ABSTRACT:
In a powder driven fastening tool, a channel is included for feeding a strip of explosive powder cartridges to a firing mechanism. A trigger is included for actuating the firing mechanism, wherein the trigger is movable between a first position and a second position. An advancing lever is pivotally coupled to the tool, the advancing lever having a strip engagement portion for indexing the strip which extends into the channel. An advance link is cammingly engaged with the advancing lever and is operationally associated with the trigger so that the strip engagement portion is in a first position in the channel when the trigger is in the first position and so the strip engagement portion is in a second position when the trigger is in the second position.
