A magazine for a nail-driving tool, which may be pneumatically powered or combustion-powered, is arranged to store a plurality of plural nail strips in side-by-side relationship. A spring-biased mechanism is used to bias the stored strips toward a side rail. Being movable along a frame between an advanced position and a retracted position, a feeding member in the retracted position engages the shank of an endmost nail of the stored strip nearest to the side rail. A negator spring mechanism biasing the feeding member toward the advanced position includes a leaf spring arranged to be longitudinally pulled between the nail heads of the stored ship nearest to the side rail and the nail heads of the next strip when the feeding member is moved from the advanced position into the retracted position. The feeding member has a wedging portion arranged to push between some of the nail shanks of the stored strip nearest to the side rail of the magazine and some of the nail shanks of the next strip and to lead the leaf spring when moved from the advanced position into the retracted position and a rail-engaging portion arranged to push between the side rail and some of the nail shanks nearest to the side rail when moved similarly. In an operative position, in which it can be releasably latched, a biasing member bears against the nearest strip. A floor member can be adjustably positioned. When latched, the biasing member latches the floor.

In a fastener-driving tool comprising a housing structure defining an axis and a nosepiece extending from the housing structure, a primary actuating structure is movable between a tool-disabling position and a tool-enabling position, and a secondary actuating structure is coactive with the primary actuating structure for moving the primary actuating structure to the tool-enabling position when the secondary actuating structure is pressed firmly against a workpiece. The primary actuating structure is biased to the tool-disabling position by a primary spring or springs. The secondary actuating structure is biased away from the primary actuating structure by secondary springs. When the secondary actuating structure is pressed firmly against a workpiece, the primary spring or springs exhibit a biasing force less than the biasing force exhibited by the secondary springs. The secondary actuating structure may also be biased away from the housing structure by a tertiary spring.

In pneumatically powered combustion-powered fastener-driving tool including a nosepiece, a mechanism is provided for positioning the tool relative to an opening in a workpiece to be fastened to another workpiece. A probe connected to an actuator used in such a tool, preferably via a spring strip, so as to be laterally movable extends into the opening to align the nosepiece so that a fastener can be precisely driven. The probe has a surface engageable by a driven fastener to move the probe laterally and from the opening as the tool recoils. Optionally, a guide spaced from the probe and mounted pivotally is adapted to bear against the workpiece with the opening. The probe and the guide have respective grooves defining a channel for guiding a driven fastener.

The disclosed partitioned wastebasket has component pieces including an outer receptacle, one or more partition inserts, and a cover, operatively interfitted relative to one another. The outer receptacle has a bottom wall and a side wall upstanding therefrom to an open upper top, and opposing handles are formed adjacent the open upper top. Each partition insert is sized to fit closely adjacent the outer receptacle walls, and has front and rear hooks that thereupon become operatively interfixed to the outer receptacle to hold each partition insert within the outer receptacle and to hold the outer receptacle side wall against outward flexture. Hinge structure between the cover and each partition insert movably supports the cover for opening and closing the outer receptacle. The outer receptacle side wall diverges away from the bottom wall to allow like outer receptacles to be compactly nested together for shipment before assembly, and the handles of adjacent outer receptacles engage before the side walls do to ease separation of adjacent outer receptacles for assembly.
