Some Oddball Phonograph Patents (1902 – 1906)

This bizarre phonograph, employing a record and turntable in the form of a truncated cone, was patented by Louis P. Valiquet, of Zonophone fame. One advantage was said to be that the record was less likely to slip on the turntable than a standard flat disc.

Emile Berliner’s device for increasing volume, employing six synchronized turntables. A later “improvement” stacked the turntables vertically.

F. F. Shanks of Chicago patented this reproducer-less device consisting of an extended rod that carried the sound vibrations directly from the stylus to an attachment of the user’s choosing (the filing mentions a snare-drum head, banjo, or other stringed instrument), which served as a resonator.

A more direct approach to musical-instrument-as reproducer, in this case a complete violin. A version of this machine was actually manufactured in France.

For when the “just stuff a sock in it” approach won’t do, here’s a  marvelous piece of German over-engineering. This sadistic-looking device was patented by Albert Conze of Berlin and specified a muffler-ball of leather, cork, or felt. Edison later employed the same general idea in his Diamond Disc machines, but with the adjusting mechanism neatly tucked away below the bedplate.

Vintage Phonograph Gallery • The Kraemer (Hawthorne & Sheble) Spring-Loaded Tone Arm (1907)

Thomas Kraemer’s spring-loaded tone arm was featured on Hawthorne & Sheble’s Star phonographs beginning in 1907. A key feature was a small coiled spring that was said to propel the reproducer, thus supposedly skirting Victor’s Berliner patent, which specified that the record groove served that purpose. The courts weren’t swayed by that argument, finding the spring was too weak to serve any real purpose. Victor eventually forced Hawthorne & Sheble into bankruptcy, over unrelated patent-infringement claims in the Starola enclosed-horn machines, in 1909. There’s much more on Hawthorne & Sheble in A Phonograph in Every Home, available from Mainspring Press and many major libraries.
