TECHNICAL FIELD OF THE FINDING
[0001] The present invention relates to a tuning device for pipe musical instruments, such
as an organ or a wind musical instrument.
STATE OF THE PRIOR ART
[0002] In the field of pipe musical instruments, in particular organs, it is necessary to
be able to tune, in an accurate and enduring manner, both new and old musical instruments;
in the latter case, during restoration, respecting the original characteristics of
the instruments themselves.
[0003] The currently used tuning modes are the following.
[0004] The first tuning mode, of conventional type, is termed "cylindrical tuning" and is
executed by making a cylindrical cut of the terminal part of the pipes up to the attainment
of the desired height. As appears clear, this is a mode for tuning of manual type,
which requires highly specialized manual ability and very long execution times. By
means of this conventional technique, most of the time the desired frequency is approached,
which is then improved by means of the use of "correction pegs", i.e. cones that abut
against the top of the pipe in a manual but delicate manner, in order to enlarge or
narrow the terminal part of the pipe itself. This type of tuning does not allow making
cuts of size smaller than about 1 mm, and therefore it is hard to reach the perfect
pipe frequency.
[0005] In addition, once such tuning is made, it cannot be modified: this means that the
other musical instruments, that may play together with the organ in question, must
be adapted to the pitch and to the temperament of the tuned organ, while the opposite
is not possible.
[0006] In addition, this type of tuning of conventional type requires, during restoration,
that the terminal part of the pipe be tampered with. Nevertheless the new international
directives for organ restoration, and especially for the restoration of antique organs,
advise against such procedure since it is deemed irreversible, as it applies modifications
to the original pipes that alter the characteristics originally present in the organ;
such modifications are irreversible, since once the conventional tuning has been actuated,
it is not possible to use further restoration techniques that better reflect the philology
of the instrument itself.
[0007] In addition, since the correction/adjustment pegs are abutted against the top of
the pipe in proximity to the cut, in order to carry out the fixing thereof, it is
possible that the pipe will break, especially in the case of modern pipes, due to
the specific metal alloy used for the attainment thereof.
[0008] A further mode for tuning the pipe musical instruments, such as organs, is the so-called
"tear tuning", which however is not very stable. According to such system, a tear
is executed in the upper part of the pipe, in order to adjust the frequency thereof.
Nevertheless, this is a very invasive and destructive technique, not permitted by
restoration procedures of antique organs, since the cylindrical walls of the pipe
are enlarged until the desired tuning is attained.
[0009] A further tuning mode, quite unscientific and rushed, consists of manually pressing
the central part of the pipe, determining a tuning however with extremely poor stability.
There is also the "window tuning" mode, carried out in the organs starting from the
1900s, in which an overturned U-shaped incision is made on the top of the pipe and
the tongue of material - within the overturned U - is curled until the window has
size suitable for tuning the pipe frequency. Also in this case, the pipe to be tuned
must be made of a rigid material, capable of supporting the incision, and this is
an irreversible procedure. In addition, the pipe may result unstable after such tuning
has been made.
[0010] In addition, the above-described known methods do not allow varying the frequency
of the pipe by much: for example, with the first method it is possible to vary the
pipe to be tuned by only 2-3 hundredths of frequency. The patent No.
US154022 discloses a pianoforte with an organ-pipe attachment attached thereto. In particular,
it discloses a section of a metal pipe D', with its tuning tube P' and a thumb-screw
o'. the thumb-screw o' is welded to the pipe D' and also to the tuning tube P'.
[0011] The present invention, as is better described hereinbelow, resolves the above-lamented
drawbacks.
OBJECTS OF THE INVENTION
[0012] The technical task of the present invention is therefore to improve the state of
the prior art.
[0013] In the scope of such technical task, one object of the present invention is to obtain
a tuning device that allows tuning pipe musical instruments whether they are of new
production or antique.
[0014] A further object of the present invention consists of obtaining a tuning device that
allows an enduring and precise tuning.
[0015] A still further object of the present invention consists of obtaining a tuning device
that allows varying the tuning and which is reversible.
