I, LOUIS EMILE JEROME THIBOUVILLE of 68-70 Rue Réaumur Paris in the
Republic of France Musical Instrument maker do hereby declare the nature of this
invention to be as follows:-
:-
My invention relates to musical instruments of the kind in which a travelling
perforated card acts by its perforations on valves causing notes to sound determined
in pitch and duration by the positions and lengths of the acting perforations. I will
describe my improvements referring to the accompanying drawings. Fig. 1 is a side
view of an instrument according to my invention with part of the case broken away
to shew certain internal parts. Fig. 2 is a longitudinal section. Fig. 3 is an end view.
Fig. 4 is a plan. Fig. 5 is a part end elevation with the front removed. Fig. 6 is an
end view to an enlarged scale shewing the connection of one of the valves to its lever.
Fig. 7 is a plan of one of the cards. The case A contains in its upper part the valve
mechanism, and in its lower part the bellows which are of ordinary construction. At
each end B of the case there is a horizontal slit C through which the cards G pass
from a shelf D at the one end to a pocket E at the other end. F is the sound board
on which are fixed reeds a below sonorous cavities beach cavity being covered by a
valve d pressed down by a spring e. Each of the valves e is connected by a hooked
rod (Fig. 6) to the end of a lever pivotted at g on a cross frame and pressed
down by a spring k. Each of the levers is connected by a tracker j to a lever i
having a slot engaged on a cross wire i¹ forming a pivot. The noses of the levers i
bear against the underside of the travelling card G immediately under a grooved
roller m, but when a hole in the card presents itself to one of the noses, it ascends,
opening one of the valves d and causing the corresponding note to sound. The card
is drawn onwards between two feed rollers m³ m², the lower one m² of which is caused
to revolve by turning a winch handle H on its axis. This axis has cranks n working
the bellows arms n¹. For the purpose of introducing a card, a lever L is moved to
depress simultaneously all the noses ³, to raise the grooved roller m and the upper
feed roller m¹. This lever L is fixed on a spindler which extends across the instru-
ment and is widened out as shewn at r Fig. 2. On raising the lever L the widened

page_text: part pushes down all the levers i and also on each side of the case a lever p (Fig. 1.)
pivotted at q thereby raising the bearings 91 of the upper feed roller m² and also
raising a lever p¹ which is pivotted at 9' and which raises the bearings of the grooved
roller m.
To facilitate access to the reeds and valves for cleansing or repair, the
sound board F carrying them is fitted to slide in guides o (Fig. 5) fixed on the cover c
of the wind chest. On removing the front panel K (Fig. 2) and taking hold of a
crank handle o¹ the sound board can be slid out, and after cleansing or repair can
be slid in again each of the valve hooks f¹ engaging on the end of its appropriate
.ever f. In order to give a swell effect when desired, a part or flaps of the cover of
the case at each side is hinged at s¹ and kept closed by springs but can be more or
less opened when desired by a lever t working a cross spindle t¹ on which are arms u
that hear under the flaps s.
When it is desired to play a piece repeatedly, the first and last of the cards G may
be provided with hooks (Fig. 7) so that they can be attached to one another, thus
forming an endless travelling sheet.

