Case 3809 STAND-UP SCREWGUN FOR LONG FASTENERS ABSTRACT A standup screwgun having the capacity to drive twelve inch fasteners. The feed tube merges with the guide tube at a shallow angle enlarging the interface between the two tubes. Two triangular panel members extend along the interface with a first side of each lying generally on the inner cylindrical surface of the guide tube, a second side lying generally on the inner cylindrical surface of the feed tube and the third side extending angularly between the two tubes forming an inclined camming surface. The panels are spaced apart a distance capable of receiving the fastener shank but less than that of the fastener head. The leading end of the fastener is transferred gradually from the feed tube to the guide tube while the head is cammed laterally over a short length. This same or additional structure can prevent a misoriented fastener from reaching the guide tube and creating a jam.
