A New System of Interchangeable Composition Action in Organs to
Change and Adjust any Desired Combination of Stops.
We CHARLES FREDERICK BRINDLEY, and ALBERT HEALEY FOSTER, Columbia
Place, Suffolk Road, Sheffield, County of York, Organ Builders, do hereby declare the
nature of our invention to be as follows:-
The object of this invention is to enable the organist to bring any desired combina-
tion of stops on any particular piston or pedal, without occupying extra room in the
console, and we accomplish this by means of a pneumatic combination of valves,
bellows, and their auxiliary parts, with great rapidity and certainty.
The organist makes the desired combination by drawing out the stops, and then by
means of a small lock knob conveniently placed, that particular combination is locked
in connection with a corresponding piston, or with a pedal, as long as the lock knob
before mentioned is drawn.
In carrying out our invention we place a compressed-air chamber immediately
behind the drawstop jamb, containing for each drawstop and connected thereto, two
separate oblong bellows placed vertically, and having fixed between them an enclosed
double acting valve, actuated by and communicating with the said bellows. The top or
expanding end of each bellows is attached to the bar of the drawstop, and they are so
arranged that as one expands the other contracts and vice versa, this action being
caused by the admission of air into one bellows, and exhausting the other, and thus
the drawstop is moved in or out as the case may be.
The bellows are filled or exhausted by means of double-acting valves, controlled by
two circular bellows (1) to which they are connected.
When one of the circular bellows (1) is inflated with air admitted through air
tubes by apparatus hereafter described it raises the valve in connection with it,
opening the exhaust to the corresponding oblong bellows which is immediately closed
by the pressure of wind in the surrounding chamber; this action of the bellows opens
the double-acting valve previously mentioned as being fixed between the oblong
bellows and exhausts the other circular bellows (1) causing its valve to drop and
admit air from the chamber into the other oblong bellows ; all these movements
are simultaneous.
We construct the locking mechanism as follows: we form a chamber to which
compressed air may be admitted through a valve operated by one of the sinall locking
knobs before mentioned; this chamber communicates through openings facing each
other with two circular bellows (2) which actuate two valves in connection with
another air chamber, and also with the air tubes leading to the circular bellows (1).
The openings which face each other are made large, and may be closed and opened
alternately by a valve working between them and which we call the locking valve;
upon the same valve pin in a space outside the chamber, we fix exhaust valves to
exhaust each bellows (2), alternately.
These exhaust valves and the locking valve may be worked in either direction by
two small bellows (3) attached to the ends of the valve pin, and communicating by
air tubes with the oblong bellows and draw stops. Thus when the drawstop is pulled
out, one of the bellows (3) is inflated and pushes the locking valve over to the
opposite side; when the drawstop is pushed in the opposite bellows is inflated and
moves the locking valve over, in the contrary direction.
When however compressed air is admitted (by pulling out the locking knob) into
the locking valve chamber, the pressure upon the larger surface of the locking valve
renders it superior to the bellows (3) and therefore prevents any alteration in the
bellows (2) or their valves, until such superior pressure is removed by pushing in the
small locking knob, which opens the exhaust.

The air chamber before mentioned as being connected by means of air tubes to the
circular-bellows (1) and the valves controlled by bellows (2) is supplied with air by
valve opened by touching the corresponding piston; the air so admitted
passes through one or other of the tubes to the circular bellows (1) thereby exhausting
one of the oblong bellows and throwing drawstop either on or off, as it was adjusted
when the locking knob was drawn out.

COMPLETE SPECIFICATION.
A New System of Interchangeable Composition Action in Organs to
Change and Adjust any Desired Combination of Stops.
We CHARLES FREDERICK BRINDLEY, and ALBERT HEALEY FOSTER, Columbia
Place, Suffolk Road, Sheffield, County of York, Organ Builders, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
This invention has for its object, to enable the organist to bring any desired
combination of stops on any particular piston or pedal without occupying extra
room in the console, and we accomplish this by means of a pneumatic combination
of valves, bellows, and their auxiliary parts, acting with great rapidity and
certainty.
The organist makes the desired combination by drawing out certain stops, and
then by means of a small lock knob that particular combination is locked in com-
bination or connection with a corresponding piston or with a pedal, as long as the
lock knob before mentioned is drawn.
In carrying out our invention in the manner shown in the drawings in which,
Fig. 1, is a sectional view of the pneumatic "composition constructed according
to our invention.

Fig. 3, the locking knob.
Fig. 4, the piston.
We place a compressed air chamber D, Fig. 1 immediately behind the drawstop
jamb E, containing for each drawstop, and connected thereto, two separate oblong
bellows F, placed vertically, and having fixed between them an enclosed doubleacting
valve G, actuated by, and communicating with the said bellows F; in the drawing
we have shown a spring H, as the acting medium.
•
The top or expanding end of each bellows is attached to the bar of the drawstop A,
and they are so arranged that as one expands the other contracts, and vice versa, this
action being caused by the admission of air into one bellows and exhausting the
other, and thus the drawstop is moved in or out as the case may be.
These bellows are filled or exhausted by means of double-acting valves I, and
controlled by two circular bellows J, to which they are connected.
When one of the circular bellows J, is inflated with air admitted through air tubes
by apparatus hereafter described, it raises the valve in connection with it opening the
exhaust to the corresponding oblong bellows which is immediately closed by the
pressure of wind in the surrounding chamber D; this action of the bellows opens
the double-acting valve G, fixed between the oblong bellows F, and exhausts the
other circular bellows J, causing its valve I to drop and admit air from the chamber D,
into the other oblong bellows; all these movements being simultaneous.
We construct the locking mechanism shown in Fig. 2, as follows: we form a
chamber K, to which compressed air may be admitted through a valve (not shown)
operated by one of the small locking knobs B, which are fixed in
any
convenient
position; this chamber K communicates through openings L facing each other; with

page_text: two circular bellows M, which actuate two valves N, in connection with another air
chamber O, and also with the air tubes or channels P, leading through the valves Q
to the circular bellows J. The openings L which face each other are made large, and
may be opened and closed alternately by a valve R, working between them in a
horizontal position, and which we call the locking valve, it is fixed in the horizontal
position so as not to be affected by gravitation. Upon the same valve pin or spindle
in a space outside the chamber, we fix exhaust valves S, to exhaust each bellows M
alternately.
These exhaust valves S, and the locking valve may be worked in either direction by
two small bellows T, attached to the ends of the valve pin, and communicating by air
tubes with the oblong bellows F, and drawstops A.
Thus when the drawstop is pulled out one of the bellows T is inflated and pushes
the locking valve over to the opposite side; when the downstop is pushed in, the
opposite bellows is inflated and moves the locking valve over in the contrary
direction.
When compressed air is admitted by pulling out the locking knob B, into the
locking-valve chamber K, the pressure upon the larger surface of the locking
valve R, renders it superior in power to the bellows T, and therefore prevents any
alteration in the bellows M, or their valves N, until such superior pressure is removed
by pushing in the small locking knob which opens the exhaust.
The air chamber before mentioned as being connected by means of air tubes to the
circular bellows J, and the valves controlled by bellows M, is supplied with air by
means of a valve, not shown, opened by touching a corresponding piston C, Fig. 4;
the air so admitted passes through one or other of the tubes P, P₁, to the circular
bellows J, thereby exhausting one of the oblong bellows F, and throwing the
drawstop A either on or off as it was adjusted when the locking knob B was
drawn out.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is or may be performed, we declare that what
we claim is :-

1. An interchangeable or adjustable "composition" for organs_consisting of the
arrangement and combination of the valves and bellows, substantially as hereinbefore
