stretched drum also rests against the natural ear drum so that when sounds
passing through the tube cause the artificial drum to vibrate, the vibrations will be
communicated to the natural ear-drum,--any perforations in which will be covered
by said artificial drum, or by a small rim or disc of rubber which surrounds it,
which is put on for the purpose of forming a sucker in order that where the natural
ear-drum is sunken inwards the sucker shall by suction draw it into its position
again.
The sucker is formed by placing a disc of rubber (slightly larger than the
artificial stretched drum) on the smaller end of tube and just behind the stretched
drum in such a way that the stretched drum forms the centre part of the
sucker.
The disc of rubber being placed in this position in the following way :-
Get the disc to about the size of the natural ear-drum and puncture it in the
centre only to such an extent as to be able to just see through the puncture, then
stretch the disc in such a way as to enlarge the hole temporarily, and ease the
small end of tube (covered by stretched drum) through the hole so that the dise
just slips over the ring at end of tube (over which the drum is stretched) and rests
behind the ring, but not behind the silk thread with which the stretched piece of
rubber is tied on which forms the drum.

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:-
A small metal (preferably gold or silver) ear trumpet with a stretched artificial
drum and sucker attached, to fit in the ear, with only the outer end of trumpet
visible.
The construction of this invention is as follows,
A small tube (preferably of gold or silver) shaped like a post horu, and of a
size allowing it to fit in the ear, and being enlarged at the outer end A so as to
open out trumpet fashion for the double purpose of collecting sound and also to
prevent the invention being pushed too far into the ear.
A ring of wire (preferably of gold or silver) to be soldered on the outer edge of
the smaller (& inner) end B of the tube to allow of a piece of thin rubber being
stretched over & tied round the said end of tube so as to form a drum C or stretched
surface susceptible to sound waves which pass through the trumpet, the said drum
being in position against the natural ear-drum when the invention is in the ear, the
vibrations of the artificial drum being therefore communicated to the natural ear
drum.
A disc of thin rubber is placed on the inner end of tube, to form a sucker D by
passing the said end (over which the drum is tied) through a minute hole in centre
of said disc; This is done by stretching the disc so as to temporaril enlarge the
hole to allow the end of tube to be passed through. The disc or sucl then rests
securely between the silk which is tied round to fasten the "drum," at the ring of
wire at end of tube (which ring is, however, covered by the rubber which is tied
over to form the "drum").
The stretched artificial drum therefore forms the centre of the sucker, which
being of the size of the natural ear drum, covers any perforations in the drum of
the ear & so remedies such defects; or will, by suction restore the natural ear
drum to its proper position should the drum of the ear be sunken inwards towards
the head, yet at the same time not obstructing the passage of sound while the
suction of the invention is restoring the natural drum to its right position.
A ring of wire (preferably of gold or silver) is also soldered over the edge of the
larger, or outer, end A of trumpet to prevent the invention scratching the ear &
also to facilitate the removal of the trumpet from the ear.
Having now particularly described and ascertained the nature of my said
invention & in what manner the same is to be performed I declare that what
I claim is
1. A combination of an ear trumpet & stretched artificial drum.
2. A small ear-trumpet with sucker to adhere to drum of the ear.
3. Sucker attachment having stretched drum in centre to make it susceptible to
sound waves.
4. The invention being so constructed that no metal or hard substance comes in
contact with the drum of the ear.
