Improvements in Governing Mechanism for Mechanical Musical
Instruments and other Apparatus.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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:-
This invention relates to mechanical musical instruments, in which perforated
sheets of paper are used in combination with a series of air ducts or passages
leading to musical reeds pipes or other sounding devices, or to mechanism for
operating the sounding devices which are caused to sound by the exhaustion or
pressure of air, all of which musical instruments are well known.
Heretofore it has been very difficult if not impossible to run two perforated
music sheets, each operating a separate and independent musical instrument,
synchronously or together for the two musical instruments controlled by the two
perforated music sheets to play together in unison, the difficulty being caused by
the tendency of one of the music sheets in travelling over the air ducts for the
operation of the sounding device, to get ahead or in advance of the other, by
which the perforations in such advanced music sheet would cause its sounding
devices to sound before those in the other music sheet; this occurs from a variety
of causes well understood, and needing no particular description herein, and the
abject of the present invention is to combine mechanism in such a manner with
the travel of two or more perforated music sheets, each controlling a separate or
independent organ or bank organ, or other musical instrument, that the two or
more music sheets will run or travel synchronously or together, in such manner
that the music played on the several organs, or bank organs, or other musical
instruments controlled by the perforated music sheets will be rendered synchronously
or together in point of time, enabling for instance, on one organ, or bank organ, or
other musical instrument, the accompaniment to he played and a solo or the melody
or other part to be played on another organ or bank organ so that the musical
picce being played by the several instruments would be performed together, or in
the same time, and the invention consists in combination, of two or more organs, or
hank organs, or other musical instruments, each operated or controlled by a separate
or independent perforated music sheet, and means for controlling the movements of
each of said perforated music sheets, so that the two or more perforated music
shects will travel together, or in the same time, for the playing of the two or more
organs or other musical instruments synchronously or together, all substantially as
hereinafter fully described; and the invention also consists in the construction and
arrangement of the various parts of the apparatus for carrying out this invention
all substantially as hereinafter fully described, reference being had to the
accompanying sheets of drawings in which is illustrated the present invention, as
arranged to operate the sounding devices of two separate and independent musical
organs, or bank organs, or other musical instruments by two separate perforated
music sheets, the musical instruments not being shown.

page_text: These drawings represent two perforated music sheets, each being arranged to
operate in connection with all the necessary parts for running the same for a
separate organ, in connection with the parts of the present invention, the parts of
one being the dupliente of the other, and arranged one above the other, the upper
one representing one set or system and the lower one the other set or system and
both substantially lettered alike, the description of one answering fully for both:
there heing also shown parts which connect the two systems together for each to
be governed by the movements of the other to cause the travel of the perforated
music sheets over the raceways or tracker ranges to be synchronous or simultaneous,
so that the music of both organs or other musical instruments will be played
together for the proper performance of the music arranged thereon.
In the drawings, Figure 1 is a central vertical section of the operating parts of
this invention, in connection with two perforated music sheets, and their operating
mechanism, with parts broken out, and in side view, for the operation of two
perforated music sheets in accordance with this invention;
Figure 2 is an end view,
Figure 3 is a partial vertical section of the upper set or system and a front view
of the lower set or system showing some of the parts in different positions from that
shown in Figure 1.
In the drawings A represents a perforated music sheet in the upper set or
system, and A' the perforated music sheet in the lower set or system, each secured
to a separate music or delivery roll B, and adapted to travel over a separate
tracker range or raceway C, and to he wound upon a separate take up roll D in
the operation of the instrument, each raceway Chaving a row or series of air ducts
or passages E, the passage of air through which, when connected to the musical
part of the instrument, causes the reeds, pipes or other sounding devices to sound
by the exhaustion of the air all substantially as usual in mechanical musical
instruments and needing no particular description herein.
In the drawings, the music sheets, the music and take up rolls and raceway are
shown as broken off, the parts not being shown at one eud, but constructed and
arranged as usual in such instruments.
