Fig. 4-1. Seeburg pump and spool frame. The motor and its wooden base with supporting springs is missing.
At the upper left is the large pulley driven by the motor. This pulley turns the pump crankshaft, and also
drives a rubber-tire wheel at right angles which powers the spool frame. The roll playing tempo is adjusted
by moving the rubber tire wheel closer or farther away from the center of the large pulley wheel. The large
pneumatic, visible just below the horizontal drive shaft to the spool frame, changes the spool transmission
from play to rewind mode.
