Description
Zweck dieser Stimmgabel ist:The purpose of this tuning fork is:
1. Jedermann zu befähigen, seine Musikinstrumente mit größter Genauigkeit selbst zu stimmen;1. To enable everyone to tune their own musical instruments with the greatest possible precision;
2. dem Physiker ein Mittel zu bieten, Tonhöhen mit mathematischer Genauigkeit zu bestimmen.2. To provide the physicist with a means of determining pitches with mathematical accuracy.
Auf beide Zinken a der Stimmgabel sind Gewinde geschnitten, auf welchen je eine Mutter b als tonänderndes Gewicht verschraubbar ist. Diese ist aufgeschnitten und kann durch zwei Klemmschrauben c an das Gewinde gepresst werden. Die äußeren Seiten der Zinken sind glatt gefeilt, um an diesen Flächen d entweder die Töne (für den Gebrauch in der Musik) oder die Schwingungszahlen (für den Gebrauch in physikalischen Laboratorien) anzuschreiben, welche den bezüglichen Stellungen der Muttern entsprechen.Threads are cut on both prongs a of the tuning fork, onto each of which a nut b can be screwed as a tone changing weight. This is cut open and can be pressed onto the thread using two clamping screws c. The outer sides of the prongs are smoothly filed in order to write on these surfaces d either the tones (for use in music) or the vibrations (for use in physical laboratories) which correspond to the relative positions of the nuts.