[0016] A further object of the present invention consists of obtaining a tuning device that
allows considerably reducing the times necessary for the complete tuning of a pipe
musical instrument.
[0017] This task and this object are attained by the tuning device according to the enclosed
claim 1 and the corresponding method claim 10.
[0018] Further advantageous characteristics are described in the dependent claims.

EMBODIMENTS OF THE INVENTION
[0020] With reference to the enclosed figures, reference number 1 indicates a tuning device
for a pipe musical instrument, such as a pipe organ or wind musical instrument, such
as a trumpet, a flute etc. According to the present invention, the tuning device allows,
as will be seen more clearly below, varying the pitch and the temperament of the musical
instrument that is tuned, such that the same can be adapted to the desired historical
repertoire and hence play, both with musical instruments with setting that is antique
with respect to current setting, and with modern instruments.
[0021] In addition, as will be appreciated in the following description, the time for tuning
a register, due to the tuning device 1 according to the present invention, is reduced
to 10 minutes, instead of the hour required with the conventional procedure.
[0022] In addition, due to the tuning device 1 according to the present invention, it is
possible to precisely - and differently with respect to each other - tune different
registers of a same musical instrument or organ, for example when the same are positioned
in different places of a same building, and hence they can be subjected to different
temperatures.
[0023] Finally, the tuning device according to the present invention can also be used on
pipes to which a conventional type tuning has been carried out, for example pipes
in which the abovementioned U-shaped window has been obtained.
[0024] The tuning device 1 according to the present invention can be applied to each pipe
C or resonator, in other words the upper or terminal part of the pipe of an organ,
present in a pipe musical instrument such as an organ or a wind musical instrument.
[0025] In particular, with regard to the organs, they can be tuned by acting on the upper
or terminal portion of the pipes.
[0026] In particular, in one version of the invention, the tuning device 1 according to
the present invention is applicable to the upper or terminal part of each pipe C of
an organ, at its upper or terminal end. Such upper or terminal end is the end for
the outflow of at least part of the air that determines the frequency in relation
to the volume of the resonator itself.
[0027] Preferably, such tuning device is applicable to the metal cylindrical pipes, both
open and shut, at the upper or terminal part of the respective pipe C or resonator,
but it can be applied to musical instruments provided with pipes of any type, without
departing from the protective scope of the present invention.
[0028] The tuning device, as it is visible in figure 5, can also be applied to the conical
pipes, both open and shut, always at the upper or terminal part of the respective
pipe C or resonator.
[0029] In one version of the invention, the pipes are open at least at the top, possibly
of labial type.
[0030] In some cylindrical reed pipes, the tuning device according to the present invention
can also be used for precisely reaching the note or frequency. Indeed, sometimes,
by means of the conventional tuning, the attainment of such precision requires a lot
of time. Hereinbelow in the present description, the terms "pipe" and "resonator"
will be used indiscriminately, considering the "resonator" to be the upper or terminal
part or the "body", or the length of the pipe itself.
[0031] The tuning device 1 comprises a support collar 2, fixed during use, mountable on
the resonator or on the upper or terminal part of the pipe C at a certain distance
from the free and/or terminal and/or upper end thereof.
[0032] The free and/or terminal and/or upper end of the pipe C or of the resonator is the
end of the pipe C from which at least part of the vibrating air exits, such air generated
by the musical instrument or in any case necessary for the operation thereof.
[0033] This positioning is very important since, given that the tuning device 1 is positioned
at the free and/or terminal and/or upper end of the pipe C, such tuning device 1 potentially
has a considerable opportunity to slide and hence tune, as will be better indicated
hereinbelow.
[0034] Otherwise, for some musical instruments such as the saxophone or clarinet, a device
may be provided capable of adjusting the distance between two components of the instrument
itself, for example between the mouth (or mouthpiece) and mouth (or neck) of a saxophone.
In such case, however, the possibility of spacing such components, and hence adjusting
the tuning thereof, is limited to the extent in which such components can be separated
or moved away from each other while remaining assembled for instrument operation.
