  • Patent number: 6941847
    Abstract: A novel workpiece engaging nose body for holding a screwstrip having screws held in a strap is provided. The workpiece engaging nose body includes a nose portion and a rear portion with the nose portion slidably mounted on the rear portion for movement rearwardly when the nose is urged into a workpiece to drive a screw. An exitway is defined between the nose portion and rear portion through which spent strap from which screws have been driven exit the nose body. On urging the nose body into the workpiece, the nose portion slides rearwardly to engage the strap in the exitway and move it rearwardly into engagement with the rear portion in the exitway. The strap is preferably “pinched” in the exitway between the nose portion and rear portion to assist in locating a screw to be driven from the nose body.

  • Patent number: 6647836
    Abstract: A driver attachment (12) for a collated screwstrip (13) carrying screws (16) in which a slide body (20) is slidable in a housing (18) parallel a longitudinal axis (52) about which a drive shaft (34) is rotatable. The slide body (20) receives a screwstrip (13) such that a screw feed activation mechanism coupled between the housing (18) and the slide body (20) advances successive screws (16) into a position to be driven by the drive shaft (34) with relative sliding of the slide body (20) relative the housing (18) between an extended and a retracted position. A latch system is provided to latch the slide body (20) to the housing (18) against extension towards the extended position beyond an extension limit position. With the slide body (20) and housing (18) latched together, the drive attachment (12) may be used to drive or withdraw separate screw (16) independently of the screwstrip, with or without the screwstrip (13) engaged in the slide body (20).

  • Patent number: 6494322
    Abstract: A plastic screwstrip has a holding strip carrying a plurality of screws in a side-by-side relation as adapted for feeding, into an autofeed screwdriver. To assist in identifying which of two distal ends of the screwstrip are to be fed into the screwdriver and to assist in guiding the entry of the holding strip therein, a guide section of the holding strip forward of the first screw to be driven is provided at its front lead end with an arrow shaped forwardmost portion.

  • Patent number: 6425306
    Abstract: A nosepiece for fastener driving tools with a contact surface for engagement with the workpiece with a rounded profile to facilitate driving fasteners at an angle into the workpiece. Preferably, the contact surface has a first radially innermost portion of the contact surface for engagement of the workpiece when a screw is being driven substantially normal to the surface of the workpiece and a second outer portion of the contact surface radially outwardly from the innermost portion which outer portion is adopted to engage the work surface when a screw is being driven at an angle other than substantially normal to the work surface, the characteristics of the innermost portion of the contact surface and outermost portion of the contact surface varying such that the outer portion provides resistance to slippage of the nosepiece on the work surface when a screw is being driven at an angle to the normal.
