Improvements in Musical Instruments.
I, JAMES MORGAN of 223 Ninth Street in the City of Brooklyn and State of
New York, United States of America, Manufacturer, 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 :-

view.
Figure 7 is an isometrical perspective view of one of a series of valves for
controlling the sound producing devices, said valves being represented as having
component parts separated for the purpose of illustrating their construction.
this view parts comprised in additional valves are indicated by dotted lines.
In
Figure 8 is a sectional plan taken upon a reduced scale as indicated by dotted
lines to-w, Figure 2.
Figure 9 is a view taken parallel with the front of the instrument and illustrating
mechanism for winding a music sheet.
Figure 10 is a vertical section parallel with the front of the instrument, of a
tracker board over which a perforated music sheet is intended to travel.
Figure 11 is a top view of this tracker board.
Figure 12 is a horizontal section taken at the plane of the dotted lines w―w,
Figure 10.
Similar letters of reference designate corresponding parts in all the figures.
A, A, A, A designate sound producing devices. In the present example of
my improvement these sound producing devices consist of reeds and there are four
banks of these reeds.
The reeds are arranged in cells B¹ B² B* B₁ which may be of ordinary form and
controlled by mutes C¹C C³ C. These mutes may be operated separately by
ordinary stop rods C to bring into use any one or more of the banks of reeds, or
they may be all operated by one contrivance, as, for instance, by a stop rod C.
As I do not claim anything in the mechanism whereby the different stops are
enabled to control the mutes separately, I shall not further describe such
mechanism.
Preferably the device which is employed to operate all the mutes and which in
the present instance consists of the stop C, will be so combined with the mutes
as to operate them successively instead of operating them all together. The
mechanism for accomplishing this I will now describe, premising that it is best
illustrated in Figures 1, 2 and 3. To the rear end of the stop rod C is pivotally
connected a rod C which is also connected with an arm c that extends radially..

page_text: from a rock shaft C. Affixed to this rock shaft are two sets of cams C³, each set
being of a number corresponding to the number of mutes. These cams may be of
similar shape, but they are arranged upon the rock shaft so that one will act
slightly in advance of the other. They co-act with a number of levers C which
rest upon their upper surfaces. These levers C° connect with upright rods of
ordinary construction, and the latter in turn are connected with the ends of the
mutes, so that each mute will be shifted by power applied to both its ends. The
only feature of importance in this connection is the one consisting of the mechanism
which by force applied to a single draw or stop rod will raise all the mutes, but
will do so one after the other.
While on the subject of the stop rods it may be well to explain that a rod, C1,
which is similar in construction and operation to the stop rods C, controls the
direction of movement of the wind motor which is employed in the instrument to
move the perforated music sheet, and consequently the direction of the movement
of said sheet. This rod C10 is combined with the stop rods C so that if any one of
the stop rods C is pulled out the rod Co will be automatically moved in, and
conversely, so that each time that the rod Co is moved outwards the stop rods
will be moved in. This is quite an important feature because it is necessary to
pull out the rod C after playing a piece of music in order to cause the music
sheet to be rewound upon the music roll and it often happens with instruments of
ordinary construction that the rod C1 is left out after the introduction of another
sheet of music and the pulling out of stops preliminarily to playing, thus a sheet
of music which has been attached to the take up roll will often be detached and
necessitate the trouble of re-attaching it. As it is necessary to pull out one of
the stop rods before any playing can be done, it is obviously advantageous that
the act of pulling out the stop rod will return the rod C to its normal position.
The means here shown for combining the stop rods with the rod Co comprise a
bar C which extends across the stop rods and is connected by links c¹ to a
stationary part C12 of the instrument. In the present instance the bar C lies on
top of the stop rods rearwards of the stop board C" which is a board through
which the stop rods pass. Preferably the bar C" will be faced with felt or other
soft material on the under side. The links c' are pivotally connected at one end
to the bar C and at the other end to brackets extending from the stop board C¹³.
