Improvements relating to Mechanical Musical Instruments, and to
Apparatus whereby the Operation thereof will be Effected or
Permitted upon the Insertion of a Coin into the same.
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 :-
The object of the present improvement is to provide for automatically playing a
musical instrument for a short period upon the introduction of a coin into a
receptacle with which the instrument is provided.
The improvement consists in various combinations of parts which will hereinafter

Similar letters of reference designate corresponding parts in all the figures.
In the present example of the improvement, a reed organ controlled by a
travelling music sheet is employed. This instrument will first be explained and after
that a description will be given of the means whereby it is operated and controlled.
A designates the reed board of the organ. It is provided with a number of reed
cells a, severally communicating at one end with the atmosphere and on their under
sides about midway between their ends with a wind chest A. This wind chest will
Price 1 1/1

page_text: preferably be an exhaust wind chest or, in other words, one in which air will be
rarified by the action of bellows. In each reed cell is a reed A2 of any approved
construction. At the outer end of the reed cells is a damper, A³, extending along
the open ends of the reed cells and almost closing the same.
The communication of each reed cell with the wind chest A' is controlled by a
valve a', here shown as arranged to act against the under side of the top of the
wind chest and fulcrumed in place at one end by means of a pin a², whereby it is
prevented from lateral movement, and by having its extremity extended over a
ledge in the wind chest. The other end of said valve is normally held up against
the top of the wind chest so as to cut off communication between the latter and the
corresponding reed cell by means of a spring at arranged in the wind chest.
Combined with each reed valve a' is a pneumatic motor a', whereby such reed
valve may be opened. The pneumatic motors a' for the different reed valves are
arranged within the wind chest A' and, as here shown, have their stationary boards
fastened to the top of said wind chest in such position that their movable boards
may act upon the reed valves. Preferably the movable boards of the pneumatic
motors will act upon the. reed valves through the agency of screws a inserted in
the free ends of the reed valves, as then provision will be afforded for adjusting the
relation of the reed valves to the pneumatic motors.
Internally the pneumatic motors a communicate with a corresponding number of
ducts a arranged in a rest or tracker board A. A music sheet A' made in the
form of a belt and performed to effect the playing of a number of tunes in succession,
travels over the top of the rest or tracker board and acts as a valve, controlling the
admission of air to the ducts a'. On the passage of air through one of the ducts a',
the corresponding pneumatic motor as will be expanded, thereupon the corresponding
reed valve a will be opened, and, as then the opposite reed cell a will be put in
communication with the wind chest A', atmospheric air will be caused to flow
through such reed cell and the reed therein will be caused to speak.
In addition to the reeds, the organ is shown as provided with a set of sound-
producing devices, here represented as consisting of bells, B. In the principal
views of the drawing, these bells are shown as operated electro-magnetically and
they will now be described as thus operated, with reference more particularly to
Figure 5.
Each bell, B, is supported by a bracket, b, extended from a vertically arranged
board. Its clapper, ', is carried by the armature, 3, of an electro-magnet b³, here
shown as erected upon the bracket b. The armature 62, is supported by a spring
bracket, which removes it from the electro-magnet when the latter is
de-energized. Each clapper may have combined with it a damper which, upon
the retraction of the clapper through the resilience of the spring bracket will
contact with the bell and stop its vibration. .
:
C designates an electric battery or other source of electricity. The electro-
magnets have their coils at one end connected with a wire 6 that is connected with
one pole of the electric battery. The other end of the coils of each electro-
magnet is connected to a separate wire b, which extends to a corresponding contact
piece 8, arranged within the wind chest A. The several reed valves a overlap
the corresponding contact pieces 8, and each of the reed valves has upon the
under side of its overlapping portion a contact piece 4°. When any reed valve is
open, its contact piece will impinge upon the corresponding contact piece 8, and
thereupon the electric circuit will be completed from the wire to such reed valve.
