This invention relates to improvements in pumping bellows such for example as are used in pneumatic musical instruments or la er attachments for musical instruments. he object ol' my invention is to provide a new and improved pumping bellows which is simple in construction, and easily and quickly adjusted for dilercnt capacities of wind;'according to the requirements oi the instrument.

I have here shown the bellows as double bellows that is two pairs ol bellows, and one bellows of each pair on eac-h side ol n central frame constitutings suction chamber l On the to of this frame standards 2 are secured in which a" crank shaft 3 is mounted which has two cranks 4. By means of a belt iulley 6 on the ond of this crank shaft anchaielt the crank shaft can be rotated lrom'b. motor 8", an electric motor being shown in the i'lraw- Vins. hTwo bellows 9 are mounted on ach si cof the suction chamber 1 and euch heb lows is provided at the swinging!V end of its movable boord with an upwardly projecting arm 1D, thcyarms 10 of two opposite bellows being connected by connecting rods 11 with a crank f1 of 'the shaft 3, so that'wlwn one bellows of two opposite bellows constituting bellows of one puh?,- is expanded, the other this pair is compressed. Each bellows is ork, have im ent"V Specification of )..ettms Patent.
