“On This Day in the History of Recorded Sound…”

May 24, 1892: Leon F. Douglass was granted a U.S. patent (No.475,490) for “Method of and Means for Duplicating or Transferring Phonographic Records.” This involved simply attaching the reproducer of one phonograph to the recorder of another phonograph with a squeezed rubber tube, resulting in a slight vacuum.

May 24, 1906: Paul Berner filed for a U.S. Design Patent (eventually granted as No.38,275) for “Phonograph Horn.” This became the “Searchlight” horn, manufactured for cylinder and disc talking machines.
