This diagram is from c.1937 and, while not exactly like your Emerson, their fans did not change much in the major details.   Your fan does not use a capacitor in the base.   Your fan has three speeds.  Your smaller fan is a single speed.

Some Emerson info:

When you slide the switch it arcs to the contacts creating a spark for a second. If it continues to spark then there definitely is a problem.
