PROVISIONAL SPECIFICATION.
Improvements in Combined Pianos and Harmoniums.
I, JOSEPH MANUEL ARENCIBIA, of 44 Rue Delaborde, Paris, in the Republic of
France, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to a combined piano and harmonium and comprises the
combination of a mechanism designed for preventing the movement of the hammers
and permitting the separate use of one or the other instrument or of both
instruments at the same time.
In order that my invention may be clearly understood I have represented in the
accompanying drawings by way of example a piano in combination with an
harmonium.
Figure 1 shows the action of a piano and of an harmonium, the latter being
represented in the position which it occupies when the piano is intended to be
played alone.
Figure 1 is a continuation of Figure 1.
Figure 2 represents the position which the harmonium occupies when it is
designed to be played alone.
Figure 3 is a front view of the harmonium showing the arrangement of the
bellows and air reservoir.
It will be observed that my system comprises the combination, with the action of
the piano, of a bar a supported at each extremity by connecting rods set in motion
by a bent lever c which is connected to a rod d provided with a knob e.
If the knob e of the rod d is pushed the latter acts upon the bent lever c which
in its movement carries away the bar a, causing the push to recede from the
hammers so as to prevent them being operated by the keys, (see Figure 2).
i
By pulling the knob g after the hammers have thus been neutralized the levers h
are operated, these levers supporting the bar in which the rods j, connected to the
counter key levers of the harmonium, are adapted to slide.
It will therefore be seen that by pulling the knob the rods will pass below the
keys of the piano so that when the keys are acted upon the harmonium will be played
(see Figure 2).
My harmonium comprises an air reservoir 1 connected with the bellows m by
conduits n; these bellows m are set in movement either together or alternately by
means of a pedal mechanism o.
The operation of my combined piano and harmonium is as follows:
By pushing the knob g and pulling the knob e the piano will be played alone,
(Figure 1).
If the knob e is pushed and the knob g pulled the harmonium will be played
alone, (Figure 2).
By then pulling the knob e the two instruments will be played at the
same time.
It is understood that I may vary the forms and dimensions of my combined piano
and harmonium, and also arrange the bellows so as to be set in motion either
together or alternately by means of one or more pedals or knee-pieces.
I may also modify the forms and dimensions of my device of preventing the
movement the hammers and for transmitting the movement by the keys of the piano
to the counter keys of the harmonium.

page_text: Moreover I may employ in the manufacture of my instrument any material
which will ensure the best result.

COMPLETE SPECIFICATION.
Improvements in Combined Pianos and Harmoniums.
J, JOSEPH MANUEL ARENCIBIA, of 44 Rue Delaborde, Paris, in the Republic
of France, Manufacturer, 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 :-
My invention relates to a combined piano and harmonium and comprises the
combination of a mechanism designed for preventing the movement of the hammers
and permitting the separate use of one or the other instrument or of both
instruments at the same time.
In order that my invention may be clearly understood I have represented the
same in the drawings left with my Provisional Specification which shows by way
of example, a piano in combination with an harmonium.
Figure 1 shows the action of a piano and of an harmonium, the latter being
represented in the position which it occupies when the piano is intended to be
played alone.
Figure 1 is a continuation of Figure 1.
Figure 2 represents the position which the harmonium occupies when it is designed
to be played alone and
Figure 3 is a front view of the harmonium showing the arrangement of the
bellows and air reservoir.
It will be observed that my system comprises the combination, with the action of
the piano, of a bar a supported at each extremity by connecting rods 6 set in
motion by a bent lever c which is connected to a rod d provided with a knob e.
If the knob e of the rod d is pushed the latter acts upon the bent lever c which
in its movement carries away the bar a, causing the push f to recede from the
hammers so as to prevent them being operated by the keys (see Figure 2).
By pulling the knob g after the hammers have thus been neutralized the levers h
are operated, these levers supporting the bar i in which the rods j, connected to the
counter key levers k of the harmonium, are adapted to slide.
It will therefore be seen that by pulling the knob g the rods ; will pass below
the keys of the piano so that when the keys are acted upon the harmonium will
be played (see Figure 2).
My harmonium comprises an air reservoir l connected with the bellows m by
conduits ; these bellows m are set in movement either together or alternately by
means of a pedal mechanism o.
The operation of my combined piano and harmonium is as follows:
By pushing the knob y and pulling the knob e the piano will be played alone
(Figure 1).
If the knob e is pushed and the knob g pulled the harmonium will be played
alone, (Figure 2).
By then pulling the knob e the two instruments will be played at the same time.
It is understood that I may vary the forms and dimensions of my combined
piano and harmonium, and also arrange the bellows so as to be set in motion either
together or alternately by means of one or more pedals or knee-pieces.
may also modify the forms and dimensions of my device for preventing the

page_text: movement of the hammers and for transmitting the movement by the keys of the
piano to the counter keys of the harmonium.
Moreover
may employ in the manufacture of my instrument any material which
will ensure the best result.
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 a combined piano and harmonium the combination of the two instruments
played together or separately by means of a device for neutralizing the operation
of the hammers, which consists of a bar a supported by rods set in movement by
a bell-crank lever c connected to a rod d provided with a knob e, as described and
shown in the drawing.
2. In a combined piano and harmonium the combination of the two instruments
played together by means of a device comprising a knob g operating the levers h,
bar i, rods and consequently the counter-key levers k of the harmonium, as
described and shown in the drawing.
