The winding shown in Fig. 22 is of a totally differenttvpe. The convenient arrangement of two btushes on thequarter is accomplished by winding the armature so, thatthe similar bobbins are placed in series instead of tracing out the current in the winding of Fig. 22 it willbe seen that there are two paths through the armature,instead of four as in Fig. 21. Other things being equal,this has the object of doubling the torque and halving thespeed that would occur were the armature parallel speed and po
