An Improved Frame for the Reeds of Harmoniums, Accordions,
Concertinas, and other Musical Instruments with Metal Reeds.
We HEINRICH WILHELM SCHLUNZIG Senior and GÜNTHER KORNER of
Gera in the Empire of Germany Metal Reed Manufacturers 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 this invention is to construct reed frames for harmoniums American
organs accordion organs concertinas and other musical instruments furnished with
metal reeds in such a manner that the said frames will not oxydise it having been
found that the metal frames hitherto employed are very liable to oxidation
especially when exported across the sea and on arrival at their destination the
instruments furnished with such frames have to be taken to pieces and the reeds
and frames thoroughly cleaned.
Now according to our invention we make the reed frames for instruments as
herein before described of porcelain earthenware or other vitrified substance or of
suitable inoxydizable material ebonite for example.
And in order that our invention may be fully understood we will proceed to
explain the same with reference to the accompanying sheets of drawings in which :-
Fig. 1 represents longitudinal section of a reed and frame constructed according
to this invention. Fig. 2 is plan of same.
Fig. 3 is plan of reed frame with reed removed.
Fig. 4 is plan of underside of frame with reed attached.
Fig. 5 is section of reed shewing method of securing same to reed frame.
Fig. 6 is side elevation of a reed frame secured to the sound-board by means of
springs. Fig. 7 is side elevation of same. Fig. 8 is plan of same.
The same letters denote the same parts in all the figs.
c is the reed frame formed of glass earthenware porcelain or other vitrified
substance or of a composition which is unaffected by damp or acids vulcanite or
ebonite for example. This frame is of the usual size and shape or it may be thick
enough to allow full play to the reed without the necessity of cutting away the
sound-board under the reed b. The reed bis made of metal in the usual way and
is thickened or has a piece of metal fastened to it at e for tuning purposes.
The reed is secured to the frame c by means of a screw a passing through
holes in the reed and frame and engaging with the nut d the frame c being recessed
as shewn at Figs. 1 and 3 to receive the nut d.
Reed-frames constructed as hereinbefore described may be secured to the sound-
board by screws springs cement or other suitable means.
If springs are used to retain the reed frames in position I prefer to use springs
of approximately Z shape made from flat metal as shewn at y Figs. 6 7 and 8
the said springs being secured to the sounding board by means of screws in such
a manner that the said springs may be turned on the said screws as an axis as
shewn by the dotted lines Fig. 8 when it is desired to remove the reeds from the
sound-board.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. Constructing frames for the reeds of harmoniums organ accordions concertinas

page_text: and similar musical instruments of porcelain earthenware glass or other inoxydisable
material substantially as herein before specified and for the purpose stated.
II. Securing the metal reeds of barmoniums organ accordions concertinas and
similar musical instruments to reed frames constructed of inoxydizable material by
means of a screw passing through the reed and frame and engaging with
a nut in a recess in the underside of the frame substantially as hereinbefore
described and shewn at Figs. 1 4 and 5 of the accompanying drawings.
III. Securing reed-frames as claimed in Claim I to the sound-boards of
harmoniums organ accordions concertinas and similar musical instruments by means
of springs substantially as herein before specified.
