PROVISIONAL SPECIFICATION.
Improved Tubular Pneumatic Actions for Organs.
ALFRED MONK Organ Builder 550 Holloway Road London N. do hereby declare
the nature of this invention to be as follows:-
Improvement in the construction of organ valves in order to obtain greater
velocity and to be easier to open.
These valves are constructed with a cover over the same which prevents the wind
in the sound-board pressing on Valve and resisting the opening of the same.
This valve is made in 2 forms one to open parallel, and the other to open at
one end only.
These valves are worked by Pneumatic Power.
1 claim the invention of covering the Pneumatic Valves to protect from wind
pressure on valves when required to open.

COMPLETE SPECIFICATION.
Improved Tubular Pneumatic Actions for Organs.
ALFRED MONK Organ Builder 550 Holloway Road London 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 :-
Improved construction of valves and action for organs in order to obtain greater
velocity and to be easier to open. These valves are constructed with a cover F over
the opening part A which prevents the wind in the sound board from pressing on the
valve A and resisting the opening of the same.
The valves are made in forms one A to open at one end only and one B to open
parallel.
The valves are worked by compressed air in a tube leading from a motor D near
the organ keys to valves at the sound board.
Fig. 1 represents covered valves in 2 forms one valve marked A opens at one end
only and the other valve B opens parallel.
These valves are operated by the air being exhausted from the inside of these valves
which allows the air surrounding the valves to force in the sides of valves sufficient
to draw the valve off its seat to open.
Fig. 2 shows a motor marked C which opens a pallet K which lets the air into or
out of valves A and B.
The motor C is worked by the air being drawn out by raising motor D by the
organ key.
Fig. 3 shows the main motor which is raised by the organ key H.
The motor D when raised receives the charge of air which is drawn through the
tube G by motor C.
On lowering motor D the air is driven back to motor C and at the same time
opening the pallet J to admit an extra charge of air from wind chamber I which raises
motor C.
Fig. 4 shows a motor to open a pallet for the hass notes of which the middle part
marked E is worked by the air from the sound board.
The tube leading from fig. 2 to fig. 3 is kept charged with compressed air which is
shifted backwards and forwards from motor D to C.

page_text: 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
.
The invention of constructing valves which the working parts are covered and
protected from the wind pressure resisting the opening of the valves..
Also the working of the motor by shifting backwards and forwards of compressed
air in the tubes G by raising and lowering motor D by organ key H.
Also the means of sustaining the charge of compressed air in tube and the pallet J
which admits the charge.
Also the construction of motor for the bass notes.
