Abstract
Abstract Devices for supporting guitar strings at the bridge and nut ends of the keyboard include a body portion with an axially vertical threaded bore that houses a screw element. A slot is provided in the body so that the string rests and is supported on the upper surface of the element. The element has a surface recess adapted for reception of a tool used to raise and lower the element in the bore and to thus raise and lower the support for the string. The recess is preferably surrounded by a flat uninterrupted surface to provide a string supporting surface at all rotative positions. If movement of the support longitudinally of the string is desired, a screw member mounted on a bracket and engaging the body portion within a threaded bore below the screw element may be used.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
175 words
A guitar comprising an elongated horizontally arranged keyboard, a guitar string suspended over the keyboard, and a device mounted at one end of the keyboard for thereat supporting said guitar string above the keyboard, said device comprising a body portion having vertically spaced apart upper and lower faces, horizontally spaced apart opposite side walls located between said faces, an axially vertically arranged threaded bore located between said side walls and opening upwardly through the upper face of the body portion, and a vertical slot which lies in a plane common to the axis of said bore and which opens laterally of the body portion through said side walls and upwardly through said upper face, and a threaded screw element which threadedly engages the body portion within said bore and has an upper surface that is located below said upper face; said guitar string being received in said slot and supported on said upper surface, and said screw element being axially adjustable in the bore by the rotatable manipulation thereof with respect to the body portion.
Claim 2
Dependent Claim
175 words
A guitar comprising an elongated horizontally arranged keyboard, a guitar string suspended over the keyboard, and a device mounted at one end of the keyboard for thereat supporting said guitar string above the keyboard, said device comprising a body portion having vertically spaced apart upper and lower faces, horizontally spaced apart opposite side walls located between said faces, an axially vertically arranged threaded bore located between said side walls and opening upwardly through the upper face of the body portion, and a vertical slot which lies in a plane common to the axis of said bore and which opens laterally of the body portion through said side walls and upwardly through said upper face, and a threaded screw element which threadedly engages the body portion within said bore and has an upper surface that is located below said upper face; said guitar string being received in said slot and supported on said upper surface, and said screw element being axially adjustable in the bore by the rotatable manipulation thereof with respect to the body portion.