Improvements in Automatic Musical Instruments.
1, LOUIS EMILE JEROME THIBOUVILLE of 68-70 Rue Réaumur, Paris in the
Republic of France, Musical Instrument Maker do hereby declare the nature of this
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
My invention relates to musical instruments of the kind in which a travelling
perforated card acts by its perforations on valves, causing notes to sound determined
in pitch and duration by the positions and lengths of the acting perforations. I will
describe my improvements referring to the accompanying drawings. Fig. 1 is a side
view of an instrument according to my invention with part of the case broken away
to shew certain internal parts. Fig. 2 is a longitudinal section. Fig. 3 is an end view.
Fig. 4 is a plan. Fig. 5 is a part end elevation with the front removed. Fig. 6 is an
end view to an enlarged scale shewing the connection of one of the valves to its lever.
Fig. 7 is a plan of one of the cards. The case A contains in its lower part the bellows
which are of ordinary construction. At each end B of the case there is a horizontal
slit C and a through which the cards G pass from a shelf D at the one end to a
pocket E at the other end. F is the sound board mounted on the table C and on
which are fixed reeds a below sonorous cavities b each cavity being covered by a
valve d pressed down by a spring e. Each of the valves d is connected by a hooked
rod f1 (Fig. 6) to the end of a lever of pivotted at g on a cross frame h and pressed
down by a spring k. Each of the levers fis connected by a packer j to a lever i
having a slot engaged on a cross wire i forming a pivot. The beaks of the levers i
bear against the underside of the travelling card G immediately under a grooved
roller m, but when a hole in the card presents itself to one of the beaks, it ascends,
allowing one of the valves d to be opened by lever and causing the corresponding
note to sound by the passage of air from the bellows through the reed. The card is
drawn onwards between two feed rollers m¹ m³, the lower one m² of which is caused
to revolve by turning a winch handle H on its axis. This axis has cranks n working
the bellows arms n¹.
For facilitating the cleaning and repair of the sound board F this is formed like a
drawer sliding in grooves o Figs. 4 and 5. When it is to be drawn out, it is only
necessary to remove a panel K held by two studs on the casing, when the sound
board can be drawn out by the iron rod o¹ which ordinarily holds in place.
Each valved being connected to its lever f by a simple hook fembracing its end
as shewn at Fig. 6, there is nothing to prevent their ready detachment on the
withdrawal of the sound board.
The mechanism for lowering the beaks of the levers i at the same time that it
raises the grooved cylinder and upper driving roller m³, is actuated by a lever L.
The grooved cylinder m and the roller m¹ rest with their extended axes upon two
tumbler levers p p pivotted at q. The bearings of the axes are always held down by

page_text: blade springs q; an axis r which passes over the levers i is provided with a flattened
part which lowers the levers i when the lever L is moved from left to right and
which at the same time raises the grooved cylinder and upper driving roller. By
this movement the flat part of r is made push the levers i downwards and the tumbler
levers P P lift. the grooved cylinder and upper driving roller, thus permitting of the
ready insertion of the music card. On moving lever L in the contrary direction the
springs bring the cylinder and roller back to their original position.
In order to obtain a swell effect I arrange two shutters or flaps S that are opened
more or less when required. These flaps S are jointed to the cover by hinges S1 and
are kept closed by springs S; for opening them a lever t is pressed upon which has
on its axis t¹ two tappets u that raise the flaps more or less, according as the lever t is
moved more or less.
When it is desired to play a piece repeatedly without interruption, I provide the
music cards with a connection x Fig. 7 by which the two ends are connected together,
so as to form an endless band that can pass continuously through the instrument.
It will be evident that the organ may be arranged to work either by air pressure or
by exhaust by suitably arranging the reeds in a well known manner.
It sometimes happens that when the music cards are new, the joints being stiff, it
does not fold up in a proper manner on leaving the instruments.
For obviating this inconvenience I provide on the end of the box a guard for
bending the cards as they issue, consisting simply of a wire frame y hanging freely
from hinges at the end where the driving rollers are situated, as shewn at Figs. 1, 2,
4 and 8. This wire guard bears with its weight upon the issuing card and thereby
obliges this to bend properly at the joints. When a card passes out, it raises the
guard until the entire card has issued through the opening a, whereupon it will be
bent downwards by the guard.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what
I claim is :-
1. In automatic musical instruments the use, for working the reed valves, of double
ended levers acted upon by springs so as to open the valves when the beaks connected
to the said levers pass through the perforations of the travelling music cards, sub-
stantially as herein described.
2. Constructing the sound board carrying the reeds and valves of an automatic
musical instrument so as to be capable of being slid in and out of the instrument, in
order to facilitate cleaning and repairs, substantially as described.
3. In combination with the sliding sound board referred to in the preceding claim,
effecting the connection of the reed-valves with their levers by a hook or loop into and
out of which the levers can freely slide, substantially as herein described.
4. In combination with automatic musical instruments worked by folding music
cards constructed as herein described, the use of pivotted wire guards for forcing
the cards to fold together properly as they issue from the instrument, substantially as
herein described.
