MENZENHAUER & SCHMIDT in BERLIN. Klavierzither. MENZENHAUER & SCHMIDT in BERLIN. Piano zither.

Patentirt im Deutschen Reiche vom 16. Januar 1901 ab.Patented in the German Empire on January 16, 1901.

Vorliegende Erfindung betrifft eine Klavierzither, d. h. eine Zither, deren Anreifser durch Anschlagen von über den Saiten angeordneten, eine Klaviatur bildenden Tasten in Thätigkeit gesetzt werden.The present invention relates to a piano zither; H. a zither, the attacker through Striking of keys arranged above the strings, forming a keyboard, in action be set.

Um eine unmittelbare Verbindung der Anreifser mit den Tasten zu ermöglichen, ohne die Tonentfaltung zu beeinträchtigen, sind die mit Nasen zum Anreifsen der Saiten versehenen Anreifser derart drehbar gelagert, dafs sie beim Niederdrücken dem von der Saite von unten her auf ihre Nase ausgeübten Druck nicht nachzugeben vermögen, dafs sie sich dagegen um ihren Drehzapfen drehen können, wenn die Saite beim Rückgange von oben her sich gegen die Nase legt, wobei die Rückkehr des Anreifsers in die Ruhelage durch Federn gesichert wird.In order to enable the attackers to be directly connected to the keys without Impairing the development of the tone are those provided with noses for attacking the strings The attacker is rotatably mounted in such a way that, when it is pressed down, it pulls the string from below The pressure exerted on her nose cannot give in, so that she opposes it can turn around its pivot when the string is moving backwards from above puts against the nose, the return of the attacker to the rest position secured by springs will.

Damit die Saite bei der Berührung mit dem Anreifser während der Rückkehr des letzteren in die Ruhelage nicht klirrt, trägt der Anreifser auf der oberen Seite seiner Nase einen Dämpfer aus Filz oder dergl.So that the string in contact with the attacker during the return of the latter does not clink in the rest position, the attacker wears a on the upper side of his nose Dampers made of felt or the like.

Eine der Erfindung gemäfs gebaute Zither ist auf der Zeichnung dargestellt.A zither built according to the invention is shown in the drawing.

Fig. ι zeigt die Zither im Grundrifs. Fig. 2 ist ein senkrechter Durchschnitt durch das Instrument, parallel zu einer Saite. Fig. 3 ist ein senkrechter Querschnitt durch eine mit zwei Anreifsern ausgerüstete Taste. Fig. 4, 5,6 und 7 sind senkrechte Querschnitte durch eine mit einem Anreifser ausgerüstete Taste, welche den Anreifser in verschiedenen Stellungen vor und nach dem Anreifsen einer Saite zeigen.Fig. Ι shows the zither in the basic riff. Fig. 2 is a vertical section through the Instrument, parallel to a string. Fig. 3 is a vertical cross section through a with two attackers equipped key. Figs. 4, 5, 6 and 7 are vertical cross-sections through a equipped with an attacker button, which the attacker in different positions and show after touching a string.

Der Resonanzboden der Zither ist mit α bezeichnet. An dem vorderen Ende der Zither erstreckt sich quer über den Resonanzboden oberhalb der Saiten b eine Brücke c. Die Saiten b sind an dem vorderen Ende des Instrumentes in bekannter Weise vermittelst Befestigungsstifte d befestigt und gehen über einen Steg f und dann zu den Wirbeln e am hinteren Ende des. Instrumentes. Unter der Brücke c befindet sich eine die Tasten g tragende Schiene /?, welche an ihren Enden von dem Resonanzboden getragen wird. Die Tasten g sind an ihrem hinteren Ende drehbar an der Schiene h gelagert und stehen unter dem Einflufs von an der Schiene h befestigten Federn z, welche dieselben in erhobener Stellung zu halten streben und gegen die Filzplatte j auf der Unterseite der Brücke c drücken (vergl. Fig. 2). Die Tasten g sind in Schlitze der Schiene h eingesetzt und sitzen auf einem Draht k, der auf der Schiene h durch vermittelst Schrauben / an der Schiene befestigte Winkel m festgehalten wird.The zither's soundboard is labeled α. At the front end of the zither, a bridge c extends across the soundboard above the strings b. The strings b are attached to the front end of the instrument in a known manner by means of fastening pins d and go over a web f and then to the vertebrae e at the rear end of the instrument. Under the bridge c there is a rail /? Which carries the keys g and which is carried at its ends by the soundboard. The keys g are rotatably mounted at their rear end on the rail h and are under the influence of springs z attached to the rail h , which strive to hold them in the raised position and press against the felt plate j on the underside of the bridge c (cf. . Fig. 2). The keys g are inserted into slots in the rail h and sit on a wire k, which is held on the rail h by means of screws / brackets m fastened to the rail.

