1, HERBERT JOHN HADDAN of 67 Strand, in the County of Middlesex, Civil
Engineer, do, hereby declare the nature of this invention to be as follows:-
This invention has for its object the arrangement of musical bells in accordeons
aristons, herophons or other like wind instruments, so that by the opening of each flap,
a simultaneous stroke is given to a bell corresponding in tone to that of its respectivo
flap.
This purpose is attained by providing each flap with a hammer, which, when the
flap is opened, strikes against the respective bell of a peal of bells arranged before the
flaps, and thus produces the corresponding bell sound. The hammer is suitably secured
to the flap by means of a thin wire or a fine spring. The hammer, instead of being
fastened direct to the flap may also be connected with the key or the key board of
the respective flap.
To allow the bells to be engaged or disengaged at any time whilst playing, they are
so arranged in the accordeon, that the player can lift or lower the whole of the bells
by hand pressure, so as to bring them out of striking distance of the hammers, so that
they are not sounded, when the flaps are opened or on the other hand are brought
within reach of the hammers.
In the ariston, the disengagement of the hells is produced by a lever with a
displaceable arm or the like.
With the herophon, in which the music mechanism turns in a circle, the bells are
carried by a horizontal ring fixed to the frame or casing of the instrument. The bells
are supported by the upper rim of this ring and turn with the music mechanism,
so that the ring does not change its relative position to the flaps and the hammers
secured thereto. When the ring however is raised, the bells are simultaneously also
raised and are thereby brought out of reach with the hammers, until the ring is again
owered. This raising and lowering of the ring may be produced by a set screw.

Improvements in Musical Bell-mechanism for Musical Wind
Instruments.
I, HERBERT JOHN HADDAN of 67 Strand, in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention, a communication from abroad
by Johann Werner of Hamburg, Germany, Musical Instrument Maker, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—
This invention has for its object the arrangement of a series of bells in accordeons,
aristons herophons or other like wind instruments so that by the opening of each flap
a simultaneous stroke is given to a hell, corresponding in tone to that of its respective.
flap.
This purpose is attained by providing each flap with a hammer, which, when the flap
is opened, strikes against the respective bell of the peal of bells arranged before the
flaps and thus produces the corresponding bell sound. The hammer is suitably secured
to the flap by means of a thin wire or fine spring. The hammer, instead of being
fastened direct to the flap, may also be connected with the key or the key-lever of the
respective flap.
Referring to the accompanying drawings, Figs. 1, 2 and 3 show the arrangement
in combination with the lid of an accordeon, the bellows and the bottom being omitted.
Figs. 4 and show the arrangement in combination with an ariston, and Figs. 6 and 7
likewise in combination with the herophon.
Referring to sheets 1 and 2, the cross section Fig. 1 shows the flap K in its closed
position, Fig. 2 in opened position, and the respective key T pressed onto the hand
board H. Fig. 3 is a plan of the lid or cover, seen from above, on a smaller scale than
Figs. 1 and 2.
The bell work G consists of a series of single bells g g'g, which, fastened on a rod s
are so arranged over the flaps, that the different bells correspond in tone with the
respective tones of the flaps situated thereunder; by the arms mm the bell work is
revolvably lodged on the hand board H.
A cross bar e connecting the two arms m
and m and which can, at any time be seized by the player with a finger of his right
hand, allows the bells to be lowered or raised into the position indicated in Fig. 2 by
dotted lines.
When the bells are lowered, a stroke of the hammer o on the bell situated thereover
is effected by pressing down the key and opening the respective flap K. When the
bells are raised (as indicated by dotted lines in Fig. 2) no sounding thereof takes
place, when opening the flap, since the hammer can no longer reach the respective
bell.
With the ariston, which is represented as far as it is required for this purpose, by
Figs. 4 and 5, the flaps are contained in the casing B and are operated by turning the
perforated music sheet R. The bells G are again arranged above the flaps K. o are

page_text: the hammers fastened by means of a thin wire arm to the flaps. The bell-work is
hinged revolvably at the casing by means of the arms mm and is adapted to be
displaced by the fork p with the rod v fastened thereto and extending outwardly. In
the position indicated by dotted lines in Fig. 4, the bells are withdrawn from reach of
the hammers.
With the herophon, in which the music sheet R is stationary and the mechanism
revolves circularly, the bell work G is hinged to the rotating part by the arm m and
is supported by a ring displaceable upward and downward. When the ring is
lowered, the hammers o reach the bells, when the flaps are opened. When the ring is
raised, the bells are, as shown by Fig. 6, removed out of reach of the hammers. The
ring may be guided on one side on the stationary rod by means of arms a a, so as
to slide thereon, the rod p leading outward, being adapted to raise or lower the said
ring. On the opposite side the ring is guided by arm on the stationary rod y', and
a spring carries this end of the ring. By pressing down the knob of the rod " the
bell work is brought into action.
!!
Having now particularly described and ascertained the nature of this invention, and
in what manner the same is to be performed, I declare that what I claim is:
1) In instruments having flaps K, hammers arranged on said flaps in combination
with a displaceable series of bells adapted to be brought in reach of the said hammers
and withdrawn substantially as and for the purpose set forth.
2) In accordeons the arrangement of the bells revolvably on the hand board H
and the combination therewith of the rod e, substantially as and for the purpose set
forth.
3) In aristons, the arrangement of the bells with rod e for operating the said bells
substantially as and for the purpose set forth.
4) In herophons, the arrangement of the bells in combination with a ring
displaceable upward and downward and supporting the said bells, substantially as and
for the purpose set forth.
