Abstract
Abstract A fastener driving tool includes a pointing device permitting the tool to be positioned against a workpiece so that a fastener is driven precisely at a target point. The tool includes a body with a nose portion in which is a fastener drive track. A foot assembly moves from a rest position toward the tool body to a drive position when the tool is pressed against the workpiece. In the rest position, the pointing device is aligned with the drive track and is adjacent the workpiece. When the tool is moved to the drive position, the pointing device is retracted, the nose portion approaches the workpiece, a safety mechanism is operated and a fastener is driven into the selected target point.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
217 words
A fastener driving tool for driving a fastener into a workpiece, said fastener driving tool comprising: a tool body defining a nose portion and a fastener drive track extending through said nose portion; a driver blade movable in said drive track in a fastener driving stroke; a foot assembly mounted on said tool body and having a contact portion adapted to be placed against the workpiece; slide means mounting said foot assembly for reciprocal movement toward and away from said tool body in the direction of the fastener driving stroke between a rest position and a drive position; spring means normally holding said foot assembly in the rest position in which said tool body is spaced from the workpiece and permitting said tool body to move relative to the foot assembly to the drive position in which said nose position is adjacent the workpiece; the fastener driving tool being characterized by: a pointing member carried by said foot assembly and normally disposed in an aim position in alignment with said drive track between said nose portion and said contact portion; and means responsive to relative movement of said foot assembly from said rest position to said drive position for withdrawing said pointing member away from said aim position to a retracted position clear of said nose portion.
Claim 2
Dependent Claim
217 words
A fastener driving tool for driving a fastener into a workpiece, said fastener driving tool comprising: a tool body defining a nose portion and a fastener drive track extending through said nose portion; a driver blade movable in said drive track in a fastener driving stroke; a foot assembly mounted on said tool body and having a contact portion adapted to be placed against the workpiece; slide means mounting said foot assembly for reciprocal movement toward and away from said tool body in the direction of the fastener driving stroke between a rest position and a drive position; spring means normally holding said foot assembly in the rest position in which said tool body is spaced from the workpiece and permitting said tool body to move relative to the foot assembly to the drive position in which said nose position is adjacent the workpiece; the fastener driving tool being characterized by: a pointing member carried by said foot assembly and normally disposed in an aim position in alignment with said drive track between said nose portion and said contact portion; and means responsive to relative movement of said foot assembly from said rest position to said drive position for withdrawing said pointing member away from said aim position to a retracted position clear of said nose portion.
Claim 3
Dependent Claim
36 words

The fastener driving tool of claim 2, said responsive means including a cam.
Claim 5
Dependent Claim
53 words
The fastener driving tool of claim 1, said tool further comprising a safety assembly for controlling the initiation of a drive stroke, and said foot assembly including a safety operating member for enabling said safety assembly in response to relative movement of said foot assembly from said rest position to said drive position.
Claim 6
Dependent Claim