From the contact piece 6° of each reed valve a wire 10 extends to a rod ",
arranged within the wind chest A. A wire 2 extends from the rod to a
screw on the outside of the wind chest and from this screw a wire 4 extends to
a contact piece. Adjacent to the contact piece 15 is a contact piece 61. Opposite
the spaces between these contact pieces 11 is a switch 7, here shown as made
in the form of a push pin. A spring surrounding the pin 617 between a
board and a shoulder with which the pin is provided forces the pin outwardly
so that it does not establish communication between the contact pieces 618 616. By

page_text: pushing the pin 67 inwards, it may be made to establish communication between
the contact pieces 61616, so as to render the electro-magnets of the bells B capable
of operation by establishing communication between the wire 64 and a wire 61
leading from the contact piece to the battery C. Obviously, if the push
pin of the switch is pushed inwards and held in its inward position, each reed
valve when opened will cause the operation of one of the bells B. It is intended
that the push piece of the switch shall be accessible to the public, so that after
anyone shall have deposited a coin and rendered the organ operative, he may cause
the operation of the bells at his own pleasure. This feature renders the instru-
ment additionally attractive because it gives to the person starting the instrument
by depositing a coin the idea that he is participating in the performance.
In Figures 1, 2 and 16 I have illustrated a drum B¹.
It is operated by an electro-magnet 3 similar to the electro-magnets already
described and correspondingly arranged in circuit. As the bells and the drum will
preferably operate repeatedly, each of the electro-magnets 63, has combined with it
a rheotome whereby the magnet will on attracting its armature, break the circuit,
become de-energized allowing the armature to be retracted, and the armature when
retracted will re-establish the circuit only to be broken again upon the attraction
of the armature.
In Figure 17, a mechanism whereby the bells B may be operated without
electricity is shown. Here one end of the wind chest A' is provided with an air
duct a corresponding to each reed valve a'. Outside of the duct as is a casing aº,
which communicates by suitable openings with the atmosphere. A similar
casing at is shown as arranged within the wind chest at the inner side of these
ducts, and provision is afforded by forming suitable openings to enable it to com-
municate with the wind chest. Valves at a co-operate with each of the ducts a³,
the valves a being arranged inside the wind chest and the casing a, and. the.
valves a being arranged outside the wind chest and within the casing a. The
valves a" a of each pair are arranged upon a rod a" which passes through the
duct with which such valves co-operate and also passes through bearings in the
casings a³ a¹º
Each valve rod a¹³ is connected with a bell crank lever a fulcrumed between
its ends to a rail a" arranged within the wind chest and connected pivotally with a
lug extending from the corresponding reed valve a'.
Obviously, the expansion of a pneumatic motor as will on opening the corre-
sponding reed valve a' actuate the contiguous lever at so that the latter will draw
the corresponding valve a" away from the opposite duct a and the corresponding
valve a against the outer end of such duct, thus cutting off the communication
of such duct u with the atmosphere and establishing communication between it and
the wind chest. The collapsing of the pneumatic motor and consequent closing of
the corresponding reed valve will produce a reverse movement of the corresponding
valves a", so that communication of the corresponding duct with the wind
chest will be cut off and communication-between it and the atmosphere established.
This condition of the valves is of course the normal condition.
From each duct as extends a duct a¹ and from each duct a extends a duct or
pipe a to a duct in a board B. The ducts a and b will preferably be provided
with nipples and the pipe a" may be made of soft rubber and slipped over these
nipples to establish communication between the ducts.
The ducts communicate with pneumatic motors 2 arranged upon the top of the
board B. Normally these pneumatic motors will be expanded by springs 1,23
pressing upwards against pins 64 that extend horizontally from the movable boards
of the motors. Rods / extend from the movable boards of the several pneumatic
motors to the clappers 61 of the bells B. The rods pass through holes in the
brackets of the bells and simply rest upon the movable boards of the pneumatic
motors 22
Obviously, whenever a pneumatic motor aº opens its reed valve a¹ and establishes
communication between the corresponding duct 1 and the wind chest A', the

page_text: corresponding pneumatic motor 22 will be collapsed and thus the corresponding
bell B will be sounded, and upon the collapsing of said pneumatic motor a and
consequent closing of its reed valve a¹, the corresponding valves all a¹² will establish
communication between the interior of the corresponding pneumatic motor and
the atmosphere, whereupon such pneumatic motor 62 will be expanded and the
clapper of the corresponding bell elevated.
