I OSKAR PAUL LOCHMANN of 17 Langestrasse, Gohlis, near Leipzig in the
Empire of Germany, Manufacturer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:—
In mechanical musical instruments constructed according to the present inven-
tion, a removable sheet of cardboard or other material, carrying projecting pins, or
provided with suitable holes, is inserted in a suspended framing of segmental form,
to which is imparted a rocking motion, whereby vibrating "tongues" or notes are
operated upon and caused to give forth musical tones.
The arrangement of suspended rocking or swinging music plate has the following
advantages over the arrangements of musical apparatus with removable music
hitherto devised.
The flat sheets of music, by being inserted in the suspended framing, take a
curved form corresponding to the radius thereof, and thereby have imparted to
them a tension which effectually prevents the buckling or crumpling of the sheet.
The placing of the music with respect to the "playing" mechanism can be
regulated with the greatest nicety. The changing of the music sheets is also
rendered very simple, as it is only necessary to remove the cover of the instrument,
in order, without further trouble, to withdraw the music from the instrument. The "
sheets or cards also hold themselves fast in position, in consequence of their own
tension, and thus the arrangements otherwise necessary for leading or conducting
the sheets of music, in proper position, to the operating mechanism, can now be
dispensed with.

constructed according to the present invention, and Figure 2 is a side view of the
same. Figure 3 is an end view, showing the apparatus provided with reeds or
pipes in lieu of metal tongues.
G is a swinging segmental frame mounted horizontally in bearings within the
case. Upon the lower or curved surface of this frame is stretched the music

sheet P, provided with pins or projections, or, it may be, slits (see Fig. 3).—D is
a segmental rack plate secured to the frame G.
A is a shaft with a worm at the end thereof (see Fig. 1) engaging with a worm
wheel B. This worm wheel is mounted upon and secured to a sleeve b, which
rotates upon the axle of the toothed wheel C, engaging with the segmental rack D
of the frame G.-b¹ is a disc formed in one with the sleeve b above mentioned and
i is a pin upon the face thereof.
Upon the axle of the toothed wheel C, and attached to the said toothed wheel,
is a disc c, having on its surface a hole i¹, with which the pin i upon the disc b¹
engages, and having upon its periphery a projection f, adapted to coine into contact
with the wedge shaped piece h, for the purpose hereinafter described.
e are a series of star wheels for engaging with, and operating the various
vibrating tongues or notes of the instrument.
The operation of the instrument, in playing, is as follows:-
The
By the turning of the shaft A, either by means of a crank handle, as shown in
the drawing, or by clockwork, the toothed wheel B will be caused to rotate.
toothed wheel C, which is in connection, through the pin i and pin hole ', with
this wheel B during the playing of the instrument, takes into the segmental rack D
secured to the suspended framing G, and moves the latter, together with the sheet
of music carried thereon, in the direction of the arrow, and over the operating
mechanism. The "note pins" now strike against the small star wheels e, and
these latter cause their respective notes, which are situate immediately opposite
them, to give forth their respective sounds.
When the suspended framing has completed its traverse over the series of notes,
the projection f of the disc c, which is in connection with the toothed wheel C,
comes into contact with the wedge-shaped piece h, and the entire swing frame will
be pushed, in the direction of its length, to the extent of the breadth of half a note.
By this endway movement of the swing frame, the connecting pin i escapes from
the hole of the disc c,.and the wheel C becomes disengaged from the driving
wheel B, as also the entire swing frame, together with its sheet of music.
"
The swinging frame G being weighted on one side only, by means of the weight /,
the said frame now falls back until the first " note* pins come back to the star
wheels è, and in this backward motion, the "note pins" pass between the various
notes or sounding tongues.
Through the back motion of the swing frame, the wheel C, with its axle, will
be turned round in a backward direction, until the connecting pin i again comes
opposite the hole -The swing frame, and the sheet music thereon, are then
caused, by the spring H, again to take the correct position with respect 'to the
series of notes, and the pin is caused to engage with the pin hole 2².
Figure 3 shows a modification of the above described musical apparatus, in which
the swinging music sheet is adapted for employment with pipes or reeds. The
sheet music P will be inserted in the swing frame in the same way as before.
The projections on the sheets or cards, when used with pipes or reeds, are in the
form of pins or points and staples.-These points or pins, and staples, then actuate,
as in the ordinary barrel organ, the valve levers's of the various notes.
Instead of a sheet carrying pins and staples, a sheet provided with holes and
slits may be employed if desired.
In Figure 3, the music sheet is represented on the left hand side as provided
with points and staples, and on the right hand side with holes and slits.
7. S
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. A mechanical musical instrument constructed substantially as above described
with reference to the drawings, in which is suspended a detachable sheet of music

page_text: provided with projections such as pins, or staples and pins, or with holes or slits,
for operating the music-producing mechanism of the instrument.
2.. In the musical instrument or apparatus referred to in Claim 1, the automatic
disengaging mechanism, consisting in the combination of disc c, connecting pin i,
projection, and wedge h, which comes into operation at the end of each section of
sheet music, and allows the frame carrying the music sheet to move into its original
position, substantially as set forth.