The journal a of the music roll is detachably secured at its end to a short
shnft F, adapted to turn in hearings in arms b, of a bracket G, secured to the main
board or support H, and having on its end a pulley J, the turning of the said
shaft F turns the music roll with it,
The take up roll D is arranged by its journal d to turn in a bearing of a
bracket K of the support H, and secured on the end of the roll is a gear L which
is arranged to engage with a small gear or pinion M on the end of a short shaft N,
arranged to turn in bearings in arms e of a bracket P, secured to the supporting
board and having secured to its other end a friction clutch or disk Q.
R is a shaft axially in the same line as the shaft N and arranged to turn in
bearings in arms secured to the support and to move longitudinally back and
forth therein within certain limits.
On the end of this shaft R is a friction clutch or disk S which is opposite the
other clutch Q on the shaft N and is arranged to bear against the said clutch and
be held to such engagement by a flat spring T secured at g to the support. H, and
bearing by its free end against the outer cud of the shaft R.
The shait R of the lower system has two pulleys U, V, secured to it, one V of
which is the driving pulley and is to be connected by a belt, to any suitable motive
power, and the other pulley U is connected by a belt not shown to another
pulley W secured to the shaft R in the upper system, by which motion is
communicated from the lower shaft R to the upper shaft it so that through the
gear e nnections, with their respective take up rulls D these rulls are turned to
wind their respective perforated music sheets thereun, and to cau-e the music sheets
to travel over their respective raceways or tracker ranges C.
The outer end of each perforated music sheet is arranged for its convenient
attachment to and detachment from its take up roll in the usual manner, as is well

page_text: known in these mechanical musical instruments and which is not deemed necessary
to more particularly describe or show in this application.
The music sheet is first wound upon the music roll and its outer end secured to
the take up roll, and in the operation of the instrument, the music sheet travels
over the raceway and is wound upon the take up roll, and when all woun thereon
it is unwound therefrom back on to the music roll, its end detached from the take
up roll, when the music roll with the music sheet is removed from the instrument
and another placed thereon, for the playing of another tune as usual.
The rewinding of the music sheet upon the music roll is accomplished by
mechanism arranged on the shaft R, the moving of which puts the shaft in position
to he turned in the opposite direction, for the turning of the music roll in the right
direction to reverse the movement of the music sheet, the shaft F connected to the
music roll being operated by a belt not shown, which runs over a pulley Y on the
shaft R and another pulley J on the shaft F and when the music sheet is entirely
rewound upon the music roll, the shaft R is put in proper connection again to turn
the take up roll as before, all of which is as usual in these musical instruments
and needs no particular description herein, as it is no part of the present
invention.
B' is a box secured to the support and having a chamber C' from which the air
is exhausted through a pipe D by any suitable air exhaust mechanism, and such
as is generally employed in these musical instruments.
In this chamber C is secured by one of its sides a small pneumatic hellows E
its other side or board m being free to move to and from it, as usual, and on the
end of this board m is secured a strip n, to the outer end of which is secured a
stem or rod which extends outward through an air passage or opening G' in the
side or wall H' of the box and arranged to be guided in its movements in a
bearing in an arm secured to the box side H¹ the rod extending beyond the
arin Jhaving a shoulder or head r with a spiral spring on the stem between the
arm J'and the head to hold by its tension the rod outward, and thus the pneumatic
bellows E closed, as shown in Figure 1.
On this stem Fare secured two disks or valves K', L'; one within the
chamber and the other L outside thereof, to respectively close or open the
passage G to air passing into the chamber, as the one K', or the other L' respec-
tively bears or rests close upon and over the opening G in the movements of the
pneumatic bellows E'.
M is an air passage through the side H' of the box into the pneumatic bellows E
in which is inserted a small tube u which projects outwardly therefrom.
