PNEUMATICALLY PLAYI NG ACCORDION Filed Nov 10, 1950 2 Sheets-Sheet 2' Patented Nov. 5, 1935 UNITED STATES PATENT OFFICE Application November 10, 1930, Serial No. 494,648 In Germany November 23, 1929 4 Claims.

The present invention relates to self-acting musical instruments, such as accordions, bandonions, and the like, and consists in providing the instruments, without altering materially their external shape and combination, with an inside pneumatic or electric player controlled by a strip of music and adapted to release the reed plates, sound being produced as in a normal instrument by moving the bellows to and fro by hand. The reed plates are disposed in the usual manner in both parts of the instruments, as are the releasing devices which act upon the reed plates, and the constant playing wind required is produced by treadle or motor independently of the instrument. The releasing device arranged in both the bass and treble part is controlled by a common music band, the conveying device of which is located in the bass or treble portion of the accordion or other instrument concerned. However, if the dynamic records on the music band are to be followed durlng playing, the music transporting device may be arranged also on the bass or treble portion of the instrument.

The conveying device for the music band may be arranged also at a distance from the instrument and the reed plates released by remote control by connecting, for example, the instrument in a suitable manner with another self-playing one. In this case the instruments must be fitted with suitable devices for the pneumatic or electric release of the reed plates of the instrument, such as an accordion, which would be made to sound by moving the bellows to and fro.

A portable accordion of this type enables everyone to play any music and, by moving the bellows to and fro, to vary the character of the music according to ones own mood while the reed plates are actuated by the pneumatic device inside the instrument.

Two forms of the invention are illustrated in the accompanying drawings, in which views of partly opened accordions constructed according to the invention are shown.

Referring to the drawings, a is the treble portion, b, the bass portion; 0, the accordion bellows; d, the box for the music conveying device; e, e' are the reed plates with their sounding tongues in the treble and bass portions (1 and b; f, the wind chests; and g, the small bellows releasing the keys. h is the sliding block to which the hoses i, i leading to the wind chests j are connected, 7' the rollers and l the music strip passing by the slide block from one roller to the other. The driving means for the rollers, which may be a spring work and also located in the box (1 has not been shown. The lengths of hose 1" leading to the bass portion are arranged side by side so as,

to form a band. In this way the hose remains perfectly mobile and breaks at the bending points are prevented, the length of the band being chosen so as not to interfere with the motion of the accordion bellows. The air piping from the blower to feed the wind chests f, ,f is connected to the branch is.

Whilst in Fig. l the controlling mechanism comprising the sliding block h, the rollers j and the music strip 1 is mounted inside the accordion, the same is arranged outside the accordion in Fig. 2 and the hoses i are leading from outside to the wind chests f inside the accordion.

I claim:

1. In an accordion, a pneumatic action inside the instrument for actuating the flaps of the reeds, a tracker bar in connection with the pneumatic action, a tuning roll of paper passing over the tracker bar, driving means for the tuning roll and a pumping mechanism for supplying air to the pneumatic action.

2. In an accordion having a bass and a treble portion, a pneumatic action inside of each portion for actuating the flaps of the reeds of said portion, a tracker bar in one of the portions in connection with the pneumatic actions of both portions, a multitubular hose-band connecting the tracker bar with the pneumatic action in the opposite portion, a tuning roll of paper passing over the tracker bar, driving means for the roll and a pumping mechanism supplying air to the pneumatic actions.

3. In an accordion having playing bellows for making the reeds sound, a pneumatic action for actuating the flaps of the reeds, a tracker bar in connection with said pneumatic action, a tuning roll of paper passing over the tracker bar, driving means for the roll and a pumping mechanism supplying air to the pneumatic action independently from the wind produced by the accordion playing bellows.

4. In an accordion, a pneumatic action inside the instrument for actuating the flaps of the reeds, a controlling mechanism for the pneumatic action outside the accordion, means for establishing connection between said controlling mechanism and the pneumatic action in the accordion and a pumping mechanism for supplying air to the pneumatic action.
