Definitions

  • the present invention refers to.a device for stringing of strings in pianos, grand pianos, harpsichords, zithers and the like where a two-armed rocker is journalled in a frame and where one end of the rocker is attached to the string and the other end is affected by a tuning screw or the like.
  • Devices hitherto used for stringing of pianos, grand pianos, and similar stringed instruments usually consist of a so-called tuning pin or a similar screw formed means around which the string is wound.
  • the tuning pin is threaded in a so-called tuning block or the like whereby the friction of the thread must be high enough to resist the tractive force of the string.
  • This force is very high in pianos and grand pianos and therefore high manual force is required to prolong or shorten the string at tuning. This gives rise to difficulties to adjust rather small deviations in pitch, as the tuning screy has a tendency to move by leaps at the stringing.
  • tuning rockers which are two-armed rockers journalled in the frame of the instrument, one arm of the rocker being attached to the string and the ether end being affected by a tuning screw or the like.
  • U.S. patent 613900 One example of such a construction is shown in the U.S. patent 613900 and a further improved tuning rocker is shown in the Swedish patent 7304806-8.
  • both these constructions require that the rough tuning and the precision tuning take place at the same working moment, which puts great demands on the piano tuner, among other things a relatively exact estimate of the length of the string must be made from the beginning.
  • An object of the present invention is therefore to provide a device for stringing in which rough tuning takes place in a simple way reminding of the conventional tuning pin principle, but which also offers a possibility of precision tuning whereby the rough tuning as well as the precision tuning imply an absolute fixing of the string stretch which gives a stable pitch of sound.
  • FIG. 1 denotes a tuning rocker journalled in a groove 6 in a part 5 of a frame in a piano or the like.
  • a string 9 is attached and the other end of the rocker is coupled to another part 4 of the frame of the instrument by means of a screw 3 and a casing 2 in which the rocker 1 can be turned.
  • the rocker has two thin sections 7 and 8, the section 7 being intended to rest in the groove 6 at rough tuning as shown in Fig. 1 while the section 8 is the section around which the string 9 is wound at rough tuning.
  • the rocker according to the drawing has a six-sided cross-section as is apparent from Figure 3 and when the rocker is moved to the left in the figure so that this part will rest in the groove 6, the rocker is lockedas regards the turning around its own longitudinal axis. This takes place after the rough tuning has been made by turning of the rocker either manually or by means of some suitable tool. When the rocker thereafter is brought to take the position shown in Fig. 2 a precision tuning of the string stretch takes place by means of turning the screw 3.
