brake
When pressed, the brake pedal (see figure 17)
actuates mechanical linkage that expands brake
shoes within the spindle drive pulley and stops
the lathe spindle. At the same time the motor
power supply circuit is cut by a linkage-controlled
limit switch. to resume lathe operations after the
brake has been used, return the spindle on/oFF
lever to the central position, and all lathe controls
become "live" again.
