Another example of the earliest known
Seeburg coin accumulator mechanism, from style A #7,114 with
unknown brand of piano probably made in 1909. Each coin trips
the long lever that extends to the left, pushing the notched
vertical bar down one space. The shutoff perforation at the end
of each song trips the pneumatic, pushing the bar back up one
space, until the piano shuts off when the bar reaches the top
position.
