By attaching a set of clockworks in the same manner as described for the automobiles, you can make
A Clockwork Railway, constructing the cars similar to the street car shown in [Fig. 84], Chapter VI, and using the schemes in the same chapter for the tracks and depots.
Each car should be provided with a clockwork motor, because a single clockwork is not strong enough to pull more than one car. Let me know how you succeed in building a clockwork railway.
[CHAPTER XI]
HOME-MADE ELECTRICAL TOYS
An entire volume might be filled with plans for electrical toys and yet not exhaust the innumerable forms that are within the ability of a boy to construct. There is room in this chapter for only a few, and I have selected simple ideas, those that can be carried out by a boy having no knowledge of working with electricity, with materials that can be obtained at an expenditure of little or nothing. Thus every boy will be able to make these electrical toys.
The Electro-magnet Derrick shown in [Fig. 176] will hoist nails and other small pieces of hardware from the floor to a table top, and as the boom, or arm, can be swung from side to side, and raised and lowered, loads can be moved from place to place in the same way as with large derricks. The toy derrick may be used for loading and unloading toy wagons, carts, and trains of cars, provided, of course, you use iron or steel of some sort for your loads. It is easy enough to get nails, brads, tacks, and odd pieces of hardware for the purpose. The model from which [Fig. 176] was made has lifted a bunch of two hundred and eighty-four brads 3/8 inch long. By using smaller brads, or tacks, a much larger number could be lifted.
