Ligature for a woodwind instrument mouthpiece

BACKGROUND

The present disclosure relates generally to improved ligatures for woodwind instruments.

Woodwind musical instruments generally include a reed securely coupled to a mouthpiece via a ligature. There remain areas in which ligatures can be improved. As dictated by the particular make and model of the instrument, a ligature must conform to mouthpieces having different angles. For example, as shown in FIG. 1A, a ligature, such as ligature 1004, can be sized to properly fit a mouthpiece with a regular or standard slope. Nevertheless, when the same ligature is applied to a mouthpiece having a steeper slope, as shown in FIG. 1B, a gap, such as gap 1026 between the cord 1006 and the mouthpiece, may occur, resulting in a loose fit.

The security of the engagement of the ligature and mouthpiece can also be improved. As shown best in FIGS. 2A-2B, the bridge 1016 includes an upper plate 1028, which surrounds the centrally located through hole 1022. A pair of legs 1030a, 1030b extend from the upper plate 1028, straddling the puller 1008, with the ends 1032a, 1032b of each the legs engaging the mouthpiece 1000. The arms 1030a, 1030b have a constant width, w, along a longitudinal direction 1034 of the mouthpiece from where the arm extends from the upper plate 1028 to the ends 1032a, 1032b. The contact area provided by the ends of the arm 1032a, 1032b undesirably allows the ligature 1004 to slip.

Also, ligature 1004 can scratch the instrument. Each of the arms also include planar faces, such as planar faces 1036a, 1036b of arm 1030a that face (i.e., run perpendicular to) the longitudinal direction of the mouthpiece. These planar faces include edges 1038a, 1038b that engage the surface of the mouthpiece, are capable of scratching the mouthpiece (FIG. 3B). Arm 1030b similarly yields sharp edges, such as edges 1038c, 1038d.

Referring now to the drawings, FIGS. 3A, 4A and 5A illustrate exemplary embodiments of a ligature of the subject disclosure, and particular components thereof. Ligature 104 includes a cord 106 that can be composed of, for example, a synthetic fiber such as Kevlar®; and a puller 108 extending in a longitudinal direction of the reed.

The puller 108 includes a plurality of through holes 110 extending through planar sides of the puller, the through holes are sized to receive the cord 106. A guide bar 118 extends proud of the puller, containing a threaded outer surface, sized and threaded to receive a fastener having complementary threads, which in this exemplary embodiment is in the form of a wingnut 120, though other fasteners such as a hex nut or the like could alternatively be employed. A bridge 116, which will be discussed in greater detail below, including a through hole 122 sized to be received by the guide bar 118 is also provided. The wingnut 120 includes a centrally located orifice 124 that is provided with threads complementary to the guide bar 118. The wingnut 120 engages the bridge 116 to secure the puller 108 to the mouthpiece.

The cord 106 winds around the reed in a spiral fashion, being introduced sequentially to another of the plurality of through holes 110 at each turn. The puller is preferably disposed at the twelve o'clock position with respect to the generally circular body of the mouthpiece, with the reed disposed at the six o'clock position. A pair of sound adjustment members 114a, 114b is provided, having a plurality of channels 116 sized to securely receive the cord 106 so as to locally prevent or attenuate vibration of the cords. The sound adjustment members 114a, 114b can be adjusted, for example, as disclosed in U.S. Pat. No. 9,183,817, hereby incorporated by reference in its entirety, to provide the desired vibration absorbing region to, in turn, provide a darker or brighter sound, as desired by the musician. Each sound adjustment member 114a, 114b may be composed of, for example, one piece or two or more pieces coupled together.

A distinction of ligature 104 is the bridge 116, which allows it to provide improvements over ligatures of the prior art. With reference to FIG. 5A, the bridge includes an upper plate 128, which surrounds the centrally located through hole 122. A pair of legs 130a, 130b extend from the upper plate 128, having a width, w, in the longitudinal direction 1034 of the mouthpiece when attached thereto. Unlike with bridge 1016, however, the legs 130a, 130b in this exemplary embodiment do not extend, at a constant width, to engage the mouthpiece. Instead, bridge 116 includes a mouthpiece skate 140, having an increased width, W, along the longitudinal direction 1034 of the mouthpiece.

