  • Patent number: 4970918
    Abstract: An apparatus and method for manipulating a fastening device such as a bolt or screw is disclosed. The apparatus comprises a handle which has a rotatable shaft inserted through the handle. A housing pivots about one end of the handle. A drive head is located in the housing and has an end which can be adopted to a socket or other device to fit the fastening device. The drive head pivots with the housing as the housing rotates about the handle. The longitudinal axis of the drive head can be aligned with the drive shaft, or the housing and drive head can be pivoted about the handle until the longitudinal axis of the drive head is perpendicular to the drive shaft, and a drive gear mechanically connects the drive shaft to the drive head. The drive shaft can be rotated to manipulate a fastening device at angles of 0.degree., 90.degree., and 270.degree. from the drive shaft.
