I, LEOPOLD WAOKS of 16 Darville Road, Stoke Newington, N.,
do hereby declare the nature of this invention to be as follows:-
Warehouseman,
This invention is designed to protect the ear from sounds when silence or less noise
is desired, as, for instance in the case of persons of excitable temperament requiring
perfect quiet at night who may be temporarily residing in a busy Town, or near a
Railway Station.
It consists of a small pad or packet of some light substance such as cotton-wool or
cork sawdust, or other suitable material arranged in a small case of india-rubber or
silk or other covering so as to exclude sound when placed in or over the ear.
To hold it in place if found necessary a small india-rubber ring or clip may be
employed which may encircle or grip the exterior shell of the ear.

page_text: I, LEOPOLD WACKS of 16 Darville Road, Stoke Newington, in the County of
Middlesex, Warehouseman 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 is designed to protect the ear from sounds when noise is objectionable,
as for instance when invalids, or persons susceptible to nervous disorders, or of excitable
temperament require perfect quietness; or in the case of others who may be residing
temporarily in a large Town, or near a Railway Station, and may be unable to sleep on
account of the unusual sounds prevailing in the locality.
It consists of a small pad or contrivance, oval in section and tapering slightly in
form, so as to fit comfortably inside the orifice of the ear, or to rest partly within and
partly without the said orifice.
By preference I employ a body of cork, coated with or surrounded by an envelope
of india-rubber, or other suitable covering, but any other substance which is light, non-
conducting and soft to the touch, such for example as papier-mâche might be
employed, and the coating could be silk or wool if preferred. The exterior might be
faced with silver or gold, or plated therewith, or with nickel for appearance sake if
preferred.
The aforesaid body is hollowed at each end and in the cavity on the inner end, that
is to say the end which is placed inside the ear, a small glass bulb or insulator is
inserted. This bulb is closed at one end and open at the other and is so fixed that the
round closed end is directed towards the drum of the ear, while the open end is
facing the opposite direction. This insulator acts as a refractor of external sound,
receiving and rejecting it, so to say, and preventing it from passing inwards.
In the exterior cavity of the body, is placed a small disc of finely woven wire, or
perforated metal resembling a minute ventilator, and the cavity it covers may be filled
if preferred with some fine soft fibrous substance, or may be left empty when the
packing is not found to be necessary. The object of this perforated disc is to divide
the waves of sound, and thus lessen the force of their concussion within the cavity.
In the accompanying drawings Fig. 1, is an exterior view, enlarged, of my
apparatus.
Fig. 2, is an enlarged longitudinal section of the same.
Fig. 3, is a view of the larger or outer end also enlarged, and shewing the
perforated disc.
A, is the body of cork.

page_text: The mode of using my sound-excluder or antiphone, is simply to insert one of these
contrivances in each ear, when it will be found that violent or shrill noises are so
lessened or softened that they convey little or no shock to the most. sensitive
organization.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is;
1. An automatic apparatus of suitable material for insertion in the orifice of the
car for the purpose of diminishing or excluding sound, as herein described and set
forth.
2. An antiphone or sound excluder for the ear consisting of a hollowed body with
two chambers in one of which is a glass insulator, and in the other. a perforated disc,
as herein explained and set forth.
Dated this 12th day of April 1888.
