ABSTRACT:
A portable fastener driving tool (10) having a raceway (26) with driver blade (21, 60) reciprocating therein from a retracted position to a fastener-driven position for driving fastener (33, 61) seriatim from a fastenerstick (19, 62) positioned at an angle to the raceway. The first-to-be-driven fastener (33, 61), while attached to the stick (19, 62), is positioned in raceway (26) so that descending blade (21, 60) serves to orient the fastener (33, 61) to a position substantially parallel to the raceway (26) for driving down and out the raceway into the workpiece. Ramp means (37, 46) which form part of tool exit opening (38) re-orients fastener (33) as necessary and guides it during its exit. The fastenerstick (19, 62) may be supported in raceway (26) by detent stud means (29, 31) which retract from the raceway (26) when staple (33, 61) descends.
