Improvements in Automatic Mechanical Musical Instruments.
I, GUSTAV ADOLF BRACHHAUSEN, of 76, Commerce Street, Rahway, in the
County of Union and State of New Jersey, United States of America, Manu-
facturer, 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:-
My invention relates more particularly to automatic mechanical musical instru-
ments in which separate note discs or sheets are automatically fed to and from
operative position.
The object of my invention is to provide a musical instrument wherein the
note disks or sheets can be automatically fed to and from operative position either
successively in accordance with a predetermined arrangement, or wherein any
desired disk or sheet may be conveyed out of its order to operative position, and
wherein the various operations of the parts are brought about with the utmost
accuracy and precision. A further object of my invention is to provide a compact
instrument of the character specified wherein there is no liability of injury to
the device or the note disks used therein, and wherein the proper automatic opera-
tion of the parts will occur under all conditions and circumstances.
To these ends my invention consists in the novel arrangement and combination
of parts hereinafter described and claimed.

sponding parts in the various views.

together with the cams which operate the same.
I will first give the general outline of the operation of an automatic musical
instrument embodying my invention and will then proceed to give a detailed
description of the mechanism and the operation of the individual parts.
The entire apparatus is automatic in operation, it merely requiring the inser-
tion of a coin or the movement of a starting lever to bring about the operation
of the instrument and the insertion of a coin or a shifting of the starting lever
after each tune has been played will automatically cause the instrument to play
a tune different from the last preceding tune. Thus, when a coin has been
properly deposited in the instrument or a hand operated starting lever has been
moved, the parts are set in operation and the note disk carriage will be auto-
matically moved to bring the note disk next to the last one played into a position
to be conveyed into the operative position by the disk transporting mechanism.
The carriage is then automatically locked against movement and the transporting
mechanism moves the disk into operative position where it is clamped in position
and makes one revolution around its pivot. After the note disk has completed
a revolution the clamping means are withdrawn and the disk is lowered into
its place in the carriage and the parts come to rest and are ready to be again
operated by the insertion of a coin or by moving a hand operated starting
lever.
Special reference. being had to Figures 1 and 21 it will be seen that the entire
mechanism is contained within a casing 1, which may be provided with a suitable
door 2 to give access to the instrument when occasion requires. The casing may
likewise be provided with a coin cliute or drop 3 which extends to the outside
of the casing to allow of the insertion of a coin which preferably first passes
through a suitable coin tester (not shown), and, is conveyed through said coin
chute to the coin tray 4 of a starting lever 5. The starting lever may, however,
be the usual or any suitable hand controlled lever projecting to the outside of
the casing and one form of which will be hereinafter described.
t

page_text: Within the casing 1 is mounted a bed plate 6 which carries the sound pro-
ducing instrument which consists in the present instance of steel combs
(Figure 3) the teeth of which are adapted to be vibrated by a series of star-
wheels S (Figures S and 12) that are rotated by projections 9 on a note disk or
sheet 9 (Figure 3). The note disk 9* is provided with a rack 10 that is adapted
to be engaged by the substantially semiglobular studs 11 of a driving wheel 12
(Figure 17). When a note disk 9, is elevated into the operative position, as
indicated in Figures 1 and 6, a movable note disk pivot 13 is automatically pro-
jected through a central aperture in the note disk and a presser bar 14 carrying
anti-friction rollers 15, is automatically moved towards the note disk and the
anti-friction rollers bear thereou to clamp it in the operative position on the
pivot 13 (Figure 6); at the same time causing the rack 10 to engage the driving
wheel 12, as indicated in Figure 12. The clamping action of the presser bar 14
is automatic and positive and in order to provide against injury to the instrument
or the note disk should a stud 11 on the driving wheel engage the imperforate
portion of the rack 10 when the presser bar causes an engagement of the parts,
I employ the means illustrated in detail in Figure 16 of the drawing. In this
figure it will be observed that a central rod or bearing 16 is carried by the presser
bar 14 and on this bearing are supported longitudinally movable heads 17 which
project in opposite directions, and are beveled as indicated at 17*. These
heads are normally maintained in the projected position by springs 18 which are
preferably surrounded by sleeves 19 and the movement of the heads in the pro-
jected position is limited by a pin 20 carried by the rod 16. Between the movable
heads 17 is carried a roller 21 which is preferably grooved on the periphery to
receive the teeth 11 of the driving wheel 12 and the supporting faces of said roll
are preferably beveled inwardly so as to present co-operating faces against which
the said heads are adapted to bear. By this means it will be observed that as long
as the strain against the periphery of the roll 21 is less than the tension exerted
by the springs 18, the parts will remain in the position shown in Figure 16.
However, should the strain upon the periphery of the roll become greater, than
the tension of the springs 18, as when a stud II on the driving wheel 12 meets
an imperforate portion of the rack, the periphery of the roll 21 will be forced.to-
wards the rod 16, thereby forcing the heads 17 from the roll and against the tension
of their springs. As soon as the obstruction is passed or a proper engagement of
the driving wheel with the rack is had the roll will again automatically resume
its normal position as represented in Figure 16. By making the studs on
the driving wheel semi-globular in form the studs are capable of moving over the
full or imperforate portion of the rack 10, should they by accident be brought
into engagement therewith. when movement is imparted to the driving-wheel,
whereas under similar conditions the usual form of conoidal stud might be more
liable to puncture the disk without sliding over it.
