page_text: I, WILLIAM HENRY HOSCHкE, of 187, Park Place, Brooklin, New York, United
States of America, Manufacturer, do hereby declare the nature of this invention to be
as follows:
The invention relates to a musical box in which a perforated music disc is employed,
the said disc being so arranged as to produce the rotation of star-wheels the teeth of
which are intended to act upon one or several combs.
The invention is illustrated in the accompanying drawings, in which,
Figure 1 is a transverse section of a portion of a musical box constructed in accord-
ance with the present invention.
Figure 2 is a transverse section showing the side facing the star wheel illustrated
in Figure 1 when a full portion of the perforated sheet is placed above the star
wheel.
Figure 3 is a section similar to that of Figure 2, showing the lever engaged in an
opening of the perforated sheet.
Figure 4 is a section similar to that of Figure 2, showing the parts in the position
they occupy when the lever has left the opening of the perforated sheet and the said
sheet in the act of operating the star wheel.
Figure 5 illustrates the acting-lever of the setting ruler for the star wheels.
Figure 6 shows in elevation the fixing and stopping device acted upon by the
perforated sheet.
Figure 7 is a section through x-y of Figure 6, looking from left to right.
Figure 8 is a similar section looking from right to left.
Figure 9 is a plan of the device illustrated in Figure 6, and
Figures 10 and 11 illustrate the fly-regulator open and shut.
Similar letters of reference indicate corresponding parts in all the Figures of the
drawings.
A and B are combs, C is a star-wheel intended to act upon the said combs and
D is a perforated sheet rotated by means of any suitable motor and suitably arranged
for rotating the star-wheels, the latter being arranged on a spindle E on which they
are free to rotate.
Adjacent to one of the faces of each star there is placed a damper arm F engaged
on the spindle E and a lever G pivoted on a spindle H. Each damper arm Fis
provided with spring claws f bearing with smooth friction against the front-side of
the star-wheel and a projection f¹ engaged in an opening g of the lever G.
The arm Falso carries an arm 2 provided with a damper ft of cloth or any other
suitable material and the lever G carries an arm gl also provided with a similar
damper 9. The said arm g¹ is provided with an inclined plane g² intended to move
the star, and a spring I tends to lift the lever G and to press its conical head against
the underface of the perforated sheet D.

page_text: As long as the headpart of the lever G is in contact with a full portion of the
sheet D, the latter maintains the said lever G in the position shown in Figure 2 in
which the damper gx fixed on its arm g¹ is out of reach of the comb B and in which
the projection f¹ of the damper arm F is prevented from rising so that the damper f*
fixed on the arm fremains a distance from the comb A.
When an opening in the perforated sheet come opposite the conical head of the
lever G, the oscillating movement of this lever around the spindle H while engaging
into the said opening under the impulse of the spring I, causes its opening g to assume
the position shown in Figure 3, and during this movement the edge of the said
opening acts like an inclined plane against the projection f¹ of the damper arm F
and causes the latter to oscillate and bring the damper into contact with the combs.
At same time the inclined portion g² of the edge of the arm g' acts upon the tooth c¹
of the star wheel C arranged in proximity thereto, thus causing the tooth c² of the
said star-wheel to be placed, in, a suitable position for being rotated by the edge of the
opening of the perforated sheet, as shown in Figure 4. Thus the rotation of
the perforated sheet causes the rotation of one tooth of the star wheel C of which two
other teeth cause the sounding of one of the prongs of each of the combs A and B.
After this, the several parts of the device return to the position indicated in
Figure 2.

The device illustrated in Figure 5 is intended to set the star-wheels C, while the
perforated sheet is taken off in order to be replaced by another. The setting ruler K
pivoted at is acted upon by means of a spring not shown in the drawing, in order
to bring back all the star-wheels C into the position in which, the teeth of these latter
are all placed in line. The lever L is pivoted at I and acted upon on the one hand
by means of a spring which tends to raise it and on the other hand by means of a
projection M of the usual radial arm which presses the perforated sheet against the
star-wheels. When the arm N Figure 6 is turned in order to permit the exchange of
the perforated sheet, the setting ruler K is placed in the position shown in full lines
in Figure 5, the lever L. being lifted. But when the radial arm is brought back on
the perforated sheet, its projection M acts upon an inclined plane forming the point
of the lever Land lowering this latter, the beak of which then presses on the heel
of the setting ruler K and raises it, so as to liberate the star wheels C.
