To quickly assess the difficulty of the text, read a short excerpt:
Then, if there are partitions between each of the coils, as in figure 17 or 18, start at the upper section No. 1, and wind one coil, connecting its end temporarily with its beginning, and marking them, if desired, B and E. Then turn the armature around half a revolution, and starting in the same way wind the neighboring coil No. 2, figure 1 7, precisely similarly, connecting its ends to- gether and marking them as before. Then turn the armature again for half a revolution and wind No. 3, and pr...oceed thus, turning the armature one-half a revolution after each coil is completed. When it is com- pleted, there will be a regular series of beginnings and ends of coils along the periphery of the armature, and they will all be in their proper relative positions. Untie the ends and connect the one marked E (end) of any one coil with the next one marked B (which will be in the next but one section) and with one commutator bar ; the one marked E of this coil connect with the next B, and so on. By winding it as described it will be found to be almost im- possible to make a mistake in the connections or in the proper location of the coils belonging to different sides of the commutator.
