More particularly ‘referring now to the draw 10
ings, the music desk of a grand piano usually
comprises a member I pivoted at 2 so that it is
adapted to assume the position shown in Figure 2
when erected. When not in use the music rest I
is adapted to be pivoted around the hinge 2 so
that the upper end will move to the left as
viewed in Figure 2, that is toward the front of the
piano. The supporting member 3 is then adapted
to slide backwardly to closed position. There is 20
also provided a stringer 4 against which the lower
edge of the music rests. The music racks l on
various pianos are of different heights. The
height of the music rack above the keys on dif
ferent pianos is different and the support upon 25
which the music rack I is pivoted likewise is dif
ferently positioned and has different amplitudes
of motion. Furthermore, the angle which the
music rest I assumes when in erected position is
different on different pianos.
80
For grand pianos my music rack comprises a
board 5 to which is hingedly connected a member
6. Member 6 is provided with a groove 1 in which
the tongue 8 of clamp member 9 is adapted to
ride. An auxiliary clamping member l0 may be
provided. The pivotal connection between mem
bers 5 and 6 may be by means of ?exible mate
rial H glued or otherwise secured to both mem
bers 5 and 6. The back of members 5 and 6 may
be covered by felt l2 to prevent scratching the
music rest of the piano. In use the clamping
assembly is clamped over the top of the music rest
of the piano by means of a clamping bolt l3 with
the lower end of board 5 positioned against the
stringer 4 as can readily be seen by reference to 45
Figure 2. In this position the board 5 will act as
a brace preventing the music rest of the piano
from pivoting around its hinge 2. The board 5
also acts as a support upon which the auxiliary
music rack is adjustably mounted as will herein 50
after more fully be pointed out.
Referring now to Figure 6 there is shown a
bracket. One end M of the bracket I5 is adapt
ed to embrace the board 5 as can readily be seen
by reference to Figures 3 and 4. To the arms I6 55
2,133,368

of the bracket I secure the auxiliary music rest
proper IT, by means of a clamp bolt l8. clamped
between the arm I6 and the music rest II are
a pair of wedges l9 and 20 through which the
angle of clamping can be readily adjusted. It
will be observed that if both narrow portions of
the wedges are downwardly the angle between
the brackets l6 and the plane of the music rest
I? will be less than 90°, as shown in full lines in
10 Figure 2. By positioning one thin end upwardly
and one thin end downwardly the angle can be
made to be 90°, as shown in dotted lines in Fig
ure 2 and in full lines in Figure 7. By placing
both butt ends of the wedges together and posi
15 tioning them downwardly, the angle between the
bracket l6 and the plane of the music rest ll can
be made greater than 90°. It will be observed by
intermediate positioning of the wedges, any de
sired angle between the limits of the wedges can
20 be achieved. Likewise, different angles can be
obtained by using only one of the two wedges
of a clamping bolt 3!. In this manner various
heights can be readily accommodated. The up
per end of the member 26 is clamped to the up
per end of the music rest 24 by means of the
clamp 28. The music rest is moved to open po
sition, as shown in Figure 10, and the lower end
of the board 30 is placed against the stringer 32
of the piano. The clamping bolt 3! is then
clamped to the music rack ll and its bracket
with embracing end I4 is positioned upon the 10
board 38 precisely in the same manner as upon
board 5; board 30 and board 5 being made of
the same weight and thickness.
It will be observed that I have“ accomplished
the objects of my invention. I have provided an 15
adjustable auxiliary music rack which may be
used upon all makes of grand and upright pianos.
The construction is such that it will not scratch
the piano, is light in weight, is easily adjusted
and will provide a music rack which will enable 20
children to have the music properly positioned,
or by using wedges having diiferent angles. In
thus avoiding nervous strain and fatigue occa
this manner a simple adjustment to obtain the
desired angle for the music rest H is achieved.
25 The bracket 55 is made of malleable metal and
the arm iii of the bracket is secured to the music
sub~combinations are of utility and may bev em
rest ll through slots 2 I.
‘
Referring now to Figure 3 it will be noted that
the distance between end M of the bracket and
the music rest I? is greater than this distance
in Figure 4, thus providing an adjustment of dis
tance of the music rest from the board 5 to en
able the music rest to be used on pianos having
sioned by improperly positioned music.
It will be understood that certain features and

ployed without reference to other features and
sub-combinations. This is contemplated by and
is within the scope of my claims. It is further
obvious that various changes may be made in de
tails within the scope of my claims without de 30
parting from the spirit of my invention. It is,
therefore, to be understood that my invention is
not to be limited to the speci?c details shown and
described.
Having thus described my invention, what I
‘claim is:

invention when used upon upright pianos. In
this type of piano the music rest usually com
prises a pivoted panel 24 which is always a greater
depth than the music rest I provided upon grand
165
pianos.
The same principles, however, are in
volved, namely, to prevent the music rest 24 from
pivoting around its axis 25 and to permit the
bracing means to act as a support for an auxil
iary music rest. The same auxiliary music rest
is used. The support comprises an elongated
member 28, carrying ‘a bracket 27 at its upper
end. The bracket is provided with an adjustable
clamp 28. The member 26 is provided With a
slot 2Q in which a board 30, similar to board 5,

member, an auxiliary music rest supported by
said bracket, and means for adjusting said aux
iliary music rest to positions whereby said aux
iliary music rest will occupy planes forming vari
ous angles with the plane of the music rack of
the piano.
4. An auxiliary music rest adapted to be used

bracket on said combined bracing and supporting
member, an auxiliary music rest supported by
said bracket, means for adjusting said auxiliary
music rest to positions whereby said auxiliary
music rest will occupy planes forming various
angles with the plane of the music rack of the
piano, and means for adjusting said auxiliary
music rack to planes lying at di?erent distances
from the plane of the music rack of the piano.
5. An auxiliary music rest as in claim 3, where
in said means for angularly adjusting said aux
iliary music rest comprises means for clamping
said music rest to said bracket and wedges adjust

in said means for positioning said music rest at
different distances from the music rack of the
piano comprises slots in said music rest whereby
said bracket may be bent to present various nor
mal distances between said music rest and music
rack.
7. A music rest as is claim 3, wherein said means
for clamping said bracing means is pivotally con
nected to said bracing means and said clamping
means is longitudinally adjustable to enable it 10
to be used on piano music racks of various heights.
8. A music rest as in claim 2, wherein said
means for adjustably positioning said bracket
upon said combined bracing and supporting
means comprises bracket portions at least par 15
tially surrounding said supporting means, with
su?icient clearance whereby said bracket is adapt
ed to rotate about a horizontal axis lying sub
stantially in the plane of said bracing member, to
frictionally clamp said supporting means between 20
front and rear portions of said bracing means.
