6 Claims. (Cl.A 134-377) This invention relates to improvements in wind instruments in the nature of harmonicas, mouth organs and the like.

An object of the invention is to provide an improved form of mouth organ or harmonica in which the selection of the notes and chords to be played is accomplished by iingering rather than by the usual manner of cooperative movement of the mouth and tongue over selected air discharge and intake openings communicating with individual reeds.

Another object of the invention is to provide an improved form of mouth organ or harmonica including a hollow harmonica body having a reed plate disposed therein, one face of the reed plate being in communication with a mouthpiece common to all reeds, and having a plurality of iinger holes in communication through individual ducts with the reeds on the other face of the reed plate, whereby, as air is caused to move into or out through said mouthpiece, only those reeds are actuated whose finger holes are unblocked by the iingers of the player.

A further object of the invention is to provide an improved form of mouth organ or harmonica including a pair of complementary body sections adapted to be joined along their opposed edges to form a hollow harmonica body, each body section being recessed to receive a portion of the edge of a reed plate disposed therebetween and thus dividing the interior chamber of the harmonica body into rst and second compartments on opposite sides of the reed plate, the body sections having -complementary extensions which when assembled definev a mouthpiece communicating with said first compartment, the second compartment being subdivided into sub-compartments communicating between each pair of inhaleexhale reeds and a linger hole corresponding thereto and formed in the exterior wall of the second compartment.

Still another object of the invention is to provide an improved form of mouth organ or harmonica which is so arranged as to be easily mastered by a novice, without the necessity for an extensive and costly course of instruction therein.

4A further object of the invention is to provide an improved and novel form of mouth organ or harmonica having the general external appearance in many respects similar to that of an Ocarina, but which is in reality a reed instrument Vwith individual interior reeds for each note.

Still another object of the invention is to provide a novel form of mouth organ which is simple in design, inexpensive to manufacture, and which is simple to use and provides good tonal quality.

Other objects and advantages of the invention Z Will become apparent from the following description of a preferred embodiment thereof as illustrated in the accompanying drawings, in which,

Figure 1 is a top plan view of my improved mouth organ,

Figure 2 is a sectional elevation taken on line 2 2 of Figure 1,

Figure 3 is a front elevational view of the instrument shown in Figure 1,

Figure 4 is a plan view taken on line 4--4 of Figure 3 and showing the bottom half of the mouth organ,

Figure 5 is a plan View taken on line 5--5 of Figure 3 and showing the upper half of the mouth organ, and

Figure 6 is a fragmentary sectional elevation taken on line 6 6 of Figure 3.

In the use of conventional types of harmonicas and mouth organs. it is necessary to learn a quite complicated system in which the mouth is moved along the entire length of the harmonica opposite the location of the particular notes to be played, and the tongue must be so disposed as to expose only the specic openings which communicate with the desired reeds. This manipulative technique is often a stumbling block to those who wish to learn how to play the harmonica, and frequently prevents them entirely from using this small, compact and companiable musical instrument.

The present invention makes it unnecessary to employ the mouth and tongue for locating the notes to be played, it being simply required that the player blow or draw upon the mouthpiece as needed, all location of the notes and chords being accomplished by means of the fingers. In order to understand clearly the nature of the invention and the best means for carrying it out, reference may now be had to the drawings, in which like numerals denote similar parts throughout the several views.

As shown, my improved mouth organ and harmonica includes a hollow housing or harmonica body generally indicated at I0, and formed of upper and lower complementary hollow portions l2 and I4 which mai7 for convenience be termed upper and lower halves, although they may not necessarily dividethe body Ill accurately in half. The lower body half I4 has a smoothly rounded external contour as shown, and the upper body half I2 is similarly rounded, so as to present no sharp or rough edges to the hand of the player and to comfortably iit his hand and mouth when in use. The harmonica body l0 may be formed of molded plastic material or other suitable substance. Y

Complementary upper and lower inner chamn of the upper body ihalf I2;

and lower halves I2 and I4 to come into mutual contact when assembled as in Figures .1, 2 and 3,7.

the halves being preferably secured together along their abutting edges by Acementorother-v 5 Wise to form a tight seal, as at 26.

The upper inner chamber I6 is divided by a number of lateral upstanding inner walls or par- 'titions 136, into `individual 'upper inner compa-rtments'v 62,' the spacing betweenadjacent inner partitionsL BQbeing such as toinclude-therebe 'tween one blow and one draw reed YSLi-"and 36, corresponding to two adjacent notes -inthe muvsioal scale covered by vthe harmonica. From Figure 5, it will be seen that eaeh-upperfinner compartment 32 communicates with the outer atmosphere through an individual ngering hole 38 which is formedin the upper wallrsurface 49 The upper portions of the ngeringholes 38 are divergently frusto=conicail,` as -see'n'lbest in Figures 1 and 2, -each being *encircled by anup standing annular rim @s2 which-is -thus-raised labove 4the surface Adfofthe'upper ibody 'ha-lf I 2, and is so proportioned-aste -allowfthe-jnger vtip of 'the "player to easily locate-'the ksame to as the player blows and draws upon the mouthpiece, the lower mouthpiece extension also being open at its left hand end as seen in Figure 2. It will be seen from Figure 2 that the Wall 44 blocks entrance of air directly into the upper compartments .32, and that when the Vplayer blows upon the mouthpiece, air lenters :the mouthpiece vestibule, flowing in the direction of the arrows 6E) into the lower chamber I8 and upwards through the reed plate slotI 52, into the upper ycompartment 32, causing the reed 34 to vibrate and to produce a musical sound. The air leaves the upper compartment 32 through the finger hole '38 as seen in Figure 2.

.It will 'be'apparent that when the player blows on themouthpiece, all the blow reeds 34 whose r fingeringY holes S are uncovered will vibrate to 'be placedthereon yto block the fingering holer n38 whendesired: VVThere areeight-fsuc'h fingering lholes 38,` arranged. as "shown'best in Figure Vl,
