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).

Nail driving tool

The present invention comprises a nail driving device with a magazine for nails held together in nail strips, with a nail transport device, wherein the nail strips are pressed in the direction of a fixed stop surface by means of a spring element, and moved in the direction of the exit channel of the device mouthpiece. In order to be able to work with nail strips in which the nail shafts are spaced apart, but rather lie shaft against shaft, it is provided that the nail transport device has a transport shuttle which can be moved in the longitudinal direction of the magazine using the piston rod of the feed cylinder, and which has a wedge-shaped nail strip separating element which is operative during the reverse movement of the shuttle such that the transport element is formed as an advance clamp which grasps the separated nail strip laterally during the forward movement of the transport shuttle in such a way that the nail strip resting against the stop surface can be clamped between the transport shuttle and the advance clamp by means of spring action, and can therefore be moved forwardly along with the transport shuttle.

Nail driving device

An annular cushioning buffer (1) is fabricated from an elastic material, such as, for example, polyurethane, for use in connection with fastener-driving tools for impact load distribution and energy absorption purposes. The buffer (1) includes an axially central passage (2) having an axis (M), as well as a plurality of axially extending holes (3) equiangularly spaced about the annular buffer (1) along a circular locus thereof. Radially extending slots (6) extend toward and open onto or pierce inner and outer peripheral or circumferential surfaces (4,5) of the buffer (1) in an alternative fashion so as to uniformly distribute the load impressed upon the buffer (1) by means of the striking piston of the fastener-driving tool.
