In a roofing washer-dispensing and fastener-driving machine, which has a fastener-feeding tube, a fastener-engaging pawl is mounted operatively to the tube, near its upper end.

An elongate rod is arranged to pivot the pawl from the normal position into the pivoted position when the machine is operated. In the same machine, a magazine adapted to hold a stack of such washers is improved so as to have a bridge mounted pivotably to one of two side walls of the magazine and a cover is mounted adjustably to the bridge, so that the cover in an upwardly adjusted position is inserted into the magazine, above a stack of such washers in the magazine, when the bridge spans the side walls and so that the cover is removed from the magazine when the bridge is pivoted to a position wherein the bridge does not span the side walls. The cover is mounted to the bridge via a rod, along which the cover is movable. In the same machine, a shuttl…
