I would still like to see a better quality schematic to be sure the third brush is grounded but assuming it is, I may have figured it out. If so I need to rethink the direction of flow.

The explanation will probably get scrambled in the typing and I could still be all wet but if my understanding is correct, the grounded third brush is the 0 point of both the armature and field coils. The other two brushes provide the connections to complete the series arrangement as well as provide the output. Because of the way two or more armature windings connect to a single commutator segment the series portion utilizes windings in the armature to complete the series circuit. The shunt coil takes the output voltage and goes directly to ground for the parallel portion. The third brush moves to change the relationship of how far away a particular commutator bar and its connected armature windings and poles might be from a field shoe before it connects and disconnects -- effectively subtracting or adding armature windings to the total to control the max output. Farther away and a lower magnetic strength gives a lower output, nearer is higher.

Anyway, until I can read a professional explanation that is my current theory.
