Keyboard instrument.

Contrary to the previous practice, the strings are held in place during use or to stretch out standing musical works in the same horizontal plane (as with the pianoforte, the zither, etc.) or all of them The strings are to be arranged perpendicularly in a vertical plane (as with the so-called pianino) according to the present invention so arranged that they are horizontally in a vertical plane below run away from each other. And while the piano strings from extending their keys are cut at right angles, the direction lines cross in the new way mentioned When the strings are stretched out, the keys are usually in a horizontal plane, namely mostly right-angled.

This creates a graphical simplicity in the construction of stringed instruments a zither a means presented by a key several strings, z. B. for accords, at the same time to ripen. Another advantage is better utilization of the power of a stringed instrument occupied space and in view of all that a substantial reduction one of the manufacturing costs, not to mention the possibility of usable stringed instruments to be represented in such a diminutive detail that has hitherto been impossible at all had to appear.

In Figs. 1 to 6, an embodiment of the invention is illustrated which refers to their use in a zither and in particular as Peculiarity in general a key arrangement arranged at right angles to the zither having.

That the strings d respectively. d ^l d " ¹ spanned board (or the related plate) B stands wholly or almost at right angles on the base A supporting the keyboard α . The strings d run horizontally and their direction is crossed at right angles by that of the keys. Each key α sits one of the abstracts or bars b, provided with the noses c necessary for plucking the strings. These noses can be rotated around pins, but are usually in a position suitable for attacking by springs k placed against their rear, straight surface (Fig. 1 Below and above each string, the dampers e and f are attached. Between these, the string and the attack nose, the following interaction takes place with each plucking: If the key α belonging to one of the strings d is pressed, the rod moves with the rod b the nose c, which is supported in the same, against the lower damper e (Fig. 1), lifts this against the string (whereby its complete calming is achieved as well as a otherwise easily possible clink

is avoided), slides off the damper e again as it ascends and matures while the damper returns to its starting position, the string. Going up even further, the nose hits the upper damper /, folds it up (Fig. 2), so far that you can slide past it, and remains in the upper position (Fig. 3) as long as the key is kept depressed will. In doing so, the attack nose assumes a position above both dampers, and the string, which is in no way disruptive by the same, sounds. If the key is now released, the rod b goes back to the starting position (FIG. 1), supported by a spring / if necessary; while the nose c slides over the damper / away, which calms the string and, moreover, protects the string from touching the same as the nose passes (Fig. 4). Fig. 5 illustrates the front view of such upright zither; the slanted bridge g delimits the strings d and divides them, as it were, into two groups d1 dl. ... and d'2 d%. . . . These two groups find i.a. Also useful in the formation of chords by means of a key, through a suitable connection of the two groups of strings, as well as with the assistance of special abstracts or bars provided with several noses c. Such a, b \ is illustrated in the string view (Fig. 6), and in Fig. B. list the first four as such accord abstracts. The last staff (15) can also be used to form chords by means of a single key. If the instrument is set up as a pianoforte or pianino, the rod b (instead of using a ratchet nose c) acts on the horizontal by means of the hammer mechanism carried by the base lever (e.g. F in Fig. 1 of patent specification No. 65864) Strings arranged perpendicular to each other. Such an arrangement is illustrated by FIGS. 7, 8 and 9, and in addition to the hammer mechanism, a ratcheting mechanism is also provided so that, after prior adjustment, the strings can be ripped or struck as desired. From the keys α (Fig. 7 and 9) in front of or behind the vertical frame B1, which is strung with almost horizontally extending strings d, the abstracts or bars bl are vertically displaceable upwards until they become longer from left to right to enter the mechanism m for converting the vertical movement of the abstracts into an approximately horizontally swinging movement of the hammers η. When the keys α are struck, the abstracts b1 act on the hammer η with a foldable elbow ρ that can be adjusted by screws ο, in that the elbow, bumping against a projection q of the articulated hammer block r, sets the hammer in a swinging motion and makes it strike to the string d (Fig. 9). The hammer head, when located behind frame B, is passed through the soundboard. The damper / (see Fig. 8) is actuated by the now inclined abstract b (Fig. 9, dotted position) arranged on the other side of the frame B, which in this position does not touch the string with its attack nose c . If the hammer mechanism is to be set to rest and the attack mechanism is to be switched on, the angle piece ρ is turned over by screwing down the screw 0 (Fig. 9, dotted position) so that when the key α is struck it does not hit the projection q of the hammer block as before , but can move freely past it. As in the case described above, abstracts b are used to attack the string by means of nose e, which can be adjusted by screw s, with damper f being actuated as well as when the hammer mechanism is switched on.