In addition, such device is generally associated with the portion of the instrument
by means of which the air is introduced or conveyed, in other words with the portion
where the sound is "born". In this manner, the applied device adjusts the intonation
of all the notes of the instrument, preventing a note-by-note adjustment, as is instead
possible with the tuning device according to the present invention.
[0035] Instead, in the present invention, the tuning device 1 is positioned in the part
opposite that where the air is introduced or conveyed: indeed it is positioned in
the upper part of the pipe C of an organ, hence at the portion of the instrument from
which at least part of the air exits or from which the sound exits, and in any case
at the end of the path that the air makes within the instrument.
[0036] In addition to the abovementioned advantage, such positioning also allows the tuning
device according to the present invention to be mounted/dismantled from the pipe C
with great ease, without requiring the disassembly of other components which form
the instrument in order to allow the positioning of the tuning instrument, and hence
without requiring the reassembly of such components for instrument operation.
[0037] With regard to an organ, each pipe is substantially made of a single piece or of
an inseparable portion, and hence it is not possible to position the tuning device
1 between two different portions or parts of the pipe (there is a single portion that
attains the pipe itself). Therefore, in the case of the organ, the preferred portion
of the tuning device 1 is at the end of the pipe, at the free and/or upper end or
in any case in the end portion of the pipe C.
[0038] Finally, as will be clarified hereinbelow, the tuning device 1 according to the present
invention does not determine the relative movement of two components of the pipe of
the musical instrument or of the organ, but rather the relative movement of the at
least two components of the tuning device, while the pipe C of the instrument remains
substantially undisturbed by the tuning device 1 itself.
[0039] The support collar 2 has an annular form delimiting a region with section substantially
corresponding to the transverse size of the resonator of the pipe C, in particular
of the end portion thereof, and is stably fixable thereto in any suitable manner.
[0040] According to the present invention, the support collar 2 comprises a side wall 3
extending over a given section h along the longitudinal symmetry axis X of the respective
pipe C.
[0041] Such side wall 3 or support collar 2 has a substantially C-shaped cross-section configuration.
In addition, it comprises two ears or slots 6, placed at the respective ends of the
substantially C-shaped cross section of the side wall 3 and externally rising upward
from the side wall itself.
[0042] The tuning device 1 according to the present invention also comprises locking means
4, of removable or fixed type, for example clamps or welding, capable of fixing the
two ears or slots 6 together, and hence anchoring the support collar 2 to the resonator
of the respective pipe C in a preset position.
[0043] One detail of the support collar 2, of the ears or slots 6 and of the locking means
4 is illustrated in figure 3.
[0044] With one such configuration, the support collar 2 can be easily mounted, either fixed
or removable on the respective pipe C, as will be better described hereinbelow.
[0045] The tuning device 1 according to the present invention also comprises a tubular portion
7, movable during use, provided for being slidably mounted, as will be better described
hereinbelow, on the resonator of the respective pipe, at the free and/or upper and/or
terminal end thereof.
[0046] More particularly, the tubular portion 7 delimits a cross section substantially corresponding
to the transverse size of the resonator of the pipe C to which it is applied during
use.
[0047] In particular, the tubular portion 7 does not have to be adherent to the pipe on
which it is mounted, but it will suffice that it can slide thereon without generating
friction, in order to be able to adjust the sliding and hence the final tuning of
the instrument.
[0048] As is obvious, the tubular portion 7 has different size depending on the transverse
size of the pipe C on which it must be mounted, in relation to the diameter, frequency
and length of the pipe itself.
[0049] According to the invention, both the support collar 2 and the tubular portion 7 are
positioned outside the pipe C.
[0050] The tubular portion 7 has a side wall 9 extending over a given section H along the
longitudinal symmetry axis X of the pipe C.
[0051] According to a preferred embodiment of the invention, the extension H of the side
wall 9 of the cylindrical portion 7 measures about a third or a fourth of the length
of the resonator of the respective pipe C.
[0052] The internal volume of the resonator is, as is known, directly proportional to the
value of the sound frequency that can be emitted by the pipe C itself.
[0053] The height h of the side wall 3 of the support collar 2 measures, for example, a
quarter of the height H of the tubular portion 7. In one version of the invention,
the height h can have a size comprised between 0.5 cm and 2 cm.