In certain embodiments, the ratio W:w (i.e., the increased width of the mouthpiece skate along the longitudinal direction 1034 of the mouthpiece to the width of the arm) along the longitudinal direction 1034 of the mouthpiece can range from about 1.05 to about 8, about 1.2 to about 6, about 1.5 to about 5, or from about 1.7 to about 2.6 (e.g. about 2.3). For example, W can be, in certain exemplary embodiments, from about 4 mm to about 10 mm, about 6 mm to about 8 mm (e.g., 7 mm); and/or w can be from about 1.5 mm to about 5 mm, or from about 2 mm to about 4 mm (e.g., 3 mm).

With reference to FIG. 5D, the mouthpiece skate 140 includes a plurality of (e.g., three) segments. A first central segment 146 defines a plane 142 about its lowermost surface, generally parallel to a plane 144 defined by the top end of the upper plate 128. A first outer segment 148 extends from the first central segment upward at an angle, α, from the plane 142 defined by the first central segment 146. A second outer segment 150 extends from the first central segment upward at an angle, β, from the plane 142 defined by the first central segment 146. This configuration with a plurality of segments provides an angled pipe for tight contact with the mouthpiece. Overall, the skate is of a generally circular longitudinal cross section and curved, e.g., the skate extends in a generally upward direction.

Angles α and β can be the same or different. Further, in certain embodiments, the mouthpiece skate can extend at an angle at only one end. α and β can range from about 0.5 degrees to about 20 degrees, or from about 1 degree to about 15 degrees, or from about 5 degrees to about 10 degrees (e.g., about 7.5 degrees).

In another exemplary embodiment, shown in FIGS. 5B and 5E, a bridge 116′ is provided. Bridge 116′ is similar to bridge 116, and likewise includes a mouthpiece skate 140′, having an increased width, W, along the longitudinal direction 1034 of the mouthpiece, as compared to the width, w, of the legs 130a, 130b. In this exemplary embodiment, mouthpiece skate 140′ has a smooth tubular or rocker configuration, as opposed to being composed of a plurality of segments, which in turn provides smooth angle adjustment, as will be discussed in greater detail below. In certain embodiments the smooth tubular or rocker configuration is similar in shape to the shape of rockers on the bottom of a rocking chair. For example, the skate 140′ is of a generally circular longitudinal cross-section.

With reference to FIG. 5E, a lowermost surface of the midpoint of the mouthpiece skate 140′ defines a point tangent to a plane 152 generally parallel to a plane 144 defined by the top end of the upper plate 128. A first end 154 of the mouthpiece skate 140′ extends upward at an angle, γ, from the plane 152 defined by the midpoint of the mouthpiece skate 140′. A second end 156 extends upward at an angle, Δ, from the plane 152 defined by the midpoint of the mouthpiece skate 140′. Angles γ and Δ can be provided as α and β, described above.

In another exemplary embodiment, shown in FIGS. 5C and 5F, bridge 116″ is provided. Bridge 116″ provides arms and a skate 140″ of constant width, w. The mouthpiece skate 140″ is defined by a rounded pole, and has a first end 154″ that extends upward at an angle, ε, from a plane 152″ defined by a lowermost point of the midpoint of the mouthpiece skate 140″ and a second end 156″ that extends upward at an angle ζ, from a plane 152″ defined by the midpoint of the mouthpiece skate. Angles ε and ζ can be provided as α and β, described above, or alternatively one or more of the ends can extend at angles from about 1 or 5 degrees to about 50 or 75 degrees, such as from about 7.5 degrees to about 45 degrees. This particular embodiment provides the advantage of easier manufacturing.

In other exemplary embodiments, shown in FIGS. 6A-6C, the bridges includes an arm 130′ that extends at a non-perpendicular angle (i.e., at a slant or obliquely) from the plane 144 defined by the top end of the upper plate 128. Bridge 116″′, 116″″, and 116″″′ respectively include mouthpiece skates 140, 140′ and 140″, as with bridges 116, 116′ and 116″. These particular embodiments assist with an easy angle change. The tilted angle makes an inclining movement easier since the tightening force will move more efficiently with the vector angle than a straight vertical angle.

By virtue of the angled design of the mouthpiece skate, the presently disclosed ligatures can accommodate mouthpieces of different surface angles while maintaining a snug and secure connection with the mouthpiece. Upon tightening the wingnut, the bridge, and thus also the puller and ligature itself, changes angles depending on the mouthpiece surface angle of the mouthpiece to which the ligature is applied.

