Improvements in Portable Harmoniums
We, JOSEIH WALLIS & SON, LIMITED, of 133 and 135, Euston Road, in the
County of London, Manufacturers, do hereby declare the nature of this invention
(a communication to us by Maurice Kastel f92, Rue d Augoulème, Paris, in the
Republic of France, Musical Instrument Manut icture) and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement
This invention relates to improvements in portable harmonium whereby we are
cnabled to dispense with the use of the stand which now usually forms part of the
stiument as the improved construction of the intrument illows of it being placed
on a table on the like
For this purpose, instead of placing the bellow
The
in the bottom or underside of
the insti ument as hitherto, we place the bellows on the top of the instrument in
such a manner that the same can be operated either by hand or by foot
suction valves are placed at the back of the instrument and open into
which communicates directly with the air chamber of icservoir bellow.

To enable the invention to be fully unaci stood we will describe the sune by
reference to the accompanying diawings, in which

our invention

page_text: Figure is a side view of a pedal adapted to operate the bellows of the
harmonium
Figure 5 is a plan of the pedal when shut
a is the feed bellows placed on top of the harmonium instead of on the bottom
or underside of the same as hitherto, the top of the said bellows being hing dat one
end and kept normally open under the action of a spiral spring a¹ is the passage
formed inside the harmonium at the back of the same, the said passage communi-
cating with the bellows a and with the exterior oy means of holes c, c provided on
the inside with strips of leather forming suction valves The air passage b is bent
at its lower end at right angles and is provided with a valve d opening outwards
into a chamber which communicates with the reservoir bellows e through the
hole or passage f
It will be obvious that when the feed-bellows is operated the air will pass through
the holes c, c into the passage b and thence through the valve d into the reservoir
bellows e from which it escapes in the usual manner
The feed-bellows can be actuated either by hand or by foot in the latter case
we preferably employ the pedal represented in Figures 4 and 5 and which is
formed of two flat plates 9 and 1 hinged togethui at one end The two plates g
and are kept normally apart by the sping and the plate his connected to the
bellows a of the harmonium by means of a strap, passing over a hook k on the top
of the latter The plate g is preferably provided with spikes so as to ob ain a hold
on the ground and the bellows a is operated by depressing the plate by the foot
in the usual manner
7 is a hook designed to hold the feed bellows closed by engaging with the
hook h
Having now particularly described and ascertained the nature or the said
invention and in what manner the same is to be performed, we declare that what
we claim is
1 A portable harmonium having the feed-bellows airanged on the top and a
passage putting the said bellows in communication with the reservoir bellows of the
harmonium, substantially as de cuibed
2 The manufacture and use of the improved portable harmonium hereinbefore
described and illustrated in the accompanying drawings
