page_text: LETTERS PATENT to Alexander Horace Brandon, of 13, Rue Gaillon,
Paris, France, Civil Engineer, for the Invention of "AN IMPROVED
CONSTRUCTION AND ARRANGEMENT OF ORGAN PIPES AND THE VALVES AND AIR
PASSAGES THEREOF FOR PARLOR, REED, AND KEY-BOARD MUSICAL INSTRU-
MENTS." A communication from Carl Fogelberg, residing at Boston,
Massachusetts, United States of America.
Sealed the 1st March 1872, and dated the 15th November 1871.
PROVISIONAL SPECIFICATION left by the said Alexander Horace
Brandon at the Office of the Commissioners of Patents, with
his Petition, on the 15th November 1871.
I, ALEXANDER HORACE BRANDON, of 13, Rue Gaillon, Paris, France,
Civil Engineer, do hereby declare the nature of the said Invention for
"AN IMPROVED CONSTRUCTION AND ARRANGEMENT OF ORGAN PIPES AND THE VALVES
AND AIR PASSAGES THEREOF FOR PARLOR, REED, AND KEY-BOARD MUSICAL INSTRU-
MENTS," to be as follows:-
The Invention relates to an improved construction and arrangement of
organ pipes and the valves and air passages thereof for parlour, reed, and

page_text: key-board musical instruments, the improvements having particular
reference to the construction and arrangement of a series of pipes.
Heretofore the pipes used in parlour organs or contained within a small
portable case have been insolated or independent one from another, so
that in applying or removing them they are handled and fastened in
place or detached from place one by one, and for their proper relative
disposition and proper security they require great care and skilful
manipulation. In addition to this, each pipe so made has to be perfect
in itself as to construction, involving cost in material and in good
workmanship.
In this Invention these defects are obviated by assembling the pipes
together in one series, connected and inseparable, so that all are applied
and removed as one piece and no one is detachable from the others. This
result is attained by making a pipe trunk or case, or an assemblage of
pipes formed of two boards, preferably placed at uniform distances apart
to permit sufficient space in each tube, with a series of partitions at
respective distances apart as are required to form the several pipes, the
whole properly fastened together and forming in effect a series of tubular
bores through a solid piece. To the pipe case, trunk, or box so made is
fastened the valve box, through which the air passes to the pipes, the
respective valves being operated by the respective keys of the key board,
and surmounting the pipe box and covering all the pipes or pipe passages
is a hinged valve, by adjustment of which the pipes are readily kept in
tune with the reeds.
The pipe box or trunk containing the series of pipes or pipe passages
and made as one removeable piece, the connection and arrangement with
respect thereto of the valve and wind box, the arrangement of the
tuning valve to cover the series of pipe passages, and the position of
the whole within the organ case constitute the principal features of the
Invention.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Alexander Horace Brandon in the Great Seal
Patent Office on the 11th May 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALEXANDER
HORACE BRANDON, of 13, Rue Gaillon, Paris, France, Civil Engineer, 3
send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of November, in the
year of our Lord One thousand eight hundred and seventy-one, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Alexander Horace Brandon, Her special
licence that I, the said Alexander Horace Brandon, my executors,
dministrators, and assigns, or such others as I, the said Alexander
Horace Brandon, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times
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 "AN IMPROVED CONSTRUCTION AND ARRANGEMENT OF ORGAN PIPES AND THE
VALVES AND AIR PASSAGES THEREOF FOR PARLOR, REED, AND KEY-BOARD MUSICAL
INSTRUMENTS," a communication by Carl Fogelberg, a person resident at
Boston, Massachusetts, United States of America, upon the condition
(amongst others) that I, the said Alexander Horace Brandon, 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 Alexander Horace Brandon, do
hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the Drawing
hereunto annexed and to the letters and figures marked thereon (that
is to say):
:-
The Drawings represent a parlor or reed organ case and the mechanism
directly connected therewith, embodying the Invention.
Fig. 1 is a vertical cross section of the organ; Fig. 2 is a rear eleva-
tion of the pipe case and adjacent connections; Fig. 3 is a sectional
elevation of the pipe valve box, shewing the mechanism that operates
the valve which controls entrance of air to the valve box; Fig. 4 is an
end elevation, shewing the mechanism that operates the tuning valve
which covers the pipes; Fig. 5 shews one end of the pipe trunk in
horizontal section.

page_text: and the valve of the pipe corresponding therewith. Wind is admitted to
the valve and wind chest a from the bellows through a pipe z, connecting
at one end with the bellows chamber, and at the other end with the
wind and valve chest, the pipe opening into one end of the chest and
passage from the pipe to the chest being controlled by a valve aª
operated by a "stop" 6 at the front of the instrument, and a suitable
lever connection between the stop and the valve stem.
When the pipes are to be brought into action the stop is drawn out,
opening the valve a³, and when the melodion reeds are to be operated
without the pipe the valve is closed by throwing in the stop, there being
then no admission of air into the valve box.
The top of the pipe case or trunk is made horizontal, and is covered
by the hinged valve c*, said valve covering a series of passages d (one
to each pipe) leading from the pipes, as seen at Fig. 1.
This valve is connected by a suitable lever mechanism with a screw e³,
as shown in Fig. 4, by means of which screw the valve can be raised or
lowered and set in open or closed position or adjusted in open position, as
may be required.
In combining the metallic reeds and the pipes, the variation in
weather and temperature affect them relatively, so that they do not
keep in tune, the change being mostly in the pipe tones. By placing the
valve as shewn and by means of it controlling the openings at the tops
of all of the pipes the valve may be readily raised or lowered and the pipes
be at any time brought into tune with the reeds by simple adjustment
of the valves.
It will be observed that the pipe case is placed with the openings near
to the top thereof, bringing the valve box nearly into a plane with the
key board or so that the valve levers may be placed in position to be
readily operated by the keys, bringing the whole of the reeds, reed
valves, pipes, pipe valves, and reed valve, and pipe valve operating
mechanism into a compact and accessible position.
The pipe case and the mechanism directly connected therewith may
be constructed in a similar manner for other than melodeon reed musical
instruments, but the improvements are particularly designed for this
class of instruments.