Near the end of the raceway or tracker range C beyond the line of air
passages E, is an air passage N extending inward a ebort distance and then
longitudinally outward to the end of the raceway in which is inserted a tube v
which projects outward, its end being connected to the outer end of the short
tube in the passage M to pneumatic bellows, by a short piece of preferably
flexible tubing io.
From the middle of the passage G is a passage P extending through the
side H and lower end of the box B and open through the other side of
the box into a large bellows Q' which is secured by one of its leaves y, to the
outside of the box.
To a block a' secured to the movable leaf R' of this bellows Q is pivoted at 64
by one end a link S', its other end being pivoted at d' to a vertical lever T pivoted
at el to an arm U₁ of the support, the lower end of this lever being forked as at f
Figure 2, and freely straddling the shaft R, and arranged to hear at such end
against the side of a collar V' secured to the shaft R by a set screw g'.
To a block secured to the movable leaf R of the bellows Q in the upper
system is pivoted at m' one end of a link g' pivoted by its other end at n² to the
upper end of a vertical lever W which is centrally pivoted at r to the support,
its lower end being pivoted at to one end of a link A' pivoted by its other

page_text: end at u¹ to a block to the movable leaf R' of the bellows Q' in the lower system
as shown.
In each perforated sheet near its edge w and extending along the length of
the same at any desired regular intervals, and preferably in the same relative
positions in relation to the perforations representing the music in the sheets, are
perforations B2, and in each sheet these perforations B are arranged in such a
line longitudinally on the sheet, that in its travel over the raceway or tracker
range, they will in succession pass over the opening or passage N¹ in the raceway
or tracker range.
In locating these perforations on the music sheet it is preferable to have one
at the beginning of each measure of the music, but such locations must be the sume
in all the music sheets used.
With the parts in the positions shown in Figure 1, with the air exhaust
mechanism of the musical instruments in operation, if the two music sheets are
then caused to travel from their music rolls to their take up rolls as their
perforations pass over their respective air ducts in the raceways, the music
represented by the perforations in both music sheets will be played synchronously
or together, but it, for instance, the upper music sheet should get somewhat ahead
or in advance of the lower music sheet, so that one of its marginal perforations B
would arrive at aud be over its air duet N' in its rareway before the same locative
marginal perforation B2 in the lower music sheet would reach its corresponding
air duct N', immediately air will pass down the air duct N' in the upper raceway
through its connecting tubes e u into the pneumatic bellows E', opening the same
and moving the valves K' and L' to open the passage G. to the air chamber C
and close such opening to the outside, as shown in Figure 3 in the upper system and
in such operation if these two valves, air would be exhausted from the bellows G
through the passage P into the exhaust chamber C, closing the bellows Q', which
would swing the lever T connected thereto and cause its forked end to press
against the collar V on the shaft K, and move the shaft longitudinally outward
against its spring T, and with it, its clutch S, away from its opposite clutch Q
disconnecting the two clutches, when instantly, clutch Q and its shaft N would
cease revolving, causing the take up roll B in connection there with by its gear
and music sheet A to stop. at the same time the hellows Q would move the
lever W for it to open the lower bellows Q operating the lever Tattached to
it, for its forked arm to be moved back from the collar V on its shaft R leaving
this lower shaft free for the pressure on it of its spring to hold its clutch S, in
contact with the clutch Q, on its gear shaft N, and thus keep the lower take up
roll in motion, until its music sheet moves sufficiently for its marginal perforation B³
to come over the air duct N', in its raceway, when immediately, air passes down
through such air duct, through its tubes into the pneumatic bellows E', and
opening it moves the valves K, L, to respectively open the passage to the
exhaust chamber and the passage P leading to the bellows closing the
bellows by the exhaustion of air therefrom, swinging its lever T¹ for its forked
arm, to move and press upon the shaft collar V, at the same time the lower
arin of the lever W is swung inward, moving its upper arm outward and opening
the upper lellows Q causing its lever T to swing for its forked arm to move
back and from the collar Vi on its shaft, allowing the spring T to move the shaft
inward and thus its clutch S against and in contact with the other clutch Q,
communicating motion to its shaft and gear, turning the music roll and moving
the upper music sheet, which motion will then be in unison with the lower music
sheet, and so continuing until either one or the other gets in advance again, when
the same movement of the pneumatic bellows and levers takes place, and disengage-
ment of the clutches, stopping whichever music sheet is in advance, until the other
catches up with it as described, when through the movement of the lever W¹ an
equilibrium is again established between the two systems, when they continue in
unison as before, and so on.