From the stop rods in the rear of the bar C extend pins c which preferably will
be fitted with anti-friction rollers. These pins are so spaced that when the stop
rods are pulled out, said pins will be moved adjacent to the bar C". At one end
the bar is pivotally connected with one arm of a bell crank lever C" which is
fulcrumed at the middle to a bracket extending rearwardly from the stop board C¹³
and at the other end is forked to engage with a pin c³ extending from the rod C¹º.
It is obvious that if any of the stop rods C occupy their outer positions at the
time that the rod Co is pulled outwardly, the outward movement of the latter
will, through the agency of the lever C18, shift the bar C¹¹ in such manner that
the latter will, by acting against the pins c* of such stop rods, force these stop
rods inwards. It will also be seen that if the rod C is left in its outer position
at a time when one of the stop rods C is pulled outwards, the pin & of the latter
will shift the bar C₁ so as to rock the lever C" in the proper manner to force the
rod C10 inwards.
Besides the stop rods C and the similar rods C³, C10, there is a rod C1 which is
similar in construction and operation. This is connected by a radial pin c* with a
bell crank lever C which is fulcrumed between its ends to a bracket extending
rearwardly from the stop board (" connected with a rod C that serves to control
the wind motor before mentioned, as will be clearly explained when describing
the motor and its appurtenances.
The musical instrument which I have chosen to illustrate the improvement is
provided with a key-board and so constructed that the sound producing devices
may be played either manually or mechanically under control of the perforated
music sheet. The organization is such that all the banks of sound producing

page_text: devices may be played either manually or mechanically. To prevent the accidental
operation of a key while the instrument is being played mechanically, it is
desirable to provide means whereby the function of the keys may be suppressed
during the mechanical playing of the instrument. For this purpose there is a
rod C, which is similar in construction and operation to the stop rods C.
Connected to it is a rod C18 that extends to a rocking bar C. The latter is bent
transversely near its ends and at the extreme ends is bent parallel to its main
portion so as to form journals. By rocking it in one direction the main portion
will rise under the keys. This is accomplished by the drawing out of the rod C¹.
A reverse movement of the rod C" will lower the rod C and leave the keys free
to be used. It may be added here, although in anticipation of what will be more
fully explained hereafter, that the inward movement of the rod C" applies a
cover K to the tracker board L over which the perforated music sheet advances.
I will now describe the valves D which immediately control the speaking of the
reeds. Their construction may be best understood by reference to Figure 7, but
they are also illustrated in Figures 1, 2 and 3. Each of these valves comprises
a block d in one face of which is formed a channel d' which is covered by a strip
of flexible material d that may well consist of leather. The chamber thus formed
is closed at the top by a portion d' of the action frame as may be seen at Figure 2.
The bottom of this chamber communicates with a duct which whenever it is
desirable to cause a speaking of the corresponding sound producing devices, is put
in communication with the wind inducing apparatus of the instrument; the music
sheet being the device which controls the action of such duct. The wind apparatus
and various devices which are intermediate of the music sheet and the said duct
I will presently describe in detail.
I have said enough to make it clear that at times, each chamber, consisting of a
channeled block d' and strip of flexible material will be put into communication
with the wind inducing apparatus. The musical instrument illustrated by the
drawings, is intended to have exhaust bellows and therefore whenever one of these
chambers D, D1, D2 is put into communication with a duct d its flexible strips d
will be forced into the channel d'. When this happens, air is permitted to pass
the outer side of the flexible strip (not that side which is toward the channel d¹)
to cause the speaking of the reed. To control the passage of air necessary for the
speaking of a reed, each flexible strip co-acts with a bridge or rib d³.
As here shown, the back of cach block d (by this I mean the unchanneled side)
has a bridge or rib do formed vertically upon it. At each end of the bridge or rib
the block has a transverse extension de and these transverse extensions of each
block fit against the flexible strip ds of the next adjacent block.