[0054] The tuning device 1 according to the present invention provides for means 8 for adjusting
the distance between the support collar 2 and the tubular portion 7. These are provided
mounted between the support collar 2 and the tubular portion 7 and during use intended
to move such tubular portion 7 along the resonator of the pipe C.
[0055] In such a manner, the tubular portion 7 can project with respect to the free and/or
upper and/or terminal end of the resonator by a certain sufficient amount such that
the frequency that can be emitted during use by the pipe itself corresponds to a desired
value.
[0056] According to the invention, the tuning device 1 comprises engagement means 8a, 8b,
respectively mounted on the support collar 2 and on the tubular portion 7 and provided
for engaging the adjustment means 8.
[0057] In the following description and in the enclosed drawings, two engagement means are
represented, but the same can also be present in a greater number, especially those
present at the tubular portion 7, as illustrated in figure 6, if the pipe C or the
resonator is of larger size or if multiple tubular portions 7 are present.
[0058] An important characteristic of the engagement means, as will be better indicated
hereinbelow, is that the same are calibrated and aligned, in a manner so as to allow
the sliding of the adjustment means 8 at their interior and hence the adjustment of
the position of the tubular portion 7 with respect to the support collar 2.
[0059] In the support collar 2, in a preferred version of the present invention, the engagement
means 8a is provided on the side opposite the locking means 4, preferably in a position
diametrically opposed thereto.
[0060] According to a preferred embodiment of the present invention, the engagement means
8a, 8b each have a preferably sleeve-shaped configuration.
[0061] The engagement means 8a, 8b are provided arranged, during use, aligned with each
other along the pipe C, in particular along an axis parallel to the longitudinal symmetry
axis X of the pipe itself, in order to receive the adjustment means 8.
[0062] The adjustment means 8 for the tuning device 1 according to the present invention
comprise an adjustment bar 10. The adjustment bar 10 is engaged with the respective
engagement means 8a, 8b along an axis parallel to the longitudinal axis X of the pipe.
The engagement means 8b, in a version of the embodiment in which they have a sleeve-shaped
configuration, as illustrated in a non-assembled form in figure 4, comprise an internal
sleeve 8b1 and an external sleeve 8b2.
[0063] In one version of the invention, the adjustment bar 10 comprises a portion 10a with
substantially circular and threaded cross section, passing through the sleeve-shaped
engagement means 8b, or through the internal sleeve 8b1, provided on the tubular portion
7.
[0064] The internal sleeve 8b1 or generally the sleeve-shaped engagement means 8b, as will
be described hereinbelow, has an internal thread with pitch corresponding to the thread
pitch of the adjustment means 8, in particular of the threaded portion 10a of the
bar 10. The external sleeve 8b2 is instead internally smooth and adapted to be coupled
with the internal sleeve 8b1.
[0065] The engagement means 8a, in a version of the embodiment in which they have a sleeve-shaped
configuration, as illustrated in figure 3, comprise an external sleeve 8a2. The cylindrical
opening of the external sleeve 8a2 is not threaded, but rather is smooth.
[0066] The adjustment bar 10 also has an end portion 10b, preferably with cylindrical form,
rotatably mounted in the engagement means 8a or in the external sleeve 8a2 provided
on the support collar 2.
[0067] At the opposite ends of the end portion 10b, fixed locking portions can be provided,
in a manner so as to prevent the end portion 10b from sliding along the adjustment
bar 10. The adjustment bar 10 also comprise a grip portion 11, e.g. obtained by means
of a sleeve 11a fixed in any suitable manner to the bar itself.
[0068] In one version of the invention, the bar 10 is a worm screw.
[0069] In one version of the invention, the bar 10 has, during use, the grip portion 11
at the top of the pipe C or tubular portion 7, such that it is easy for an operator
to grip the bar above of the pipes C of the instrument.
[0070] With one such configuration, it is clear that it is possible to manually operate
on the bar 10, possibly by means of use of a suitable tool, for example a screwdriver
or a suitable coupling bar, in a manner such that the heat of the hand does not affect
the metal forming the pipe and hence the tuning does not result altered.