page_text: In Figure 3 the clutches in the upper system are shown as disconnected, and the
clutches in the lower system as connected indicating that the music sheet in the
upper system is at rest, and the music sheet in the lower system in motion; and
that as soon as the music sheet in the lower system has moved into its position
of unison with the upper music sheet, causing its pneumatic bellows and l-vers
to operate as above described, the parts will resume their same relative positions,
as shown in Figure 1, when the two music sheets will travel again in unison as
before.
Just below the passage N₁ in the upper raceway is a passage D' which extends
inward and then longitudinally outward to the end of the raceway alongside of the
passage N1, and has a small tube y' in its outer end, to which is secured a tube a²
preferably flexible, which extends downwardly therefrom, its other end being
secured to a short tube 2 which is inserted in a passage in the side E' of the
lower exhaust chainber box B which passage d' extends therein and then turns
and opens into a pneumatic bellows F secured in the exhaust chamber C to its
side opposite to the pneumatic bellows E', and in such position as to bear as it is
opened, against the pneumatic bellows E¹ to close it.
Also just helow the passage N¹ in the lower raceway is a similar passage D'
which extends inward, then outward toward the end having a tube
to which
is secured a tube a² preferably flexible which extends upward, its other end being
secured to a short tube 2 in a passage d' in the sile E2 of the upper exhaust
chamber box B and communicating with a pneumatic bellows F secured in its
exhaust chamber to its side opposite to its pneumatic bellows E' and in position
to bear as it is opened against the pneumatic bellows E' to close it.
The object of this part of the invention is to ensure the operation of the
pneumatic bellows E' in each system in restoring the equilibrium of the two
systems, by the travel in unison of the two music sheets, if one or the other
should be in advance. If the marginal perforation 13 in the advanced music sheet,
comes over the passage D in its raceway, air enters such passage and passes along
through it and its connecting tubes to the pneumatic bellows F2 in the opposite
system, and opening the same it presses against its opposite pneumatic bellows E',
and assists in closing it. This ensures the operation of the pneumatic bellows E
in either system, to cause the disconnection of its clutches, when the music sheet
in the system opposite thereto, is in advance, and also ensures such operation
of the parts in case the marginal perforation B2 should by any reasou become
enlarged, which culargement would interfere with action of the pneumatic
bellows E,
This invention is applicable as well to control the travel synchronously of two
or more sheets of flexible material for any purpose other than mechanical musical
instruments and therefore the invention is not to be limited to its application to
mechanical musical instruments.
This invention is shown in the present instance to be used in connection with
musical instruments operated by the exhaustion of air, preferably by the main
exhaust bellows of the musical instruments, but it is not intended to limit the
invention to its operation by the exhaustion of air, as it can be operated as well
by air pressure, or force bellows, in such case the parts being changed for such
force bellows in ways that are well known by makers of such musical instruments
and needing no particular description herein."
The clutches S and Q in the present instance are frictional clutches, which are
preferable for obvious reasons for the instruments which this invention is specially
to be applied, although as is obvious any suitable clutch can be used to communicate
motion from one shaft to the other.
The operation of this invention as described for two or more perforated music
sheets, operating two or more separate musical instruments, is so quick and responsive
in its action, that even if any of the perforated music sheets does get in advance
the perforated music sheets practically travel together or as one, so that the
musical composition played by the musical instruments applied thereto, or

page_text: connected therewith, is played synchronously and accurately in reference to
its tinie.
