PROVISIONAL SPECIFICATION.
Improvements in Telephonic Receivers.
1
I, JAMES PHILIP ANNETT, of the "Elms," Eastleigh, near Southampton, in the
County of Hampshire, Signal Superintendent, do hereby declare the nature of this
invention to be as follows:-
My invention refers to improvements in receivers of telephones, and consists in
arrangements whereby the external noises which interfere with the persons
receiving the message, clearly hearing the words as they come from the telephone,
may be obviated or reduced."
It is a common experience that during the reception of a message noises of
persons talking, or in the case of railways, trains passing; or in houses, vehicles
passing, disturb the hearing of the message.
The object of my invention is to provide means to obviate this disturbance.
In the place of an ordinary receiver I apply an enlarged cup or orifice of suitable
shape made of wood, vulcanite, or other material having the edge of such cup or
enlargement, fitted with a suitable rubber or other flexible lip or rim so that
when the instrument is placed to the receiver's ear external sounds are largely
excluded.
The enlarged cup may be used without the flexible lip or rim if desired.

COMPLETE SPECIFICATION.
Improvements in Telephonic Receivers.
I, JAMES PHILIP ANNETT, of the "Elms," Eastleigh, near Southampton, in
the County of Hampshire, Signal Superintendent, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particularly
described and ascertained and in by the following statement:-
My invention refers to improvements in receivers of telephones, and consists in
arrangements whereby the external noises which interfere with the persons receiving
the message clearly hearing the words as they come from the telephone, may be
obviated or reduced.
It is a common experience that during the reception of a message noises of
persons talking, or in the case of railways, trains paasing, or in houses, vehicles
passing, disturb the hearing of the message.
The object of my invention is to provide means to obviate this disturbance.
In the place of an ordinary receiver I apply an enlarged cup or orifice of suitable
shape made of wood, vulcanite, or other material, having the edge of such cup or
enlargement fitted with a suitable rubber or other flexible lip or rim, so that
when the instument is placed to the receiver's ear external sounds are largely
excluded.
The enlarged cup may be used without the flexible lip or rim if desired.
In order that my said invention may be better understood and more readily
carried into effect I will proceed to describe the drawing hereunto annexed. The
same letters refer to the same parts or substitutes therefor in the two figures of the
drawing.

page_text: Figure 1 represents a sectional elevation of one form of receiver, and Figure 2
a sectional elevation of an alternative form.
In these figures a is the stem which screws on to the tubing now employed, bis
the enlarged cup, and c is the indiarubber rim or lip.
It is obvious that any form of fixing may be made between the tube and the
cup. My invention consists in the enlarged cup provided with an indiarubber rim
or lip.
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 :-
An improved telephone receiver or cup sufficiently large to enclose the ear and
provided with an indiarubber rim or lip, all substantially as described with reference
to the figures of the drawing annexed.

Agent for the said Applicant.
