摘要： This invention relates to an improved neck-body joint for a guitar-like musical instrument which joint minimizes the possibility of relative movement between the neck and body and permits the neck to be pitched at a desired angle relative to the body without weakening either element. The firm joint is achieved by (a) providing a tongue which extends from the end of the neck and a recess in the upper surface of the endblock, the recess being positioned and sized so as to permit the tongue to fit snugly therein and be secured therein when the neck and body are fully assembled; (b) providing a dove-tail projecton on the end of the neck which mates with a dove-tail channel formed at the mating end of the headblock and (c) reinforcing the body at a point substantially under the last fret of the fingerboard, such reinforcing being accomplished by securing first and second reinforcing bars respectively to the inside surfaces of the soundboard and the bottom board of the body at the point under the last fret with these bars extending from one sidewall of the body to the other, and attaching reinforcing bars to each of the sidewalls, the bars extending between and being connected to both the first and second reinforcing bars. The desired pitch angle for the neck is achieved by utilizing a soundboard having a large angle curve, the neck being pitched such that its upper surface is in a plane tangent to the curvature of the soundboard at the back end thereof.

摘要： A modified musical instrument string comprising a core having a fine cover wire helically wound thereon, said cover wire having a substantially round cross-section over the major proportion of its surface, but having compressed flats at the crown of said wire at the outer surface of said string but not at the inner surface of said cover wire. Said modification is effected by apparatus comprising a first roller having a fixed axis and a second roller mounted on a moveable arm for moving the second roller toward and away from the first roller, and a controllable air cylinder apparatus connected to said moveable arm for moving the second roller toward the first roller. As the string being wound and rotating passes between the two rollers between guides, the crown or outer arcuate surface of the helical winding at the outer surface of the string is flattened by passing the string while it is rotating between rollers biased toward each other, resulting in a string which produces less noise when the player slides his fingers along the string to change positions, and which still provides perfect intonation and frequency response. The method for modifying such a wound musical instrument string is also disclosed.

摘要： Apparatus for modifying a musical instrument string as it is being fabricated by winding a fine metal wire helically about a core, the apparatus comprising a first roller having a fixed axis and a second roller mounted on a moveable arm for moving the second roller toward and away from the first roller, and a controllable air cylinder apparatus connected to said moveable arm for moving the second roller toward the first roller. As the string being wound and rotating passes between the two rollers and is maintained between guides, the crown or outer arcuate surface of each helical winding is flattened at the outer surface of the string, resulting in a string which produces less noise when the player slides his fingers along the string to change positions, and which still provides perfect intonation and frequency response.