When a note disk is being moved to and from operative position in the instru-
ment, there is a liability of the teeth 9 on the note disk coming in contact with
the teeth of the star-wheels, which results either in producing a series of un-
harmonious sounds or in breaking off the note projections on the disks. In order
to provide against any such contingency I employ the following instrumen-
talities.
Special reference being had to Figures 5 and 6, it will be observed that a
bushing 22 is secured to the bed-plate 6. This bushing is adapted to receive a
sleeve-like extension 23 of a guide or shield plate 24, and the sleeve-like
extension is adapted to receive the movable note disk pivot 13 and to allow said
pivot to be projected through and beyond the face of the shield, as represented in
Figure fi. The shield is provided with suitable means to prevent it from rotating,
such for instance, as the pin 25 which projects into a hole 26 and the springs 27
normally maintain the shield in the projected position. The lower portion of
the shield is preferably bent inwards, as indicated at 28, so that should a note disk

page_text: contact therewith, it will be guided to the outer face of the shield and be pre-
vented from catching behind it. It will thus be observed that the shield will
be maintained beyond the line formed by the tops of the star-wheels when the
parts are in the position of rest indicated in Figure 5 and that when the note
disk is moved up into the operative position the teeth of the disk will be pre-
vented from coming into contact with the star-wheels. When, however, the
presser-har 14 is moved inwards the shield will be moved against the tension
of its springs and the note disk will be moved to a position where the teeth
thereof may engage the star-wheels.
In addition to the shield 24, a movable gravity guide may be provided. In the
present instance this guide consists of a sleeve 20 which carries a grooved roller 30
and is mounted upon an inclined rod 31 which may be mounted upon the shield 24.
When the note disk is raised the upper edge thereof will be guided to the groove
of the roller 30 and as the disk is raised further it will carry the gravity guide
up with it. This movement of the guide will cause the upper end of the note disk
to be deflected outwardly by reason of the inclination of the rod 31. The outward
.deflection of the top of the note disk will cause the note disk to be maintained
in contact with the rollers on the presser rod 14 and will thus prevent the teeth of
the note disk from coming into contact with the star-wheels.
In place of or in addition to the hereinbefore described mechanism for prevent-
ing the note teeth from contacting with the star-wheels when the note disks are
being moved to and from operative position, I may employ the device shown in
Figures 19 and 20, from which it will be seen that a segmental protector bar,
guide or shield 32 is connected to arms 33 that are pivoted at each end of the
standard of the star-wheels and preferably on the axis of revolution of said star-
wheels. To one of these arms is connected a crank arm 34 to the end of which is "
pivotally connected a link 85 which is pivoted at its opposite end to a crank
arm 3G carried by and adjustably connected with the rock shaft 37. It will
thus be observed that a partial rotation of the rock shaft in the direction of
the arrow will cause the bar 32 to be moved out of the full line position
represented in Figure 19 to the dotted line position, thereby carrying the
bar out of the position where it will prevent the teeth on the note
disk from engaging the star-wheels. The oscillation of the protector bar 32
to the dotted line position takes place at the same moment that the pivot 13 is
moved outward and the presser rod 14 is moved in to clamp the sheet in position.
The presser bar and the pivot are both operated from the rock shaft 37, as will
be hereinafter described, so that the simultaneous movement of the protector
bar 32, the pivot of the note disk and the presser bar is effected.
Two drums or spring motors are preferably employed to bring about the various
operations of the parts. One drum 38, which I term the main drum merely
rotates the note disk driving wheel 12 to cause the playing of the musical instru-
ment proper. The second drum 39, which I term the auxiliary drum, effects an
operation of the various instrumentalities to bring about the movement of the
note disk carriage, the movement of the note disk to and from operative position,
the movement of the note disk pivot and presser bar to clamp the disk in operative
position and to release the same, etc., etc. Mechanism which will be hereinafter
referred to is provided for stopping one drum or motor when the other is set
in operation. The main and auxiliary drums together with most of the mechanism
co-operating therewith, are carried by the single casting 40 which may be
secured to one side of the casing 1, as indicated in Figures 3 and 8. By these
means the parts are so disposed that they lie comparatively close to and most
of the weight is borne by, one side of the casing, where ample support is afforded
for the mechanism.
The main drum is wound by a handle 41 (Figures 1 & 2) which is adapted to
engage a winding post 42 that carries a pinion 43 which engages the winding
gear. This gear 44 which is connected to the inner end of the spring (not
shown) is prevented from backward movement by suitable pawls 44 which

page_text: engage therewith while the drum itself is provided with the usual circumferential
gear 45, which gear meshes with a pinion 46 connected with a gear 47 that
engages the pinion 48 on the driving wheel 12. A suitable train of gear is
likewise driven by this gear 47, as indicated in Figure S, and thus communicates
motion to the governor 49, preferably of the character represented in Figures 9
and 10. The governor 49 is provided with an arm 50 which is held friction-
tight at its flattened portion 51 and the arm is bent at right angles, as indicated
at 52. By this means a stop arm is provided for the governor which is rigid in
construction and is not liable to be bent aside when it is suddenly brought into
engagement with its stopping lever, as is the case with governors of the ordinary
construction. The drum 38 is provided upon one side or end with oppositely
disposed pins 53, as indicated in Figure 8, for purposes which will hereinafter
appear.
