An improved fastener driving tool is provided that is especially adapted to the application of fasteners in trim applications, such as the fastening of wood trim and decorative pieces. The preferred embodiment is a combustion tool, and includes an incrementally adjustable fastener driving depth setting mechanism. The incremental control permits an operator to select from a number of discrete depth settings over a limited range. The preferred tool also includes a distance amplifying fastener lockout. The lockout amplifies a fastener follower movement permitting the blocking of movement of a linkage necessary to tool operation in response to the movement associated with an individual small fastener being dispensed. A trigger and handle of the preferred tool are proximate to the driver blade axis, and the trigger is disposed within an imaginary extension of a fuel canister held within the tool housing. A unique fastener magazine extends into the nosepiece, includes ribs for holding separate pieces of the tool housing together, and includes a solid bottom portion preventing exposure of fasteners held in the tool. An elongated joining element serves to hold the housing pieces together along the front of the tool, and provides a sight permitting an operator to properly align the tool over a workpiece. A battery holder in the tool includes separate locked operational and standby positions. The standby position prevents contact with tool circuits so as to electrically disable the tool.

[ What is claimed is:] [1.] A powered tool constructed to axially drive a driver blade in response to power from a power delivery source so as to impact a fastener and drive said fastener into a workpiece, comprising:a housing having a main chamber enclosing said power delivery source;a nosepiece associated with said housing so as to accept a fastener and axially guide said driver blade toward impact with said fastener;a handle;a trigger permitting an operator to actuate said power delivery source;a fastener supply assembly associated with said housing for supplying fasteners into said nosepiece;a workpiece contacting depth adjustment probe mounted upon said housing so as to be axially movable inwardly and outwardly with respect to said nosepiece over a limited range;a threaded adjuster rotatable mounted upon said workpiece contacting depth adjustment probe and being threadedly engaged at a first location thereof with said workpiece contacting depth adjustment probe so as to be responsive to operator manipulation and thereby be able to axially move said work-piece contacting depth adjustment probe over said limited range as a result of rotation and threaded engagement of said threaded adjuster with said workpiece contacting depth adjustment probe; andfirst and second incremental controllers mounted upon said threaded adjuster at a second location of said threaded adjuster, which is remote from said first location of said threaded adjuster at which said threaded adjuster is threadedly engaged with said workpiece contacting depth adjustment probe, and cooperating together for dividing said limited range into a discrete number of increments.
