HENRY MARLOW of 90 Godolphin. Road Shepherds Bush in the county of
Middlesex AN IMPROVED APPARATUS TO FACILITATE HEARING AND SPEAKING
SIMULTANEOUSLY
The object of this invention is to construct or arrange an ear bell or trumpet to
a speaking tube mouthpiece in such a manner that a continued conversation can
be carried on by persons at a reasonable distance from each other. The speaking
tube and ear bell as a combined article is applicable to all existing speaking tubes
and is so made that it can be readily affixed and removed at will.
The construction and arrangement of my combined ear trumpet or bell and
speaking mouthpiece and method of attaching the same to any length of tubing is
clearly shown in the annexed drawing. A is the ear bell and B the speaking
mouthpiece connected by the branch C attached to the neck D to form one article
as before mentioned. E is a socket or ferrule for the attachment of a short length
of flexible tube F this having on its other end a tapered ferrule G to enable it to
be slipped into a fitted tube and be temporarilly fixed in position.
If a similar appliance be fitted to the opposite end of the fixed tube an
unbroken conversation can be carried on by two persons at a distance apart with
great facility
The appliance as shown is of a portable character and can be readily affixed into
the whistle hole of an existing fixed speaking tube.
