Abstract
A mechanical quill having selective braking capability, achieved by a pneumatic cylinder (110) mounted to one motor (80) for selectively driving a braking member (120) into a braking material (104) coupled to a motor armature (84). This braking member (120) interrupts a clutch-type drive path through the motor as desired, to prevent advance of a quill.
