ABSTRACT:
A nail driving tool is disclosed as including a magazine (9) which, in turn, includes a guide path (7) for guiding a plurality of nails (10.sub.1, 10.sub.2, 10.sub.3. . . ) which are preferably disposed in the form of a nail strip. The guide path (7) is open at an outlet opening (2) from or through which a first or leading nail (10.sub.1) is conveyed into a discharge channel (3). A driving mechanism, such as, for example, a pneumatic driver (11) is disposed within the discharge channel (3) for driving or discharging the leading nail (10.sub.1) from or through the discharge channel (3). A cantilevered leaf spring (8) has one end thereof fixedly mounted upon the magazine (9) while the opposite free end thereof engages the second nail (10.sub.2) disposed immediately upstream of the leading nail (10.sub.1) so as to retain all of the nails disposed upstream of the leading nail (10.sub.1) while the leading nail (10.sub.1) is disposed in its readied state for discharge from the discharge channel (3) by the driver (11). A magnet (4) is disposed within a blind bore (6) upon the opposite side of the discharge channel (3) with respect to the outlet opening (2) for retaining the leading nail (10.sub.1) within the discharge channel (3) at its readied disposition for discharge by the driver (11). A bottom or end wall (5) of the blind bore (6) serves as a protection device for protecting the magnet (4) from the nails as the latter are serially conveyed into the discharge channel (3).
