Improvements in the Method of and in-Apparatus-for-Blowing Pedal.
Organs and Harmoniums.
I, ALOIS HUGO LHOTA, of Heradec, Králové, Bohemia, in the Empire of
Austria, Manufacturer, do hereby declare the nature of my said invention and in
what manner the same is to be performed, to be particularly described and ascer-..
tained in and by the following statement :-
The object of my invention is to obviate the necessity of employing the feet
exclusively in supplying wind to organs and harmoniums having pedal notes, by
utilising the motions of the levers, in ordinary pedalling, to work the bellows.
And in order that my said invention may be particularly described and ascer-
tained, reference is hereby made to the accompanying drawings, in which similar
letters of reference indicate corresponding parts.
Fig. 1 is a sectional elevation of so much of an instrument as is required to.
illustrate my invention, showing the pedal keys or levers in their normal position
by solid lines; the dotted lines showing the method of operating the bellows.
Fig. 2 is a similar sectional elevation, showing the method of operating by solid
lines.
M is the ordinary bellows. a a is a lever pivoted at Y. t is a link or connecting
rod, pivoted to the lever a at b, and to the bellows board at c. Two of the levers a a
are fitted, one at each end of the pedal keys, and connected together by a longi-.
tudinal bar d, running under the whole set of pedals. m n are two fixed longitudinal
bars. o is a pin driven into the bars m n and passing through a slotted hole in the
pedal p, to keep the latter in position. is the ordinary sticker which is raised
and lowered by the action of the pedal p. s is a lever, pivoted at X, for working
the bellows independently of the pedals p p, when required. r is one of the
springs which are fitted to the pedals to raise them to their normal position after
the removal of the foot.
If the performer presses a key p down to its lowest position, the end p' will be
lifted up, until it rests against the bar m, thereby lifting the sticker h and sounding.
the note, which continues to sound as long as his so raised, while supplied with
wind. Wind can, however, be supplied if the pedal is not allowed to rise to its
normal position, but is worked up and down, from half way up to its normal position
and down to its lowest position, using m as a fulcrum. The sticker his thus kept
in a raised position and the bellows may be worked without interrupting the note..
The sound can also be graduated by the performer's foot with greater ease than
with ordinary instruments.
When long notes are not required, the ordinary pedalling will work the bellows,.
by pressing down the rod d and allowing it to rise between the notes, or by a partial
rising of the pedal while sounding the note.
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. In the construction of pedal organs and harmoniums, the combination of a
bar d attached to levers a, linked to the bellows M; the said bar d being operated
by any one or more of the pedals p, and thereby actuating the bellows M, substan-
tially as herein before described and illustrated by the drawings.
2. The improvements in the method of and in apparatus for blowing pedalį
