Grainger's 'Free Music'
Kangaroo pouch machine in the Grainger Musuem, showing the transport rolls and paper cutouts. Grainger wrote about it in 1952:
" 8 oscillators, able to play the gliding tones and irregular (beatless) rythms of Graingers FREE MUSIC (first thought of around 1892), are manipulated by paper graphs, towered discs and metal arms.A sheet of light brown wrapping paper 80 inches high (called "main paper"), is rolled continually from the "Feeder" revolving turret into the "Eater" revolving turret, passing through a metal cage on its way (the cage keeps the Main Paper, the graphs and ths discs in place)...."