[0071] The actuation of the bar 10 occurs by rotating it around its longitudinal axis and
thus obtaining a translation of the tubular portion 7 to or from the free end of the
resonator, depending on the rotation direction imparted to the bar.
[0072] In an alternative version of the invention, the bar 10 has, during use, the grip
portion 11 at the end of the pipe C opposite its top, or at the support collar 2.
[0073] In such case, for example for long pipes, the tuning procedure can occur from the
bottom, without risks for the operator.
[0074] In such a manner, in fact, it is easy for an operator to grip the bar below the pipes
C of the instrument, by rotating the bar 10 from the bottom, e.g. remaining on the
ground and being able to tune pipes C even of considerable height.
[0075] The external sleeves 8a2 and 8b2 have, at the cylindrical side wall thereof, a flat
or flattered portion 8a3 and 8b3.
[0076] The function of the flat portion 8a3 and 8b3 will be explained in detail in the course
of the present description.
[0077] In a preferred embodiment, the flat portion 8a3 and 8b3 is positioned on the opposite
side with respect to the zone of the cylindrical side portion of the respective sleeves
which will be fixed, e.g. by means of welding, respectively to the support collar
2 and to the tubular portion 7.
[0078] The external sleeves 8a2 and 8b2 and the flat portions 8a3 and 8b3 have a threaded
through opening which is in communication with the hollow internal portion of the
respective sleeves.
[0079] Such threaded through opening is substantially orthogonal to the longitudinal axis
X of the pipe C.
[0080] The tuning device according to the present invention can also comprise means 12 for
locking the bar 10 in position, in a manner such that, once the position of the tubular
portion 7 has been adjusted with respect to the support collar 2, such position cannot
be changed over time, e.g. due to the vibrations of the pipe C when in use.
[0081] Such position locking means 12 comprise means for tightening the bar at the respective
engagement means 8a, 8b, e.g. a pair of screws 12a, 12b each provided for being screwed
in the corresponding threaded opening, if necessary obtained in the respective engagement
means, i.e. in the corresponding opening present in the external sleeves 8a2 and 8b2
and in the flat portions 8a3 and 8b3.
[0082] In one version of the invention, such screws 12a, 12b are positioned in a manner
such to respectively abut against the portion 10b of the bar itself and/or against
the internal sleeve 8b1, preventing the further rotation of the bar 10.
[0083] Due to the position locking means 12, the engagement means 8a and 8b act as if they
were made of a single piece, i.e. that the external sleeve 8b2 is integral with the
internal sleeve 8b1, with the flattened portion 8b3 and with the tubular portion 7.
[0084] Analogously, the external sleeve 8a2 is integral with the flat portion 8a3 and with
the support collar 2.
[0085] In one version of the invention, the external sleeve 8b2 is obtained in a single
piece with the flattened portion 8b3 and/or the external sleeve 8a2 is obtained in
a single piece with the flat portion 8a3.
[0086] The diameter of the bar 10 and the width of the thread can depend on the size of
the pipe C to be tuned. Therefore, such size can be varied according to the specific
needs of the tuner.
[0087] When the support collar 2 and the tubular portion 7 are applied on the resonator
of the pipe C, they can be found at a certain distance from each other or in abutment
against each other. In the latter case, the edge 2a of the support collar 2, directed
towards the tubular portion 7, and the edge 7a of the tubular portion 7, directed
towards the support collar 2, are in contact with each other. With the adjustment
by the adjustment means 8, the edge 7b of the tubular portion 7 may be projecting
with respect to the free and/or upper and/or terminal end of the resonator, and acts
as top edge of the resonator or of the pipe C itself.
[0088] Therefore, considering the positioning with respect to the free and/or upper and/or
terminal end of the pipe C, the tubular portion 7 is positioned at the same end while
the support collar 2 is positioned moved away from such end by a given section. Such
section corresponds at least to the height H of the tubular portion 7.