A half revolution of the auxiliary drum or motor 39 brings about the
operation of the various parts of the device except the rotation of the note disk
around its pivot, which rotation is produced by a half revolution of the main
drum. The main and auxiliary drums are preferably of such relative power that
a single winding of the main drum will effect a rotation of all the note disks in
the carriage and a single winding of the auxiliary drum will effect a corre-
sponding number of operations of the various parts of the device, so that both
drums or motors may be wound together and will run for the same length of
time.
The auxiliary drum 39 which is illustrated in detail in Figures 13, 14 and 15,
is preferably mounted in substantially the same manner as the main drum and is
provided with the usual peripheral gear 54 which is engaged by a suitable pawl
(not shown) to prevent a backward movement thereof. Co-operating with the
winding gear 54* of this drum is a winding pinion 55 carried by a winding
stem 56 which projects to the outside of the casing and may be wound by a
suitable handle 57. The gear 54 meshes with a gear 58 which forms part of a
train of gear (Figure 6) which communicates motion to a governor 59 which is
preferably constructed in the manner illustrated in Figures 9 and 10.
auxiliary drum is provided with a series of cams which may be cast integral with
the drum and the purpose of which is to bring about the auxiliary movement of
the parts. Thus one half of the cam 60 effects a movement of the carriage and
its locking mechanism, one half of the cam 61 causes a note disk to be fed to
operative position and to be returned to the carriage, and one of the cams 62
operates the note disk pivot and presser bar.
The
I will describe the mechanism operated by the auxiliary drum in the order in
which the operations take place:
The note disk carriage which first receives movement, is in the present case
constructed with a view to positiveness of action, simplicity of construction, ready
removal from the instrument, and to facilitate the mounting and dismounting
of the parts.
The note disk carriage and its co-operating mechanism is best illustrated in
Figures 3, 4, 5, and 11, in which figures it will be observed that cross bars 63
are removably connected to side bars 64 as by means of set screws 65. A
suitable number of supporting bars 66 extend across and are supported by the
cross-bars 63. As shown, one end of each of these bars 66 is provided with a
yoke or forked portion 67 which straddles one of the cross bars 63 and is held
in such position by a set screw 68. The opposite end of each of the bars GG is
supported upon the other cross bar 63. From the upper face of bars 66 project
dividing pieces or rods 69 between which the note disks or sheets 9 are adapted
to be received and prevented from lateral displacement. The bars 66 may
likewise be provided with V-shaped grooves between the rods 69 to receive the
edges of the disks and further aid in maintaining the disks properly
located upon the carriage. Each of the side bars 64 is provided
with wheels 71 and 71 which are adapted to run on suitable rods 72

page_text: forming tracks, that are adapted to be secured to the base of the casing. Passing
under each of these tracks 12 is a yoke 74 removably carried by each of the side
bars 64 and the office of which is to prevent the carriage from being displaced
from the tracks. By forming the rollers 71 with a grooved bearing surface and
the rollers 71 with a plane bearing surface, slight inexactness in mounting is
overcome, since the carriage will accommodate itself to the rails notwithstanding
any inexactness of the relative adjustment of the tracks and carriage.
In order to move the note disk carriage. I provide a rigid arm 75 which extends
from one of the cross bars 63 of the carriage. This arm is provided with a
pin 76 which passes through a slot 77 in an operating lever 78 which is pivoted
at 79 and at its opposite end carries a bowl or roller S0) which operates in an
internal cam groove S1 of a heart-shaped cam 82. This cam is pivoted as
indicated at 83 in Figure 11. and has a gear 84 connected therewith. Meshing
with the gear 84 is a gear 85 which is prevented from moving in a direction
opposite to that of the arrow in Figure S, by a pawl 86.
With the gear 85
meshes a gear 87 which is provided with substantially twice as many teeth as
there are note disks in the carriage and in order to economize space it is provided
with only one half the number of teeth on the gear 85. By arranging the teeth
on the gears 85 and 87 in the manner described, two teeth on the gear 85
mesh between every two teeth on the gear ST. A further reason exists for
arranging the teeth on the gear 87 in the manner described and for providing
the spaces 8 between the teeth, as will hereinafter appear. Connected to the
gear wheel $7 is a pointer 95 (Figure 21) which rotates therewith but is carried
at the outside of the casing and co-operates with an index dial 96 that bears the
numbers of the tunes which are adapted to be played by the disks in the carriage.
A vibrating arm SS (Figure S) is pivoted as indicated at 89 and is provided
with a locking nose 90 which is adapted to be forced into engagement with the
teeth of the gear wheel 85. To the arm SS is connected an arm 91 which carries
a roller at its outer end that is adapted to bear against the edge of the cam 60 on
the drum 39 and is maintained in engagement with said cam by a spring 92 which
is connected at one end to the arm SS and at the other end to a stationary portion
of the instrument. The arm SS likewise carries a pivoted pawl 93 which is under
tension of a spring 94 by which the pawl is maintained in engagement with
the gear S7. The inner face of this pawl is so shaped that it will allow the pawl
to ride over the teeth of the gear wheel S7 when the arm SS moves in an upward
direction, whereas the outer face of the pawl will engage the teeth and transmit
movement to the gear when the arm SS is moved in an opposite direction.
