Vertical meaning the shaft points either up or down?

And here you lost me...

So, the two brass pulleys, the  panel-mounted tuning shaft, and the slide-rule 
dial itself are all in one plane, but the large pulley on the tuning cap is in a 
different plane, perpendicular to the first? 

I cannot visualize how the string gets from one plane to the other without two 
more pulleys.
