Improvements in Apparatus for Facilitating the Playing of the
Organ or like Wind Musical Instruments.
I HUGO BEYER of 16 Master Samuelsgatan, Stockholm in the Kingdom of
Sweden, Singing Master, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to allow the player of an organ or harmonium by
a special mechanical arrangement to push down a key generally in the bass, and to
keep the selected key remaining down and at the same time have the corresponding
tune sounding until another key is pushed, when the first one is released and the
second one is sounding, and so on according to the wishes of the player, who, also,
can release one or all of the keys.
The apparatus consists of a number of bent or cranked parts formed as a kind of
double arined lever with connecting axes, the one end of each of the lever arms
being acted upon by one of a series of pushers or socketed stems bearing on their
outer ends knobs which project from their casing and located so that they may be
easily reached by the player, and at their inner ends each push piece spindle has
affixed thereto two enlargements, spurs or lifters, one of lesser diameter and one of
greater diameter or lift with a groove between them. The outer ends of these push
pieces act each on the upper or outer ends of one cranked arm of the axes, the other
ends of which are hooked and are connected to adjustable wires attached respectively
to projecting bent arms or fingers which swing on centres at their ends opposite to
the key ends and are suitably guided, said arms being adapted to depress one of the
keys of naturals or the sharps, or, of the white or black keys-corresponding to the
stud pushed in by the player at any place of the manual generally in the bass. The
longer arms for the sharps are hinged to be capable of folding sidewise for
transport.
Above the enlargements, spurs or lifters is arranged a flanged plate rocking on
centres and this plate is capable of acting as a catch to the push pieces of the knobs.
When a knob is pushed in the spur is caught by the rocking flanged plate. The
result of this arrangement being that for each knob that is pushed in a corresponding
key is pressed down and remains so until the knob is released.
When another knob is pushed in the lifter of greater height lifts the disc and
releases the knob caught by the lower spur. There is also a loose knob not in
connection with any key but acting to press on a rock arm so as to lift the flanged
plate, when depressed, by which the player can lift that plate and release any other
knob.
This arrangement can either be made in fixed connection with any new organ or
harmonium or in a separate apparatus, when it can easily and in a few minutes be
applied to any ordinary existing organ or harmonium.
For an ordinary existing organ the mechanism may be attached to the key board
by adjustable hooked straps of metal and thumbscrews.

I HUGO BEYER, of 16 Master Samuelsgatau, Stockholm in the Kingdom of
Sweden, Singing Master, do hereby declare the nature of this invention and in
Pas 1171

page_text: in and by the following statement :—
The object of this invention to enable the player of an organ or harmonium to
intensify the sound or harmony of the instrument by allowing him by a special
mechanical arrangement adapted to push down a key-generally a bass key, and
cause the note or tone to sound continuously, until another key is pushed, when the
first one is released and the second continues to sound, and so on according to the
wishes of the player, who also can release any or all of the keys, thus sounding.
Having thus stated the nature of the said invention I proceed to describe the
manner of carrying it into effect and the special arrangements necessary therefor.
This invention can be adapted as well to new organs or harmoniums as also to old
ones, when the mechanism is placed in a separate box, which can easily be fastened
at the front of the instrument by means of screws.
DESCRIPTION OF THE DRAWINGS.
Figures 1 to 10 show various illustrations of apparatus according to the invention
adapted for application to new instruments.
Figure is a plan of the manual and Figures 2 to 6 are various cross sectional
views of parts of the same.
At the middle of the manual are arranged a number of knobs a, (Figure 1), each
connected with a corresponding. key of the manual, by means of a double armed
lever b, c, d, (Figs. 1, 2, 3, 4) resting in the bearings e, with the arm b (Figures 2, 3,)
leaning on the inner end of the spindle f, which carries the knob a, and with the
arm d connected with the key g (Figures 1 and 4) by means of a link h. When the
knob a is pushed in the key g (Figure 6) is consequently also pressed down, and
its note or tone will sound.
are provided with two enlargements or lifters i and k, separated
The spindles
by the groove l.
Above and along the spindles is placed a rocking check plate m. that fits to the
groove. When the knob is pushed the check plate is lifted by the enlarge-
ment i, catches the groove 7 and keeps the spindle f, and the knob a in this inner
position (Figure 3). As long as this continues the corresponding key 9 is also
pushed down, allowing its note or tone to sound.
When another knob is pushed the second lifter k on the spindle of this knob lifts
the check plate so high that the lifter i is left free, releasing the combined spindle,
knob and key.
This second knob is then caught and kept in the inner position by the same
arrangement of the check plate and the groove and so on, the one knob and key after
another.
If I wish to release any knob and key without setting another note or tone
sounding there is a separate knob n (Figures 1 and 4) which only lifts the check
plate m, thus releasing any other checked knob and key.
If I wish to put the check plate m out of action I have a separate part or push o
(Figure 5) by which the check plate is lifted and kept up in a position that prevents
it from catching the groove of any spindle if pushed.
Figures 7, 8, 9 and 10 show. like sectional views of a modified arrangement of the
invention.
In some cases I prefer to make use of a set of common keys instead of knobs, and
then these keys are placed as a separate manual (Figure 7). The double armed
lever b, c, d transfers the motion of the small key a¹ to the playing key 9, (Figure 8),
as before described, and the spindle fis provided with the two lifters i and k. The
check plate m placed at the side of and pressed against the lifters by a spring p.
In order to release any pushed key there is an extra key n' (Figure 9) which
acts on a spindle provided with only one lifter k¹, that puts the check plate out of
action on the lifters i, as long as the key n' is pushed. I have also another key
(Figure 10) acting on a spindle ƒ provided with a lifter o and hook o, that keeps

