COMPLETE SPECIFICATION.
Improvements in Winding Mechanism for Mechanical Musical™
Instruments.
F
We, FRIEDRICH ERNST MALKE and FRIEDRICH HERMANN OBERLÄNDER,
both of Leipsic-Gohlis, in the Empire of Germany Manufacturers, do hereby
declare the nature of our invention and in what manner the same is to be-
performed to be particularly described and ascertained in and by the following
statement:-
The devices for winding up the clockworks of mechanical musical instruments
hitherto employed consist mainly of complicated arrangements which are as a rule
very expensive.
The object of the present invention is to effect the winding up of mechanical
musical instruments directly, i.e. without the aid of intermediate mechanism.
And in order to render the present Specification more easily intelligible
reference is had to the accompanying drawings in which similar letters of
reference denote similar parts throughout the several views :-
Fig. 1 is a side elevation of one form of carrying out the invention,
Fig. 2 is a plan of Figure 1,
Fig. 3 is a modification of the device in side elevation,
Fig. 4 a plan of Figure 3,
Fig. 5 is a further modification and
Fig. 6 a still further modification.
Figs. 7 and 8 being plans respectively of Figures 5 and 6.
Fig. 9 is a side elevation of driving gear for winding up the drum of the main
spring and
Fig. 10 is a plan of Figure 9.
According to Figures 1 and 2 of the drawings, the drum a enclosing the spring f
is mounted on the spindle a* and provided with a series of holes 6 in which the pins
or sprockets c of the wheel d mounted on the spindle e engage. The latter spindle
is turned or wound up by means of a key in the usual manner and turns the drum a
thus winding up the spring in the well known manner.
In Figures 3 and 4 the sprockets are arranged on the drum a and the orifices on
the wheel d.
According to Figure 5 the bottom of the drum is provided with orifices into
which the sprockets c of the wheel d mounted on a horizontal shaft e engage..
Obviously by turning the shaft e the drum a will be wound up.
In Figure 6 the same arrangement as in Figure 5 is shown with the distinction
that in this case the sprockets are arranged on the bottom of the drum a and the
orifices on the wheel d.
In Figures 9 and 10 the.drum a is provided with an ordinary gear wheel 61
engaging in a pinion b on the shaft e, so that by turning the shaft e the drum a is
revolved and the spring wound up.
In all the cases previously described the casing of the main spring is rotated by
means of the revolution of the driving shaft direct, so that no intermediate
mechanism is necessary to effect this result. Many advantages accrue from this
construction not the least of which being that clockworks constructed according
to the present invention are considerably cheaper to make than those hitherto
known.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
A device for rotating or winding up the spring casings of mechanical musical
works directly consisting in
1. The arrangement of orifices in the spring casing and teeth on the driving gear
or vice versa substantially as described.
2. The arrangement of orifices in the bottom of the spring drum and teeth in the
driving gear or vice versa substantially as described.
3. The arrangement of a gear wheel on the drum to correspond with a pinion on
the winding shaft substantially as described.
