IMPROVE- MENTS IN ORGANS
Year: 1885

page_text: I, MATTHEW LEE LODGE, of Windrush House, Hall Lane, Bradford in the County
of York, Gentleman, do hereby declare the nature of my invention for IMPROVE-
MENTS IN ORGANS to be as follows:-
The object of this invention is to open the valves admitting air into the notes by
more direct mechanical arrangements than hitherto.
In organs as at present constructed the keys when pressed actuate a series of
levers connected by wires, and thus open the valves which are at a considerable
distance from the key-board: these connections are liable to get out of order.:
My improvement consists in arranging the finger key to form part of the lever
for the opening of the valve: the other end of the finger key is connected by wire
directly over the valve. This arrangement necessitates the bringing of the main
wind trunk to the front, and the connecting of the same to the respective valve
boxes, and from these connections to the notes in the ordinary way.

I, MATTHEW LEE LODGE of Windrush. House, Hall Laue, Bradford, in the County
of York, Gentleman, do hereby declare the nature of my invention for IMPROVE-
MENTS IN ORGANS 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 this invention is to open the valves admitting air into the notes
by more direct mechanical arrangements than hitherto.

page_text: In organs as at present constructed the keys when pressed actuate a series of
levers connected by wires and trackers, and thus open the valves which are at a
considerable distance from the key-board: these connections are liable to get out
of order.
My improvement consists in arranging each finger key to form part of the lever
for the opening of the valve, the opposite end of the key inside the organ being
connected by a wire direct to the valve: or the end of the key may be arranged to
come in contact with a curved light bar by which the valve is opened or closed.
In the accompanying drawings Figure 1 represents a sectional elevation through
a portion of the key board of an organ arranged according to my invention: and
Figure 2 is a section through the connections from the wind chest to the note
pipes.
The end of each finger key A inside the organ may be connected by a wire direct
to the valve B immediately under the same so that when the key is pressed down
at A¹, it will ride on its fulcrum at C and open the valve B, thus allowing the
wind to pass from the main air chest E to the air chest F above the valve B and in
connection with the note pipes.
Or the end of the finger key inside the organ may be prepared with a small
pulley as at G which when the key is pressed down at A', the pulley acts upon the
curved light bar H. which works freely through the air chest casing F and is
raised by the said pulley, the spring J being so arranged that when the curved
bar H is removed from off the valve B, it causes the valve to open independent to
any wind pressure there may be in the main air chest E. On allowing the key
to go into its normal position, the weight of the curved bar H causes the valve to
close and the said bar is kept in contact with the pulley G by means of the
spring K pressing against the same.
The pipes for supplying air to the main notes, are arranged with an horizontal
valve M which is opened by the pressure of air, and in case there in more air
pressure in the air trunks R than is required by the note pipes, the valve M will
be raised higher 'as shewn at P and thereby raise the slide valve N connected
thereto by the cord S, thus allowing any extra pressure of air not required by the
note pipes to escape.
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
The finger keys arranged as levers for the opening of the valves B substantially
in the manner described and as illustrated by the accompanying drawings.
The additional valves B and air trunks F for supplying air to the ordinary note
pipes without the use of trackers.
