Definitions

  • the present invention relates to a tuning device for pipe musical instruments, such as an organ or a wind musical instrument.
  • the currently used tuning modes are the following.
  • 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.
  • this is a mode for tuning of manual type, which requires highly specialized manual ability and very long execution times.
  • "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.
  • 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.
  • 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.
  • the pipe to be tuned must be made of a rigid material, capable of supporting the incision, and this is an irreversible procedure.
  • the pipe may result unstable after such tuning has been made.
  • the present invention resolves the above-lamented drawbacks.
  • the technical task of the present invention is therefore to improve the state of the prior art.
  • 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.
  • a further object of the present invention consists of obtaining a tuning device that allows an enduring and precise tuning.
  • a still further object of the present invention consists of obtaining a tuning device that allows varying the tuning and which is reversible.
  • 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.
  • 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.
  • 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.
  • 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.
  • the tuning device 1 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.
  • 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.
  • 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.
  • organs can be tuned by acting on the upper or terminal portion of the pipes.
  • 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.
  • 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.
  • 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.
  • the pipes are open at least at the top, possibly of labial type.
  • 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.
  • 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
  • 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
  • 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
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the tuning device 1 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.
  • 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.
  • 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.
  • Such side wall 3 or support collar 2 has a substantially C-shaped cross-section configuration.
  • 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.
  • the tuning device 1 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.
  • 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.
  • FIG. 3 One detail of the support collar 2, of the ears or slots 6 and of the locking means 4 is illustrated in figure 3 .
  • the support collar 2 can be easily mounted, either fixed or removable on the respective pipe C, as will be better described hereinbelow.
  • the tuning device 1 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
  • 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.
  • 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.
  • 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.
  • both the support collar 2 and the tubular portion 7 are positioned outside the pipe C.
  • 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.
  • 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.
  • 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.
  • 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.
  • the height h can have a size comprised between 0.5 cm and 2 cm.
  • the tuning device 1 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.
  • 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.
  • 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.
  • 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.
  • the engagement means 8a is provided on the side opposite the locking means 4, preferably in a position diametrically opposed thereto.
  • the engagement means 8a, 8b each have a preferably sleeve-shaped configuration.
  • 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.
  • the adjustment means 8 for the tuning device 1 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the bar 10 is a worm screw.
  • 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.
  • 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.
  • 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.
  • the tuning procedure can occur from the bottom, without risks for the operator.
  • the external sleeves 8a2 and 8b2 have, at the cylindrical side wall thereof, a flat or flattered portion 8a3 and 8b3.
  • 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.
  • 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.
  • Such threaded through opening is substantially orthogonal to the longitudinal axis X of the pipe C.
  • 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.
  • 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.
  • 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.
  • 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.
  • the external sleeve 8a2 is integral with the flat portion 8a3 and with the support collar 2.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the tuning of the pipe occurs through the tuning device 1 according to the present 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.
  • 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
  • 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.
  • the distance adjustment step 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.
  • 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.
  • 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.
  • the support collar 2 and/or the tubular portion 7 are made of brass.
  • 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.

  • PTFE polytetrafluoroethylene
  • 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.
  • 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.

  • 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.
  • 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.
  • the tuning device 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.
  • 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.
  • the alignment of the pipe can occur by centering the same with respect to the aforesaid auxiliary means.

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.
  • 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.
  • 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.
  • 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.
  • 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.
  • fixing means or bolts 104 insertable in the through holes 101 present in the bar itself
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • a tuning device 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.
  • the tuning thus remains stable over time, without destructive operations on the pipes themselves.
  • the invention attains the proposed objects.
  • 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.

  • movement or adjustment might not be manual but mechanical, electrical, electronic or mechanized, e.g. by means of actuation means.
  • the actuation means can for example comprise a drive motor or a gear motor group.
  • 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.
