Abstract
A power driven screw driving tool having a screw holding nosepiece detachably mounted to its end, the nosepiece having slidable sleeve members cooperable with ball elements to obtain an initial locked condition of a screw entered into the nosepiece for positioning the screw relative to the work, and being cooperable with one another to obtain a released condition to permit the screw to be finally driven out of the tool into the work. A first embodiment describes the nosepiece as adapted for use with a tool in which the spindle and driving bit are restrained against axial movement relative to the housing. A variation of the first embodiment describes the nosepiece as having a screw back-up sleeve as being fixed to an inner sleeve, rather than relatively slidable as in the first embodiment. And a further embodiment discloses a modified form of the sleeves and back-up element in a nosepiece associated with a clutch engageable spindle and bit, the back-up element in this embodiment being adjustable according to variations in the heads of screws to be accommodated.
