Seller: fizzbombsmother (9,064) 99.3%, Location: Colorado Springs, Colorado, Ships to: US, Item: 383239944793 This is some old equipment! It is nearly 100 years old!! This is an old Master Appliances Violet Ray Machine, which first appeared in the 1920's. If you are as crazy as me, you can plug it in and watch it work. I do NOT recommend that, this machine and the CORD are VERY VERY old! This comes from Wikipedia: Their basic construction was invented prior to 1900 by Nikola Tesla, who introduced his first prototypes at the World's Columbian Exposition in 1893. Most of the antique violet rays in the US were produced before the Depression era, and some of the larger US manufacturers of violet rays were Renulife, Fitzgerald, and Fisher. Companies who manufactured violet ray devices made many other types of electrical appliances as well, e.g. Star Electric, which also manufactured stock ticker machines. Many of the companies who were able to continue manufacturing violet rays after the Depression stopped making them due to World War II, when they began manufacturing radio coils and other electrical components for the war instead. A typical violet ray device consisted of an ungrounded, electrical control box that controlled the interrupter and housed the magneto coil, and an attached bakelite or other handle housing which contained the high voltage coil and an insertion port for attachments. Glass, evacuated tubes of varying shapes and for different therapeutic uses could be inserted into the bakelite handle to apply the resulting current to different parts of the body. Violet ray treatments were said to cure everything from lumbago to carbuncles. Shipping by USPS Priority Mail. Thanks for looking!!
