PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Enabling the Deaf to Hear.
I, BERTRAM THORNTON, of 14 Cecil Squate, Margato in the County of Kont,
do hereby declare the nature of this invention to be as follows:-
The apparatus forming the subject of this invention consists of a telephonic
transmitter and receiver with the usual battery.
Both the transmitter and receiver are provided with handles so that they may be
readily held to the mouth and ear respectively.
Pivotted to the end of the handle of the transmitter are four or other number of
aims which can either lie out of the way in slots in the handle or be turned out at
right angles to the handle so as to form a foot on which it stands. The arms are
held in either position by a collar sliding on the handle.
Ou the handle of the receiver is a spring contact maker adapted to be grasped by
the hand so that the circuit through the battery is broken immediately the instrument
18 laid down. The receiver is connected to its handle by a bayonet or other
suitable joint so that it can be readily detached and it is provided with a
socket or fastening to receive a spring clip or band by which it can be fixed to
the head.
This band is provided with a lug fitting into the same socket on the receiver as
the handle and it also is provided with an automatic spring switch which closes the
circuit when the instrument is placed on the head.
Dated this 5th day of October 1895.

Improvements in Apparatus for Enabling the Deaf to Hear.
I, BERTRAM THORNTON, late of 14 Cecil Square, now of Berkeley Lodge,
Trinity Square, Margate, in the County of Kent, do hereby declare the nature of
this invention and in what manner the same is to be performed to be particularly

The apparatus forming the subject of this invention is shown in the annexed
drawing and consists of a telephonic transmitter a and receiver b with the usual
battery.
Both the transmitter and receiver are provided with handles a' and b' respectively
BO that they may be readily held to the mouth and ear.
Pivotted to the end of the handle of the transmitter are four or other number of
arms o which can either lie out of the way in slots in the handle or be turned out
as shown at right angles to the handle so as to form a foot on which it stands.
The aims are held in position by a collar c¹ sliding on the handle.
On the handle of the receiver b 18 a spring contact maker consisting of a
spring & connected to one pole of the battery and a contact connected to the
other, the arrangement being such that when grasped by the hand the circuit
through the battery is closed whilst it is broken immediately the instrument is laid
down. The receiver is connected to its baudle by a bayonet or other suitable
