www Turn Down Kunning w SORANAM DAY A "
PROVISIONAL SPECIFICATION left by the said Jacques Verreyt at the
Office of the Commissioners of Patents, with his Petition, on the 4th
July 1867.
I, JACQUES VERREYT, of Ixelles, near Brussels; in the Kingdom of Belgium,
do hereby, declare the nature of the said Invention for "IMPROVEMENTS IN
ORGANS WITH: Two,, THREE; OR FOUR KEYBOARDS AND' SEPARATE PEDAL ACTION;" to
be as follows:-
The object of my Invention is to obtain all the resources and combinations?
of effect with one keyboard of an organ having two keyboards that up to the
present. time have only been obtained with two keyboards in connection with
separate pedals and pipes, sound boards, and special mechanism.
My improved system of manufacturing organs allows the organist to
transpose altogether, or in part. the action on the rows of pipes of which the
organ is composed from the first keyboard to the second, and vice versa; as
well as to the pedals. The: flute 8 ft. pipe and the bourdon 16 ft. pipe, for
example, can be played by the pedals with the aid of special stops instead of

page_text: causing them to be sounded by the keys on the keyboard, and each row of
pipes can be divided into several distinct rows and distributed among the
different keys. In causing the pedals to communicate with the flute 8 ft.
pipe and the sub-bass 16 ft. pipe, the first keyboard with the bourdon 8 ft. pipe
and the open diapason 8 ft. pipe, and the second keyboard with the flute
harmonic 8 ft. pipe greater variations will be produced than would be possible
with an organ with a single keyboard of however many pipes it was composed.
Such varied combinations of effect cannot be obtained with the ordinary con-
struction of organs unless there are two complete keyboards, each having 56
keys in connection with separate pedals, and distinct and special pipes com-
municating with each keyboard.
In order that this Invention may be well understood I annex the accom-
panying 2 Sheets of Drawings representing an organ having eight rows of
pipes and 17 stops placed upon one sound board and communicating with
two keyboards, and also one set of separate pedals, but the number of pipes
and stops can be diminished or increased at pleasure.
Fig. A, Sheet 1, of the accompanying Drawings is a front view of the
general arrangement of the organ. Fig. B is a side view of the same, and
Fig. C is a horizontal section through the organ taken at a line above the
sound board. Although the keyboards h are placed upon the left side of the
organ in the Drawing they may be situated on either side or in the middle of
the organ, or isolated from it and placed upon a small separate case.
Fig. D, Sheet 2, is an arrangement of the wind bars and spaces of the
sound board, which board i is divided into 112 spaces J, each alternate one
corresponding to the 56 keys of each keyboard. Of the 56 spaces. which
communicate with the swell 27 are divided into two compartments. The
27 smallest are in communication with the 27 pedals, and the others cor-
respond to the notes of the swell.
With this arrangement of the wind bars 9
and of the spaces I can with the aid of ordinary slides which intercept or
give access to the air make a single pipe sound separately or simultaneously
with others.
Fig. E is Fig. D shut, but leaving free the reserved places p for the
application of the valves l. These valves are for admitting the compressed
air contained in the said air chambers into the spaces, and they themselves
are supplied by the bellows.

division of the pipes n, and the distribution of the escape valves o.. The lines
drawn in red and black shew the division of the slides, the action of the slides
regulating at pleasure, whether the pipes separately or simultaneously shall

page_text: be acted on by the keyboard of the great organ, or that of the swell or the
pedals.
I apply similar improvements to organs with three or four keyboards, but
in this case the number of the principal parts which constitute the instrument
must be increased. Thus the number of pipes being increased it would be
necessary to have a more powerful bellows, and instead of one sound board to
contain all the pipes' it would require two, and the compound pedals and
mechanism in general would have to be increased in proportion.
SPECIFICATION. in pursuance of the conditions of the Letters Patent, filed
by the said Jacques Verreyt in the Great Seal Patent Office on the
3rd January. 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JACQUES
VERREYT, of Ixelles, near Brussels, in the Kingdom of Belgium, 'send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of July, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirty-first year of Her:
reign, did, for Herself, Her heirs and successors, give and grant unto me,'
the said Jacques Verreyt, Her special licence that I, the said Jacques
Verreyt, my executors, administrators, and assigns, or such others as I,
the said Jacques Verreyt, my executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at all timės
thereafter during the term therein expressed; should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for "IM-
PROVEMENTS IN ORGANS WITH Two, THREE, OR FOUR KEYBOARDS AND SEPARATE
PEDAL ACTION," upon the condition (amongst others) that I, the said Jacques
Verreyt, my executors or administrators, by an instrument in writing under
my, or their, or one of 'their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same
was to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said Jacques Verreyt, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following