page_text: the check plate out of action as long as desired, or till the key n¹ (Figure 9) is
pushed, when the lifter o (Figure 10) is released and the connecting spindle and key
are replaced in their common position by means of a spring r.
Figures 11, 12, 13, 14, 15, 16, 17 and 18, show front, edge, sectional and plan
views of an arrangement adapted for use with old or existing instruments.
In order to enable. this invention to be used upon old instruments I place the
mechanism in a separate casing as shown in these figures.
This case is fastened to the front of the instrument by means of screws and arms s
adjustable to suit different forms of instruments.
"
At the side of this case are knobs a, acting on the double armed lever b, c, d, the
spindles connected with the knobs are provided with lifters i and k, above the lifters
is the check-plate m, acting as above described.
organ, or
In order to communicate. motion of the arm d to the key of the
instrument, there are provided a number of arms or fingers t, u (Figure 12, 16,
17, 18) moving round their centres v and made to correspond to the keys of the
instrument and so arranged by means of the movable and adjustable link has to
touch the same. The fingers corresponding to the naturals or white keys are those
marked t touching only the edge of the keys, and permitting the player to push any
key independently of the mechanism.
The fingers u corresponding to the sharps or block keys are made in such a manner
that they can pass in the interspace between two white keys, and project each at
their outer ends in a part w, that only touches the edge of the black key, thus being
out of the way of the player permitting him to play as well on the keys direct or by
means of the knobs and connecting parts.
The fingers u for the block keys can be hinged to be capable of folding sideways,
in order to facilitate easier packing.
The knobs a, the double armed lever b, c, d, the check plate m and all other parts
shown in Figures 12, 13, 14, 15, 16, 17, 18 substantially correspond to the same parts
as described above at Figures 2, 3, 4, 5, 6 and act in the same way.
'
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. An arrangement or combination of parts of apparatus applicable to organs and
harmoniums or other like wind musical instruments, by which a special set of knobs
or keys are placed either above or below the manual, and combined with some of
the ordinary keys of the manual generally in the bass by means of double armed
levers, in such a way, that a player may by pushing any of these knobs or extra
keys simultaneously get the corresponding key pushed down and its note sounding,
substantially as shown and described.
2. An arrangement or combination of parts of apparatus applicable to organs or
harmoniums or like wind musical instruments, by which knobs or extra keys, such
as described, when pushed in are kept in this position by means of a check-plate
that fits into a groove on the spindle connected with the knob or extra key, sub-
stantially as shown and described.
3. An arrangement of means applicable to organs or harmoniums or like wind
musical instruments by which any knob or extra key is released when pushing
another knob or extra key, this being done by a lifter fixed to the spindle carrying
this knob, and which lifts the check plate out of the groove of the other, releasing
the spindle the key and the knob combined therewith, substantially as shown and
described.
4. An arrangement of means applicable to organs, harmoniums or like wind
musical instruments, by which the check plate is lifted or lowered according to the
wishes of the player, so that it may or may not catch the groove on the spindles,
thus permitting a performer to play on the knobs or extra keys as on ordinary keys,
substantially as shown and described.

page_text: 5. An arrangement of means applicable to organs, harmoniums or like wind
musical instruments, consisting of a knob or extra key only in connection with a
single lifter, by means of which any knob that is pushed in can be released, sub-
stantially as shown and described.
6. The combination of the arrangements of. parts, described and claimed in the
foregoing claims, in one instrument or piece of apparatus, substantially as shown and
herein before described.
7. The arrangement of the above described knobs, levers, lifters, check plate,
grooves and other parts in a special box or case in such a manner that it can be
fastened to an existing organ or harmonium or like wind musical instrument and
provided with projecting arms or fingers that correspond to, and when the box is
properly fixed, touch the keys of the instrument, substantially as and for the purpose
shown and described.
