Uebungsklavier.Practice piano.
Das auf beiliegender Zeichnung dargestellte Uebungsklavier hat ebenso wie die anderen Klaviere eine vollständige, fünf bis sieben Octaven umfassende Tastenreihe, welche in gewöhnlicher Weise gespielt wird.The exercise piano shown in the accompanying drawing has just like the others Piano a full row of keys consisting of five to seven octaves, which are in usually played.
Um einen leisen, aber sympathischen Ton zu erzielen, sind an Stelle der Saiten "Metallstimmen angeordnet, die durch einen an ihrem Ende vorübergleitenden Stift in Schwingung versetzt und zum Tönen gebracht werden.In order to achieve a quiet but pleasant tone, "metal parts" are used instead of the strings arranged, which are set in vibration and made to sound by a pen sliding past at their end.
Die zum Anreifsen der Stimmen dienende Mechanik ist wie folgt zusammengesetzt:The mechanics used to attack the voices are composed as follows:
Auf das hintere Ende der zweiarmigen Taste A wird die Brücke B aufgeschraubt, in welcher sich in C die einarmige Wippe D dreht. Diese wird durch die Feder E an die Puppe F gedrückt. An der Wippe D ist ein ■ Anreifszapfen G und ein mit Leder garnirter Zapfen H angebracht. . Die Tasten werden durch die Federn ρ ρ niedergehalten. Wird nun die Taste A angeschlagen, so steigt die "Wippe Z), wobei sie durch die Puppe F gleichzeitig nach hinten gedrückt wird, Fig. 2. Auf diesem Wege reifst nun der Zapfen G die Stimme K an, ähnlich wie die Stiftwalze einer Spieldose die Stimmen anreifst. In dem Augenblick, wo die Taste beim Niederdrücken auf die Basis L, Fig. 1, schlägt, also die Wippe sich in höchster Lage befindet, schiebt sich der Zapfen H unter den Hebel M, welch letzterer durch den Druck der Feder ΛΓ so lange mit der schrägen Fläche des Zapfens H in Berührung bleibt, bis er beim Niedergang der Wippe D durch Aufstofsen auf die Puppe O ausgehoben wird. Unterdefs ist aber auch der Zapfen G, ohne die Stimme nochmals zu berühren, wieder in seine erste Lage zurückgekehrt. The bridge B , in which the one-armed rocker D rotates in C, is screwed onto the rear end of the two-armed button A. This is pressed against the doll F by the spring E. On the rocker D a rubbing pin G and a pin H trimmed with leather are attached. . The keys are held down by the springs ρ ρ . If the key A is now pressed, the "rocker Z) rises, while it is pushed backwards by the doll F at the same time, Fig. 2. In this way, the pin G now matures the voice K , similar to the pin roller of a music box At the moment when the key hits the base L, Fig. 1, when it is depressed, i.e. the rocker is in the highest position, the pin H slides under the lever M, the latter through the pressure of the spring ΛΓ remains in contact with the inclined surface of the pin H until it is lifted by pushing up onto the doll O when the seesaw D descends. But also the pin G is again in its first position without touching the voice again returned.
Der Steg P, welcher sämmtliche Stimmen zwischen den beiden Eisenbacken Q. und R durch die Schrauben S festhält, ist durch die Schrauben T mit dem Resonanzboden U verbunden, und zwar so, dafs der Steg zwischen den fünf zur Befestigung desselben dienenden Schrauben ausgefräst ist, eine Berührung des Steges mit dem Resonanzboden also nur an fünf Punkten stattfindet, damit die Schwingungen des Bodens nicht gedämpft werden.The bridge P, which holds all the parts between the two iron cheeks Q. and R by the screws S , is connected to the soundboard U by the screws T in such a way that the bridge between the five screws used to fasten it is milled out, the bridge only touches the soundboard at five points so that the vibrations of the floor are not dampened.
Der Resonanzboden ruht an den Ecken auf Lagern; das Vorderbrett b, sowie die Rückwand c sind durchbrochen, so dafs der Ton genügend stark heraustreten kann. Auch kann eine Einrichtung zum Piano- und Fortespiel angebracht werden.The soundboard rests on bearings at the corners; the front board b and the back wall c are perforated so that the sound can emerge sufficiently strongly. A device for piano and fortes playing can also be attached.
