Improvements in Telephone Receivers and the like.
I, GUILLAUME ARNAUD NUSSBAUM, of 29, Ludgate Hill, E.C., in the County of
Middlesex, Civil Engineer, do hereby declare the nature of this invention to be
as follows:-
The object of my invention is to improve the telephone receivers used for the
reception of theatrical, musical, and other auditions, and the like.
My invention consists of a handle made of aluminium, or other suitable
material, at one end of which is fixed a flat piece of steel, or the like, bent in the
shape of a prong or fork or other suitable form. At each end of this prong or
fork is attached the telephone receiver in any suitable manner, but preferably
by means of a ball joint, consisting of a socket attached to the receiver casing,
in which a ball having an external projection is loosely pivoted. The end of the
prong or fork is attached to the external projection of the ball, by a screw or
other means. Between the end of the prong or fork and the socket is placed
a bent spring, which holds the receiver in position, but allows it to adjust itself
to the ear.
The prong or fork stretching according to requirements and acting as a spring,
holds the receivers firmly to the ears without being pressed.
The connecting cord is brought through the inside of the handle, and attached
to the receivers in the usual manner.
COMPLETE SPECIFICATION.
Improvements in Telephone Receivers and the like,
I, GUILLAUME ARNAUD NUSSBAUM, Civil Engineer, of 29, Ludgate Hill, Lon-
don, E.C., in the County of Middlesex, do hereby declare the nature of this in-
vention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The object of my invention is to improve the telephone receivers used for the
reception of theatrical, musical and other auditions, and the like.
My invention consists of a hollow handle A Fig. 1 made of aluminium or
other suitable material, at one end of which is fixed a flat piece of steel B or

page_text: the like, bent in the shape of a prong or fork, or other suitable form, at each
end of this prong or fork is attached a telephone receiver C in any suitable
manner but preferably by means of a ball joint, Fig. 2 consisting of a socket D
attached to the receiver casing, in which a ball, E having an external projec-
tion F is loosely pivoted. The end of the prong or fork B is attached to the
external projection F by a screw G or other means. Between the end of the
prong or fork, and the socket is placed a bent spring, H which holds the receiver
in position but allows it to adjust itself to the ear.
The prong or fork stretching according to requirements, and acting as a
spring holds the receivers firmly to the ears, without undue pressure. Instead
of using a plain spring prong or fork to hold the receivers to the ears, the prong
or fork may be combined with a regulating screw & nut, fitted in the handle
in such manner as to allow the adjustment of the receivers to the ears.
The connecting cord I is brought through the inside of the handle A and
attached to the receivers C in the usual manner.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is: :―
1. The combination of one or two receivers in conjunction with a hollow
handle & spring prong or fork in any suitable form, and ball joint & the like,
as hereinto before described.
