the performer -upon the piano or other musical instrument to turn the music leaves withouttaking his attention from `his work and without losing a beat in hisperformance.

The invent-ion `consists inthe use of a' pedalv ,operated pneumatic or bulb, in ,confY nection with' an air propelled reciprocating or oscillating member, and automatically acting leaf turnin mechanism automatically The invention further .comprises Y bination and arrangement of parts and'construction of details ashereinafter described, -shown in the ac companyin Adrawings and specifically pointed out in t e c1aims2 In the accompanying drawings, Figure 1 is la perspective .iewof the device, show-.1

ing the manner of its application to a piano. The bulb and rubber tubing are laid upon the top of the piano case, but in use the l -hulb lies on the floor where it is accessible to the foot of the player; Fig, 2 is avertical longitudinal section. of the compressedjair cylinder showing` the connection with the .air tube and the piston 'therein which controlsthe movements of theI leaf. turnin view of the stop plate andstops thereon.

In these viewsl is a metal air tube'whic'h lis. preferably attached to the piano case or oth'rz-,'i'nstrument, atthe rearso as not to deface the woodwork.
