Abstract: A device for changing the timbre of a stringed instrument of the violin or viol family. The device includes a plurality of sympathetic strings, rigidly fixed at opposite ends in a frame suspended over a sound board of the instrument. A javari bridge is mounted on the sound board, a distance from a main bridge, with the sympathetic strings passing over the javari bridge. When the sympathetic strings are set into vibration by the main strings, the javari bridge brings out upper harmonic vibrations in the sympathetic strings, changing the timbre of the instrument. The javari bridge also makes the upper harmonic vibrations more audible and shortens the period of vibration, avoiding the dissonance associated with sympathetic strings strung over a conventional bridge. When the javari bridge is stepped, the sympathetic strings may be strung in tiers, allowing more strings to be strung in less space and expanding the harmonic sounds produced by the instrument.

Abstract: A guitar bridge bias converter is described which provides the means of converting a right-handed steel strung electric or acoustic guitar to a left-handed instrument. The bridge bias converter for an acoustic guitar consists most simply of an integral one-piece unit comprising a central plate, a lower tongue, and an upper bridge-bone. The tongue locates in the groove vacated by removal of the original right-handed bridge-bone. The plate sits on top of the bridge and the bridge-bone is situated on the plate at an angle which is diametrically opposed to the original bridge-bone. This has the effect, in conjunction with reversal of the string positions, of converting the guitar from right-handed to left-handed playing. An alternative embodiment appropriate to conversion of electric guitars is also described, comprising a replacement bridge block incorporating mounting hole protrusions so offset as to convert the instrument from right-hand to left-handed string bias.

Abstract: My device applies to acoustic guitars which have bridges glued to the guitar top. My device securely joins the bridge to the guitar top. Sometimes the tension of the strings pulling on the bridge separates it from the guitar top. My device attacks this problem by using a cross member support bar, which bears upon braces glued to the underside of the guitar top. Screws or other fasteners, threaded through the cross member support bar, guitar top, and bridge, joins them securely. The cross member support bar and fasteners may be installed during the original manufacturing process or added later after the musician has dislodged or separated the bridge partially or wholly from the guitar top. The effect of the cross member support bar, fastened to the bridge in the above manner, is to improve the sound of acoustic guitars.

Each bearing cylinder has a string throughbore extending perpendicularly to the cylinder axis and in alignment with a throughbore in the base body. An intonation tube, through which the corresponding string extends, is provided in each string throughbore, so as to be adjustable in axial direction of the intonation tube. An adjustment of the intonation tube in axial direction of the string throughbore results in an adjustment of the length of the string. A rotation of the bearing cylinder results in an adjustment of the height of the string.

Abstract: An adjustable bridge assembly for a stringed musical instrument utilizes individual adjustment blocks, one beneath each string, each fitted with a saddle screw having at its upper end a guidance groove supporting the corresponding string. The guidance groove may be shaped to accommodate different sized strings. The blocks, configured with elongated slots near each end engaged by screw fasteners, may be adjustably positioned prior to being fixed in place, thus enabling the bridge support point for each string to be set individually for good intonation and true octaves. The saddle screws, engaged in holes which are threaded into the block at an inclined angle so as to support each string at a well-defined point, allow each string's height above the fingerboard to be set independently for a desired tradeoff between ease of fingering and freedom from string-to-fingerboard buzz at maximum playing amplitude.

A track on the body of the instrument has a first depression for receiving the bridge of the instrument for that string. The bridge has a string raising saddle on it, which can be adjusted in height and can be adjusted parallel to the length of the string. The installed end of the string extends past the saddle to a slide supported in a second depression on the track. A bolt on the slide receives a nut supported at the track to adjust displacement of the slide between a position where the supported string is at highest pitch and a position to which the slide can shift for the string to be at lowest pitch. A pivotable eccentric lever has two cam surfaces on it at different distances from the pivot axis of the lever. The different high and low pitch levels of the string are established by the different pivot positions of the lever cooperating with the displacement slide. Displacement range is adjustable.

The rigid members are preferably mounted within a pliant soft plastic material such as Neoprene for supporting the rigid members in place and making the insert adaptable to different string heights. The rigid members, in their engagement between string and sound table, provide a second reverberation signal, a change in sustain, and a change in timbre, depending upon the particular material used.

Abstract: The invention relates to apparatuses, and methods for their use, for reversing or preventing warpage in the top plates of guitars and similar musical instruments attributable to the tensile forces within the strings of such instruments. The apparatus employs a compression block attached within the interior of an instrument's sound box, upon the interior side of the top plate and opposite the bridge, a compression rod between the compression block and the tail block of the instrument, and means within the interior of the sound box for adjusting the movement of the compression rod. When installed, the apparatus of the invention may be manipulated to induce a compressive force upon the interior side of the instrument's top plate, thus arresting or reversing the undesirable warpage in the top plate caused by the tension in the instrument's strings.

Abstract: A nut (30) and/or saddle (20) supports the strings (14) of a stringed musical instrument (10) allowing essentially fully unrestricted movement of the strings, both forward and background within the nut or saddle in order to maintain the proper pitch tuning of each string. Each string is retained at a fixed position at the nut or saddle, but allowed to move freely from these fixed positions when the strings are in motion such as when being tuned. A pair of freely-rotatably ball bearings (34a and 34b) are positioned in a countersunk pocket aperture 33 in the nut housing (32) and/or saddle housing (60) and in the case of the former, are positioned immediately juxtaposed to a pressure pad (41) for dampening each string from vibration between the nut assembly and the instrument tuner mechanism. A retainer (42) retains each pair of balls (34a and 34b) in the pocket aperture (33).

The saddle has a fulcrum end supported on the guitar from which an inclined lever portion extends at an acute angle with respect to the body of the guitar and has a free end on which the string passes and applies force to the saddle. The inclined lever portion defines a tapered space with the body of the guitar so that the applied double force of the string is transmitted via the inclined lever portion to its fulcrum end forwardly at the acute angle. For bass strings, the saddle can be formed with multiple angularly spaced legs and for treble strings with a solid, triangular cross section.

Abstract: An improved acoustic guitar bridge having string intonation, height, and tilt adjustment and comprising an anchor joined to and protruding downwardly from a chassis housing a plurality of forwardly and rearwardly adjustable saddles.

Abstract: A bearing of a roller string guide for a musical instrument, such as a roller bridge saddle, is urged into a seating by elastic member whose spring force preferably is greater than the lateral force exerted on the roller by the vibration of the string. The seating of the bearing is formed in a rigid structure of the bridge saddle. With this arrangement since the bearing is urged into a rigid seating the vibrational energy of the string cannot vibrate the roller laterally relative to the bridge saddle and therefore no vibrational energy of the string is lost in the connection between the roller and the saddle structure. With a bridge having a bearing saddle according to the invention string sustain is greatly enhanced.
