page_text: M goes to magnet for taking stop in. M¹ goes to magnet for pushing stop out.
L is a spring formed by two metal pieces to rub on sides of contact pieces J and J¹.
The said spring L is connected to wire O, and fastened to lever E; and grips the
metal pieces and J', so as to make a rubbing contact thereon at the points.
sufficiently firm to hold the lever E in position after it has been set for reversing
the contact from J or J¹, or vice versa.
In Fig. 2, R is the wind-chest. S the pneumatic bellows with valve T for
channel U.
The electro-magnet N and armature N' are of the construction shown and
described in the Specification of my Patent No. 9409 dated May 18th 1892. V is
the channel to the pneumatic bellows S. In Fig. 3, the wires O upon the frame P
are arranged or splayed out so that when the pedal W is depressed by the foot, the
end W of the pedal passes between the ends X X of the wires O, the said ends X X
gripping or sliding on the end of the pedal W and establishing the electric circuit.
The number of the wires O is regulated by the number of the stop actions as
shown in Fig. 1, and there may be any number of these stop actions. Y is a
recoil spring for breaking the circuit when the foot is taken from the pedal W.
The action is as follows:-
Draw out the desired combination of stops A. Then draw out the stop called
interchangable combination No. 1 which is connected to the trundle H which will
bring the lever-rail and levers E against the block D causing For F¹ to reverse
the contact from J to J' or vice versa, thus setting the desired combination.
Then push in stop called interchangeable combination No. 1 which will move the
lever-rail and levers clear of blocks D so that the draw stops A can be moved in
or out without disturbing the set combination. On depressing the foot pedal W
the end W' is brought between the ends X X of the springs so completing the
electric circuit, and causing the electro-magnet N to attract the armature N' which
stops the passage of wind through the electro-magnet N into the channel V to the
pneumatic bellows S, the bellows S then collapse, and lower the valves T and T,
the valve T¹ closing its aperture, and the valve T opening its aperture to allow the
wind to pass from the wind chest into the channel U and through the pipes T' to
the bellows C.
On taking the foot of the pedal the spring Y causes the pedal to assume its
normal position so breaking the electric circuit by withdrawing the end W₁ of the
pedal from the ends X X. At the same time the armature N¹ falls away from the
electro-magnet N, and compressed air passes through such and the channel V into
the bellows S inflating such and causing the valve T to close its aperture, and the
valve T to open its aperture..
The electric circuit shown in Fig. 1, is changed when the trundle is operated to
withdraw the spring L from the top plate J to J'.
Figs. 5 and 6. In these figs. the piston A¹ is used instead of the pedal
arrangement before described, for completing and breaking the circuit as required.
The piston is carried through the frame A2 and engages into a block A having
an end A* provided with a contact piece A³ for engaging with the ends X X of the
wires as before described.
The block A³ has notches A into which engage the free ends of blade or other
such springs A' the said springs at their other ends being secured to the frame A³,
or spiral springs or the equivalent may be used.
The action is as follows:-
On the piston A¹ being pushed in by hand the contact piece A' is caused to
engage with the ends X X of the wires O so completing the circuit.
On releasing the piston the springs A' return the piston to its normal position so
withdrawing the contact piece A' from the ends X X of the wires O, and so
breaking the circuit. The action of the other parts is the same as in Figs. 1, 2, 3
and 4.

In Fig. 9. W is a foot pedal connected by wire W to the pallet W2 in wind
chest W3 W is a passage or channel leading to the pipe or tube W. Y is the
recoil spring.
The action is as follows:-
Draw out the desired combination of stops A. Then draw out the stop called
interchangable combination No. 1 which is connected to the trundle H which will bring
the lever-rail and levers E against the block D causing For F' to reverse the contact
from J to J or vice versa, thus setting the desired combination. Then push in stop
called interchangable combination No. 1 which will move the lever-rail and levers
clear of blocks D so that the draw stops A can be moved in or out without
disturbing the set combination. On depressing the foot pedal W, the pallet W2 is
lifted by the wire W admitting compressed air from the wind chest W³ into the
passage or channel W, the compressed air passes by the pipe W' to the pipe G³,
see Fig. 7, which admits air into the valve-chest G³, opening one of the channels
and closing the other by means of the valve G².
In the drawing G' is shown open, and G* shut.
The levers E and G are arranged to work or slide freely on the wires G¹ and G',
when the trundle is operated so as to cause the lever E to clear the blocks D upon
the draw stop A by which means the draw stops are free to be drawn in or out at
will. The wire G is also arranged to raise the lever E to its horizontal position
when the valve G2 is raised. The bellows are fed from the pipes T2, see Fig. 8,
regulated by the valves, the action of which will be readily understood from the
description under Figs. 1, 2, 3, and 4.
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 :-
1. In organs, producing an interchangeable combination of stops, substantially
as set-forth.
2. In organs, the combination of parts by which the stops can be electrically
interchanged at will, substantially as set-forth.
3. In organs, the combination of parts by which the stops can be pneumatically
interchanged at will, substantially as set-forth.
