Definitions

  • ABSTRACT A device which serves to secure strings in pianos and like stringed instruments in a simple and reliable manner with the aid of a swingably mounted tension element having an arcuate portion and a likewise arcuate groove therein, in which the string is placed in a state folded back upon itself so as to be clamped in the groove by wedge action when the element is swung and thereby tensioned.
  • This invention relates to a device for securing strings in pianos and like stringed instruments to an element that is arranged to be swung for tightening or tuning the string.
  • the device suggested according to the present invention has been constructed for the setting-up of strings in musical instruments but it also has other similar uses.
  • the novel features of the device according to the invention reside in that the device comprises an element which can be swung about an axis transverse to the direction of the string and in which a V-shaped groove is formed so as to extend in an are around said transverse axis, that a pin extending transversely of the direction of the string is provided at the distal end of said groove as viewed from the end of the string secured to an abutment, and that the distance between the boundary walls of the V-shaped groove at the bottom thereof is smaller than the cross section of the string, and a part of the string is bent about said pin and drawn along the bottom of the groove at some distance therefrom, while that part of the string which is fixed to the abutment shall extend, counted from the string part bent around the pin, along the groove exteriorly of said string part to urge it inwardly in the groove.
  • FIG. 1 is a side view of a tension lever with an element to which a string is to be secured
  • FIG. 2 is a view of said lever as seen from below;
  • FIG. 3 is a cross section of said lever
  • FIG. 4 is a view of said lever as seen from above;
  • FIG. 5 is a cross section of part of the lever shown in FIG. 2.
  • the tension lever is generally designated 1 and at one end has a recess 2 for a tension screw and at the other end an arcuate portion 5 which engages the string and coacts with a recess 4 formed in a support 3 and serving as a guide for the lever.
  • the tension lever 1 Upon tightening and untightening, respectively, of the screw which is shown by broken lines, the tension lever 1 will thus swing about an axis passing through the center of the portion 5, the bottom of said portion sliding in the recess 4 which preferably also has an arcuate shape.
  • the lever has an edge-shaped projection 6 which when the lever is swung beyond a given angular position about the axis passing through the portion 5, engages the support 3, thereby forming a new axis for the lever to swing about.
  • the portion to which the string 9 is to be clamped has an arcuate surface 10 which is part of the arcuate portion coacting with the recess and to which the string 9 is a tangent.
  • a V-shaped groove 11 is formed in said arcuate surface 10 and at the distal part of the groove as viewed from the other end of the string the groove is of greater depth at 12.
  • a pin or like element 14 extends through the boundary walls 13 at the deeper part 12 of the groove.
  • the V-shaped groove 11 is of a width slightly smaller than the diameter of the string to be secured.
  • the end part 9 thereof is passed beneath the pin 14 so that said end part runs along the bottom of the groove past the recess 4 in the support 3 and through a recess 15 in the edge-shaped projection 6.
  • the remaining string is bent around the pin 14 and so oriented as to run exteriorly of the string end part 9' in the groove 11.
  • a device for securing strings in pianos and like stringed instruments to an element that is arranged to be swung for tightening or tuning the string wherein the device comprises an element which can be swung about an axis transverse to the direction of the string and in which a V-shaped groove is formed so as to extend in an are around said transverse axis, a pin extending transversely of the direction of the string is provided at the distal end of said groove as viewed from the end of the string secured to an abutment, and the distance between the boundary walls of the V-shaped groove at the bottom thereof is smaller than the cross section of the string, and a part of the string is bent about said pin and drawn along the bottom of the groove at some distance therefrom, while that part of the string which is fixed to the abutment shall extend, counted from the string part bent around the pin, along the groove exteriorly of said string part to urge it inwardly in the groove.
  • V-shaped groove runs in an arc concentrically around the axis which the element can be caused to swing about.
  • V-shaped groove extends along a portion of the element that has an arcuate surface which is adapted to engage with and be received in an arcuate recess in a support, so that upon swinging of the element the arcuate surface will slide in said recess.
