ABSTRACT
A New York firm, successor to Sonora Chime Co., established in 1910. The company issued vertical-cut discs from May 1910, and also made record players for both vertical and lateral-cut discs. Victor sued them for violation, in the record players, of their old Berliner patent #534, 543 (covering the groove-driven stylus), and gained an injunction; the injunction was later vacated (and the patent expired in February 1911), but meanwhile Sonora went bankrupt. However, it reorganized, and was again offering the Sonora line of 11 models, at $45-1,000, by 1916. One model player had a “tone modifier”control. Jewel needles were provided. Another dispute with Victor in 1916, over the right to make an enclosed horn machine, was settled with Victor selling Sonora a license to continue.
