The half circles and a rivet passed through,uniting them, lock the parts of a hinge. Upon this split ringis slipped a fiat helix of wire, forming the entire winding ofthe armature in one layer, so that the operation of slipping iton is very simple. The wire used is flat, as shown in Fig. small i horse-power C. & C. niotor, shown in Fig. 17, is interesting as being madewith a complete Wheeier regulator, by which it can be run at any speed. The Thomson-Houston stationary motor, shown in Fig. 18, is made m different sizes,from 1 to 15 horse-power. The proportioning is such that, supplied with a constant poten-tial, they are practically self-regulating as regards speed, though the load be varied from.

At the same time the brushes on the commutator runwithout spark, and are not shifted in position during extreme changes of load on the other words, the non-sparking points of the commutator remain at one position without
