Abstract
The present power driver handles fasteners of varying length mounted on a strip or belt, through a touch-down foot which accommodates fasteners of different length to eliminate wasted motion of the driver. The fasteners are also prevented by said touch-down foot from tipping or going into a workpiece at an angle. The depth to which the fasteners are driven into the workpiece is controllable and any irregularities in the mounting of the fasteners on the strip or belt are compensated.
Claims6
An apparatus for automatically power driving fasteners such as screws or the like which are joined together in a strip, comprising housing means, power drive means operatively supported by said housing means, driving spike means operatively connected to said power drive means and defining a longitudinal axis, guide means connected to the housing means, supporting body means movably mounted in the guide means for displacement parallel to the axis of said driving spike means, spring means operatively connected to said supporting body means for biasing said supporting body means against said displacement, guide channel means for said fastener strip extending through said supporting body means, fastener feed advance means mounted in said supporting body means and actuated by movement between said housing means and said supporting body means, touch-down foot means, and means mounting said touch-down foot means to said supporting body means for displacement and adjustment of said touch-down foot means parallel to said longitudinal axis of said driving spike means, said touch-down foot means properly guiding said fastener.
