COMPLETE SPECIFICATION.
Mechanical Musical Instrument with Changeable Music Discs.
I, EDUARD BRESLAUER, of 7, Goethestrasse, Leipzig, in the German Empire,
Engineer, 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:-
-
According to the present invention it is intended to bring the individual discs
of a supply of music discs into engagement with the driving apparatus by pivot-
ing each of the discs on a special music-disc-bearer or carrier. The music-disc-
bearers should be so adjustably arranged, that each music-disc can be brought
by pushing or by a swinging movement of the music-disc-bearer over the musical
instrument or mechanism and within the sphere of the driving apparatus.
Figure 1 is an elevation, and Figure is a section of such a musical instru-
ment with suspended swinging music-disc-bearers.
Figure 3 shews some of the music-disc-bearers, with music-discs arranged
below.
Figure 4 is an elevation and Figure 5 a longitudinal section, and Figure 6 a
cross section of a musical instrument with moveably seated music-disc-bearers.
Figure 7 illustrates such music-disc-bearers in detail.
The music-disc-bearers A¹ A2 A3 &c. (Figures 1 to 3) consist of simple arms,
which extend beyond the middle of the music-discs, each one being intended
for receiving a music-disc. Each of the music-discs N¹ N2 N3 &c. is pivoted
in its music-disc-bearer so that it can perform a rotary movement on its axis,
whilst its music-disc-bearer remains stationary.
In the form shewn by way of example in Figures 1 and 2, a number of music-
disc-bearers A1 A2 A3 &c. are set in a row on a pin S, and each of them can be
pushed on the pin S and be brought by a swinging movement over the musical
instrument.
In Figures 1 and 2 the music-disc-bearer A with the music-disc N is brought
above the musical instrument and into engagement with the driving apparatus.
In the form illustrated in Figures 1 and 2 the music-disc holder B must be
somewhat raised, in order that the music-disc may be introduced between the
small wheel-holder R and the music-disc holder B. Through the pressing down
of the music-disc holder B, following thereon, the music disc is brought into
engagement with the driving apparatus.
The music discs shewn in the drawings may equally well be provided with
transport-teeth on their outer edges and be arranged for external driving; then
by a swinging movement of the music-disc-bearer the music-disc can be brought
into engagement with the driving apparatus.
Figure 3 shews three music-disc-bearers A¹ A2 A3 and the connection of the
music-discs N1 N2 N3 therewith.
The projecting music teeth have a downward direction and, in order that,
when the music disc is turned they may not push against the music-disc-bearer,
the music-disc is seated at such a distance that it can turn freely.

page_text: In the musical instrument illustrated on Figures 4 to 6 the music-disc-bearers
are moveably seated in the journal or bearing L, so that they can be pushed
towards the musical instrument. The bearing L itself is moveably arranged
on the pins S1 and S2, and each of the music-disc-bearers, with its music disc can
be brought over the musical instrument, as illustrated in the drawing in con-
nection with the music-disc-bearer A2 and its music disc.
Each of the music-disc-bearers, in the form illustrated in Figures 4 to 6 is
provided with a music-disc in a bent position or curved shape, that is, a con-
dition of tension, in order that it may be ready for working at once, when brought
over the impulsion or driving apparatus. Figure 7 is a section through a number
of music-disc-bearers A1 A2 A3 containing music-discs in a position or condition
of tension.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1. Mechanical music instruments with automatically changeable music discs the
distinguishing feature being that each of the music discs N' N2
is rotat-
referred to in Claim 1
ably seated or pivoted in a special music-disc-bearer or carrier A¹ A³
2. A modification of the music-disc-bearers A¹ A.
the distinguishing feature being that each of such bearers carries a music disc
which is rotably seated or pivoted and in a condition of tension
3. A modification of the mechanical musical instrument referred to in Claim 1,
the distinguishing feature being that a number of music-disc-bearers A¹ A².
are arranged near the musical instrument on a pin S and so that they can be either
pushed or turned in such a way that any of them can be brought over the musical
instrument and any of the music-discs N1 N2 . . . . be thereby put into engage-
ment with the driving apparatus.
4. A modification of the mechanical musical instrument, referred to in Claims 1
and 2, the distinguishing feature being that a number of music-disc-bearers A
A2
are movably seated in a special bearing L near to the musical instrument,
this bearing being arranged to move transversely in such a manner that cach
of the bearers can be brought over the musical instrument and each music disc
be thereby placed in engagement with the driving apparatus.
