Abstract: A fastener driving tool includes a magazine comprised of a plurality of fastener slides, each of which carries a fasteners of a different size. The magazine is designed so that an operator may to choose to drive fasteners from any of the fastener slides. In one embodiment, the fastener slides are arranged around a central core. A rod supported by the tool's base and driver fits within the central core and provides an axis of rotation for the magazine. During rotation of the magazine, each slide can be aligned with the driver. Alignment of a slide is maintained by a position locking means. A feed means in each slide forces the fasteners down the slide and into the driver. In another embodiment, the fastener slides are arranged next to one another in the magazine. Each slide can be aligned with the driver by shifting the magazine laterally. A position locking means keeps the magazine in the proper alignment once a particular fastener slide has been chosen.

Abstract: This patent discloses a floor box for a service distribution system in a concrete floor slab. The floor box has a bottom, end walls, and side walls that define an interior of the box and a frame support that is positioned within the box and engages end walls and side walls to maintain the end walls and side walls in close conformance at their junction. The frame support also supports an activation frame of an activation kit positioned within an upper opening of the floor box. The floor box is less expensive to manufacture than floor boxes that are manufactured to maintain structural integrity independent of a surrounding concrete floor slab.
