PROVISIONAL SPECIFICATION.
Improvements relating to American Organs, Harmoniums, and
the like.
I GEORGE EADON 34 Gorse Lane Swansea, Pianoforte Tuner and Repairer do
hereby declare the nature of this invention to be as follows:-
The object of my invention is to enable the pedals attached to American organs
and harmoniums to be used as an auxiliary to the foot boards for supplying wind to
or producing the necessary suction for enabling the reeds to speak. I accomplish
this as follows:-
The inner end of each pedal rests upon a hinged roller, beneath which is a
pivoted lever connected to the webbing actuating the bellows or exhauster. Upon
depressing any one of the pedals with the foot in the ordinary way a puff of wind
or sufficient suction is produced to cause the note to speak.
By this means the performer is enabled to remove both feet from the foot boards
for a short time when required for pedalling without interrupting the sound.
Improvements relating to American Organs, Harmoniums, and

I GEORGE EADON 34, Gorse Lane Swansea Pianoforte Tuner and Repairer
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 object of my invention is to enable the pedals attached to American organs,
and harmoniums, to be used as an auxiliary to the foot boards for supplying wind
to or producing the necessary suction for enabling the reeds to speak.
I accomplish this as follows :-
The inner end of each pedal rests upon a hinged roller beneath which is a
pivoted lever connected to the foot boards actuating the bellows or exhauster.
Upon depressing any one of the pedals with the foot in the ordinary way a puff
of wind or sufficient suction is produced to cause the note to speak.
By this means the performer is enabled to remove both feet from the foot
boards for any length of time when required for pedalling without interrupting the
sound.
The construction and operation of my invention will be readily understood by
reference to the drawing in which :-
Fig. 1, is a side view, the end cover of case being removed.
isa nlan of the mechanism beneath the pedals.

page_text: In the drawings 1, is the pedal lever pivoted at 2, in the usual manner and fitted
at its inner end with a shoe 3, adjustable by means of screws 4. Similar shoes are
adjustably fitted in the manner shewn to the inner end of each of the sharp or
natural pedals respectively. The shoes rest lightly upon wood rollers 5, which are
pivoted or otherwise mounted so as to turn freely in the holes formed in the sides 6,
of the iron lever frame 6. Each frame is hinged so as to move freely up and
down, by means of pins 7, passing through the blocks 8, secured to the base 9, of
the instrument. A spur 10, is riveted to or formed upon and preferably within the
sides 6 of the frames 6' against which presses the spring 11, fastened to or resting
upon the base 9. At any convenient point upon the back of each hinged frame 6' is
riveted or otherwise mounted a bent lever 12, the front end of which presses upon
a brass pad 13, screwed to the wooden lever 14, pivoted to the brackets 15, secured
to the base 9. Near the inner end of this lever a hole is formed through which
passes a metal piu and buckle 14¹ to which a leather strap 16, is secured, the
opposite end of the strap 16, is secured by buttoning or otherwise to the bellows
foot board 17, which is pressed upon by the feet of the performer in the manner
well understood, a piece of lead 18, is preferably secured as shewn to lever 14, to
assist the exhauster spring 19. These foot boards are also connected with the
exhauster 19, by webbing 20, passing over a friction roller or rollers 21, mounted
upon a pin 22, driven into a block 23, secured to any convenient part of the
instrument case.
The operation of my invention is as follows :-
The performer presses alternately upon the two foot boards 17, and thereby
operates by means of the webbing 20, secured thereto the exhauster 19, which
produces the suction necessary to operate the reeds mounted in the tube board 21,
beneath the pedals, and those controlled by the upper manual keys 25. As the
pedals are pressed down the adjustable shoe 3, mounted thereon presses upon
roller 5, and thereby forces down the frame 6' which in turn depresses by means of
the bent lever 12, the wooden lever 14, connected by the strap 16, with the foot
board 17, and webbing 20, secured to the exhauster, the effect of this being to
maintain the suction notwithstanding the fact that both feet have been removed
from the foot boards 17, for pedalling.
The drawing in Fig. 1, shews the general arrangement of exhauster and
reservoir employed in American organs.
In the case of an harmonium or equivalent instrument operating by wind pressure
forced direct from the wind chest through the reeds producing the sound; it is
sufficient to attach the strap 16, in each case to the foot board 17, which is
generally connected by a lever or equivalent means direct to the feeders or
bellows.
It will be seen that by means of my invention the performer is enabled to remove
one or both feet from the foot boards when required for pedalling, without
interrupting the sound; the suction or air pressure necessary for its production
being supplied by the action of the pedals.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination and use in or with American organs harmoniums and like
musical instruments of similar construction of the pedals as an auxiliary to the
foot boards, for supplying wind to or producing the necessary suction for enabling
the reeds to speak by the means, and in the way and manner, herein described.
2. In American organs, harmoniums and like musical instruments having pedals
the combination therewith of the shoes 3, having adjusting screws 4, which shoes
engage with the roller 5, carried by one or the other hinged frame 6'. The bent
lever 12, which when depressed operates lever 14, connected by strap 16, to the
foot board 17, for the purpose of producing suction or supplying wind to the reeds,

of pedalling substantially as herein described.
