A doctor’s medical apparatus first developed in the late 1800’s used to administer mild electrical shocks to their patients. Electricity was a new phenomenon at the time and people believed that small amounts of electrical shock could cure everything from Nervous diseases to toothaches. Enclosed in a well-constructed solid wooden box this is a remarkable antique device. To use, one would connect two cloth covered cords in the ends of the box, and apply the other ends of the cords with the brass handles to the part of the body through which it is desirable to pass the current of electricity. Turning the crank will produce a mild current while the knob at the end of the box will control the intensity. It generates an electric current from spinning magnets which sends a small shock to the patients suffering from any number of nervous disorders The box and mechanism are complete and in excellent condition and good working condition as well. All parts appear to be original. The inside of the box lid has the original manufacturer sheet, Manufactured by Miller Lighting Rod Company in St. Louis MO.. Dimensions are 10" x 4.5" x 4.5".