With the wind chest A¹ is combined an equalizer D, of bellows-like construction
having its immovable board & affixed at one end to the bottom of said wind chest
and its other end fastened by a bracket d¹ to said wind chest. Its movable board
is intended to be forced away from the immovable board by means of a suitable
spring. Communication is established between this equalizer and the wind chest by
means of a pipe d², extending from the immovable board of the equalizer to the
wind chest. The rarifaction of air within the wind chest and equalizer by means of
the bellows which are employed will, of course, induce the partial collapsing of the
equalizer and whenever the bellows action is insufficient to maintain this rarifaction
of the air, the expansion of the equalizer will compensate for their failure so to do,
thus maintaining a substantially uniform pressure. The equalizer may have a relief
valve as usual, so that it may not be subjected to great strain.
The bellows D' which co-operate with the equalizer and wind chest are intended
to be of the suction type. They are shown as having their fixed boards mounted
upon the immovable board of the equalizer D, and they will communicate under
valves of the ordinary or any other approved construction with the equalizer.
Their movable boards are connected by rods d³ with cranks d extending from a
shaft D2 journalled in a frame E fixed in the instrument. This shaft D2 is driven
by a motor mechanism which is operated only after the deposit of a coin.
The shaft D derives motion in the present instance from a shaft F, journalled in
the frame E, motion being transmitted by a gear wheel f on the shaft F to a
pinion on a shaft F1 journalled in the frame E and being transmitted from a gear
wheel on the shaft Fi to a pinion f³ on the shaft D2. The gear wheel fis loosely
mounted upon the shaft F.
On the shaft F a drum F2 is affixed. A pawl is pivotally connected to it and
engages with a ratchet wheel, which is loosely mounted upon the shaft F. The
pawl is held in engagement with the ratchet wheel by a spring. The ratchet
wheel is rigidly connected to the gear wheel, so that when motion is imparted
to such ratchet wheel it will also be imparted to the gear wheel f
Over the drum passes a strap or equivalent device F³, which at one end is
fastened to the drum and at the other end is attached to a weight F' that is
arranged within the case of the musical instrument.
On the drum F2 is, wound another strap or cord F, which passes beneath a
roller journalled in a frame F which is fitted in a vertical guideway F so
as to be free to slide therein. This roller is suspended in a bight or turn of
the cord F³. After passing around it, the cord F5 passes to a drum F mounted
upon a shaft F", here shown as journalled in brackets fastened to the frames E.
The cord passes several times around the roller F and its free end is attached
to a weight F. The drum F is loosely mounted upon this shaft F, so that
it can run free of the shaft in one direction and impart motion to it when
moving in the other direction. It is connected with this shaft by
pawl and
ratchet similarly to the connection which is made between the drum F2 and
the shaft F. This drum F is intended to operate the music sheet or such
other part as in any modification of the improvement may determine the tune to
be played.
On the shaft F10 is mounted a gear wheel F12 which engages with a pinion F15
mounted upon a shaft F1. On the shaft F a gear wheel F15 is affixed which
engages with a pinion F1 on a shaft F. This shaft F17 has affixed to it
gear wheel F18 that engages with a pinion F1 affixed upon a shaft F. On
the latter is mounted a brake wheel F, and a governor F2 here shown as
consisting of a fan whose blades may be twisted or oscillated on the arms

page_text: whereby they are supported, to vary the resistance offered by them to the
movement of the train of wheels comprising the governor. The train of gearing
just described derives motion from the drum F9 when the weight F" descends
and its purpose is to drive the music sheet through the shaft F".
