To load fastening elements into the muzzle end of the barrel in an explosive powder driven setting gun, a tubular shaped feeding device is pivotally connected to the housing of the gun for movement between a first position where a fastening element can be inserted into the feeding device and a second position where the tubular shaped feeding device is aligned with the muzzle end of the barrel. An ejector is movably positioned in the feeding device for inserting a fastening element into the muzzle end of the barrel. The feeding device includes a member which prevents displacement of the barrel into the firing position when the feeding device is in the second position. |