In order to prevent the disengagement. of the usual pressure-arın N which main-
tains the perforated sheet supported against the central bearing O, while the musical
box is playing, the latter is combined with a stopping device represented in the
Figures 6, 7, 8 and 9.
This device is combined with the usual stopping-lever P acted upon by means of
a hand-lever P₁ pivoted at 21 to the plate and intended to stop the fly-wheel-
regulator T of the mechanism, separately represented in the Figures 10 and 11. A
shaft O fixed in the bearings q' and q under the plate, carries an arm 0¹ intended to
be moved by the arm p of the lever P, and an arm 02 engaging the spindle R, which
traverses the plate and the central bearing O of the perforated sheet Z.
The excentric spindle R is lodged in a longitudinal recess of the pivot S around which
the perforated sheet turns and a spring tends to lift the spindle R into a corres-
ponding opening of the plate N¹ of the pressure-arm N. The latter can therefore
only be turned in the direction of the arrow shown in Figure 9, in order to liberate
the perforated sheet, when the spindle R is detained towards the bottom, that is to
say, when the levers Q and Q² are displaced in the direction of the arrows 3 of
Figures 7 and 8. As will be seen in Figure 7 this oscillation is automatically pro-
duced by the spring V, as soon as the lever H is disengaged from the lever Q¹.
Figure 7 illustrates the said lever H in the position, in which it bears with its
heel u against the plate, this only taking place when the arm U is not pressed down
by the perforated sheet Z. As soon as a full portion of this sheet Z presses the long
arm of the lever U downwards in the direction of the arrow 4, (Figure 7) the lever ()¹
oscillates in the direction shown by the arrows 5. The lever Pis then free to oscillate
in the direction of the arrows 7, its armn p being no longer detained by the arm Q
and in consequence the piece of music may be played by moving the hand lever Pi.

page_text: The oscillation of the lever Q¹ in the direction of the arrows 5 causes at the same
time the oscillation of the arm Q2 in the opposite direction to that of the arrow 3,
by reason of which the excentric spindle R is again engaged into the head N¹ of the
arm N.
The perforated sheet Z is provided with a special stopping-opening or perforation
intended to be engaged by the extremity of the lever U, as shown in Figure 7, and
if the hand lever P¹ is carefully placed on "stop" the lever P will automatically cause
the stopping of the regulator T as soon as the lever U engages the said opening and
consequently, the arm Q¹ oscillating in the direction of the arrow 3 will cause the
lever P to oscillate in the opposite direction to that of the arrow 7.
Owing to this device the perforated sheet effects therefore automatically and all at
once the stopping of the motor and the liberation of the arm N as soon as the tune is
finished.
When the arm N is turned, the perforated sheet may be placed in any position
whatever, without causing the musical box to play, but the arm N can only be turned
when the perforated sheet is in the position for stopping.
Improvements in Musical Boxes..
I, WILLIAM HENRY HOSCHKE, of 187 Park Place, Brooklin, New York, United
States of America, Manufacturer, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
The invention relates to a musical box in which a perforated music disc is employed,
the said disc being so arranged as to produce the rotation of star-wheels the teeth of
which are intended to act upon one or several combs.
The invention is illustrated in the drawings, left with my provisional specification,
and of which,
Figure 1 is a transverse section of a portion of a musical box constructed in
accordance with the present invention.
Figure 2 is a transverse section showing the side facing the star wheel illustrated
in Figure 1 when a full portion of the perforated sheet is placed above the star
wheel.
Figure 3 is a section similar to that of Figure 2, showing the lever engaged in an
opening of the perforated sheet.
Figure 4 is a section similar to that of Figure 2, showing the parts in the position
they occupy when the lever has left the opening of the perforated sheet and the said
sheet in the act of operating the star wheel.
