PATENT LETTERING

CLASS 51: Musical instruments.

Patented in the German Empire on May 6, 1897.

The extremely simple attacking device for zithers, mandolins, guitars, in general for stringed instruments that are played by touching the strings are generally characterized by comfortable, easy-to-learn handling. Special benefits are the option to have the tone sound only once or several times in quick succession, whichever The latter style of playing results in a mandolin-like tremolando playing on the accord zither not at all, on the concert zither can only be achieved with a certain skill; furthermore the simple, so to speak natural, control of the pitch; then the ease with which Individual tones or chords can be played as required. These properties If they do not result from the description automatically, they are more suitable Position must be proven.

An accord zither is assumed in the drawing; H. one at which there is a special string for every tone that can be produced on the instrument is, in contrast to the concert zither with its fingerboard strings. The device can also be used with instruments of the latter type be applied.

Fig. 1 is a view from above, Fig. 2 partly vertical cross-section, partly view from the front, FIG. 3 is a vertical longitudinal section (in the sense of the string direction), FIG Special representation of a key fog with a finger.

Across the strings or a part of the stringing (if not all strings of the instrument to be touched by the apparatus), the bar extending through the pins A. α guided vertically, it rests on elastically compressible pad; rubber buffers α ¹ are drawn, through which the pins α pass. The latter are fastened in a suitable manner on the ceiling B of the instrument.

On the flanks of the beam, the key levers CC swing at cc , one for each string to be gripped by the device. Because of the limited space they are distributed on both sides of the beam in such a way that the levers for the 1st, 3rd, 5th ... string on one, the levers for the 2nd, 4th, 6th ... The string on the other side. Each lever has a (expediently hollowed out, as in Fig. 4) key top; a (expediently elastic) finger c ¹ made of a material that must not sound or rattle, preferably hard rubber, is inserted into the lower arm.

The key levers require a stroke limitation by fixed stops, which, according to the drawing, is formed by the slotted cover e of a cladding E. The latter must of course be open at the bottom and allow the strings to pass freely. An extension of the beam can protrude from the cladding on one side (Fig. 1 and 2 on the right).

The vertical distance between the bar and the strings is measured so that when the fingers c ¹ do not touch the strings when the levers vibrate, or only touch them very slightly (pianissimo playing). By lengthening the bar it can be depressed

if you want to get a stronger sound; however, this can also be done using the button lever happen even when attacking.

The attacking takes place, if you want to sound the relevant note only once, by moving the relevant key lever from one end position (determined by the slot in e ) to the other. The finger c ¹ strokes the string (Fig. 2, left terminal lever, and Fig. 4), bends it a little and lets it snap off, so that it starts to vibrate. The lever then simply remains in the new position until it is brought back into the initial position the next time the string is touched.

It is different with the mandolin-like game. The key lever is quickly moved back and forth so that it passes over the string several times in quick succession, which is now emits several briefly interrupted tones, because with each new attack one The previous vibrations are interrupted.

Through the key lever that is equally effective when going back and forth thus achieves that the strings either simply or quickly one behind the other (mandolin-like) can be touched; In addition, such arrangements are made dispensable, which would have to make the decrease of the lever ineffective.

With regard to the regulation of the tone intensity by the key levers themselves, it should be noted that if you intend to play forte, you will press the key tops with greater force of your own accord; this would happen involuntarily, even if greater pressure were not necessary for a stronger game. But since, depending on the magnitude of the pressure, the bar A lowers accordingly and the string is torn more forcefully, one can rightly call this type of control of the tone strength a natural one that is not difficult to learn.

Claims (1)

Patent claim: A rigging device for stringed instruments, characterized in that on a bar (A) that extends across the strings or a part of the strings, is supported on elastic supports (a ¹ ) and can be depressed perpendicular to the strings, two-armed button levers (C) with gripping fingers (c ¹ ) are rotatably mounted, which, limited in their movement by stops (e) , can attack the string when they vibrate in both directions and therefore the tone once when pushed over from one end position to the other, but the tone when moving back and forth Let the tone sound several times (like a mandolin), whereby the pressure exerted when moving the levers can also be used to regulate the strength of the attack. 1 sheet of drawings.
