COMPLETE SPECIFICATION.
Tune-sheet Chest for Automatic Musical Instruments.
I, RUDOLF PETER, of Gramzow, in the Province of Brandenburg in the German
Empire, Masier-joiner, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
The present invention refers to an improved tune-sheet chest for automatic
musical instruments, which possesses the advantage of permitting the respective
piece played by the tune-sheet to be indicated or visible without necessitating
the removal of the tune-sheets. stored in the same chest.
The invention is illustrated in the accompanying drawings in which
Fig. 1 shows a front elevation of the improved tune-slicet chest.
Fig. 2 shows the tune-sheet chest open and its interior construction.
Fig. 3 is a special-elevation of the tune-sheet supporting frame, and
Fig. 4 is a plan of Fig. 3.
The side wall a of the tune-sheet chest is arranged in such a manner that
on opening the door this side-wall likewise opens, so that the door, e and
side wall can be brought into a plane with the rear-wall e. The turning of
the side-wall is attained by means of hinges screwed to the rear wall c of
the tune-sheet chest.
On the right hand side of the rear-wall e are situated two ledges g, movable
on hinges f, which ledges are provided at their other extremities with pins h
fitting info and movable in grooves in the side wall a. On opening the door e
and with it the side wall b, the ledges g will turn in their hinges f in view of
the pins, moving in the guide grooves in the side-wall a; it is obvious that
the pins are prevented by any of the well known means from leaving their
guide grooves. The projecting flange of the ledges g is provided with a number
of vertical holes in such a manner that the holes in the upper ledge g corre-
spond with those in the lower ledge g. These holes serve for the reception
of the tune-sheet supporting frames, which by means of studs are movably
mounted in these holes . The tune-sheet supporting frames are, preferably
constructed in the following manner.
A vertical main-bar q provided at both extremities, with the studs referred
to above is fitted at the lower end with a horizontal bar r of smaller length
than the width of the tune-sheet chest. Two stays s secured to the outer
extremity of the horizontal bar r and to the upper end of the main-bar y so as
to leave a space between, ensure a rigid connection of the two bars. A third
bar p, provided with a vertical groove is fitted to the main-bar and the sup-
porting stays s; it is in addition supported in its position by the stays o
The tune-sheet is inserted into the supporting frame by passing it between
the stays and through the vertical groove in the bar p, the length of which
is so arranged that it will reliably support the tune-sheet, the stays s and o
The tune-sheets are
preventing its lower portion from gliding off the bar r.
so inserted into their frames that the title of the piece the respective tune-sheet

page_text: will produce is facing the front of the tune-sheet chest when the latter is closed,
thereby attaining an easy inspection of the various, tune-sheets by turning aside
the various frames, after the tune-sheet chest has been opened.
In closing the tune-sheet chest the various supporting frames arrange them-
selves into proper position to permit an unimpeded closing of the box; when
opening the box they will be brought into position which makes an inspection
of the various tune-sheets easy, as illustrated in Fig. 2.1
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/ An improved tune-sheet chest for automatic musical instruments having
one of its side-walls movable outwards with the door, in combination with ledges
for holding the tune-sheet supporting frames, substantially as set forth with
reference to the accompanying drawings.
2/ In combination with a tune-sheet chest for automatic musical instruments
of the kind described a tune sheet supporting frame, rotatable by means of
studs in holes in the ledges, composed essentially of a triangular structure,
the hypothenuse being formed by a pair of stays s with a space between to
permit the passage of the tune-cheet, the latter being supported in a vertical
groove in the horizontal bar p, substantially as described with reference to the
accompanying drawings.
3/ The tune-sheet chest for automatic musical instruments with rotatabla
tune-sheet supporting frames of the kind referred to, having parts arranged,
constructed, and adapted to operate, as described with reference to the accom-
panying drawings.