The object of connecting the cord F whereby the drum F is driven with the
drum F is to enable both the drums F F to be rotated together for winding up
the cords FF to elevate the weights. The purpose of the roller F is to enable
the cord F to be wound upon the drum E2 without causing the cord F³ to be
wound upon the drum F when the winding of the cord F5 upon the drum F' is
unnecessary.
G designates a crank handle outside the case of the instrument. It is affixed to
a sleeve, journalled in the frame E and extending through one side or end of the
case of the instrument. It has affixed to it a disc carrying a pawly. This pawl
engages with a ratchety³, which is loosely mounted upon the shaft F. The sleeve
forms a tubular hub for the disc g, and the ratchet wheel g³ has a tubular hub
which is extended into such sleeve and supported thereby. Into the tubular hub
of the ratchet wheel the shaft is extended and it is thereby supported.
for
The ratchet wheel g³ forms one part of a clutch and is provided with pins
engaging with the other part of the clutch g. The part of the clutch is free
to move lengthwise of the shaft F, but is keyed thereto, so that no independent
rotary motion can exist between it and the shaft. The party of the clutch has in
that face which is opposite the ratchet wheel a circular groove go and across this
at diametrically opposite points are radial pins on which rollers are loosely
mounted.
Obviously when the part y' of the clutch is moved beyond the reach of the pins y
of the ratchet wheel, no motion will be imparted by the crank to the shaft F,
but when the part of the clutch is in position to be engaged by the pins g₁ of
the ratchet wheel g³, motion may be imparted to the shaft F by the crank. The
object of the pawl of the disc g' and the object of making one part of the clutch in
the form of a ratchet wheel is to prevent any injury from being occasioned by the
turning of the crank G in the wrong direction.
Whenever the crank G by rotating the shaft F winds the cord F³ upon the
drum F, it also winds the cord F upon the drum F in such direction as to elevate
the weight F, unless that weight shall already have been elevated. It will of
course be understood from what has been explained about the connection of this
drun by a pawl and ratchet with the shaft F upon which it is mounted, that when
such drum is rotated in a direction to elevate the weight I, no motion will be
transmitted from it to the train of gearing which it is designed to drive. In order
that the cord F shall cause the rotation of the drum in a direction to elevate
the weight F, the drum F2 will first have to take up the slack in the cord F* and
elevate the frame F to the top of the guide F in which it works. After thus
bringing the frame 17 to a position of rest, the cord F³ may transmit motion to the
drum F
Now a description of the means for shifting the part of the clutch whereby
motion is transmitted from the crank G to the shaft will be given. A lever is
fulcrumed by a pin y' to a bracket extending from the frame E. The upper
end of this lever 8 is forked so as to embrace the hub of the part of the clutch
and is provided with two pins that enter a circumferential groove in the hub of this
part of the clutch. Obviously, this connection of the lever with the part of the
clutch enables the lever to shift the said part g lengthwise of the shaft F and yet
not interfere with the rotation of said party.
The lever is oscillated to shift the part of the clutch by means of a vertical
rod sliding in suitable bearings. Near its upper end, this rod is provided
with a collar or projection g" and near its lower end it is furnished with a similar
collar or projection y". A spring "attached to the collar or projection g¹³ and to
a fixed portion of the instrument returns the rod ". When the weight is in its

page_text: lowest position a tappet ƒ, with which this weight is provided, acts upon the
collar or
projection of the rod g" and holds this rod in its lowest position. The
descent of the weight F adjusts the rod "into this position. When the rod g" is
in its lowest position, the part g³ of the clutch will be shifted into position for
engagement with the other parts of the clutch, and hence at this time the crank G
will be capable of imparting motion to the shaft F. The spring g' is so light that
after the crank begins to transmit motion through the parts of the clutch to the
shaft F, such spring will be incapable of disengaging the part from the other
part of the clutch. As soon, however, as the tappet 10 of the weight reaches the
collar or projection gl² of the rod ", the rod g₁ will be raised and the part of
the clutch will thereby be disengaged from the other part of the clutch. Owing
to this, it will be impossible for the crank G to impart any further movement to the
shaft F until after the weight F shall have descended to its lowest position again
and thereby have restored the engagement of the part g with the other part of
the clutch. This is an important feature because it prevents any person from
maliciously injurying the instrument by turning the crank in a direction to wind the
cord F³ on the drum F2 when this should not be done.
