US Patent 1752978

Awarded in 1930 to Henry O. Drotning of New York, this appears to be the patent for the Playasax (also written as Play-a-Sax), made by the QRS DeVry Company of Chicago. As well as this saxophone-shaped instrument, they also made the Clarola, which was modeled after a clarinet. With both of them, the player simply blew into the mouthpiece and turned a handle which drew a paper music roll over a harmonica mounted in the body of the instrument.

Here is a page with further information on the Playasax:

QRS DeVry also made photographic equipment and Drotning was awarded several patents for camera-related designs owned by the Kodak Eastman Co.