page_text: statement thereof, reference being had to the accompanying two Sheets of
Drawings (that is to say) :-
The object of my Invention is to obtain with one keyboard of an organ
having two keyboards all the resources and combinations of effect that up to
the present time have only been obtained with two keyboards in connection
with separate pedals and pipes, sound boards, and special mechanism.
My improved system of manufacturing organs allows the organist to
transpose altogether or in part the action on the rows of pipes of which the
organ is composed from the first keyboard- to the second, and vice versa, as
well as to the pedals. The flute 8 ft. pipe and the bourdon 16 ft. pipe, for
example, can be played by the pedals with the aid of special stops, instead of
causing them to be sounded by the keys on the keyboard, and each row of
pipes can be divided into several distinct rows and distributed among the
different keys. In causing the pedals to communicate with the flute 8 ft.
pipe and the sub-bass 16 ft. pipe, the first keyboard with the bourdon 8 ft.
pipe and the open diapason 8 ft. pipe, and the second keyboard with the flute-
harmonic 8 ft. pipe, greater variations will be produced than would be possible
with an organ with a single keyboard of however many pipes it was composed.
Such varied combinations of effect cannot be obtained with the ordinary con-
struction of organs unless there are two complete keyboards, each having 56
keys in connection with separate pedals, and distinct and special pipes.com-
municating, with each keyboard.
In order that this Invention may be well understood I annex the accom-
panying two Sheets of Drawings representing an organ having eight rows of
pipes and 17 stops placed upon one sound board and communicating with two
keyboards, and also one set of separate pedals, but the number of pipes and
stops can be diminished or increased at pleasure.
Fig. A, Sheet 1, of the accompanying Drawings is a front view of the
general arrangement of the organ. Fig. B. is a side view of the same, and
Fig. C is a horizontal section through the organ taken at a line above the
sound board. Although the keyboards h are placed upon the left side of the
organ in the Drawing, they may be situated on either side or in the middle of
the organ, or isolated. from it and placed upon a small separate case.
Eig. D, Sheet 2, is. an arrangement of the wind bars and spaces of the
sound board, which board: i is divided into 112 spaces J, each alternate one
corresponding to the 56 keys of each keyboard. Of the 56 spaces which
communicate, with the swell 27 are divied into two compartments. The 27
smallest k are in communication with the 27 pedals, and the others correspond
to the notes of the swell. With this arrangement of the wind. bars 9 and of

page_text: the spaces I can, with the aid of ordinary slides which intercept or give
access to the air, make a single pipe sound separately or simultaneously with
others.
Fig. E is Fig. D shut, but leaving free the reserved places p for the
application of the valves 1. These valves are for admitting the compressed air
contained in the said air chamber into the spaces, and they themselves are
supplied by the bellows.
Fig. F represents a plan and Fig. G a front view of the sound board, the
division of the pipes n and the distribution of the escape valves o. The lines
drawn in red and black shew the division of the slides, the action of the slides
regulating at pleasure whether the pipes separately or simultaneously shall
be acted on by the keyboard of the great organ, that of the swell, or the
pedals.
I apply similar improvements to organs with three or four keyboards, but
in this case the number of the principal parts which constitute the instrument
must be increased. Thus the number of pipes being increased it would be
necessary to have a more powerful bellows, and instead of one sound board
to contain all the pipes it would require two, and the compound pedals and
mechanism in general would have to be increased in proportion.
In witness whereof, I, the said Jacques Verreyt, have hereunto set my
hand and seal, this Twenty-sixth day of December, in the year of our
Lord 1867.
