Organs, and Thomas Isaac Isaacs, of No. 35, Archer Street, in
the said County, Foroman to the said William George Kindred
PROVISIONAL SPECIFICATION left by the said William George Kindred
Breavington and Thomas Isaac Isaacs at the Office of the Commis-
sioners of Patents, with their Petition, on the 30th April 1872.
We, WILLIAM GEORGE KINDRED BREAVINGTON, of No. 309, Regent
Street, in the County of Middlesex, Manufacturer of Reed Organs, and
THOMAS ISAAC ISAACS, of No. 35, Archer Street, in the said County,
Foreman to the said William George Kindred Breavington, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN REED
ORGANS," to be as follows:-
Our Invention relates to the class of organs which are known as
"American organs," and in which reeds are used.

page_text: Our Invention consists, firstly, in fixing in what is known as the
reverberating sound box" and under the ordinary sound board thereof an
additional sound board, which has holes for the passage of wind from
the lower part of the said box to the said ordinary sound board, and is
fixed at a suitable inclination thereto so that the space between the two
boards will be greatest under the bass reeds and will diminish toward the
treble reeds. By this arrangement we improve the tone and increase the
power of the organ.
Our Invention further consists in constructing at the back of the
reverberating sound box aforesaid a shallower reverberating sound box, 1
over which latter the solo reed board is placed, which shallower sound
box communicates with the first named box by means of suitable air
passages. The mechanism for coupling the action of the two sound
boards so as to admit of playing on either or both sets of reeds by means
of the same keys is essentially the same as that used for analogous 1
purposes in reed organs of the ordinary construction. The advantages
of this arrangement are its simplicity and the "brighter" tone produced
in the solo by means of the shallow sound box described.
Our Invention relates further to reed organs in which horizontal
bellows are used, and consists in the application to such bellows of the 2
automatic swell action hitherto used only in connection with vertical
bellows.
In applying the said action to horizontal bellows we dispense with the
bell-crank lever which communicates the motion of the bellows to the
swell levers, and substitute for the said lever a straight lever of the first 2
order, one end of which is acted upon by the bellows through the
"sticker," the other end being connected to the "pull down " which
works the swell levers.

said William George Kindred Breavington, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of April, in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said William George Kindred Breavington and
Thomas Isaac Isaacs, Her special license that we, the said William
George Kindred Breavington and Thomas Isaac Isaacs, our executors,
administrators, and assigns, or such others as we, the said William
George Kindred Breavington and Thomas Isaac Isaacs, our 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 "IMPROVEMENTS IN
"REED ORGANS," upon the condition (amongst others) that we, the said
William George Kindred Breavington and Thomas Isaac Isaacs, our
executors or administrators, by an instrument in writing under our or
their hands and seals, or under the hand and seal of one of us or them,.
should particularly describe and ascertain the nature of the said Inven⚫
tion, 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 William George Kindred Breavington,
on behalf of myself and the said Thomas Isaac Isaacs, 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 thereof, that is to say :-
Our Invention relates to the class of organs which are known as
"American organs," and in which free reeds vibrating in resonant air
chambers are used.
Our Invention consists, firstly in fixing in what is known as the
' reverberating sound box," and under the ordinary sound board thereof,
an additional sound board which has holes for the passage of the wind
from the upper to the lower part of the said box, and is fixed at a
suitable inclination to the ordinary sound board, so that the space