Figure 5 illustrates the acting-lever of the setting ruler for the star wheels.
Figure 6 shows in elevation the fixing and stopping-device acted upon by the
perforated sheet.
Figure 7 is a section through x-y of Figure 6, looking from left to right.
Figure 8 is a similar section looking from right to left.
Figure 9 is a plan of the device illustrated in Figure 6 and
Figures 10 and 11 illustrate the fly-regulator open and shut.
Similar letters of reference indicate corresponding parts in all the Figures of the
drawings.

page_text: A and B are combs, C is a star-wheel intended to act upon the said combs and D
is a perforated sheet rotated by means of any suitable motor and suitably arranged
for rotating the star-wheels, the latter being arranged on a spindle E on which they
are free to rotate.
Adjacent to one of the faces of each star there is placed a damper arm F
engaged on the spindle E and a lever G pivoted on a spindle H. Each damper
arm F is provided with spring claws f bearing with smooth friction against the
front-side of the star-wheel and a projection f¹ engaged in an opening g of the
lever G.
The arm F also carries an arm provided with a damper f+ of cloth or any
other suitable material and the lever G carries an arm g¹ also provided with a similar
damper. The said arm g¹ is provided with an inclined plane g² intended to move the
star, and a spring I tends to lift the lever G and to press its inclined head against
the under face of the perforated sheet D.
As long as the head part of the lever G, is in contact with a full portion of the
sheet D, the latter maintains the said lever G in the position shown in Figure 2 in
whichthe damper g+ fixed on its arm g¹ is out of reach of the comb B and in which
the projection f¹ of the damper arm F is prevented from rising so that the damper f+
fixed on the arm f2 remains a distance from the comb A.
When an opening in the perforated sheet comes opposite the inclined head of the
lever G, the oscillating movement of this lever around the spindle H while
engaging into the said opening under the impulse of the spring I, causes its
opening g to assume the position shown in Figure 3, and during this movement the
edge of the said opening acts like an inclined plane against the projection of the
damper arm F and causes the latter to oscillate and bring the damper into contact
with the comb. At the same time the inclined portion g² of the edge of the arm gl
acts upon the tooth c¹ of the star wheel C arranged in proximity thereto, thus
causing a feeble rotative movement of the star wheel, which movement causes the
tooth c² of the said star wheel to be placed within reach of the edge of the opening of
the perforated sheet, that is to say in a suitable position for being carried forward by
the said edge of the opening of the perforated sheet as shown in Figure 4. Thus the
rotation of the perforated sheet causes the rotation of one tooth of the star
wheel C of which two other teeth cause the sounding of one of the prongs of each
of the combs A and B. After this, the several parts of the device return to the
position indicated in Figure 2.
The device illustrated in Figure 5 is intended to set the star-wheels C, while the
perforated sheet is taken off in order to be replaced by another. The setting ruler K
is formed of a bar K the two ends of which are pivoted at k to suitable bearings, and
is intended to bring back all the star-wheels C into the position in which the teeth of
these latter are all placed in line. A suitable spring, not shown, causes the said
bar K to assume normally the position shown in full lines in Figure 5 and a lever L
is provided to cause the said bar K to assume the position shown by dotted lines in
Figure 5, whenever the said lever L is depressed by a full portion of the perforated
sheet D. The lever L is pivoted at and acted upon on the one hand by means of a
spring which tends to raise it and on the other hand by means of a projection M
of the usual radial arm which presses the perforated sheet against the star-wheels or
by a full portion of the said perforated sheet itself acting upon the top of the lever L.
When the arm N Figure 6 is turned in order to permit the exchange of the
perforated sheet, the setting ruler K is placed in the position shown in full line in
Figure 5, the lever L being lifted. But when the radial arm is brought back on the
perforated sheet, its projection M acts upon an inclined plane forming the point of
the lever L and lowering this latter, the beak 12 of which then presses on the heel
of the setting ruler K and raises it, so as to liberate the star wheels d.
