  • Patent number: 4736658
    Abstract: An improved screw holding and driving device having a sleeve positioned on a shank of a screwdriver in surrounding relation. The interior diameter of the sleeve being sized to permit slidable rotation of the sleeve with respect to the shank. The sleeve having a ball detent device for cooperating with a groove located on the screwdriver shank to hold the sleeve in a position on the shank where the sleeve does not extend beyond the screwdriver bit. The ball detent device when engaging the groove enables the sleeve to be held in the position where the sleeve will not be used to hold a screw and at the same time permit the sleeve to be freely rotatable on the shank of the screwdriver.

  • Patent number: 4581962
    Abstract: The invention is intended for use with threaded fasteners, screws, bolts and similar devices, in their almost limitless applications to assembling objects and structures. These fasteners exist in many types, each requiring a special tool bit.On many occasions screws or other fasteners must be installed or removed in locations difficult of access and of which clear view may not be obtained, also where use of two hands is not possible. This invention is particularly intended for these situations.The invention comprises basically a combination of a barrel (11 or 811) and collar (20 or 201), preferably made of stiff but flexible plastic, which fit over and enclose a tool for threaded fasteners, either with a fixed bit or one which can accept insertable bits. The barrel (11) provides at its working or tip end a set of flexible elements (31) which act to grip screw heads and hold them registered with the tool.

  • Patent number: 4550476
    Abstract: The adapter for the torquing tool includes an elongated body having a bore in at least one end to accommodate a driver bit and a coupling means for detachably attaching the body to the tool. A depth adjustment bushing is threadably engaged within said bore, with the bushing being externally threaded to engage the bore. The bushing includes a body section and a shank section. An axial passageway extends through the shank section and an axial slot extending through the wall of the shank in communication with the passageway. A screw extends through a radial threaded opening in the body and into the axial passageway through the slot so when the driver bit is housed within the body section and extends into the passageway, it is held in place by tightening the screw. In a preferred form, the passageway has a hexagonal cross section for mating engagement with a hexagonal end section of the driving bit.