[0089] In one version of the invention, the edge 7b of the tubular portion 7 - in an initial
tuning step and after having fixed the support collar 2 and the tubular portion 7
on the pipe C - is placed precisely at the free and/or upper and/or terminal end of
the pipe itself. With the tuning, then, such edge will project with respect to such
end, as indicated above. The tubular portion 7, slidable with respect to the support
collar 2, can be spaced from the collar also by 2, 3 cm depending on the specific
needs, such that its edge 7b can during use be situated beyond the free and/or upper
and/or terminal end of the resonator, actually elongating the resonator by the amount
necessary and sufficient for emitting a sound at a desired frequency.
[0090] In such a manner, the tuning of the pipe occurs through the tuning device 1 according
to the present invention.
[0091] In addition, in such a manner, by calculating the size of the movement or elongation
of the edge 7b of the tubular portion 7 with respect to the free end of the pipe C,
it is possible to know the exact length variation (and hence emitted sound variation)
of the antique pipe with respect to the original, therefore also acting as a research
means for conducting a study of antique organs, in particular of their pipes and of
the variation that the same have sustained over time.
[0092] In a further version of the invention, the support collar 2 and/or the tubular portion
7 can have, at the inner surface thereof in contact with the pipe C or resonator,
a layer of felt or leather or suede or other low friction material, possibly soft,
capable of preventing the surface damaging or rubbing of the pipe following the application
of the support collar 2 and/or sliding of the tubular portion 7 thereon, without simultaneously
preventing the sliding of the tubular portion 7.
[0093] According to a method for tuning a pipe musical instrument, such as an organ or a
musical wind instrument, the present invention provides for applying a support collar
2 on the resonator or on each pipe C at a preset distance from the free end of the
resonator itself.
[0094] More particularly, this step involves tightening the support collar 2, e.g. by fixing
the locking means 4 around the two ears or slots 6 present in the same, in a manner
such that the collar is stably anchored in the pipe itself.
[0095] It is then provided to apply the tubular portion 7 at the free and/or upper and/or
terminal end of the resonator of the pipe C and to engage the support collar 2 and
the tubular portion 7 together by means of the means 8 for adjusting the mutual distance
between the tubular portion 7 and the support collar 2, possibly - depending on the
configuration - by means of the use of engagement means 8a, 8b.
[0096] It is then provided to adjust the mutual distance between the tubular portion 7 and
the support collar 2 as a function of the desired frequency to be emitted by the pipe
C in question during use.
[0097] The distance adjustment step, as already mentioned above, consists of longitudinally
sliding the tubular portion 7 with respect to the support collar 2, and consequently,
of varying the overall height of the resonator of the pipe C, thus adjusting the frequency
thereof.
[0098] According to the present invention, therefore, one operates on the overall height
of the entire pipe, without having to make slits or windows in the pipe itself, preserving
the complete integrity thereof.
[0099] The longitudinal sliding or translation of the tubular portion 7 with respect to
the support collar 2 occurs by means of the actuation of the adjustment bar 10, for
example by means of screwing the threaded bar in one sense or in the other depending
on the case.
[0100] In this manner, the tuning occurs, from the top or bottom, without having to touch
the pipe C. In such a manner, therefore, there is no risk that the heat of the operator's
hand can make the metal of the pipe expand, thus altering the correct measurement
of the desired frequency.
[0101] In one version of the invention, the support collar 2 and/or the tubular portion
7 are made of brass.
[0102] In an alternative version, the support collar 2 and/or the tubular portion 7 can
be made of plastic material; in such version, the plastic material has good wear resistance,
good "anti-adherence" and/or good chemical inertia.
[0103] For example, the support collar 2 and/or the tubular portion 7 can be made of polytetrafluoroethylene
(or PTFE), i.e. a tetrafluoroethene polymer, normally known through its commercial
names such as Teflon, Fluon, Algoflon or Hostaflon, in which other stabilizing and
fluidifying components are added to the polymer in order to improve the application
possibilities thereof.
[0104] PTFE is a material having a very low friction coefficient, and therefore it allows
a facilitated sliding of the support collar 2, during its positioning, and/or of the
tubular portion 7, during the tuning.
