| Abstract: |
A bridge assembly for a stringed musical instrument having a block-like platform member secured to a bridge member which is fixed with respect to a sound board cover of the instrument the bridge member has an upper surface with a groove therein seating of the platform member. The platform member has a lower portion fixedly inserted in the groove and an integral upper portion extending out of the groove and above said upper surface of the bridge member. A string of the instrument passes on a saddle under tension, the contact of the string with the saddle establishing the vibration length of the string. The saddle is connected to the platform member for longitudinal adjustment thereon to effect string length fine tuning. The saddle is movable between end positions at which the saddle remains positioned above the lower portion of the platform member so that vertical force applied to the saddle by the string will always be transmitted to the lower portion of the platform member therebelow and then to the bridge member and the sound board cover.

What is claimed is:
1. A bridge assembly for a stringed musical instrument having adjustment for string length fine tuning, the musical instrument having a resonating box with a sound board cover on which the bridge assembly is mounted, said bridge assembly comprising a bridge member fixed with respect to the sound board cover of the musical instrument, a block-like platform member secured to said bridge member, said bridge member having an upper surface with a groove therein for said platform member, said platform member including a lower portion fixedly inserted in said groove, a saddle on which a string passes under tension, the contact of the string with the saddle applying vertical force to the saddle and establishing a vibration length of the string, said block-like platform member projecting from said groove to provide an upper support surface for said saddle which has no underlying contact with said upper surface of said bridge member so that the force applied to the saddle will be substantially entirely transmitted through the lower portion of the platform member to the sound board cover via said groove in the bridge member without being transmitted to the upper surface of the bridge member and means connecting the saddle to the platform member, for adjustment of the saddle, longitudinally of the string, on the platform member to vary the vibration length of the string and thereby effect string length fine tuning and for longitudinally adjusted positions of the saddle between end positions the saddle transmits the vertical force applied thereto by the string substantially entirely to said lower portion of the platform member therebelow and then to said sound board cover via the groove in the bridge member.
