SECTION I - CLASS DEFINITION
This class includes the instruments used in producing music
and includes (1) electrical music instruments, (2) automatic instruments,
and (3) those hand played. The automatic instruments and the hand
played instruments have a parallel classification so far as seems
practical, and in both the patents are divided in the usual way
into four groups, stringed, wind, rigid vibrators, and membranes.
Then follow details or features common to groups (1), (2), and (3).
This class also includes some accessory devices generally recognized
as belonging to the art or industry.
SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
Instruments furnishing a sound of only one pitch, even if it
might be used for musical purposes, are generally to be found in
Class 116, Signals and Indicators; Class 446, Amusement Devices:
Toys, subclasses 207-209 and 397-422; Class 472, Amusement Devices,
subclass 64; or Class 623, Prosthesis (i.e., Artificial Body Members),
Parts Thereof or Aids and Accessories Therefor, subclass 9 for larynxes.
Phonographs, unless in combination with a recognized musical
instrument, are to be searched for in Class 369, Dynamic Information
Storage or Retrieval.
Printed music and systems of notation are to be found in Class
84 (this class), Music, subclass 483.2.
Bellows and wind flow regulators, unless specifically adapted
to musical instruments are to be found in Class 60, Power Plants;
subclasses 407-412; Class 91, Motors: Expansible Chamber Type; Class
92, Expansible Chamber Devices; and Class 417, Pumps.
Many features of construction or manufacture should be sought
for in woodworking or metal-working and many details not limited
to this art in appropriate classes, such as pedals, supports, clamps,
cases, springs, etc.
For instrument supports of general application not claimed
in combination with musical instruments or structurally limited
to use with specific musical instruments, see Class 248, Supports,
appropriate subclasses.

Note. The vibrating length of the string is determined by
its bearing on the two bridges, one on the sounding-board and the
other usually on the wrest-plank or on the string-plate. If on the
plate, it is sometimes distinguished as the "scale rib".
If the two bridges are not on the same side of the string, the one
near the hammer-line may be called "inverted". Often
the hammer-stroke tends to lift the string from the bridge on the
plank, so in some early pianos a sort of screw-eye called an "a
gaffe" was used, while in later times many sorts of clamps
or holders have been devised to hold the strings on their bridges,
and confusing names have been given them. | |

classifiable; also combinations of pipes and reeds.
| (1)
Note. The patents of this group may be classed as pipe organs,
reed organs, minor reed instruments, orchestral wood winds, and
brasses. The first two have many features in common; but they differ
so much in size and consequently in details that a parallel classification
has been made. Search should ordinarily be made in the proper subclasses
of both types and sometimes in "Automatics". Wind-supply
devices and pressure-regulators are mostly classed in Class 60, Power
Plants, and Class 417, Pumps. | |

or features not elsewhere classifiable. |
| |
332 | Actions: |
| This subclass is indented under subclass 331. Pipe-organ actions not belonging to a specific subclass.
| (1)
Note. The speaking of an organ-pipe is usually controlled
by the joint operation of devices actuated or controlled, respectively,
by a key and a stop. These devices (excluding the keys) are collectively known
as the "action". These actions and the corresponding
wind-chests are of three types: (1) the older, in which the top
of the wind-chest has as many grooves with pallets to control them
as there are keys and as many perforated slides crossing the grooves
as there are speaking-stops; (2) the type in which there are as
many stop-chambers as stops, each carrying a series or "register" of
pipes and each controlled by a valve or "ventil",
every pipe having its own valve controlled by a key, and (3) the type
in which all the pipes stand on a common or "universal" wind-chest
and each pipe has its own valve, which is jointly controlled by
a key and a draw-stop. In all three types the controlling means
may be mechanical, electrical, pneumatic, or electropneumatic. For details
of such means see this class, subclass 335, and following subclasses.
Patents for combinations of the first type are in this subclass. | |

switches in the circuits of electromagnets. |

341 | Electric: |

Note. In pneumatic and electric organ-actions, there is no

486 | Leaf turners: |
| This subclass is indented under subclass 453. Patents showing constructions not clearly belonging in one

types of leaf-turners.
| (1)
Note. Leaf-turners are devices to be attached to a music-stand
or to the music-desk of a piano to enable a player to turn one or
more leaves of music from right to left. In some cases the player releases
a source of power, in others he furnishes the power. In either case
he may use his hand, knee, or foot, and the terms "releaser" and "finger-piece" are used
generically herein to include also knee-levers and foot-levers.
Often a pedal is connected to operate a finger-key. Usually each
leaf is attached by clips to one or two arms extending from a solid
or tubular shaft pivoted near the line of fold of the music-sheets
or the line of the back of a bound book, said arms extending along
the top or bottom edge of the leaf or along both. This classification
is based, first, on the immediate source of the power that turns
the leaf-motor, gravity, spring, or hand--and, second, on whether
there is a plurality of parts or a single one of each kind. The parts
considered are only those of turning a leaf from right to left.
In many instances there are keys or pedals to return the leaves
from left to right. These are disregarded in the classification. |

be liberated by a releaser, trigger, key, or finger-piece. | |