[0105] In a still further version of the invention, the support collar 2 and/or the tubular
portion 7 can be made of synthetic polyamide or nylon, the latter being the name of
a particular family of synthetic polyamides, i.e. aliphatic polyamides.
[0106] Such materials, given that they are resistant to high temperatures, are not affected
by the temperature variations to which such musical instruments or the various components
thereof are subjected.
[0107] In addition, such materials, especially Teflon or polytetrafluoroethylene, being
chemically inert, are resistant to salt or other substances with which they can come
into contact.
[0108] It is clear that also the further components of the tuning device according to the
present invention, including the adjustment bar 10 and the grip portion 11, can be
made of such plastic materials.
[0109] In addition, even the various sleeve-shaped or nut-shaped components present in the
device according to the present invention can be made of such plastic materials, and
in particular of Teflon, since the possible thread obtained therein is maintained
over time due to such materials.
[0110] Finally, such materials, having a kind of "self-lubrication", slide and are screwed
on each other without difficulty and seizure, which could comprise the functionality
thereof.
[0111] An expedient for the good operation of the tuning device 1 is that, as stated above,
the adjustment means 8 and the engagement means 8a, 8b are mounted perfectly aligned
with each other along an axis parallel to the longitudinal axis X of the pipe C.
[0112] For such purpose, the tuning device according to the present invention comprises
auxiliary alignment means (illustrated in figure 2) between the above-described sleeves
8a and 8b, in a manner such that the bar 10 passing therein can easily turn in the
same and consequently easy sliding/translation of the tubular portion 7 can be allowed
with respect to the support collar 2 and the resonator.
[0113] Such auxiliary means comprise a device for aligning the resonator or the pipe C,
adapted to receive the pipe C provided with a support collar 2 and with a tubular
portion 7, or in particular the upper or terminal part of the pipe C provided with
such components. Such alignment device allows aligning the longitudinal axis of the
pipe C along a predetermined direction.
[0114] The alignment of the pipe can occur by centering the same with respect to the aforesaid
auxiliary means.
[0115] Such predetermined direction corresponds to the longitudinal extension of an alignment
bar 100, having a longitudinal symmetry axis, as described hereinbelow.
[0116] The alignment bar 100 is adapted to allow the alignment of the engagement means 8a
and 8b along an axis parallel to the longitudinal axis of the pipe C. In such a manner,
the engagement means 8a and 8b, as indicated above, will be aligned with each other
and with the longitudinal axis of symmetry of the pipe C and of the alignment bar
100. This alignment allows the adjustment means 8 to easily slide within the engagement
means 8a and 8b and, at the same time, to translate the tubular portion 7 of the tuning
device 1 along the resonator to be tuned or along its longitudinal axis X.
[0117] The alignment bar 100 has a square section or at least one flat face and through
holes 101, perpendicular to the longitudinal symmetry axis of the alignment bar 100
and to the at least one flat face thereof, for the alignment of the engagement means
8a and 8b. The through holes 101 are aligned along the longitudinal symmetry axis
of the alignment bar 100.
[0118] The alignment bar 100 is fixed to means for adjusting its height and its angular
tilt with respect to the longitudinal symmetry axis X of the pipe C.
[0119] In one embodiment, such adjustment means comprise a hinge support 102, to which the
alignment bar 100 is fixed, which allows varying the angle between the pipe C and
the alignment bar 100, in order to arrange the latter, with regard to its longitudinal
extension, in a manner parallel to the longitudinal axis of the pipe itself.
[0120] The hinge support 102 is in turn fixed to a support plate 103, height-adjustable,
in order to vary the height of the alignment bar 100 with respect to the pipe C.
[0121] Also fixed to the alignment bar 100, through suitable screws 105, are fixing means
or bolts 104 insertable in the through holes 101 present in the bar itself.
[0122] In particular, the screws 105 have a length such to allow the fixing of the fixing
means or bolts 104, of the alignment bar 100 and of the engagement means 8a and 8b.
