Improvements in Music Sheets for Mechanical Musical Instruments.
I, PAUL EHRLICH Manufacturer of Musical Instruments, residing at Gohlis
near Leipsic in the Kingdom of Prussia German Empire do hereby declare the
nature of this invention to be as follows:-
My invention relates to music sheets of circular or other shape by means of
which tunes are produced in mechanical musical instruments and the object of my
invention is to overcome the objections arising from the wear and tear of the
portions of the said music sheets that work or strike against the sounding
devices of the instruments and at the same time to avoid, as far as possible sharp
points in the sheets in order to facilitate packing.
For this purpose the music sheet is made of sheet metal or other sufficiently
strong material and tongues corresponding to the order of the notes are punched
or cut therein so that they are still adherent to the sheet. By then turning
backwards each tongue, ears are formed which after being fixed in any suitable
manner (for instance by soldering) present solid projections firmly adherent to the
sheet. The tongues may be punched or cut in the sheet in any suitable manner or
shape, for instance triangular or square tongues are punched therein so that two
adjacent tongues turned backwards in opposite directions to overlap each other
form when soldered or otherwise secured together a strong stud presenting no sharp
edges. Or I may punch in the sheet so as to form for each projection a double
tongue one being bent backward to form an ear and the other being bent against
the upturned end of the former so as to secure it in place. Or I may press or
punch the tongues and raise them so that they stand up from the face of the sheet
and fill with any suitable material such as solder, cement or the like, the intervals
between two or more tongues corresponding to the length of the sounds to be
produced by each projection. The sheets so produced can be used for instruments,
the sounding devices of which are tongues reeds pipes or any other devices to
which such sheets can be applied. The invention can of course be employed for
sheets the perforations of which allow the ends of the levers of sounding devices
to move for sounding, and in this case the solid tongues increase the durability of
the edges of the perforations.

Improvements in Music Sheets for Mechanical Musical Instruments.
I PAUL EHRLICH Manufacturer of Musical Instruments residing at Gohlis
near Leipsic in the Kingdom of Saxony German Empire 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 :-
My invention relates to music sheets of circular or other shape by means of
which tunes are produced in mechanical musical instruments and the object of my
invention is to overcome the objections arising from the wear and tear of the

page_text: portions of the said music sheets that work, or strike against, the sounding devices
of the instruments and at the same time to avoid as far as possible sharp points in
the sheets in order to facilitate packing.
For this purpose the music sheet is made of sheet metal or other sufficiently
strong material and tongues corresponding to the order of the notes are punched
or cut therein so that they are still adherent to the sheet. By then turning
backwards each tongue ears are formed which, after being fixed in any suitable
manner (for instance by soldering) present solid projections firmly adherent to the
sheet. The tongues may be punched or cut in the sheet in any suitable manner
or shape, for instance, triangular or square tongues are punched therein so that
two adjacent tongues turned backwards in opposite directions to overlap each
other, form, when soldered or otherwise secured together, a strong stud presenting
no sharp edges. Or I may punch in the sheet so as to form for each projection a
double tongue, one being bent backward to form an ear and the other being bent
against the upturned end of the former so as to secure it in place. Or I may press
or punch the tongues and raise them so that they stand up from the face of the
sheet and fill with any suitable material, such as solder, cement, or the like, the
intervals between two or more tongues corresponding to the length of the sounds
to be produced by each projection. The sheets so produced can be used for
instruments the sounding devices of which are tongues, reeds, pipes, or any other
devices to which such sheets can be applied. The invention can of course be
employed for sheets, the perforations of which allow the ends of the levers of
sounding devices to move for sounding and in this case the solid tongues increase
the durability of the edges of the perforations.
And in order that my said invention may be fully understood I shall now proceed
more particularly to describe the same and for that purpose shall refer to the
several figures on the annexed sheets of drawings the same letters of reference
indicating corresponding parts in all the figures.
Figures 1. 2. 3. 4. 5. 6. 7 and 8 of the accompanying drawings represent some
of the forms of tongues, ears, or projections which may be provided on the music
sheets, and Figure 9 represents one means by which the projections shown in
Figure 8 may be formed on the said sheets.
Referring to Figures 1, 2 and 3 of the drawings projections are formed by
narrow strips a from the sheet as shewn in section and plan in Figure 1 so as to
remain attached thereto at one end and bent out of the plane of the said sheet.
By curling the said strip backwards it forms a firm ear shaped projection bas
shewn at the left hand of Figure 2. The inside of the strip 6 bent over as at the
right hand of Figure 2 may be filled in with solder or other like material and also
if desired strengthened in like manner at the sides so that the whole is firmly
secured to the sheet as shewn at m m in Figure 3 and in either case a strong
projection free from sharp corners is formed.
In the arrangement shewn in Figure 4 triangular or wedge-shaped strips de are
stamped out of the sheet leaving spaces d' e¹ and bent round so that the tapering
sides of the said strips abut against one another and these can then be united
together by soldering or the like. A still stronger projection or ear may be formed
as shewn in Figure 5 in which arrangement rectangular tongues f, 9 are stamped
out of the sheet leaving spaces f¹ 9' and these tongues are bent backwards in
semicircular form so that one overlaps the other they can then be secured by solder
cement or the like.
In Figures 6 and 7 is shewn a further modification of the present invention.
In this form a number of groups of tongues h are stamped out of the sheet the
members of each group being in proximity to each other and in number according
to the length of note to be sounded the distance between the groups being
regulated according to the tune to be produced.
These tongues are raised up perpendicular to the sheet and the spaces between
the tongues of each group are filled with solder or other like material as shewn in
Figure 7 whereby strong and rigid projections of the required varying lengths are

page_text: formed. The number of single tongues in each group depends upon the length of
the projection of which they form part.
The smaller projections 1 and 2 are provided upon music sheets which are
suitable for musical boxes and the like while the longer projections 3 and 4 may
be used for the sheets or plates of such appliances as barrel organs which have to
produce notes sustained for some considerable time. For certain musical
instruments such for example as those in which a star wheel is employed for
actuating the sound producing devices projections of the particular form shewn
ati (Figure 8) forming teeth on the music sheets are provided for operating the
Baid wheel.
The said projections may be formed for instance in the manner shewn in
Figure 9 by means of the stamping tools kl and m. The two former tools are
firmly secured to the head of the stamping machine, so that when this is moved
down the tool / depresses out of the sheet N a tongue o, this tongue is rounded off
by being forced in contact with the counter stamp m and thereby caused to be
bent upwards.
Simultaneously with the movement of the head and immediately following the
last named operation the other tool k cuts out the smaller tongue p which is also
bent backwards against the tongue o by the counter tool m as shewn in Figure 8.
This small tongue p is for the purpose of firmly securing the larger tongue o in
position.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
1. A music sheet having projections formed by cutting the sheet and turning or
coiling over the cut portions as shewn for example in Figures 1 and 2 of the
accompanying drawings whether solder or like material be also applied thereto
or not.
2. A music sheet having projections formed by cutting and turning over pieces
of the sheet against or over one another substantially as hereinbefore described
with reference more particularly to Figures 4 and 5 of the accompanying
drawings.
3. A music sheet having projections formed by pieces stamped up in the form of
ears tongues or the like the spaces between being filled in with solder or other like
material so as to form the desired lengths of projections substantially as herein-
before described and illustrated by Figures 6 and of the accompanying drawings.
4. A music sheet having projections formed by cutting two tongues o p from the
sheet and turning them over one against the other substantially as herein before
described with reference more particularly to Figures 8 and 9 of the accompanying
drawings.
