Improvements in Organs.
EDWIN SMITH, Organ Builder & Piano Dealer, Mount Strect Organ Works,
Blackburn, Lancashire, do hereby declare the nature of this invention to be as
follows:
An entirely new and improved form of atmospheric pneumatic pallet, or, electro-
atmospheric pallet, whereby, in the former case tubular pneumatic wind is used,
and in the latter, pneumatic wind supply from keyboard to soundboard, may be
wholly dispensed with.
In the application of this system a new form of soundboard is used, which may
be a slider, or sliderless, muted, or ventil soundboard, on the exterior top of
which is placed small chambers one for each note-in which are fixed expanding
& contracting motor pallets, which closes or opens the windway from soundboard
to pipes, which pipes stand on the top side of the chambers refered to; The top
side of the motor pallet is perforated as a means of admitting or expelling
atmosphere to or from the enterior of said motor pallet, which motor pallet is
fixed to the interior of the small chambers referred to, in any suitable position
but preferably to the top; the whole on the outside of the sound board but may
be inside, inverted, separated--motor from pallet-and otherwise varied.
A connection (by wire or trace of any kind) is made from the pallet motor, to
a small internal motor fixed permanently to the bottom of soundboard, which
internal motor is also perforated and open to the atmosphere, either directly, or,
by means of pneumatic tubing of any diameter, but preferably from 1/16" to "-
and any reasonable length, and can be operated by admitting wind from a supply
chest of any description to the interior of last named motor, when the pipe, or
pipes speak, and vice versa are silent on cutting off wind supply, a perfect and most
sensitive repetition being obtained; it is also operated by closing the opening or
orifice in the internal motor communicating with the atmosphere, by means of a
small armature worked from a small electro magnet current being obtained from
a suitable battery, and contacts-make & break-being made by the key, or by
any other suitable means.
This atmospheric pneumatic pallet is also used for facilitating coupling, group-
ing, combining &c. the various stops or sets of pipes, either pneumatically, or
electrically by closing the orifice leading to the internal motor thus cutting off
atmospheric communication.
Drawstops, and other like movements may similarly be worked, either pneu-
matically, or electrically-by cutting off atmospheric connection with the interior
motor.
I claim an entirely new form of pneumatic pallet,
The peculiar position of the twin motors, in conjunction with the wind pressure
inside the soundboard (or windchest) and the lighter atmospheric pressure without,
produces in operation the desired speech or silence of any or all the pipes when
sliders, mutes or ventils, are drawn by the stops for playing upon; together with

page_text: the novel form or construction of soundboards, windchests, coupling chambers &c.
suitable for the same.
EDWIN SMITH, Mount Street Organ Works, Blackburn, Organ Builder, 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:
The improvement consists of a soundboard divided into any number of stops,
ventils, or wind chests, fitted with a novel valve or pallet, formed by a combination
of two small bellows or motors, attached together in such a manner that the same
wind closes or opens the pallet as desired.
The motors are so arranged as regards size & position so that the power motor (A)
which is always superior in size & area to the pallet motor (B) is closed by
the wind in the wind chest (FF) the pallet motor (B) being attached by means
of a wire (C) or any kind of a trace-to the power motor, is also closed.
On the admission of wind from the power motor feed chest (D) through the
channel (E) to the interior of the power motor (A) the wind in the wind chest (FF)
blows open through the passage (G) the motor pallet, (B) admitting wind into the
cavity (H) and to the pipe or pipes (I) standing over the same. The interior of
the motor pallet is open to the atmosphere.
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:
The novel form of pallet, and the means of operating the same.
The novelty consists of the pallet being opened by the wind, and closed by
the same wind, no springs being used-the same wind also giving speech to the
pipes; also, in being placed outside the windchest (FF) in the cavity; (H) the
simplicity of construction, and the perfect manner in which pipes can be made
to speak or repeat,-even at great distance, also, in its particular adaptability
to electric actions, detached consoles, and divided organs.