In particular, the screws 105 are screwable in the openings present in the latter,
ensuring that the flat portion 8a3 and 8b3 comes into contact with one face of the
alignment bar 100, which as said has a square section or at least one flat face. In
such a manner, the engagement means 8a and 8b are aligned along the longitudinal symmetry
axis of the alignment bar 100 which, as stated, is parallel to the axis of symmetry
of the pipe C. Therefore, the engagement means 8a and 8b can be respectively welded
to the support collar 2 and to the tubular portion 7, with the certainty that the
same have the correct alignment along the pipe C in order to allow the sliding of
the adjustment means 8 at their interior and hence the movement of the tubular portion
7 with respect to the support collar 2, in order to determine the tuning of the pipe
C.
[0123] In one version of the invention, the engagement means 8a and 8b can of the type or
of material suitable for the same to be able to respectively lock the internal sleeve
8b1 and the external sleeve 8b2, or in a further version the end portion 10b and the
external sleeve 8a2, respectively turning or rotating the internal sleeve 8b1 on the
external sleeve 8b2 or the external sleeve 8a2 on the end portion 10b. In one version
of the invention, the internal sleeve 8b1 and/or the end portion 10b can each be made
of two components, which can be of the type or of material suitable for the same to
be able to be respectively locked on the adjustment bar 10, respectively tuning or
rotating the two components of each element, such as a nut and lock nut.
[0124] The tuning device according to the present invention respects the new international
standards with regard to restoration since it is reversible, in the sense that, especially
for the most antique instruments that are subjected to protection, the tuning device
can be easily removed without at all damaging or altering the pipe on which it was
fixed.
[0125] In modern instruments, however, the support collar of the tuning device according
to the present invention can if desired be stably fixed, for example welded, to the
respective pipe.
[0126] In addition, with a tuning device according to the present invention, it is possible
to vary the emission frequency of each pipe with deviation on the order of tenths
of frequency or tenths of hertz, i.e. during tuning it is possible to modify the sound
that can be emitted with a given pipe, even by a tone.
[0127] In addition, the tuning thus remains stable over time, without destructive operations
on the pipes themselves.
[0128] Thus, the invention attains the proposed objects.
[0129] The present invention was described according to preferred embodiments, but equivalent
variants can be conceived without departing from the protective scope offered by the
following claims. In addition, the characteristics described for one version or embodiment
can also be present in other variants or embodiments, without departing from the protective
scope offered by the following claims.
[0130] Hence, for example, the means for adjusting the distance between the movable tubular
portion 7 and the fixed support collar 2 can be obtained by equivalent means, so long
as they precisely achieve the longitudinal movement of the tubular portion 7 with
respect to the support collar 2 and hence with respect to the free and/or upper and/or
terminal end of the resonator of the respective pipe C. In place of the adjustment
bar 10, which can be threaded, for example, a cylindrical non-threaded bar could be
provided and the movement of the tubular portion 7 with respect to the fixed support
collar 2 could occur by means of a manual translation by an operator.
[0131] Additionally, in place of the adjustment bar 10, which can be threaded, a longitudinal
rack could be provided for connecting between the support collar 2 and the tubular
portion 7 and the latter could be fixed in a known manner to a toothed wheel provided
slidable on the rack and hence with respect to the support collar 2.
[0132] In addition the movement or adjustment might not be manual but mechanical, electrical,
electronic or mechanized, e.g. by means of actuation means.
[0133] The actuation means can for example comprise a drive motor or a gear motor group.
[0134] In such case, the drive motor or gear motor group can be positioned at the grip portion
11 or at one end of the adjustment bar 10 or at the end portion 10b of the adjustment
bar 10, or they can be connected thereto.
[0135] The actuation means can further comprise means for transmitting motion, interposed
between the drive motor or gear motor and the grip portion 11 or the end of the adjustment
bar 10. In one version of the invention, the motion transmission means comprise at
least one flexible element, capable of transmitting the motion generated by the drive
motor or gear motor and connecting the adjustment rod 8, without gears. Such motion
transmission means, being flexible, allow the actuation of the adjustment bar 10 in
a facilitated manner, without requiring the flexible element to be perfectly aligned
with the adjustment bar itself.
[0136] Such expedients can be particularly useful if long (e.g. from 4 m to 8 m) or heavy
pipes are present.