page_text: between the two boards will be greatest under the bass reeds and will
diminish toward the treble reeds. By this arrangement we improve the
tone and increase the power of the organ,
Our Invention further consists in constructing at the back of the
reverberating sound box aforesaid a shallower sound box, over which 5
latter the solo reed block is placed, which shallower sound box communi-
cates with the first named box by means of suitable air passages. Tho
mechanism for coupling the action of the two sound boards so as to
admit of playing on either or both sets of reeds by means of the same
keys is essentially the same as that used for an analogous purpose 1
in the reed organs known as the "Mason and Hamlin organs." The
advantages of this arrangement are its simplicity and the "brighter" tone
produced in the solo by means of the shallow sound box and air
passages arranged relatively to the ordinary sound box as described.
Our Invention relates further to recd organs in which horizontal 1
bellows are used, and consists in the application to such bellows of the
automatic swell action hitherto used only in connection with vertical
bellows.
In applying the said action to horizontal bellows we dispense with
the bell crank lever which in organs constructed with vertical bellows 2
communicates the motion of the bellows to the swell levers, and wo
substitute for the said lever a straight lever of the first order, one end
of which is acted upon by the bellows through the "sticker," the other
end being connected to the pull down which works the swell levers.
Having now described the nature of our Invention, we will proceed to a
describe the manner in which the same is to be performed, reference
being had to the accompanying Drawings, and to the letters and figures
marked thereon.
Figure 1 is a transverse vertical section of the principal parts of an
organ constructed according to our Invention, such parts as are not a
necessary to the description of our said Invention being omitted; and
Figure 2 is a longitudinal vertical section (taken on the line X, X,
Figure 1) of the reverberating sound box of the said organ, and the
additional sound board herein-before described. The same letters of
reference indicate the same parts in both Figures.
A, A, are the keys, and a' are stickers carried by the said keys, which
depress stickers a² and open the pallets b'; a³ are other stickers which

page_text: work the octave couplers a'; B is the reverberating sound, box, and 6º
is the ordinary sound board thereof; B₁ is the additional sound board,
which is fixed at an inclination, as shown; 6³, &, are holes for the
passage of the wind from the upper to the lower part of the said box;
and b', 6ª, are holes communicating with the wind trunk C, the lower
end of which communicates with the bellows D', D³, which are worked
in the usual manner; E is the shallow reverberating sound box, in
which the reed block F containing the solo and sub-bass reeds is fixed,
which box we arrange at the back of the sound box B, as shown; ƒ¹is
the box which is fixed over the sub-bass reeds and stickers; e' are the
pallets of the said reeds; e³ are holes which communicate with an air
passage or trunk G, which is constructed at the angle formed by the
junction of the sound boxes B and E, and which extends the whole
length of the said boxes. From the trunk G the wind passes through a
series of coincident holes or air passages g, b³, to the sound box B,
and
thence to the trunk O; a³ are stickers which transmit motion from the
keys through the solo, and sub-bass couplers f* to the stickers f, which
act on the pallets e¹. The couplers a' and f³ consist of cranked or bent
wires, the arrangement of which relatively to the stickers is similar to
that of the couplers used in the organs known as the "Mason and
Hamlin" organs, and the said couplers a' and f' are thrown into and
, out of gear as required by means of sliding wedge actions as in those
organs. H is the lever which transmits motion from the bellows to the
automatic swell levers; h' is the fulcrum of the said lever; and h³ is a
sticker, the lower end of which is affixed to a lug d on the bellows D',
the other end being connected to the lever H; ³ is the "pull-down," the
upper end of which is connected in the usual manner to the swell
levers *, * (indicated by dotted lines), which open the flaps h³, h³, the
lower end being connected to the lever H. This arrangement admits
of the application of the automatic swell to organs having horizontal

page_text: Secondly. The relative arrangement of the ordinary reverberating
sound box and the shallower reverberating sound box herein-before
described and illustrated in Figure 1 of the accompanying Drawings;
that is to say, fixing the said shallower reverberating sound box to the
back of the said ordinary reverberating sound box and at the upper part
thereof, and making at the angle formed by the junction of the two
boxes an air trunk or passage with holes for the passage of the wind
from the said shallower sound box to the said ordinary sound box as
described.
Thirdly.Adapting the automatic swell action to reed organs having
horizontal bellows as herein-before described and illustrated in Figure 1
of the accompanying Drawings, that is to say, applying to such organs
a lever of the first order, one end of which is connected to the sticker of
the bellows, and the other end to the "pull-down" of the swell levers as
and for the purpose described.
In witness whereof, I, the said William George Kindred Breaving-
ton, have hereunto set my hand and seal, this Twenty-ninth day
of October, in the year of our Lord One thousand eight hundred
and seventy-two..
