6 Claims.

This invention relates to a stringed musical instrument of the Zither type, consisting of a relatively flat resonance box over which are mounted a series of strings, this instrument having attached thereto a playing mechanism similar to a piano action and a removable case which encloses the instrument and playing mechanism, the case having an aperture therein through which the keys are exposed for access.

The ordinary Zither usually includes a relatively ilat resonance box which is rectangular in shape except for one corner which is slabbed oi so that the resulting contour is somewhat suggestive of the shape of a grand piano.

According to the present invention, a playing mechanism including a series of hammers and a. series of playing keys for operating the hammers is removably secured to the instrument at the base end thereof so as to project beyond the base end. A casing or housing is removably secured to the instrument in such a way as to enclose it as well as the playing mechanism, this housing being shaped somewhat like a grand piano case. Preferably the housing includes a hinged cover portion with a prop for holding it in raised position so as to resemble a grand piano with its top open.

It is an object of the present invention to combine with a Zither or similar instrument a simple piano action and a casing to house the Zither and action so as to expose the playing keys of the action, the result of this combination being a toy-sized grand piano. The casing and the playing mechanism are preferably removable from the zither so that the Zither can readily be tuned or played as usual.

For a more complete understanding of the invention, reference may be had to the following description thereof and to the drawing of which Figure 1 is a plan view of an instrument embodying the invention, a portion of the top being broken away.

Figure 2 is a side elevation of the instrument shown in Figure 1.

Figure 3 is a section on ure l.

Figure 4 is a fragmentary plan view of a portion of the structure shown in Figure 3.

Figure 5 is a partial side elevation of a modied form of playing mechanism for a Zither.

As indicated in Figure 1, a Zither I0 of the usual kind, or a similar instrument, may be mounted in a housing which includes side walls the line 3 3 of Fig- 'l2 and i4, a base end wall I6, and a top I8. A

portion of the top 20 is hinged as at 22 to the side wall l2 so that it can be swung from its normal horizontal position. A suitable prop (not shown) is provided to hold the cover portion in its raised position. The upper portion of the end wall I6 is oiset as at 24, leaving an aperture in the casing through which are exposed the white keys and the black keys 32 of a playing mechanism for the instrument I0. The housing comprises two separable parts and is removably secured to the Zither and playing mechanism as by a few screws or bolts 33. Thus the rear section of the housing can be removed for tuning the instrument without disturbing the alinement of the keyboard section. The playing mechanism is illustrated in Figure 3 and comprises a pair of end frames 34 which of the Zither. Extending between the frames 34 are

rails

38, 40, 42 and 44. Also extending between the end frames 34 are

rods

46, 48 and 50. The rod 46 serves as a pivot element about which the white keys 30 rock. The rod 48 is a pivot element on which the black keys 32 rock. The rod 50 is a pivot element on which a series of hammers 52 rock. Each of these hammers consists of a normally horizontal lever rockable on the pivot member 50 so as to strike a corresponding string on the Zither l0. To this end, each hammer may be provided with a suitable felt 54 in its striking end. The opposite end of each hammer rests on a felt pad 56 mounted on the adjacent end of the corresponding key which is overlapped by the end of the hammer. A series of leaf springs 60 are mounted on the end portions of the hammers so as to hold the hammers resiliently in their normal horizontal position. The action thus consists principally of a pair of simple levers having overlapping end portions, so that, when the key is rocked by finger pressure, it in turn rocks the corresponding hammer against the pressure of the leaf spring so as to cause the felt 54 to strike one of the strings of the Zither. The rail 42 is surmounted by a strip 62 of felt which acts as a stop member to determine the normal positions of the keys and hence of the hammers. The rocking movement of the white keys 30 is limited of the rail 38. In like manner, the rocking 32 is limited by a strip of felt 65 mounted on the upper edge of the rail 40.

Ii desired, each key may be provided with a damper 63 which has end 'felt lil normally in contact with the corresponding string of the Zither when the key is in its normal horizontal position. When the key is struck, the damper 68 is elevated with the end portion oi the key to which it is attached, thus moving its felt 'd out or" contact with the string just prior to the impact of the han `-ner on the string. rEhe foregoing piano action is simple in structure and easy to manufacture and assemble.

A modified form of action is illustrated in Figure 5. As therein shown, the Zither l0 is supported in an elevated inverted position. To the Zither is secured at the base end thereof a pair of end frames Bil which extend beyond the base end of the Zither and support a piano action for striking the strings of the Zither. This action consists of a series of hammers 82 is pivoted as at B4 to rock upward so as to strike the strings or the Zither. Each hammer is 'provided with a capstan 8S bearing against the under face of a key 3U or 32. These keys are pivoted respectively on pivot elements 6,6 and 43 as hereinbefore described. Suitable stop elements 52, i4 and (i5 are mounted on rails which extend between the end frames 80 to limit the rocking movement oi the keys in the manner described in connection with Figure 3. Owing to the position or the pivot elem-ent Sil about which the hammers 8'! rock, the hammers are held by gravity in their normal inactive position from which they are rocked when the corresponding keys are struck.

The casing shown in Figures l and 2 may be decorated as desired to imitate more closely the appearance of a grand piano. A removable music rack 5t may be mounted on the top of the casing, and, if desired, legs (not shown) may be attached to the casing.

It is evident that various modiiications and changes may be made in the specific embodiments of the invention herein shown and described without departing from the spirit or scope of the invention as defined in the following claims.

We claim:
