A guide for use with a fastener driving tool which positions the fastener driving tool with respect to the workpiece and also controls the degree of penetration of the fastener with respect to the workpiece to allow for contraction and expansion of the workpiece due to temperature changes. The guide includes a rigid U-shaped member which may be attached to either a wire type or flat type safety yoke.

Guide for fastener driving tool

A fastener driving tool includes a guide for positioning a furniture spring clip with respect to the tool and also positions the furniture spring clip with respect to a wooden furniture frame to allow the furniture spring clip to be secured thereto. A furniture spring clip is also disclosed which includes one or more fastener receiving apertures which allow the fastener to be received in the wooden frame at a corner at approximately a 45.degree. angle with respect to adjacent perpendicular surfaces of the furniture frame. The furniture spring clip is thus adapted to be secured to a wooden furniture frame with a single fastener which provides holding power along two axes with respect to adjacent perpendicular surfaces of the wooden furniture frame.

Furniture clip/tool

A fastener driving tool for fabricating upholstered furniture and particularly for securing furniture clips, such as a J-type spring clip, to a wood furniture frame. The furniture clips are used to suspend furniture springs across the furniture frame. The tool includes a pivotally mounted magazine which prevents the tool from being operated unless the nosepiece is in engagement with a workpiece. In order to facilitate alignment of the furniture clips with respect to the fasteners, the nosepiece is formed as a guide for aligning the furniture spring clip with respect to the fastener drive track.

Furniture tool

An electric fastener driving tool includes a body of a clam-shell construction formed of two body parts that define a head and handle portions. An open bottom magazine assembly is attached to the tool for supplying fasteners to be driven. The tool also includes a removable nose piece defining a portion of a drive track for a driving blade mounted in the tool. The nosepiece includes different workpiece engaging surfaces on opposite ends such that the tool may be used to drive fasteners into different types of workpieces. The tool further includes a double cone spring for returning the driver to its at rest position.
