I LORENTZ ALBERT GROTH K.G.V, Civil Engineer and Proprietor of the Patent
Industrial and Financial Agency, 30 Finsbury Pavement London E.C. do hereby
declare the nature of said invention for "AN IMPROVED METHOD OF MOVING THE
BELLOWS OF ORGANS, OR OTHER WIND INSTRUMENTS, BY MEANS OF A SPRING MOTOR
CONTROLLED BY PEDALS a communication to me from abroad by Professor Alois
Allmuth, of Stuttgart in the Kingdom of Wurtemburg, German Empire, to be as
follows:-
"
This apparatus is not a string arrangement or one necessitating the employment
of a second person nor is it one by which only a single stroke of the bellows
produces a short sound which must be repeated (by the foot) to prolong the sound
to the length required in organ music.
.
It consists of a spring motor in connection with the bellows and pedals of the
instrument which furnishes all the wind required and by means of which the
sound can be prolonged as long as the pedals are held down.
The spring motor consists of a spring box connected with a ratchet wheel and
cog wheel. The winding up of the spiral spring in the spring in the spring box is
effected by turning a shaft on the end of which is fixed a winch handle, which
directly moves conical wheels which set the cog wheel in motion the movements of
which are successively communicated to the fusee and axle-tree by a train of wheels
which finally also move the wings of a fly serving to regulate the entire movement.
Outside the axle of one of the wheels is a winch which is connected to two levers
by which the two bellows are alternately moved. A pedal starts or stops the
spring motor when required.

I LORENTZ ALBERT GROTH K.G.V. Civil Engineer and Proprietor of the Patent
. Industrial and Financial Agency 30 Finsbury Pavement London E.C. do hereby
declare the nature of said invention for "AN IMPROVED METHOD OF MOVING THE
BELLOWS OF ORGANS OR OTHER WIND INSTRUMENTS BY MEANS OF A SPRING MOTOR
t
CONTROLLED BY PEDALS " a communication to me from abroad by Professor Alois
Allmuth of Stuttgart in the Kingdom of Wurtemburg in the German Empire, and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
This apparatus is not a string arrangement, or one necessitating the employment
of a second person nor is it one by which each stroke of the bellows produces only 1
a short sound which must be repeated (by the foot) to prolong the sound to the
length required in organ music.
Fig. I shows the front of a reed instrument Z with spring motor A.
Fig. 2, a plan of same.
The spring motor A connected to the bellows B. by levers E, and to the pedals P. 1
furnishes all the wind required by means of which the sound can be prolonged as
long as the pedals are held down.
The spring motor consists of a spring box a Fig. 2 connected with a ratchet
wheel b and cog wheel d. The winding up of the spring is effected by turning a
shaft h on the end of which is a winch handle, which directly moves bevel wheels e. f.
which set the cog wheel d in motion the movements of which are communicated by
means of a train of wheels i. k. l. m. to the fusee and axle tree'n and tiually to the
wings of a fly o which regulates the entire movement.
Outside the axle b¹ is fixed a winch D to which are connected the lévérs E by
which the bellows are moved alternately.
There are two sets of reeds (an. 8 and 16 ft stop) the 8ft stop is operated by the
pedal key P¹ the 16 ft stop by the two pedal keys P2; while the pedal key P³ starts
or stops the spring motor A. as required by means of any suitable and known
arrangement, for instance, a pin or ironbar is connected with the back part of the
pedal key P³ in such way that, when the pedal key P³ is pressed down, the pin or iron
bar catches the fly O thereby stopping the spring motor A; but as this, being a
well known arrangement, is not included in the object of this patent, it is not shown
on the drawings.

page_text: 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 apparatus for moving the bellows of wind instruments consisting of a spring
motor connected to the bellows, and controlled by pedals as hereinbefore described
and illustrated in the drawings.
