William F. Craddock et al of Chicago received U.S. patent no. 1,456,223 for "Electrical blanket and the like" on 22 May 1923.
In advertisements of the time, Vit-O-Net was billed as a "health garment" that, through magnetic wires, would draw poisons
out of the body and "stimulate new life." In the annual report of the Federal Trade Commission for 1930-1931, docket 1679,
an order entered 7 July 1930, required the Vit-O-Net Corporation, engaged in the manufadcture of an electric blanket designated
the 'Vit-O-Net,' to cease and desist from representing that such blanket is endorsed or recommended by prominent physicians,
scientists, etc., and that it has any therapeutic value except as a heating pad."
