Abstract
Method and apparatus for inserting fasteners into holes in a workpiece. The apparatus includes a finger carrying device which is carried by an anvil for telescoping movement relative to the anvil, the finger carrying device includes a bore coaxial with the anvil and through which the anvil may pass as it moves from a raised position to a lowered position. The finger carrying device is provided with a side port through which fasteners may be inserted by a gravity injector, the side port being disposed below the anvil when it is in its raised position. A plurality of annular arrays of resilient fingers are mounted in the bore below the side port. A fastener, after being injected into the bore of the finger carrying device, is pushed by the anvil through the fingers as the anvil moves to its lowered position, the annular arrays of resilient fingers properly orienting the fastener in coaxial alignment with the anvil and with a hole in a workpiece.