Formed integral with the arm 88 is a wiper arm S8, as clearly indicated in
Figure 7 of the drawings. This wiper arm SS* is provided with a cam face S9*
which is adapted to engage a pin 90 (see Figure S) upon a spring-pressed
pawl 91, which pawl is adapted to engage the teeth of the gear wheel S7 and
lock the parts against movement.
in
It will thus be understood that when the arm 91 is vibrated from the
position illustrated in Figure 5 to that illustrated in Figure 6 by
the Caun 60, the pawl 93 will cause the gear S to be moved
the direction of the arrow and will transmit motion to the gear 85
until the nose 90 on the arm SS is brought into engagement with the gear 85
when the parts will be locked against further movement, leaving the roller on the
end of the arm 91 resting on the semi-circular outside portion 97 of the cam (f).
The movement transmitted to the gear 85 is imparted to the gear S4 and the
cam 82 connected therewith, which effects a movement of the carriage through the
intermediate lever 78, thereby bringing the desired note disk to a position where
it can be engaged by the transporting mechanism.
It will be observed that the locking nose 90 does not operate to lock the
carriage against movement until a full movement has been imparted to the
carriage. For this reason the hand operated pointer might be turned to move
the carriage after the parts had been set into operation and injury to the instru-

page_text: ment might thereby result unless some means were provided to prevent the
carriage from being moved more than one space after the device has been set
into operation to work automatically. The locking pawl 91 is provided for
this purpose. It will be observed that as soon as the arm SS is set into operation,
the pawl 91 will drop into the space between the teeth of the gear wheel 87
and will prevent said wheel from being moved further than the distance to the
next tooth thereof, as represented in Figure 7 of the drawings. The pawl 91*
will remain in this position until the arm SS is raised to the initial position when
the pawl 91 is automatically forced out of the locking position by the cam 89*
on the wiper arm SS*:
I will next describe the transporting mechanism or the means for conveying
the note disk to and from operative position.
From the face of the framing on cach side of the instrument, project brackets 98
to each of which is secured the upper end of a guide rod 99 (Figure 8) the
lower end of each of these rods being secured at the lower end to a suitable
bracket 100 (Figure 3). Upon these rods a pair of note disk transporting arms 101
are adapted to slide. Each of the note disk transporting arms comprises
a bifurcated end 102 which is adapted to receive the edge of a note disk and
the sleeve-like members 103 which are adapted to surround a guide rod 99.
The arms 101 co-operate to grasp a note disk 9 upon opposite sides and to
raise or lower the note disk when the metal bands 104, one of which is
connected to each of the slides, are moved. Each of the bands 104 has
its end secured to a pulley 105. These pulleys 105 are adjustably fixed, as
indicated at 106, upon a rotating shaft 107, which likewise carries a single fixed
pulley 108 which is adjustable by means of the set screw 110 and to which is
secured one end of a metallic band 109. The other end of this band is connected
to a pulley 111 which is fixed upon a shaft 112 that carries a pinion 113 with
which a segmental rack 114 meshes. This rack 114 is pivoted as indicated at
115, and a depending arm or extension 116 of said rack projects beyond the pivot
and carries a roller 117 which is adapted to bear upon the edge of the cam 61.
It will be observed from Figure 5 that the bands 104 and 109 pass around their
respective pulleys in opposite directions so that when the parts are in the position
illustrated in Figures 5, 5, and the auxiliary drum 39 is rotated in the direction
of the arrow, the roller will ride on the cam from Ri point near
the centre of rotation of the drum to રા point near its periphery.
This movement of the cam 61 causes the segmental rack 114 to be shifted from
the position illustrated in Figure 5 to the position indicated in Figure 6, and
motion is transmitted to the pulley 111, the band 109, the pulleys 105, the
bands 104 and the transporting arms 101, to raise the note disk into operative
position, which is indicated in Figure 6. At this time the roller 117 bears upon
one of the two waits or flat portions 118 of the cam 61. When the cami is
again moved, it will cause the roller 117 to move to the opposite side thereof
and to attain the same relative position that it stood in when the instrument
started to operate. This movement of the roller 117 on the opposite side of the
cam lowers the note disk to its place on the carriage and the weight of the
It will
arms 101 tends to maintain the roller in engagement with the cam.
thus be observed that a half revolution of the auxiliary drum 39 causes the note
disk to be moved to the operative position and to be lowered again.
After the note disk has been moved to the operative position it is necessary
to move the pivot 13 and the presser bar 14, and I will now describe the means
for effecting these movements.
