Abstract
A fastening device 100 includes a striker 260 for driving fasteners 129, such as staples 130 and nails 131, from the device and into a workpiece 396. The device 100 includes a fastener feed track 128 and a nosepiece 140 at the forward end of the track to guide the leading fasteners 129 into a discharge space 379 for ultimate driving of the lead fastener by the striker through the discharge space and from the device. The nosepiece 140 is formed with a groove or steep slope 402 adjacent the discharge space 379 which the nails 131 to move gradually laterally into the space for proper positioning of the nails as they are being driven through the space by the striker 260. The striker 260 is formed with a notch 406 in a portion of the surface of the striker which engages the fasteners 129 to drive the fasteners from the device 100. The notch 406 forms a nest which captures a head 392 of the nails 131 to prevent the nails from moving substantially laterally into the discharge space 379 as the nails are being driven from the device 100.
