Abstract

Abstract In a bridge for stringed instruments of the type including a base member, a plurality of drums, and means connecting the drums to the base member in end-to-end relationship for independent lateral movement in two orthogonal directions to separately adjust the length and height of each string, there is disclosed an improved construction wherein the strings are conducted into engagement with the drums so as to apply an axial force to each of the drums to urge all of the drums axially into contact with each other and the first drum into contact with a fixed abutment on the base member.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 237 words
A bridge for a stringed instrument including a body and a neck comprising: a base member rigidly connectable to said body of said instrument, said base member having a first section connectable to said body of said instrument and a second section connected to one end of said first section and extending perpendicular thereto; a plurality of drums, each of said drums having an internally threaded hole extending laterally therethrough; a plurality of bolts extending through said second section of said base member and through said holes in said drums for connecting said drums to said base member in end-to-end relationship for independent lateral movement in two orthogonal directions whereby rotation of said bolts relative to said drums moves said drums towards or away from said second section of said base member; a fixed abutment associated with said base member, adjacent one end of the first one of said drums; and a plurality of holes in said second section of said base member, one for each of said drums, said holes being positioned intermediate said bolts, said strings extending through said holes in said base member and over said drums at an acute angle relative to said bolts without engagement with said bolts so as to apply an axial force to each of said drums and to urge all of said drums axially into contact with each other and said first drum into contact with said abutment.
Claim 2
Dependent Claim 237 words
A bridge for a stringed instrument including a body and a neck comprising: a base member rigidly connectable to said body of said instrument, said base member having a first section connectable to said body of said instrument and a second section connected to one end of said first section and extending perpendicular thereto; a plurality of drums, each of said drums having an internally threaded hole extending laterally therethrough; a plurality of bolts extending through said second section of said base member and through said holes in said drums for connecting said drums to said base member in end-to-end relationship for independent lateral movement in two orthogonal directions whereby rotation of said bolts relative to said drums moves said drums towards or away from said second section of said base member; a fixed abutment associated with said base member, adjacent one end of the first one of said drums; and a plurality of holes in said second section of said base member, one for each of said drums, said holes being positioned intermediate said bolts, said strings extending through said holes in said base member and over said drums at an acute angle relative to said bolts without engagement with said bolts so as to apply an axial force to each of said drums and to urge all of said drums axially into contact with each other and said first drum into contact with said abutment.