The presser bar 14 is connected at each end to a bar 119 which passes through
the bed-plate 6 and is provided with an adjustable collar 120, while the springs 121
surrounding the rods 119 at the outer ends, tend to normally maintain the presser
bar 14 in the released position shown in Figure 5. Near each end of the rock
shaft 37 is adjustably secured an arm 122 which is bifurcated at its upper end
so as to straddle the rod 119 and bear upon the rear face of the sleeve 120. The

page_text: rock shaft 37 likewise has adjustably connected therewith an arm 123 to which is
connected a link 124 that is likewise pivotally connected to the note disk pivot 13,
which, as before explained, is adapted to reciprocate in the sleeve-like extension 23
of the shield 24. The rock shaft also has adjustably secured thereto an arm 125
that carries a roller 126 which stands in the path of the cam 62 on the auxiliary
drum 39.
It will thus be observed that after the note disk has been conveyed to operative
position in the instrument, the drum 39 attains the position illustrated in
Figure 6, when one of the cams 62 is brought into contact with the roller 126
(as shown in dotted lines in this figure) and the arm 125 is shifted. This shifting
of the arm 125 causes the shaft 37 to be rocked, thereby projecting the pivot 13
through the central hole in the note disk and simultaneously causing the presser
bar to be moved towards the note disk by the action of the arms 122 upon the
collars 120, as indicated in Figure 6. It is obvious that a further movement of
the drum 39 from the position illustrated in Figure 6 will allow the roller 126
to run off the cam and to rest upon one of the plain semi-cylindrical portions 127
of the drum. This action releases presser bar 14 and withdraws the pivot from
the hole in the note disk.
I now come to the mechanism for automatically starting one of the drums
or motors when the other is brought to a state of rest in order to automatically
bring about the various operations or cycle of movements of the device.
This mechanism is illustrated in detail in the diagrammatic perspective view
shown in Figure 1S. In this figure the main and auxiliary drums 38 and 39
respectively, are represented by the dotted circles, of which the circle 128 repre-
sents the cam track on the main drum, whereas the circles 129 and 130 represent
the cam tracks on the auxiliary drum.
A casting 131 is secured to the casting 40, as indicated at 132 in Figure 3.
This casting 131 carries the mechanism for setting one drum into operation when
the other is stopped. Thus, the lever 133 is pivoted on a pin 134 and one end of
this lever is operatively connected to the starting lever 5 by the link 135, while
the other end of the lever 133 is provided with a hook-like projection 136 that
is adapted to hear upon the cam track 130 and is maintained in contact therewith
by a coiled spring 137. Near the end 136 of the lever 133 is connected, by
means of a slot and pin connection 138, the arm 139 of the stop lever 140, which
has an arm 144 that is adapted to extend into the path of the arm 50 carried by
the governor 59 when the parts are in a state of rest. While the starting lever 5
and the levers 133 and 140 are themselves connected to each other, they are dis-
connected from the other parts of the starting and stopping mechanism and operate
independently thereof, but are so timed as to co-operate therewith, as will herein-
after appear.
A second lever 142, which is somewhat similar to the lever 183, is mounted
upon the pin 134 and is connected to a stop lever 143 in the same manner as
is the lever 133. When the auxiliary drum 39 has been released and has made
a partial revolution, the lever 143 is projected to the position indicated in Figure 18
to stop the governor 59, as will hereinafter appear. The upper end of the lever 142
is connected to a crank arm 145 carried by a rock shaft 146, to the opposite end
of which is fixed the stop lever 147. The stop lever 147 is provided at one end
with a finger 148 which is adapted to hear upon the cam track 128 of the main
drum, and the other end 149 of this lever is adapted to project into the path of
the arm 50 of the governor 49 of the main drum. The lever 142 is likewise
provided with a cam face 150 against which an anti-friction roller 151, carried
by a spring-pressed pin 152, is adapted to bear. The pin 152 is moved laterally
with and adapted to move longitudinally in a sleeve 153 which is pivoted to
the casting 131. A spring 154 is contained within the sleeve 153 and is adapted
to bear upon the pin 152 and tends to maintain the same in the projected position.
The sleeve 153 is connected by a pin and slot connection 155, to the arm 156
of a three-arm lever 157 which is pivoted to the pin 134. The arm 158 of this

page_text: lever 157 projects into the path of the pins 53 on the main drum, whereas the
arm 159 projects into the path of the pins 160 on the auxiliary drum and
motion which is thereby imparted to either of said arms is trans-
mitted to the pivoted sleeve 153 to shift it together with the bearing pin 152
to either side of the pin 134 which constitutes the pivot of the lever 142.
".
Now, in order, to provide hand operated means for imparting movement to
the motor controlling mechanism above described, to start the instrument, a
shaft. 161 is journalled at one end in the casting 131 and extends at the opposite
end to the outside of the casing where it is provided with an operating arm 162
(Figures 2 and 3) which co-operates with a scale or index 163 bearing three
points or indications. The first designates the "stopping point," the second the
starting point" and the third the repeating point." The inner end of the
shaft 161 carries a hook or catch 164 and an eccentric pin 165 upon which
the upper end of the lever 133 bears. When the operating arm 102 is upon the
stopping point" the parts are in substantially the position indicated in Figure 18,
whereas when the operating arm has been moved further to the "starting point,"
the catch will be rotated substantially to the line a, Figure 18, when it will be
observed that the pin 165 has raised the upper end of the lever 133 to start the
instrument. It will likewise be observed that this movement of the hand
operating lever in no way affects the operation of the automatic or coin controlled
lever 5. When the operating arm is at the "repeating point" the catch 164
will have been moved far enough to engage the pin 165* which connects the
lever 142 and the crank arm 145, thereby allowing the main drum to operate
until such time as the operating arm is moved to the "stopping point" or the
instrument runs down, and will at the same time maintain the drum 49 out of
action, as will hereinafter more clearly appear.
