Violet Ray Machine


By 1919, the Bleadon-Dun Co., of Chicago, was manufacturing various violet ray machines, all termed Violetta, and all delivering a high frequency ray that “Relieves Pain and Promotes Health.” The EMF Electrical Year Book for 1923 described Bleadon-Dun as “the world’s largest exclusive manufacturers of portable, one-piece, high frequency generators and equipment.” An inscription on this violet ray machine reads “Violetta . . . BLEADON-DUN . . .” A paper label in the lid carries a guarantee from the firm.
