DEVICE FOR GIVING CORRECT NOTES AN D HARMONIESIN MOUTH ORGANS Application filed August 23, 1926,.Serial No. 130,852, and in Germany May 12, 1926.

The present invention relates to an improvement on the existing devices for giving correct notes and chords in mouth organs, in which av mouthpiece is provided on the one hand and a slide provided with holes on the other in order to enable the desired combination of notes to be produced. Ac cording to the present invention this device is considerably simplified in that the mouthpiece and slide are in one piece so that the desired note can be readily and accurately adjusted and produced with certainty. Given a suitable arrangement of the notes,

that is, a suitable arrangement or formation of the blowing orifices, .the device can also serve as a harmonizer.

The new device .is characterized not only by its simplicity of construction and superior adjustability, but also by economy of material and increased possibilities of application. Its construction also adapts" it for mass production by machinery. Finally the instruments are strongerthan those hitherto known. i

A typical embodiment of the subject of the present invention is more 'fully illustrated in the drawing Figures 1 and 2 are respectively a front elevation and plan of the instrument.

Figures 3 and 4 are an end elevation and cross section of the same.

Figure 5 is a bottom'view, and Figure 6 shows on a much larger scale a bottom view of the braking spring arrangement of the mouthpiece.

The instrument is a kind of mouth organ the reeds a of which are situated as usual in or above the holes of the mouth board 6 and are caused to sound by blowing or suction. They are enclosed in a sounding or protective casing 0 made in the usual manner which is legibly impressed with a scale of notes (5 corresponding to the range of the instrument and also with the lettering e of the notes.

The blowing side otthe instrument is provided with a strip f provided with blowing.

apertures 1 corresponding to the chambers in which the reeds are located. This strip also serves as aguidc for the sliding mouthpiece h which also serves as an adjusting slide, and is provided with blowing aperlures 2'. The mouthpiece h embraces the guide strip by means of its edges 72:, which are suitably bent round over strip f so that lapping portion k of the mouthpiece h and its ends bear elastically against the adjacent wall ofthcguide strip The spring Z is held by claws m provided on the bent over portion 7a of the mouthpiece 7:, which grip it in such a manner that it is curved and pressed against the correspond-. 111g guide wall of the guide bar This provides a simple method of mountmg the spring-Z and all springs used in such devices are mechanically placed under identical and correct tension.

To facilitate sliding the mouthpiece h Small upward bends n are provided at both ends of same.

lln addition means are provided to stop the mouthpiece in its two lateral terminal positions and prevent it from being pushed too far or from being accidentally slid off the instrument altogether. \Vith this object the blowing side of the cell panel I; is provided with stops for example, in the form'of small screws 0 and the mouthpiece h is provided with slots 29 extending so far into the bends n that the head of the stop screw 0 can engage in the slot .17 the end of which limits the movement of its mouthpiece h by coming in contact with the screw 0.

On the upper side a pointer g projecting from the mouthpiece 71. moves over the'charactors e relating to the notes, and thus facilitates correct adjustment for/the notes.

The number, position, dimensions and shape of the blowing. apertures 2' in the mouthpiece may be varied to any extent.

Hence, the combination of the apertures z,

the notations e, and the pointer 9, enable a person without musical training to readily sound suitable chords and harmonies. I am aware of the fact that slidable mouthpieces for harmonicas have been previously proposed, but such mouthpieces did not operate to enable chords and harmonies to be sounded.

What I claim is 1. A month organ comprising a body portion having a front edge provided with openings correspolnling to the chambers in which the reeds of said mouth organ are located, a guide strip connected to said front face and having apertures corresponding to said chambers, said guide strip having angular projecting portions above and below the said front face, a mouthpiece having angular inturned portions slidablv engaging the angular projections of the said guide strip, said mouthpiece having associated therewith a spring adapted to slidably and frietionally bear against the said mouth organ.

2. A mouth organ comprising a body portion having a front face provided with openings corresponding to the chambers in which the reeds of said mouth organ are located, a guide strip connected to said front edge and having openings aligned with said chambers, said guide strip having angular projecting portions above and below said trout face, a mouthpiece having inturned angular portions engaging the said angular projecting portions of the guide strip, and a curved blade spring connected to the said mouthpiece the ends of the said blade spring being adapted to frietionally bear against one of said angular projecting portions.

In testimony whereof I afiix my signature.
