The purpose of the induction-coil is to raise the voltage of the battery. The flow of current must be an interrrupted one, in order to shock, and therefore

An Interrupter must be inserted between the battery and one of the wires leading to the primary-coil of the induction-coil. There are several ways to construct an interrupter, but the scheme which I have invented for the model of this shocking-machine (Fig. 187) serves the purpose nicely, and is a neat appearing little piece of apparatus. This interrupter is easily constructed as you will see by the working details shown in Figs. 194 to 198.