Behind the valves D is a wind chest E which is in communication with the wind
inducing apparatus. Whenever one of the flexible strips d' of a valve D is drawn
into the channel d' of said valve, it will leave the opposite bridge or rib d³ of the
next adjacent valve D and thus establish communication between the wind chest E
and the cell of the reed which corresponds to the thus actuated valve. Assuming
that the mute of such cell is open, atmospheric air will thus be induced to flow
through the reed to the wind chest E.
It may be well now to describe the wind inducing apparatus. F designates
exhaust bellows which may be operated in any suitable manner, as, for instance,
by ordinary pedals. I have only shown a strap fas the means for operating one
of these bellows. It may extend to any source of power. Of course there may
be any desirable number of exhaust bellows and they may alternate in their
operation as usual.
F¹ is an equalizer which as usual is made in the form of a large bellows, fl being
its expansible side. This equalizer communicates by means of a duct or ducts f
with a wind chest G. For the sake of clearness it may be well to call the wind
chest G the main. wind chest and the wind chest E the wind chest for the sound
producing devices.
H designates a chamber capable of collapsing and expanding more or less. It is

page_text: in
shown as made of bellowslike construction but has no valves. It is in communi-
cation with the wind chest E for the sound producing devices. As here shown
the chamber H communicates directly with a chamber H and the latter communi-
cates with a trunk H' which opens into the wind chest E for the sound producing
devices. This chamber H is shown as arranged below the wind chest G
and as communicating with the wind chest G through one or more holes
the latter. For each hole g there is in the chamber H a valve h which is here
shown hinged in place at one end and pressed upwardly by a spring h¹. The
free end of the valve is connected in any suitable manner as, for instance, a
flexible connection with the movable part of the chamber H. The connection
between the valve and the movable part of the chamber H is to be such that
when the chamber H is collapsed to the full extent, the valve will reach its
seat and close the opposite opening g.
I designates a chamber capable of being collapsed or expanded more or less
and made, as here shown, in the form of a bellows but without valves. It is in
continuous communication with the wind chest G. The movable part of the
chamber His connected with the movable part of the chamber I in any
suitable manner as, for instance, by rods J extending outside the chambers and the
wind chest G and connected with the movable parts of such chambers. Whenever
the tension of the air within the wind chest G is sufficient to collapse the
chamber H to the fullest extent, the valve or valves will close the opening or
openings g. Thereupon the communication between the chamber H and the wind
chest. G will be cut off. The upward movement of the movable part of the
chamber H due to the collapsing of this chamber will raise the movable part
of the chamber I, and as this chamber I is continuously in communication with the
wind chest G, said chamber I has a tendency to collapse. This tendency is
exerted through the action of the rods J upon the chamber H.
Whenever it pre-
ponderates it will open the valve or valves and thus establish communication
between the chamber H and the wind chest G. This action will occur almost
continuously, although it will be intermittent and owing to this the valve or
valves will vibrate to and from the opening or openings 9 almost constantly. As
the chamber H is in communication with the wind chest E for the sound producing
devices, there will always be a different tension in the latter wind chest from what
there will be in the main wind chest.
g
It is very important to provide for one tension of air for the sound
producing devices and a different tension for the other parts, as, for instance,
pneumatic valves and pneumatics generally, for in this way the pneumatic valves
and pneumatics may be operated with air under greater tension than would be
suitable for sound producing devices. In some musical instruments it is very
advantageous to operate some of the sound producing devices by, air under
different tensions, and this feature of the present improvement provides for
that as well as for a differentiation of the air tension employed to operate
pneumatics.
The improvement also comprises means whereby the differentiation of air tension
in parts of a musical instrument may be varied at will. Obviously in the apparatus
illustrated in the drawings any force applied upwardly to the movable part of the
chamber I will oppose the action of the wind chest G upon this chamber I, and
hence will tend to change the amount of tension which otherwise would be exerted
by the chamber I upon the wind chest G. Force may be applied upwardly to the
movable part of the chamber I by any suitable mechanical means.
