phonogfp Posted March 13, 2021 Posted March 13, 2021 "On This Day in Phonographic History..." March13, 1906: Eldridge Johnson was granted a U.S. patent (No.814,786) for a tapering tone arm. The acoustic improvement over the short-lived “Rigid Arm” (introduced in October 1902) was noticeable, and the ingenious goose-neck sound box tube would distinguish Victor’s products for decades to come. #antiquephonographsociety #phonograph #gramophone #antique 1