The train of gearing which begins with the drum F and ends with the brake
wheel F is controlled by a brake H, and such brake is sufficient to restrain this
train of wheels from movement even after the raising of the weight F. The
introduction of a coin causes the brake H to be relaxed, permitting the weight F
to descend and operate the train of wheels and thus drive the music sheet.
16

Before describing the brake in detail, it may be well to explain the means which
impart motion to the music sheet. On the shaft F is a roller 12. The music
sheet passes under the roller 12 and afterwards around it and over the upper portion
thereof. Above the roller f is a roller 13 which holds the music sheet in contact
with the roller/ 13
12
so as to insure the transmission of motion from the roller to
the music sheet. The roller f13 is supported in a swinging frame f" hinged at f15
to a fixed part of the instrument. A spring presses this frame downwardly so
as to produce the requisite downward pressure of the roller 13. Preferably the
music sheet will be held down upon the rest or tracker board A4 by means of a
roller extending from a rock shaft 18 and impelled downwardly by gravity,
aided if desired by a spring. The music sheet is quite long and takes the course
indicated by the dotted line composed of alternate long and short dots in Figure 2.
It will be seen that it passes into a box A. The side a of this box is removable
to facilitate the insertion or removal of a music sheet being secured in place by
pins a at the bottom and a spring catch a at the top. It may be removed and
replaced, and so may a music sheet, through a door a³, provided at the front of the
case of the instrument. Guides A7 A8 will direct its movement as may be necessary.
Its upper portion is supported by an arc-shaped piece A', which will prevent it
from improper contact with the rolls which are combined with it.
As the music sheet is drawn from the bottom of the box A under a tension due
to the weight of its folded portion the draft on the music sheet will be uniform and
the playing of tunes will consequently be in good time.
The brake H will now be described. It is shown as consisting of an arc-shaped
piece conforming to the brake wheel F" and carried by a rod h, extending from a
rock shaft h¹. As here shown, this rock shaft is rectangular in form and the rod h
has its end inserted within the rock shaft. A spring fastened at one end to a
fixed part of the instrument and at the other end impinging upon the rod, tends
to force the brake upon the brake wheel. In line with the rock shaft h¹ is another
and similar rock shaft, and from the latter extends a rod h³. From the rock
shaft, an arm extends under the arm which carries the brake H. When
the rock shaft 10 is rocked so as to elevate this rod and arm ", the latter will
raise the brake from the brake wheel and release the train of gearing comprising
the brake wheel so that the music sheet may be propelled. When the rock
shaft 10 is oscillated in the other direction, it will allow the brake to drop upon the
brake wheel.

page_text: The rod, it will be seen, has its outer end upwardly inclined, so as to form a
cam-like portion *.
1 designates a horizontally-sliding carriage working in clips. Its movement
in one direction is restricted by a stop block .
It is moved and normally held
into contact with this stop block by springs *. At one end the carriage has
connected to it a cord which passes around a pulley supported by a fixed part
of the instrument. The cord after passing around the pulley, is connected by
a spring with one end of lever, fulcrumed by a pin to a fixed part of the
instrument. The spring obviates breakage which but for its use might be caused
by shifting the lever at a time when the carriage was blocked by the insertion of
some device.
The free end of the lever is provided with a transverse pin that projects in the
path of the weight F and whenever the weight is raised to its highest position,
it will elevate the free end of the lever, and by depressing the other end of the
lever, will move the carriage I away from its stop 3.
