PROVISIONAL SPECIFICATION.
Improved Electro-pneumatic Action for Organs.
I ARTHUR PRICE Organ Builder 162 Market Street Birkenhead Cheshire do
bereby declare the nature of this invention to be as follows :-
That is to say, my said invention, comprises improvements in electric pneumatic
action for organs, by means of which, the organist is enabled to control the speech
of the various pipes, irrespective of his distance from the instrument, by electric
control or pneumatic tube.
In my improved apparatus, the wind pressure is unlimited the electric contact
is effected by devices arranged within the keyboard, or console, and operating
by means of electric current derived from battery or other source of electricity.
My invention also comprises an improved valve seat, also electric armature and
valves combined, and pneumatic control.
And in order that my said invention and the manner of performing the same
may be properly understood, I herewith append "1" sheet of drawing to be herein-
after referred to, showing my improvements.
Figure "1" of drawing is a transverse vertical section of action.
Figure 2. is a vertical longitudinal section of action.
A 1. is plan of valve seat, and C 1 is electric magnet of which one is shown in
Figure 1. and which convert the electrically transmitted impulses into pneumatic
action.
In this drawing the same reference letters and numerals, are used to mark the
same or like parts wherever they are repeated.
In the example of my improved apparatus shown in drawing, this action may be
used either in pallet box, namely, wind chest of soundboard, as shown in Figure 1
or detached outside of sound board.
Electric current is conveyed from battery to the keyboard in the console. When
the key is depressed, it makes a contact and the electric current from each key is
conveyed to a terminal board, and passes thence by the wire G 1 to electric
magnet C. and a branch return wire K 1. connecting magnet C 1. to the
battery.
On depressing key the magnet C 1. becomes magnetized, it attracts the
armature M 1., closes the exhaust valve N 1. and opens valve O 1. allows the wind
inside of motor B 1. causing the wind pressure to be equalized inside and outside, of
motor B 1; motor B 1. then allows exhaust valve E 1. to open and closing
valve D 1. motor F 1. collapses, pulls the pallet G 1. open, and supplies the
wind to the various pipes on the sound board.
On breaking contact at the keyboard, the magnet becomes unmagnetized, and allows
the armature M 1. to drop, opening valve N 1. and closing valve O1. Motor B 1.
then falls and closes the exhaust valve E 1. opens valve D 1. and allows equalized
wind pressure on motor F 1. the spring H 1. closes pallet G 1. pulling motor F 1.
ready for a repetition of action.
Having now particularly described and ascertained the nature of my said
invention, and the manner of performing the same, I declare that what I
claim is;
1. In an organ; the improved arrangement and combination of electrical
transmission device, as shown the accompanying drawing at letter A 1. Fig. 1.

page_text: 2. In an organ, with electrical or pneumatic transmission apparatus, the
oscillating motor B 1 for controlling motor F 1. for closing and opening pallets
for pipes.

I, ARTHUR PRICE Organ Builder 162 Market Street Birkenhead Cheshire, 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 :-
That is to say, my said invention comprises improvements in electric pneumatic
action for organs, by means of which, the organist is enabled to control the speech
of the various pipes, irrespective of his distance from the instrument, by electric
control or pneumatic tube.
In my improved apparatus, the wind pressure is unlimited, the electric contact is
effected by devices arranged within the keyboard, or console, and operating by
means of electric current derived from battery, or other source of electricity.
My invention also comprises an improved valve-seat, also electric armature
and valves combined and pneumatic control.
And in order that my said invention, and the manner of performing the same may
be properly understood, reference is made to the sheet of drawing, left with the
Provisional Specification.
Fig. 1. of drawing is a transverse vertical section of action.
Fig. 2., is a vertical longitudinal section of action.
A 1. is plan of valve-seat and C 1. is electric magnet, of which one is shown
in Fig. 1.; and which converts the electrically transmitted impulses into pneumatic
action.
In this drawing, the same reference letters and numerals are used to mark the
same or like parts, wherever they are repeated.
In the example of my improved apparatus shown in drawing, this action may be
used either in pallet box, namely, wind-chest of soundboard, as shown in Fig. 1. or
detached outside of soundboard.
Electric current is conveyed from battery to the keyboard in the console.
When
the key is depressed, it makes a contart, and the electric current from each key is
conveyed to a terminal board, and passes thence by the wire G 1. to the battery.
On depressing the key, the magnet C 1. becomes magnetized, it attracts the
armature M 1. closes the exhaust valve N 1. and opens valve O 1. allows the wind
to enter the motor B 1., causing the wind pressure to be equalized inside and
outside of motor B 1. Motor B1. then allows exhaust valve E 1. to open, and
closing valve D1. motor F 1. collapses, pulls the pallet G 1. open and supplies the
wind to the various pipes on the soundboard.
On breaking contact at the keyboard, the magnet C 1. becomes unmagnetized
and allows the armature M 1. to drop, opening valve N 1. and closing valve 01.
Motor B 1. then falls and closes the exhaust valve E 1. opens valve D 1. and allows
equalized wind-pressure to motor F 1., the spring H 1. closes pallet G 1. pulling
motor F 1. ready for a repetition of action.
Having now particularly described and ascertained the nature of my said
invention, and the manner of performing the same, I declare, that what I
claim is
(1.) In an organ, the improved arrangement and combination of electrical

page_text: transmission device, as shown in the accompanying drawing at letter A 1. Fig. 1.
(2.) In an organ with electrical or pneumatic transmission apparatus, the
oscillating motor B 1. for controlling motor F 1. for closing and opening pallets for
pipes.
