How to Make Electrical Machines / Containing Full Directions for Making Electrical Machines, Induction Coils, Dynamos, and Many Novel Toys to Be Worked by Electricity

The manual gives illustrated, practical instructions for constructing small electrical apparatus — including friction machines, induction coils, dynamos, and electrically driven toys — from commonly available materials. It guides the reader through building a base and supports, mounting a glass plate on an axle, assembling rubbing cushions, creating a foil-covered conductor with brass collectors and points, and attaching handles and terminals. The text also explains finishing details, alternatives for metal or wooden parts, and operational advice such as the importance of warmth and dryness for successful operation.