In order to prevent the disengagement of the usual pressure-arm N which
.maintains the perforated sheet supported against the central bearing O, while the
musical box is playing, the latter is combined with a stopping device represented in
the Figures 6, 7, 8 and 9.

page_text: This device is combined with the usual stopping-lever P acted upon by means of
a hand-lever P¹ pivoted at p¹ to the plate and intended to stop the fly-wheel-
regulator T of the mechanisın, separately represented in the Figures 10 and 11. A
shaft Q fixed in the bearings q¹ and q² under the plate, carries an arın Q¹ intended to
be moved by the urin p of the lever P, and an arm Q2 engaging the spindle R which
traverses the plate and the central bearing ( of the perforated sheet Z.
The eccentric-spindle R is lodged in a longitudinal recess of the pivot S around
which the perforated sheet turns and a spring r tends to lift the spindle R into a
corresponding opening of the plate N¹ of the pressure-arm N. The latter can there-
fore only be turned in the direction of the arrow shown in Figure 9, in order to
liberate the perforated sheet, when the spindle R is detained towards the bottom,
that is to say, when the levers Q¹ and Q are displaced in the direction of the arrows 3
of Figures 7 and 8. As will be seen, in Figure 7 this oscillation is automatically
produced by the spring V, as soon as the lever U is disengaged from the lever Q¹.
Figure 7 illustrates the said lever U in the position, in which position it bears with
its heel u against the bed plate, this only taking place when the arm U is not
pressed down by the perforated sheet Z. As soon as a full portion of this sheet
presses the long arm of the lever U downwards in the direction of the arrow 4,
(Figure 7) the lever Q¹ oscillates in the direction shown by the arrows 5. The
lever P is then free to oscillate in the direction of the arrows 7, its arm p being no
longer detained by the arm Q¹ and in consequence the piece of music may be played
by moving the hand lever P¹.
The oscillation of the lever Q1 in the direction of the arrows 5 causes at the same
time the oscillation of the arm Q2 in the opposite direction to that of the arrow 3,
by reason of which the eccentric spindle R is again engaged into the head N¹ of the
arm N.
The perforated sheet Z is provided with a special stopping-opening or perforation
intended to be engaged by the extremity of the lever U, as shown in Figure 7, and
if the hand-lever P¹ is carefully placed on "stop" the lever P will automatically
cause the stopping of the regulator T as soon as the lever U engages the said opening
and consequently, the arm Q₁ oscillating in the direction of the arrow 3 will cause the
lever P to oscillate in the opposite direction to that of the arrow 7.
Owing to this device the perforated sheet effects therefore automatically and all at
once the stopping of the motor and the liberation of the arm N as soon as the tune
is finished.
When the arm N is turned the perforated sheet may be placed in any position
whatever, without causing the musical box to play, but the arm N can only be
turned when the perforated sheet is in the position for "stopping."
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A musical box with projectionless perforated sheet characterized by the com-
bination of one or more combs with a series of star-wheels each of which is combined
with an adjacent lever intended to engage the openings of the perforated sheet and
which causes the rotation of the corresponding star-wheel and causes at the moment
when it engages the said opening a feeble rotative movement of the said star-wheel,
with the object of bringing one tooth of the latter within reach of the edge of the
opening of the perforated sheet, so as to be carried forward by the latter.
2. In a musical box the combination of the lever adjacent to each star, with a
damper, substantially as described.
3. In a musical box, the combination with each star C of a lever G and of a lever F,
substantially as shown and described.
4. In a musical box a ranging-ruler K in combination with a lever L.
5. In a musical box a stopping-lever, independent of the movement and allowing
the perforated sheet to be placed in any position whatever without causing the
sounding of the tunes before the arrival of the perforated sheet into its position of the

page_text: beginning of the tune owing to the combination of the levers Q and Q fixed to a
shaft Q on the one hand with a spindle R to stop the arm N when the perforated
sheet is in movement and on the other hand with a stopping-lever P, the lever U and
the spring V, in combination with an opening of the perforated sheet disposed so as
to give free passage to the end of the lever U when the box is at "stop," sub-
stantially as described.
