CONTINUOUS-CURRENT WINDINGS

50, 97, 98, 145, 146, as also 51 and 100, as these are the only ones 

 to which allusion has as yet been made. 



In such a diagram, it has become conventional practice to let 

 the inside of the diagram represent the commutator end, and the 

 outside the back end. The face conductors are diagram matically 

 represented by the radial lines, and the end connections by other 

 lines, the inclination or curvature of which is so chosen as to give 

 a maximum of distinctness to the diagram. 



The final practice of diagrammatically representing commutator 

 segments in winding diagrams, will be shown in a subsequent 

 figure. In the case of Fig. 156, the eight little rectangles toward

the centre of the figure will be readily recognised as intended to 

 represent the commutator segments. 



The only irregular feature of the diagram of Fig. 156 relates 

 to conductors Nos. 51 and 100. Conductor No. 100 constitutes 

 the right-hand side of the turn of which conductor No. 51 is 

 the left-hand member. Similarly conductor No. 53 is connected 

 over the back end to conductor No. (53+49), i.e. to conductor 

 No. 102. 



Thus also we have : 

 Conductor No. 1 is connected at the back end to conductor No. 50.

These steps are taken in Figs. 157 and 158, and were we to 

 carry this out all the way round the circumference, we should 

 obtain a diagram of which a portion is shown in Fig. 158.