When the instrument is to be operated by the coin-controlled mechanism, a coin
of a predetermined size and value is inserted in the coin receiving opening and
after having passed through a suitable coin testing device (not shown) is conveyed
to the coin pan 4 and the weight of the coin depresses the outer end of the lever 5,
thereby raising the upper end of the lever 133. This movement imparted to
the lever 133 will withdraw the end 136 thereof from the depression 166 of
the cam track 130 and will, on account of its connection with the lever 140,
cause the hook-like end 144 of said lever to be withdrawn from the path of the
arm 50 of the governor 59 and the instrument has been started.
Now in order that the operation of the motor controlling mechanism may be
fully understood, I will take up the movement of the parts from the point where
the governor 59 is released and will describe the operation of the controlling
mechanism. Releasing the governor 59 allows the drum 39 to make a partial
revolution, say from the line b to the line e in Figure 18, when the end 136 of
the lever 13 will still be retained upon the high portion of cam track 130, but
the corresponding end of the lever 142 will drop into the depression 107 of the
cam track 129. This movement of the lever 142 will cause the stop lever 143,
with which it is connected, to be projected into the path of the arm 50 of the
governor 59 and will at the same time cause the arm 148 of the lever 147 to be with-
drawn from the depression 168 in the cam track 128 of the main drum, by reason
As the upper
of the crank arm connection 145 between the levers 147 and 142.
end of the lever 147 is withdrawn from the depression 16S, the lower end 149 of
said lever will be withdrawn from the path of the arm of the governor 49 of
the main drum, thereby allowing said drum to make a half revolution. In
making the half revolution, one of the pins 53 on the main drum contacts with
the arm 158 of the lever 157, thereby causing the pivoted sleeve 153 to be vibrated
to the opposite side of the pin 134. This movement of the sleeve will cause the
pressure of the spring 154 to be exerted upon the lever 142 on the opposite side
of its pivot 134 from that upon which the spring pressed pin 152 is shown to
bear in Figure 18. It will thus be seen that by reason of the fact that pressure
is now exerted upon the upper end of the lever 142, the end 148 of the lever 147

page_text: will be forced into the depression 169 of the main druin, when it has completed
one half a revolution, thereby carrying the lower end 149 of said lever into the
-path of the arm 50.on the governor 49 and will stop it from revolving.
It will be remembered that during this half revolution of the main drum, the
auxiliary drum has been maintained against movement by the lever 143. Now
at ibe.time when the lever 147 is moved to stop the governor of the main drum,
the auxiliary drum' is simultaneously released by reason of the crank arm (145)
connection between the' levers 142 and 147. Thus when the upper end 148 of
the lever 147 is forced into the depression 169 in the manner specified, a movement
will likewise be transmitted to the upper end of the lever 142, thereby withdraw-
ing its lower end from the depression 167 in the auxiliary drum. This movement
of the lever 142' will, by reason of its connection with the stop lever 143, cause
Said stop lever to be withdrawn from the path of the arm 50 of the governor 59
when the ausiliary drunii is free to rotate in the direction of the arrow a distance
Corresponding substantially to the distance between the lines in Figure 18.
"The rotation of the drum 39 from the lines' c tó d will bring one of the pins 160
into contact with the arm 159 of the lever 157 and will cause all the parts of the
shifting nicchanism to be moved back into the initial position represented in
Figure 18 and spring pressure is again exerted by the pin 152 upon the lower'end
of the lever 142.
It will be remembered that the stop lever 140 and the parts connected there-
with operate independently of the shifting mechanism so that when the drum com-
pletes its movement from the lines' to d, the depression 170 in the cam track 129
will have been brought into tlie path of the end 136 of the lever 133 and said
end will have been forced into the depression. The movement thus given to
the lever 133 will cause the stop lever 140, which is connected therewith, to be.
projected into the path of the arm of the governor 59, when the entire apparatus
will be brought to rest.
From the foregoing description it will be seen that for cach half revolution of
both drums a complete movement of the various parts is brought about and that
during a further movement of the main drum from the notch 169 to the notch 168
the operation hereinbefore described will be repeated, and that this is likewise
true when the auxiliary drum is further rotated from the line d to the line b.
I have made reference heretofore to the coin pan 4 and starting lever 5, and
while the particular construction of starting lever shown in the annexed drawings
forms no part of my present invention and any suitable device may be used in
its stead, I will describe its construction and operation, that a clearer under-
standing of the operation of the entire apparatus may be had.
The coin pan 4 preferably has a perforation in its bottom that is slightly
less in diameter than the diameter of the coin intended to be used, so that in
case a false coin or one which is smaller in diameter than the size of the coin
intended to be used, is deposited in the pan, it will drop through the bottom and
will not weigh down the lever 5. This pan 4 is secured to a rod 171 which is
pivoted to turn upon the starting lever 5 and is normally maintained in the
position illustrated in Figure 3 by a coiled spring 172. This rod 171 is provided
at its rear end with a right angled extension 173 which projects into the path of
the pins 53 (Figure 8) on the main drum, or other suitable pins may be provided
therefor. By this arrangement it will be seen that when the main drum brings
one of the pins in contact with the extension 173 the rod 171 will be turned
against the tension of its spring which will cause the coin pan 4 to be turned
over to discharge any coin which may have been caught therein.
