ABSTRACT:
A substantially universal power feed for a drilling machine has a unique clutching arrangement whereby overloads are substantially eliminated. A further safety feature comprises a shear plate which functions to stop rotation of the power feed in the event of clutch malfunction or over adjustment of the clutch release spring. The power feed is also of the type that the feeders arbor may be rotated with the clutch disengaged from the motor so that the operator has a choice of using the power feed or manually feeding the drill without the necessity of physically removing the power feed from the drilling machine.