In the present
instance I have shown the movable part of said chamber as connected to a strap I'
which is wound around a rock shaft I that is supported in brackets ', . From
the forward portion of this rock shaft extends an arm and this co-acts with the
küee swell or lever 1, the latter being pivoted by a pin it to a fixed rail of the
instrument. Obviously by moving the knee swell out of its normal position
the rock shaft I may be made to wind up the strap I¹ and thus raise the movable
part of the chamber I. Many other arrangements might be employed without

page_text: departing from the invention for exerting an opposing force to the wind chest G
upon the chamber I.
The perforated music sheet has not been illustrated because it is of ordinary
construction.
The music roll is intended to be supported between brackets M. ID
one of these brackets there will be a shaft that will engage the music roll.
N designates the take-up roll to which the outer end of the music sheet is attached.
The music sheet is drawn along by this take-up roll during the playing and at such
time the shaft previously mentioned as engaging with the music roll runs freely.
After the playing a change of connections may be made so as to allow the take up
roll to run freely and so as to simultaneously impart motion to the music roll
through the shaft with which it is engaged. The mechanism for accomplishing
this may be of ordinary construction. In Figure 9, I have shown that the take up
roll N is provided at one end with a gear wheel n which engages with a pinion n'
mounted upon a shaft n³ which is supported in a rocking frame N', the latter being
pivoted at n and normally pressed upwardly by a spring n', for the purpose of
engaging the pinions n' and the gear wheel n. On the shaft N is affixed, a
pulley N and this is belted to the wind motor. Loosely mounted upon the
shaft N is a pulley Naud-this is -belted to the aforesaid shaft which is engaged
with the music roll. The pulley N is capable of movement lengthwise with the
shaft N and is provided with a clutch piece n which upon a movement of
the pulley lengthwise of the shaft N' may be engaged with or disengaged from ȧ
clutch piece n that is affixed to the shaft N. A bell crank lever N' engages with
a circumferential groove in the clutch piece of the pulley N and serves to move it
lengthwise of the shaft N'. This lever N' is fulcrumed to a pin n. which is
supported by a stationary bracket and is pivotally connected by a pin n' with the
rocking frame N'. The latter has a pin ns over which extends a lever N°. This
lever N° is fulcrumed by a pin to a stationary bracket and at the free end is
connected to a rod- N' which is operated whenever the rod Co is manipulated. It
will thus be seen that the rod C10 determines the direction in which the perforated
music sheet shall be driveu.
.
The tracker board L may advantageously be made of three sections as shown in
Figures 10, 11 and 12, for in this way small perforations may be used in the music
sheet and consequently the width of the music sheet may be less than otherwise
would be necessary and yet the ducts may be made sufficiently capacious to afford
a free passage of air from the music sheet. It will be seen that the tracker.board
is made of three triangular sections, the center one being provided with narrow
vertical ducts and the other sections. being provided. with oblique ducts which
are considerably larger. The divergence or spreading of the ducts accomplished
in this way compensates for the difference in width of the music sheet and the
banks of sound. producing devices with the appurtenances of the latter. The
ducts communicate with ducts in a horizontal board L. The ducts /* may
parallel. And the forward ends are extended beyond the board L and are provided
with openings which are controlled with valves O operated by manual keys.. The
cover K previously mentioned is pulled down over the tracker-board L when the
instrument is to be played manually thus suppressing the action of the tracker
board L. At the same time that the cover K is pulled down upon the tracker-
board the rod C is lowered so as to permit of the operation of the keys. As
already explained, when the cover K is raised from the tracker-board so as to
permit of playing the instrument mechanically the rod C is raised so as to
suppress the keys.
be
The ducts communicate at their rear ends with vertical ducts 1 in a board L³.
Above the board L there is a block L which is provided with vertical ducts l
corresponding to and communicating with the ducts and hence with the ducts of
the tracker-board. The ducts terminate at their upper ends.in chambers there
being one for each duct. Each of these chambers is fitted with a. flexible
diaphragm, on the other side of which is a wind chest L which is common to all
of the diaphragms 18. Each chamber. communicates through a port with the
..

