The general arrangement of a Westinghouse electric brake commonly used in trolleys at the turn of the century. (a) and (a') are the track shoes, (b) and (b') are the brake shoes, (c) is the magnetizing coil that receives current from motors running temporarily as generators, (d) and (d') are springs that the brakes are suspended from, and (e), (k), (h), and (f) are levers that assist with the movement of the brake system.

Image of a Westinghouse circuit breaker. Around the time of the publication of the book (1901), large numbers were in use and gave very good service. a and b are the main contacts. c is the crosspiece that a and b are connected to. The current flows from a to c to b, which trips the coil d and exits out l. m is an auxiliary carbon contact, n is a carbon wiper, and w is an adjustable weight attached to the armature.