When a proper
coin has depressed the outer end of the starting lever 5, the rear end 174 will be
elevated and by reason of its connection with the link 185, will cause the lever 183
(Figure 18) to be raised to set the device in operation.
Having described a construction embodying my invention and the operation
of the individual parts thereof, I will now briefly describe the operation of the
entire device.

page_text: We will suppose that the parts are in a state of rest and that the operation
of the device is controlled by a coin and that the first disk in the carriage is
to be played.
The coin is first inserted in the coin slot in the casing and is conveyed to
the coin tray. The tray end of the starting lever will thus be depressed and the
auxiliary drum started in the manner before described. The auxiliary drum
having been released at the line b (Figure 18) will revolve a distance correspond-
ing to the distance between the lines bc when the auxiliary drum will be stopped
and the main drum started in the manner which has been described. This move-
ment of the auxiliary drum from the lines b to c, which I term the first move-
ment, first causes the cam 60 to move the upper end of the arm 91 outward, thereby
rotating the gear 87 the distance between two teeth, by means of the pawl 93.
When these parts have been brought to the end of their movement, the nose 90
is forced between the teeth of the gear S5, thereby locking the parts against
further movement. The movement which was given to the gear 87 was trans-
mitted to the gear 85, from the gear 85 to the gear 84 and to the heart-shaped
cam 82 which moved the lever 78 by which the carriage was shifted to bring the
first note disk in the carriage to a position where it can be conveyed to operative.
position in the instrument. The movement given to the gear 87 caused the
pointer 95 which is connected therewith and which is carried at the outside of:
the casing, to be moved to the numeral 1 on the dial 96, thereby indicating that
the first tune is to be played, and reference to an index which is preferably:
carried by the casing, but has not been shown, will disclose the name of the tune.
After the note disk carriage has been locked against movement in the manner
stated, the cam 61 will be brought into action to cause the depending arm 116
of the segmental rack 114 to be moved from the position illustrated in Figure 5
to that illustrated in Figure 6, which will result in the transporting arms 101.
being raised in the manner which has been heretofore described, to convey the
first note disk to operative position.
After the note disk has been raised, one of the cams 62 will be brought into
contact with the roller 126, to rock the rock shaft 37 and thereby cause the
pivot 13 to be projected through the central hole in the disk and at the same.
time the protector bar 32 (Figure 19) will be moved to the dotted line position;
and the presser bar 14 will be moved inwards to clamp the note disk in position
and to cause the rack thereon to be brought into engagement with the driving
wheel 12. The parts will be maintained in this position by the roller 126 being
maintained on the highest portion of the cam 62, as indicated in dotted lines
in Figure 6..
It will be observed that all of these movements of the parts have been pro-
duced while the drum has been travelling the distance between the lines b and c,
or during what I have termed the first movement.
When the line is reached. the movements above described have taken
place, and the lever 142 (Figure 18) will be at once forced into the depression 167,
which will result in the lever 143 being operated to stop the governor 59 and the
lever 149 will be simultaneously withdrawn from the path of the governor 49,
thereby freeing the main drum which will rotate the driving wheel 12 to operate
the note disk. When the note disk has made a complete revolution, the main
drum will have made a half revolution thereby bringing the depression 169 to a
point where the arm 148 of the lever 147 may be forced therein. The move-
ment thus given to the lever 147 will cause the governor of the main drum to be
stopped and the auxiliary drum to be again released. Thus the second move-
ment has been completed and the third movement started.
The third movement corresponds to the movement of the auxiliary drum
between the lines c and d (Figure 1S) which first causes a movement of the cam 62
on the top of which the roller 126 has been resting, thereby releasing the
arms 125 and allowing the clamping bar, note disk pivot and protector bar to;
simultaneously resume their normal positions. As soon as these parts have been;

page_text: moved in the manner described, the cam 61 allows the transporting fingers 101
to be lowered together with the note disk, and the note disk will in this manner
be deposited in its place in the carriage. At the same instant an opening in
the cam 60 will be brought opposite to the roller carried by the arm 91 when
the roller will be forced into said opening by reason of the connection of the
spring 92 with the arm. 88. This movement of the armi 91 will cause the lock-
ing nose 90 to be withdrawn from the teeth of the gear 85, when the carriage is
free to be moved by the operating lever 95 so that any desired tune disk in the
carriage may be brought into the path of the transporting arms 101 instead of
having the carriage automatically fed to a position where the next succeeding
note disk will be brought into the path of the arms 101.
Where the instrument is intended to be started by hand, the operation is
the same except that the coin tray and slot are dispensed with and the starting'
lever is operated by operating arm 162 in the manner herein before described.
It will be noted in this connection that when the operating cam 162 is turned to
the point "repeat"the catch 164 will engage the pin 165 and will prevent the
stop lever 149 from stopping the governor of the main drum and will render
the lever 157 ineffective to perform its usual function. However, the lower end
of the lever 142 will be forced into the depression 167 when it is reached and
after the auxiliary drum, which has been released by the pin 165 acting on the
lever 133, has moved sufficiently far to bring about the raising of the note disk.
and the clamping of it in position.
