Abstract
A pneumatically actuated tool for setting blind rivets of the type having a body, a head and breakaway pull mandrel. The tool comprises a body having a double-acting cylinder therein, a handle attached to the body, a guide body affixed to the body beneath the cylinder, a pull track in the guide body for the rivets and a bore in the body connecting the cylinder and the pull track, the cylinder, the bore, and the pull track being coaxial. The tool is provided with a rivet pickup and pull mechanism comprising a lower load piston having a downwardly depending tubular assembly slidable within the body bore and pull track and terminating in a nose piece, and an upper pull piston having a downwardly depending tubular assembly telescopicly and shiftably located within the lower load piston tubular assembly and terminating in a chuck provided with mandrel-engaging jaws. The tool has a magazine connected to the guide body and containing a strip of rivets. An automatic rivet feed mechanism is provided comprising a shiftable feeder shoe and pawl for advancing the forwardmost rivet of the strip into the guide body pull track, a ratchet for preventing the strip from shifting away from the guide body pull track, and means to hold and center the forwardmost rivet in the guide body pull track. The tool is further provided with pneumatic sequencing controls which provide full cycle-through control, such that the tool, once triggered, will perform the full cycle, and the next cycle cannot be started until the trigger is released at the end of the previous cycle.
