Improvements in the Construction of Accordions:
I, DEMID SIMANOK, of 1, Meschanskaja, Moscow, in the Empire of Russia,
Peasant, do hereby declare the nature of this invention to be as follows:-
The improvements in the construction of accordions are represented in the
annexed drawings, and relate to the construction of the bellows, the keys, and
the ends.
The bellows. In place of making the bellows as is usual by folding leather,
cloth, or even paper, in one and the other direction and sticking the ends, I make
it upon al skeleton of metal wire " wound in દ helix as in
Figure 1, or wound in a helix round a square core as in Figure 2.
This skeleton is placed inside a tube or leather pipe which tightly
surrounds it and thus forms the bellows. To produce greater regularity in the
folds I surround the wire of the skeleton, from the outside, with a strip of thin
metal of arch shape (Figure 3) which pinches the cloth c of the bellows against
the skeleton a in such a manner as to produce perfectly regular folds or more
properly speaking a continuous fold of helicoidal form.
heys. Figures 4 and 5 show in vertical and horizontal section the method of
carrying the keys. The keys are mounted as is usual in grooves in a wooden
cross bar or support d fixed to the end of the instrument. The keys are each
formed of a metal plate e provided at its top with a disc f, the key properly so
called, and at its base with a bent metal wire carrying the valve h which
covers the hole through which the air escapes. By the side of the key, and in
the same groove in the support d, I place a spring i which tends to maintain the
valve against the end of the instrument. All the keys are pivotted upon the
rod which traverses the wood of the support d.
The ends Figures 6 and 7 are of metal and are fixed to the wooden frames m
by means of nails or otherwise. The cloth of the bellows is secured between the
turned up edges of the ends and the frames m. The frames are provided with
grooves in which the ends of the skeleton a are located, which ends may be fixed
there by nails or otherwise.

invention.

page_text: same is to be performed to be particularly described and ascertained in and by
the following statement:-
The improvements in the construction of accordions are represented in the draw-
ings left with the Provisional Specification and relate to the construction of the
bellows, the keys, and the ends.
The bellows. In place of making the bellows as is usual by folding leather,
cloth or even paper, in one and the other direction and sticking the ends together,
I make it upon a skeleton of metal wire a wound in a helix as in
Figure 1, or wound in a helix round a square core as in Figure 2.
This skeleton is placed inside a tube or leather pipe which tightly
surrounds it and thus forms the bellows. To produce greater regularity in the
folds I surround the wire of the skeleton, from the outside, with a strip of thin
metal of arch shape (Figure 3) which pinches the cloth c of the bellows against
the skeleton a in such a manner as to produce perfectly regular folds or more
properly speaking a continuous fold of helicoidal form.
Keys. Figures 4 and 5 show in vertical and horizontal section the method of
carrying the keys. The keys are mounted as is usual in grooves in a wooden
cross bar or support d fixed to the end of the instrument. The keys are each
formed of a metal plate e provided at its top with a disc f, the key properly so
called, and at its base with a bent metal wire carrying the valve h which
covers the hole through which the air escapes. By the side of the key, and in
the same groove in the support d, I place a spring which tends to maintain the
valve against the end of the instrument and thus close the wind hole. All the
keys are pivotted upon the rod k which traverses the wood of the support d.
The ends Figures 6 and 7 are of metal and are fixed to the wooden frames m
by means of nails or otherwise. The cloth of the bellows is secured between the
turned up edges of the ends and the frames m. The frames are provided with
grooves in which the ends of the skeleton a are located, which ends may be fixed.
there by nails or otherwise.
Figure 8 shews in elevation an accordion constructed in accordance with this
invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is-
1. Constructing the bellows of a skeleton of wire wound in a helix and sur-
rounded with fabric or other suitable material the same being secured upon the
wire by a strip of thin metal of arch section.
2. Constructing the metal keys cach of a metal plate provided at the top with
a disc and at the base with a wire carrying the valve.
3. Constructing the ends in metal the curved edges of each end pinching the
fabric of the bellows.
