Description

Pegs for stringed instruments. The size and texture (the Frictional area and: is the frictional pressure between the vertebra and its lining of great importance for the usability of the vortex. One has in general hitherto the force which was used when the strings were tightened. whose tension arises, used to locate the vertebra only in rare cases. This power can be used to make and also by mechanical change of the frictional pressure the vortex To give the appropriate course lies in the following constructions, as they are the subject the invention are based on the idea.

The string tension is first made usable by the fact that the peg by the circumstance! -that the lining on the opposing friction surfaces is shifted laterally, is wedged in place. Determined from the outset about the vortex To assign contact points, the vertebra receives either a guide ring or a guide disc (abbot, i), or he receives passages, notches in which -that Lining engages (Fig. I a).

The same end is pursued in a more perfect way if one uses the The guide ring or the guide washer is inserted into the jaw chuck (Fig. 2). Guide ring In this case, logs or logs are forced against the inner walls of the cavity. The vortex itself runs in hollowed-out niches. Corridors (section 2a).

Instead of a projection of the vertebra into the jaw chuck can of course The jaw chuck engages in the notches of the vertebra just as well (Fig.4).

You can now by the fact that you aas jaw chuck in width, length or height direction - and through easily adjustable devices, Holding screw connections, etc. together, the pressure of the lining on the vertebrae itself, on its guide rings and logs or on the notches as desired rules (Dept. -2a, 3a, 4a, 5a).

One can also insert the vertebra between the two chucks into a hollowed one Shift gear and -the adjustability of the jaw chucks to each other to regulate the. Use friction pressure alone (Fig.5). In that case, however, the effect will be : the string pull pretty much lost. The vertebra, which before being screwed together the two Baoken chucks are put in, alternatively receives two guide rings.

Finally, the frictional pressure can still be regulated by cuts through the length of the shaft of the vertebra and the parts thus obtained holds together by screw connections or other easily adjustable devices. The adjustment; the ability of parts to increase or decrease in relation to one another the frictional pressure (Fig.6).

In all illustrations f the jaw chuck, r the guide ring, e the notches, s the guide disc, ia niche, hollowed-out passage of the vertebra, v screw connections.

Claims (3)

PATENT CLAIMS r. Pegs for stringed instruments, characterized in that that the vortex bearing from two opposing, offset arranged Friction surfaces exist so that the vortex is determined by the zag of the tense strings will. 2. vertebra according to claim i, characterized in that the vertebra with a with it intimately connected guide ring or logs embedded in the jaw chuck is. 3. vertebra according to claim i, characterized in that the vertebra notches has, in which the bearing engages. Vortex according to claim i, characterized in that that the camp cut through in length, width or height direction and adjustable Devices, e.g. B. fittings, is held together so that the frictional pressure of the bearing on the vertebra itself, its guide rings or = logs, or on its Notches can be changed at will. 5. vertebra according to claim i, da., Harsh characterized in that the shaft of the vertebra cut through in the longitudinal direction and by controllable devices, e.g. B. fittings, is held together so that the frictional pressure of the vortex on its bearing can be varied at will.