page_text: chamber L. Preferably such port will be provided with a regulating device,
such, for instance, as a screw 10.
There is a duct a corresponding to every duct of the tracker board and thus
corresponding to every duct in the chambers 1. Each duct d' communicates
with a separate chamber d. Each chamber d' has an opening d communicating
with the atmosphere and an opening & communicating with the wind chest L.
In each chamber d' are two valves do d" fastened to a single rod which is
secured to the corresponding diaphragm .
Each time that one of the ducts of the tracker board L or the board L¹ is open
air will pass to the corresponding chamber and force the diaphragm 18 of such
chamber towards the wind chest L. This will cause the corresponding valve do
to close the port ds leading to the atmosphere and to open the port d' leading to
the chamber d. Thus the corresponding valve D will be operated and the corre-
sponding sound producing device caused to speak. When a port in the tracker
board or board L' is closed, the corresponding diaphragm will be reversely
operated and the corresponding valve D will be cut off from communication with
the chamber L and put into communication with the atmosphere. This will cause
the corresponding valve D to close and stop the speaking of the sound producing
devices.
The wind chest L' communicates with a pipe or duct L' which passes across the
trunk H without communicating with it and terminates in a trunk L. This
trunk L communicates with a pipe L' which passes through the chamber H
without communicating therewith and extends into the wind chest G, consequently
the chamber L' is constantly subject to the air of greater tension.
W designates the wind motor. It in communication with the wind chest G
by means of a pipe W¹, but this pipe W' does not pass directly to the motor, but,
on the contrary, to a regulating valve-box W' containing a slide valve W with
which the rod C18 co-acts. By manipulating the rod C in the stop-board the
valve W8 may be shifted to vary the communication of the box W2 with the wind
chest G.
The construction of the valve is immaterial. In the present instance it is rigidly
affixed to its stem and the latter is connected to a rod to against which the rod C,
or an appurtenance thereof, acts.
It will be understood, of course, that as the valve box W' is in communication
with the wind chest G it is subject to air of greater tension.
The valve regulating box W communicates with the wind chest w' of the
motor W. This wind chest is of course in the present instance an exhaust wind
chest.
The motor W comprises any desirable number of double collapsible and
expansible chambers w. Each is of bellows-like construction and has three
boards, two of which are fixed, the third being arranged between the two fixed
boards and being movable between them. The two fixed boards are fastened to
two opposite portions to 10 of a trough shaped block to 207 8. Each of the
chambers has a separate port w in the block 100. Each of these ports
extends from its chamber w³ down through the portion of the block to, to to and
then horizontally through the portions 208 207 of said block. Each of the
chambers to at the other side of its movable board communicates with a horizontal
port too. The ports w° 10 belonging to each chamber w have combined with them
a valve w" which is here shown as made in the form of a slide valve and large
enough to cover the outer ends of both ports w° 10. Such valve has a chamber in
its interior. Opposite the wind chest to a port w extends to the outside of the
block, there being one of these poris for each of the chambers w. Each valve w¹
may either cut off its two ports w w10 or establish communication between either

of these ports and the port w" leading to the wind chest w*.
communication between one of the ports to 2010 and the wind chest w it opens the
other port w or to to the atmosphere. By alternately changing the communication
of the ports ww10 with the wind chest w aud with the atmosphere the movable

page_text: board to cach chamber to will be made to move first in one direction and then
in the other between the fixed boards. Each chamber wo has pivotally connected
to its movable board a bifurcated rod w013 which is also connected with an arm w¹4
extending from a shaft to. On the shaft 5 is a pulley to which is belted to
the pulley N before described. The crank arms w" may be set at an angle of 120
or any other suitable relation so as to cause the movable boards of the chambers w
to operate in succession. A rod w" is pivotally connected at one end with the
crank belonging to each chamber 10 and at the other end with the valve woll
belonging to such chamber and hence constitutes a means for shifting such
valve.
