PROVISIONAL SPECIFICATION.
An Improved Method of Lighting Pianofortes by Electricity.
.
KENNETH BARRY RYAN Littlestone-on-Sea Kent, Student of Electricity, do
hereby declare the nature of this invention to be as follows:-
An accumulator is placed in the lower part of the piano in such a way that it
will not interfere with the strings. From it wires are led up the sides to the
sconces, with switches intervened for turning the light on or off. The wires are
connected to the accumulator and the sconces by means of Plugs and Sockets, so
that the removal of any part of the Piano is very easily effected without the
unwiring, of any of the electrical connections.

I, KENNETH BARRY RYAN Littlestone-on-Sea, Kent, Student of Electricity, 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:-
An accumulator is placed in the lower part of the piano in such a way that it
will not interfere with the strings. From it wires are led up the sides to the
sconces with switches intervened for turning the light on or off. The wires are
connected to the accumulator and the sconces by means of plugs and sockets so
that the removal of any part of the piano is very easily effected without the
unwiring of any of the electrical connections.
For purposes of illustration, I will now refer to the annexed drawings, in
which:-
Figure 1. is a front elevation of my invention.
Figure 2. sectional plan of same to enlarged scale shewing the socket joint or
connection.
a is an accumulator or source of electricity and which is connected to the
lamps 6 through the medium of the wire c. When it is required to remove the
front panel d this can be readily done as the projection e will leave the socket
piece f when the panel is removed, the socket piece and projection being con-
nected respectively to the circuit wires. By this arrangement the desired portion
of the piano may be removed without necessitating the breaking of the socket
wires as wherever they pass through two movable parts instead of being continuous

page_text: a socket and projection piece is interposed, thus enabling the part to be separated and
replaced as desired without necessitating the cutting or breaking of the circuit
wires. g are switches for the purpose of turning the current on or off from the
lamps b, so that either lamp may be used separately or both together as required
by operating the switches g. The dotted lines indicating the course of the current.
It will be understood that although for purposes of illustration I have shewn
an arrangement for carrying out the object of my invention, I do not confine
myself to the particular way shewn, as there are various modifications of the
arrangement which might be carried out without departing from my invention.
The dotted lines in Figure 2 represent where the socket f is cut or slotted so as
to give the walls of same a certain amount of elasticity.
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 combined construction and arrangement of the various parts substantially
as described and illustrated herein.
2. In means for lighting pianos with electricity; a socket and spigot forming
terminals and so arranged that the parts upon which the socket and spigot are
carried may be disconnected without interfering with the wires forming the
circuit; suitable switches being provided for the purpose of lighting or
extinguishing the lamps.
