Abstract

See full text

A tool for driving uncollated nails includes a tool body with a nose portion defining a drive track wherein a driver blade moves in drive and return strokes. A magazine carried by the body supports a row of nails, and a pusher urges the nails along a feed path toward the drive track. The magazine is adjustable for tailoring the feed path width to the nail size. Individual nails are advanced from the magazine to a drive position in the drive track by an escapement mechanism operated in timed relationship with the driver blade, and an advanced nail is held in the drive position by a magnet assembly supported by the tool nose portion. Nails are positively advanced and are properly oriented by the escapement mechanism independently of the number of nails, the pusher force, or other conditions in the magazine. The tool magazine is quickly and conveniently loaded with nails supplied in an oriented condition from a loading chute. The loading operation is automatic in response to engagement of the magazine with the chute, and does not require awkward manipulation of the pusher. Coupling members on the magazine and on the chute are mated by means of ramp and guide structures. In the mated position, stops in the nail path are opened to permit nails to slide from the chute into the magazine.
