I, JEAN BILLON-HALLER, of Geneva, in Switzerland, Engineer, do hereby declare
the nature of this invention to be as follows:-
My invention consists of an improved mechanism for musical boxes, especially for
those boxes having an interchangeable pin cylinder and being acted upon by means
of a handle. The purpose is first to secure the cover of the bearings of the cylinder
axis whilst the works are playing, and secondly to cause the axial displacement of
the pin cylinder by means of a very cheap and simple arrangement.
In the accompanying drawings, Fig. 1 is a top view, and Fig. 2 an under side view
of a musical box constructed according to my invention, and provided with an
interchangeable pin cylinder acted upon by a handle. Fig. 3 shews, on an enlarged
scale, the function of lever B, and Fig. 4 the function of the pins M. Fig. 5 is a
side view of lever O intended to effect the changing of the airs by means of
click-wheel q and regulator Q.
In all the figures, similar letters refer to similar pieces.
Underneath the plate A there is placed a lever B which is pivotted to A by means
of a screw b. This lever B is provided with a projection B' which is continuously
pressed against the rim f of the pin cylinder F, by a spring C fixed to the plate A. The
rim of the pin cylinder F is provided with a notch into which the projection B',
of B falls at the very moment the pinless part of the pin cylinder arrives in front of
the comb D, that is to say at the end of each air. As shewn in Fig. 3, the projection B'
is provided with a bevelled part upon which the rim f presses when the cylinder F
revolves in the direction of the arrow, causing the lever B to return into its first
position.
The motion of B is transmitted to a sliding bar E, guided by two screws e fixed
to the plate A. This sliding bar E has two inclined parts E' E', which are placed
underneath the pins M, M, which pass through the bearings J and K of the
cylinder F.
.
The pins M are pressed against the said inclined parts E¹ of E by means of a
spring m, so as to be thrown out of the covers j and k of the bearings J and K

page_text: when the lever E is placed in the position shewn by Fig. 4, or to be pressed
through said covers j and k when the lever E is moved from right to left in the
direction of the arrow. The latter takes place when the lever B is in the position
shewn in full lines in Fig. 2, and the position of pin M shewn in Fig. 4 corresponds
to the position of lever B shewn by dotted lines in Fig. 2. The purpose of this
arrangement is to have the pins M traversing and fixing the covers j and k of the
bearings J and K, so long as the air is playing, and to have them moveable when
the cylinder is in its starting position for the purpose of replacing the cylinder by
another one, in turning the covers j and k in the direction of the arrow shewn in
fig. 1.
The lever B, and spring C, are further intended to exert a lateral pressure against
the cylinder F in the direction of its axis, so as to ensure the cylinder being
continuously pressed against the sliding piece U which bears against the disc
provided with as many catches as there are airs upon the cylinder.
The disc is the well known regulating mechanism of the axial position of the
pin-cylinder used in musical boxes, but in place of having the same affixed to the
cylinder itself I affix it to the fixed bearing R so as to use only one disc Q for several
interchangeable cylinders F. The disc Q is connected to a click-wheel g and may be
turned with a view to change the airs, by means of click-lever O bearing a click P,
with spring v.

Improvements in Musical Boxes.
1, JEAN BILLON-HALLER, of Geneva, in Switzerland, Engineer do hereby declare the
nature of this Invention and in what manner the same to be performed, to be
particularly described and ascertained in and by the following statement, reference
being had to the drawings left with my Provisional Specification, and to the letters
and figures marked thereon, that is to say :-
My invention consists of an improved mechanism for musical boxes, especially
for those having an interchangeable pin-cylinder and acted upon by means of a
handle. The purpose of the invention is first, to secure the cover of the bearings
of the cylinder axis whilst the works are playing, and secondly, to cause the axial
displacement of the pin cylinder by means of a very cheap and simple arrangement.
In the drawings left with my Provisional Specification, Fig. 1 is a top view, and
Fig. 2 an underside view of a musical box constructed according to my Invention
and provided with an interchangeable pin cylinder acted upon by a handle. Fig. 3
shews on an enlarged scale the function of lever B and Fig. 4 the function of the
pins M. Fig. 5 is a side view of the lever O which is intended to effect the changing
of the airs by means of the click wheel and regulator Q.
In all the figures, similar letters refer to similar pieces.
Underneath the plate A is placed a lever B which is pivotted to A by means of a
screw b. This lever B is provided with a projection B' which is continuously pressed
against the rim f of the pin cylinder F, by a spring C fixed to the plate A. This
rim f is provided with a notch f¹ into which the projection B¹ of the lever B falls at the
very moment the pinless part of the pin cylinder arrives in front of the comb D, that is
to say at the end of each air. The projection B', as shewn in Fig. 3, is provided with
a bevelled part upon which the rim presses when the cylinder F revolves in the
direction of the arrow, causing the lever B to return to its first position.
The motion of the lever B is transmitted to a sliding bar E guided by two
screws e fixed to the plate A. This sliding bar E has two inclined parts E¹ E¹
which are placed underneath the pins M M which pass through the bearings J and K
of the cylinder F.
The pins M are pressed against the said inclined parts E', of the sliding bar E,
by means of a spring m so as to be thrown out of the covers ; and k of the
bearings J and K when the lever E is placed in the position shewn in Fig. 4, or
to be pressed through said covers j and k when the lever E is moved from right
to left in the direction of the arrow. The latter takes place when the lever B is in
the position shewn in full lines in Fig. 2, and the position of pin M, shewn in Fig. 4,
corresponds to the position of lever B shown by dotted lines in Fig. 2. The purpose
of this arrangement is to have the pins M traversing and fixing the covers j and k of
the bearings J and K, so long as the air is playing, and to have them moveable when
the cylinder is in its starting position for the purpose of replacing the cylinder
by another one in turning the covers ; and k in the direction of the arrows shewn
in Fig. 1.

page_text: The lever B, and spring C, are further intended to exert a lateral pressure against
the cylinder F in the direction of its axis, so as to ensure the cylinder being con-
tinuously pressed against the sliding piece U which bears against the disc Q provided
with as many catches as there are airs upon one cylinder.
The disc is the well known regulating mechanism of the axial position of the pin
cylinder used in musical boxes, but in place of having the same affixed to the cylinder
itself I affix it to the fixed bearing R so as to use only one disc Q for several
interchangeable cylinders F. The disc Q is connected to a click-wheel q and may be
turned, in view of changing the airs, by means of the click lever O, bearing a click P
with spring v.
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. In musical boxes, the combination of the lever B, having a projection B' and a
spring C, with the rim of the cylinder F having a notch f³, substantially as shewn
and described and for the purpose specified.
2. The combination of the lever B with the sliding bar E and the pins M, sub-
stantially as shewn and described and for the purpose specified.
3. The combination of the spring C, lever B, and cylinder F, with the bearing R
to which is affixed a disc Q with sliding piece U, click wheel q, lever O, click P, and
spring, substantially as shewn and described, and for the purpose specified.
