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.

[ What is claimed is:] [1.] A fastening device, which comprises:a housing;a fastener guide mounted on the housing for supporting selectively fasteners of either of at least two distinctly different configurations in position to be driven from the device, the fastener guide having structure which guides the fasteners of the at least two configurations from the housing in substantially their pre-driven configurations; whereinthe fastener guide further includes a surface adjacent at least a portion of the fastener being guided, the surface forming a surface of a wall, and a groove formed in the surface which guides the portion of the fastener as the fastener is being driven from the housing;the wall is formed with a ledge at one end thereof and an edge at the opposite end thereof with the surface extending therebetween;one end of the groove is formed in the ledge and extends along the surface toward the edge, wherein the groove is formed with a base which is tapered toward the surface from the ledge as the groove extends toward the edge to a juncture of the base with the surface; and further comprisinga striker mounted on the housing for engaging and driving the fasteners from the device;a spring biasingly coupled between the housing and the striker;a lever assembly mounted on the housing and removably coupled to the striker for moving the striker to a "load" position against the biasing action of the spring; anda structure located in the housing for decoupling the lever assembly from the striker when the striker has been moved to the "load" position whereby the striker moves toward and drives the fastener from the housing.