Das äufsere, d. i. das vordere Ende des Tastenhebels ist schwächer als der mittlere Theil und bildet die eigentlichen Tasten. Es wird zweckmäfsig auf der Unterseite mit einem Filzstreifen η bekleidet. Der gewölbte Mitteltheil 0 jeder Taste trägt zweckmäfsig die Bezeichnung des Tones der beim Anschlagen der betreffenden Taste angerissenen Saite oder eine sonstige Bezeichnung für diesen Ton. Eine Anschlagleiste p, welche unterhalb des vorderen Endes der Tasten in geeigneter Weise be-The outer, that is, the front end of the key lever is weaker than the middle part and forms the actual keys. It is suitably covered with a felt strip η on the underside. The arched middle part 0 of each key expediently bears the designation of the tone of the string that was torn when the relevant key was struck, or some other designation for this tone. A stop bar p, which is placed below the front end of the keys in a suitable manner

Claims

and is covered with a felt strip q, is used to limit the movement of the keys when the keys are struck. Each key lever is provided on its lower side with two lugs r, through which a pin s is inserted. Each pin s serves as a pivot for an attacker. The attacker t is expediently bent from a single strip of sheet metal in such a way that a part of the nose u, which causes the attack of the string, sits between two vertical arms ν w, of which one ν ends in a sleeve seated on the pin s, while the other w is under the influence of a spring χ which returns the attacker to its rest position as soon as it has passed the side of the instrument on its upward movement. The attacker's nose u is provided with a felt covering on its upper string, which acts as a damper if the attacker hits the string during its upward movement, Fig. 7. The cavity enclosed by the attacker's nose u is filled with a felt insert to make the attacker elastic. The keys, which are assigned to the accord strings, are expediently equipped with two attackers to attack two strings at the same time, Fig. 3 When the instrument is to be played, the keys on the right side, which are assigned to the melody strings, are struck so that the melody of the piece sounds while the keys assigned to the accord strings are struck either simultaneously or alternately with the keys of the melody strings. During the downward movement of a key, the inclined end of the nose of its attacker slides over the string and, since the attacker does not move sideways when descending, causes the string to attack until it finally steps under the string. The return of the key lever to the rest position is carried out by the spring z, while at the same time the nose of the attacker is lifted over the string. The various positions of the attacker with respect to the string are shown in FIGS. During the upward movement of the key, the damper y comes into contact with the string and attenuates its tone. At the same time the attacker swings around its pivot so that the nose can pass the string; here the attacker's arm w emerges from its rest position and tensions the spring x which, after the nose has passed the string, returns it to the rest position. The arrangement described offers the advantage that a zither or an instrument similar to a piano can be played by anyone who knows how to play the latter instrument, and that at the same time a fuller sound is obtained than when the zither is played with the aid of the usual plectrum . Patent-A ν Proverbs:

1. Piano zither with attackers rotatably mounted on the keys, characterized in that the attackers (t) are mounted in lugs (r) on the lower side of the keys (g) and after the strings have been attacked by springs (x ) must be returned to the initial position.

2. Piano zither according to claim 1, characterized in that the attacker consists of two angles which are connected to one another by a web and which, under certain circumstances, consist of a single strip of sheet metal, the legs of which are connected to one another form a nose for attacking the string, while from the free legs of which one is rotatable about a pin (s) arranged on the key lever, and the second is under the influence of a spring (x) which is tensioned when the key is opened when the pressure of the string on the nose (u) at the _T bends to the side reifsers the same and then, returns after release of the nose (u) through the string, the Anreifser in its rest position.
