Abstract
Abstract A compact adjustable bridge and string-anchoring structure for stringed musical instruments in the form of a bar whose top surface carries in juxtaposition bridge sections, one for each string, which are mounted for movement in a direction longitudinally of the strings and are equipped with means operable to vary their positions individually. Arranged in the front edge area of the bar are open anchoring recesses provided with small funnel-shaped apertures in their rear walls for the strings to pass through and emerge at the rear edge area of the bar while the beaded ends of the strings are retained and sheltered in the recesses. This rear edge area is smoothly rounded for the strings to be folded upwardly over said area into engagement with the individual bridge sections on the top surface of the bar. The opposite ends of the bar are provided with hook-like extensions for attachment of the ends of the bar to the body of the instrument in a manner permitting individual adjustment of the bar ends in a direction longitudinally of the strings and also relative to the top surface of the instrument body.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
119 words
A combined bridge and string-anchoring device for stringed musical instruments comprising a bar having a top surface, a front edge area, a rear edge area and opposite end areas, a series of string-supporting bridge sections mounted in juxtaposition upon said top surface for movement in a direction longitudinally of the strings of the instrument to which the bar is attached, means operable from the front edge area of said bar for individually adjusting the position of said bridge sections, and means in said front edge area for retaining the beaded ends of the strings, while allowing the strings to pass to said rear edge area to be folded over said rear edge area and engaged over said bridge sections.
Claim 2
Dependent Claim
119 words
A combined bridge and string-anchoring device for stringed musical instruments comprising a bar having a top surface, a front edge area, a rear edge area and opposite end areas, a series of string-supporting bridge sections mounted in juxtaposition upon said top surface for movement in a direction longitudinally of the strings of the instrument to which the bar is attached, means operable from the front edge area of said bar for individually adjusting the position of said bridge sections, and means in said front edge area for retaining the beaded ends of the strings, while allowing the strings to pass to said rear edge area to be folded over said rear edge area and engaged over said bridge sections.
Claim 3
Dependent Claim
50 words
Device according to claim 1 wherein said front edge area has a series of tunnel-shaped recesses formed therein to receive and shelter the beaded ends of the strings, and funnel-shaped apertures formed in the end walls of said recesses for the strings to pass through to said rear edge area.
Claim 4
Dependent Claim
200 words
A combined bridge and string-anchoring device for stringed musical instruments in the form of a bar having a top surface, a front edge area, a rear edge area and opposite end areas, means at said end areas for detachably securing the opposite ends of the bar to the body of the instrument in a manner permitting individual adjustment of the location of said ends in a direction longitudinally of, and at right angles to the top surface of the instrument, a series of bridge sections mounted in juxtaposition upon said top surface for individual movement in a direction longitudinally of the instrument, means operable from said front edge area for individually adjusting the location of said bridge segments, and formed in said front edge area a series of juxtaposed, relatively spaced tunnel-shaped recesses having funnel-shaped apertures in their end walls for the strings to pass through to the bottom of said rear edge area while the beaded ends of the strings are retained and sheltered in said tunnel-shaped recesses, said rear edge area being of smoothly rounded contour for the strings emerging from said apertures to be folded upwardly along said rear edge area into engagement with said bridge sections.
Claim 5
Dependent Claim