Another view of the ligature 104 with bridge 116′ positioned on a mouthpiece 1000, shown without the cord for purposes of clarity, is set forth in FIG. 9A. The bridge 116′ straddles the puller 108. The pair of sound adjustment members 114a, 114b is provided, having a plurality of channels 117 sized to securely receive the cord so as to locally prevent or attenuate vibration of the cords. As shown, in this exemplary embodiment, each sound adjustment member 114a, 114b is composed of two pieces coupled together. Disposed as in FIG. 9A in the three and nine o'clock positions, the sound adjustment members 114a, 114b can be adjusted as desired by the musician.

The bridge 116′ straddles the puller 108. As shown in FIG. 9B, the puller 108 in this exemplary embodiment has a first planar side 158 that includes eight equally spaced through holes 110 and a second planar side 150, opposite the first planar side, that includes six outer through holes and an elongated inner through hole 162. The cord (not shown) is intended to be threaded through the outer six through holes, with the bridge 116′ occupying the space of the inner two through holes along planar side 158 and the elongated through hole 162 of planar side 160. The guide bar 118 extends proud of the puller. The wingnut 120 includes a centrally located orifice 124 that is provided with threads complementary to the guide bar 118. The wingnut 120 engages the bridge 116 to secure the puller 108 to the mouthpiece.

The bridge 116′ is shown in FIGS. 9C-9D. The bridge 116′ includes an upper plate 128, which surrounds the centrally located through hole 122. A pair of legs 130a, 103b extend from the upper plate 128, having a width, w, in the longitudinal direction of the mouthpiece, and each terminating with a tubular skate 140′ having a width, W. Again, unlike with bride 1016, the legs 130a, 130b in this exemplary embodiment do not extend, at a constant width, to engage the mouthpiece. Instead, bridge 116 includes a mouthpiece skate 140, having an increased width, W, along the longitudinal direction 1034 of the mouthpiece. The dimensions W and w can be provided as set forth above.

A ligature 104′ according to another exemplary embodiment is shown in FIGS. 10-12. This ligature is similar to ligature 104, discussed above, but includes a puller 108′ and sound adjustment members 114a′ and 114b′.

The puller 108′ is shown in FIG. 11 and one or more of the through holes 110 is provided with an opening 163 along its upper end, as shown with through hole 162. Furthermore, the top surface of the puller 108′ can include top planar surfaces provided at an angle to guide the cord to the through hole, such as planar surfaces 164 and 166. This particular exemplary configuration allows for easier threading of the cord.

The modified sound adjustment member 114′ and 114″ is shown in FIG. 12. Sound adjustment members 114′ are similar to sound adjustment members 114, except that the channels 117 receiving cord 106 face outwardly instead of inwardly when assembled to the mouthpiece. While sound adjustment member 114′ contains 5 channels, other numbers of channels can instead be provided, such as, for example, sound adjustment member 114″, which contains six channels to receive the cord and attenuate vibration.

For example, as shown in FIG. 13A, a ligature 1004 of the prior art will not change its orientation when introduced, for example, to a mouthpiece with a steeper slope, as compared to a standard mouthpiece slope for which the ligature 1004 is designed to be applied. The puller 1008 is aligned parallel to the slope of the mouthpiece defined by its upper surface, and the guide bar 1018 is oriented perpendicular to the slope of the mouthpiece, and a gap 1026 results thereby forming a less than optimal fit.

In contrast, as shown in FIG. 13B, for a ligature of the present disclosure, upon being introduced to a mouthpiece with a significant slope, the bridge, by virtue of the ends of the of the mouthpiece skate being angled, will “rock” or pivot upon tightening the wingnut to automatically adjust the angle of the ligature to prevent gaps and provide a tighter and more confirming fit.

As shown in FIG. 14, the ligature and bridge 116 of the present disclosure, via the expanded contact surface area provided by mouthpiece skate 140 in certain embodiments, reduces the possibility of the ligature slipping. For example, as shown in FIG. 11, the bridge 116 is less likely to slip from the desired 12 o'clock position (or any desired initial position) to an undesired location (such as in the direction of 11 o'clock or 1 o'clock). Additionally, ligatures provided by the present exemplary embodiments of the present disclosure will also alleviate sharp edges that can scratch or cosmetically damage the instrument.

While the subject disclosure has been described with reference to exemplary embodiments, it will be appreciated by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the subject disclosure. In addition, modifications may be made to adapt a particular situation or material to the teachings of the subject disclosure without departing from the essential scope thereof. It is to be understood, therefore, that the subject disclosure is not limited to the particular aspects disclosed, but it is intended to cover modifications within the spirit and scope of the subject disclosure as defined by the appended claims and discussed above.
