Abstract
A holding or checking means for holding the control rod of a reciprocating drill feed control apparatus in position after each advancing movement of an automatic drilling machine during a 'peck drilling' operation. The holding means includes a cylindrical body adapted to be fastened over the end of a drill feed control apparatus and with the control rod of the feed control apparatus extended through said body. A pair of pivotally mounted yoke arms are mounted on a cylindrical body and have semi-circular recesses adapted for friction holding engagement with the feed control rod to hold it in an advanced position when the reciprocating drill apparatus is retracted. The holding means includes a biasing means for biasing the yoke arms into friction engagement against the control rod. The holding means includes a fluid operated piston for selective movement into engagement with the yoke arms for releasing the yoke arms from a friction engagement with the control rod to permit the control rod to be moved by the feed control apparatus to an initial operating position.