It will thus be seen that when the operating arm 162 has been moved to the
repeating point," a disk will be moved up into operative position, will be
properly clamped and the main drum set in operation and that after the note
disk has made a complete revolution it will at once continue to make another
without the necessity of conveying the note disk back to the carriage and again
raising it to the operative position.
The present instrument is intended to operate successively twelve (12) different
note disks of a diameter of twenty-seven inches, though obviously the instru-
ment may be arranged for any suitable number of disks. For this reason the gear
wheel 87 has twenty-two teeth and the dial 96 has a corresponding number of
numerals or indications arranged successively in a circle, as follows: 1, 2, 3, 4, 5.
6, 7, 8, 9, 10, 11, 12, 11, 10, 9, S, 7, 6, 5, 4, 3, 2. Thus it will be seen that the
operating lever or pointer 95 may be moved successively around the dial from
the numerals to 12, thereby moving the heart-shaped cam 82 from the full line
to the dotted line position in Figure 5, and that from this point the numerals
progress in the inverse order to the numeral 1, when the cani 82 is again in the
full line position, so that after the twelve note disks in the carriage have been
played they may be repeated in the inverse order. This same means allows of
the placing of any desired tune out of its order. Thus, suppose the fourth disk
has just been played and it is desired to play the first disk next.
It is merely
necessary to continue to rotate the pointer in the only direction in which it is
capable of being moved, until it is over the numeral 12, and when the instrument
is started the carriage will be automatically fed one space, thereby bringing the
first note disk into action.
In Figures 22 to 25 of the drawings I have illustrated another form of
mechanism for operating the note disk transporting arm. In the mechanism
herein before described for this purpose, it will be remembered the note disk
transporting arms 101 are elevated by positive force, but drop to the lowermost
position by the weight of the arms and the note disk carried thereby. It some-
times occurs that the arms 101 are liable to buckle on the guide rods 99 and thus
be prevented from reaching the lowermost position. In order to overcome this
defect and to provide against any liability of injury to the instrument, I have
devised the mechanism illustrated in Figures 22 to 25 of the drawings wherein
the arms 101 are positively moved in both directions. Thus, instead of securing
a free end of the bands 104 to the arms 101; as in the construction formerly

page_text: described, I employ in the present construction a number of band-sections for
each arm 10.1. One band-section 200 of the transporting mechanism of each
arm is secured to said arm, as indicated at 201 and extends around a pulley 202
near the lower end of a guide rod 99 and up over a guide roller 203 from whence
the free end of the band-section extends around a pulley 204 to a suitable point,
as indicated at 205, where it is secured. This pulley 204 is secured to a shaft 206
which corresponds to the shaft 107 in the transporting mechanism first described.
Adjacent to each of the pulleys 204 is a pulley 207 fixed to the shaft 206. To
each of these pulleys is secured one end of a band-section 208 which passes
around said pulley in an opposite direction from that of the band-section 200.
The other end of each of these band-sections 208 is secured to a note disk trans-
porting arm 101, as indicated at 109. By these means it will be observed that
a positive motion will be imparted to the note disk transporting arms when the
shaft 206 is rotated in either direction.
Motion is transmitted to this shaft 206 by a pulley 210 which corresponds to
the pulley 108 of the construction first described. One end of a band is secured
to this pulley and the other end of said band is secured to a pulley 212 which has
a pinion 213 connected therewith. Engaging this pulley 218 is a segmental
rack 214 which is pivoted, as indicated at 215, and an extension 216 thereof
carries an anti-friction roller 217. This anti-friction roller 217 is adapted to
co-operate with the cam surfaces by means of which the segmental rack is
oscillated around its pivot in both directions by positive pressure. These cams
are carried by the spring drum 39.
In addition to this mechanism for positively operating the note disk trans-
porting arms, I have illustrated in Figures 22 to 25 of the drawings a mechanism
for positively oscillating the rock-shaft 37 in both directions instead of depending
upon spring pressure to move said rock-shaft and the parts connected
therewith in one direction, as is the case in the first described construction. By
this positive operation of the parts, all liability of the mechanism being stopped
by buckling of the parts is overcome.
On the drum 3 are provided four cams 220, 221, 222 and 223, which take the
220
place of the cams 62 in the construction herein before described. The cams
and 221 are in one circumferential line or transverse plane while the cams 222,
223, are in another. Co-operating with the cams 220, 221, is an anti-friction
roller 224 which is carried on a bracket 225 fixed upon the shaft 37 by a securing
nut 226. Projecting from this bracket 225 is a second anti-friction roller 227
which co-operates with the cams 222 and 223. By these means a positive rock-
ing motion is imparted to the rock-shaft 37 and the parts connected thereto in
both directions. Thus a movement of the drum 39 in the direction of the arrow
from the position represented in Figure 25, will cause the cams to be brought
successively into engagement with their respective anti-friction rollers to rock
the bracket 225 and its shaft and to leave the parts in a position the reverse of
that represented in Figure 25, where it is maintained until again operated by the
cams.
