Improvement in Mouth Organs.
I, EMILE RINDSKOPF, of 24 Milton Street in the City of London, Merchant's
Manager, do hereby declare the nature of the said invention and in what manner
the same is to be performed to be particularly described and ascertained in and by
the following statement, that is to say :-
This invention relates to an improvement in mouth organs whereby the tone
thereof can be increased or strengthened at pleasure and consists in the employment,
in connection with the two reed plates usually employed, of a third or supplementary
reed plate and a cover or key whereby the reeds of the said supplementary reed
plate can be caused to sound or not as may be desired. And in order that the said
invention may be fully understood I will now proceed to describe the same with the
aid of the accompanying sheet of drawings in which
Figure 1 is a view as seen from above of a mouth organ with the said improvement
applied thereto..
Figure 2 is a section taken at line X X of Figures 1. 3 and 4 the shields DD'
shown in the latter figures being supposed to be removed in Figure 2.
Figure 3 is a section taken on line Y Y of Figure 2 showing the aforesaid cover
or key closed,
Figure 4 is a similar section but showing the aforesaid cover or key opeu and
Figure is a plan partly in section of the body of the instrument showing the
position and arrangement of the air channels.
A is the body of the instrument made of wood or other suitable material in the
usual way. BB' are the air channels leading to and from the reeds of the two
ordinary reed plates C C respectively. DD' are the usual shields secured over
the reed plates CC. These shields are closed at the front where the mouth is
applied but are open at the back for the admission of air to, or its escape from, the
reed plates C C according as the air is drawn through the reeds into the mouth or
blown thereby through the reeds. E are special air channels or cavities which are
connected by small passages F with certain of the ordinary air channels B. Gis
the supplementary reed plate above mentioned, the reeds of which stand over the
special air channels E. H is a cover or key faced with leather H' and hinged at I
to a small carriage J fixed to the body A of the instrument. H2 is a finger piece
forming part of the cover or key H and by which the latter can be raised or opened
into the position shown in full lines in Figure 2. K is a spring which presses the
cover or key H down on to the reed plate G into the position shown in dotted lines
in Figure 2 when the finger is removed from the finger piece H.
It will now be understood that so long as the cover or key H remains closed
against the reed plate G only the reeds of the reed plates CC can be sounded
because no air can pass through the reed plate G; but when the cover or key H is
opened air passes through the reed plate G and the reeds thereof sound in unison
with those of the reed plates C C'. That is to say, when the cover or key H is
open and air is drawn into the mouth through any of the channels B that are in
communication with the channels E, air enters through one set of the reeds in the
reed plate G into the channels E, then passes through the passages F into the air
channels B and so to the mouth. Similarly when air is blown from the mouth into
any of the channels B that are in communication with the channels E part of it
passes through the passages F and the channels E, and thence through the other

page_text: set of reeds of the reed plate G; in either case causing the said reeds to sound and
to swell or strengthen the tone as above explained.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is :-
The improvement in mouth organs which consists in the employment, in addition
to the usual reed plates CC, of a supplementary reed plate G fixed over air
channels E which are in communication with air channels B belonging to the other
reed plates, the said supplementary reed plate G having a cover or key H whereby
air can be admitted to or shut off from such reed-plate according as the notes for
swelling or strengthening the tone are to be sounded or not, substantially as herein-
before described and illustrated in the drawings.
Dated this 26th day of April 1893.