A chute K made only large enough to receive a coin of the proper size extends
to the outside of the instrument, and from it the coin passes to the carriage.
The carriage has a receptacle suitable for receiving and holding a coin of that
denomination which is intended to be collected before the instrument can be operated.
The coin receptacle 10 consists of a slot.
The movement of the carriage by the cord will produce no effect upon the
rod unless there is a coin in the coin receptacle. Whenever the carriage is
moved with a proper coin in its coin receptacle, the coin will act upon the incline
or cam-shaped end of the rod h³, and, by raising the rod ³, will tilt the rock
shaft and elevate the brake H from the brake wheel. On the movement of the
carriage the coin will slide along and will drop into a chute J, and thence pass into
a bag J or other coin receptacle. A coin smaller than the proper coin will drop
through the machanism and never reach the coin chute.
That end of the carriage which has the cord attached to it is bifurcated and
has its extremities crossed by a bridge ¹. The rod ³ when tilted upwards comes in
contact with this bridge. The rod carries an arm 3 which rises from the rod and
then extends parallel with it toward the carriage. A coin deposited carried by the
carriage will elevate the rod 3. After the passage of the coin into the chute.]
the rod 3 will fall but as the bridge will then be under the arm it will prevent
the rod from immediately descending to its normal position and releasing the
brake too quickly.
The coin chute K is intended to discharge its coin upon a lip extending from
a bracket erected upon the carriage, and having at the upper end a portion
which extends beneath the chute K whenever the carriage is moved out of its
normal position and thereby serves to support a coin in said chute until the carriage
resumes its normal position. Opposite the lip a slot is formed in the bracket
and through this the coin passes. It will then be guided to the coin receptacle of
the carriage between the lower part of the bracket and an upright bracket ¿¹
erected upon the platform " along which the carriage travels.
The movement of the bracket away from the bracket allows anything which
may have been improperly inserted between them to fall down below.
The lower part of the bracket " is slotted to permit the rod ³ to pass through it.
Although after the discharge of a coin from the carriage I, the return of the
carriage to its normal position and the descent of the weight F below the pin of
the lever, the rod will be free to descend and on descending will render the
brake H capable of returning to the brake wheel F, yet the brake will not at this
time contact with the brake wheel unless the tune last played shall have been com-
pleted. A description will now be given of the means whereby the brake is
prevented from co-acting with the brake wheel previous to the completion of a tune.
It will be seen that the rock shaft has an arm 30 extending from it and that the
free end of this arm is provided with a roller 31, which is located above the rest or
tracker board A'. Just below the roller 31, the rest or tracker board has formed

page_text: in its upper surface a cavity of suitable size for receiving such roller.
Near one
edge the music sheet A is provided with perforations located one in rear of the end
of each tune. An imperforate portion of the music sheet will support the roller ³¹
and so prevent the descent of the brake H upon the brake wheel until a perforation
is moved beneath the roller, whereupon the roller will sink into the cavity provided
for its reception in the rest or tracker board and the brake will contact with the
brake wheel and stop the propulsion of the music sheet.
On the descent of the roller into the cavity provided for its reception in the
rest or tracker board, it contacts with a lever which is fulcrumed between its
ends, has a valve located at one end and has the other end extended under the
arm The valve carried by this lever closes a duct 33, and from the latter a
pipe extends to a pneumatic motor ³ (see particularly Figure 6), arranged in
the wind chest A. When the valve of the lever is raised, air is permitted to
blow through the duct 3 and pipe into the pneumatic motor 5, and the latter
is expanded. When this happens, the movable board of the pneumatic motor 35
acting through a pin ³ raises a valve and thereby admits air into the wind
chest A', thus preventing the bellows from producing any effect if they should be
moved by the raising of the weight F by some person without depositing a coin,
and the subsequent descent of said weight.

tion, and in what manner the same is to be performed, as communicated to me
