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 made of mostly of brass gears with a heavy brass frame housing. To use, one would connect two metallic cords in the ends of the box, and apply the other ends of the cords with the brass handles to any 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 generated an electric current from spinning magnets which sent a small shock to surprised and delighted patients suffering from any number of nervous disorders The box and mechanism are complete and in excellent condition and the device is in good working condition as well. All parts appear to be original. The inside of the box lid has the original Davis & Kidder Directions sheet. Dimensions are 10" x 4.5" x 4.5".
