IMPROVEMENTS IN ORGAN HARMONIUMS
Year: 1880

page_text: LETTERS PATENT to Peter Jensen, of 33, Chancery Lane, in the County of
Middlesex, for an Invention of "IMPROVEMENTS IN ORGAN HARMONIUMS."
A communication from abroad by Edmund Seches, of Paris, France.
PROVISIONAL SPECIFICATION left by the said Peter Jensen at the Office of
the Commissioners of Patents on the 19th August 1880.

MENTS IN ORGAN HARMONIUMS." A communication from abroad by Edmund
Seches, of Paris, France.
According to this Invention an instrument is constructed in which are combined
free reeds and organ pipes, all as hereinafter described. The free reeds are arranged
in connection with a sounding board with movable sonorous cases, such as described
in the Specification of the Patent, dated 18th August 1879, No. 3328. The bellows
are arranged so as to produce the wind by the same pedals, but differing according
to the pressure put on, the wind force being divided in two parts, one for the pipes
and the other, of half the strength, for the free reeds. The body of the instrument
consists of two parts, an upper and a lower part, which are detachable from each
other, for facilitating the transport and repair of the instrument and the tuning of
the pipes. The keyboard is arranged to draw out by means of slides on each side
of the instrument.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Peter Jensen in the Great Seal Patent Office on the 19th February

According to this Invention an instrument is constructed in which are combined

page_text: in connection with a sounding board with movable sonorous cases, such as described
in the Specification of the Patent, dated 18th August 1879, No. 3328. The bellows
are arranged so as to produce the wind by the same pedals, but differing according
to the pressure put on, the wind force being divided in two parts, one for the pipes
and the other, of half the strength, for the free reeds. The body of the instrument
consists of two parts, an upper and a lower part, which are detachable from each
other, for facilitating the transport and repair of the instrument and the tuning of
the pipes. The keyboard is arranged to draw out by means of slides on each side
of the instrument.
The accompanying Drawings illustrate the manner in which the Invention is
carried into effect. Figures 1 and 2 show the bellows, and Figures 3, 4, and 5 show
organ harmonium. In Figures 1 and 2, the pedals, which are operated in the
ordinary way, act on the bellows or feeders a, which have a capacity for air in
proportion to the size of the instrument; the air from the bellows issues into the
reservoir b, being that of the pipe organ; the reservoir c is that of the reed
harmonium, they are placed in communication by a throat d, which allows the
air in reservoir 6 to go into the reservoir c by means of a guide e fixed to the upper
part of the reservoir c.
The reservoir 6 carries a parallelogram and a rod connecting it to reservoir c
in such manner that as the reservoir b expands, the reservoir c receives a certain
quantity of air in proportion to the consumption; at the first stroke of the bellows
these reservoirs operate together owing to the parallelogram.

This harmonium with free reeds, the inventor proposes to place under a pipe
organ, and to use it as a simple harmonium by applying the aforesaid sonorous
cases to it, as well as the "coupler described in the Specification of the Patent,
No. 3328 (79), before referred to. At Figure 4 another combination on the
same principle is shown. At Figure 5 a complete organ is shown, where f is
the harmonium organ, and g the pipe organ; h, h, are the sonorous cases; the
air from the reservoir passes off by the passages j; the air from the reservoir c
passes off to the organ pipes by the passages k.
Having now described the nature of the said Invention, and in what manner
the same is to be performed, I declare that I claim as the Invention communicated
to me,-
First. The bellows arrangement, substantially as described and illustrated at
Figures 1 and 2 of the accompanying Drawings, which allows of the supply of air
to two independent instruments, one an organ with pipes, the other a harmonium
with free reeds.
Second. The arrangement before described and illustrated at Figures 3, 4, and 5
of an instrument which at will may be used as a harmonium with free reeds, or as
a pipe organ, or as a harmonium with free reeds and pipes.
In witness whereof; I, the said Peter Jensen, have hereunto set my hand
and seal, this Nineteenth day of February, in the year of our Lord One
thousand eight hundred and eighty one.
