19 Claims. (Cl. 84_177)
This invention relates to the top Wall of the for engaging the rear edge of the opening 2, to
casing of pianos.
limit the backward motion of the members 9,
Generally stated, the object of the invention is when the cover is closed. The shoulders II on
to provide a novel and improved construction the members 9 engage the inner side of the piano
whereby the top of the casing of a piano is pro
casing I 2 when the cover is pulled out and swung
vided with a sound outlet, and with a cover for into open position, as shown in Fig. 6 of the draw
said outlet, which can be closed when the piano ings. The under side of the cover, at its rear
is not in use.
Another object is to construct the said cover in
10 such form that, when opened, it may occupy an
inclined position above the keyboard, thereby to
serve also as a music-rack.
It is also an object to provide certain details
and features of constructon tending to increase
15 the general efliciency and desirability of a piano
casing top of this particular character.
To the foregoing and other useful ends, the
invention consists in matters hereinafter set forth
and claimed and shown in the accompanying
20 drawings, in Which
Fig. 1 is a perspective of a piano having a top
embodying the principles of the invention, with
the said cover in open position.
Fig. 2 is a similar view, with the lower portion
25 of the piano shown broken away for convenience
of illustration, and with the said cover in closed
position.

Fig. 3 is a horizontal section, on a smaller scale,
on line 3_3 in Fig. 5 of the drawings.
Fig. 4 is an enlarged vertical section on line
4_4 in Fig. 2 of the drawings.
Fig. 5 is an enlarged vertical section on line
5_5 in Fig. 3 of the drawings.
Fig. 6 is an enlarged vertical section on line
6_6 in Fig. 1 of the drawings.
Fig. 7 is a vertical section on line 'I_‘I inlFig.
5 oi the drawings.
Fig. 8 is a detail section on line 8_8 of Fig. 9,
showing a portion of the top construction.
Fig. 9 is a horizontal section on line 9_9 in
Fig. 8 of the drawings.
As thus illustrated, the invention comprises a
piano casing having a top wall I, formed with a
sound outlet opening 2 therein. Guide members
3 are suitably supported on the under side of the
top I, at the opposite ends of said opening 2, and
the inner guide members support the louvers 4
that extend lengthwise of said opening.
The cover 9 is shaped to iit said opening 2 and
50 is provided at its outer edge with a handle por
tion 6, as shown. This cover is hinged at 'I to
the under side of the outer ends 8 of the members
9 that are formed to slide in said guides, as shown
more clearly in Fig. 7 of the drawings. The
55 members 9 have shoulders I0 that serve as stops
edge, has a portion i3 that rests on the seat I4
when the cover is closed.
The top I, with its said cover 5, is in the form 10
of a removable unit which can be removably
fastened in any suitable manner upon the top of
the piano casing. For example, as shown in Figs.
8 and 9 of the drawings, the piano casing is pro
vided with sockets l5, having overlying metal 15
ì portions lâ, each provided with a hole I'I, having
a lateral slotl I8 at one side thereof. The under
side of the top I is provided with suitably formed
studs I9, adapted to pass through the holes Il of
the two metal devices I6, and adapted to then 20
enter the slots I3 of the two metal devices, there
by holding the top against displacement, except
that the top can thereafter be removed by sliding
it forward suñiciently to bring the heads of the
studs I9 into alignment with the holes I'I, so that 25
the top can then be lifted upward.
As thus constructed, the piano top has a cover
5 that can be opened and swung into the position
shown in Figs. 1 and 6 of the drawings, and in
such position it can be used as a music-rack, as 30
the handle 9 will support the music on the cover,
in convenient position above the keyboard of the
piano. When the cover is open, and the piano
is in use, the louvers 4 provide an outlet for the
sound waves. When the cover is closed, the top
surface of the piano is free from hinges or other
metal devices and presents an attractive appear
ance.
As shown in Fig. '7 of the drawings, the vertical
walls of the piano casing are provided with a
rubber gasket strip 29 for engaging the under
side of the top» I, when the latter is in place,
thereby in effect forming a practically dust-tight
top for the piano casing. It will be understood,
of course, that the said gasket can be made of
any suitable or desired material, anything that
is sufliciently soft or ñeXib‘le or resilient to serve
the purpose, and that the word “rubben” there
fore, is used in the generic sense as meaning a
gasket of any suitable material for this purpose, 50
not only to exclude dust, but also to prevent
vibration or rattling of the top.
While the invention is shown and described in
connection with an upright piano, a piano in
which the Sounding board is disposed vertically, 55
2,127,948
it will be understood that the invention can also
be used in connection with an ordinary grand
piano, or any piano in which the sounding board
is horizontal, and in which the casing has a
top wall of any suitable or desired character.
Thus, the cover 5 has three positions: a normal
or closed horizontal position, a forward hori
zontal position in the same plane, and an in
clined position when fully opened. In the first
10 and second positions, the top of the cover 5 is
flush with the upper surface of the top wall I of
the piano casing, and the said top wall and the
cover are removable intact as `a unit from the
top casing.
The opening of the sound opening
15 2 begins at the rear edge of the cover 5, and in
creases in extent as the cover is pulled forward,
and as the said opening 2 extends forward
through the front edge of the top wall I, be

the top wall, and a ledge for the front edge of
said cover, forming a handle by which to open
and close the cover.
6. A structure as specified in claim l, said
cover fitting said opening and being flush with
the top, and a ledge for the front edge of said
cover, forming a handle by which to open and
close the cover, having a hinge about which the
cover in its extreme forward position is movable
upwardly at its rear edge, which is the rear edge
of the cover, to form an inclined music rack,
with said handle forming a support for the lower
edge of the music.

position, and also a horizontal forward position,
Therefore, it is important to observe that in
in which latter the rear edge of the cover is
spaced a distance from the rear edge of said
accordance with the invention the rear edge of
the cover 5 is raised a distance above the hori
IO CR zontal plane of the top I, so that the front edge
of the cover is then below said plane, when the
cover is in position to form a music rack. The
slides 9 have top portions, as shown in Figs. 5
and 6, that extend above the guides 3 to sup~
30 port the cover in closed position.
