Abstract
An apparatus is disclosed for forming bores in articles, such as lumber studs which includes a conveyor operable for transporting the studs to a work station. Disposed adjacent the work station is a charging mechanism operable for isolating a predetermined course of the studs from the conveyor at the work station and maintaining the course substantially stationary. Drill sets are mounted on the charger and beneath the course and are operable for selectively shifting vertically upwardly for drilling bores in the course. The charger includes a carriage assembly which is disposed beneath the conveyor selectively operable for reciprocal vertical shifting to lift the course from the conveyor and return the course thereto. The drills are rigidly mounted on the carriage assembly and are moveable therewith. Additionally, the carriage assembly is provided with a lift element which is mounted thereon by means of a resilient mounting. The upper surface of the lift element is normally biased above the penetrating ends of the drills.
